FIXES in 2.4.2-BETA-13

-----------------------------------------------------------------------------
Tickets 23 from <[email protected]> and 96 from
<[email protected]> reported a problem with compliing wu-ftpd on
OSF. This is due to an failure in the software to include the correct
include file. This is fixed in this release.
-----------------------------------------------------------------------------
Ticket 157 from Albert Lunde <[email protected]> pointed out an
inconsistency in the forward definition of realpath when a STDC compiler is
used. This is now fixed.
-----------------------------------------------------------------------------
Ticket 161 from [email protected], ticket 168 from [email protected] and
ticket 220 from [email protected] all pointed out a problem in the code I
put into popen.c to attempt to address an overflow problem. Too much late
night coding for me:-). Anyway, a version of their suggested fix is in
this release.
-----------------------------------------------------------------------------
Ticket 162 and 222 from [email protected] and [email protected],
respectively, pointed out that there was an extra %s in one of the
reply strings. This is now fixed
-----------------------------------------------------------------------------
Ticket 168 from [email protected] suggested that sysconf be used to
get the number of fds. This has been added to popen.c and a change has been
made to config.hpx to use that. I have also tried to add this to other
configurations that are documented (or are known) to support sysconf.
-----------------------------------------------------------------------------
Ticket 180 from David Pesticcio <[email protected]> pointed out some problems
with the INSTALL file. There was a missing step and other problems. These have
been fixed for this release.
-----------------------------------------------------------------------------
Ticket 182 from <[email protected]> supplied some fixes to skey support. The
patches supplied were used as a basis for those fixed included in this release.
-----------------------------------------------------------------------------
Ticket 183 from <[email protected]> supplied a patch to removed \r\n from any
string put in setproctitle. This changes are includes in this release.
-----------------------------------------------------------------------------
Ticket 184 from <[email protected]> supplied a patch to enforce FreeBSD (when
this software is built on FreeBSD) concerning the logging of numeric addresses
when DNS name is larger than UT_HOSTSIZE field.
-----------------------------------------------------------------------------
Ticket 185 from <[email protected]> suggested that we should removed all
references to LOG_TOOMANY, since it is no longer being actually implemented.
We agree.
-----------------------------------------------------------------------------
Ticket 186 from <[email protected]> said that FreeBSD already had the fnmatch
function in its C library and didn't need the version in the support library.
The support library will now be built without this.
-----------------------------------------------------------------------------
Ticket 191 from Ian Willis <[email protected]> suggests that the failsafe number of
fds in popen.c should be bigger than sizeof(long). He suggested 20, but I am
setting it to 31. We'll see if that helps folks have fewer signal 10 or 11
errors that are unexplained.
-----------------------------------------------------------------------------
Ticket 193 from <[email protected]> pointed out that ftpcount.c does not
include stdlib.h, which will cause malloc to allocate too little space to
hold st_size on FreeBSD. This is now fixed.
-----------------------------------------------------------------------------
Ticket 197 from Ian Willis <[email protected]> provides some additional patches
for SCO OpenServer 5. These are included in this release.
-----------------------------------------------------------------------------
Ticket 216 from Alain Magloire <[email protected]> provides
some bounds checking ftpd when building the directory command to send to
the operating system. His changes may not be portable to all platforms, since
the use snprintf, but we'll give it a try.
-----------------------------------------------------------------------------
Ticket 220 from [email protected] showd some coding problems in access.c when
determining host access information. This fix is included in this release.
-----------------------------------------------------------------------------
In researching other problems, I noticed that setproctitle was not being
called correctly in a couple of placed in ftpd.c. There were not enough
arguments. This is now fixed.

Dear Sir,

I am doing a project relative with ftp client and server sides.
I already installed the server part of ftp on SUN OS from
ftp://ftp.academ.com/pub/wu-ftpd/private/wu-ftpd-2.4.2-beta-11.tar.Z .

But I can not find the best client side ftp running on SUN OS to
connect with your ftp server. Did you develop a client ftp on SUN OS
to connect with ftp server ?

Would you please tell me where I can find the best ftp client on SUN OS
to connect with your ftp server ?

Thank you very much !

Moyang

In article <[email protected]> you wrote:
: Here's how i did something like that, but for anon instead of real..

Let me get this straight:
- one of you is trying to create an anon-only server
- one of you is trying to create an non-anon server

correct?
why wouldn't you use the ANON_ONLY flag in the Makefile in the first case
and add 'ftp' to the ftpusers file in the second case.

Subject: Closed wu-ftp-bugs tickets
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Status: OR

This file contains tickets I have closed because I could not reproduce the
problem under beta-12. I can't fix problems I can't reproduce. If you
feel that they should be reopened, send mail to "[email protected]"
and report your problem again. Note the old ticket number in the message.

-------------------------------------------------------------------------------
Ticket 5 from "Scott J. Ellentuch" <[email protected]> reported the
Beta-11 server would not work properly in setting the modes and ownership
using the upload directive. I could not reproduce this in the Beta-12 server,
so I have closed this ticket.
-------------------------------------------------------------------------------
Ticket 16 from "Scott J. Ellentuch" <[email protected]> reported the
Beta-11 server would report any users when invoking ftpwho or ftpcount on
Linux 1.2.13. I could not reproduce this in the Beta-12 server, so I have
closed this ticket.
-------------------------------------------------------------------------------
Ticket 17 from [email protected] (Kevin Geddie) reported problems when
doing anonymous logins to a BSDI 2.1 machine running the Beta 11 server.
He reported that after login via anonymous, an "ls" would generate a 421
error. I can't reproduce this on the Beta-12 server, so I have closed this
ticket.
-------------------------------------------------------------------------------
Ticket 30 from [email protected] reported a problem with the virtual
host support that was resolve in beta-12. This ticket is closed.
-------------------------------------------------------------------------------
Ticket 37 from "Gene Buckle" <[email protected]> reports the Beta-11 virual
hosts did not work on SunOS and shadow password support did not work on Linux.
I can't reproduce ether of these problems, so I am closing this ticket.
-------------------------------------------------------------------------------
Ticket 40 from [email protected] reports that when nodirs is specified,
directories could still be made if the parent directoy mode permitted it. I
can reproduce this in beta-12, so I am closing this ticket.
-------------------------------------------------------------------------------
Ticket 82 from Jawaid Bazyar <[email protected]> reported a problem in
beta 10 that related to ACL processing. This bug was fixed in beta-11.
I have closed the ticket.
-------------------------------------------------------------------------------
Ticket 88 from [email protected] and ticket 217 from [email protected] (Bruce
Cheng) reporting a problem that appeared to be related to no having a "-a" in
the /etc/inetd.conf to cause it to read the ftpaccess. These tickets are
closed.
-------------------------------------------------------------------------------
Ticket 94 and 95 from [email protected] reported that he can't get the -a
option to execute in linux. I can't reproduce this problem, so I am closing
this ticket.
-------------------------------------------------------------------------------
Ticket 158 from Peter Bivesand <[email protected]> and 212 from
Gregory Neil Shapiro <[email protected] both attempted to build beta-12
on Digital Unix using "./build osf" instead of "./build dec". These
are closed.
-------------------------------------------------------------------------------
Ticket 178 from Tim Osburn <[email protected]> appeared to indicate that he did
not do a "./build clean" before doing a "./build sol". In any case, I can't
reproduce the problem he reported with building on Solaris 2.5.1 so I have
closed the ticket.
-------------------------------------------------------------------------------
Ticket 179 from Joseph Arceneaux <[email protected]> offered some patches for
beta-11 (not included in his mail), but beta-12 was already released.
I have closed this ticket.
-------------------------------------------------------------------------------
Ticket 187 from James Sneeringer <[email protected]> said that there was an
error in the pathmsg described in the ftpaccess.5. It is escaped in the
version I have. Perhaps his version of nroff is not processing that like
mine. In any case, it's not a problem I can reproduce, so I am closing
the ticket.
-----------------------------------------------------------------------------
Ticket 192 from "Alexander V. Lukyanov" <[email protected]> reported
a bug in beta 11 that is fixed in beta 12. He asked that the ticket be
closed and it is.
-----------------------------------------------------------------------------
Ticket 196 from Ko Byung-Ho <[email protected]> was attempting to use
the cc that uses the ucb include files on Solaris 2.5 to build wuftpd. After
he discovered he should use the regular includes (via SunPRO C), all compiled
and worked just fine. This ticket is closed.
-----------------------------------------------------------------------------
Ticket 206 from Stan Pawlukiewicz <[email protected]> and 207 from
Joe Johnson <[email protected]> both reported the bug in beta-10 that was
fixed in beta-12. These tickets are closed.

Subject: Academ version of wu-ftpd 2.4 Release 2 Beta 13 available for testing
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Status: OR

BETA 13 is now available. It has been tested on the following systems:

Solaris 2.4 Sparc and x86, SunOS 4.1.4, FreeBSD 2.1.5-RELEASE, BSD/OS 1.1,
BSD/OS 2.1, Unixware 2.1, SCO Open Server 5, Linux 1.3.39 and 2.0.0.

I would like to hear from folks with access to HP-UX, Digital Unix, IRIX
and AIX in particular. Please send mail to the [email protected]
address.

If hardware companies wish to donate equipment running their proprietary
UNIX derivatives to me for doing maintenance work on this and the other
packages I maintain (NNTP, RN, etc), please contact me directly to discuss.

If software companies that sell UNIX derivatives I don't to which I don't
have access wish to donain copies of their UNIX derivative to me for the
purposes of doing maintenace work on this and the other packages I maintain,
please contact me directly to discuss.

Finally, both The AUS-CERT and the CERT/CC have continued to provide me
with feedback on the security issues with this software.

This is another release candidate.

The location is:
ftp://ftp.academ.com/pub/wu-ftpd/private/wu-ftpd-2.4.2-beta-13.tar.Z

NOTE: This directory is protected. Attempts to use a directory listing
command will fail.

-0-FIXES IN THIS RELEASE-0-

-----------------------------------------------------------------------------
Tickets 23 from <[email protected]> and 96 from
<[email protected]> reported a problem with compliing wu-ftpd on
OSF. This is due to an failure in the software to include the correct
include file. This is fixed in this release.
-----------------------------------------------------------------------------
Ticket 157 from Albert Lunde <[email protected]> pointed out an
inconsistency in the forward definition of realpath when a STDC compiler is
used. This is now fixed.
-----------------------------------------------------------------------------
Ticket 161 from [email protected], ticket 168 from [email protected] and
ticket 220 from [email protected] all pointed out a problem in the code I
put into popen.c to attempt to address an overflow problem. Too much late
night coding for me:-). Anyway, a version of their suggested fix is in
this release.
-----------------------------------------------------------------------------
Ticket 162 and 222 from [email protected] and [email protected],
respectively, pointed out that there was an extra %s in one of the
reply strings. This is now fixed
-----------------------------------------------------------------------------
Ticket 168 from [email protected] suggested that sysconf be used to
get the number of fds. This has been added to popen.c and a change has been
made to config.hpx to use that. I have also tried to add this to other
configurations that are documented (or are known) to support sysconf.
-----------------------------------------------------------------------------
Ticket 180 from David Pesticcio <[email protected]> pointed out some problems
with the INSTALL file. There was a missing step and other problems. These have
been fixed for this release.
-----------------------------------------------------------------------------
Ticket 182 from <[email protected]> supplied some fixes to skey support. The
patches supplied were used as a basis for those fixed included in this release.
-----------------------------------------------------------------------------
Ticket 183 from <[email protected]> supplied a patch to removed \r\n from any
string put in setproctitle. This changes are includes in this release.
-----------------------------------------------------------------------------
Ticket 184 from <[email protected]> supplied a patch to enforce FreeBSD (when
this software is built on FreeBSD) concerning the logging of numeric addresses
when DNS name is larger than UT_HOSTSIZE field.
-----------------------------------------------------------------------------
Ticket 185 from <[email protected]> suggested that we should removed all
references to LOG_TOOMANY, since it is no longer being actually implemented.
We agree.
-----------------------------------------------------------------------------
Ticket 186 from <[email protected]> said that FreeBSD already had the fnmatch
function in its C library and didn't need the version in the support library.
The support library will now be built without this.
-----------------------------------------------------------------------------
Ticket 191 from Ian Willis <[email protected]> suggests that the failsafe number of
fds in popen.c should be bigger than sizeof(long). He suggested 20, but I am
setting it to 31. We'll see if that helps folks have fewer signal 10 or 11
errors that are unexplained.
-----------------------------------------------------------------------------
Ticket 193 from <[email protected]> pointed out that ftpcount.c does not
include stdlib.h, which will cause malloc to allocate too little space to
hold st_size on FreeBSD. This is now fixed.
-----------------------------------------------------------------------------
Ticket 197 from Ian Willis <[email protected]> provides some additional patches
for SCO OpenServer 5. These are included in this release.
-----------------------------------------------------------------------------
Ticket 216 from Alain Magloire <[email protected]> provides
some bounds checking ftpd when building the directory command to send to
the operating system. His changes may not be portable to all platforms, since
the use snprintf, but we'll give it a try.
-----------------------------------------------------------------------------
Ticket 220 from [email protected] showd some coding problems in access.c when
determining host access information. This fix is included in this release.
-----------------------------------------------------------------------------
In researching other problems, I noticed that setproctitle was not being
called correctly in a couple of placed in ftpd.c. There were not enough
arguments. This is now fixed.
-----------------------------------------------------------------------------
A new version of vsnprintf (and the addition of snprintf) has been made to
the support library. This version comes from sendmail 8.8.5 (thanks, Eric!)
and is quite an improvement over my previous lame effort.
-----------------------------------------------------------------------------
I have also attempted to tune up all the configurations for systems to which
I have access. Those systems I don't have access may or may not work.

I think I may have set up beta-12 wrong, after the move from SunOS4 to SunOS5.
It used to work, but now I get:

220 ftms FTP server (Version wu-2.4.2-academ[BETA-12](1) Wed Jan 22 10:00:49 CST 1997) ready.
Name (ftms:brown): ftmsftp
530 421 Service not available, remote server has closed connection
Login failed.

Did I do something stupid?

Thanks in advance.

I'm using a script to kill off ftp jobs that are over 24 hours. These are
sensed on my Solaris 2.4 system because that's when the time entry changes
to a date in the 'ps -ef' listing. This means they end up hanging around
for anywhere from 24 to 36 hours since I run the script twice a day.

Hello,

I'm trying to setup a secure ftp dropbox on a BSDI UNIX server for our ISP and am having difficulty in a couple of areas.

The first problem has to do with the 'ls' command. In short, it refuses to display any files or directories when executed within wuftp. It works fine from within the account in UNIX, but not from with ftp.

The next problem of note is the fact that when I'm ftp'd into the secure account, ftp allows me to escape to a shell (even though the shell is setup as /etc/ftponly) and traverse the directory tree from the root on down.

I suspect that I'm just not getting the ftpaccess config'd right, but the documentation is skimpy at best and I could really use some insights.

Any help would be greatly appreciated.

Best regards,

guestserver does not seem to be documented in the man page. Is this
a permanent feature or a short lived one ?

This is what I grabbed from the code.

-----------------------------
guestserver [<machine1> [<machineN>]]

If present in the ftpaccess file anonymous access is restricted to
the machines listed, usually the machine whose CNAME on the current
domain is "ftp"...

"guestserver" by itself forbids anonymous access on all machines.

"guestserver ftp inf" will allow anonymous access from the two
machines whose CNAMES are "ftp.enst.fr" and "inf.enst.fr".

If anonymous access is denied on the current machine, the user will
be asked to use the first machine listed (if any) on the "guestserver"
line instead:

530- Guest login not allowed on this machine,
connect to ftp.enst.fr instead.
-----------------------------

Should this be supported as part of the virtual FTP support ?

I'm still working on the problem (in some spare time) as to why dir doesn't

.......

Then it repeats the last line forever. Or at least it would have if I didn't
hit ^C :-)

Anyone have any clues, because I sure don't? From what I can see, it
opens all of the library files just fine, but croaks at doing the ls.

So, do you have a /dev/zero file under you're chroot'ed directory?
Has it been created correctly.

I've discovered the following situation and have three users to show the point:

anonymous /bin/true
ftmsftp /bin/false
brown /usr/local/bin/zsh

The first user is obvious. The second user has been set up to chroot to a
particular area of the ftp file area, without being able to go anywhere else
in the system. Can't even get the the generic ftp area. The third is me,
a normal user.

The first two get nothing displayed when doing "dir". I see a correct listing
when doing "dir".

Is it me, or is ftp trying to start a shell in order to process the dir
command? Well, it can't if there isn't a real shell available for the
users. Is this a catch-22 situation?

OOOPS .. well .. I said I am tired .. and I am also swedish .. swedish is

What I said was (The difference is that in my example (second case) do you

truss on chroot .. hmm .. but it run execve .. I don't know exactly what
truss does when it run through the exec but I think it should follow it ..

Well I got a lot there just to test (but I think I have forgotten to
remove those after the testing .. or simply haven't stop testing) ..

Hmm .. then perhaps you miss the most important dl.so ?? (I missed it and
tried for long without it ..) hmm .. it's named ld.so.1 in ~ftp/usr/lib ..
(softlinked to it is ld.so) .. hmm .. well .. I'll need to check later ..
I need to get some programs installed on a mashine that almost doesn't
know it own name (and I still need to show it the network) .. *sigh*

Good luck .. I am here on email length ..

You may be running into the same problem that I have: corrupt NIS info.
Are you running NIS by any chance? I currently have a system that allows
users in the local passwd file to login but refuses users that are in the
NIS files. Telnet works ok for NIS users, but ftp doesn't.

(She's baaack :-) Saw a glimpse of a post saying something about
how it would be nice to have a FAQ for just Solaris - after having been
slightly side-tracked, I'm semi-back with the previously promised
Solaris/wu-ftpd how-to guide. This is the first draft:

http://www.teleport.com/~minerva/wu-ftpd/wuftpd.htm

I still consider it a draft because it doesn't quite cover everything and
is only good for beta-11 and beta-12; the beta-13 version should be out
within two weeks.

If you have comments/suggestions/flames/praises, please send them to:
[email protected] - I'm only skimming the list at this point :-)

I will post another announcement after the next major revision of the
guide.

Thanks to everyone who contributed - if I left anyone out of the
acknowledgments, please drop me a line and I will remedy it as soon as
possible.

Cheers,

This *sounds* like a chroot problem, not a shell problem. My guess is
that you don't have the "ls" command set up correctly in the chroot
environment - a common problem, especially under Solaris. It can be a
little difficult to build an 'ls' program (which is what the "dir" FTP
command runs) that will run under a chroot environment - you need to
build either a statically linked version of "ls" or make sure you have
all the dynamic libraries you need in the chroot /usr/lib directory.

You do not need a real shell to run "dir", just a real, working "ls" in
the chroot area.

Look at the RFC that defines the ftp protocol.

Subject: wu-ftpd on AIX 4.2

Status: OR

I compiled the beta version of wu-ftpd on an AIX v 4.1 server without
any problem. I installed it on an AIX 4.2 server: no problem...

It works for REAL users and the ANONYMOUS user, but not for other
anonymous users ( GUEST users )
If I try to make a GUEST-user I always get the message
'530 access has been denied ...' What can be wrong ?

- Is there a big difference between AIX 3.1 and 3.2 ? or
- Do I have to change some settings in the ftpaccess-file ?

y.s,

Hi,

I have been reading the guest wu.ftp how-to page and following the steps it
says. It was very well explained and I got it set up on my Linux server. The
only problem is I could not delete files. I got the "ls" bit working and I
wonder if I could get some help here to finish the job.

regards,
vincent

Subject: Re: dir command dumps core
X-Sun-Charset: US-ASCII
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Status: OR

I posted a problem last Thursday concerning 'dir' not listing anything
and dumping core under Solaris 2.5. I was using the vanilla 2.4 version
of wu-ftpd.

Thanks especially to Jim Davis for leading me on the right track. You
definitely want the academic version (which I think now is 13; Version
12 was the latest when I went to get it at:

ftp://ftp.academ.com/pub/wu-ftpd/private/wu-ftpd-2.4.2-beta-13.tar.Z

*HOWEVER* it turns out that *ORIGINAL* Sun in.ftpd manual page is the
one that really counts when setting things up. You are told explicitly
what files you need where (especially all the libraries required to
make dynamically linked ls work; some are extra in case you are running
NIS - put them in there anyway, even if you aren't). The wu-ftpd
in.ftpd man page is much more generic in it's approach (understandibly
so).

My suggestion, if I may be so bold, is to change the Makefile so that
when the wu-ftpd version of the page is installed it does not overwrite
the old one AND do it so that it is installed in section 8 instead of
1M - this way you can use the -s flag in the man command to find
whichever page you need.

I would think that this will solve most 2.5.1 problems as well, though
I have yet to try...

Thanks again for all the help. This is a **GREAT** listserver.

Cheers,
-bd

Hi

I have been trying to install wu-ftpd on Irix 5.3 , but I keep getting
errors.

I am using gcc and I have sett the correct paths for this in the
makefiles.

But it says gcc can't exec as: Cannot find file or directory.

I do not know which file it is looking for.

Has anyone installed on IRIX who could help me out

Thanks

X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Status: OR

There is a bug in the modifications made to parsetime() in access.c
in Beta 13, a bracket is in the wrong place causing access limits
involving days other than Any not to be enforced.

The same function is present in ftpcount.c so the original change
plus fix is also appropriate there.

The patch included below fixes the problem (and corrects the formatting).

I have all of the library files listed in the man page there, but dir still
doesn't work. Many of the library pieces are symbolic links. I'm assuming
those should work, though the man page says to copy, which would destroy
the links:

I installed it using cc, however I'm trying it with gcc right now and not
getting any warnings about as. What build are you running, or are you doing
it directly? What compile flags are you using?

It sounded like you tried to manually copy the files. I would make sure
you are using the Solaris Script in the man page. I have attached it
here for your reference. Give it a whirl... (define your anonymous ftp
user in /etc/passwd first!).

The library files that I am using for my 2.5.1 installation are actual 2.5
libs. I upgraded the OS put left the same ~ftp directory. This is the list
of the libraries I am using:

Size File name

106768 Feb 18 00:47 ld.so.1
192328 Feb 17 21:53 libc.a
664048 Feb 17 22:19 libc.so.1
2568 Feb 17 22:19 libdl.so.1
15304 Feb 17 22:19 libintl.so.1
39340 Feb 17 22:19 libw.so.1

The ls binary is also a 2.5 version. I hope this helps with your problem...

<It sounded like you tried to manually copy the files. I would make sure

<user in /etc/passwd first!).

I used a script that basically did the same thing as the script, but there
are some differences in some files that were installed (other than in the
usr/lib area).

As pointed out by another person, the in.ftpd man page is overwritten by
the wu-ftp install. That is a no-no. If anything, the man page should
be installed in /usr/local/man/man8 or /usr/share/man/man8, but not in
/usr/share/man/man1m. So I never saw the script.

Also, the script you included was not from Solaris 2.5.1 and it failed at
the cpio command. The one that comes with Solaris 2.5.1 worked. But, it
led me in the right direction. BTW, the script copies over /etc/passwd and
/etc/group and it really shouldn't. Once the copy of passwd and group have
been done, hand edit the files and just leave the entry for root.

To find out what the differences are between the other install script that
I used and this one, I'd have to compare them and frankly it isn't worth it.

Thanks to all, the problem is now solved.

Maybe this script should be added to the wu-ftpd distribution.

The Solaris install script:

Line wrap problem. The above two lines should be a single line.

Line wrap problem. The above two lines should be a single line. That is
why the cpio command failed, as mentioned in my previous message. Gotta

This hack writthen by Nicolas Pioch been part of the code

???
maybe a little more info on the behaviour you want to add

wu-ftpd is suffering from a major attack of ``creeping featurism''
even after the clean up of *_H, Barber and all the people in this list/net.

It has a straight lineage from the BSD code,
I thought I'd see the end of it with the raise of HTTP
but it seems ageless :-)

I have found how to fix some things in Solaris 2.5.1 and wu-ftpd, but I
still cannot get the following to work with wu-ftpd (beta 11, 12 or 13):

1) messages and banners commands in ftpaccess file
2) guestgroup members are not chroot'ed to their directories
3) ftpwho, ftpcount - always show 0 users, not matter what
4) ftpshut - does absolutely nothing

I have compiled with cc, not gcc (because I couldn't get it installed
correctly - not a programmer, and cc was already installed on one
system) - is this a problem?

