True, *read the Irix updated in the guest Howto!*
Especially the /dev/zero (and /lib/...) files, will be of help to you.
Without these, I had this 'blindfolded-visitor' sensation. Interesting, but not
really helpful indeed.

Maybe a redundant remark; but important enough to underline to Irix users,
concerning the 'shell'.
Best is IMHO to use a fake shell /bin/false & /bin/true i.o. /bin/csh.
Other 'shells' maybe used of course, but in any case THE SHELL MENTIONED MUST
BE STATED IN '/etc/shells'. If not, the ftpd will disallow ftp access, too.
(Which maybe helpful in some cases)
In the case of /bin/true and/bin/false, you can decide who has 'ftp access, but
no shell possibillity' or 'no ftp, access, and no shell (thus: NOTHING)
access'.
This maybe your answer for a possible security breach.
An example of the bin & false files mentioned:
/bin/true:

Sorry for the stupid question but I am running wu-ftpd on an IRIX 6.2
system and have tried using both of these shells you mentioned also listing
them in a directory called /etc/shells. Is this the source code for these
shells that you have included? Cheers....JR

No, its not that the cgi's are executed when the chroot takes
place, but, since cgiwrap derrives its paths from the home dir indicated in
/etc/passwd, it was translating the path to the cgi to be something like
this;
/home/joeuser/./public_html/cgi-bin/sample.pl, , an illegal
path which casued the cgiwrap error, instead of
/home/joeuser/public_html/cgi-cin/sample.pl
Now I have the same problem, even after the hack, with my virtual
domains (also chrooted) that have this path translation problem. I've
posted to the cgiwrap list concerning that one, but its not resolved yet.

X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Dear WUFTPD'ers,
Had been planning on using NFS in conjunction with WUFTPD in order
to share some file systems between servers. But a number of people
expressed concern over numerous NFS security issues. AFS was
suggested as one alternative. I am curious though what other people have
found to be the best file sharing systems, and if WUFTPD works better
with any of them.
Thanks in advance,

Not stupid at all! Anyway, the shells mentioned (or any shell for that matter)
goes in /bin. The _names_ of valid shells go in the _file_ /etc/shells.:
for example:
> less /etc/shells
/bin/sh
/bin/csh
/usr/bin/ksh
/usr/bin/sh5
/bin/true
/bin/tcsh
/usr/local/bin/tcsh
---
NOTE that /bin/false should NOT be in there.
Feel free to ask if anything still isn't clear (including me:))

I was under the impression that using /bin/false as a shell would
limit the user to only ftp commands and not let them do site exec
type things etc. I also thought /bin/false should go in the
etc/shells, but I guess I'm mistaken. What is the proper way to use
/bin/false.
thanks in advance

I am running FTP server wu-2.4 on an AIX 3.2.5
I need some advise on using the path filter. We have some guest
accounts (about 90% of our accounts) that we want to only put file with
the names trsrpa, trspost, and trsny. We can set this up with the path
filter, but the other guest accounts could upload any file names. How
do I keep these from coming under the same restrictions.
thanks

Subject: Allowing deletes in /pub

I'm new at this and am trying to set up an anonymous ftp site where any
user can read, write or delete files and directories in the /pub area. In
order to allow deletes, I put the following line in the ftpaccess file:
delete yes guest,anonymous
This enabled the anonymous user to not only delete files in /pub, but also
any other file or directory in the ~ftp area including /bin, /incoming,
welcome.msg and so on. Permission bit settings were ineffective at
preventing the deletes. Is this to be expected? If so, how can I
accomplish what I want? That is, /pub is completely open and everything
else is locked up for anonymous users.
Thanks,

Subject: Re: Static-ls
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Hello!
I used the static-ls patch, posted here the other day, along with fileutils3.16 as suggested
and it works, except for 1 thing. I use NIS+, and the static-ls patch assumes "/etc/passwd" as
the source for UID's. Does anyone know where to get a statically linked 'ls' (or source code)
that supports NIS+ (ie, uses getpwnam instead of scanning the /etc/passwd file) ?
Thanks,

Hello, I just wondered one thing .. you want to look up uid->NIS+-login,
right?
But then why don't you copy the needed libraries to ~ftp/usr/lib and the
systems ls to ~ftp/bin ?? That (shared) version should have the
possibility to check NIS+users (if you got some special files in
~ftp/etc)
. but a static version of ls with NIS+ check builtin might be
some problem .. because what we did to make the static ls was to create or
own caching of getpwnam (or similar) .. you've got to add checks to
weither NIS (YP) or NIS+ is what you use .. where to get the info
requested and the lots .. But if someone got the time .. do it .. :-)

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

I compiled the new beta 13 today, without any problems...except
that virtual ftp wont work correctly. I followed the instructions ive
seen on usenet, and in the VIRTUAL.FTP.SUPPORT file, to no avail. Its
almost like the /etc/ftpaccess file is getting ignore ( i have it in
/etc/ftpd/ftpaccess as well)
Has this been discussed as of yet? If so, I apologize in advance for
asking a repeat question. But, if that is the case,can someone direct me to
the archives?

Mark,
Have you used the -a flag in the command line that starts the daemon. I dont
know beta 13 but unless something has changed you need the -a flag to invoke
parsing of the ftpaccess file (or you can hack the source and hardcode it -
although I know no good reason why)

Deletes are a function of directory permissions, not file permissions. If
the anonymous users have write access to the directories themselves, they
can delete files in those directories, regardless of permissions or

Subject: Using GNU BISON instead of 'yacc'.
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Hi.
I'm compiling WUFTPD 2.4.2 Beta for AIX 4.1.4 and then for
AIX 4.2
I need to use GNU BISON parser instead of 'yacc'.
I got GNU BISON installed, but I don't know how to use it
instead of 'yacc' while compiling.
Any idea?
Thanks.

Subject: More help. GNU BISON.
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Hi there.
Thank you very much for helping me!
But I need more help.
Let me explain:
I'm compiling WUFTPD 2.4.2 Beta for AIX 4.x
I've installed GNU BISON.
The next step is './build aix'. Here it fails.
These are the error codes:
ld: 0711-317 ERROR: Undefined symbol: .snprintf
ld: 0711-317 ERROR: Undefined symbol: .vsnprintf
Is it because of 'yacc'?
I haven't found where to change 'yacc' for 'bison -y'?
Perhaps there is no need to change 'yacc' and these errors are due
to something else.
The other commands (ftpwho, ftpshut, ...) are well compiled.
Here it is.
Thanks again.
Moises Navarro Marin.

no, I don't know AIX but it looks like the loader
doesn't find snprintf().
can you do
man snprintf ?
if not version BETA-13 provides a very limited
implementation written by Patrick Powell
support/snprintf.c
link ftpd with it. Surprising that the config file didn't take
care of that. Mr Barber does a very good job in does things...
Are you using the right config file ? config.aix
I also find very suprising that AIX doesn't have a
decent version of yacc.
>

***** Off Topic ****
For those interested, I've written a full implementation of
snprintf, that can do floating point calculation. I needed
to shut some buffer overrun holes. Most free implementtion
find on the Net don't do floating point, and the one
that does are not portable :-(. So I sat down one day.
It should run on all platforms.

Mr. Barber *does* an excellent job of things. Very responsive to reports of
human errors or bugs.
> I also find very suprising that AIX doesn't have a

I'm working with the original poster to resolve this issue on my own
without spending extra time on the list for this. Email me if you (whoever)
have a similar problem and wants to know how to fix.
FWIW, wu-ftpd compiles out of the box flawlessly (now, at least ;-) ) for
AIX 4.2 and 4.1.4 machines we have here, using IBM cc.

Maybe I'm going about this all wrong....
I have a client with an anon ftp site.
We'd like to set up directories under the pub folder for specific
clients...password protected.
The site will be accessed via Netscape, so the sitexec thing is
inappropriate, and
they need to upload...
(Not to even mention WAY to complicated for these dolts!)
The guest group won't work, and I get the feeling it is because the FTP
site is devoted to them and not the original anon ftp owner.
What are the left over options?

Under Solaris 2.x getpwnam() can't be used without dynamic linking. From
getpwnam(3C):-
Programs that use the interfaces described in this manual
page cannot be linked statically since, the implementations
of these functions employ dynamic loading and linking of
shared objects at run time.

I installed several months and am just now getting around to trying to
fix a problem. I have guests logging in to virtual servers and I would
like to log-in myself without the restrictions. I am in a diff group
than the guest group, yet the only way I can log-in is if I make my home
directory the root directory. If I set my home directory to anything
else (Like /usr/home/thom) I get an error that the directory does not
exist, and then an error "Can't create datasocket". I'm sure that I am
just an edit away. A suggestion or a shove in the right direction will be
appreciated.

I have now built from 2 different wu-distributions, one older that I had to
hack around to get the make; one the newest Beta-13. The 'ls' behavior is
identical no matter what for guestgroup (as I said before, real and
anonymous work). Since I also built the 'ls' in the bin from the GNU
fileutils as expressly non-shared.
[as provable via: strings -a bin/ls | grep \\.so yielding nothing]
I have run the tests with debug set in client line and the -d flag on the
daemon in the inetd.conf. (also -a -L -l). The excerpted transaction

Unfortunately, I cannot report any guestgroup 'ls' success in spite of these

I am trying to set up a guestgroup in wu-ftp, running on an alpha with
RedHat4.1 by following the FAQ at
ftp://ftp.fni.com/pub/wu-ftpd/guest-howto. When it is all set up I can
log in successfully and GET files, but when I try to put files, I get
this error:
Password required for test.
User test logged in. Access restrictions apply.
> put formmail.cgi
Error: Remote host has closed the connection.
The permissions on the how directory are as follows:
drwxr-xr-x 4 test test 1024 Apr 3 09:39 .
drwxrwxr-x 71 root root 2048 Apr 2 16:47 ..

d--x--x--x 2 root root 1024 Apr 3 09:41 etc
-rw-r--r-- 1 root test 1873 Nov 20 16:32 test.htm
The password file looks like this:
root:*:0:0::/:/bin/false
test:*:268:2000::/usr/local/apache/htdocs/users/test/./:/bin/false
And the group file looks like this:
root::0:root
wwwftp2::2000:test
What is going wrong here?

Why don't my posting show up in this list? This is my third attempt.
I installed several months and am just now getting around to trying to
fix a problem. I have guests logging in to virtual servers and I would
like to log-in myself without the restrictions. I am in a diff group
than the guest group, yet the only way I can log-in is if I make my home
directory the root directory. If I set my home directory to anything
else (Like /usr/home/thom) I get an error that the directory does not
exist, and then an error "Can't create datasocket". I'm sure that I am
just an edit away. A suggestion or a shove in the right direction will be
appreciated.

The problem turned out to be due to the fact that beta 13 for AIX had
a slight error in support/makefiles/Makefile.aix, in the OBJS line.
All object files were listed (ie .o) but snprintf was listed as
snprintf.c. Changing that to snprintf.o and doing a build clean, then
build aix takes care of the problem.
Stan Barber fixed that problem within 60 seconds of notification, so it
shouldn't be present in future releases... I don't think it existed in
previous betas, FWIW.

Why not just provide a skeleton copy of pw info by running, at your

I'm having trouble getting the upload directive in ftpaccess to change the
owner and group of uploaded files.
I'm running wu-2.4.2-academ[BETA-13] on Solaris 2.5.1. I've successfully
created a guest account (guest1) with it's own chroot area. I've got the
following entrys in ftpaccess:
upload /opt/guest1/ /pub yes root other 0600 dirs
However, when a user logs in as guest1 and uploads a file to the /pub
directory, it comes in owned by guest1.
What am I doing wrong?

Jeff,
Bless you!
Using your tar file of GNU fileutils-3.16 and the native IRIX 6.2 compiler
with the -non_shared option did the trick. After 4 months of trying and
countless
hours spent talking to SGI, I finally have a static ls version that works
on
IRIX 6.2.
But I still dont have a clue what /usr/lib/ldstatic is and why my build
attempts
with fileutils-3.13 and native compiler kept asking for it. Was that a
virgin
fileutils-3.16 tree you delivered to me or had you already made some
changes to it? I would like to understand why this suddenly succeeded so
I can feel comfortable that I could do it again with a different version
someday if necessary.
Thanks again,
Roger Hanke

I loaded the non shared stuff onto my machine today. Here is what was
loaded
I c_dev.sw.speclib 04/01/97 C NonShared Libraries for Benchmarks
I compiler_dev.sw.speclib 04/01/97 Base Compiler NonShared Libraries for
Benchmarks
I dev.sw.irix_speclibs 04/01/97 IRIX NonShared Libraries for Benchmarks
I dev.sw32.nonshared_lib 04/01/97 NonShared N32 Libraries
I dev.sw64.nonshared_lib 04/01/97 NonShared N64 Libraries
I ran configure with non arguements on fileutils-3.16.
I edited the Makefiles in lib, intl, and src directories to add
-non_shared
to the CFLAGS and LDFLAGS lines (if they existed).
After compilation I get
[121] [azure] tohanson/fileutils-3.16/src >file ls
ls: ELF 64-bit MSB mips-4 executable (not stripped) MIPS -
version 1
[122] [azure] tohanson/fileutils-3.16/src >file /bin/ls
/bin/ls: ELF 32-bit MSB mips-2 dynamic executable MIPS - version 1
Azure is an R8000 based computer which is why it uses mips-4. I leave
it to you to try -n32 or -32 as you need. You'll find the whole message
in a tar file (source only unless you want otherwise) at
ftp://ftp.lerc.nasa.gov/users/tohanson/fileutils-3.16.nonshared.IRIX6.2.
tar.gz
Let me know how it goes.

I'm having a major problem.
I'm running wu-ftpd-beta 11 with virtual anon ftp sites.
It's been running FINE for about 8 months.
I just added a user and he's been going nuts with the msg files and
directories.
Now anon doesn't work when anyone goes to any? site...ftp is acting rEAL
flakey now.
I get the message...Sorry, the connection has been dropped, the server may
be too busy.
The strange thing is...it happens AFTER the password is given.
Connected to novakdesign.com.