If anyone can send me their compiled copy of wu-ftpd (any version) so I
can see if it behaves differently.. I would be extremely grateful!

Thanks,
Mike Farace

Michael,
Can go online to the actual RFC for FTP itself, but I prefer using a book
since the codes are basically static. I use TCP/IP Illustrated, Volume 1 The
Protocols by W. Richard Stevens by Addison-Wesley. It has a chapter
on FTP which discusses the numeric reply codes you described.

I've looked everywhere for a list of the numeric codes that
display during an ftp session, but have not been able to
find such a list anywhere. (550 et al)

Can someone point me in the right direction?

FTP hasn't been replaced by HTTP because FTP clients can do things that
Web browsers can't. Most browsers can't 'put' a file (as far as I
know), and I don't think any of them can do an 'mget' or 'mput'. I
wonder... Have any FTP clients been modified to work with HTTP?

Ftp is alive and well in our department, but the traffic level hasn't
increased recently, while the http traffic keeps zooming up. In fact I'm
delaying installing beta-13 because I'm moving our web server to a bigger
machine today to keep up...

Eventually the various papers and programs our faculty have traditionally
put up for anonymous ftp will migrate to the web server. But I think
that'll take several years, at least. I don't think anonymous ftp servers
will go away anytime soon.

Though as recently as 1995 gopher still seemed to be big, and now...

<I have found how to fix some things in Solaris 2.5.1 and wu-ftpd, but I
<still cannot get the following to work with wu-ftpd (beta 11, 12 or 13):

I am running beta 12 under Solaris 2.5.1.

<1) messages and banners commands in ftpaccess file

That works for me. I have a .welcome.msg file in ~ftp and the following lines
in ftpaccess:

message .welcome.msg login
message .message cwd=*

The .welcome.msg is displayed when the anonymous user logs in.

<2) guestgroup members are not chroot'ed to their directories

Interesting, I have one guest member and it kinda works. Here are the lines
that I have in the listed files:

/etc/group:

guest::5000:ftmsftp

/etc/passwd:

ftmsftp:x:5001:5000:Guest FTP account:/usr/export/ftms_releases/ftp/./ftms:/bin/false

ftpaccess:

class local real,guest *
class remote anonymous *
guestgroup guest

Here is the interesting part. If I log in as ftmsftp, I get to where I am
supposed to go, and that is ~ftp/ftms. BUT, I am allowed to move up a
directory into the parent of ~ftp/ftms. Is this right? I cannot cd out of
the ~ftp area, but I can certainly leave ~ftp/ftms.

<3) ftpwho, ftpcount - always show 0 users, not matter what

Haven't used either, so I don't know.

<4) ftpshut - does absolutely nothing

Haven't used this one either.

<I have compiled with cc, not gcc (because I couldn't get it installed

GCC does take a little patience, but it does compile. It takes three times
for the first time builder of GCC. Once using cc, then once using the just
built GCC and then once more with the newest built GCC. From that point
on, each revision of GCC only requires one pass of the compiler (using GCC).

<If anyone can send me their compiled copy of wu-ftpd (any version) so I
<can see if it behaves differently.. I would be extremely grateful!

My copy is available as:

ftp://ftms.com/pub/misc/in.ftpd.gz

The ftp files it is looking for go in /etc/ftpd

Ian has send in a couple of critical bug reports on the beta-13 which means
that there must be beta-14.

I will also run through the documentation and make some changes in how
manual pages are installed for some platforms (solaris in particular) to
help folks when they have to make chrooted filesystems get it right.

I will release beta-14 as soon as possible, but realisitically, it will
probably be just before the April IETF.

Netscape can 'put', but it's pretty limitted. As for a web client than
can mget, try a bot like wget (very simply unix command line bot.)

The main thing that I miss in http access to files that I find in most ftpd
servers is the -t option to the ls command, i.e. the option to request a
listing of entries sorted by time. That way it is easy to spot what is new. I
know that it might be possible to set up one's httpd server to do this but it
is seldom done.

sunsite.unc.edu has set up parallel http and ftp access to their archive. I
find that I still need to go in with ftp because I cannot get a time sorted
directory listing with http.

SAY WHAT !!!!!!
you had a shell prompt while loggin as "ftp" ?????

Even if your config files are royally screwed you should not be able
to escape from the chroot().

What version are you running ?
Did you compile it, or some unknow bin on the net ?

There are some very nice people on this list, just send

Hello everyone. I would like to know if I can do the following with
wu-ftp:

. I would like to set up an anonymous ftp site (that I know wu-ftp can
do :-)).
. I would like to have a directory that people can upload to, but once
files are uploaded, they can not see them or modify them. This I'm
pretty sure I can do. The FAQ says to set the owner of the directory
to non ftp, turn off read-other in the directory, and I think set the
't' bit to prevent deletes.
. Here is the fun part: I want other anonymous people to be able to
download these files if they know what the file name is. In other
words, they can not see the files with 'ls', but if they type 'get
apple314' then they will get the file 'apple314'.

What we're trying to do is provide an easy way for staff to exchange
files with the outside, but deter the site from becoming a warz site.

Thanks in advance.

My experiance at ftp.cdrom.com (wcarchive) isn't the same. It's been a
continuous struggle to keep up with the increasing demand. We started out
with a anonymous user limit of 150 users back in 1994, and today we often
hit the limit of 1600 users during the peak period of the day. The bits/
second going out has been scaling along with the increased user load, with
the current daytime traffic at around 25Mbps. At the current growth rate of
100% per year, we'll have to support 10,000 simultaneous users by the year
2000...and we'll need something faster than 100Mbit ethernet. The biggest
bottleneck in the growth has consistently been main memory. I've worked
very hard to reduce the memory requirements of ftpd - I've cut it in half,
but even so, we can't increase the current limit beyond 1600 users until we
replace all of the memory (512MB) with higher capacity SIMMs.

That is how it is supposed to work. The "/./" in the home directory path is
interpreted by the ftp daemon as "chroot to here".

The directory listing that is returned is a function of the web server,
not the protocol.

For example, with Apache, you could have a cgi generate the directory
listing, and suppose you click on the "date" title, it could return the
files sorted by date for you.

Directory permissions of 0733, non ftp owned, works well.

Just set upload permissions to 444 in /etc/ftpaccess. The file is
readable even though the directory is not.

I don't think, you should take this for granted.
There is no rules/std on the ouptut of LIST/NLST in any RFC for FTP.

It works because a good majority of ftp will spawn .. popen("/bin/ls")

Actually a good part of ftpds that do not run on Un*x or have a
BUILTIN_LS will just neglect this in the good case scenario or reject
it in the worse case scenario. I've seen some BUILTIN_LS
ftpd respond:
: -t file not found

But we should not worry about this .. Un*x rules ... right ? :-)

We have a 100Mbit ethernet connection to a (fast ethernet) switch that
connects to CRL's core routers, which in turn have DS3 connections to PB-NAP,
MAE-west, MAE-east, and CIX-SMDS. We currently default all the traffic to
a single router which then redirects the traffic to the other routers,
but a plan has been proposed to run gated/BGP and take a full routing
table (about 17,000 routes) so that we can talk to each of the routers
directly.

Just set permissions on the directory that people upload into so that
people do not have read permissions but they do have execute permission.

However, I think your purpose would be better served by having a "public"
account that is allowed to upload into a publicly available directory. You
would give the password to the "public" account to those staff who you wish
to be able to distribute information. Assuming you don't just give each
staff member his own account and allow them to upload onto your ftp site --
the staff are then accountable.

Alternately, the public account can download anonymously uploaded files,
and your staff hands out the password to those with whom they wish to
exchange information. However, this second choice is not as safe.

Correct. It goes there just fine. But chroot means that the location is
supposed to be the "root" of the user, but it isn't. I'm able to cd into
the ~ftp root directory.

The chroot appears not to be working correctly in this case.

<you had a shell prompt while loggin as "ftp" ?????

An update on this problem. It is VERY MISLEADING to test the shell escape
on the same machine that has the ftp daemon. I too freaked when I saw that.
The !sh gives you a shell for the user on the machine doing the calling.
So, do the ftp to the server from a different machine and you will find that
the shell you get is on the machine you are ftping from.

So, all is A-OK with the !sh from the ftp program.

Thanks goodness.

But which system were you on? If you're on a unixboxen, ftp to the
server, and type

!sh

then yes indeed you'll get a shell -- but on unixboxen, not the server.
That's all happening clientside.

Now if that also happens serverside, well then we do have a problem.

Not so. ftpd splits the home directory into 2 parts around the "/./",
chdirs/chroots to the first then chdirs to the second. So when you login
you should be in /usr/export/ftms_releases/ftp/ftms and you should be
able to "cd .." exactly once. Neil.

I needed to shutdown my FTP server here and turn off service to the
virtual servers I manage. I found that shutting down the ftp server
with ftpshut in a virtual setup was kludgey at best.

What I've included in the shar file below is the source to ftpshut
with modification and ftprestart (to allow easy restarting of the server).

ftpshut.c changes
------------------

The copy of ftpshut.c (taken from BETA-13) supports shutting down the
server for both real users as well as guest accounts. It also supports
virtual FTP servers.

Configurations:
- FTPD server setup with no anonymous ftp support and NO virtual servers
setup then the changes to ftpshut have no effect. The shutdown message
file specified in the shutdown directive is created as before.

- FTPD server setup WITH anonymous ftp support and NO virtual servers setup,
ftpshut creates the shutdown message file at the location specified in
the shutdown directive and also creates the message file in the anonymous
FTP area. This allows automated support for both real users and guest
accounts.

- FTPD server setup WITH anonymous ftp support and WITH virtual servers
setup, ftpshut acts as above and additionally creates the shutdown
message file in the virtual FTP directories specified in the ftpaccess
file. This allows shutdown support for virtual servers as well.

ftprestart removes the files put in place by ftpshut.

This is beta software and I'd appreciate any feedback. I am not putting any
copyrights on this software and it can be used as you see fit. Useful here...

X Shutting Down Your FTP server
X =============================
X
In order to support the proper shutting down of your server, you need to
assure that the shutdown message file is in both the real user and anonymous
user ftp areas. The location of the shutdown mesage file is specified in
the ftpaccess file "shutdown" directive.
X
The problem is the supplied utility, 'ftpshut', only creates the message
file in the actual location as indicated in the shutdown directive.
X
In the INSTALL file of wu-ftpd 2.4.* it is recommended to create a link
in order for shutdown to work properly for real and anonymous user, e.g.
If you use 'ftpshut', it will create a message file at the location
specified in the ftpaccess shutdown directive.
X
When you are ready to remove the shutdown message file, you have to do so
manually. (Ever had to go look in the ftpaccess file for its location
because you forgot ...;-))
X
The following changes to 'ftpshut.c' and the new utility 'ftprestart'
implement a means of shutting down the system that makes it convenient for
the admin and does not require that you leave unresovled sybolic links
scattered around your filesystems.
X
There are two files here, ftpshut and ftprestart. The copy of ftpshut.c
included below was originally taken from BETA-13.
X
PLEASE NOTE: In order to get the virtual FTP server support described below
you need to specify -DVIRTUAL in the appropriate makefile for your system.
X
----------------------------------------------------------------------
ftpshut.c changes
------------------
X
The copy of ftpshut.c supports shutting down the server for both
real users as well as guest accounts. It also supports virtual
FTP servers.
X
Configurations:
X - FTPD server setup with no anonymous ftp support and NO virtual servers
X setup then the changes to ftpshut have no effect. The shutdown message
X file specified in the shutdown directive is created as before.
X
X - FTPD server setup WITH anonymous ftp support and NO virtual servers setup,
X ftpshut creates the shutdown message file at the location specified in
X the shutdown directive and also creates the message file in the anonymous
X FTP area. This allows automated support for both real users and guest
X accounts.
X
X - FTPD server setup WITH anonymous ftp support and WITH virtual servers
X setup, ftpshut acts as above and additionally creates the shutdown
X message file in the virtual FTP directories specified in the ftpaccess
X file. This allows shutdown support for virtual servers as well.
X
------------------ Example segment ------------------
shutdown /etc/shutmsg
X
# Virtual Server at 10.10.10.2 (ftp.some.domain)
virtual 10.10.10.2 root /servers/some.domain/ftp
virtual 10.10.10.2 banner /servers/some.domain/ftp/etc/msgs/banner.msg
virtual 10.10.10.2 logfile /var/log/servers/some.domain/xferlog
X
X
# Virtual Server at 10.10.10.10 (ftp.someother.domain)
virtual 10.10.10.10 root /servers/someother.domain/ftp
virtual 10.10.10.10 banner /servers/someother.domain/ftp/etc/msgs/banner.msg
virtual 10.10.10.10 logfile /var/log/servers/someother.domain/xferlog
------------------
X
Shutdown message files are created at
X
X /etc/shutmsg
X /servers/some.domain/ftp/etc/shutmsg
X /servers/someother.domain/ftp/etc/shutmsg
X
Each file contains the same information.
X
----------------------------------------------------------------------
ftprestart.c:
-------------
X
ftprestart is used when you are ready to re-enable your FTP server.
It does the opposite of ftpshut and removes shutdown message files
that were created by ftpshut. It will remove the system-wide shutdown
message file as well as the shutdown message files in the anonymous
ftp areas and any virtual ftp server areas.
X
Sample output:
X ftprestart: /servers/some.domain/ftp/etc/shutmsg removed.
X ftprestart: /servers/someother.domain/ftp/etc/shutmsg removed.
X ftprestart: /etc/shutmsg removed.
X
These modifications are being contributed for potential inclusion in the
wu-ftpd baseline.

Greetings,

I have set this up many times before, but am now getting strange
problem with wu-ftpd 2.4.2b11.

Example --
Name (neptune:hjass):
530 User hjass access denied....
Login failed.
ftp> quit

anonymous access does not work as well.

* the shells are in /etc/shells
* ftpd was compiled on the same system (solaris 2.5.1 + SISS 1.0),
and for other same setups has always worked
* passwords are correct in the /etc/shadow file (as on other servers
where this is running)
* there is no /etc/ftpusers file
* no deny commands in /usr/local/etc/ftpaccess
* has been compiled with shadow support as far as I am aware of (as
working on other exactly same config/OS servers!)

What could the problem be?

Thanks,
Haralds

P.S. Please send replies to me directly ([email protected])

<Now if that also happens serverside, well then we do have a problem.

As pointed out in a previous message, it was not serverside. In my case,
the serverside and unixboxen are one and the same. I suspect that may be
the root of the problem with the original poster.

No, it's not. Remember that shell escapes run on the client's computer,
not the server. When you escape with '!sh', you are running /bin/sh on
your *LOCAL* system, not the server. Try it on a Windows box to prove
my point. On Windows NT, the shell escape is '!cmd', which gives you a
"C" prompt. Exit from that shell, and you are returned to the FTP
client.

If our experience at sunsite is any judge, this type of strategy is a
fairly poor deterrence, since warez doodz generally distribute complete
pathnames when advertising their stuff. However, if you're a low profile
site it's probably not a big deal as long as you keep a close eye on it.

Does anyone know of any problems with the Solaris Recommended patches
causing problems with wu-ftpd maybe?

Are most people who Run Sol 2.5.1 and wu-ftpd, apply the Recommend patch
cluster?

Just wondering if this could be causing problems too...

Thanks,

**NO** Mr Vidiot, you got it all wrong :-(

Sir, We're not talking about the same thing, shell escapes features that
is provided by most ftp clients is allright.

What I was refering to is in some binary version distributed on the net

_PATH_EXECPATH was set to "/bin"

in this case scenario, ... it is .. a problem and a very urging one

Thanks. I found that I had forgotten to do ln -s
/usr/local/etc/ftpaccess ftpaccess in /etc (as now it looks for
ftpaccess there, while by default I place in /usr/local/etc)!

I second this :-)
I would advise the
SITE GROUP, SITE GPASS approach
it is more suitable for this type of cooperative exchange

applied...no problems with wu-ftpd.

of the patches patched over your copy of wu-ftpd?

We installed most of the recommended patches (all of the TCP/IP related
ones) and we still have problems with hanging ftpds with beta12.

Well I do not know for sure about 2.5.1 but, I did install the
recommend patches for Sol 2.5 x86 from
ftp://sunsolve1.Sun.COM/pub/patches/patches.html
about two weeks ago and my beta 12 is running fine. We are a pretty
busy site with 6-7000 downloads a day so I think it is safe to say it
has been tested out here and is ok.

You are correct in that how I thought it would work, doesn't. In my case
it doesn't matter if the user can cd up one directory and move around the
~ftp tree.

This is something I'm trying to track down, but can't put my
finger on... Hagngin ftpds...

Having a cronjob that goes on a killing spree every now and then
is tempting but doesn't resolve the real of the problem.

At first I thougth it was the locking accouting mechanism(and endless loop
'til the process got the lock) but after modification of the code, things
didn't improve that much.

The problem did not go away with the beta versions.

If anyone can give me more input on this,

I appreciate

It appears to me to come from timeouts when uploading. Those are the only
stuck daemons I see. (linux 2.0.27). It is especially prone to happen
when coming across the Internet at busy times.

The main hang problem is probably occuring on uploads. I don't believe
that keepalives are enabled, so if the connectivity goes away with the remote
host at the 'right' time, the server kernel won't be expecting any more data
and the connection will just sit idle. If you enable keepalives, then the
connection should eventually time out, but this could take awhile (the
keepalive timeout period is 2 hours). A better solution is to set an alarm
prior to beginning the data transfer (either upload or download) - similar
to what is done in early in the main command loop for idle sessions.

Hi all,

First, I'll introduce myself. I'm Ariel Orellana, I'm the network
administrator. 24 years old. I think that cavers the basics.

Now, on to the question... just installed wu-ftpd 2.4 on a HP-UX 10.01 system.

I'm having trouble granting access to hosts that are not on my /etc/hosts file.
We haven't configured DNS - yet (it's a private network). Maybe a month or so.
Meanwhile, how can I grant access to everyone without having to add any and all
hosts to my file?

In case it's necessary, my ftpaccess file looks something like this:

class all anonymous,guest,real *
..
..

If you got a shell prompt from !sh then you should have gotten a 'local'
shell prompt, not a remote shell.

I was having all kinds of problems with chroot with beta 11 and 12, but
thanks to someone else I rechecked my inetd.conf and found out a slight
typo was causing the -a flag to never be sent to ftpd, thus my ftpaccess
file was not being read and with beta 11/12 changing the default
behaviour it wasnt being read at all.

Once I fixed that, my chroot worked again. :)

Hallo!

I just have installed the wu-ftpd-2.4 on one of my AIX-machines and now I
tried to connect to this host with ftp, but it failes.
The user I have tested with ist in the /etc/passwd and hasn't got a
null-password und the user doesn't appear in the /etc/ftpusers.
But I don't have a command named "getusershell". Could this be my
problem, or what else? Can anybody help me?

Thanks

AIX uses ksh which isn't one of those (/bin/sh, /bin/csh) hard coded into
wu-ftpd. I must confess I (against advice) hard coded ksh into
getusershell.c along with the others. I had to severely munge the code to
get it to compile on AIX anyway- this was just one more thing ;)
(wu-ftpd-2.4 'stock' version).

The right way to do it is to create a file /etc/shells and add each valid
shell to it.

In my opinion, that's very much the WRONG way to do it..... nothing
else in AIX understands /etc/shells, so you'll now be maintaining the
list of valid shells in two places (the real AIX place
/etc/security/login.cfg and /etc/shells).

I've got a patch to wu-ftpd that makes it get the valid shells the
"AIX way" at tigger.itc.virginia.edu:/pub/AIX/wu-ftpd.diffs.txt.gz

I was wondering if anyone has any experience with logging sub-logins under WU-FTP.
Our user "ftp" gets everything logged just fine, but the sub-login "my-sub-login"
I created doesn't get logged. I tried making /bin/false a script that sends, basically:

/usr/ucb/ls -lt | /usr/ucb/mail -s "sub-login was here" [email protected]

this didn't work. For some reason I'm just not seeing how to tie this in to the
WU-FTP? I can handle a RTFM, but please tell me which FM. Is this mechanism explained
in Managing_Internet_Services, or in the WU-FTP manual pages?

I am have created and admin user for the ftp server's partition. It
allows this admin user to have full access to this ftp partition to
manage it. This user also needs to add new users for ftp access.

Apparently if I add them to group 14 (sysadmin), they can then do it
from the admintool. But I need a command line option, so they can run
/usr/sbin/useradd - which only is allowed to be run by root.

Anyone have any other ideas? I have heard of utililities that can give
limited root functions to a user... does anyone have one, or know if
that would even work?

Thanks,

I am having a similar problem. Mine will not chroot, and depending on who owns the tree that I
want to access, it may not even access.
I am trying to create logins that can ONLY ftp and not telnet. I also do not want these users
wandering around and seeing what other similar users have got.
I added guestgroup ftpart to ftpaccess file
I created a user called dell
I created in /home/artdept/dell (The home dir) a bin and etc dir.
dell is member or group ftpart
dell's shell is /bin/false
the passwd entry has /home/artdept/dell/./incoming in the home dir field
Dells home tree is owned by dell.artdept
when I ftp in as dell, I find myself in the home dir as opposed to the ~dell/incoming dir and I
can cd all the way to root (The REAL ROOT)
Any ideas... Running on Linux 2.0.0 with BETA12

Even though I found the place that sub-login logging is *supposed* to be done from,
(../../../ftpaccess) it doesn't work. This is what I have:

log commands real,anonymous,sub-login
log transfer anonymous,real,sub-login inbound,outbound

(note: name of customer changed to "sub-login" here)

Now I have a few questions about this. In the book Managing Internet Information
Services it uses the words "log transfer" in our file it said "log transfers".
Would that cause it to not work either way?

Perhaps I'm just having trouble getting the proper daemon to reread the config files.

Since /usr/local/etc/ftpd is controlled by /etc/inetd.conf I do a kill -1 on inetd, which
seems to have no effect at the time, but later on I see the changes (I ran ftp with the
-a and -d options, after an unknown while these took effect (but not right away). there
is no /../../../ftpd running all the time. We would prefer not to just reboot everytime
the files change.

ftpd does _not_ run all the time. It is only invoked when an ftp connection
is initiated (send/receive). You might want to make sure that there are
no active ftp connections before you give your -1 (Hangup=HUP) signal to
inted.

Also, the last three fields in FTPCONVERSIONS confuses me, what are

sudo sounds like what you need. You could even set sudo to only let that
admin add users with useradd -g ftpadmin ...

The latest sudo may always be gotten via anonymous ftp
from ftp.courtesan.com in the directory /pub/sudo/.

Hi,

I just joined this group because I have a problem setting up this daemon...
I'd like to look in the FAQ first. Is there any?

Is there a way under wu-ftpd (or any other unix ftpd for that matter) to
restrict the bandwidth used by each connection? (Or perhaps even all
connections put together.)

I have a Redhat Linux 3.0.3 distribution (Picasso - Kernel 1.2.13). I
downloaded wu-ftpd 2.4 and did the gunzip and tar just fine. I put the
wu-ftpd in the following directory: /usr/src/wu-ftpd-2.4 I went to do
the the 'build' from this directory: build lnx . Unfortunately, I got
the following error: "Cannot open lnx.s." I am stumped. Can someone
help me. The FAQ doesn't mention anything about this type of problem. I
feel like I'm in a race, and I can't even get out of the starting
blocks? Thanks!

I think the people at cistron.nl have hacked this into the ftpd they run.

The fixes referenced in the wu-ftpd FAQ (#7 and #8) don't seem to
work for IRIX.

Thanks...

In support/makefiles/Makefile.aix, see this section:

authuser.c strdup.c snprintf.c
OBJS = getusershell.o fnmatch.o strcasestr.o strsep.o \
authuser.o strdup.o snprintf.c

In OBJS, you want to change from snprintf.c to snprintf.o.

I'm guessing this is the result of some late night slaving over the
code. ;-)

Already submitted this to [email protected], although I'm pretty
sure someone else's already noticed this by now.

Otherwise, it compiles cleanly on an AIX 4.1.4 system using IBM's C compiler.

Hi,

thanks to everybody how showed me were the FAQ is!

Unfortunately the FAQ did not help me... so:

I am having trouble with the automatic compression/decompression:

I always get file not found errors!
This is for real users and anon-ftp!

SunOS 4.1.4
(Version wu-2.4(1))
ckconfig says everything is ok. (I did not change the default paths)

wu-ftpd itself is working (dir, ls, get...)
chroot ~ftp /bin/compress something works too (so all libraries/devices are
there)

contents of ftpacces: (as in doc/examples)

I guess I am missing something... But what?

Change SPT_TYPE in your config file to SPT_NONE. SPT_REUSEARGV is not
applicable to IRIX unfortunately.

Well, besides the name of the file being a problem.... ;-)

Have you checked the permissions on the ~ftp/bin directory and
executables and make sure they are inplace and executable by your
ftp user ?

You probably want to get RedHat 4.1 for starters:

ftp://sunsite.unc.edu/pub/Linux/distributions/redhat/redhat-4.1/i386

They distribute a copy of wuftpd in rpm format - it's in fact a package
option when you install. Last I recall it's beta12, but they're pretty
good about getting new RPMs built quickly.

We're having a serious problem with the wu-ftpd server... at least it
appears to be wu-ftpd. If I run any version greater than beta-11, we
start getting reports of users who are unable to connect from a web
browser. I checked with our networks department and we have both PASV and
ACTIVE port enabled.

Does this problem ring a bell? Any assistance would be appreciated.

I'd been wondering why I hadn't come across this on my server (Solaris 2.5,
wustl 2.4)... This would explain it, since we get very few uploads (I put
most of the data we make available under the root area myself, using cp/rcp.)

Thanks to all for helping clear this up...

I'm not sure if they've released the patches. You might poke around the
site and see if you can find them.

Edwin,

I see you got no replies to your question...probably because you're

using AIX, just like me. I'm not sure what your question is. Are
you
trying to limit a guest account to a chrooted environment?

[email protected] at EXTERNAL Date: 3/4/97 3:57 AM

I compiled the beta version of wu-ftpd on an AIX v 4.1 server
without
any problem. I installed it on an AIX 4.2 server: no problem...

It works for REAL users and the ANONYMOUS user, but not for other
anonymous users ( GUEST users )
If I try to make a GUEST-user I always get the message
'530 access has been denied ...' What can be wrong ?

- Is there a big difference between AIX 3.1 and 3.2 ? or
- Do I have to change some settings in the ftpaccess-file ?

y.s,

E.Stornebrink

Subject: Problem with anonumous guest users
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

I've got the following problem with WU-FTPD 2.4:
================================================

If I ftp and log in as an anonymous guest user, the server initially
says:

"Your current dir. is "/"".

But if I do 'cd /' my current dir. will become the root of the server
and not the root of the chrooted environment !

How is this possible ?

I made an anonymous guest user in WU-FTPD 2.4 ( beta 12 AIX 4.x ) and
set up the following:

> a root directory ( /home/guests ) to 'chroot' to,
which looks like this:

/home/guests/
bin/ls
etc/group
/passwd
lib/libc.a
/libcurses.a

> a guest user in /etc/passwd, which looks like:

guest1:*:401:400:Guest FTP
user:/home/guests/./guest1:/etc/ftponly

> a group ftpguests (gid 400) in the /etc/group file
> also the same entries in the group and passwd in /home/guests/etc
> In the ftpaccess file I made an entry : guestgroup ftpguests
> For ftpgroups and ftphosts I used the example files

Hallo Edwin!

Where is your directory /etc/ftponly? I think you have to create it
relativ to the chrooted environment. Therefore create a directory
/home/guests/etc/ftponly.

Edwin, see that /etc/ftponly is registered in /etc/shells.

The ftp program tries to verify the shell you're using so
that a user couldn't fake any other programs into it. If
the entry is not there, the shell validation will fail and
the directory default to /.

Regards,

Oliver

Hi!

I use WU-FTP 2.4 to Sun Solaris 2.4. I have a problem.
The process of FTP never die. The line in inetd that
call ftp daemon is:

ftp stream tcp nowait root
/etc/ftpd/ftpd /etc/ftpd/ftpd -adl

Is this correct? Thank's in advance!

I checked. compress has the same permissions as ls and ls works...

Michael,
In running the 2.4 generic version I run wuftpd with -l -L. We do a
lot of uploads compared to downloads and I end up seeing about 2-3
new processes hanging each day. Right now a lot of uploads is only 50
or so per day, but we might only do 3-4 downloads.

Hi Edwin,

I had a similar problem with a real user account. I looked at similar
real users and there was no difference anywhere in the setup or config
files. In the end the solution was permissions getting to the directory
of the user. The permissions on a directory folder 2 layers up from
the users' account were incorrect. Check the permissions on all the
folders in the path going to that user or users.

Hope this helps.

We're still seeing hanging ftpd processes on sunsite, solaris 2.5.1, and
they don't seem to be related to uploads. Trussing a typical hung process
(hanging for 2 days now) reveals:

# truss -p 12781
write(12, " ^FD077F f10DCD3 \ QBEE9".., 16384) (sleeping...)

The stack is:

# /usr/proc/bin/pstack 12781
12781: in.ftpd -a
df6795f4 write (c, 5f248, 4000)
df6795f4 _libc_write (c, 5f248, 4000, df678840, 0, 3ec70) + 8

000146c8 main (38c00, dfffff24, dfffff38, 3de2c, 1, 0) + 964
00013ce8 _start (0, 0, 0, 0, 0, 0) + 5c

and the file descriptor to which it's writing is:

# /usr/proc/bin/pfiles 12781
12781: in.ftpd -a
...
12: S_IFCHR mode:0000 dev:109,8 ino:9464 uid:0 gid:0 rdev:42,34959
O_RDWR

The process is attached to 204.17.119.64:

# /usr/ucb/ps -uwwwwww 12781
USER PID %CPU %MEM SZ RSS TT S START TIME COMMAND
ftp 12781 0.0 0.2 1716 1172 ? S Mar 04 0:00 ftpd:
204.17.119.64: anonymous/mozilla@: RETR

And netstat reveals the socket is in CLOSE_WAIT:
# netstat -n -f inet | grep 204.17.119.64
152.2.254.81.21 204.17.119.64.4442 8192 0 10122 0
CLOSE_WAIT
152.2.254.81.56495 204.17.119.64.4443 1 0 10122 0
CLOSE_WAIT

Obviously this is not hanging on upload since it's hung trying to write to
is a tcp stream, not a file. Anyone have any clues on this?

Seems to me I recall there were a flurry of patches to the Academ releases
to correct various hung ftpd's and add timeouts to sections of the code.

I recall that problems were associated with cases where the user did not
disconnect the session gracefully.

I bet that it does not matter, if a function was started, then the
user session abnormally terminated (link outage, ect..) then it would hang.

You'd need a setuid root adduser tool, or a setuid-root wrapper for an
adduser tool.
For a simple (but probably not very secure) way, ask root to create a
setuid root shellscript like this:

#!/bin/sh
/sbin/useradd -m -s /dev/null -g ftponly -d /ftp/user/$1 $1
^^^^^^^^^ ^^^^^^^ ^^^^^^^^^^
Shell group homedir. base

Then call the script with the username as parameter whenever you want to
create a new user.

Is anyone running wu-ftpd-2.4 on Unixware 1.1.x?
If so could you mail me the config file and any hints for the
Makefile.
I have successfully compiled it without regex support, and it will run
but not support any ~/bin exec things - even ls. And yes I have done
the shared lib things. The machine was already doing ftp with the
standard in.ftpd and the /var/ftp/ directory tree.

Any help greatly appreciated.

This is probably caused by a bug in the Solaris TCP/IP implementation.
There are a few timer/timeout related bugs in the BSD networking code (which
Solaris uses) that I fixed in FreeBSD about a year ago:

RCS file: /home/ncvs/src/sys/netinet/tcp_timer.c,v
..
----------------------------
revision 1.16
date: 1996/04/15 03:46:33; author: davidg; state: Exp; lines: +2 -2
Two fixes from Rich Stevens:

1) Set the persist timer to help time-out connections in the CLOSING state.
2) Honor the keep-alive timer in the CLOSING state.

This fixes problems with connections getting "stuck" due to incompletion
of the final connection shutdown which can be a BIG problem on busy WWW
servers.
----------------------------
..
revision 1.8
date: 1995/07/29 18:48:43; author: davidg; state: Exp; lines: +17 -1
Add connection drop capability for persist timeouts.

Reviewed by: Andras Olah
Obtained from: 4.4BSD-lite2 via W. Richard Stevens
----------------------------

The hang that you're seeing is likely caused by the bug fixed in rev 1.8
above. The comment that was added in 1.8 explains further:

+ /*
+ * Hack: if the peer is dead/unreachable, we do not
+ * time out if the window is closed. After a full
+ * backoff, drop the connection if the idle time
+ * (no responses to probes) reaches the maximum
+ * backoff that we would use if retransmitting.

Chris,
Thanks for responding, but there is no SPT_TYPE in any config.h file
nor is it referenced in any of the software in my wu-ftpd-2.4 release.

I did try adding the SPT_NONE definition to the config.h and it didn't
solve the problem. It records syslog entries in Greenwich Mean Time,
which is +5 hours from all other syslog entries.

If you have encountered this problem on IRIX 5.3 OR IRIX 6.2 and
resolved it, please let me know how you did it. Was it wu-ftpd-2.4
or some earlier release?

Thanks...

Hello, folks!

I know this is a FAQ - but I have looked at the official FAQ, and
those solutions didn't fix me. I'll try to provide helpful details,
and perhaps they will remind someone of a similar scenario.

I'm trying to set up an *intranet* ftp server on a SunOS 4.1.3 box,
and have mostly succeeded. However, I cannot log in as myself! And
as I am the testcase for 'real' users generally, I fear this bodes not
well for they who yet shall follow.

Here's how it looks:

Connected to 148.57.5.101.
220 ftp-hal FTP server (Version wu-2.4(3) Thu Feb 27 22:24:12 PST 1997) ready.
Name (148.57.5.101:bobh): bobh
530 User bobh access denied.
Login failed.
Remote system type is UNIX.
Using binary mode to transfer files.

Relevant lines from ftpaccess:

class all real,guest *
limit all 5 Any /etc/msgs/msg.toomany

I have a normal passwd entry in etc/passwd, my (NFS-mounted) home
directory is visible on the server system, and anonymous logins
succeed every time. My shell is in etc/shells, and here's the
significant line from /etc/inetd.conf:

ftp stream tcp nowait root /usr/local/etc/ftpd ftpd -a

Anybody see a flaw here? I don't quite understand where I've gone
wrong.

Thanks!

For Irix, you should use a beta release of wu-ftpd (beta-12 is what I
prefer) since somewhere during beta they fixed the hanging process problem
with wu-ftpd on IRIX and Solaris. It may be that SPT_TYPE was a config
which was added during this period too, but I'm not sure about that.

Jerry,
In the config file if you undef the SETPROC something or other that
should do it. Irix 6.? doesn't give the right timezone of the
variable is defined.

This was true, until I renamed my ftphosts file. Then it worked.
With that clue, I started messing around with my entry in ftphosts,
and it turned out to be the fully-qualified host.domainname. When I
had ".hal.com" on the end of the hostname, it failed. When I took it
off, it worked. Go figure!

It seems one the reason for the servers hang is when
the clients do not issue the FIN.

UPLOAD
The client/server setup the connection(PORT or PASV),
but something went havoc. The server waits for hours,
days, month (the read() never returns).
David GreenMan proposed the use of keepalive timer option.

LOCKING
Endless loops in acl_countusers(), acl_join(), acl_remove().
This is easily detected; syslog is clobber with:

..sleeping: fcntl lock of pid file failed:

I've put a limited number of iterations before harakiri
The side effects is _PATH_PIDNAMES may be corrupted.
(more input needed)

PASV(web browsers ??)
Client does the PASV, RETR sequence and goes havoc.
A timer with select()(provided by C. Dick ? not sure)
Also Michael Brennen(?) had a patch a timer around accept().
I think it is include in beta-1{2,3}.

So probably setting the keepalive option when opening a socket
can be an insteresting workd around.

Other ideas ?

The matching(fnmatch()) failed surely for a good reason.
check your syslog for something like this
syslog(LOG_NOTICE,
"FTP LOGIN REFUSED (name in %s) FROM %s [%s], %s",
_PATH_FTPHOSTS, remotehost, remoteaddr, name);

and see why
remotehost != "*.hal.com"

you may doing multihoming and have different PTR records, in that case you
should had them all in ftphosts.

How about instead of setting an alarm(0) (clearing the alarm) when exiting
the command loop to process a command, set a larger alarm time like 24 hours?
This alarm would limit the maximum amount of time that any one file transfer
can take, but would still allow the ftp session to last more than a day in
total.

There are a number of bugs in the Sun bugs database about problems with
things hanging in a CLOSE_WAIT state:

1259260 TCP connections get stuck in CLOSE_WAIT state forever
1188068 TCP connections remaining in CLOSE_WAIT indefinitely
1242876 TCP port hangs in CLOSE_WAIT or BOUND state and had to reboot.
1166730 Connections stay in CLOSE_WAIT state for ever
1220193 large number of connections in CLOSE_WAIT

Curiously all these bug reports have a 'closed' state, but there is no
corresponding patch id. Or workaround listed.

None mention (wu-)ftpd explicitly, but they all seem to involve clients
connecting to servers and then suddenly going away.

Incidently, the promising-sounding ndd variable 'tcp_close_wait_interval'
doesn't have anything to do with the CLOSE_WAIT state. (It's how long a
connection stays in the TIME_WAIT state.)

yes I see what you mean, but wu-ftpd for example version 13
use the alarm(in dataconn()), without carring if it was set before.

This is ok, because like you pointed out the alarm(timeout)
is reset every time reentering the command loop.
But it would make it hard to implement a global timer, well,
at least the use of alarm() should be done with care.

I wasn't thinking of using SOL_KEEPALIVE on the controlling socket
but only when doing transferts. So doing a setsockopt() in dataconn()
and probably getdatasock() should be enough.

#include <disclaimer.h> /* :-) */

Althought the use of KEEPALIVE is controversial. it seems justified in
this scenario.

Now that said :-), I probably need to do more tests
and back this with some facts.

Or rather make it configurable (from the ftpaccess file) to whatever
is suitable for the site.

Looks like you have an older release. Maybe SETPROCTITLE is set in
this release.
Undefine this and your time should be right.
reason: SETPROCTITLE removes removes the environment (including $TZ)

We have a working wuftpd on our AIXs since 3 month.

Recently, we decided to use the logging feature to see what our users are
doing. So we changed in inetd.conf the command for ftpd from ftp -a to ftp
-l -a.

When we refreshed inetd. We could no longer log in. ftpd seemed to be
inexistent: when we issued ftp comand in any client, ps -ef in the server
gived no process ftpd launched.

When we looked in the log, there was :

Mar 7 14:34:36 internet2 inetd[23718]: inetd: 0826-512 ftp/tcp: System
call bind failed. This name of socket is already chosen. (approximatly
translated from french)

And we can not restart the server because it's a production machine.

Any ideas ?

Thank you in advance

Hello,

I'm new to this list, so i don't know, if this problem was discussed
earlier here.

Recently i have installed wu-ftpd-2.4.2-beta-12. Everything seems to work
fine, until I have tried to login under real user name from outside of our
subnet. I was getting message "user <real_user_name> access denied".
However, anonymous login were allowed.

Background: Sun Ultra Enterprise 4000/ Solaris 2.5.1. Also, we are using
some kind of tcpd wrappers.

Any help would be greatly appreciated.

I'd be _most_ unhappy about this, unless it is an option which can be set via
the ftpaccess file, and the duration could be specified or set to "no time
out" (set the duration to 0 ?).

I have had genuine transfers from my server which have taken longer than
24 hours to complete. If a user waits a long time for a large file to
transfer, only for it to fail before completion due to a 24 hour timeout,
they aren't going to be best pleased...

Cheers, Bob

Ok, got a question for y'all because I can't decide if this is a bug, an
implementation issue, or a protocol issue:

user on box A is ftp'ing a file from box A to box B.

ftp> put /etc/services

It should get box A's /etc/services, and deposit on box B as 'services'
in the current directory there, right? Or does the fully qualified path
indicate the files goes into /etc/services on box B?

This is a linux server (kernel 2.0.27, libc 5.3.12) running wu-ftpd 2.4.2
beta 13.

What happens is that there is a STOR /etc/services on box B, which fails
(naturally), which isn't quite what was wanted. ;-)

I don't know if the user command above (put /etc/services) is supposed to
put file in /etc/services on box B *OR* in current dir as 'services' on box B.

If it's the former behavior, then chalk it up to me for not understanding.
If it's the latter, then I'd debug the path info being passed because I also
saw a mention of 553 can't get cwdir directory in a similar test, and
produce a patch as well as filing an official bug report.

Nothing funky for server setup - account isn't chrooted or anything.

If user does this:

ftp> lcd /etc
ftp> put services

Then it deposits file as 'services' in curr. dir. on box B, as expected.

this is more a client issue, then a Protocol issue

put/get etc .. doesn't exist as directives, they are 'std' command
supplied by the client

for example if you use ncftp ftp client
and do

ncftp> put /etc/services

this will be map to:
PORT a,b,c,d,p1,p2
STOR services

ncftp will chop every thing 'til the last '/'

if you try the same thing on a Sun machine with the system ftp

ftp> put /etc/services

you'll have:
PORT a,b,c,d,p1,p2
STOR /etc/services

and the usual answer
553 /etc/services: Permission denied.

put/get are nice commands because you can specify the name of the
remote file so:

ftp> put /etc/services /tmp/boo_c_est_moi

the same for get

If this is a 'normal' situation for that site, though, they would take
steps to make sure downloads from them would be allowed sufficent time to
complete. Our site, anything over an hour or two is almost guarenteed to
be 'lost.'

This is nothing to do with the ftpd server; it sees a "STOR <filename>"
command and tries to carry it out.

The problem is that FTP clients differ; some clients will send a
"STOR /etc/services" command in the situation you describe, while others
may strip off the directory portion and just send "STOR services".

So the difference is down to the client end of the transaction, which is
not something the server can control.

Cheers, Bob

Exactly. Which is why I wouldn't want any specific value hard-coded into
the source. If the timeout value could be switched on/off and set via
the ftpaccess file, then each site could "take steps" appropriate to them,
by setting a suitable value. This is much better than having to recompile
every time you want to change the value.

In our case, I'd not want it enabled at all. Even if it takes 24+ hours to
send 400 Mbytes of data to some of our international sites via ftp, it's still
a lot faster (and much less customs hassle) than trying to mail it. :-)

Cheers, Bob

Just a reminder:
Timeout is configurable on the command line "-t"

It is also configurable by the client

site idle new_timeout
or
quote site idle new_timeout

the timeout that is implemented now is only enable when doing
command parsing. It's disable when doing transfert.
i.e transfert can take an hour, a day, a month, ... a year..
it doesn't matter to TCP, if the two machines are not rebooted
the connection will stay, it doesn't matter if the world came
crumbling down in between.

I do understand your arguments,
the default timeout now is 15 mins and it's possible for the client
to renable it up to 2 hours.

But what kind of numbers to have when doing transfert({up,down}load) ???
2 hours, a day, a week ??

no easy answers.

Below is a perl 5 script I've been using to kill old ftpd
processes. I was written for HP/UX 10.20 and is likely full of OS- and
site-specific code.

It makes a detailed attempt to compute elapsed time from the ps output, to
distingush anonymous from real users, to distingush idle vs. active
sessions, and applies different time limits to accordingly. It reports by
mail when it kills a process.

Huristics are used that can sometimes fail.

Okay... I've prepared a test version of the throttler. It's currently
running as my ftp server at siggy.iceonline.com, but for anonymous access,
it's packed. Because the server is so packed, I'll attatch the diffs here
as text... This is a patch of wu-ftpd-2.4.2-beta-12, which I've dubbed
beta-12.2 (perhaps innapropriately.) The files listed below can be
found at:

ftp://siggy.iceonline.com/pub/other/wu-ftpd-2.4.2-beta-12.2.diff.tar.gz

If you can get on...

Chris...

Notes:
- throttle() currently only supports 1 second grainyness. In my opinion
(partly because I run a site with multi-meg files) this is good enough.
If it isn't, I can put in microsecond grainyness, with little difficulty.
It *will* take more cpu time though.

- In order for anything to happen, THROTTLE must be defined in or around
the config.h file.

- In the ftp access file, a bandwidth directive must be supplied for each
class, or that class has unlimitted bandwidth. Also, a negative bandwidth
is treated as unlimitted. A bandwidth of 0 will result in an actual
bandwidth of 1.

bandwidth <class> <bytes/second>

- Actual bandwidth for a user is total_bandwidth/number_of_users_connected.

- This differs from cistron's server in certain ways. I wrote this with
the idea that it would be easier to incorperate if it caused as few changes
to files outside the new one (throttle.c). This makes it *slightly* less
effecient than theirs, but not much.

- throttle.c includes a large section of #if 0 code which I wrote and think
is more efficient than the access.c counterpart, but I left it out.

I may not be up to speed yet... ie someone may have already found this,
But in my version of WU-FTPD (2.4) There appears to be a bug when using
STOR.

When using STOR, not append and using REST the file is aways trucated.

Subject: Sizing a file.
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Status: OR

I just hav managed to retreive 2.4.2-13 I see, rest is fixed on that so ignore
my previous message.

I was wondering how to use rest when putting ascii files, because files
can change size, I see wuftp copes with that fact an lies about the file size.

However, to do this it scans the complete file, I wondered if this could
lead to a nifty denial of service hack. Ie. I find so very large file, such as
ls-lR.Z then repeated size it in ascii mode, this would result in large
ammounts of cpu being used.

Thoughts?

Hi folks,

I hope that somebody can help me out here, because I'm really
getting mad ......

I have a wu-ftpd-2.4 running on Solaris 2.4. I have a guest group
set up with chroot-ed accounts, this all works fine. Now I would
like to start using ftpconvesions (compress, gzip, tar, just the
simple things). The relevant ftpaccess lines are:

class local real,guest,anonymous <file>
class remote guest,anonymous <file> (file contains '*')
guestgroup guest (this is not the real groupname ;-) )
compress yes local,remote
tar yes local,remote
gzip yes local,remote
log commands guest,real,anonymous
log transfers guest,real,anonymous inbound, outbound

Test 'group' account in /etc/passwd looks like:
test:x:<uid>:<gid>:Test FTP Guest
user:/<home-dir>/./data:/bin/sh

Test 'group' account's bin, lib and dev directories look like:

bin:
---x--x--x 24 root other 14696 Jan 9 1996 compress
---x--x--x 24 root other 72668 Jan 9 1996 gzip
---x--x--x 24 root other 20040 Oct 5 1995 ls

the ftpconversion file looks like:

The server is started with options "-a -l".

Whenever I try to get a compressed file by adding the extention
".Z" or ".gz" I get the error:
550 <file>.Z: No such file OR directory.

Even when I start the server with the "-d" flag, I can't see it even
trying to compress the file !!!!!

HELP ME OUT PLEASE, WHAT AM I DOING WRONG ?!?!?!?!?!

Any help will be greatly appreciated.....

PS.: I have looked in the FAQ but could not find any hints there !

Thanks for any help in advance,

The configuration directive I'd like to see is bandwidth limits on
files/directory trees. Don't know how feasible this is, but I thought I'd
ask for it.

bandwidth path <path> <bytes> <seconds>

<path> relative to ftp root
<bytes> bytes can be transferred every <seconds> seconds.

So,

bandwidth path /pub/sleeze 5000000 3600

would allow (anonymous ftp -- as the path supplied is relative to anonymous
ftp root) to transfer ~5MB from the sleeze directory tree per hour.

Murky implimentation suggestion:

The implementation could keep track of the number of bytes transferred
during the 16 preceeding <seconds>/16 time intervals, and use the sum of
these/<seconds> to compute actual bandwidth. (Implimentation could
actually keep a running sum in each "timebucket".) Every <seconds>/16
interval, it would clear out the oldest "timebucket" and reuse it for the
newest. Clear like mud? The idea is to have a bandwidth resolution of
<seconds>/16. This would keep you from using up all the bandwidth for the
hour in the first minute of the hour. The bandwidth used could then set an
actual bytes/second limit to try to even out the usage during the
"timebucket" -- keeping you from using up all the bandwidth for the
"timebucket" at the beginning of the timebucket.