Hi...
I just down loaded (is this the latest and greatest version?):
wu-ftpd-2.4.tar.Z
and I'm having some problems compiling it for HPUX. the compile seems
to fail at:
cc: "realpath.c", line 45: error 1711: Inconsistent parameter list
declaration for "realpath".
Here's the declaration in ftpd.c:
extern char *getline(),*realpath(char *pathname, char *result);
If I change the declaration to:
extern char *getline(),*realpath();
it works, but then fails at the function defention:
cc: "realpath.c", line 45: error 1711: Inconsistent parameter list
declaration for "realpath".
I'd appreciate any help ASAP. =)
Thanks,
jeremy

Nope. Get the beta-13.

The difference is in the header files. Your wu is expecting the variable
argument of varargs.h version. The one on your path is probably the
stdlib.h version.

The beta-13 may have enough new branches to take care of this for you, but I
don't know about the specific HP-case.
If you want to work with what you have, check for nested includes. My bet
would be you need to fix syslog.h and stdlib.h to get your version to make.

I have no clue as to what /usr/lib/ldstatic is, nor does it exist on the
6.2 machine that I built things with. All I did to the fileutils was
to run configure and place -non_shared in the Makefiles for LDFLAGS and
CFLAGS. This should continue to work with new versions of fileutils
since it worked for 3.12 which is what ftp.lerc.nasa.gov uses. How
long SGI will continue to make the speclib things available for
building static objects I don't know so I can't speculate on anything
after the MIPSpro 7.1 release (which stil has it, having just loaded
the compilers on my O2 running 6.3).

Jeff--
As my lengthy last post(Re: Guestgroup &this topic) shows, I still
haven't got the IP19 IRIX5.3 to see the static 'ls'. In trying same with
3.16, I am already getting
/usr/bin/../lib/ld:
Object file format error in: /usr/lib/crt1.o: shared Elf object
"/usr/lib/crt1.o" cannot be linked non-shared.
*** Error code 1 (bu21)
which I'm sure I'll solve one at a time as always.
Probably IRIX-specific peculiarities from 5.3,6.2,6.3 (that I oversee)
will fluctuate all over the map relative to applications and show up in the
newsgroups, but one would think some of the better hotshots there would at
least read this list since I have had, daemon-by-daemon, to rebuild almost
everything that ships out of the box in primitive insecure form.
If the next round of upgrade (with, acc.to.mktg. Everything being
perfect in 6.5) leaves as many holes and out-of-date implementations, I
would suggest IRIX users unionize and demand better tools.

We intend to revise the authentication sequence in 2.5, so consideration of
kerb5 is certainly something on the list.
However, I am very attracted to the "plug-in" approach to doing this. I have
investigated some of these new mechanisms and like what I am seeing do far.

I also had this problem. You can fix it by changing the root line. Make the two lines look like this:
upload /opt/guest1/ * no root other 0600 dirs
upload /opt/guest1/ /pub yes root other 0600 dirs

I for one find your question unclear. It also seems to show a basic lack
of understanding about FTP logins and Unix permissions in general. Not to
be cold, but few have time to explain Unix basics for a daemon that
already requires a good understanding to set up. If you don't have the
basics down and can't set up a secure ftp server, you may be setting
yourself up for a hack.

What restrictions? Guest restrictions? Permission/access permissions?
What do you want to be able to do?
If you want to be able to log in as an effective "superuser" over your
virtual users and do anything you want, you will have to understand
permissions and ownership and set all files and directories appropriately.
If you are a different user in a different group, then you cannot do
anything you want without setting everything world read/writeable. For
fairly obvious reasons one would not want to do that.

Is this a real login (not chrooted guest)? You did not say, but it is
important. If it is a 'real user' login, it should work; if not, you are
missing something fundamental in your system structure. Go over the howto
and make sure that all required libs and devices exist for your system. If
this is a guest login and /usr/home/thom does not have the proper
directory structures, it may well fail like this. But you knew that.

Sorry, I was trying to be brief because I hate long e-mails and I made
several assumptions. Let me elaborate.
I have wuftpd compiled to handle virtual servers, using "/./" at the end
of each guest's home directory to invoke the chroot. Guest users are
group "users" as defined in /etc/ftpaccess. I am a member of that group
and I am also a member of serval other groups. What I am trying to do is
define my home directory in /etc/passwd so when I telnet in I have my
shell set up like I like it. The problem involves wuftpd because when I
have my home directory set in /etc/passwd, I get the errors when I try to
FTP in. The only way I can successfully FTP to the box (and have access
to the entire box) is if I set my home directory to the machine root.
I hope this help and I appreciate the responce Michael.
Anything else and I get the errors. Is this addressed in the howto you
reference? Where is this howto?

Hi
Did this happen when you added another user if so check the ftpaccess
file.
In the sectio with guestgroup and all the users listed on one line
e.g guestgroup name1 name2 name3 etc etc make sure that you do not have
over 30 ish users in one section. I think the limit is about 50 but I am
not sure, so stick with 30ish.
If there is motre just start another line with guestgroup and add the
last user there.
Let me know if this works
Iqbal

Hi
I have managed to install a working copy of wuftpd. Everything seems to
be working fine. There is one thging, I need to install cgi-wrap now,
and I just want to check if cgi-wrap will work with wu-ftpd(or is this a
stupid question). I have posted theis to both cgi-wrap list and wu-ftpd,
just in case someone has done this before.
Thanks

Hello,
I'm trying to use the "guestgroup" feature of wu-ftpd on AIX 4.1.4.1
I've downloaded a precompiled version of wu-ftpd (2.4[5]) from
www.bull.de/pub/ since I don't have the IBM compiler and cannot compile
the latest version by myself.
Here is my configuration :
/etc/passwd :
-------------
user1:!:300:300::/ftp/user1/./user1:
/etc/group :
------------
customer:!:300:user1
/usr/local/etc/ftpaccess :
--------------------------
class all real,guest,anonymous *
guestgroup customer
# how to check password? Use "enforce" instead of warn to refuse access
passwd-check rfc822 warn
# command logging goes to syslog,
# transfer logging goes to /var/adm/ftpd/xferlog (use xferstats to
display)
log commands real,guest,anonymous
log transfers anonymous,real,guest inbound,outbound
In the /ftp/user1 directory :
-----------------------------
d--x--s--x 2 root system 512 Apr 4 16:58 bin

If I run ckconfig, everything seems to be okay.
Here is the problem :
---------------------
# ftp beethoven.rever.fr
Connected to beethoven.rever.fr.

^^^^^^^^^^^^^^^^^^^^^^^^^^
My questions :
--------------
Why do I get this error message ?
Where can I download the latest version of wu-ftpd precompiled for AIX ?
Is it possible to compile the program with gnu gcc ?
Thanks,
Patrick Buseine

Only incompatibility is with chroot()'ing with the "/./" in the user's home
dir.
If you make the minor patch of removing that check in util.c, you'll be all
set.

Hi
If I remove that check, it won't have any affect on wu-ftpd security
thing, since they are separate processes.
One other thing, is cgi-wrap, the same as setting SUID/SGID on the
script, if so does it SGID or SUID or both. I would like it just to SGID
Thanks

Thank you very much in advance,

After a bit of digging, I think I have found the reason for the dropped
connections.
The following is an excerpt from
ftp.fwi.uva.nl/pub/solaris/solaris2.html:
"5.17) TCP/IP connections time out too soon, especially on slow links.
The tcp/ip abort interval in Solaris 2.x is too short, the default value
is 2 minutes. The result is that when an ACK isn't received in 2
minutes, the connection is
closed. This is most often seen by sendmail, which will log
sendmail: SYSERR: collect: read timeout on connection from ...
You can fix this by running following command which increases the
timeout to 8 minutes (unit is millisec), which is the Solaris 2.4+ (and
patched 2.3) default.
/usr/sbin/ndd -set /dev/tcp tcp_ip_abort_interval 480000"
Fine, it talks about sendmail but tcp is tcp is tcp, yes? Yes.

Sounds interesting.
Anyone happen to know if something similar might happen in
AIX, and what the corresponding AIX network option might be?

all i can say is "thank you" for expressing my opinions exactly. the s/n
on this list is considerably lower than it should be because of neophytes
who don't know the basics of unix config and who don't read the faqs.

so if I add an include varargs.h to realpath.c, will that fix the

As a dyed in the wool IRIX fan, I must take some exception to your
characterization of IRIX but I do sympathize with your problems not
getting the support that you need.
Enclosed are my instructions for building a static ls under IRIX 5.3
and 6.2. I'll send 6.3 instructions tomorrow after I get my O2 online
today (assuming all goes well).
You can get source modified as detailed as
ftp://ftp.lerc.nasa.gov/users/tohanson/fileutils-3.16.nonshared.IRIX5.3.tar.gz
or
ftp://ftp.lerc.nasa.gov/users/tohanson/fileutils-3.16.nonshared.IRIX6.2.tar.gz
Prebuilt ls are also available (remember to chmod 111 ls once retrieve).
IRIX5.3 built on IP7
ftp://ftp.lerc.nasa.gov/users/tohanson/gnuls.nonshared.5.3 or
IRIX6.2 built on IP21
ftp://ftp.lerc.nasa.gov/users/tohanson/gnuls.nonshared.6.2
Standard disclaimers about my responsibilty for what you do with these
files applies!

dev.sw.irix_speclibs IRIX NonShared Libraries for Benchmarks
3. Use configure to create the IRIX version of the Makefiles.
4. Make the following changes to src/Makefile, lib/Makefile and intl/Makefile
Add -non_shared to each CFLAGS = line
Add -non_shared to each LDFLAGS = line
Remove -lsun

I'm running the latest beta of wu-ftp and am having a wierd error
with a guest account. Any uploaded file that has a long filename or a
space in the filename is getting the error 'Permission denied. (Filename
(accept))'. This is only with a guest account. As far as I can tell my
guest account is set up correctly and besides this error, its working
fine. Any ideas?

If the client end is a Win95 box with an old 16 bit FTP program, then long
file names will be collapsed with a ~ in the name. By default, both space
and tilde are not allowed in filenames. Look at the path_filter in
/etc/ftpaccess.
man ftpaccess
for more info.

However, I am very attracted to the "plug-in" approach to doing
this. I have investigated some of these new mechanisms and like what
I am seeing do far.
Can you say more about the "plug-in" approach? What sort of mechanisms
are you investigating?

I do have some sympathy with this point of view. But - one of the problems
is that many of the neophytes son't know about the FAQ's, or where they are.
The 2.4 distribution I have doesn't mention them in the README or INSTALL
files, although it does mention this mailing list. Admittedly, this
version is a bit old in the tooth and perhaps the FAQs didn't exist then -
the beta 11-13 documentation may mention them (Stan ?).
If not, then any neohpyte looking for help who subscribes to this list
typically has to wait until Michael or Koos (or occasionally someone else)
makes a posting that references the FAQs in order to find out about them.
I think it might help if the mailing list server could add a few lines at
the bottom of every message to list the locations of some of the most useful
FAQs. Say, Koos' FAQ (
http://www.cetis.hvu.nl/~koos/wu-ftpd-faq.html),
guest how-to (
ftp://ftp.fni.com/pub/wu-ftpd/guest-howto), Kent's virtual
server FAQ (
http://www.landfield.com/wu-ftpd/virtual-ftp-faq.html) and
perhaps Paradise Cowgirl's Solaris 2 FAQ
(
http://www.teleport.com/~minerva/wu-ftpd/wuftpd.shtml).
It might also be worth mentioning one or two of the mailing list archives;
Kent has one at
http://www.landfield.com/wu-ftpd/mail-archive/.
This way, at the expense of a few lines at the bottom (which could be ignored
by folks who already know where the FAQs are), any posting to the list would
hopefully encourage the neophyte to check out these references before
posting their own question...
And putting the same info in the standard "welcome to the mailing list,
here's how to unsubscribe" message wouldn't hurt either.
Would this be acceptable to list members ? Can the list server accomodate
this (I know majordomo can) ?
Cheers, Bob

This "neophyte" does know the basics of Unix and has read the faq but did
not think I need to impress you with that knowledge. I actually thought
you would have enough knowledge to decifer my problem without telling you
I know how to set file permissions. Since you claim to be such an
expert, I certainly hope you will find my elaborations (in subsiquent
posts) about my situation enough information to offer a suggestion or
remedy. I look forward to your solution.

I need to setup a seperate FTPD that does the following:
- Uses an alternate file to authticate (not /etc/passwd)
- If possible limits the amount disk space the user can use
- If possible, runs script after login.
Any suggestions woul dbe greatly appreciated.

Tyler,
I had the same exact questions. I'll include some of the responses I
got. But I ended up changing the ftpd code to make the calls to a
database for lookup because I am not running on linux which from what
I understand support the PAM stuff included below. The second thing
about running a program after ftp is done can be done nicely with the
tcp wrappers info included below. I ended up simply writing a shell
script which called ftp from within it and then when ftp returned I
finished up doing some stuff with the rest of the shell script. Hope
this helps

Use tcpwrappers with TWIST. Send lines beginning with 220 to standard out
(see ftp protocol rfc for syntax details.) Tcpwrappers can be found at
purdue, somewhere. Pointer at

The interface is supposed to handle any sort of authentication of any
combination of authentication modules.
The pam modules I know of do:
/etc/passwd
/etc/securetty
rhosts
Skey
something for shadow passwords
There are at least half a dozen others, chase the pam link somewhere at
http://www.redhat.com. Worse case, you'd have to write your own pam
module. It should be easy to modify an existing one.

X-Mailer: XEmacs 19.13 Lucid

Howdy, folks! I could use some help.
I've got a wu-ftpd server that's been in service for years, and
recently went to wu-2.4.2-academ[BETA-13]. I don't think my problem
is particularly related to the upgrade, but I suppose it could be.
This server is running SunOS 4.1.3.
Suddenly today, anonymous users cannot upload anything. They can try,
and the file is opened, but then:
ftp> cd incoming
250 CWD command successful.
ftp> bin
200 Type set to I.
ftp> put dorothy.jpg
200 PORT command successful.
550 fchown: Not owner.
..and what's left is a zero-byte file, with what appears to be the
correct user and group ownership. I've looked at my passwd and group
files, as well as my ftpaccess, etc., and cannot find the problem, or
even anything that has changed recently enough to be a likely cause
for this problem. I've checked the NIS passwd and group maps, and
didn't find anything wrong there, although that is where I thought I
might, since the maps change often, and might cause a rather sudden
problem like this. I DON'T want to tear the server down and start
from scratch, if it can be helped!
Ideas and suggestions are solicited. I've looked at the FAQ yet
again, but it's *always* possible that I've missed something...
Thanks!

without much thoughts, I see two reasons
1-
Your server is not running as root
check inetd.conf
2-
uid and gid specify in ftpaccess are wrong
Are you loggin anonymous ?

It says:
ftp stream tcp nowait root /usr/local/etc/ftpd ftpd -a
That hasn't changed recently, by the way.
> 2-

I've changed them several times today because of this problem, but
currently, they are:
upload /u/ftp /incoming yes ftp guest
> Are you loggin anonymous ?
Am I... you mean, now? No, but I can do it at any time for testing
purposes! What would you like me to try?

I said it was SunOS 4.1.3.
and the upload line in ftpaccess
Please see above.

Ha ! za mystery ! lets investigate
We assume the server runs as root and
it's compile with UPLOAD enable
The only place ftpd is doing
and fchown() is here. when storing('put' command for the client)
.
oldid = geteuid();
....
(void) seteuid((uid_t) 0);
if ((fchown(fdout, uid, gid)) < 0) {
(void) seteuid(oldid);
enable_signaling(); /* we can allow signals once again: kinch */
perror_reply(550, "fchown");
return;
}
(void) seteuid(oldid);
..
#endif /* UPLOAD */
And you say that the error string was:
> > > 550 fchown: Not owner.
Looking at the <sys/errno.h>:
#define EPERM 1 /* Not owner */
man fchown
..
EPERM The user ID specified by owner is not
the current owner ID of the file
The group ID specified by group is not
the current group ID of the file and is
not in the process' supplementary group
IDs, and the effective user ID is not
the super-user.
so conclusions:
1-
(void) seteuid((uid_t) 0);
failed !!!
2-
fchown(fdout, uid, gid)
failed !!
3-
??? someone else ???
is pub/incoming exported(nfs/afs/rfs) ?
maybe it's how you import/export pub/incoming
One way to confirm this theory is to trace the server
loggin as anonymous (ftp -d localhost)
find the pid of the ftpd server(ps -auxww|grep ftpd)
trace the system calls (trace -p ftp.pid)
on the client:
ftp> cd incoming
ftp> put juliette.romeo
see if the seteuid() or fchown() failed(return -1)
later, goodnight

I successfully compiled and started the wu-ftp daemon, and tested it to make sure it was working (it was mostly). I then ran the ftpshut command (to make sure it worked) and now I cannot restart wu-ftp. The standard ftp that comes with Solaris 2.5.1 works fine when I put it back in the inetd.conf file, but whenever I try to use wu-ftp in the inetd.conf file I get the error that the service is not started, please try again later. The same thing happens if I try to run it from the command line.
I cannot seem to find anywhere in the documentation (or FAQs) anything that states how to actually start up the server, or anything that says running ftpshut will prevent it from running again.
I should mention that since running ftpshut I have rebooted and rebuilt and reinstalled the wu-ftp distribution. I still can't start it.
Any help appreciated.

Bingo. ftpshut creates a message file in /etc that you need to remove. I
haven't used that for a long time, but I think it may be called
/etc/shutmsg. Check for something like that and nuke it.

wu-ftp is working well but when the users use ws-ftp (win95) and connect to
the remote host, it doesn't show the list of files and
directories. This happens only if I put the options -a and -L in inetd.conf
ftp line. I changed the windows MTU stack to 576 (recommended) but it
didn't work either, even if I use Unix ou Sun Solaris in Host Type.
Everything in Unix seems to be ok.
Does anybody have an idea of what's happening?
Thanks in advance.

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

I have not been able to find this information in the docs or FAQs so:
(system: Solaris 2.5.1, wu-ftpd 2.4(2))
Where/what exactly do I need for the pid file? What should the pathnames.h entry be set to and what file/directory needs to exist on disk, with what permissions to avoid the 'open of pid file failed: No such file or directory' message in the log?
Why do ftpcount, ftpwho, etc return 0 for everything? I've tried various settings in the ftpusers, ftpaccess, etc files and nothing seems to have any effect (and I do have an active ftp session when I check the counts).
Other than those two problems, everything seems to be working okay.
Thanks
Colin Young

I am trying to set up a Solaris 2.5 system using wu-ftpd-2.4.2-beta-13
to provide a restricted-ftp service; that is, a 'guest' userid which is
chrooted and behaves like anonymous ftp. I'm sure this used to work under
Solaris 2.4; under 2.5 you can cd to directories higher than the chrooted one.
I have also tried to provide a 'guest' directory under the normal anon ftp
service using SITE GROUP and SITE GPASS, but it seems to take no notice of my
/etc/ftpgroups file; SITE GROUP recognises the entries but doesn;t ask for
a password although I have an encrypted password entry in the /etc/ftpgroups
file as specified.
Has anyone else upgraded a Solaris 2.4 service to 2.5 and a) found it stopped
working and b) fixed it?

Hi
Just run /bin/ckconfig
and you will see where ftpd wants to store pid files.
Just create this directory.
I also have encountered this problem.
Now it is Ok.

Did you take a look at the guesthowto ?
it's rather complete.
Unfortunately I don't remember the URL :(
But it's in the FAQ, and the author Michael usually
read this list maybe, he can send it ... once more (Michael ?)

for SITE GROUP and SITE GPASS to take effect you must specified
in ftpaccess the directive:
private yes
and I believe with beta-1x's, you must at compilation(#undef NO_PRIVATE)
for this feature to take effect.
use ckconfig to see if the path is accesible to the server.

I don't thing that the server will ask specifically for a passwd
it will probably say something like
220 group accepted
and it's up to you to send a
SITE GPASS xxxx
if the passwd is accepted then setegid() is done
If you only have one or two groups maybe
the autogroup directive(man ftpaccess) will be usefull
The setegid() is done automatically for certain type of clients
so no more site group/gpass

Not sure if this is on topic or not, but would love some input.
There seems to be a limitation with Linux's inetd and wu.ftpd which
prevents a server from handling heavy loads. On servers with high
connection rates (i.e., a high volume of clients trying to connect to
the server at the same time), Linux would stop accepting connections and
just sit there. This is probably due to a limitation in inetd more than
anything in wu.ftpd, however, if wu.ftpd could run as a daemon, then this
may not be an issue?
Anyway, I am sure there are people who run loaded servers on Linux with
wu.ftpd, and if there is a hack or something that makes it work, I'd love
to hear about it.
Thanks!
Dennis

It's not a bug, it's a feature.
inetd allows you to specify how many connections per minute will
be allowed for a specific service. The default value is just way
too low for a heavy loaded system (I think, less than one per
second).
You can define the maximum connections per minute in the <flags>
field, separated from the wait/nowait parameter with a dot.
For example
ftp stream tcp nowait.256 root /usr/sbin/ftpd ftpd -a
will allow 256 ftp connections to be started within a minute.
I'm not shure whether there's an upper limit to the count.
Alex.

It's a configurable feature in inetd. man inetd

I've got a person using a windows-based FTP client that can't see the
list of files in a directory. She has used Chameleon and WS-FTP, same
problem. Given a filename, she can download a file.
I've checked directory and file permissions, and they appear OK.
She does log in as a guest user.
Any ideas?

Did you check the copy of ls you created under the ~ftp/bin directory?
Perhaps the permissions on that aren't set properly or you have a bad copy
of ls -- or it isn't even there.

Hello,
I hope I understood your question. Here goes...
I have set up something similar to what you've described as a "guest" ftp
account under Solaris 2.5.1. I did not, however, use the /etc/ftpgroup feature
like you've mentioned. I created an ftponly user id with the ftponly group id,
and utilize the "guestgroup" feature of ftpaccess. This ftpguest user is
dropped into ~ftp/pub upon login, and about the only directories he/she can cd
into are the chroot /, pub, and incoming (see the cdpath entries in my
/etc/ftpaccess below).
Here's a shortened capture of some of our files:
/etc/passwd:
------------

So uploading does not work without the ~/etc, ~/bin and ~/dev directories
in each guest account? I've never seen this. Can anyone else on the list
verify this? I just don't have time now.
I use a perl script to build all my guest accounts so all the clumse is
hidden. I use a statically linked ls that does not need ~/lib, and ~/dev
is not needed on my OS, so I only have ~/bin and ~/etc. I use hard
(inode) links from each guest account back to a single master copy of ls
or whatever other utilities I need (e.g. chmod) so it takes up less disk
space.

Hi,
My apology for leaving something rather important out, and that is you must
start in.ftpd with the -a option so that it reads the /etc/ftpaccess file.
For example, here's my /etc/inetd.conf file:
(... snip ...)
# Ftp and telnet are standard Internet services.
#
ftp stream tcp nowait root /usr/sbin/in.ftpd in.ftpd -l -a
telnet stream tcp nowait root /usr/sbin/in.telnetd in.telnetd
(... snip ...)
Hope this helps in some way.
Cheers,

ls looks to be good. The permissions are OK and ~ftp/bin/ls is the
same as ls on the system. Thanks for the suggestion though.

Did you check the copy of ls you created under the ~ftp/bin directory?
Perhaps the permissions on that aren't set properly or you have a bad copy
of ls -- or it isn't even there.

We had a similar experience here. A user was trying to
use Microsoft's ftp.exe in the windows directory. If she
used the "run ftp" and then used
"open somehostname.somedomainname"
at the ftp prompt, i.e. ">", she could get in but couldn't
list any files.
I had her change to using "run ftp someipnumber.x.y.z", and
she was able to get "dir" to work. This means it was either
a DNS related problem or an ftp client problem with handling
command line parameters, we didn't do any more detective
work since we found a working solution so I can't tell
you which it was. Hope this helps.

X-Mailer: Mail*Link PT/Internet 1.6.0
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Hello,
My name is Travis Greer and I am a senior CS major at Pomona College. For my
senior project, I am attempting to replace the tcp/ip socket calls (i.e.
socket(), bind(), listen(), accept(), read(), write()) with calls to FORE's
atm api. These calls establish connections over an ATM network instead of
traditional ethernet without the overhead of using ATM-over-IP.
I have been having difficuties understanding the flow of wu-ftpd upon startup
and as messages are received. I would like to know in which progression
functions such as dataconn() and passive() are called. I would also like to
know the significant data structs such as ctrl_addr and their purposes.
My current path to adding ATM connectivity is to just piggy-back atm calls at
the same points as the current tcp/ip socket calls (since they were designed
in a similar fashion). At this point I am hoping that they will be called at
the appropriate times and will work (somehow). A better understanding how how
wu-ftpd runs would be very helpful. Any assistance, suggestions, or comments
would be greatly appreciated.
Thank You,
Travis Greer

Alice,
If the user got to the right machine, it can't be A DNS problem , the name
resolution has been completed and an ftp session exists with a socket to the
TCP/IP stack.
This is somewhat simplified, but basically, the IP stack only ever
communicates with ip addresses (the machine name is communicated as data in
a name resolution request (the ip packet having a destination ip address of
the name server) to the Name server and the name server responds with data
containing the ip address of the target machine. DNS is done once and then
the binding is done, all subsequent ip packets have the ip address of the
target). ftp knows nothing about DNS, it just sees the socket which is
related to the target host session.
Of course if she did not get the right machine, that could be associated
with a DNS problem.
Regards Geofft

It's an int - 65536 (but it's unsigned, so it's 32768 connections a minute,
546 connections a second. You had better have a pretty hefty machine to
fork that often :)

Subject: ckconfig not same as pathnames.h

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

I just compiled wu beta 13 and when I do a ckconfig, I get this:
# ./bin/ckconfig
Checking _PATH_FTPUSERS :: /usr/local/lib/ftpd/ftpusers
ok.
Checking _PATH_FTPACCESS :: /usr/local/lib/ftpd/ftpaccess
ok.
which is great except that according to patnames.h, both of those files
should be in /usr/local/etc and the syslog errors that I am getting,
because I cannot log in, is:
Apr 9 22:02:40 josephus ftpd[17866]: cannot
open access file /usr/local/etc/ftpaccess: No such file or directory
So how did ckconfig get so confused? and I get another bizarre error. I
have anonymous ftp setup using the stock DU4.0 ftp, but when I try to log
in as anonymous under wu, I get this:
Apr 9 22:16:02 josephus ftpd[17888]: User anonymous unknown.
Apr 9 22:16:02 josephus ftpd[17888]: FTP LOGIN REFUSED (ftp not in
/etc/passwd) FROM josephus.furph.com [204.120.113.160], anonymous
yet in /etc/passwd and ~ftp/etc/passwd, I have this line:
ftp:*:9998:999:anonymous ftp:/usr/users/ftp:/bin/false
oh, and this is on digital unix 4.0, wu beta 13 compiled with build dec
thanks

Make sure you run the new copy of ckconfig. Go to your
/wu-ftpd.source.here/src/ and run ./ckconfig
You are probably running the ckconfig in your path and now the new one.

Look at the source.
grep on 'ock' in all the sources to hit the points you are looking at.
It's only about 12K lines in toto.
BTW the listen, and accept calls are tightly tied to the kernel tuning of
whatever OS you are writing to. Whatever you do, I would recommend testing
it against at least the following: Solaris2.5, Irix5.3, Irix6.2, Linux,
BSDI, and SCO. Otherwise, your efforts will only collect dust.
Also, the transliteration of the listen queue (default 5 on ALL unix unless
custom-tuned) to your API may also depend on whether you pre-allocate
processes or fork them. The caution you will need to employ is in making in
general enough to permit tuning to high rates of simultaneous hits. If you
ignore the tcp_sendspace and tcp_recvspace under IRIX,for example, along
with the tcp_keepidle values that the test box you are running on, you may
derive a faulty image of the way your code performs under duress.
In the case of Linux, the networking and the tools to derive info therefrom
are the most limited of the bunch.

Those four identifiers are defined in a replacement ftp.h header file.
On Linux, the original file is in '/usr/include/arpa/ftp.h'. On an AIX
system, it is possibly in the same place, definitely should be under
'/usr/include' somewhere. Copy the ftp.h file that comes with the
wu-ftpd source over it.