This is an intersting suggestion. It would not currently be possible, but
when I originally wrote the throttle (hack job that it is) I had another
idea, a bandwidth resource server in mind. With that I'm pretty sure that
I could restrict in the way you suggest. Only problem is that that would
require quite a bit of new code that affects wu-ftpd elsewhere, and I'm not
on the developement 'team'...

Any comments on this, anyone?

<snip>

So,

bandwidth <class> <bytes/second>

restricts members of <class> to those periods when the servers bandwidth is
below <bytes/second>, right? When the overall server bandwidth goes above
<bytes/second>, the bandwidth of members of <class> goes to zero?

I have installed wu-ftpd-2.4.2-beta-12 on Solaris2.3. For the
ftp/anonymous ftp, it seems to work okay. However, for other users,
they will be able to change to root directory just by "cd /". Could
somebody please let me know how I will be able restrict the cd access.

How is enforcement to be done? Deny the transfer?

What about existing tranfers for that class? Will it throttle to
zero and then users connections timeout? Should a minimum and maximum
apply in for existing transfers to allow them to continue.

This is the location for the latest wu-ftpd. You can't see the
directory contents, but get the file anyway. It's there.

Janet,
Take a look at the FAQ and try using guest groups (guest accounts get
chroot'd to their home directory)

I am hoping we might try something else instead in the future.
I wrote a modification in which I check a folder exactly like ftpusers
except it is groups restricted to their own folder.

Then instead of chroot (which requires a bin directory for every user and
therefore if you have a lot of users a lot of overhead), i simply check
in the cwd routine if they are in a restricted group and their cd takes
them out of their directory path i cwd back to their directory.

Some processing overhead, but i have well over a thousand accounts that
all have a restricted shell for telnet, and i needed them restricted for ftp.
It does allow them to cd down in their directory, just not out of it. I
also do a realpath() so symlinks don't work.

Hello All

SunOS newchrono 5.5.1 Generic_103640-04 sun4m sparc SUNW,SPARCstation-10

I have set up wu-ftpd-2.4.2-beta-12 to run chrooted under tcp wrappers.

I am going to have a couple of users maintaining the product accounts
on the ftp server once I finish setting it up. They will need to be
able to change the account passwords. As I have set them up to use
site group and gpass to access product subdirectories they will also
need to be able to change the group passwords.

The problem is this, Solaris 2.5.1 makes no provision I can find for
changing the password in any file other than /etc/shadow. That means
changing the passwords in my /public/etc/shadow and my
/public/etc/group files is a problem. Has anybody else solved this
one?

I would GREATLY prefer not to have users cutting and pasting passwords
into those files. :(

Thanks All
Steve Lee

I posted the following messages to a couple of the solaris newsgroups,
requesting recommendations for any comercial ftp packages for solaris.
I got this great response about a company that does comercial support
for wu-ftpd! If you can't get your problems resolved any other way
(like me!), this may be an option for you.

I think wu-ftpd is great, but I need a bit more help for some reason,
and I personally am going to try this out! You get a pre-compiled
wu-ftpd binary, in standard a standard unix package format (pkgadd), for
$25!.. Support is extra, but very reasonable, at least to me!

FYI - for anyone that is desperate like me!

Hi

Why not use wu-ftp and buy the support?
We do that :-), even that we are in Holland we do supoort severals site
in USA.
We even have a pacthed wu-ftp with extra security feature. We are
connected
to the NET via our own link so live support can be done if needed.
Let me know if interrested.

NB: I need to know the platforms and OS version.

Hi,

I posted the following message to weeks ago but can't get any
response because our mailer doesn't work last week or noone answered
..

Help!
Last week I installed wu-ftpd.2.4 on a sun with OS5.4. All things
work fine but if the logged in anonymous tries to make a ls there is
an error:
Can't create data socket (0.0.0.0,20): Bad file number

I have installed wu-ftpd according to the installation instructions
and the references in the FAQ: extra directories for sun etc ....

I'm a novice in UNIX, so I can't compile a static linked ls.
Who can tell me where I can get a ready one for my system.
and who can tell me exactly how to install this ls for my sunos5.4

Which files and directories do I need for the dynamically linked ls ?

Thanks

chroot(), in spite of all the desavantages, provides a layer of security
.. a jail.. (or an illusion of jail, if we look at the history of
security holes in ftpd :-)

I can see a lot of race conditions in this approach, remember
David Greenman advisory ... If I nag the server for ex: with
cd /very/long/pathname, and send a SIGURG(OOB), I'll be out of jail
an do anything I please under "/", or until the next cd.

> Some processing overhead, but i have well over a thousand accounts that

why chdir() them back **after**
why not just prepend the restricted_path to path
and let chdir() do the rest. This way it will restrict the flip floping
with chdir().

cwd(char *path)
{
....
/*code to check if they're restricted */
...
snprintf(cdpath, sizeof cdpath, "%s/%s", restricted_root, path)
if (chdir(cdpath) >= 0) {
/* send a complaint */
....
}

....
}

> It does allow them to cd down in their directory, just not out of it. I

>

but how do you cope with the rest of the commands ??

You work so far is on cwd() and you maintain a simile jail
without chrooting. But what about the rest of commands ?

get ../../restricted_file
put ../../restricted_file
or
del ../../../file
or
site exec command ../../../../file

etc ...

Nevertheless the idea of maintaining a 'false jail' (with a few processing
overhead) to not use chroot() is very interesting an woth exploring.
If you code is not restricted, why don't you send it, maybe it will
be usefull to someone.

you're problem goes beyond ls setup
you can't create the data channel so
get/put etc ... will not work either

wait I think ... "Paradise Cowgirl" (Don't be full by the name :-)
have done some work on this :

http://www.teleport.com/~minerva/wu-ftpd/wuftpd.htm

Is ~ftp nfs mounted ?
if yes then
you need to create /dev/ticlts the lock daemon needs it

Mrs Darci, if you reading this, /dev/ticlts is missing from your notes
(wait let me Cc)

also
man ftpd
is excellent place to start

A cute wy to work it all out is to use ldd

ldd /bin/ls

That will tell you want libraries are need, NOTE these CANNOT be symbolic links
as they will not work after chroot. you must copy them.

The files I use with wuftpd and sunos (4.1.3)

/bin

---x--x--x 1 root 24576 Sep 22 1994 compress*
---x--x--x 1 root 65536 Sep 22 1994 gzip*
---x--x--x 1 root 13352 Sep 22 1994 ls*
---x--x--x 1 root 131072 Sep 22 1994 tar*

/dev
crw-r--r-- 1 root local 3, 12 Feb 6 1996 zero

don't forget to use mknod to create this...

/etc

-r--r--r-- 1 root 74 Feb 6 1996 group
-r--r--r-- 1 root 49 Sep 22 1994 passwd

Remove the real password and lots of the users from the passwd file...

/usr/lib

-r-xr-xr-x 1 root 40960 Sep 22 1994 ld.so*
-rw-r--r-- 1 root 7996 Feb 6 1996 libc.sa.1.9

-rwxr-xr-x 1 root 24576 Sep 22 1994 libdl.so.1.0*

For solaris 2 (2.4 x86 anyway)

/bin

---x--x--x 1 root ftp 12768 Dec 17 1995 compress*

simlink lib to usr/lib

/etc

You sure your ftpconversions is in the right place?

if you are in any doubt...

strings ftpd | grep ftpconversions

where ftpd is the what ever file your ftpd is stored under it could be

in.ftpd for example.

Make sure you are reading the ORIGINAL Solaris man page for in.ftpd, NOT

I am at internet world this week but next week i will make available my
code / suggestions for alternate handling instead of chroot.

I obviously need to read the rfc's regarding ftp and see the interactions
with all of the commands.

My solution is currently a quick fix but perhaps with others knowledge a
fix for it's pproblems could be attempted.

Subject: changing group passwords
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

Hello again everybody.

I did not get any takers on the last one so how about if I rephrase:

SunOS newchrono 5.5.1 Generic_103640-04 sun4m sparc SUNW,SPARCstation-10
wu-ftpd-2.4.2-beta-12 running chrooted under tcpwrappers.

Anybody know a way of changing group passwords other than cut and paste?

Thanks

I vaguely remember your mail, let see people can
change gid by doing site group/site gpass. Meaning
you have a _PATH_PRIVATE (say "/etc/ftpgroups")

/etc/ftpgroups:
group:passwd:real_group

and you want to change the second field of this file ?

is that right ?

Content-Type: TEXT/PLAIN; charset=US-ASCII

Status: OR

Hello, I'm a newly empowered temporary sys admin (ie the real one quit...)

My ftpaccess file has the following classes and limits defined:

class local real,guest,anonymous *.myhost.foo 0.0.0.0
class remote real,guest,anonymous *

limit local 100 Any /etc/msgs/msg.toomany
limit remote 200 SaSu|Any1800-0600 /etc/msgs/msg.toomany
limit remote 200 Any /etc/msgs/msg.toomany

To me, this is saying that anyone who makes an ftp connection to my site
is considered a member of the local class, be they of the real, guest or
anonymous usertype.

I'm no expert, but from what I understand about groups, this doesn't make
any sense.

Even though the first limit line for class local is set for 100,
can 300 real users connect to me since the limit line just below
for the remote class (which has the same users) is set for 200? (despite
the fact I suspect that no one can come in as remote due to the *
at the end of the remote clas definition line...)

Or does that mean only 100 people can access my archive at a time,
no matter what their user type is? (real, guest or anon)

I'm thinking that I should make the entry more like:

class local real
class guests guest
class anonymouses anonymous

in order to make more connections available for all user types. (?)

Any advice you could give me is appreciated in advance!

You have to make the user a member of guestgroup.

hello all,

I am running Version wu-2.4(1) on Digital OSF V3.2 148.

The %F macro does not seem to work in messages. I show that it should be
replaced by the number of kilobytes free in the current working directory
but it seems to get replaced by "You" instead. The other macros seem to work
just fine.

Thanks in advance!

I have just installed wu-2.4 and am having a small problem. Everything works fine except what I am trying to do. I am trying to make it so that when someone uploads a file (users, not anonymous), the file permissions are set to 644. Is there anyway to do this? I saw that it can be changed for uploads to the ./incoming directory. But I wanted to set it so that if one of my users uploads to his directory, it will auto set the file to 644.

Thanks
Steve

Read the in.ftpd manual page that came **with Solaris 2.5**
not the one that wuftpd installs. If the installation has written
over the original, I will be glad to forward an original to you.
The manual page tells you about additional libraries and devices
you need to add/create (more than there were in SunOS 4.x).

Cheers,

The first line states that any computers in your DNS domain are to be
considered as local hosts. The second line states that any other
computers are to be considered remote. The "class" lines are compared in
sequential order until one is matched.

> limit local 100 Any /etc/msgs/msg.toomany
> limit remote 200 SaSu|Any1800-0600 /etc/msgs/msg.toomany
> limit remote 200 Any /etc/msgs/msg.toomany

The first line limits "local" users; those in your DNS domain (see class
"local" above); to 100 concurrent connections. The second and third
lines apply to "remote" users. Weekends and nights up to 200 can connect
and any other time up to 200 hundred can connect.

The fact that both remote restrictions are set to be 200 is probably a
typo. The third limit line would normally be set to a lower number to
cover weekday accesses than the second line which covers nights and
weekends.

I just experienced the same problem on Solaris 2.3.

The solution was to make all of the files in ~ftp/usr/lib EXECUTABLE.
I don't know why these need to executable but that solved the problem.

On my Linux box, the files are not executable and it works so this must
be Solaris specific.

Read the original Sun in.ftpd man page. It has a script for installing
the necessary files for ftp. It worked for me.

I guess that you will need to ask you to send it to me (please). I read thru the one that came with Solaris 2.5 and the one that came with wuftpd and neither one said a thing about it.

Thanks

Ok, I will send two files as attachments; let me know if you cannot
save them as manual pages.

The first file is 'ftpd.1m' and is a short one that refers to the
second file, 'in.ftpd.1n; which is the actual manual page. Both of
these belong in:

/usr/share/man/man1m

Let me know how it goes.

B in.ftpd
is the Internet File Transfer Protocol (\c
SM FTP\c
) server process.
The server is invoked by the Internet daemon
BR inetd (1M)
each time a connection to the
SM FTP
service (see
BR services (4))
is made.
SH OPTIONS
TP 12

Each
SM FTP
session is logged to the system log daemon
BR syslogd (1M).
TP
BI \-t timeout
Set the inactivity timeout period to
IR timeout seconds.
The
SM FTP
server will timeout an inactive session after 15 minutes.
SS Requests
LP
The
SM FTP
server currently supports the following
SM FTP
requests;
case is not distinguished.

LP
The remaining
SM FTP
requests specified in
SM RFC
959 are recognized, but not implemented.
LP
The
SM FTP
server will abort an active file transfer only when the
SB ABOR
command is preceded by a Telnet \*(lqInterrupt Process\*(rq (IP)
signal and a Telnet \*(lqSynch\*(rq signal in the command Telnet stream,
as described in
SM RFC
959.
LP
B in.ftpd
interprets file names according to the \*(lqglobbing\*(rq
conventions used by
BR sh (1).
This allows users to utilize the metacharacters:
\f3* ? [ ] { } ~\f1
LP
B in.ftpd
authenticates users according to four rules.
RS 6
TP 6
1)
The user name must be in the password data base,
BR /etc/passwd ,
and have a password that is not null. A password
must always be provided by the client before any file operations
may be performed.
TP
2)
If the user name appears in the file
BR /etc/ftpusers ,
B ftp
access is denied.
br
ne 5
TP
3)
B ftp
access is denied if the user's shell (from
BR /etc/passwd )
is not listed in the file
BR /etc/shells.
If the file
BR /etc/shells
does not exist, then the user's shell must be one of the following:
sp 1n
RS 12
TS
tab(:);
lb1 lb1 lb1.
/usr/bin/sh:/usr/bin/csh:/usr/bin/ksh
/usr/bin/jsh:/bin/sh:/bin/csh
/bin/ksh:/bin/jsh:/sbin/sh
/sbin/jsh
TE
RE
sp 1n
TP
4)
If the user name is \*(lqanonymous\*(rq or \*(lqftp\*(rq,
an entry for the user name \f2ftp\f1 must be present in the
password and shadow files.
The user is then allowed
to log in by specifying any password \(em by convention this
is given as the user's e-mail address (such as
BR [email protected] ).
Do not specify a valid shell in the password entry of the
\f2ftp\f1 user, and do not give it a valid password (use NP in the
encrypted password field of the shadow file).
RE
LP
For anonymous ftp users,
B in.ftpd
takes special measures to restrict the client's access privileges.
The server performs a

command to the home directory of the \*(lqftp\*(rq user.
In order that system security is not breached, it is recommended
that the \*(lqftp\*(rq subtree be constructed with care; the following
rules are suggested.
sp 1n
TP 12
B ~ftp
Make the home directory owned by
B root
and unwritable by anyone. This directory should not be on a file
system mounted with the
B nosuid
option.

TP
B ~ftp/bin
Make this directory owned by the super-user and unwritable by
anyone. Make this a symbolic link to
B ~ftp/usr/bin
The program
BR ls (1)
must be present to support the list commands. This
program should have mode 111.
br

TP
B ~ftp/usr/lib
Make this directory owned by the super-user and unwritable by
anyone.
Copy the following shared libraries from
B /usr/lib
into this directory.:

BR netconfig (4)
must be present for the
BR ls (1)
command to work properly. These files should be mode 444.
TP
B ~ftp/pub
Make this directory mode 777 and owned by
BR ftp .
Users should then place files which are to be accessible via the
anonymous account in this directory.
TP
B ~ftp/dev
Make this directory owned by the super-user and unwritable
by anyone. First perform
B ls \-lL
on the device files listed below to determine their major and minor

SH EXAMPLES
LP
To set up anonymous ftp, add the following entry to the
B /etc/passwd
file. In this case,
B /export/ftp
was chosen to be the anonymous ftp
area, and the shell is the non-existent file
BR /nosuchshell .
This prevents users from logging in as the ftp user.
in +4n
B ftp:x:30000:30000:Anonymous FTP:/export/ftp:/nosuchshell

SH NOTES
The anonymous account is inherently dangerous
and should be avoided when possible.
LP
The server must run as the super-user to
create sockets with privileged
port numbers. It maintains an effective
user id of the logged in user,
reverting to the super-user only when binding
addresses to sockets.
The possible security holes have been
extensively scrutinized, but are
possibly incomplete.

I hope that someone can help me with this one. I have ftp up and running and my other problems fixed thanks to a couple of people from the list. Now my problem is this. I have several virtual domains on my server and some of them want their own ftp areas so that when you anonymous ftp to the site mydomain.com (the virtual domain), you won't get the main servers anonymous ftp area. I hope that makes since. If anybody has done this, please let me know how. I haven't found any documentation on it and if there is some, I would be happy if someone could point me to it. I am using wu-ftpd2.4

Thanks

Hi Chris

Do you know where I can get a already built copy of wu-ftpd2.4....
for IRIX6.2.

The problem I am having is that I do not have a C compiler, I could use
gnu, but I have been told that gnu will not work without some libraries
or something (I am not good in C).

Any Ideas..

Thanks Iqbal

Draft FAQ: Supporting Virtual Servers in WU-FTPD:

------------------------------
Subject: 1. Introduction

So you want to setup virtual FTP servers using the same system...
What follows are instructions for doing so. These are not meant to
hold your hand but they are meant to make setting it up just a bit
easier.

------------------------------

Subject: 2. What is virtual FTP server support ?

If you need to manage an ftp server for two separate domains,
you need to be able to support virtual FTP servers. Basically,
this allows an administrator to configure their system so a user
ftping to ftp1.domain.com gets one ftp banner and one ftp directory
and a user ftping to ftp2.domain.com gets another banner and directory
even though they are on the same machine and use the same ports.

------------------------------

Subject: 3. Configuring IP Address Aliases

You have to be able to setup alias IP addresses in order for this
to work. Linux and BSDI, SGI, Solaris 2.5* and other support this.
Check your documentation for ifconfig for your specific systems.

For example, on Sun Solaris 2.5* systems you will need to do something
like the following.

A. Assure/place the system's normal hostname/IP address in
the file /etc/hostname.le0.

B. Insert the following in the system initialization file
/etc/init.d/rootuser just after the if/fi test for
interface_names.

#
# configure virtual host interfaces quietly.
#
/sbin/ifconfig le0:1 inet XXX.XXX.XXX.XXX netmask + broadcast + \
-trailers up 2>&1 > /dev/null

Replace XXX.XXX.XXX.XXX with the IP address that you wish to
alias.

C. Reboot your system. Yes, you can do it by hand but you are
going to have to test it after a reboot anyway so why wait ?

[ NOTE: I'd like to put in other systems info here ]
[ if people would be kind enough to send them to me. ]

------------------------------

Subject: 4. Setting up the directory structure for virtual server support

You will need to setup a separate directory structure for each
virtual server that you plan on installing. There are various
scripts available to assist you. Best to grab one and customize
it for your environment so it's easier next time. Oh... there
won't be a next time ? Then do it by hand making sure all the
standard support directories are there (bin/etc/dev/usr/..).

------------------------------

Subject: 5. Building the software

In order to get the virtual support compiled in you will need to
add -DVIRTUAL to the CFLAGS of the appropriate Makefile.

Step 1: If you are adding this to a fresh copy of the server, just
untarred, without ever having built the software edit the
file in src/makefiles that matches target platform you will
use in "build"ing it.

(i.e. Solaris2.x edit src/makefiles/Makefile.sol).

If you have previously built the server then the appropriate
makefile has been linked into the "src" directory and all you
need to do is edit src/Makefile, add -DVIRTUAL to CFLAGS and
then type "build clean"

Step 2: Follow the documented build and install procedures.

------------------------------

Subject: 6. ftpaccess file Modifications

You need to specify three separate things for each virtual server
you setup.

1. "root" - This it the path to the ftp directory that you
previously setup for this virtual server.

2. "banner" - This it the path to banner you wish displayed
when a user connects to the virtual server.

3. "logfile" - This is the path to the logfile that is setup
specifically for this virtual server.

The format of a virtual server entry is

virtual <address> <root|banner|logfile> <path>

<address> is the ip address of the virtual server. The second argument
specifies the <path> is either the path to the root of the filesystem
for this virtual server, the banner presented to the user when connecting
to this virtual server, or the logfile where transfers are recorded for
this virtual server. If the logfile is not specified the default logfile
will be used.

For example, add lines similar to the following for each virtual server
you are trying to set up.

# Virtual Server at 10.10.10.10
virtual 10.10.10.10 root /var/ftp/virtual/ftp-serv
virtual 10.10.10.10 banner /var/ftp/virtual/ftp-serv/banner.msg
virtual 10.10.10.10 logfile /var/log/ftp/virtual/ftp-serv/xferlog

All other message files and permissions as well as any other settings
in the ftpaccess file apply to all virtual servers.

NOTE: Your operating system may not support the virtual server feature.
It has been tested on BSD/OS, Solaris 2.X and Linux.

------------------------------

Subject: 7. Supporting virtual logging.

There are two different types of logging, the standard syslog logging
and transfer logging. In order to separate transfer (or xferlog)
logging it is necessary to use the virtual "logfile" entry as described
above.

To enable logging via syslog, follow the standard syslog configuration
instructions found in your system's documentation. If you have syslog
logging enabled you will see entries such as

Mar 3 15:26:30 rkive ftpd[27207]: VirtualFTP Connect to: xxx.xxx.xxx.xxx

This will enable you to determine which virtual server the logs
pertain to.

------------------------------

Subject: 8. Setting up other support files

The message files need to be inside the anonymous ftp hierarchy so
that they can be used after the chroot to the virtual server's ftp
directory. (deny, welcome, etc.)

You need to customize the banners and welcome messages...

------------------------------

Subject: 9. ftpaccess access information that should be supported but isn't

It would be useful to have the "email" directive supported. Then you
would be able to specify %E in the banner and welcome message files.
Today it is not supported and there is only one email directive allowed.

The "guestserver" directive is not documented in the manpage. It would
useful to be able to use that in a virtual setup.

------------------------------

Subject: 10. Shutting down your virtual FTP servers

At the present time use the ftpshut/ftprestart programs I put
together. They should appear in the baselined code in the future.

You can grab a copy from

In order to support the proper shutting down of your server, you need to
assure that the shutdown message file is in both the real user and
anonymous user ftp areas. The location of the shutdown mesage file is
specified in the ftpaccess file "shutdown" directive.

The changes to 'ftpshut.c' and the new utility 'ftprestart' implement a
means of shutting down the system that makes it convenient for the admin
and does not require that you leave unresovled sybolic links scattered
around your filesystems.

ftpshut.c changes
------------------

The copy of ftpshut.c supports shutting down the server for both
real users as well as guest accounts. It also supports virtual
FTP servers.

Configurations:
- FTPD server setup with no anonymous ftp support and NO virtual servers
setup then the changes to ftpshut have no effect. The shutdown message
file specified in the shutdown directive is created as before.

- FTPD server setup WITH anonymous ftp support and NO virtual servers
setup, ftpshut creates the shutdown message file at the location
specified in the shutdown directive and also creates the message file
in the anonymous FTP area. This allows automated support for both real
users and guest accounts.

- FTPD server setup WITH anonymous ftp support and WITH virtual servers
setup, ftpshut acts as above and additionally creates the shutdown
message file in the virtual FTP directories specified in the ftpaccess
file. This allows shutdown support for virtual servers as well.