Dale,
Wish I could give you some info on using this Wizard but I couldnt even
get as far as you. How did you successfully get your ftp session established.
No matter how I entered the ftp address in the URL box and the rest of the
information prompted it still munged it up some and never connected
successfully to my server.
I was trying to do this without that server info file, did you end up using
that? If so would appreciate seeing how a ftp one looks since all their
examples showed http connectivity to ISP's.
Thanx,
Roger Hanke

If you are seeing Signal 11 in the syslog that usually means the
wuftpd daemon is dumping core or encountering something equally
severe like a segmentation violation etc. Its usually bad news. I
don't have a good way of finding out why its doing this.

Hi,
I am having a problem building the wu-ftpd environment. I solved
a complaint about vers.o being missing, but he following has me stumped.
I have found the identifiers defined in src/ftpcmd.y file, however I don't
see
where it is being called anywhere. I am a relative novice in coding at this
point
and any help would be appreciated.

On a HP-UX 10.01 machine using wu-ftpd-2.4.2-beta-11 we also had a
ftpd that dumped core and exited with signal 11. Your problem might
be something completely different, but in our I tracked it down to
a memory allocation problem in popen.c. I never came around to
investigate the problem in more detail but a quick'n'dirty patch
help me:
In popen.c in the function ftpd_popen (...) disable the release of
possibly unallocated memory near the end of the function body:
pfree:
for (argc = 1; argv[argc] != NULL; argc++)
{
#ifndef __hpux
#ifdef __comment__
GG: 1996-09-13, under HP-UX this seems to fail!!!
More details see: [%afs/etc/userdir/azi.hyx] wu-ftpd Bug 1
#endif /* __comment__ */
blkfree((char **) argv[argc]);
#endif /* __hpux */
free((char *) argv[argc]);
}
return (iop);
According to my notes (referenced in the source segment above)
this happened right after the client issued
a DIR. The memory leak cause by not freeing the argument list
seems to be neglible.

Hi!
As far as I know, 2.4.2BetaXX are just stop gap. No further code is being
accepted to it. Just shaking out the bugs.
All new code and features is going into 2.5.
Is there a list somewhere about features we would like to see or projects
for wuftpd? I have a coupple of them (passive mode port limit and radius
authentication) and I've being looking at the PAM stuff... Some parts of
Wuftpd are in need of a rewrite (and I would not mind do it in some
places), to clear up a lot of ifdefs...
Also, the ftp-wg is putting out some drafts on new commands for the
"ftp-ng". It migth be interesting to look into it and to have some
knowledge so that later wuftpd could migrate to it without much rewrite.
hmms... Well, for me, I use wuftp a lot, and I would like to see it grow.
It's free, so it must be suported by the people who use it...
Comments are welcome.

Subject: Timeout-Patch for WU-FTPD 2.4

Content-Transfer-Encoding: 8bit
X-Mailer: ELM [version 2.4 PL25]

Hello,
We are using wu-ftpd 2.4.
Some of our customers are using our ftp-server for massive file exchange
between Russia and Germany. Due to the rather bad telephone qualitity
in Russia, transmissions of files often abort with a hangup of the
local modem. Because of this, the running wu-ftpd process will never terminate
(timeout feature is only working when in idle state).
We ran into difficulties when a lot of aborted transmissions with remaining
server processes filled up the user classes.
I implemented a patch for wu-ftpd-2.4 which applies to ftpd.c.
It makes use of the "select"-function during file transmission and
receiving and applies the same timeout as defined for idle timeout
as the maximum interval between two data packets.
This works in ASCII as well as BINARY-mode. I roughly tested the patch,
but as I reimplemented the ASCII-conversion, I cannot absolutely
guarantee the identical behaviour for every kind of file.
I don't know if 2.4 beta contains a similar feature. If it does, please
excuse.
I'd consider the current behaviour of wu-ftpd as a (minor) security
whole, as an attacker might lock up a whole class of users by starting
up as many ftp-processes the server allows him to do, abort them during
transmission of a file, and leave the ftp-server unusable till the
operator kills the processes or reboots the machine.
You will find the patch at:
ftp://ftp.pop.de/pub/LOCAL/wu-ftpd/wu-ftpd-2.4-timeout-patch
(This is also an opportunity of checking out the patch :-) )
Hope it helps,

to be precise in the main control loop

Yes there was a long thread on this issue, 1 or 2 months
back. Subject was "hanging ftpd", you can check out the archive
for more.

One of the cons of this approach was pointed out by Bob ...(?)
His server was uploading file over 24 hours.
So what's a good timeout for the data transmission ?
*
Another way is to move out the timeout and make it global
So any process will harakiri after 24 hours ... a bit rude :-)
*
send a probe
*
I don't remember all the ideas, but I use the KEEP_ALIVE
approach on the data socket. So there was no need to play
with select() nor alarm()

why not ? I didn't follow the argumentation here
1- Dowloading we don't worry
the write() will return -1, errno set end of story.
2- uploading
If you use alarm() you can put it before the read loop.
If you use select() enclose the read()'s inside a select() loop.
why is the file type important to your mechanism ?

no it doesn't and wu-ftpd is up to beta-13,
Wu-ftpd is maintain by Stan Barber. Maybe you can send your
ideas to him, for release 2.5

yes it is a pain, but that is not entirely wu-ftpd's fault
That's the way TCP/IP works, It's hard to know when
a peer goes AWOL.

I suggested that thif this does get implemented, it should be controlled
by a switch in the ftpaccess file. Then if you find you need to change it
to fine tune your setup, you won't have to recompile. You should also
be able to turn it off by setting the switch in the ftpaccess file to say, 0.
It's clear that what is a good timeout value for one site is not going to
be good for another, so it needs to be easily configurable...

One of the cons of this approach was pointed out by Bob ...(?)
His server was uploading file over 24 hours.
So what's a good timeout for the data transmission ?
Another way is to move out the timeout and make it global
So any process will harakiri after 24 hours ... a bit rude :-)
So don't make it global but make it an attribute of user classes. That
would allow for long file transfers if the user is in an appropriate
class and give decent timeouts for processes in other classes.

Though the idea to make the "transmission timeout" configurable is correct,
I'd like to point out two things that might be missunderstandings:
- The Timeout-Value for transmission is the same as the one the the
main loop, so the user can adjust it by the "SITE IDLE" command
and the sysop can control the default value.
- The Timeout-Value is for a single *block* of data, not for the whole
transmission. This means, the used buffer size (1024 in my case),
depending on the value defined in stdio.h is the number of bytes
that have to be received before the timeout applies.
Therefore, even 100 MB files would not cross the limit as long the
connection does not hang for the specified time.
I'll think of implementing an independent configurable value.

Georg

I realise that this works fine for you. :-) But if we are talking about an
implementation for general use in release 2.5, it might be better if they
didn't both key off the same value. For example, some sysops might want the
"hang" timeout (for want of a better name) not to be changeable by the
user... (As opposed to the idle timeout.)

Ah, yes. In the discussion a few weeks ago when I made my comments, we were
talking about a timeout value for the whole file transmission, not a single
block. Doing it on a per-block basis makes more sense for the purpose
we are talking about. Thanks for clarifying this.
(BTW, _some_ of our files are nearer 500 MB (after gzipping) than 100 MB,
so you can see why they take a bit of time to get there...)
> I'll think of implementing an independent configurable value.
:-) Thanks for this, too. !

This is being monitored. Anything that is draft standard or higher will be

via the anonymous (or any other account for that matter) ftp login. I get

The ftp log file doesn't really tell me anything interesting, but the welcome

Any ideas on what the fix might be are appreciated.

Is the server starting with the -a cmd line option (which causes it to use
the /etc/ftpaccess file)?
If so, whats in your ftpaccess file and whats in your ftphosts file.

This _usually_ happens because your ftpaccess file has a "shutdown" line
specifying a pathname in it. If this file exists, the server reads it to
see what date/time it contains, and if the current date/time is beyond that
the server rejects connections.
Check to see if this file exists, and if so delete it or change the date.
You might have created this manually, or by running ftpshut. Either way,
once the specified date is past, you have to remove the file or set it to
the next planned shutdown time before the server will allow connections
again.
For more information, check the ftpaccess and ftpshut man pages included
with the distribution...
Good luck !
Cheers, Bob

People,
I copied the wu-ftpd from wwachive but had to make 2 changes to get it
to compile? has anyone else had these problems.
I am using a sparc5 running solaris 2.5 (without patches) and a SUN
SPARCcompiler C 4.0.
I commented out the function "strstr" in the file support/strcasestr.c
because it is a reserved world? and indeed I assumed already
implemented in ANSI C?
More seriously I needed to change the yacc line in src/ftpcmd.y on line
577 which yacc refused to compile? it was...
reply(215, "UNIX Type: L%d Version: BSD-%d", NBBY, BSD);
and I changed it to?
reply(215, "UNIX Type: L%d Version: BSD-%d", NBBY);
Has anyone else had these problems? what are the implications??
Thanks for any advice anyone can give me...

Subject: which S/KEY code to use?
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
I am trying to get S/KEY & wuftp 2-4-2 beta 12/13 to work
together.
I am using the skey code that comes with logdaemon5.3.
Does anyone know of a better version to use?
Right now, the ftp daemon I have compiled works, but
it is flakey. It currently works only when skey passwords
are used. It doesn't matter what 'permit' lines I use in
/etc/skey.access, nor if there is an /etc/skey.access file,
ftp doesn't allow unix passwords.
There is strong evidence that this is not a configuration problem.
The message log shows that the ftp daemon catchs signal 11,
segment violation, when any attempt to use unix passwords is made.
My first guess is that I have a source code version mismatch
between wuftp and s/key, but haven't found anything that could
confirm or deny this.
Are there any configuration or compilation settings I might
have missed that need to be set to allow use of the /etc/skey.access
file and/or to allow using both unix and s/key passwords?

Subject: Hiding new uploads
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
How can I set up anonymous ftp so users can upload to an incoming
directory, but will not be able to see any files in that directory while still
being able to see files in other directories? Is it possible?
e.g.
/incoming -> allows uploads, files not viewable
/pub -> no uploads allowed, but files viewable
I've got the upload permissions set okay, I just can't seem to hide files.
Thanks.

These snippets of code are in ~/src/ftpd.c; the pwok=1 must be there to
enable regular passwords. Comment out the wrongo:spazmoid line also.
Recompile, reinstall, and try again. See if that doesn't enable
passwords.

These directions are on the FAQ site at:
http://www.cetis.hvu.nl/~koos/wu-ftpd-faq.html
7.Somebody uploaded a file with a weird name
Somebody is trying to misuse your ftp-site for transferring software (worst case scenario). Check if the directive
path-filter in the ftpaccess file is something like :
path-filter anonymous /etc/paths.msg ^[-A-Za-z0-9\._]*$ ^\. ^-
8.I want anonymous users to be able to upload files, but in the most secure manner possible
In that case, set your path-filter to the one mentioned above. Make the incoming directory owned by something
else then ftp (root, or nobody) with another group then ftp (nobody). Something like :
drwx-wx-wt root nobody incoming
This will allow ftp to write in the directory, but not read it. Set the upload directive in ftpaccess to something like :
upload /home/ftp /incoming yes root daemon 0400 nodirs
One note : files get created as root and changed to the owner mentioned in the upload line. This will fail on some
secure NFS setups.

I do not formally test skey support in the beta, so it could be broken.
If someone will do that testing for me before I release beta-14, I will be able
to consider the fixes. Otherwise, it will not be fixed in beta-14.

Is there an way to limit multiple anonymous connections from a single
host? Perhaps a patch of some sort?
Thanks

Subject: Thank you! Re: Hiding new uploads
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
I seem to have gotten things sorted out here. It seems that I originally had tried to
use '/pub/incoming' but put '/incoming' in the ftpaccess file. I had also originally listed
the <root-dir> for 'upload' as '/u02/export/home/ftp' while the '/etc/passwd' file listed
the ftp home directory as '/export/home/ftp' (a symbolic link, for historical reasons),
which did not work (I can't find *THAT* in the FAQ, although if I took the time to read
the source code more thoroughly I might have noticed it).
By the time I noticed the first error, and had removed '/pub/incoming' and created
'/incoming' I completely forgot about *directory* permissions. By the time I posted
a message, I had spent a good half hour fooling around with the <mode> parameter
for 'upload' with no results.
And yes, I have read the FAQ. (I've even bookmarked and printed it since the only time
I've actually seen the address posted is when somebody is complaining that you haven't
read it.) Interestingly, the Solaris (my system) How-To specifically talks about setting the
permissions on the '/incoming' directory to 777 while the regular FAQ does not mention
setting permissions explicitly (although this excellent document, without which I never
would have got the package running, does list the permissions, but does not call attention
to them).
Anyway, thank you all for your help.

Subject: Re: which S/KEY code to use?
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Thanks to all.
I am now using logdaemon.5.6. and wuftp beta 12.
The version of skey was not the problem, nor did I want
to force pwok=1.
ftpd.c needs a call to skeyaccess() to turn on the
use of the /etc/skey.access file. This allows unix passwords,
but not in the wide open manner of the previous suggestions.
I want to use this file to allow unix passwords from certain
logins, and from certain IP addresses only.
It would be nice if the wuftp/skey combination would also check against
the IP address bound to the local end of the socket, to
further reduce IP spoofing possibilities. But its already
been a long day.
-------------
The fix to ftpd.c is:
1204a1205
> pwok = skeyaccess( pw, (char *)0, remotehost, remoteaddr);
Starting at line 1203 of ftpd.c, the code looks like:
#ifdef SKEY
/* 0 means we found the user and the skeykeys file is open for update. */
pwok = skeyaccess( pw, (char *)0, remotehost, remoteaddr); /* NEWLINE */
if (skeychallenge (&skey_blk, name, chbuff) == 0)
reply (331, "[%s] required for %s.", chbuff, name);
else
#endif
pwok is set to 1 only if the parameters given to skeyaccess fit within
the rules in /etc/skey.access.

My apologies.
Beta 13 has the fix.
It's been a BAAAAD day.
Beta 13 and skey from logdaemon.5.6 work just fine.
I have no idea what screwy thing I did to get
so confused.

If anonymous works ok, if real users work ok (as predestined by the format
of your ftpaccess...correct path BTW? You have run ./ckconfig YES? to check
for these things?), then your setup has a busted 'ls'. On Solaris you can
run 'truss', on irix the following (since they are stored literals) works:
strings -a bin/ls | grep \\.so
for the dynamically shared objects (for which, the right outcome is NIL).
On Linux, I don't know. But let's not ignore the obvious:
Is your ftpusers correct and only listing the ones who CANNOT ftp?
Your Redhat ships with GNU c if I remember correctly. Read Jeff Hanson's
comments on building a non-shared 'ls'. The CFLAGS and LDFLAGS setup is
crucial. Get the fileutils-3.16 and go to.
The most recent communiques won't be there, but I hope you know:

Subject: Ftp to the site with <user>&<passwd>
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Hi !
I was trying to adjust my ftp server to accept sub-logins so other users rather
than ftp & anonymous could login with user&passwd to our server.
The server runs on Solaris 2.5 and I modified it according to what I've read in SunSolve
so the above will operate.
My problem is that each time I try to use the 'user' command (after logging to the ftp account)
and enter the sub-login area I get the following message :
530 Can't change user from guest login.
Login failed.
This happens though I'm using Solaris 2.5 which suppose to support this feature.
Do you have any suggestions ? and if not, could you address me to someone who can ?
Thanks in Advance,
Tomer
Ps. How can I modify the site so users can login as <user> directly ?

Wu-ftpd doesn't do sub-login period.
It was flushed out because of security concerns
since version ??? (long time ago)
If you want it, you have to go through the src code
and comment out the relevent `if else'

Dunno about the solaris generic ftpd, maybe they still have this

Hello
This was sent to a BOS mailing list, I thought it was appropriate
to x-post.
There is a small glitch in the way ftpd(popen.c) handles the
arguments. I've sent mail to Mr Barber in Jan about this, but
my patch was not retain, it was probaly to drastic(I refused
to exec if argc was too long :-). The patch can still be found
if you browse the archive, I guess. But it may be best
if you wait for beta-14.
The fix in beta-13 still have a problem, I believe
it's probably because the array, argv[], is not NULL terminated
if args goes over MAXG_ARGS.
See src/popen.c for the relevant code.
Wu-ftpd should not dump core or do anything else then dropping
the connection. Must signals are catch(randomsig()). I don't think
this buffer overrun can be exploitable because the function
never return (execv()); I'll send something to Stan(Mr Barber)
if he didn't already correct this.
Here is a trace of the loggin sesion:
read(0, "user ftp\n", 4096) = 9
...

Is it possible to allow only certain IP's to access a particular
account? If not, is there any way to block all access except from several
(say 3) IP's at all? I know how to deny service to IP's but if I only want
to allow 3 in, isn't there a better way than trying to name all IP's in
deny? TIA

Does anyone know where I can find a list of the utilities I should add to
/bin for a "safe" guest account install. I want my users to access their
directories to upload / download web pages but nothing more. Or at least
nothing that will put the system at risk.

i am new to the list, so forgive me if this question has been asked
before.
is there a way to chroot real users to their $HOME upon their ftp'ing
in (like you do with anonymous ftp'ing)?
i have searched around, and have not been able to find the answer.
someone suggested that we use ncftpd, which does allow this. never
knew they had a daemon, though, and want to stick with what i have
familiarity with.
thanks.

Greetings:
Stupid question. I'm trying to upgrade from wu-ftpd2.4(1) to
version 2.4.2 beta 12. Build and install go great but when I try to
use my old ftpaccess file (with -a option) nobody anonymous or real
can get in. Seeing as I only modified a tiny bit from the examples
I'm stumped.
I'm not a regular on this list yet so any help would be appreciated and
should be sent directly to me. Thanks much.

I'm running wu-ftpd 2.4 on an A/UX system. My problem is with
anonymous ftp. Depending on the ftp s/w used to connect to the
archive I am having problem. If using for example 'ftp' provided
as part of the Winqvt package, when the user connects, he can
list files and directories with 'ls'. However, if the user is
using WS-FTP, the ls command returns an empty list even when
files exist in the directory. It is possible to cd down through
the anonymous ftp hierarchy but never to see what is there. Can
anyone help me on this on.

We just got it running yesterday on an Alpha with Unix 4.0B (upgrade to
B).
The problem is that the /bin/ls is not statically linked. Copy (or hard
link) /sbin/ls to the relative /bin directory for anonymous and guest
users and life should be good. As for real users, it all depends on the
path variable I would imagine. Make sure /sbin is listed before /bin in
the user's environment.

It may be the difference between using the ls and dir commands. Try
signing into your server with the client that works and do both an ls
and a dir. I bet your ls works but dir does not. If so, this is
probably because the ls you have in the /bin directory does not work
properly (I think ls is part of the ftp server and dir is an "outside"
command). One client is probably getting the directory list with ls and
the other with dir. We found the the copy of ls in the real /bin did
not work, but the statically linked one in /sbin/ls did work. Once we
copied the /sbin/ls to the relative /bin for the anon and guest users
all was well.

We are very satisfied with "xinetd" (which is similar to tcpwrapper).
But it doesn't control access to a particular account, the access rights
are set for particular services (telnet, ftp, ...), and it does a rather
comprehensive logging (access granted / access denied).
Its config file provides such access filtering by entries like:
service ftp
only_from ..........
or: never_from ..........
( "........." ist a list of IP addresses.)
Hope this helps.

--------------C3D0B887E1E28C8CEA8934F1
Content-Type: text/plain; charset=us-ascii

I'm having trouble getting directory listing's to work when connecting
to wu-ftpd-24.-beta13 running on Solaris 2.5.1 when connecting
with WS-FTPD LE from windows 95.
On the Sun box I get the error in /var/adm/messages:-
Apr 15 11:38:47 sun5 ftpd[29020]: refused PORT 0,1076 from
netfm.demon.co.uk
In the WS-FTPD LE 95 client program I see the error:-
PORT 181,100,100,98,4,52
500 Illegal PORT Command
DoDirList returned 0
This problem occurs for all ftp accounts on the machine, with or without
making them secure with "guessgroup all ftpgroup" in ftpaccess. It
even occurs if I turn off the ftpaccess file by using the -A option.
If you connect directly using DOS ftp, both the dir and ls commands
work fine. How does ws-ftpd do a directory listing ? Can I get the
WU-FTPD to log these methods to try and debug this.
Thanks in advance,
rgds dave.

We are looking to set something up to forward data which was FTP'ed to a
centralized FTP server (running wu-ftpd of course), and have the
origional file deleted from the centralized FTP server. I've looked into
an SNMP trap which requires an SNMP manager application.I can but would
rather not modify the ftpd source from WU.
Does anyone have any suggestions whereby a script/program can be
automatically invoked upon a successful FTP request to forward the data
to it's final destination server?
Thanks.

We do a similar thing here, but we use "mirror". We don't delete the
files, just copy them again (via ftp) when they change...
If you want more custom behavior, you could set up logging of transfers
(just a simple change to ftpaccess file). If you don't mind a
little delay, you could run a program from cron every couple of minutes.
Just a fairly simple perl script would do it. Or have a daemon tailing the
xferlog.

I've since discovered that putting the WS-FTP LE 95 into PASV mode
solves the problem. Also noted that a "dir" command or an "ls" command
issued directly from a DOS ftp session failed first time, then succeeds
on
all subsequent attempts.
There is definitely sometime wrong here, as a standard Solaris FTPD
does not required the client software to use PASV mode. TCP_WRAPPERS
are being used, but when disabled (removed from /etc/inetd.conf) the
problems remain the same.
Any ideas on why PASV mode succeeds ? Is it better for clients to use
this
client initiation mode - more secure ?

One way is to let the log entry trigger the forwarding, by letting
swatch or some similar daemon monitor the logfile, and start the
appropriate script when the log entry matches some log entry pattern.
swatch is (hopefully still) available at
ftp://sierra.stanford.edu/
pub/sources/swatch.tar.Z. It's Perl-based.

Hi
I have setup wu-ftpd successfully. All the users are limited to there
directories, with chroot etc.
BUT, how do I setup anonymous user, so that they can get access by just
typing in there email address for the password for example. I am not
sure if you set this up as you do for a normal user, or do you need
something different. I have had a look at the FAQ and I can't seem to
find what i am looking for
Thanks

You need to create an account on your system by the name ftp and set it
up the same as you do for the guest accounts. The username ftp will
have special meaning to the ftp daemon and will allow the user to log in
as either ftp or anonymous by providing any string as a password (though
you can enforce using an email address, etc.).
Read the ftpd man page that came in the distribution of wuftpd for more
information (search for ~ftp) on setting up an anonymous account. Read
the man page for ftpaccess that also came in the distribution for more
information on setting password checking rules for the anonymous
account.

I have the Daemon running OK, but it just times out when I try to
connect to the virtual host (even from a local terminal).
Any help would be greatly appreciated.

Ftpd servers, solaris nor wu-ftpd, force clients to
use one or the other(POR|PASV).
To download files you can do it via PORT or PASV
some 'OS' i.e DOS, Windows, etc
don't handle the PORT directive very well, then it's
up to you to specify which one you prefer.
Most ftp client on Unix will use by default PORT
Most web clients will use by default PASV.
>
> Any ideas on why PASV mode succeeds ?
if you try with other ftp clients (ncftp, ftp , netscape, ee, etc ..)
and it works than this client or the tcp/ip stack is broken
If not then your setup is wrong
check the faq or the man pages to see what
you must have in
lib/*
dev/*
etc/*
Solaris needs a handfull of libraries and missing one
can cause havoc or ftpd to behave strangely
- ls -l will show nothing
- or the wonderfull
"cannot create data socket (0.0.0.0)"
> Is it better for clients to use this
> client initiation mode
the server doesn't really care.
If you're behind a firewall, it may be a problem.
You'll have to open the ports somehow I suppose.
There is a patch from Pedro (?) in the archives to limit
the range of ports.
> - more secure ?
?
PASV and PORT are eqivalent in term of 'security'
Which really doesn't do much
The beta-xx doesn't accept on PORT, ports lower then 1024
and it must be the same IP

this is from the *ftp client*, I'll bet with you
you're using /usr/ucb/ftp :-)
It means that server went away (KabOOM !!)
the client lost the connection.
Now Why ?
dunno,
checked the logs ?
is this repeatable ?
do you have an entry in the log saying
" exit on signal xx " ?
bring up the level of debuggin on the server
and trace
send the relevant logs, maybe someone can come
up with some answers if you din't find any

How do I change the limit on ports <1024, and do I really want to
to do this. I.E why is the beta-xx set like this ?
I'm using FTP 2.4.2 beta-13, is this the latest ? e.g:-
220 sun5 FTP server (Version wu-2.4.2-academ[BETA-13](1) Fri Apr 11
09:52:06 BST 1997) ready.
Thanks for the excellent responce,

I have set up several guest accounts on Solaris and in all of them
have a /etc/passwd file either containing the pertinent users or the full
passwd table. However in a directory listing, it only shows the UID's and
GID's. I saw this question posed before on the list but never saw the fix.
Any ideas? TIA

David,
My understanding is that if there is no /etc/group or /etc/passwd file
locally for the users (relative to their chrooted environment), then
they cannot resolve the UID and GID in dir listing. If you create a
/etc directory for each chrooted environment and copy these files into
that dir, they will show up. However, there is a security concern of
have a list of all your user accounts available to the public, so you
may experiment with removing the password from those files and also
removing extraneous accounts that will not have files below the chrooted
environment anyway. Also, consider if it is worth it at all to have
those files present. Do people really NEED to see a username as opposed
to a UID?
Cheers,
Rich

This was my understanding as well. However I do have an
/etc/passwd & /etc/group in the chrooted dir. It still doesn't work. I
have expermented with partial and full passwd lists to no avail. With
Solaris there is not much of a security concern since it uses shadowed
password tables though.

This is something I don't agree with because
it is in clear violation of the Protocol as define by
the RFC. But I can understand the reasons.
Also if you're patient there was a long thread on this a year
ago, so it's in the archive.
Let me resume the thread for you with some examples
of the danger of having ports < 1024.
DATA PORT (PORT)
The argument is a HOST-PORT specification for the data port
to be used in data connection. There are defaults for both
the user and server data ports, and under normal
circumstances this command and its reply are not needed. If
this command is used, the argument is the concatenation of a
32-bit internet host address and a 16-bit TCP port address.
This address information is broken into 8-bit fields and the
value of each field is transmitted as a decimal number (in
character string representation). The fields are separated
by commas. A port command would be:
PORT h1,h2,h3,h4,p1,p2
where h1 is the high order 8 bits of the internet host
address.
When data is to be transfer between a client and a server. The client
can specify to which port it wants the data to arrive. The client then
listen to the port number specify in the PORT command. The server makes an
active open to that port and sends the data.
Like we discuss before the host specify in the argument portion of the PORT
doesn't have to be the same IP as the client, hence open the door to
all sort of abuse. The easiest example that comes to mind is fake email.
.....
STOR smtp_file
PORT a,b,c,d,0,25 # a,b,c,d --> a.b.c.d --> victim_ip
RETR smtp_file
This sends an untracable mail to victim_ip. The logs on victim_ip will
always show that the connection was made by the FTP server. It's a good
way to pass thru firewalls.

We discovered this last week, as we upgrade our ftp server to
2.5.1. We fixed this by copying the right libraries to ~ftp/usr/lib,
ie as explain in the ftpd Solaris manpage :
ld.so*
libc.so*
libdl.so*
libintl.so*
libw.so*
libnsl.so*
libsocket.so*
nss_nis.so*
nss_nisplus.so*
nss_dns.so*
nss_files.so*
straddr.so*
You may need other libraries. I remember that our version of gtar
requires /usr/lib/libmp.so.

Could someone please tell me how I can set up the message/banner files
when login and out of WU-FTPD 2.4. I'm currently setting up WU-FTPD 2.4
on Solaris 2.5.1.
Are "message" and "banner" commands?
Thanks very much.

Why does ftp'ing directly from a web browser not take a user directly
to their home directory ? If the user is setup as a guestgroup user,
then
the chroot part works correctly - but the follow on part "/./homedir" is
not cd'ed into. If it's a normal "real" user, then you end up in the
root
diectory.
I.E
ftp://username:password@IPADDRESS/ aways puts you in "/", not
the username's home directory.
Any ideas ?
I suspect it's the default browser behaviour - I see this on Netscape
and IE,
obviously you can put
ftp://username:password@IPADDRESS/homedir to get
you to your homedir.