------------------ Example segment ------------------
shutdown /etc/shutmsg

# Virtual Server at 10.10.10.2 (ftp.some.domain)
virtual 10.10.10.2 root /servers/some.domain/ftp
virtual 10.10.10.2 banner /servers/some.domain/ftp/etc/msgs/banner.msg
virtual 10.10.10.2 logfile /var/log/servers/some.domain/xferlog

# Virtual Server at 10.10.10.10 (ftp.someother.domain)
virtual 10.10.10.10 root /servers/someother.domain/ftp
virtual 10.10.10.10 banner /servers/someother.domain/ftp/etc/msgs/banner.msg
virtual 10.10.10.10 logfile /var/log/servers/someother.domain/xferlog
------------------

Shutdown message files are created at

/etc/shutmsg
/servers/some.domain/ftp/etc/shutmsg
/servers/someother.domain/ftp/etc/shutmsg

------------------------------

Subject: 11. Restarting your shutdown virtual FTP servers

ftprestart is used when you are ready to re-enable your FTP server.
It does the opposite of ftpshut and removes shutdown message files
that were created by ftpshut. It will remove the system-wide shutdown
message file as well as the shutdown message files in the anonymous
ftp areas and any virtual ftp server areas.

Sample output:
ftprestart: /servers/some.domain/ftp/etc/shutmsg removed.
ftprestart: /servers/someother.domain/ftp/etc/shutmsg removed.
ftprestart: /etc/shutmsg removed.

Academ version of wu-ftpd 2.4 Release 2 Beta 10 on. I do not warrant
the descriptions and instructions in this document. Use it AT YOUR OWN

Configuring IP Aliases on SGI:

1. Login as root
2. edit /etc/hosts to include IP address and the name of the virtual server
3. edit /etc/config/ipaliases.options using comments in that file as a
template:

ec0 192.111.26.51 netmask 0xffffff00 broadcast 192.111.26.255

or

ec0 foobar netmask 0xffffff00 broadcast 192.111.26.255

4. /etc/chkconfig -f ipaliases on
5. reboot

6. use netstat or ping to check if it is running.

I've a way you can use virtual ftp and support the

e-mail directive

upload directive (very useful for setting ownership and permissions)

& probably guestserver (I'm not familar with that one) and lots of other
directives too, (different classes, etc., I'm using the e-mail and upload
directives on my virtual ftp servers.)

Instructions (a little loose for an exact step by step, but it's a start):

Read all of these instructions before starting.

Get the ftpaccess patch from
ftp://ftp.meme.com/pub/software/wu-ftpd-2.4.2/. It's there as a tar file,
a gzipped tar file, a rpm file, and just a directory with the patch and a
README. (I haven't tried this patch with beta 12 or beta 13, it works on
beta 11. Contact me if you have any problems in later releases and I'll
fix it.) Read the README and put the patch in with patch.

Recompile and re-install wu-ftpd.

You now have a ftpd that will take an argument to -a, the path to the
ftpaccess file.

Get a copy of tcpwrappers (one can be found at
ftp://coast.cs.purdue.edu/pub/tools/unix/tcp_wrappers. I'd like to know
the offical distribution point, but haven't taken the time to find it. If
you know, drop me a note.). (Every system providing services to the net
should have a copy of this anyhow.) Read the directions. Compile it with
full options so the TWIST command will work. Install it. (If you're using
Redhat Linux, it comes with tcpwrappers ready to go.)

Configure your virtual servers: Make /etc/ftpaccess a directory, put
different ftpaccess files into it, using file names of your choosing.
Remove the virtual directives and anything else needed by the virtual
servers from the old /etc/ftpaccess file and move it into /etc/ftpaccess.
Each virtual server can have it's own ftpaccess file, or they can share.
The different ftpaccess files can contain completly different sets of
directives as each configuration file can configure a single virtual
server. The ftpaccess file of a virtual server dosen't need to have any
configuration directives not used by that virtual server, so it dosen't
need virtual commands for any of the other virtual servers and it dosen't
need class directives or whatnot used only by the regular ftp server.

Use tcpwrappers to give ftpd a different command line for each virtual
server, directing each virtual server to the appropritate ftpaccess file:

Modify /etc/inetd.conf to invoke tcpwrapper. On my system the new line for
the ftp port looks like:

ftp stream tcp nowait root /usr/sbin/tcpd /usr/local/sbin/ftpd

Add a line to /etc/hosts.allow for the real ftp server and for each virtual
ftp server. Use the -a option to tell ftpd which ftpaccess file to use for
each server. On my system a typical line looks like:

[email protected] : ALL : twist exec /usr/local/sbin/ftpd -l -a
/etc/ftpacces
s/x.meme.com

Note that the ip number is the ip number used by the ftp server, the same
as that in the ftpaccess virtual directive.

Note: with an "ftproot" directive to tell the ftp server a path to use as
root for anonymous ftp access, the virtual directives become completely
unnecessary. This would be handy because it would reduce the spattering of
ip numbers about the system (and simplfy the ftpd code.)

As for guestserver:

>From ftpd.c source:
/*
** Algorithm used:
** - if no "guestserver" directive is present, -- Sergei Rousakov,
** anonymous access is allowed, for backward compatibility.
** - if a "guestserver" directive is present,
** anonymous access is restricted to the machines listed,
** usually the machine whose CNAME on the current domain
** is "ftp"...
**
** the format of the "guestserver" line is
** guestserver [<machine1> [<machineN>]]

I copyed all the libraries to /usr/lib then symlinked /usr/lib /lib just to be
safe.

Ps: As to the person who could not get wuftpd to work on solaris 2.4 question
has been answered already this month, its in the mail archives. I guess we
need someone to write a step by step faq.

Pps: have you changed your inetd.conf, have you created the ftp user and have
you installed the appropriate /etc files?

I saw your posting to Chris and I know what it's like trying to get
executables for IRIX.
Here are the one's I've been using for a couple of months. They work
except for the time (it shows GMT). I've been too busy to recompile.
When I do I'll drop you a line (if you like).

ftp://ftp.tmsdesign.com/private/irixwu.tar.gz

Good Luck,
karl

After much struggle I got the ls to work by statically recompiling
the ls command but now I can't seem to get in. I was able to
get in one time but now I have no ftpaccess file to disallow
any users for testing and I have tried "kill -HUP pid of inetd"
to restart it but it just won't let anyone in.

It's normal. The code deals with this problem by sleeping. You may want to
mask it out of your log files with a filter though.

I wouldn't not say normal if you have _a lot_ of this from the same process
It's probably 'stuck', you'll have to kill the process by hand.

> The code deals with this problem by sleeping.

IMHO deals with it the wrong way

> You may want to mask it out of your log files with a filter though.

it also a good sign that something is wrong i.e too many connections
NFS going bezerk .. what ever. In breif once a while is fine but
clobbering syslog is worth investigating.

I've had the same problem, It's not something to be ignored.
The ftp service locks up and no-one is able to ftp in.
The only way I can get it to stop is to kil the active ftp processes
and kill -HUP the init daemon.
Has anyone found a work around ???

it's not exactly a work around, I've change the code
to allow a fix number of iterations, about 300 secs which
is infinity to any normal human :-) then give up and bail out.
_PATHPIDNAMES may be in a funny state .i.e wrong count

About 150 an hour, from lots of different processes, not the same one over
and over. Typically we handle 150,000 transactions per day, so only a
small fraction of the ftpds run into this problem. Just curious, it
doesn't seem to be harming anything.

It would certainly be nice if the [email protected]
alias would work for this as well. It seems liek all the rest of
the lists I'm on work this way.

create a /etc/ftpaccess file or, run in.ftpd without the -a option
in your inetd.conf

Subject: Solaris 2.X installation guide for wu-ftpd 2.4.2
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Status: OR

Many people have asked how to install wuftpd on solaris 2.X systems, this is
a step by setup guide. Some of issues may vary between solaris 2 version, if
your solaris 2 version has slight differences please mail me them, I have
assumed a minium level of knowledge, such as being able to ftp file, and
extract tar files, and know how to use an editor.

This guide has no warranty, it may not be correct for your system, it could
even damage it, use at your own risk.

Written by James Hawtin

email: [email protected]

So far this guide has been tested on,

solaris 2.4 X86

This guide is divided into a number of sections.

1) compiliation and installation
2) setting up anonymous ftp
3) where to go from here.

1.1) what version of wuftpd do you have?

Is your version older than 2.4.2-beta13, if so get a new copy this guide is
designed to work with 2.4.2-beta13

The latest version is

ftp://ftp.academ.com/pub/wu-ftpd/private/wu-ftpd-2.4.2-beta-13.tar.Z

1.2)

Extract the tar file, and type.

cp /usr/share/man/man1m/in.ftpd.1m ~

This file contains alot of useful help in setting up an ftparchive

build sol
su -
<your root password>
cd <where ever your source directory is>
build install
cd /usr/man
catman -M . -w

1.3)

check your inetd.conf

in should contain the following line, if it contains a different one replace
it.

ftp stream tcp nowait root /usr/sbin/in.ftpd in.ftpd -a
^^ ^^ ^^ ^^ ^^ ^^
^^ These gaps are tabs not spaces.

The -a option is to use the access file. READ THE MAN PAGE ON ftpaccess.

kill -HUP <the process id of inetd>

1.4)

setup the appropriate /etc files,

/etc/ftpusers

The users not permitted to ftp as.

My list contains

-----snip----
root
daemon
bin
sys
adm
lp
smtp
uucp
nuucp
listen
nobody
noaccess
init
-----snip----

/etc/shells

Valid shells for users

My list contains

-----snip----
/usr/bin/sh
/usr/bin/csh
/usr/bin/ksh
/usr/bin/jsh
/bin/sh
/bin/csh
/bin/ksh
/bin/jsh
/sbin/sh
/sbin/jsh
/oolon/local/bin/tcsh
/oolon/local/bin/bash
-----snip----

see the wuftpd documation about these, to get things working just touch the
files, to start with.

/etc/ftpgroups
/etc/ftpaccess
/etc/ftpconversions
/etc/ftphosts

2) setting up anonymous ftp

we are going to setup an anonymous ftp service, using the path /oolon/ftp
to contain the files.

2.1) setup an ftp user

edit /etc/group
add

ftp::<what ever group number you want>:
In my example.
-----snip----
ftp::2010:
-----snip----

edit /etc/passwd

ftp:x:<what ever uid you want>:<your ftp group>:FTP Daemon:/oolon/ftp:/bin/true
in my example
-----snip----
ftp:x:2001:2010:FTP Daemon:/oolon/ftp:/bin/true
-----snip----

edit /etc/shadow
add the line
-----snip----
ftp:*LK*:8668::::::
-----snip----

Ok, now it is impossible to login as the ftp user....

2.2) populating your ftp archive.

mkdir /oolon/ftp
mkdir /oolon/ftp/bin
mkdir /oolon/ftp/dev
mkdir /oolon/ftp/etc
mkdir /oolon/ftp/pub
mkdir /oolon/ftp/usr
mkdir /oolon/ftp/usr/bin
mkdir /oolon/ftp/usr/lib
(in you want uploads)
mkdir /oolon/ftp/pub/incoming
cd /oolon/ftp
ln -s usr/lib lib
ln -s usr/bin bin

2.3) copying in important files

cd usr/bin
cp /usr/bin/ls /usr/bin/compress /usr/bin/tar .
you may also wish to copy gzip in there.

chmod 111 ls compress tar gzip

cd ../usr/lib

PLEASE NOTE YOUR VERSION NUMBERS OF THESE FILES MAY DIFFER

cp /usr/lib/ld.so.1 .
cp /usr/lib/libc.so.1 .
cp /usr/lib/libdl.so.1 .
cp /usr/lib/libintl.so.1 .
cp /usr/lib/libnsl.so.1 .
cp /usr/lib/libsocket.so.1 .
cp /usr/lib/libw.so.1 .
cp /usr/lib/nss_dns.so.1 .
cp /usr/lib/nss_files.so.1 .
cp /usr/lib/nss_nis.so.1 .
cp /usr/lib/nss_nisplus.so.1 .
cp /usr/lib/straddr.so.2 .

chmod 555 *

ln -s ld.so.1 ld.so
ln -s libc.so.1 libc.so
ln -s libdl.so.1 libdl.so
ln -s libintl.so.1 libintl.so
ln -s libnsl.so.1 libnsl.so
ln -s libsocket.so.1 libsocket.so
ln -s libw.so.1 libw.so
ln -s nss_dns.so.1 nss_dns.so
ln -s nss_files.so.1 nss_files.so
ln -s nss_nis.so.1 nss_nis.so
ln -s nss_nisplus.so.1 nss_nisplus.so
ln -s straddr.so.2 straddr.so

cd ../../etc

cp /etc/netconfig .

create a group file with

-----snip----
root::0:
ftp::<ftp group>:
-----snip----

create a passwd file with

-----snip----
root:x:0:0::/:/
ftp:x:<ftp uid>:<ftp group>::/:/
-----snip----

chmod 444 passwd netconfig group

2.4) Now the difficult bit making the devices

ls -alLF /dev/tcp /dev/udp /dev/ticotsord /dev/zero

This will be in the format.

crw-rw-rw- 1 root sys 11, 42 Nov 9 1995 /dev/tcp
crw-rw-rw- 1 root sys 99, 1 Nov 9 1995 /dev/ticotsord
crw-rw-rw- 1 root sys 11, 41 Aug 4 1994 /dev/udp
crw-rw-rw- 1 root sys 13, 12 Aug 4 1994 /dev/zero

This is of the format <major> <minor> for example tcp has a major of 11 and
a minor of 42

cd ../dev

We need to mknod each of the files.

mknod <name> c <major> <minor>

So in my example we need to

mknod tcp c 11 42
mknod ticotsord c 99 11
mknod udp c 11 41
mknod zero c 13 12

chmod 444 zero
chmod 644 tcp udp ticotsord

chown root zero tcp udp ticotsord
chgrp sys zero tcp udp ticotsord

2.5) setting up safer access permissions

chmod 555 usr/lib usr/bin usr etc dev
chmod 755 pub

touch .notar
touch pub/.notar

(in you want uploads)

chmod 777 pub/incoming

2.5) I want to tar, and gz files automagically.
Make sure you have copyed gzip into usr/bin

create a /etc/ftpconversions containing

-----snip----
:.Z: : :/bin/compress -d -c %s:T_REG|T_ASCII:O_UNCOMPRESS:UNCOMPRESS
: : :.Z:/bin/compress -c %s:T_REG:O_COMPRESS:COMPRESS
:.gz: : :/bin/gzip -cd %s:T_REG|T_ASCII:O_UNCOMPRESS:GUNZIP
: : :.gz:/bin/gzip -c %s:T_REG:O_COMPRESS:GZIP
: : :.tar:/bin/tar -cf - %s:T_REG|T_DIR:O_TAR:TAR
: : :.tar.Z:/bin/tar -cZf - %s:T_REG|T_DIR:O_COMPRESS|O_TAR:TAR+COMPRESS
: : :.tar.gz:/bin/tar -czf - %s:T_REG|T_DIR:O_COMPRESS|O_TAR:TAR+GZIP
-----snip----

make sure your /etc/ftpaccess has something like the following in it.

-----snip----
class all real,guest,anonymous *

limit all 10 Any /etc/msgs/msg.dead

readme README* login
readme README* cwd=*

message /welcome.msg login
message .message cwd=*

compress yes local remote
tar yes local remote

log commands real
log transfers anonymous,real inbound,outbound

shutdown /etc/shutmsg

email user@hostname
-----snip----

I would also sugest your ftpaccess has the following in it

-----snip----
delete no guest,anonymous # delete permission?
overwrite no guest,anonymous # overwrite permission?
rename no guest,anonymous # rename permission?
chmod no anonymous # chmod permission?
umask no anonymous # umask permission?

# restrict uploading in the ftp archive

upload /oolon/ftp * no
upload /oolon/ftp /pub/incoming yes root ftp 0640 nodirs
upload /oolon/ftp /bin no
upload /oolon/ftp /etc no
upload /oolon/ftp /usr no
upload /oolon/ftp /private no
-----snip----

3) Where to go from here.

We should now have a fullying functioning generic ftp archive, the wuftpd
documenation should help you will the rest, have a look at

Hello

I've seen so many FAQ/HOWTO/DRAFT etc ... in this list
Why is it impossible to coordinate the efforts with Koo V. D. H.
the FAQ maintainer ?

So this yet another Solaris faq will not be wasted

There is another wu-ftpd FAQ from 'paradise cowgirl'
maybe you can check with her|him also

Steve,
OK. I dont know why though (I use this method).

You can also start the ftp daemon with the -u option and an argument of 133.
eg

ftp stream tcp nowait root /local/sbin/in.tcpd /pub/ftp/in.ftpd -a -u133

That set the umasks for all clients.

for anonymous and any other users (say real) which need to have a mode

- if you have a class limit.
let say you have a limit of 10
Those zombies deny access to valid connection
- clobbering syslog
- invalid entry in your process table

If you allow 400 connections and xfer 10 GIG a day
seeing this message is not alarming, unless it came
from the same process again and again
And it that situation I would change the code
and notice syslog at every 60 iterations.

Perhaps some work should be put into serving the information in a sane way
to get rid of this problem? I'm currently writing a 'bandwidth' server
which could double as a ftpaccess server... This would also probably be
handy in a standalone version of wuftpd since the communication method would
already be in place. Any comments from developers (of which I'm not one :)?

Chris...

Any ideas..

Hi,

I just installed wu.ftpd with a guestaccount. Everything seems fine, but
when I connect from a linux box, I see nothing when I do a ls. From a
DOS-Box under Windows it works. What could the problem be?

Subject: binding user to virtual ftp address?
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Status: OR

Hi,

I'm looking for a way to resctrict users in the virtual servers
they may access. user1 should only be able to get an ftp session
to his directory on x.x.x.x and user2 should only be able to ftp
to y.y.y.y, although both IP addresses are served by the same
machine (both have a dedicated ftp login/password on the server).

Is there any way to set something like this up? I didn't find
any hints in the last few months of the mailing list archive,
but then maybe the solution is so obvious that no one talks
about it...?

With the default setup, anyone with a login on the machine can
open an ftp session to any of the addresses served...

Thanks for your help,

Alex.

You need to read the guest howto below. 'ls' must be set up as described
in the howto, even for anonymous.

Subject: syntax for archive search?
X-Mailer: Microsoft Exchange Server Internet Mail Connector Version 4.0.994.63
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Status: OR

I would like to do a search of the wu-ftpd
list via the email interface rather than "live"
but I'm having problems with the syntax.
I haven't been able to come up with the
correct "archive name" as specified in the "help"
file that I retrieved.

According to the help file, the syntax is:

<search archive | path-to-archive>] [/password] [-all] <pattern>

I thought it should be

search wu-ftpd /856884838 "guestserver" OR "anon.ftp.server"

But this generates an error: "wu-ftpd: not a valid archive or path."
(whether upper or lower case.)

I've tried also:

search ftpd (ditto remaining fields as above)
then
search wugate.wustl.edu
then
configuration wu-ftpd (to get archive path)

also
run wu-ftpd (which returns a totally blank page but no error)

I want to search for the pattern "guestserver" OR "anon.ftp.server".
I've tried with and without password

Any help would be greatly appreciated. Maybe this archive
search is broken and I'm the only one who doesn't know it?

Restricting access? In what way anonymous ftp? Have you created an "ftp" user?
Have you created the ftp archive structure?

I just recently installed Beta 13 of 2.4.2 and the non beta final
release of 2.4 on 2 diffrent solaris machines. The non beta works like a
charm. The problem with the beta is that it doesn't seem to process the
/etc/ftpaccess file. It never displays any of the msgs set in there and it
ignores all the virtual setups. Anyone else heard of this problems?

I installed wuftpd on a RS/6000 running AIX4.2 a few months ago. I was informed a few days ago that if you access the ftp site via the web page, it only prompted the user to download a file if it had a .tar, .tar.Z, or a .tar.gz extention. All other files were just displayed by the browser. Is this normal behavior? I want to be able to ftp anything, i.e. README files, programs (*.c), etc. Is this possible? (Besides making sure everything is tared up).

Thanks

I believe, if you select the file you want via Netscape with your RIGHT
mouse button, and select the 'Save link as...' menu item, it will automatically
bring up a dialog box to let you select where to ftp it to on your local
system, and after you do that, a ftp transfer status box appears.. Try it!

standalone as is not start by inetd ?

It might not have been compiled to automatically have it use the ftpaccess file. Try putting starting it up in the inetd.conf with the -a option "ftpd -a". Or, you could have missed something that I almost missed. Go to your beta 13 src directory and type "ckconfig". That will let you know if the ftpaccess file is even found. When I installed beta 13, the default directory for the ftpaccess and a couple of other files was different then the 2.4.2 release version. If I hadn't run the ckconfig as the directions indicated, I would have had the same problem. I hope that helps you and that I was finally able to make a contribution to this list after all the help that I have gotten from others here.
BTW, can someone tell me what file and line to put the -a option in so that it will compile it so that I don't have to use the -a option to start it up in the inetd.conf file?

Thanks

This a client(web browser) configuration problem, there is nothing you can do
on the server side. Ftpd just send the file down the wire.

In short, if the web browser doesn't understand an extension it will save
it on disk(normal behaviour). This behaviour can be change with the mime.types and mailcap
See options and read about MIME.

I'm not sure if understand the question, but what's wrong with
"Save As.."

Or in netscape if you click the third button and click
"Save Link as .."
The file will not be display but save on disk

The problem your having has to do with the web browser. Since browsers
typically can show .txt files and other files they will attempt to 'show
them'. Only binary formats that they do not understand (or have helper apps
defined for) will generally 'download'. I am assuming that web browsers are
accessing your files via "ftp://yoursite.name.com/path/to/files/" and not
via the web server.

Make sure your inetd.conf or whatever it is that actually launches wu.ftpd
includes the '-a' flag. The default behavior changed from the non-beta 2.4
to the beta 2.4.2. Don't forget to double check your configuration as
well.. :) I found that I had a really stupid error in my inetd.conf file
that "looked" right but in fact was slightly broken.

I was informed a few days ago that if you access the ftp site via the web page, it only prompted the user to download a file if it had a .tar, .tar.Z, or a .tar.gz extention. All other files were just displayed by the browser. Is this normal behavior? I want to be able to ftp anything, i.e. README files, programs (*.c), etc. Is this possible? (Besides making sure everything is tared up).

This behaviour is comtrolled by the Web browser, not the FTP daemon.
In UNIX Netscape, if you hold the shift key down when you click on the link
with the usual (left) mouse button, it will automatically download the file
to disk for you.

You can also get this behaviour by clicking on the link with the right mouse
button, and choose the "Save link as..." option from the pop-up menu which
appears.

However, you can also change the _default_ behaviour by going into the
Options => General Preferences... => Helpers
option from the menubar, and changing the appropriate MIME configuration
mapping.

On my Netscape (3.01), I have the following mapping set :-
application/octet-stream Save To Disk
and as a result, all my FTP files are downloaded to disk when I click on
them normally (ie. unshifted) - I don't get them displayed on screen even
when they aren't tarred or compressed.

I think this is the behaviour you are after, so you might like to try
setting this and see if it works for you...

Good luck !

Cheers, Bob

Hello,

Recently I have been trying to get wu-ftpd 2.4 to compile on this
IRIX 5.3 box. I was unsucessful. I found a .inst package and installed
it, but it does not support Virtual FTP, which is the main reason why
I'm upgrading FTPD. If anyone have a IRIX 5.3 port, or a .inst file that
was compiled with -DVIRTUAL please help me out, thanks.

Hi again :)

Have any of you actually ever gotten virtual ftp to work under IRIX 5.3?
Or know anyone that has? I've got it compiled with -DVIRTUAL in the
CFLAGS: and It doesn't seem to be affecting anything, the root directory
of the virtual ftp is still the same as the real domain. Maybe IRIX
doesnt support it? Any comments or suggestions?

Check your configurations. Make sure your ftpaccess file is setup
correctly and wu-ftpd is being launched with the -a flag to use wu-ftpd.
If your trying to do virtual FTP with something other than anonymous ftp
login, check and make sure you have a guestgroup option setup in your
ftpaccess file.

If beta12 is like beta 11 it doesn't do logging unless it's
specifically designated in the virtual section of the ftpaccess file.
There isn't a default.

Hi all,
can you allow/disallow different users to get/put certain files only?

eg: user X : only allowed to put get files called /tmp/abcd
user Y : only allowed to put get files called /logs/cccc
user Z: only allowed to put get files called /tmp/local/pppppp
user J : only allowed to put get files called /users/qw.ps

Is there this much functionality in wu-ftp???
Any help would be greatly appreciated.