That's the way the ftp URL scheme works. Any browser that handles ftp
URLs differently would be working incorrectly. Otherwise there would be
no way to refer to the root directory in a URL, which is clearly
incorrect behavior.
Also, I recommend not using the password in the URL. All browsers I
know of will prompt you for the password if you don't give it in the
URL, and I think that's a better way of handling passwords.
I.e., just use
ftp://username@IPADDRESS/... instead.

I reported this on arpil 10, and I'm still having this problem. This is
beta 13, Digital Unix 4.0, started up in inetd.conf like this:
ftp stream tcp nowait root /usr/local/etc/tcpd
/usr/local/bin/ftpd -l -d -a
and I get this error when I log in as anonymous:

even though I'm using the right password.
/etc/passwd and ~ftp/etc/passwd are this:
ftp:*:9997:999:anonymous ftp:/usr/users/ftp:/bin/false
ftp1:*:9998:999:guest ftp:/usr/users/ftp/./:/bin/false
/bin/false is in /etc/shells
ckconfig checks out that ftpaccess is in /usr/local/etc/ftpaccess and in
it is the following:
class local real,guest,anonymous *
guestgroup ftp1
And it seems like the daemon is just ignoring the -a in the startup. Any
ideas, PLEASE!
thanks

OK 3 things.
1. I dont thing authentication uses the ~ftp/etc/passwd file (its there so
chrooted anonymous sessions get names in lieu of numbers in directory listings).
2. Whats in the ftp hosts file ??????????? /etc/ftphosts (is the default
with the distribution I think) It may conflict with your IP address. Does
the DNS know about the client machine.
You could also try ftp 127.0.0.1 from the server and see if that gets the
same problems.
3. Does root have read access to the ftpaccess file (its a dumb question
but........)

Subject: Notes on general oddness...
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Hi!
Here's some notes jotted down during a recent read-through of the beta-13.
As I don't feel very comfortable with wu-ftp, and don't think I understand
why it does what it does, I hesitate to suggest that these are actual
problems. They look a bit odd, though, and so may be potential problems.
ftpd.c, retrieve():
The call to dataconn() defines dout and data. fclose(dout) closes dout,
immediately after send_data(), but data isn't reset until just before
the end of the function. It isn't clear why they are separated this way:
it rather tends to make the connection betwen them non-obvious.
ftpd.c, store():
The closefunc pointer doesn't appear to be useful, as only one assignment
to it ever takes place.
If fchown() for some reason goes wrong, fdout is not closed. This
is probably not a problem, unless fchown *always* goes wrong -- this would
leave a lot of file descriptors open. (Actually, this is the only
thing I feel fairly sure could be a problem, although only under pretty
weird conditions.)
Same 'problem' with dataconn and din as in retrieve().
ftpd.c, dataconn():
Uses 'data' to decide if an existing connection could be used or not.
But data seems to be reset to -1 in all cases, so this code appears to
be non-functional.
'pdata' seems to be used in a somewhat similar way, but also seems to get
reset to -1 everywhere. See below, though.
extensions.c, newer():
This seems to be the only place where dataconn() is called, and the file
later fclosed() and data is reset to -1, but pdata *isn't* reset. Deliberate?

I tried it on mine and it puts me in the home directory of /dsk1/home/skb with Netscape 3.01

Hi List!
I configured my real users to access only your directories in my
server exactly how work anonymous users. I configured my /export/home
directory with bin, etc, usr and lib directories and homes of my
users to /export/home/./user. All work fine, but when I access the
URL www.ez-poa.com.br/~user the content of directory isn't showed in
browser. In ftp tools or shells, this files are showed.
Anybody have one idea about how solve this problem?
Thanks in advance!

Are you sure you've created the ftp entry in /etc/shadow as well as
/etc/passwd, and are you sure you've compiled wu-ftpd with shadow password
support?

It doesn't have anything to do with ftp - the browsers use the HTTP
protocol (on port 80) to access URLs unless the URL starts in ftp://,
gopher://, etc.
With most browsers, your users can see the contents of their home
directories on
ftp://user@ez-poa.com.br/ (if they know their passwords).
If you want people to be able to access user home directories over the
WWW, it's a matter of configuring your WWW server.
If you are, by any chance, using the apache www server
(
http://www.apache.org/), it can be accomplished by setting "UserDir" to
"." in srm.conf

Digital Unix 4.0 does not use /etc/shadow for its shadowed password
files. With C2 security installed on the system, the /etc/passwd file
is "shadowed" but the encrypted passwords are stored in a series of
files elsewhere on the system.
You can read the DU 4.0 security manuals for more info.
BTW, wouldn't publishing part or all of the /etc/shadow file for
anonymous FTP users kinda ruin the effect of having an /etc/shadow in
the first place?

Your passwd file does not include passwords; they're stored somewhere
else. On most systems, that's /etc/shadow; maybe it's somewhere else for
you.
Try "man adduser" or "man passwd".

Richard,
I agree, but I dont think that is suggested.
I dont know Digital Unix and I dont currently run beta13, but unless its
changed since beta11, you dont need to put the passwords (shadowed or not)
in the public ftp directories.
The chroot is done after login authentication (otherwise it knows not where
to chroot to!)
The only reason you put the /etc/passwd file in the ftp tree is for the ftp
daemon to provide names in lieu of unix uids & gids when the client does 'ls'

the question is - why can neither real or anonymous users log into wu-ftp
beta 13, compiled under DU4.0, without c2 security? The answer is, if you
use the dec, as opposed to osf, makefile, you pull in a config file that
defines something called SECUREOSF, which then uses bigcrypt to encrypt
the passwd, which you don't want, unless you're running C2. undef this
variable in the config.h and you're golden.
I'm sending this to wu bugs only because it is not documented in the
install file.
thanks

I just compiled beta 13 and ... I have no problems at all.
How does your src/config.h look like ?
make sure SECUREOSF is NOT defined. you just need it
for C2 security level.
"build dec" compiles fine with SECUREOSF when
the OSFC2SEC4xx subset is installed, but then
ftpd fails because C2 is not configured.
Hope this helps.

Miguel

Hi everybody,
I noticed very old STOR commands with 'ftpwho' like (today) :
24814 ?? IW 0:00.35 pppK13002.micronet.fr: bigboss: STOR Index.html\r\n (
bigboss 24814 0.0 0.0 452 20 ?? IW 4Mar97 0:00.35
pppK13002.micro
^^^^^^
For the moment, I need to manually kill them.
Is there is any patch for wu-ftpd-2.4.2-beta-12 to solve this problem or will
I need to make a cron to automatically kill them ?
BTW, could you explain me why this version of wu-ftpd on a HP-UX 10.10 system
gives a non-easy readable output :
1 S 0 17180 1269 0 154 20 3a4c400 45 390ef68 ? 0:00 ftpd
Is there any configuration to do that ? Thanks in advance for your help.
Gildas.

Hi,
simple question:
Can I (with the virtual server option compiled in) have multiple
anonymous logins? I want to have one anonymous area connected

Hi,
I'm running 2.4.2 beta 13 on Slackware 3.1.0, kernel 2.0.29.
Everything works great, save for the fact that although the file
/var/log/ftpd/xferlog exists (I had to create it using 'touch'), and the
config files pointed to it, the ftp server won't log anything. xferlog is
owned by root, and has the protections -rw-r-----. Did I miss something
obvious?
Thanks in advance -
Josh Mayers

Hello all,
Is there a compile option to remove the SITE EXEC feature in the
non-beta version of 2.4? I could not find any documentation on compile
options in the instructions - only to modify the pathnames.h. I have
seen several people on this list talk about compile options. Is there a
doc I am missing on this? If there is not a compile option, is there an
option in the ftpaccess? I could not find anything about this and was
leary of hacking the ftpd.c source to remove the site exec.
Thanks,

/Stefan,
# simple question:

Yes you can. There is a document (Supporting Virtual FTP Servers in WU-FTPD)
that explains more about setting it up at

Not sure, but could be that you should use the -a flag in inetd.conf...

I know chroot ~ftp is picking up the passwd and group files because

Does anyone have any ideas what might be wrong ?
Thanx in advance.

I seem to be missing something - there is no file named
FIXES-2.4-HOBBIT, only a FIXES-2.4. Also, there is no PARANOID defined
or undefined in my config.h file. Where did you come across this info?
Do I have a different version? And though there is nothing in my exec
dir, I AM paranoid and may want to define myself as such ;-)
I have been to the wuarchives and I seem to have the latest
distribution.

the chroot in this case is
chroot("/local/disk1/ftp")
chdir() reports that there is no dir. in
/local/disk1/ftp call /local/disk1/ftp/./
i.e:
ther is no
/local/disk1/ftp/local/disk1/ftp/./
in other words create this
mkdir /local/disk1/ftp/local/disk1/ftp
and
cd ~
will work fine
dunno if I was clear enough, english words do not come easy
for a french person, to many if's then :-)

He was asking about NON-beta releases.
I don't believe the stock distribution has an easy way to disable SITE
EXEC. You'll either need to muck around in the source code, or migrate to
a 2.4-beta release, available from ftp.academ.com:/pub/wuftpd/private.

The first step is to not delete the confirmation message that you get when
you subscribe to the list. But since it appears you've already deleted
that informative message (which, by the way, tells you how to
unsubscribe), I'll tell you:
Send the message "unsubscribe wu-ftpd" to
[email protected]. Note
that I said "message", not "subject" (subject field should be empty).

agreed, after the fclose(dout) the file descriptor(data/pdata) is close.
I'd say, it's a question of style ?

not so weird /home/ftp may have been mounted rd_only
or the uid.gid are wrong etc ...
I guess the philosophy behind BSD-ftpd was it's a short
live process spawn by inetd, so no need to be clean.
ftpd is leaking memory all over the place, also.

This code went to so many patches/enhancement,
They say, when you don't know, it's better to live it alone (i've
learn this the hard way :-)
Somewhere in the rfc, it says that the client can use the previous
data port if no PORT/PASV command is issued, of course
nobody uses that because of TIME_WAIT and EOF will close the con.
This was discourage later in an other rfc 112x something.

It's one of those questionnable extensions :-)
I suppose the author didn't foresee that Web browser would
have make the PASV mode so popular :-)
I agree with you, if the client always uses PASV mode
for the data transfer then pdata should have been reset to -1.
It may be a problem but it's very hard to know, must
clients are very well behave and reissue a PASV or PORT
before any data exchange.

Hi all,
I am having a problem with getting my virtual ftp to work. I have =
BSDI2.1 and wu-ftpd.2.4.2-beta 13. I have compiled it using the =
-DVIRTUAL FLAGE in the Makefile.
I have set up a test domain devil-dog.com
I have set up ip aliase for 207.53.207.253=20
I have tested out pinging ftp.devil-dog.com and it returns the ping.
I have made entries in the ftpaccess file
virtual server at 207.53.107.253
virual 207.53.107.253 root /var/ftp/virtual/devil-dog
virtual 207.53.107.253 banner /var/ftp/virtual/devil-dog/msgs/banner.ms
virtual 207.53.107.253 logfile /var/ftp/virtual/devil-dog/xferlog
When I attempt to ftp to ftp.devil-dog.com it takes me to my anonymous =
ftp server. Is there something that I forgot?
any help would be appreciated.
thanks
Joe

I need to setup wu-ftpd to use an alternate method for auth. How can I
make wu-ftpd use lets say for example /etc/ftp-passwd ??

Hi,
Thank you all for the responses. Apparently I was unsubscribed in some
odd manner in which I wasn't notified. I've simply resubscribed, and
everything's back to normal now.
Thanks again!

Hi there,
I managed to get the wu-ftpd-2.4.2-beta-12 version to compile
on AIX 4.1.4 and it is working with one exception, The logging function
is not working. I have run ckconfig and that looks ok. I am using the
sample ftpaccess files and so on. I have used various flags in inetd.conf
and still no logs. Can anyone give me a clue as to what is wrong and where?

Hi everybody,
I noticed very old STOR commands with 'ftpwho' like (today) :
24814 ?? IW 0:00.35 pppK13002.micronet.fr: bigboss: STOR Index.html\r\n (
bigboss 24814 0.0 0.0 452 20 ?? IW 4Mar97 0:00.35
pppK13002.micro
^^^^^^
For the moment, I need to manually kill them.
Is there is any patch for wu-ftpd-2.4.2-beta-12 to solve this problem or will
I need to make a cron to automatically kill them ?
BTW, could you explain me why this version of wu-ftpd on a HP-UX 10.10 system
gives a non-easy readable output :
1 S 0 17180 1269 0 154 20 3a4c400 45 390ef68 ? 0:00 ftpd
Is there any configuration to change that ?
Thanks in advance for your help.
Gildas.

I have it running on an AIX 4.1.5 system and don't have a problem. It
logs some stuff to syslogd and other stuff gets logged to the xferlog
file. Which logging function do you mean? I have this in my ftpaccess
file:
log commands real,guest,anonymous
log transfers anonymous,guest,real inbound,outbound
and they work fine. Commands get logged to syslog, and transfers get
logged to the xferlog file.
Here's a web page that shows what I did to get it working:
http://www.pcc.com/~jay/src/networking/wu-ftpd-2.4/ORIGINALS/
I don't know if that will be any help for you.

Subject: Regular expressions in "noretrieve" directive.
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
We have been bothered by software pirates lately who use our anonymous ftp
site to distribute pirated software. We have had two publicly writable
directories in the anonymous ftp area /pub and /incoming, traditionally used
for downloading and uploading respectively. To eject the software pirates I
would like to enforce that tradition and deny uploading into /pub and uploading
into /incoming. The first is easy with the context of the ftp daemon. However
there is no explicit command in wu-ftpd to deny downloading from a directory.
There is the noretrieve command but that only denied downloading of individual
files -- as "man ftpaccess" says "No globbing is done." What I have now done
is to patch wu-ftpd-2.4.2-beta-13 to allow the use of globbing in the noretrieve
command.
I know that the traditional way to handle this is to make /incoming and the
files placed there unreadable by the ftp daemon. However I believe that using
this hack to ftpd is easier on legitimate users. Making the directory
unreadable complicates life for the hackers but does not stop them -- they
still would know the name of the files they placed there and can report them
as such to their hacker bulletin boards. Making the files themself unreadable
is a solution more appropriate for an institution where a single person with
appropriate privileges picks up the incoming files. I would like any user with
an account here to be able to pick up files for them with no special
arrangements. On Unix is it easy to make file readable by only a person or a
group but hard to arrange permissions make it readable by everyone except by
the ftp daemon. One could arrange to have a daemon move incoming files to an
area inaccessible by anonymous ftp and open up the permissions on the moved
files. Still, I believe that handling the problem within the ftp daemon is
easier for the legitimate user to understand than such a scheme that moves the
files to who-knows-where.
I consider this patch a hack. I believe that the proper fix would implement a
"download" command with the same syntax and options as the present "upload"
command. Still, this patch did the job and was quick to implement.

I do this using the following line in my ftpaccess file:
upload /export/ftp /pub/incoming yes webmaster webmstrs 0660 nodirs
This sets all files loaded into the incoming directory to be owned by
'webmaster' and placed in the 'webmstrs' group. The permissions on the
files are set to 660, which means that the webmasters can read the
files, but no one else can. This prevents FTP from passing the file
back to anyone requesting it, even if they do know the name.
No hack was required.

I've read
http://www.landfield.com/wu-ftpd/docs/anonymous-ftp-faq.html and
I've done searches on the archive and I still can't find how you do
multiple anonymous accounts, one for each domain that is virtual. I have
the virtual stuff all running and that is fine. and I have anonymous
working for my domain, but is there a way of having domain2 log into
/usr/ftpusers/domain2 and have anonymous goto
/usr/ftpusers/domain2/ftp/pub?
thanks

Hi,
I just got the package and like in Beta 12 above doesn't work, I put
this in ftpaccess file:
log commands anonymous,real
log transfers anonymous,real inbound,outbound
I start ftpd in inetd.conf like this:
ftp stream tcp nowait root /usr/sbin/tcpd /usr/sbin/wu.ftpd -ai
my question: Is logging working for anyone ? Or is it not working at
all ?
thx for clearing this up

I did a similar patch a while ago when we split our ftp site into to parts.
(we found that our games section was being completely overloaded by people
downloading from overseas. We split the site into 2 sections, and although
they were mounted on one disk, people connecting to ftp.is.co.za couldn't
download from the directory and were sent a message to connect to
gamesdomain.is.co.za)
I also set so that you can't do transfers of files in /lib, /etc, /bin and
the rest. This could be useful, I spose.

I would think you could use something like:
upload /ftp /incoming yes ftp ftp 0004 nodirs
Unreadable by user ftp or group ftp, readable by everyone else.

The "-i" flag will be overidden by the "-a" flag.
Try using:
/usr/sbin/tcpd /usr/sbin/wu.ftpd -la
Hope that helps.

Hello all,
I'm running beta 13 under a BSDI 2.1 system, and I have several
virtual ftp hosts. The one problem I have run into is this:
All of my virtual ftp hosts accept anonymous ftp. How can I
configure one of my hosts to deny it.
Thanks in advance,

Once again, a period of frustration leads me to tinkering... ;-)
There are quite a few things that would be nice to have supported in
virtual servers. In the current baselined version, virtual servers
are only partially supported. The current implementation of virtual
servers only supports setting
- the root ftp directory,
- the log file and
- the banner.
All other directives in the ftpaccess file have to be shared globally
across all virtual servers. A real limitation if you wanted to have
different features supported by different servers...
In reviewing how virtual servers were implemented, I reread the virtual
server setup FAQ. There are two different methods documented. First is
the VIRTUAL support that is a part of the current beta-13 baseline. It
only supports the three ftpaccess file directives listed above. The other
method is the alternative method which requires tcpwrappers. It then
dawned on me that the answer to completely supporting virtual servers
was right in front of me.
Why couldn't I simply specify which ftpaccess file to use ? If I could do
that then maybe it wouldn't be a major task to add support for all access
file directives (which is basically what Karl achieved using tcpwrappers).
If changes were made to access_init() to determine which ftpaccess file to
use (instead of the hard-coded _PATH_FTPACCESS) then all the existing acl
features could be available to each individual virtual server. No need for
tcpwrappers. Support for completely independent access files should be easy
to add.
So that's how I spent Tuesday night... ;-)
Here's what I did... First I created a new file called "ftpservers" defined
by the path _PATH_FTPSERVERS. The file is optional so if it's missing, the
original ftpaccess (_PATH_FTPACCESS) file is used. An ftpservers file looks
like the following:
#
# ftpservers file
#
# Format:
# ip-address associated-ftpaccess-file
#
# ftpaccess file for the landfield.com domain
#
208.196.145.2 /etc/ftpd/ftpaccess
#
# ftpaccess file for the faqs.org domain
#
208.196.145.20 /etc/ftpd/ftpaccess.faqs.org
#
# ftpaccess file for the some.other domain
#
208.196.145.55 /etc/ftpd/ftpaccess.some.other
In access_init() I included a call to a new function "getaccessfilename()"
that looks up the access file based on the socket address the user is
coming in on. The found file is then passed to readacl() as the hard-coded
_PATH_FTPACCESS was before. Other than a minor tweak, that was all that
was needed. Complete virtual ftpaccess support... I am currently running it
here and it seems to work just fine. It is amazing how clear things become
when you take the time to study the code... ;-)
I made the associated changes to ftpshut, ckconfig and my new ftprestart.
The only program in the wu-ftpd suite that does not have the new virtual
access file support is ftpcount. Have to get to that tomorrow night. ;)
Besides allowing any virtual server to be able to set and use any ftpaccess
file directive, an additional benefit is that any future extensions Stan adds
to the ftpaccess file will be automatically supported for virtual servers as
well. Free.
All my changes were made to the latest beta-13. (If Stan brings out beta-14
in the next few days, I'll be re-incorporating them into that. It'll be
much easier now. ;-))
I plan on sending these to Stan for inclusion in a upcoming version (may even
drive to Houston to bribe him with a refreshment or two. ;-) Dallas isn't that
far away...) I understand the situation he's in with trying to get beta-14
out and then work on a complete release. Because of that I'd like to see
another site or three run these changes before I send them to him.
If you're running a virtual server configuration and need more control
over your individual virtual servers, have I gotta patch for you... ;)
Anyone interested in running theses changes, just ask. I'll be glad to supply
them to you. I also promise to support you actively during the beta of my
beta. ;-) Thanks.

I munged this a bit on our server (ftp.is.co.za and gamesdomain.is.co.za)
compiling 2 versions of wu-ftpd and modifying inetd (I didn't do that bit)
so that it would choose which ftpd to start depending on which IP alias
was connected to. The 2 compiled versions had different #defines for the
config files in them. The inetd is at
ftp://ftp.is.co.za/private/oskar/inetd.kezia.tar.gz
It is based on the linux inetd.
The program "netd" in inner-apps-0.05.tar.gz
(
ftp://ftp.is.co.za/linux/networking/ipv6/inner.net or
ftp.inner.net/pub/ipv6) is designed to work with ipv6, but does this
elegantly with a config file similar to xinetd.
Currently (as of B12) the way that wu-ftpd reads the config files is a mess...
it's a good idea, but if you make a spelling mistake in the config file,
it just gets ignored. This could be fixed by creating some kind of list
of valid tags (so at least the first entry, such as "class" or "message"
would be checked)...

Plus the readme files, the ownerships, the permissions. I guess either I am running tcpwrappers without knowing it, or I am not sure what you are missing here. I can't think of anything extra that is missing. Could you tell me what else you get from this?

# Currently (as of B12) the way that wu-ftpd reads the config files is a mess...

# of valid tags (so at least the first entry, such as "class" or "message"
# would be checked)...
While I don't like the way things can be ignored, I'm hesitant to load up
the server with error checking that has to be done on every connect. That
could be a bit of a performance problem....
What would make sense though is to put that kind of checking in a program
outside the server. If ckconfig were expanded to be smart about file formats
and did serious checking then an administrator could check the formats after
any changes. If the admin didn't use it to verify the syntax, well, that's
their problem.
Does this make sense to others ? If so I'll play with ckconfig a bit.
(The name conflicts with another ckconfig program on the net but that's
another issue... ;-))

:-) Ok. maybe I didn't explain it correctly. Currently the virtual server
options which are supported in the ftpacces file is the virtual root directory,
the banner message file to be supplied for that virtual server and the logfile
in which to put that virtual server's transfer logs in. ALL the other setting
in the ftpacces file are shared across all the virtual servers. Currently
you cannot deny access to unresolved IP addresses in one virtual server without
applying that policy decision to all virtual servers served on that machine.
You cannot have different directory aliases, email addresses, cdpaths,
passwd-checks etc.. They must all be shared. Now they don't and the site
admin has real granularity when it comes to setting up a virtual server.

I'd like to know if anyone out there has been able to get the

there anything else that I need to configure for this thing to work
correctly?
Also, I have noticed the time stamp reported by the dir command

and the file timestamp is correct when I log into the machine via telnet.
Any Ideas??

Hopefully this hasn't been asked a million times but the FAQ nor the ftpd
documentation make any reference to this (I hope so anyways). I am exactly
how in.ftpd deals with each connection. I was under the impression that
the in.ftpd daemon sat around waiting for connections and then spawned new
ftpd sessions as needed. Is this correct?
Our ftp server "hiccuped" last night and stopped accepting connections.
When we checked out the server we noticed a whole pile of in.ftpd processes
sitting around. Shouldn't there only be one in.ftpd process? Any ideas
what would cause multiple instances?
Thanks for any feedback.

You don't say what version of the program you're using, or what OS you're
running on, or whether the problem occurs for both anonymous and regular
users, so it's a bit tricky to comment.
However, I know that under Solaris 2 if you don't include the relevant
timezone information under your anonymous root directory, then anonymous
users won't see the date corrected for the timezone. Sounds like this could
be your problem. On my Solaris 2 box, this meant having a
~ftp/usr/share/lib/zoneinfo with appropriate contents.
Check the ftpd man page originally supplied with your OS and see what it
says about this. It should tell you what to copy to get an anonymous set
up working correctly.
As far as logging transfers goes, there are two things to check that come to
mind...
a) Have you put a line in your ftpaccess file to tell the server to log
transfers ? (eg. "log transfers anonymous,real inbound,outbound")
b) If so, are you starting the server with the -a option ? Without this
(unless you have an old version of the program) it won't read your
ftpaccess file, so it won't know it is meant to do any logging.
Hope this helps !
Cheers, Bob

While I suspect that the overhead for syntaxing the command file would not
really be all that significant, it does bring up the issue of how the daemon
would respond if it found a problem... Not much use telling the client, as
they don't have any control over the file in the first place - nor would
they be expecting any feedback of this sort.
And I do agree that syntaxing the file everytime the server is started should
not be necessary, whatever the overhead - it shouldn't change often, so the
process you've suggested or running ckconfig to check the syntax immediately
after it has been changed makes a great deal of sense.
I think the suggestion is a good idea. You could do this in ckconfig, or
perhaps in separate program, since you probably don't need to check the
rest of the configuration every time you make a simple change to the
ftpaccess file. (Or this could be a command line switch to ckconfig.
Whatever.)
Cheers, Bob

This could be a setproctitle/SPT_TYPE issue. If you're running under IRIX,
set SPT_TYPE and do a clean make. This should clear up timestamp issues (I
assume the timestamp you see is GMT.)

No. inetd does the waiting for connections bit and spawns an ftpd when
needed. wu-ftpd itself has no idea of this 'accept()' and 'fork()'
stuff to put it mildly.
[ This goes back to the time when memory was expensive, and network
delays where enough to cover for fork-delays. pre-forking daemons didn't
exist, inetd just sat (and still sits) there waiting on all those ports
to see which daemon to kick into gear ]

Hanging ftp processes maybe ? Or a real big interest in your ftp site
all of a sudden (CHECK your incoming for hidden subdirs). There has
been some talk of improving timeouts in certain spots of wu-ftpd.

Subject: vulnerability exploit in wu-ftpd
MIME-Version: 1.0
Content-Type: TEXT/PLAIN; charset=US-ASCII
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
Recently, we were attacked by an individual who was in posession of a copy
of a unix shell script which exploits a hole in wu-ftpd. This is *not* the
same vulnerability as described in CERT advisory CA-95:16.wu-ftpd.vul, which
refers to a misconfiguration of _PATH_EXECPATH. Our _PATH_EXECPATH is
configured correctly.
I've just now subscribed to this mailing list, so please forgive my
ignorance of previously discussed issues.
The host which was attacked is a Sun Ultra running Solaris 2.5.1. The
version of wu-ftpd is wu-2.4(4) which was compiled by us on 13-aug-1996
from sources which were available around 8-may-1996 from the wuarchive site.
The perpetrator had a script named "over" which had the capability of
overwriting any file on the system. Some header comments from "over"...
# exploit a bug in wu-ftpd to create a file anywhere on the filesystem
# - files that already exist will be overwritten, but they won't
# be writable.
#
# tested under Solaris 2.5
#
# James Abendschan
[email protected] 16 Oct 1996
#
I will not release the details of the script for the usual security reasons.
The perpetrator either maliciously or stupidly overwrote the passwd file
on this unix host, rendering the system inaccessible and causing about
a half day's loss of service to the campus while we traced through logs and
directories discovering what had been done and what had been damaged.
My questions are directed mainly to the maintainers of the wu-ftpd software:
1. Is this a known bug?
2. If known, has it been fixed in the current 2.4 patch release?
Thanks very much.

Larry,
I must profess that without seeing the details of
the exploit it would be difficult to tell if the
exploit had been addressed in a current release.
The current release of wu-ftpd is 2.4-beta12 which
has a rather large number of fixes from just the
2.4 release.
Can you check and see if you are running the or one
of the latest beta wu-ftp versions ?
I would be interested in double checking it since my
systems are Solaris 2.X running Wu-ftpd 2.4.X
TIA
Later.

If this is *not* a CERT-advised exploit, have you reported it to them?
I'm sure they could tell you if it's been reported before, and if so, what
fixes are available.

Not to nitpick, split hairs, split beer atoms (like Weird Al Yankovic), or
anything, but...
actually, latest is 2.4.2-beta 13. Beta 13 has been out for some time now.

Folks, I can't figure out how to make the right times show up in
xferlog under IRIX 6.2. I've copied /etc/TIMEZONE to the etc under
ftp but that doesn't help. The FAQ doesn't mention IRIX at all.
Thanks for any help.

Under IRIX, you don't actually need timezone info in your chrooted
environment. What you do need to do is change SPT_TYPE to SPT_NONE before
you compiled the server. IRIX doesn't have the concept to setproctitle (at
least, not yet) so it causes garbled timezone info.