Maybe playing with the Unix user/group files/dir permissions is simpler

I've sucessfully got beta13 running on HP-UX 10.20, and have set up guestgroups
according to the FAQ. I have set up a drop off point as follows:

upload /home/ftp /incoming yes root hp 0660 dirs
upload /home/ftp /incoming/* yes root hp 0660 nodirs

/incoming has perms 0753 root:hp.

When users create directories in /incoming, they are created with permissions
of 0753 ftp:ftponly. Is there a way to chown or chgrp these directories on the
fly? This isn't really a problem as anonymous users can only see the files in
these dires and not retreive them...

Any thoughts would be greatly appreciated.

Problem 1. No email list server housed at the home of the list.

Problem 2. Not a good idea to put you passwords in requests for help
sent to net lists. (I XXXed the password above.)

# But this generates an error: "wu-ftpd: not a valid archive or path."
# (whether upper or lower case.)

There is no archive so this is a correct and valid outcome.

Alice, do you have web access ? If so go to the list archives at

http://www.landfield.com/wu-ftpd/mail-archive

If you don't but have ftp access you can grab the mail archives from

ftp://ftp.landfield.com/wu-ftpd/mail-archive/mailbox

Sorry I don't have an email access to them at present. I'll see what
I can do in the future.

Subject: Bug found
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Status: OR

Hello. I found a bug in wu-ftpd-2.4. Below is a description of the bug,
and a patch to fix it. It was causing erratic denial of service for
users with entries in the ftphosts file.

Symptoms:

Some users get odd messages and are unable to connect. It only happens
with users that have entries in the ftpaccess file, and does not
happen with all IP addresses. The server core dumps, as detected by
a core file for ftpd, usually in /.

Cause:

The hosts in the ftphosts file are stored in an array called
ha_hosts[]. While checking for a matching host, this array is
sequenced. Sequencing ends when a match is found or the value returned
is NULL. When the array is full, sequencing will go past the end of
the array, causing a core dump.

Fix:

Add a range check to the sequencing of the ha_hosts[] array.

Dan Niles

Mirroring seems a client sort of thing. I'm not sure what a server would
do to support it.

I've used a program called "mirror", available at
ftp://sunsite.unc.edu/pub/packages/ftp-archive/mirror/. This worked fine
for me, but I wouldn't mind hearing suggestions from others.

I am hoping to set up an anonymous ftp server using wu-ftpd 2.4 on a
Solaris 2.5.1 system. Everything was going well, until I tried to create
the neccessary device files (tcp,zero, etc).

When I tried to create device files in AFS, for the chrooted environment,
it fails. After a few moments with the AFS FAQ I discovered that you
can't create character or block special files in /afs.

Has anyone found a way around this? I would like to have anonymous
chrooted into AFS between the access permissions are so much stronger, and
we can so the files in AFS instead of on local disk.

mirror is good and it's what I use, I've also heard good things about
wget, a new GNU mirroring tool, but haven't used it yet. wget is available
at ftp://sunsite.unc.edu/pub/gnu/wget-1.4.4.tar.gz. Btw, the mirror on
sunsite is out of date, thanks for pointing it out to me. SunSITE UK is
the authoritative site for mirror, I believe the current version is 2.5.
Guess we need to update our mirror mirror. :)

Another client that can be used for both html and ftp mirroring is wget

Yes, I have done it on several machines. You can take a small partition,
say 10MB or so, do a newfs on it and then mount it on
/afs/cellname/ftparea/dev Then you can make udp, tcp, zero, and
ticotsord and everything should work fine.

we are using wu-ftpd and AFS on solaris 2.5.1, and I make a memory-based
file system at boot time for ~ftp/dev

A work arround would be to mount your /pub directory in afs, and leave the
rest as a normal file system, which allows character special files.

HI does anyone have a patch that allows wu-ftpd sending a checksum for a
trasmitted file back to the sender ? i tried with EXEC but it doesnt help
to much. The problem is that have to be sure that the file is transmitted
correctly.
btw: is not my idea but the data are imported and they have to be ok

Hello, I think it may be some fault with our configuration, because I have
set it up to only accept uploads in /incoming and not accept creation of
dirs in that dir ..
but as you see from the xferlog someone managed to get past it.
(sorry about the format .. pine you know)

here is the stuff from ftpaccess
(I run wu-2.4.2-academ[BETA-12] with in.ftpd -u022 -a -l)

# specify the upload directory information
upload /home/ftp * no
upload /home/ftp /incoming yes adm ftpadmin 0060 nodirs
#this work .. but then we need some .lsm so that adm know where to put the files ..

upload /home/ftp /bin no
upload /home/ftp /etc no
upload /home/ftp /usr no
upload /home/ftp /dev no
#just some defaults .. shouldn't be needed .. but got them just in case ..

noretrieve /etc/passwd /etc/shadow core

(I attach the file for those of you that want to see the rest of it)

Hi;

Just installed wu-ftpd-2.4.2-beta-13 on a dec and
noticed I still have a problem with lingering ftp
sessions. Should this have been fixed w/ this revision,
or do I need to patch it.

If so could you point me to the patch-HOWTO?

OSF1 V3.2 41.64 alpha

Thanks
Scot

Subject: Can't get ftpconversions to work, all simple checks

Hi folks,

After a lot of debugging I solved my initial problem, being that
ftpconversions did not work. The solution was in the ftpaccess
file. The lines granting compres, tar and gzip were incorrect. The
simplest way to solve it was by putting an '*' instead of the class
names.

However, compression now works, but something strange
happens when I try to tar something. It does start up /bin/tar and
it does send data over, however, the resulting <file>.tar file is
always 0 bytes big !?!?!?!

Does anybody know what is going wrong there ?????

Any help will be greatly appreciated.....

PS.: Here is my ftpconversions file again:

Hi folks,

Sorry, I solved this problem also. The library file 'libsocket.so.1'
was missing from the chrooted library directory.

Greetings,

Thank you for that valuable hint. I too have encountered that problem
(ftpconversions didn't work).

That's not the case with my installation. You can test it with
anonymous ftp:
ftp.informatik.fh-wiesbaden.de

I've testet it with:

get dirname.tar
get dirname.tar.gz
get dirname.tar.Z

and everything was ok after replacing the wrong parameters by '*' as you
suggested.

Yes, I think this is a fix|feature|bug(pick any two :-).

the 'upload' directive will only take effect if root_dir match
the passwd field, i.e. only the underlying Unix
file permissions will do the restrictions if they mismatch.

Let me cut and paste for you

FIXES-2.4.2-BETA-11:
...
ftpaccess.5 now clarifies the fact that the root-dir specified in
the upload configuration line MUST match the home directory in
the operation system password database.

there was a discussion a year back with the 'nodirs problem'
and a patch provided by Bob Myers. But i think everything
was integrated in beta-12.

Does your tar binary require shared libs? If you're unsure try to recompile
the GNU sources with gcc and "-static". This worked for me, I had the
same problem with downloaded tar files being 0 bytes in size.

So long,

some ftp clients(i.e ncftp) can understand site so:

ncftp> site chmod 755 file

some don't then:

ftp> quote site chmod 755 file

of course the ftp server on the other side must implement those extensions
wu-ftpd understands those directives.

Try running a crontask or if you don't mind doing it manually, make it a
shell script, which does this:

cp /dev/null ~ftp/README
find ~ftp -name .message -exec cat {} >>~ftp/README \;
exit

You might want to beautify it a bit, but that should do what you want.

Use a PERL script (you write) that checks every file/directory and
catalogues them and extracts the description of the file from within the
file itself either:

a) on a specific line of the file.
b) or with special text like DESC: this file is the blah blah.

You can let the cron daemon (through crontab) execute the script every x
minutes, hours, days, etc...

Something definitely changed in the interpretation of the 'nodirs'
directive between BETA-11 and BETA-12. We installed BETA-12 here at
wuarchive, and about 3 weeks later I realized that the nodirs wasn't
working, as a bunch of software pirates had maxed out all of our drives :(

I switched back to BETA-11 and things work normally. Anyone know what
changed for sure?

I don't know if this is a list server or not, but I am trying to find someone
that supports wu-ftpd. Question below..

thanks Jim

We have WU-FTPD(2.4) running on our
site. Question is this. I don't seem to be able to use "quote site group or
groups" to change to a group that would allow me access to certain files.. for
example .. If I have access to groups(via /etc/group) "test, ediadm, users" in
that order.. If I ftp to my server and log in with a valid UID (not anonymous)
I can get files that have permissions of "644", but if I go to a directory
that has permissions of "755" and a file in that directory with permissions of
"640", and that file is in group "users", I get permission denied. Ok, I
should.. then I use "quote site group users" and ftp say group accepted, but
when I use the 'quote site groups' command I get returned to me a blank line
and I also get permission denied when I do a get. Do I need to have
"ftpgroups" in /etc? I think I have missed something somewhere.. Hope I gave
you enough to go on. Thanks Jim

Jim, you didn't mention this in your message (you may have thought it was
obvious), so I'll say it to make sure you know... You need to follow up the
quote site group users
command with a
quote site gpass <password>
command, supplying the relevant password for the group entry, in order
for the change to take place. Until and unless you supply the correct
password, you can't change the group.

As you suspected, the group entry must be in the /etc/ftpgroups file (along
with the encrypted password). For my installation, this file is at
~ftp/etc/ftpgroups, with /etc/ftpgroups being a link to the same place,
so that the command will work for both regular and anonymous users.

I hope this helps !

Cheers, Bob

To add to Mr Luckin explanations
you should also have
private yes
in ftpaccess
check the path with ckconfig

I had wu-ftpd 2.4 setup on my FreeBSD 2.1.6
machine and guestgroup chroots worked fine.

I tried putting Academ's 2.4.2 beta 13 and
guestgroups stopped working.

Both are using the same ftpaccess file.

Is there something obvious that I'm overlooking?

Please help.

I'm just starting an install of wu_ftpd (13) on a Sun running Solaris 2.5.1

>From scanning this mailing list for the last several months I have seen many
references to building a statically linked copy of ls. But have not actually
seen simple step by step instructions for doing it.

Can someone point me (or explain for all on the list) how to build a static
copy of ls.
So far I have downloaded GNU fileutils-3.16. It compiles all modules just
fine. just not static.

If I run truss on the new ls command it has reference to:
open("/usr/lib/libintl.so.1", O_RDONLY) = 4
which looks like it is still using libraries.

After ls is compiled
I assume that by placing ls in the ~ftp/bin directory and maybe even
~ftp/usr/bin that I will not have to include any of the libs (~ftp/usr/lib)

After this step I also assume that the same will hold true for customer
directories. ~user/bin and ~user/usr/bin will have the static copy of ls in
them. But I can omit replicating any of the libs in ~user/usr/lib.

Also any pointers to any FAQ's on installing and setting up wu_ftp would
also be appreciated. I have the O'Riely stuff just looking for other
comments. Can't have too many references. (or can you :-) )

Thanks in advance.

You don't need a statically linked ls for wu-ftpd to work properly on
Solaris 2.5.1. If you really want to try to build one, the
comp.unix.solaris FAQ discusses your options.

Ah, if that's your reason for pursuing a statically linked ls, then there
is another way to avoid 100 copies of libc.so in the ftp tree: Use
loopback mounts. They're like symbolic links, but (unlike symbolic links)
will work in a chrooted environment.

Here's a simple example of a loopback mount in /etc/vfstab on our ftp
server to make /usr/ftp readonly. The real filesystem where ftp stuff
lives is /local/ftp:

/local/ftp - /usr/ftp lofs - yes ro

You could do something analogous to make /customer1/ftp/lib,
/customer2/ftp/lib, ..., /customer100/ftp/lib loopback mounts of ~ftp/lib.

Or if you are worried about space you could just do normal links
(not symbolic ones) so long as your ftp archives are on the same file system.

If you read the solaris 2 faq there are good reason not to staically link
binaries that use nsl, intl etc, such as if you patch your computer, they may
not work, or be less secure.. or so I am lead to believe.

Well.. I haven't changed the config and I just tested it (I've been
bitten by the hidden incoming dir before). Making dirs is still rejected.

Surely this is an entirely spurious argument: if you patch your system
the copies of the libs in ~ftp are left entirely untouched unless you
manually update them. There is little difference between having to
recompile a statically linked executable or having to copy a dozen or
so libs every time you install a patch. Both processes could be
automated, but recompiling uses make and thus is already automated.
Either way, it's down to the sysadmin to remember that intervention is
necessary, though. Not having to touch dynamically linked executables
after a system patch is only true if they are using the system
libraries, which is not the case in a chrooted environment such as
anonymous ftp where they are using separate copies of the libraries.

I changed the permissions on incoming to 777 and it worked fine. The only problem that I am having is that I can't seem to get the owner and group to work. Your example below says that any file that is uploaded will have the owner and group of root:daemon. Mine always comes up as ftp:30000. Got any suggestions? I really need to be able to have that as something different.

Never mind on my question about setting the group and owner of the files to something other then ftp:30000. I finally figured it out. I had to add it to the root upload also, like this:
upload /export/ftp * no skb customer 0600 nodirs
upload /export/ftp /incoming yes skb customer 0600 dirs

If I had the following, it would leave owner and group as ftp:30000
upload /export/ftp * no
upload /export/ftp /incoming yes skb customer 0600 dirs

Beta-13 took care of some problems but not all.

One of the reasons is that in TCP/IP it's not easy to detect when a peer die.
Another was deadlocking, but it was seldom.

Solution was propose , but I don't know if Mr Barber
was listening or how easy is it to implement( in a portable way ).

1- use a global timer
2- use keepalive
3- use a probe

Hi,

In order to be able to SEE THE CONTENTS of a guest/anon. chrooted directory (ls
actually giving a dir. listing, instead of a 'blind') on an IRIX system, the
following information may help:

Since I didn't came across a particular IRIX notation in this information:

> guest howto: ftp://ftp.fni.com/pub/wu-ftpd/guest-howto
> OR
> send mail to "[email protected]"
> (immediate autoresponder; subject does not matter)
>

it may be a helpful addition?

Here it is:

=======================================================================
(ftp://ftp.fni.com/pub/wu-ftpd/guest-howto)
OS DEPENDENCIES / QUIRKS

<...>

IRIX (5.3, 6.x)

(as in SUN 4.1.x, but without /dev/tcp)

Create a ~dev/zero device for the FTP directory as follows. (tip:
search on 'dev/zero' in your IRIX systems' Online Books.)
Run the following 'ls' command, then create the devices in the ~/dev
directory with the 'mknod' command, using the major and minor numbers
from the 'ls' results (thanks to Jim Davis <[email protected]>).

ls -lL /dev/zero
cd dev
mknod zero c <major> <minor>
cd ..
chmod 555 dev

You may also wish to use the following method to create the device,
per Ian Willis <ianw.sco.com>; repeat this command for each device
(zero, tcp, etc.).

find /dev/zero -print | cpio -pd ~ftp

Also, you probably need the following shared libraries:
~lib/rld
~lib/libc.so.1
(found in /lib)

Also read the manpages on FTPD, or look in the IRIX Insight Library
(Online Books) in the book/chapter "IRIX Admin: Networking and Mail"
for the paragraph 'How to Set Up a Proper Anonymous FTP Account'
(search helps:-)) on your IRIX system.

Hey

Hi,

Just got onto this list, but already have been digging trough some information
pages searching for the following:

If a 'general' Anonymous ftp account is set up, and ~ftp will end up in
/my/local/ftp/files (passwd: ftp:*:777:777:ftp:/my/local/ftp/./:/bin/true),
only the information under this tree (within ~ftp) are accessible.

BUT... in case a system has one ore more places on disk(s) that should be
accessible for anonymous usages (obviously outside the ~ftp tree), this can't
be done it seems.

Only HARDlinked _files_ seem usable, but this can't be done on directories.

Therefor I wonder if it wouldn't be nice to have an option in 'ftpaccess' where
virtual extra_paths could be added?

Something like:
virtual /books /usr/local/bookshell/export
virtual /mags /disk4/shared/magazine/files
..
(maybe with a guestgroup designation as 4th?)

If anyone has other suggestions, I like to hear them.
Grouping all under ~ftp, is not desired.

NOTE:
the PASSWORD FILE entry:

foobar:*:123:456:ftp:/my/users/foobar/./:/bin/true
----------------------------------- ^^^^

is INCOMPATIBLE with Netscape Ent./Ft.-Server if this user foobar should also
be accessible through http://www.foo.bar/~foobar. Netscape Server refuses a '.'
in the entry, amongst others. Just FYI.

Can't see how to make this work. Anonymous ftp chroot()s, so it _can't_
get to anything "above" it's new root. This is for security reasons.

Hmm...maybe we have an oddly configured ftpaccess file. Anyhow I saw
Alain's post about the home dirs needing to match; that was probably the
problem.

Thanks for the response(s).

Agreed. There is an alternative, though...

You should be able to make a loopback mount for a directory which is
physically outside the ftp tree, to a mountpoint inside the tree. It would
then appear to be under the tree... We do this on our Solaris 2 system,
effectively putting additional "pub" directories (which are physicallly
on different disks to the one containing the FTP root) under our FTP tree.

Cheers, Bob

chroot is chroot. Really. It's not some feature of wu-ftpd, it's an integral
part of Unix security.

The only way to get what you want is loopback-mounts via loopback-filesystem
or via nfs.

I recently upgraded a SunOS 4.1.4 system from wu-ftpd version 2.4 to
2.4.2-academ[BETA-12]. In the process, the remote host references in
xferlog, syslog files, and wtmp are logged only as IP addresses.
The older version logged mainly as (resolved) hostnames except when a
reverse lookup wasn't possible. I have looked through the faq and
the archive search at http://www.landfield.com/cgi-bin/wuftpdsearch,
but haven't found mention of a similar occurence. For ease of use
in quickly identifying recent connections, having the full hostname
available without additional preprocessing would be ideal.

Any advice is appreciated.

I have updated the guest howto with the following information for IRIX.
Many thanks to Frans for supplying it.

A few weeks ago I also updated the Sun information about allocating the
devices properly; a couple of list members contributed information to
round that out. I lost the attributions somewhere, for which I apologize.
If you recognize that you contributed something I'll be glad to add your
name to it.

If you see additional information that would be useful either as
corrections to the overall document or for specific platforms I'll be glad
to add it.

A somewhat related remark/question, although not usable for this particular
problem:

Did anyone implement the correct handling of symlinks, so that for example
"cd" follows the "symlinked path" (like the shell built-in "cd" and "pwd"
commands do). We once made a quick hack to wu-ftpd, which seemed to work
at first glance, and if there is general interest it would be nice if this
could be integrated in the official version.

On a large ftp-server we co-maintain, this feature is really needed: we have
divided the packages in a number of volumes (physical filesystems) and
the "logical" /pub tree only contains directories and symlinks to the
/vol/* trees (all relative symlinks, of course, so that they can be used
in a chroot environment). We want the users to "stay in the /pub tree",
so that they not see the /vol/* stuff (they _may_ see it, but only if
they explicitly ask for).

Of course, we could also use loopback mounts or so, as described in one of
the other replies to the original problem, but this is not a nice solution
for this problem, if you have 100+ packages to maintain.

wu-ftpd does not handle symlinks, Unix does. When I put a relative
symlink within ~ftp which points to another location within ~ftp it
will be followed.

So, according to the standards, wu-ftpd handles symlinks perfectly : it
ignores their presence and acts upon the item the link is pointing to.
The 'pointing to' is of course within the current process environment.
Which is different from a normal environment due to the chroot().

Again : chroot() is a Unix function, and does exactly what it is
supposed to, change the root dir of a process. Which means anything
outside that new root is unreachable.

Possible solutions :

- mount your extra public disks within your ~ftp tree.

- set the homedir of ftp to /, which can have large security implications.

- or use disktools which create one large logical volume from all your
partitions, so you can move certain packages out of/into the ~ftp dir
with one mv command.

To translate it into normal English : you can't have your cake (a secure
chrooted environment) and eat it (symlinks outside that area) too.

I want to make incoming files unreadable until they've been checked
so i have the following in ftpaccess..

upload /var/ftp /test yes root daemon 0600
upload /var/ftp /test/* yes root daemon 0600

This works great. However, if an uploader does a mkdir, the directory
is created :

drwxrwxr-x 3 ftp ftp 512 Mar 21 11:07 subdir/

Basically I want to make any new directories root owned and with "t" set
(so they cant delete any unchecked files in there) ie:

drwxrwxr-t 3 root ftp 512 Mar 21 11:07 subdir/

I dont want to slap on a "nodirs" and i dont want to deny anonymous to
delete (because i want it to be able to delete files after theyve been
checked and chown'ed to ftp)

Any ideas ?
TIA

This I all know very well: I asked for something completely different.
Let's give a simple example:

- symlink pub/linux -> ../vol/linux
- vol/linux/... contains the real data

Now I have a ftp session:

cd /pub/linux
####### (1)
cd ..
####### (2)

At (1), the "pwd" command gives "/vol/linux" (like what /bin/pwd would
do using the UNIX shell), not "/pub/linux" (what the shell built-in pwd
would do).

At (2), you are really in "/vol", not in "/pub", as I would like to see.

So, what I really asked for was to let wu-ftpd deal with symlinks like
the shell built-in commands do, so that "cd" and "pwd" act the same as a
(modern, symlink-aware) shell does.

Note that some clients, like Netscape, do this path interpretation at
the client site (but Netscsape doesn't let you explicitly do "pwd" or
"cd ..", but only displays the current directory and let you go "up
to higher level"). But I would like to see the server handle this.

I know, I know... (I extensively make use of chroot environments for
webservers, sendmail, etc. in firewall configuration ;-)).

That is not what I asked for: the original question had this requirement,
and I know this is impossible (without something like special mounts).

Hopefully this clarifies my question...

Ahhh... why didn't I think of that earlier... nfs. Actually on this Irix
system, NFS loopback links are not permitted according to it's Adm.Guide- but
it links fine to an alias-name of the local system.

But please, can you explain the 'loopback-filesystem' concept? Or give the
syntax?

According to Netscape it's not a bug, but a feature. To circumvent a possible
security breach, I've been told. So I figured it's helpful information.

What if you have in {~ftp} (I'll use the {}'s to indicate a chrooted env.), a
directory {~ftp/vol} which maybe a loopback link or real-path, that is only
d--x--x--x (not readable, only accessible). That contains your
packages/directories.
And use in your 'ftpaccess' file the:

# cdpath
cdpath /vol
cdpath /

entries?

a {cd "foobar"} in {~ftp} will result in the client ending up in
{~ftp/vol/foobar}. This option I found by accident working here, 'cause I
wondered how one would end up in a subdir. that wasn't in the {~ftp}.

I hope I understood the casus correctly.

groetjes,
frans

Here is the procedure (it might be quite different in its syntax on your
IRIX box, the example being taken on a Linux box, but the concept is the
same ):

export your local filesystem:

raistlin@palanthas:[~]$ cat /etc/exports |grep dos
/dose/images localhost(ro)

Verify the export:

raistlin@palanthas:[~]$ showmount -e palanthas |egrep "(Export|dos)"
Export list for palanthas:
/dose/images localhost

Create a directory to hold your export under your FTP home dir:

raistlin@palanthas:[~]$ ls -ld /home/ftp/pub/images
drwxrwxr-x 14 root system 16384 May 24 1996
/home/ftp/pub/images

Then mount your export under your newly created dir:

raistlin@palanthas:[~]$ cat /etc/fstab |grep ftp
palanthas:/dose/images /home/ftp/pub/images nfs defaults 1 1

I hope this helps.

I have used it on Solaris, and I know it's available on Linux (kernel
option CONFIG_BLK_DEV_LOOP).

On Solaris, mounts look like :

# /sbin/mount -F lofs / /mnt
# /sbin/mount
[..]
/mnt on / read/write on Fri Mar 21 15:42:09 1997
# /sbin/umount /

You'll have to check the manpages of other Unix versions to see if
loopback filesystem is available there.

I've modified beta 13 to support explicit ownership and permissions
for directories. I tried to avoid all race conditions which may occur
due to the non-atomicity of an mkdir followed by a chown, but can't
provide any warranty. I've not yet looked into the problem with mkdir
./something. Here's the description of my changes and the patch file:

-- 8< ------------------------------------------------------- >8 --
Bug Fixes
-- Lines in ftpaccess containing \# may still contain a comment
starting with # (in acl.c)
-- If the first line of the ftpaccess file contained a #, the parser
tried to look at its predecessor to find out if it was quoted.
Now, the buffer has a leading '\0' (in acl.c)
-- A `reply(530,...' contained two %s, but only one argument,
resulting in a SEGV on Solaris 2.5.1 (in ftpd.c)
-- If a `socket()' failed, errno was later overwritten by close,
but still used in the error message (in ftpd.c)
-- Some unused variables were removed (in ftpd.c)

Work Arounds
-- If SOLARIS_2_5_BUG is defined, no file locking is done,
as this may crash the machine. (in access.c, ftpcount.c, ftpd.c)

(According to Sun's hotline, another work around consists in
making sure that /dev/tcp, /dev/udp, /dev/ticotsord, and
/dev/ticlts all exist as real devices (created with mknod and the
same major and minor numbers, ownership, and protection as the
ones in the real file system) in the chrooted environment of
ftpd.)

New or Modified Functionality
-- The upload directive in ftpaccess may additionally specify the
protection and ownership of newly created directories
(in extensions.c, ftpd.c)
-- Directory creation must explicitely be permitted (in extensions.c)
-- Command line option -d dumps contents of parsed ftpaccess file, so
now (in ftpd.c, acl.c)
-- Directives in ftpaccess may be marked as using the complete
remainder of the line (minus leading/trailing whitespace) as their
argument (e.g., email). The code assumes that strtok() works
exactly as specified by ANSI C. (in acl.c)
-- The user and group in the upload directive may be specified as
numbers (in extensions.c)
-- A user or group of -1 in upload suppresses the corresponding change
of ownership. This does not rely on your fchown() supporting this
feature. (in ftpd.c)
-- DELE and RMD check permissions and log the action in the same way
when removing a directory (in ftpd.c)
-- if the first # in an ftpaccess line is quoted, the next one will
still introduce a comment--formerly, all subsequent # were assumed
to be quoted, too (in acl.c)

All user visible changes (besides the funny '\# #' behaviour) are
documented in ftpaccess.5 and ftpd.8

Koos is right; however, 'hard' links out of the chroot area, within the
same physical disk partition, do work. I use this to link back to a
single instance of statically linked utilities (ls, etc.) outside the ftp
trees. Just make sure you have the files owned and permissioned correctly
so they cannot be overwritten.

I don't know whether you did, but I don't think your answer solves my
problem (I guess cdpath does a similar thing as the CDPATH environment
variable in most shells).

But take a look at ftp.nluug.nl (the system I'm talking about) with a
"normal" ftp client (that is, no Netscape or such), and do

cd /pub/os/Linux/distr
pwd
cd RedHat
pwd
cd ..
pwd

to see a "real-life" example of the problem I'm trying to explain.

Note:
pub/os/Linux/distr
is a symlink to
../../../../site/ftp.redhat.com/pub/redhat
which is a symlink to
../../../vol/1/linux-redhat
All three (vol, site and pub) directory trees are accesible by the
user, but normally he only needs to use the pub hierarchy.

This makes the maintenance of all the stuff a lot simpler (the main
goal was to be able to easily move packages to other physical volumes),
and walking through the tree works fine in the shell, but not using
ftp :-(.

And, again, we did patch a previous wu-ftpd version to handle symlinks
"intelligently", that is, in the way shells handle them. I'll try to
dig up our changes.

I sent a similar message a while back and never received a reply. I want
to automatically give one class of anonymous users access to several
groups. Any idea how to do it? The following does not work even though
the documentation implies it should.

-------------------
class first anonymous *.foo
class second anonymous *.bar
class all real *

autogroup docs first,second
autogroup code first
-------------------

In the above scenario, class first cannot access the code group.

Thanks,
JIm

Why modify the path of users for /home/users/./. I don't make this and
my
solution for chroot users work fine. However I have the problem. Some
users
have your home directory in other device, different of my ftp server.
How do I can make that this users also been chrooted. /dev must
hardlinked
with the ftp home directory.
Thank's in advance!

This is what is commonly called a getwd cache ?

For things like :

koos@idefix:~(504)$ cd anonftpdir/
koos@idefix:~/anonftpdir(505)$ pwd
/home/koos/anonftpdir
koos@idefix:~/anonftpdir(506)$ /bin/pwd
/ftp/ftp/pub/koos

I think your patches can be a welcome addition, maybe as a compile time
option. It's more of an interest to large sites like ftp.nluug.nl then
small sites.

In my never-ending quest for the perfect ftp setup I added some info to
my ftpaccess file and was surprised at the results.
Originally a couple of lines looked like this:
upload /usr/people/ftp * no
upload /usr/people/ftp /pub yes other employee
0664 nodirs

After seeing the recent postings on security and nodirs I added a
"nodirs" to the top line thus:
upload /usr/people/ftp * no other employee 0664 nodirs
upload /usr/people/ftp /pub yes other employee
0664 nodirs
thinking that something looking like a little redundancy couldn't hurt.
It seems that the addition turned on nodirs from / on down (except when
explicitly stated otherwise). It made some real users a little upset.
I was under the impression that the structure of the line whent:
upload <root-dir> <dirglob>
and that the glob was relative to the root-dir. I tried "/*" and "./*",
but that didn't seem to have any noticeable effects. Has anyone
encountered this behavior. I have been on this list for quite some time
and don't remember seeing this one, but if it has been discussed please
ignore my ignorance.

Hi,

I believe recently there was talk of code to enable
bandwidth throttling of wu-ftpd.
Is this available presently ?
I am interested to find out about this, I am
running beta 12.

Any info onthis appreciated.

Thanks much,

Lennard

The code I wrote (it's a hack job) is available in patches at:

ftp://debian.iceonline.com/pub/other/wuftp/

There are a couple of files, and the ones that pply to this are

README
wu-ftpd-2.4.2-beta-12.2.diff.tar.gz

Good luck!

I have installed the wuftp the newest version one more time and
still I am not able to get the dir listing with the user names
and group names instead it gives me the listing of the id numbers.

I have tried to resolve this problem by reading man pages of wuftpd
but it does not mention this issue.

Any help is appreciated ...

I'm in the process of setting up a new server using Linux Red Hat 4.1.
This version of Linux has included wu-ftpd 2.4.2 academ BETA-12[1].

I currently have an older version of wu-ftp running on an SCO Unix 3.2v4.2
(Version 2.4(2) ) box doing this without any problems but there seems to
be some changes in how the ftp directories are setup (No dev directory
for one).

I want to setup a user (catsca) so that they can access only their specific
ftp area. On the SCO box this works. On the Linux box the login always
fails but I don't get a message saying exactly what is wrong.

If I setup the user as a normal user and point their home directory to
simply /home/ftp/username, it works just fine.

If I setup the user as it should be with /home/ftp/./username it always
fails.

The directory permissions look correct, the UID for the account belongs
to the user, the GID is the guestgroup...

I am not using Virtual Host so that isn't the problem...

The only error I see is "failed login"... in the syslog file on the
Linux box...

Any suggestions...

If you want all the user names to be listed in you annoymous ftp archive
you need to copy the full /etc/passwd and /etc/groups files

However this does pose security problems... Personally, I live with the
numbers.

This is the location for the latest wu-ftpd. You can't see the

Found the problem....

The users passwd entry looked something like:

catsca:password:213:63:CATSCA FTP WEB Directory:/home/rftp/./catsca:/bin/false

/bin/false was not in /etc/shells

I haven't seen this one before, but I'm starting to see it with beta-13 :

# ftp idefix

When I tried to debug this, I found out the only way I can reproduce this
is when I try to ftp from the same host to the same host with root running
the ftp client. Any other combination could not reproduce that error. It
also happens some times, not always.

In case this matters, the host is running :

Can someone point me in the right direction -

I'm trying to setup my ftp site so that a user ends up in
their own directory under the ftp tree after they login.

This is the location for the latest wu-ftpd. You can't see the
directory contents, but get the file anyway. It's there.

#1) I am having some problems setting up the WU-Archive FTP server
on a
Solaris 2.5.1 machine. The first problem occurs when I logon using the
anonymous user id, as shown in the following session:

What is the 425 data socket/bad file number error and why do I get it.

#2. I notice that I get an ftpd.log in /var/log on a server that
was set up before I came in. Is the ftpd.log a feature of WU-Archive
FTP and if so, how do I set it up?

Is there a way to limit ftp users from deleting certain files in their

P.S. We are running wu-ftpd-2.4.2-beta-12 on Solaris 2.3/5.

You have to read the Sun man page for in.ftpd. The wu-ftp install overwrites
this man page, so you have to dig it up elsewhere and reinstalled it. In it
you will find a script. Cut it out and run it. Your problem will go away.

Hi.

I'm trying to get beta-13 set up on a client's
SCO 3.2 Release 4.2. From a regular user account,

ls doesn't work
pwd works
file transfer works
delete works

I don't think it's a shared libraries problem because beta-11
works fine with the same ftp* configuration files. Even the
stock SCO ftpd works fine.

What am I missing here?

The man page for "ftpwho" says that the program isn't very useful unless
the server is compiled with set-proctitle. I have looked through the
source and can't find where it's commented out or something. Where am I
suposed to set it? Also, what is the format for the ftpwho output? I
mean, what are all the columns? Thanks.

Is there a way of automatically setting binary mode for
transfers of certain files, e.g. based on file type,
e.g. filename.exe?

The requirement has come to light for people fetching binary files
by web browsers.

the default seems to be for them go go over in ascii mode.

Can I over-ride this at the server end?

Client should be aware of the transfer mode, and there is no way to
notify client about mode from server in FTP protocol. Some Unix clients
always set image mode if remote system is identified in SYST as Unix, too.

Thanks for quick reply Alex.

"status" or "type" can return whether its ascii or binary though,
can't it?

However, as I implied, the real problem seems to be people fetching
via netscape, and not a conventional ftp session.

I don't know if it's possible for such a browser to set the mode,
and the way that people normally use browsers would suggest that
the mode should somehow be set automatically.

Regards,
Mike

The client is the one requesting the file and needs to request what
type of mode it wants the file to be sent.

I suspect that people using Netscape are left clicking on the tag to
download which I believe Netscape then downloads as ascii. If they
right click on the tag, they download as binary ??

You need to invoke in.ftpd with the -a option and use the ftpaccess file.

I have been having complaints from people who tell me that while
they are downloading large files (many Megs), they loose the connection.

I have seen this happen while transferring files via the web;
you sit there and slowly, slowly the file transfers and then suddenly,
mysteriously, the connection drops and you get something link
a "Connection Reset by Peer" message. (Where the "Peer" is
obviously not you.)

Now, I cannot confirm that this is the same problem, indeed, it
may not, but the result is the same.

The problem is reproducible and the only consistenct seems to
be with very large files, or better yet, transfers which take a very
long
time.

Does anybody have any ideas - or solutions???

I too am seeing this, although it seems to be more sensitive on uploads
than downloads for some of my clients.

I think we are seeing the effect of going through overloaded Internet
gateways. I'm not a TCP/IP protocol guru, but I think this is the effect
of too many lost packets. Comments from others would be welcome.

Is there a standard client available for wu-ftpd server? For example,
if my client does not support block mode transfers, can I replace it
with a client that does?

Sasha Romanosky and Michael Brennen talked about "Connection reset by peer"
problems...

We used to see this on our transfers to and from India and (occasionally)
Europe, but we upgraded the connection and it has largely gone away.
We now have transfers which take longer than 24 hours to these site which
can still complete OK.

I don't know the exact cause, but presumably the problem is related to
reliability of the line - Michael Brennen suggested it may be too many lost
packets. It's obviously also affected by the loading; if a line - and/or
the server - is heavily loaded the transfers will take longer, which means
a greater chance of seeing the problem before it completes.

(Sometimes things were so bad that we could FTP to a machine in India,
connect OK, do an "ld", and it would time out before the directory could
be listed...)

Strangely enough, we found that if we telnetted to the remote site, then
ran FTP from there back to our machine (ie. "got" the file from that end
instead of "putting" it from ours, we could sometimes get a transfer to
complete when it would otherwise fail).

Incidentally, we didn't just have this problem with the wustl server - it
happened with the machines' native FTP servers too.

Cheers, Bob

Subject: RE: FTP dropping xfers???!!!
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

Sasha Romanosky and Michael Brennen talked about "Connection reset by peer"
problems...

Strangely enough, we found that if we telnetted to the remote site, then
ran FTP from there back to our machine (ie. "got" the file from that end
instead of "putting" it from ours, we could sometimes get a transfer to
complete when it would otherwise fail).

[And then Matt Said...]
I'm using wu-ftpd beta-12 and don't see these messages very often, but due
to the network setup in our office (we're running two class C's, and the
chunk of hardware between them is very unreliable) we occasionally get FTP
sessions that bail after various time lengths. However, almost always, if
I telnet to the machine, and then do a PUT (as opposed to a GET) it usually
works AOK. Any ideas on why this happens this way? I've always been
curious, but haven't really sat down with my stack of TCP/IP books to
figure out why.

Matt

For anon ftp, the path you specify in the ftpaccess file must be
relative to the base of the FTP area. For example, if your /etc/passwd
file contains:

ftp:x:xxx:yyy:Anonymous FTP user:/export/ftp:/usr/local/bin/nologin

and your ftpaccess file contains:

message /welcome.msg login

The the welcome message will come from the file:

/export/ftp/welcome.msg

as seen from the un-chroot'd filesystem.

You should also read the ftpaccess(5) man page for more information
about making sure that anonymous users are properly handled. There is
also a FAQ on how to make Guest users work.

Why do I get the following message when I login as a guest user:

425 Can't create data socket (0.0.0.0,20): Bad file number.

I have followed the install doc exactly!

# Sasha Romanosky and Michael Brennen talked about "Connection reset by peer"
# problems...
#

This is not a wu-ftpd problem I'll bet...

I've run into this a couple times... Years back I paired a 386 with a Sparc10.
We were constantly seeing "reset by peer" messages on the Sun. After upgrading
the PC to a 486 it went away.

Another time I saw it was due to some hardwiring of timeouts one of the
IP Stack vendors did. The timeout was generated using a clock speed calcuation.
When the software was put on a much faster machine the timeouts happened
quite often. The vendor was red-faced...

Another time I saw it was in a WAN situation where the line was not as
reliable (or as big) as it should have been. Traffic spikes that exceeded
available bandwidth were the problem and once again timeouts bit us.

The point here is that this kind of error can come from various sources
relating to timeouts in the IP stack. You need to examine what may be the
possible cause. Look at the systems you're using, the IP stack software
and the bandwidth its running on. Chances are the solution is more obvious
than you realize.

The thing that makes me point to Internet gateways/transfer points is that
my equipment here is lightly loaded; both the servers and full T1 are
nowhere near capacity. Traceroutes frequently seem to find backbone
transfer gateway delays at times that someone is having trouble
{up,down}loading. When I say 'lost packets', I'm more broadly meaning
packets that either never made it through an overloaded gateway or were so
delayed that they were timed out.

You don't have the /usr/lib with a link? This isn't work, believe me.
If you copy /usr/lib of your ~ftp directory it work fine.

A guest user has been setup on the local machine 'goof'.
When this guest user logs in they end up in the proper
directory, but they can't use ls -> they get

425 Can't create data socket (0.0.0.0,20): Bad file number

This is running on a Solaris 2.5.1 machine - note all of the libs
have been copied the ftp tree.

Also when you login as anonymous, or a real user you can use the
ls withoout any probs.

What's up?

Since it appears that more than one of us have seen it also with non-wustl
servers, it does seem to indicate a more generic problem.

(Good war stories / advice, too, Kent.)

It would seem that we've touched on something here.....

It would also seem that, indeed, this is a symptom of TCP
and not necessarily ftp or http. Makes sense to me.

Now, since TCP was born to be (no, not wild) reliable,
how can we stop these dropped connections - regardless
of delays or lost packets...???

[Oohh, where's Richard Stevens when you need him??]

Hello,

I just installed the 2.4.2 Beta 12 version of the FTPD on a Solaris 2.5
box, and I am having a problem. Normal users are able to connect,
transfer files, list directories, etc... Anonymous users can connect,
but then can not do anything other than change directories and PWD. I'm
sure I haven't tried every command, but I know that they can not PUT,
GET, or LS.

My anonymous tree is set up as follows:

ftp
bin
ls (file)
dev
tcp (file)
zero (file)
etc
group (file)
passwd (file)
incoming
lib
libc.so.1 (file)
libdl.so.1 (file)
libintl.so.1 (file)
libw.so.1 (file)
pub
usr
lib
ld.so (file)
libc.so.1 (file)

Whenever I try to do an ls, put, or get, I get the following error:

425 Can't create data socket (0.0.0.0,20): Bad file number.

Does anyone have any suggestions?

Given lightly loaded systems and T1 here, how much can I reasonably start
looking outside my own setup to Internet traffic bottlenecks? I've
thought for some time that the issue is not ftpd per se, but was more a
TCP/IP protocol issue.

Surely not if the file mode grants no access (w) to the guest.
The .rhosts is used to control rsh access ie a list of host accountname
grant rsh access to the machine.
The .forward is used by the mailer and is also a security risk.

Missing ticotsord and udp; see the in.ftpd man page. (I assume by 'file'
you mean 'character special file'.)

Missing netconfig; see the in.ftpd man page.

You don't need ~ftp/lib.

Greetings, all,

It's been a while since I've been able to work with wu-ftpd but I'm back
to report that the behavior I had with upload permisions for guest group
users under beta-11 and beta-12 is still around in beta-13. I have filed a
"real" bug report with Stan as according to his CLOSED ticket notes with
the beta-13 release, he was not able to dublicate this bug in beta-12.

If you want all the gory details, please feel free to hop on over to
http://www.teleport.com/~minerva/wu-ftpd/bugreport-01.htm and check it
out. If you don't have web access and STILL want all the gory details,
just let me know and I'll forward you a copy.

Up next, an update regarding the Solaris 5.x How-to Guide...

Cheers,
-Darci Chapman (aka Paradise Cowgirl)

Hello, again,

Just a couple of things:

The guide is available at:
http://www.teleport.com/~minerva/wu-ftpd/wuftpd.htm
Feel free to send comments/feedback/flames to me at [email protected]

Now that I've installed beta-13, I will continue work on the guide; items
on my todo plate:
building a statc ls binary
upload permissions for guestgroup users (work arounds)
allowing guestgroup users to change their passwords
reporting tools
ftpconversion
incorporting Solaris 2.4 info

If there are additional items you'd like to see, please feel free to email
your suggestions to me.

Once again, the reason for coming up with this guide was two-fold - I had
to anyway :-) and to make it easier to install and configure wu-ftpd on
Solaris 2.5 without having to reference as many as three different
documents. Having made this guide publicly available, I'm committed to
updating it and maintaining it to the best of my ability.

Anyone is welcome to use the information contained in the Solaris How-To
Guid to update/create other documents. People should feel free to use it
or ignore it as they please.

I hope to have the above items taken care of by 31 Mar.

Cheers,
Darci Chapman

Hello,

I meant to ask in my original post on this topic if anyone using Solaris
5.1 has gotten upload permsisions to work for guest group users and if so,
what your upload directives look like in your ftpaccess file. I really
need to get this piece working asap :-)

Thanks!

Greetings!

We recently disabled a bunch of aliases of the form [email protected],
replacing them with a bot that sends a canned reply when it receives mail.
We've since found out that some of those aliases were subscribed to mailing
lists, and we're busily unsubscribing from them.

The bot told us that it had replied to a message from [email protected],
but it didn't include any information about the message, such as the address
it was sent to. If there are any addresses of the form [email protected]
that are subscribed to mailing lists that you run, please unsubscribe those
addresses at your earliest convenience.

The bot is supposed to ignore mail sent to a mailing list (by checking for
Precedence: bulk or Precedence: list headers), so if this address is in fact
itself a mailing list, our apologies for the noise.

Derek,

the ftpd for anonymous users will chroot
to determine whats wrong with the ls command, try this
truss -f chroot ~ftp /bin/ls | more

where ~ftp is the anonymous chrooted environment. The output of the command
should tell you what needs to be where.

ls should be in bin
the libraries should be in ~ftp/usr/lib

-rwxr-xr-x 1 bin bin 107532 Nov 21 14:10 ld.so.1
-rwxr-xr-x 1 bin bin 664048 Oct 28 1995 libc.so.1
-rwxr-xr-x 1 bin bin 2568 Nov 21 14:10 libdl.so.1
-rwxr-xr-x 1 bin bin 15304 Oct 25 1995 libintl.so.1
-rwxr-xr-x 1 bin bin 39340 Oct 25 1995 libw.so.1

this should at least get you going, you may need other directories and
libraries and devices to get complete directory listings with users and groups.

your problem with get and put sound like they may just be permissions
problems either in the files and directories modes or you need suitable
entries in the ftpaccess file (or both).

Make that http://www.teleport.com/~minerva/wu-ftpd/wuftpd.shtml, as the
original URL doesn't work.

Thanks for making it available Darci, it looks as if it would have been
really useful when I was installing wu-ftpd a while back.

BTW, with some help from another member of the list and a patch for gnu
ls, I managed to build a "static" ls but never managed to get rid of a
stubborn dependency on ld.so. I await the rest of your howto with
interest.

Regards,

John.

Hi!

Some time ago I made a patch for beta12 that allows you to restrict the
port ranges used by passive mode ftp.

This is helpfull for people who dont want to open just a part of their port
space in their firewall.

So far, the pacth is compile time only. You cannot specify in the config
file the port range to use. You have to change the values of PASSIVE_BASE
and PASSIVE_SPAN in the patched ftpd.c and recompile... For ex, if you want
to open ports 4000 to 5000, use PASSIVE_BASE 4000 and PASSIVE_SPAN 1000

Apply to the ftpd.c in the src directory...

I've been working with this patch for a coupple of month now, no problems.

hmms.. I just did that. I compiled ls statically a coupple of days ago.
Used fileutils something-16 :)
I think I have the patch somewhere... I'll dig it up and post it here and
send it to the WUFTP Solaris FAQ maintainer...

I'm using beta12 and beta13 with the static ls and it works very.
I dont have a single lib in my ftp areas.

Melo . o O ( Now where did I leave the patched sources for this thing? :) )

Hi!

I have made a small procedure for compiling ls static on Solaris. Tested on
Solaris 2.5.1 with gcc and fileutils-3.16

Basically I adapted the current procedure to the new fileutils (old one was
for fileutils-3.13) and use the same static-ls.c from Emil.

It might be good to put it online so I'm CC'ing this to Darci who maintains
the HowTo for WuFtpd on Solaris

Melo

--------------
Ok, a small procedure to build a staitc ls.

1. get fileutils-3.16 from your favourite GNU mirror site.
2. Unpack
3. apply the patch (see below)
4. copy static-ls.c (see below) to the fileutils-3.16/src/ subdirectory.
static-ls contains some the functions that Solaris does not provide
statically. This file is the work of Emil Isberg <[email protected]> and
Brett Porter <[email protected]>. Great work!
5. cd into fileutils-3.16
6. run configure
7. make
8. cd into src
9. test with truss ./ls -la 2> err
err should not contain any references to any libs...
file ls should report somethink like
ELF 32-bit MSB executable SPARC Version 1, statically linked, not stripped

10. (Optional) strip ls

You can now copy it into your bin directory.

Files needed.

As we are in a code freeze and will not be adding more features until
the next release (after 2.4.2 is out), this will be held for consideration
at that time.

Thank you! I tried to statically compile ls once before when I really didn't
have the time to do it right... As it was not critical to my operations I
blew it off meaning to get back to it sometime, someday.

Since your message came across I thought it might be a good time to steal
a couple minutes and try again. I just tried your procedure and it worked
great! First shot. 10 minutes to unpack, change, compile and install. :-)

To anyone having troubles with Solaris and dynamically linked ls... Use this!

I've put a copy of your message in my archive as

{http|ftp}:/www.landfield.com/wu-ftpd/support/static-ls.how-to

There is also a copy of fileutils-3.16 there for convenience.

THANKS Melo!