Security through obscurity will get you nowhere
This ain't a cracker list, if you don't want to release any details
then why posting ?
Seeing this crap ... hmmmmm

I believe what you are reporting is the fact that
wu-ftpd can core dump and it will core dump as root.
And of course it will follow any symbolic links
the easiest way to make wu-ftpd core dump
is to issue a PASV command without doing the user/pass first
ex:
telnet locahost ftp
200-
200- ....
pasv
the server will core dump
if you know where just make a symlink to /etc/passwd
or
the bug in ftp_popen() if the argument is over 100
do something like
ls a a a a a a a .... over 100
or
site exec index a a a a a a a a a a a a a over a 100 args
the server will crash also
All those issues and more that you are not aware
where corrected in the beta release's
Just upgrade the server

Post the details or don't bother
Security is a big concern to us, no need to raise

How do *you* know?
How do you know that I'm *not* a cracker? I didn't have to present
and credentials to join this list, and given that wu-ftpd is a
very widely used piece of software, and has been a vulnerable
piece of software in the past, you can bet your best boots that
there are some, er, interested parties on this list. (hI d00dz :)
If I were a clued up cracker, I'd be the first to subscribe to
this list, as many web server lists as possible, bugtraq, the
CERT list, the greatcircle firewall list, and so on. Then I'd
just *lurk*, thanks very much :-)

I got a copy of the script off the net (amazing what you can find when
you look). Alain was right. It was a script that attempts to exploit
the core dump symlink problem using PASV. I was unable to get the server
(beta-13) to core dump using the script.
Alain's advice should be followed ... Just upgrade the server...

because wu-ftpd chroot's to ~ftp everything is absolute from that point:
example:
ftpaccess:
message /usr/local/msgs/ftp.welcome
would be ~ftp/usr/local/msgs/ftp.welcome
~ftp is /home/public/ftp the location of the ftp.welcome file would be:
/home/public/ftp/usr/local/msgs/ftp.welcome

i checked /etc/ftpaccess and the line "log ..." is there. i also changed
the line "message /welcome.msg login" to "message /home/ftp/welcome.msg
login" --- but when i checked it again (ftp'd to the server, the
welcome.msg doesn't appear and it doesn't log to /var/log/xferlog).

I have exactly same two problems when I have tested wu-ftp and
forgot to change /etc/inetd.conf. There was still link
to old (if you replace it) ftpd (/etc/ftpd -> /usr/sbin/ftpd).
Because my wu-ftpd is placed in /usr/local/etc/ftpd, I change
this line in /etc/inetd.conf so.
Or you have set flag to enable/disable ftpaccess file (-a/-A)...?

Subject: Problems w/ anonymous
X-Sun-Charset: US-ASCII
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN
I am currently configuring the daemon on a Sun Solaris 2.5 platform w/
anonymous activated. The server runs fine from a unix command line client
when connecting to any account including anonymous. However when an ftp
frontend (ie Netscape, WS_FTP, etc ) is used as a client and you connect
to the anonymous account the client does not appear to obtain the directory
listing and display it. However using the same client applications and
connecting to a valid user account all works well.
Any help would be appreciated.
thanks

Hi,
AIX (4 at least) does not need the CANT_BIND directive.
In fact, using this and the VIRTUAL define will cause some
problems for clients behind a firewall, since they get some
responses from the virtual address, and others from the
"main" address.
Just thought you might want to know this to update the config.aix
file.
Many thanks for an incredibly useful program!

I fixed it for AIX3 in the first place (buggy kernel anyway).

What does your line in inetd.conf look like? Are you sure that you canged it to point to the new wu-ftp after installing it? Did you use the -a option in it? Did you do a kill -HUP on the PID of your inetd to restart it (or reboot the server)?

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

Hi there,
I found a small problem (aka very tiny bug!) in extensions.c when using
two cookies %E on the same line, like this:
%E ** %E
it prints (on the left side is french, that's not the bug ;) ...
****
Pour de plus amples informations ** For more informations, contact us via
contactez nous par courrier a ** via the following electronic mail
l'adresse suivante: ** address:
**
[email protected] ** ddress:
****
I found one way to fix this problem:
In file extensions.c in msg_massage() add entry = NULL; at line number 285
}
while (*outptr)
outptr++;
entry = NULL;
}
This is to make sure that the 'entry' var. will be set to NULL if
getaclentry("email", &entry) is called twice within -1- line aka
two %E cookie on the same line.
You could always add the entry=NULL on line 211 right after calling
getaclentry.
If you follow up on this mail please email me a copy to
[email protected] since I don't always have the time
to read all messages in this list.
thank you,

Hello, all!
I'm working on using "guestgroup" with wu-ftpd beta 13. Because of some
kind of Solaris (2.5.1) only bug, files uploaded into user created
directories do not get set to the user/group ownership specified in the
ftpaccess file (yes, I've reported this bug).
Evan Champion once offered to send out patches that addressed this issue
by using something called :user: and :group: tags. He was waiting for
beta-13 release, I got assigned to other things and we haven't connected
up since (I sent him personal email before trying here now).
Does anyone have these patches for previous releases or applied them
to the current release? I really need to get the dir/file ownership
issue resolved.
Thanks!

(and yes, I'm back to working the Solaris How-To Guide this week :-)

this is on Digital Unix 4.0, wu beta 13.
I have some accounts set up like this:

anyway, kuvasz can log in and do all the stuff they need just fine. they
can also cd up one directory, and then up, again until into /. Root, for
them, does not seem to be /usr/ftpusers/kuvasz and the directory ftpusers
is owned by root, grouped by system, of which kuvasz is not a member.
Am I truly missing something here (since it is 12:01est now :-)) or does
chroot not limit people to what they can cd into?

Becky,
is group 100 defined as a guest group in ftpaccess (only guest groups and
anonymous get chrooted).
PS if a user kuvasz does cd .. from his home directory (as defined below)
and does pwd, the response is / are you sure they get to the system root?

Hello,
I just subscribed to this list server because I have just set up a Linux ftp
server. We needed one machine to respond to 3 separate IP address as if it were
3 separate machines. I used Brian Kramer's patch to setup virtual ftp server's.
It can be found at
http://www.westnet.com/providers/multi-wu-ftpd.txt.
Here's the short version:
1. Setup Virtual IP Addresses
2. Install Brian's Patch ( patch < multi-wu-ftpd.txt)
3. I needed to manually change the make file because the patch didn't change
it and because I needed to add an additional to get wu-ftp to compile with
Linux. I changed line 4 from
CFLAGS = -O2 ${IFLAGS} ${LFLAGS}
to
CFLAGS = -O -DVIRTUAL -DDEBUG ${IFLAGS} ${LFLAGS} -DDIRENT_ILLEGAL_ACCESS
4. build lnx, build install
It works like a charm.

no, what I meant to say was, I can log is as kuvasz, and the home is
/usr/ftpusers/kuvasz. I can then cd up one and pwd, the directory is
/usr/ftpusers, etc...

Hi
I have heard rumours that wu-ftpd falls over when you have about 3000
people using it. Is this true. If so what can I use.
Or can I fix it
Thanks

This is probably true 'cause wuftpd depends on locking a file in order to
get its access information. With thousands of users I would expect wuftpd
to effectively deadlock. I had been putting some work into a more reliable
method of doing this but I'm not on the developement team so anything I do
isn't likely to be incorperated into any release.

When he said 'falls over' did he meant ..
machine going to grinding halt because of not enough memory ?
out of swap ?
TCP/IP traffic jam ?
machine can't keep up ?
limited by some system specific constant(file des. # of process, etc ..)
not enough mbufs ?
.. or design flaws in the code ?
Before reaching 3000 ftpd processes, I would expect other
break down .. No ?

I didn't have to go to thousands to have deadlock, after 100 or more
I got, in syslog, the wonderfully informative:
sleeping: fcntl lock of pid file failed:
and ftpd processes looping cloberring syslog
Probably the fact that /home/ftp was NFS mounted didn't help.

I've patch mine to bail out after 300 iterations, which is eternety
to a normal human.
Curious to hear your approach.

Long time no talk :) Many thanks for the snprintf stuff! It's saved me
more time than I can count.
You'll have to wait a bit, but maybe this time next week I'll have a test
setup running.

I'm no regular expressions guru so I'm enlisting the help of someone
who can help me to modify this path-filter statement with the correct
regex syntax to allow spaces in uploaded filenames, except no spaces in
the beginning of a filename:
path-filter anonymous /etc/pathmsg ^[-A-Za-z0-9_\.]*$ ^\. ^-
I probably want to allow % in filenames too. Thanks. I haven't seen
anyone asking about this in the FAQ or the list.

I just installed wu-ftpd on our Sun Solaris 2.5 systems. When anonymous
users log into ftpd, the time stamp on files are all off by 4 hours. It
appears to think it's in a different timezone.
When regular (not anonymous) users log on, everything is OK.
What do I need to do to fix this?
Thanks.

I bet you have to copy everything in /usr/share/lib/zoneinfo to your ftp directory's usr/share/lib/zoneinfo directory. There's documentation that comes with the wu-ftpd source to tell you how to configure your ftp directory, specifically the INSTALL file, which tells you in line 13 that you have to do this. Your ftp directory functions as a completely separate, mini root directory for security reasons when anonymous users log in. When normal users log in, they use the real root directory as their root so they won't experience this problem.

I had this problem also, then I found that you need to include in the ~ftp structure
a copy of /usr/share/lib/zoneinfo. I just copied the structure from the real side to the
chrooted side for ftp.
hope this helps...

Subject: idle timeout

Is there a way to make a different idletimeout for each class? Like the
anonymous ftp. I have a web page that links to quite a few files on the
ftp server. For some stupid reason, it appears that netscape isn't
properly logging out when the file is done, so it just sits there until
idle timeout (thus taking up the high demand spot) I thus edited inetd
and added a -t 60 giving it a 60 second timeout. Unfortunately, this is
quite anoying for me and the rest of the normal ftpgoers. Is there any
way to get around having a 60 sec timeout on all users, or might I suggest
an implementation in future vers...

yes, I've notice this also. Netscape doesn't seem to follow the Web
browser idiom "one file, one connection". But when you think
about it, it's not that bad, it puts less load on the server.
Before, every click was a fork()/exec() to inetd.

'Normal' ftp user .i.e "real ftp client" :-)
can reset the idle time up to an upperlimit
ex:

or if the ftp client don't understand site
ftp>quote site idle 900

Hmmm - maybe you're right about the idle sessions. It would give inetd a
nice break. I've had relatively major problems keeping inetd working
correctly. Every few min (esp with high users) I have to hup inetd to
keep it going. I always get
inetd[123]: ftp/tcp server failing (looping), service terminated
and I'm assuming that it is the result of too many requests coming in and
not enough system resources to get them open fast enough (the stupid
incredibly slow ide drive.) As far as the rest goes, I don't have a patch
but might decide to look into it and I will gladly email academ. Thanks
for the feedback...

Right and under Solaris you also need the /etc/default/init which tells
the system zonetime:
This is what I have in mine ->

you have a busy server :-)
on Solaris, and probably others, you can change this interval to
a higher count.
start inetd like this
inetd -r120 60
by default, the man page says 40 per min(-r40 60), grossly
not enough for a busy server.
On SunOS-4.x you have to apply a patch or compile one yourself
You'll find a usable version on GNU(inetutils.tar.gz) or in
the *BSD src.

Very.
I should note that this kind of thing is either global (ie starting inetd
with those flags) or on a per-service basis by making a small change to
the line in inetd.conf for your service (in this case, ftp).

Well, unfortunately I'm running linux and the inetd that's installed here
(I'm assuming it to be current -- where can I get latest) doesn't allow
the -r option (only -d). I also read the man page and attempted to edit
inetd.conf and hup it. I tried both changing nowait to nowait.max120 and
nowait.max 120 - both were unsuccessful and would refuseall connections.
If anyone could give me a little more help I'd appreciate it :) Thanks
again.

Even though I'm quite the computer-nerd, I thought of a different
meaning of 'locking user homes' then having to do with homedirs.
Anyway : you'll have to define guest users. Read the guestgroup howto,

Subject: ftpd corpses piling up

I know this has been mentioned before- I just went through my saved list
messages and found a lot of questions on it but no answer...
I have a situation where, I think under certain abnormal TCP disconnect
conditions, ftpd processes will be left permanently and uselessly dangling.
Eventually enough of these accumulate to fill the class and lock everyone
out. I looked at the code and it seems that the server should time out
after 900 seconds and exit. So now I'm thinking it must happen during file
receive? Before I fire up the debugger I'm hoping someone has some clues on
this. BTW, I am running 'stock' wu-ftpd 2.4 under AIX. I do plan on
upgrading to the latest at some point, but I've some custom authentication
stuff in there and it would be more effort than I can handle right now to
move it. I would rather just fix this one bug for now..
Any help would be very much appreciated.
Thanks

What about nowait.120? I think that's what you were looking for - ie
'max' isn't a keyword, but rather, a number that you substitute whereever
you see the 'max' parameter mentioned. Then after making change, do a
killall -HUP inetd for it to take effect on *cough* *cough* Linux *cough*
machine. There, I said it. ;-)

I know this is a bit off topic, but does anyone out there want to host a 5

You can have wu execute a chroot if you put a period into the passwd path
for the user. Ex: user:x:210:100:::/usr/home/./ This makes /usr/home
apear to be / . However, for this to work you'll have to create a dev,
etc, and bin dir... I could be mistaken, but I think that's what you'll
need. In the dev you need tcp, zero, and udp; in the etc a group and
passwd file (not the ones in /etc) and in bin you'll need ls.
I don't quite remember all of it, but I think that'll get you close.

Greg,
Its a bit more than stated below.
You use guest group accounts which get chrooted to the home directory (any
path beyond the /./ is the directory they get defaulted too
eg user:x:210:100:::/usr/home/user/./public_html
will cause the user to get chrooted to /usr/home/user and deposited in the
public_html subdirectory.
You create a group lets say guests and in the ftpaccess file you define that
group as a guest group.
eg
class guests guest *.some.domain #defines the members of guests
as having class attributes of the guest class (attributes the get assigned
to the class guest in ftpaccess)
guestgroup guests #defines guests as a guest
group (so they get chrooted).