Subject: dir and ls command on our server
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

Hello;

I am a new subscriber and I have a question:

I just installed wu-ftpd V 2.4 onto our solaris 2.5.1 box and have a slight
problem. Our users (using WS_FTP32 in windoze) are reporting that
when they connect they get no listing of the directory contents on the
server and I've found that the ls command works properly but dir does
not. Here is an example session:

331 Guest login ok, send your complete e-mail address as password.
Password:
230 Guest login ok, access restrictions apply.
ftp>
ftp> ls
200 PORT command successful.
150 Opening ASCII mode data connection for file list.
bin
pub
etc
usr
dev
ftp-exec
226 Transfer complete.
35 bytes received in 0.032 seconds (1.1 Kbytes/s)
ftp> dir
200 PORT command successful.
150 Opening ASCII mode data connection for /bin/ls.
226 Transfer complete.
ftp> quit
221 Goodbye.

Any suggestions?

This is the location for the latest wu-ftpd. You can't see the
directory contents, but get the file anyway. It's there.

Hi,

I am trying to fix similar problems too. I think it may relate to
TCP Tuning.

This my checklist:
- the MTU should be the minimal MTU along the route,to avoid
fragmentation
- MSS= MTU +52 to send full packets (to be checked).
- tcp_sendspace= 4 * mss to avoid excessive retranssion by TCP, in
the case of high percentage of packet loss ( use ping with
packet size = average file size) . This should give robustness,
at the expense of throughput, for connections over the internet
- use netstat a lot, look for dropped packets, fragmented packets,...
- if on the internet, disable the MTU discover option
- I don't know about whether or not to allow rfc1323

Any advice welcome, I am not a guru.

But is this mailing list may not be the right place....

Rgds,
Gilles

Subject: ls and dir not working
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

Hi there;

This is a summary to the solution with my ls problem where ls would work
but dir did not.

System: wu-ftpd 2.4 and Solaris 2.5.1 on a sparc.

It turns out ls needed more libraries than I had installed. There were some
complaints in the log file and when I ran ldd on ls I got:
libc.so.1 => /usr/lib/libc.so.1
libdl.so.1 => /usr/lib/libdl.so.1
I installed these libraries and the complaints in the log stopped but
dir still wouldn't work.

However, it turns out, MORE libraries are needed. I should have gone with
my first instinct and ran truss like a list member suggested. There were
two more libraries to be installed. Once done, it worked.

Thanks.

Craig

Could anyone tell me how to make Wuftpd Kerberos aware? We've had a break

Content-Type: TEXT/PLAIN; charset=US-ASCII

I have installed the ftpd on a solaris 2.5.1 machine...

When I login as a guest user and try to create a direcotry
listing using 'ls' I get:

425 Can't create data socket (0.0.0.0,20): Bad file number

But I don't get this message when I login as anonymous, or as a real
user (It works just fine). I have populated the ftp/usr/lib dir
with all the needed libs, as well as the dev files for solaris.

What's going on here?

Cheers

I don't use the guest stuff, so I may not be able to help directly, but...

There is a "How-to" file available at
ftp://ftp.fni.com/pub/wu-ftpd/guest-howto
which may help.

Apologies if you've already seen it (you didn't mention it above).

Cheers, Bob

If you haven't already done so, you might want to check the FTP related bits
of the Virtual FAQ at
http://www.Linux-Consulting.com/FAQ_virtual
to see if there is anything useful there you can include...

Has anyone else noticed peculiar /bin/ls behavior under IRIX5.3?
I have guest,anonymous, and real accounts set in the ftpaccess...the last
two operate correctly. The one for the guestgroup (set up exactly as per
M.Brennen's guest-howto; TNX**googol BTW) "appears" to work in every way
except the /bin/ls delivers a null return for even 555 files and directories
quite happily without complaint, even in debug mode. All other commands
appear to function correctly. Limitations function correctly.

Under IRIX there is no equivalent library to the one in the build below so I
am sad to say I cannot even try this.

Craig,
Try starting the ftpd in debug mode and check the logs to see what get's
rcvd by the ftpd when the client does ls and what gets rcvd when the client
does dir.

Re-reading what I wrote: Re: An Alternative way of supporting virtual ftp
servers, Step 4. You should probably add:

Note that there needs to be a line like

virtual 10.10.10.10 root /var/ftp/virtual/ftp-serv

for each virtual ftp server in the ftpaccess file used by the virtual
server. This line directs the virtual server to the approprite root
directory for anonymous ftp access. If this directive is not present the
home directory of the "ftp" user will be used as root for anonymous ftp to
the virtual server.

(Example virtual command cut from your faq.)

I don't know that the need for the "virtual root" directive was made clear
in my description.

And a correction: You have an an example tcpwrapper configuration line:
>
> [email protected] : ALL : twist exec /usr/local/sbin/ftpd
> -l -a /etc/ftpaccess s/x.meme.com

The path to the ftpaccess file has a space in it and shouldn't. It should
read:

[email protected] : ALL : twist exec /usr/local/sbin/ftpd
-l -a /etc/ftpaccess/x.meme.com

May the Legos (TM) always be swept from your path in the night.

I'm not Stevens, but if I correctly understood what he wrote about TCP
connection closing, it's caused by RST packet, sent to terminate
connection on socket that takes "too long" to close properly where "too
long" is defined in SO_LINGER option. It also depends on how socket
was closed, with or without shutdown() called. "Cure" will be to let
socket close by itself without defining SO_LINGER, but that may take long
time, and still won't save from timeouts in transfer.

Have you built a static ls from gnu? It is much easier under IRIX to build
staticlly linked executables than under Solaris. Use the -non_shared on the
compile and link line and you have to have installed the non shared libaries
which are in c_dev.sw.speclib and compiler_dev.sw.speclib and
dev.sw.irix_speclibs.

I'm trying to install wu-ftpd 2.4.2-beta-10 on a RedHat Linux 4.0

After having fixed the glob.c problem I get the following output when
executing ./build lnx:

-where did I go wrong?

Any hints would be appreciated!

Kim.

Jeff,
I have been working with SGI folk several months trying to build a static
version of ls on IRIX 6.2 unsuccessfully. I am curious about your version
of a static ls that still requires shared libraries to be present? Or did I
misread something?
Thanx,
Roger Hanke

Have you built a static ls from gnu? It is much easier under IRIX to build
staticlly linked executables than under Solaris. Use the -non_shared on the
compile and link line and you have to have installed the non shared libaries
which are in c_dev.sw.speclib and compiler_dev.sw.speclib and
dev.sw.irix_speclibs.

Here is what I did to build static ls on SGI under 5.3. The same should
work for 6.2 although I have not tried.

1. Using inst or swmgr, install the following products (assuming you have
purchased IDO)

c_dev.sw.speclib
compiler_dev.sw.speclib
dev.sw.irix_speclibs

You need these to get the static (non shared) libraries in addition to
the standard DSO (shared) libraries.

2. Get gnu fileutils from your favorite gnu site.

3. Modify the Makefiles after using configure (the lazy method) or figure out
how to give configure the right CFLAG and LD directive which is

-non_shared

That is, you compile and link with -non_shared. You'll then have a
statically link executable for ls (and several other things as well).

We (ftp.lerc.nasa.gov) are using this under IRIX 5.3. If you want to see what
I did with fileutils-3.12 get the following file

ftp://ftp.lerc.nasa.gov/users/tohanson/fileutils-3.12.static.tar.gz

I have a simple wish from wu-ftpd: I want to give different users
access to their own home directory without the possibility of going to
another place. Ideally, they should think they're in the top level -
just as a anonymous user.

I've tried to set up the option guestgroup in ftpaccess which restricts
them the way I want, but now they can't use ls!

What can I do?

The subject says it all...I can't think of anywhere that wu-ftpd makes
assumptions about the year that could cause problems, but I thought I'd
run it by everyone just in case I overlooked something.

Thanks.

Well,

I would probably duplicate the /etc /bin /usr/lib /usr/bin and /dev
directories which exist under the anonymous root hierarchy. Then, since I
am on Unix using Solaris (or SunOS) I would do a loopback file system
mount (type lofs) from that directory to theirs. This gives them the
necessary stuff to at least do an ls. Any other apps they need to use
would need to be put in the bin directory. And if those apps are not
statically linked then the appropriate *.so lib files would need to
included in the new /usr/lib. This is not easy to maintain but it does
work.

Andy,
When I saw this question I laughed. Then I started to think about it
and then I went and looked...

There are three places where 1900 is used explicitly. Two times in
extensions.c and once in ftpshut.c.

extensions.c: tmbuf.tm_year -= 1900;
extensions.c: tm.tm_year -= 1900;
ftpshut.c: (tp->tm_year) + 1900,

ftpshut.c should not be a problem as long as the system time functions do
the right thing. The two references in extensions.c can be handled with an
if statement checking the date > 2000. Question is, are there non-obvious
gotchas ?

Mirroring might get interesting globally if the mirroring software people use
does not realize '00' is not less than '99'. Well, at least for a day or so
until all the mirror sites redownload everything and resync their file
timestamps... I think I'll be on vacation that week.

This should not present a problem. If you look at the manual page for
localtime, you will see that the tm_year entry is the number of years
since 1900. This entity is an 'int'. On 16-bit machines (are there any
of these left?), this means the largest number of years could be 32,767
((2^15)-1); plus the 1900, or 34,667. On 32-bit machines, which most
everyone should be on by now, the number is large enough that no one
should worry about it. For those that care the value is ((2^31)-1) or
2,147,483,647 (plus the 1900).

The code should work so long as they are not trying to stuff the result
into a two-digit output format.

The first occurance in extensions.c is in the code for processing
entries from Shutdown process. This file (specified by ftpaccess)
contains the date/time of the shutdown in a specified format. The
format specification doesn't say whether the year must be four digits,
but it does state it should be greater than 1970. I take that to mean
it must be four digits. The code is scanning this value into the
tm_year field, and then adjusting it by subtracting 1900. For years
greater than 1999, the resulting value will be 100 or more, and that's
just fine. NO PROBLEM HERE.

The second occurance is in a function called newer(). This function is
passed a number of parameters, the first of which is a date string. The
first sub-field of that date string is the year, and it is specified as
a 4-digit year. This value is likewise put in the tm_year field, and
then adjusted by subtracting 1900. NO PROBLEM HERE.

The entry in ftpshut.c is where the shutdown message gets written when
an ftpshut command is issued. The adjustment is computing the date to
be printed in the file, which is later read by the first occurance in
extensions.c above. The value is taken from the tm_year field after the
current time is adjusted for the offset. The number of years in that
field is adjusted by adding 1900. If the year was 2000, then the value
in the field would be 100, and the result of the adjustment would be
2000. NO PROBLEM HERE.

Disclaimer: In the following section, I refer to line numbers in
files. I'm still using WU-FTP version 2.4 here, so all line numbers are
relative to the 2.4 version.

There is one additional place where we need to be concerned in FTP. At
line 1568 in ftpcmd.c, produced from line 701 in ftpcmd.y, we have a
reference to tm_year which assumes a 2-digit value. In fact, it even
has the '19' (century part of the year) hardcoded. The patch to fix
this is:

*** ftpcmd.y- Thu Mar 27 17:01:24 1997
--- ftpcmd.y Thu Mar 27 17:05:32 1997

Mirroring is another issue, and another program. The people with access
to those programs should be checking them to see if they are affected by
year-2000 problems.

Subject: Chroot & cgi Help!
MIME-Version: 1.0
Content-Type: TEXT/PLAIN; charset=US-ASCII
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

Hi all-

I have the wu.ftpd daemon running on my web server to chroot each
user to their home directory when they ftp their home pages to the server.
Now they all want to set up their own brand of guest-book, and what not. So
I compiled Cgiwrap to protect the server from any really wild/insecure
cgi's.

They work great from my own (non-chrooted) directory, but will not
run from a users /public_html/cgi-bin directory on the basis that cgi-wrap
complains there is an illegal "." or ".." in the path, the very "." which
causes the chroot to the home directory.

While I realize this is not 100% on topic for wu-ftpd, I did learn
how to set up the chrooted env from Mike Brennan and figure some of you
must have run into this problem shortly after doing the guest how-to.

How do I get cgi-wrap and wu-ftpd to co-operate to have users
chroot'ed to their home directories on my apache web server (and no, suexec
didn't work at all), and still be able to run cgi-bins of their own
creation under /home/public_html/cgi-bin. Seems cgi-wrap is a natural
compliment to the chroot idea and they should be compatible.

It would be great if the collective wisdom on the list could bail
me out here. I've got a bit or pressure to get this working yesterday.

Many Thanks,

Fred

OK

Now I really am stumped. Even with this new version of 'ls' in the 'sample'
user's 'bin', the behavior is unchanged: NO Listing of files and
directories that do exist there. GETs PUTs and all other commands function
as desired.

The structures (and permissions) of 'sample' and 'ftp' (for the anonymous)
match. The test ftpaccess file is pretty simple:

# more /usr/local/etc/ftpaccess
class local real,guest,anonymous *.internaldomain 0.0.0.0
class remote real,guest,anonymous *
delete no anonymous,guest
overwrite no anonymous,guest
rename no anonymous,guest
chmod no anonymous,guest
umask no anonymous,guest
path-filter guest /etc/pathmsg ^[-A-Za-z0-9_\.]*$ ^\. ^-
guestgroup client
log transfers anonymous,real,guest inbound,outbound

and, as before, 'ls' functions for anonymous logins but not for this logins
from this guestgroup account.

The debug option (regardless of level) yields no data.

Are you running Kerberos 4 or 5. I think that 4 is built in to
wu-ftpd. I modified it for Kerberos five. We are only using Kerberos
to verify the username and password - the user's home directory is
still being pulled from the password file by the existing wu-ftpd
routines. Let me know if you are running 5 and I'll send you a list
of our changes.

The same thing as "Segmentation fault" in shell. Signal 11 is SIGSEGV.
In other words, something is terribly wrong, and ftpd accessed some memory
that doesn't belong to it or tried to write into readonly one.

Hello Jim,

We are planning to install Kerberos 5 for authentication on our IRIX 5.3
system. I would appreciate if you could send me your changes. Did you
also kerberize rlogin, rsh, telnet etc? I would like to know about your
experiences with this.

Thanks in advance, Luc.

Folks,
I may be interested in Kerberos, Could someone point me to some info
explaining what it is and what functions it provides.

Thanks

First, several things:
1. I'm an old C programmer who is new to UNIX, so while this works, it
may not be the best way to do it.
2. Wu-ftpd was compiled using the SunOS's (5.5.1) cc compiler.
3. We are only using Kerberos to verify username and password, the
user's home directory is still pulled from the password file using the
original wu-ftpd code.

Changes to ftpd.c:
1. Before '#ifdef KERBEROS' (approx line 146), added:
#ifdef OUKRB5
#include <sys/types.h>
#include <k5-int.h>
#endif /* OUKRB5 */

2. Before '#ifdef KERBEROS' (approx line 353), added:
#ifdef OUKRB5
int krb5_authenticate( char *username, char *password );
char krb5_name[ 100 ];
#endif /* OUKRB5 */

3. Before 'askpasswd = 1;' (approx line 1271), added:
#ifdef OUKRB5
strcpy( krb5_name, name );
#endif /* OUKRB5 */

4. Before '#ifdef KERBEROS' (approx line 1418), added:
#ifdef OUKRB5
; /* Do nothing with xpasswd */
#else /* OUKRB5 */

5. Before '#endif' (approx line 1428), added:
#endif

6. Before '/* If authentication from kerberos fails */' (approx line
1434), added:
#ifdef OUKRB5
/* If authentication from kerberos fails */
if ( krb5_authenticate( krb5_name, passwd ) ) {
#else /* OUKRB5 */

7. Before '#endif' (approx line 1438), added:
#endif

8. Before '#ifdef KERBEROS' (approx line 3698), added:
#ifdef OUKRB5
int krb5_authenticate( char *username, char *password )
{
krb5_context kcontext;
krb5_ccache ccache = NULL;
krb5_error_code code;
krb5_principal me, server;
krb5_creds my_creds;
char *client_name;

krb5_init_context( &kcontext );
krb5_init_ets( kcontext );

if ( krb5_cc_default( kcontext, &ccache ) ||
krb5_parse_name( kcontext, username, &me ) ||
krb5_unparse_name( kcontext, me, &client_name ) ||
krb5_cc_initialize( kcontext, ccache, me ) ||
krb5_build_principal_ext
( kcontext, &server,
krb5_princ_realm( kcontext, me )->length,
krb5_princ_realm( kcontext, me )->data,
KRB5_TGS_NAME_SIZE,
KRB5_TGS_NAME,
krb5_princ_realm( kcontext, me )->length,
krb5_princ_realm( kcontext, me )->data,
0 ) )
{
printf( "error when initializing\n" );
exit( 1 );
}

memset( (char *)&my_creds, 0, sizeof( my_creds ) );
my_creds.client = me;
my_creds.server = server;
my_creds.times.starttime = 0;
my_creds.times.endtime = 0;
my_creds.times.renew_till = 0;
code = krb5_get_in_tkt_with_password( kcontext, 0, 0,
NULL, NULL, password,
ccache, &my_creds, 0);
krb5_free_principal( kcontext, server );
return( code );
}

#endif /* OUKRB5 */

The Makefile was modified to define:
LKERB = -lauth -lckrb -lkrb -ldes
And use it for ftpd.

That's all, folk!!
Good Luck

Another possible problem is the day when time( NULL ) returns 0 or a
negative number... It'll happen sometime. Depending on implementation
it'll either be in 2038 or 2106 so we've got some time leway here :), but
it's something to consider, also. Of course I'm not sure that wuftpd can
deal with it without the help of the underlying unix kernel.

3. We are only using Kerberos to verify username and password, the
user's home directory is still pulled from the password file using the
original wu-ftpd code.

It's important to note that this is *only* using Kerberos to verify the
username and password. The Kerberos password is still being sent across
the FTP command channel in the clear, so it's succeptible to
eavesdroppers. As such, you may *not* want to encourage users to use
this.

There is code in the MIT Kerberos V5 distribution which supports client
authentication, where the ftp client uses Kerberos to authenticate, and
then encrypt the ftp connection to the server. This requires a version
of the ftp client and server which supports the GSSAPI authentication
extensions.

It would be possible to move this code into wu-ftpd; it would require
pretty siginificant patches, though. Is this something that Academ
Consulting Services would be willing to see integrated during the 2.5
development cycle?

I am running wu-ftpd on an SGI Indy irix 6.2. I have tried all kinds of
suggestions about how to configure the /etc/passwd file for guest ftp users
and have narrowed it down to the shell. If I use /bin/csh at for the guest
user's shell in /etc/passwd everything is great. The chroot is fine hitting
the right directory and the guest is unable to cd to any other directories
which is the way I want it. However there is a huge security hole here as
the guest user set up in /etc/passwd can telnet or rlogin and get all
around the system. I have tried /dev/null, /bin/false and even /bin/true
listing all in /etc/shells as directed to no avail. the ftp server always
denys the guest user access unless I have set his account up with /bin/csh
as his shell. I have heard about some thing called ftponly. There are some
elusions on the newsgroups that this is a dummy file and I also read where
the source had to be compiled. This looks like the solution but how do I
get the binary (I have no compilers at this time)? I have tried putting an
ftponly dummy file in /etc as directed and also including it in /etc/shells
to no avail. It has also been suggested that one can create a shell to deny
access via telnet or rlogin but to allow ftp access only. Can you shed some
light on this dilemma? Cheers.....JR

Hi.

This is an easy one I guess, but I need some help.

I'm running WUFTPD 2.4 under AIX 4.2

I want real users to be 'chrooted' as if they were
anonymous or guest users.

I've tried with the next entry in <ftpaccess> file:

guestgroup xxx

and real users belong to the group 'xxx'.

The users' home directory is /<dir1>/./

Thanks in advance.

I changed the login shell for some of my users by changing the intry in
the passwd file. Now those users can not login with ftp. I tried to fix
this by changing back to the orginial settings but it still isn't working.
the users that i did not change are not having this problem.

could someone please help?

If you change the login shell, you may have to edit (or create) the /etc/shells file so that the shell will have permissions. The file looks something like this:
/bin/csh
/bin/sh
/bin/bash
/bin/ksh
/usr/bin/tcsh
/usr/lib/uucp/uucico

Until I created this file, anyone with a /usr/bin/tcsh login shell couldn't ftp in.

I did check that file and all of the shells on my system are in it. I
also noticed that when I try to logout I get a "not a login shell use exit"
message. The odd thing is that I also changed the root shell to match the
others and it doesn't have any problems at all.

Maybe a title change will get somebody's attention.

I've been through ftpd.c over and over. I can't see why only one command
'/bin/ls' is broken for the guestgroup. The chroot and chdir obviously
work. And as I have noted in my prior posts, '/bin/ls' is NOT broken for
anonymous or for real users.
____
The parallel discussion thread of various shells under IRIX6.2 seems to be
irrelevant here. I am not seeing any 'type of shell' problems at all no
matter what I use for the guestgroup access.
____

With the debug option on and connecting via ftp client, the messages for the
'ls' command that appear indicate a perfectly normal operation.

But nothing shows up. All messages show connection open, the message 150
ascii transfer, connection closing. And nothing shows up.

------------

Trying via telnet rather than ftp client, I connect to the port, login, give
the password and CWD STOR RETR CDUP and so on all work Except LIST which
gives the 425 message from the source:

425 Can't build data connection: Connection refused.

on trying to list the current directory (or any suitable path).

The only ls-specific difference between anonymous and guestgroup(or real) I
can see is in ftpcmd.y but since the command works for real users I do not
understand why the chrooted version inside the bin directory of the 'sample'
guestuser would clutch up.

Assuming you have installed a ~/bin/ls in the chrooted guest account, ls
in the guest environment is usually broken because it does not have access
to the necessary shared libraries or devices. It is because the chroot
works that the shared libraries in /lib, /usr/lib or wherever are no
longer accessible. If you've not read it yet, this is explained in the
guest howto (below). One solution is a static linked ls if it is an
option for you; you may still need ~/dev files, depending on the platform.

The specifics for this are different for each OS; I've collected a few OS
specifics at the end of the guest howto. Some IRIX configuration data was
added recently.

True; the shells discussion is irrelevant for non operational ls.

Because ls is not running to completion; it can't, as it does not have the
libraries or devices it needs.

If in the process of setting up your site you find additional OS specific
information about the IRIX setup, please email it to me so I can add it to
the guest howto. Thanks,

I have installed WU-FTP and have successfully set up group access. I am
now attempting to set up anonymous logins, but only from a select set of
hosts. So far I have had no luck in limiting the hosts which can access
the ftp server anonymously. Is there a way to configure wuftp to allow
access only to a select group of hosts? If so, could you please give me
some pointers?

Thanks in advance for the help and advice.

'man ftpaccess'

Look at the class directive.

I am having the exact problem where the ls command shows nothing when used
by a guest user. I have solved the problem, sort of. Firstly my /etc/passwd
entry for a guest user looks like this guest:xxxxxxxx:guest ftp
user:~ftp/user/guest:/bin/csh. In this config it seems to work however it
leaves a huge security hole as the guest ftp user can telnet into the host
machine. If I enter the /etc/passwd as follows the guest user is chrooted
into the directory guest but the problem of no list coming up occurs.
guest:xxxxxxxx:guest ftp user:~ftp/user/./guest:/bin/csh. I noted that you
were using irix version 5.3 and I know that with 6.2 if you check the man
page for ftpd there is some good info on how to make the "ls" work for
anonymous users which seemed to solve a lot of my problems except with the
dreaded "guest user". I know this is probably more confusing than help but
I tried. Cheers.....JR

guest:*:guest ftp user:~ftp/user/./guest:/etc/ftponly

Use a single x or * as the password and you can lock the account from
login. This may vary system to system; check yours specifically. I think
the shadow password system wants a single x. Also, use a non existent or
non executable shell, such as the dummy entry /etc/ftponly, and you should
be okay.

Did you ever get an answer on this?

Sounds like a source hack is in order on cgi-wrap to get it to swallow the
/./ in the /etc/passwd home path.

Yet, something is still not adding up as I understand your description so
far. When you chroot the user in ftp to upload the CGI stuff, the CGI is
not executed at that time. The cgi-wrap is executed later from the Web
server, no? What does a chrooted ftp session have to do with Web server
CGI? Are they running the CGI programs from the ftp login?
