Hello,

I'm running Linux 2.0.30 and wu-ftp 2.4.2-beta14. I'll like to find out how to
get chmod to work when I'm using a windows ftp client like the simple Windows
95 FTP.EXE, or CUTEFTP. I tried putting chmod into my FTP-EXEC directory as
well as /bin of my guest accounts, but it still doesn't work. When I use unix
ftp, no problem doing chmod...its the windows clients which don't work. Any
idea, please let me know!!!

Thanks

Hi. I have looked over the man pages, and I think all the relevant docs
and still can't seem to get the right answer.

Here's the problem:

a) system is a Linux 2.0.30 machine.
b) compiled 2.4.2 beta 14 and installed fine.
c) got IP alias functioning fine.
d) set up a virtual host (foo.com) on the machine (www.foo.com working fine).
e) set up the virtual ftp and the banner and root works fine.
f) I have the following definitions:

/etc/passwd:
foo:<passwd>:509:505:username:/web/./foo.com:/bin/false

/etc/group:
foo::509:foo
client::505:foo

g) Here's the ftpaccess file:

===============ftpaccess==================
class all real,guest,anonymous *
guestgroup client
email root@localhost
loginfails 5
readme README* login
readme README* cwd=*
message /welcome.msg login
message .message cwd=*
compress yes all
tar yes all
delete yes guest,real
chmod no guest,anonymous
overwrite yes guest
overwrite no anonymous
rename yes guest
rename no anonymous
log transfers anonymous,real,guest inbound,outbound
shutdown /etc/shutmsg
passwd-check rfc822 warn
virtual 1.2.3.4 banner /var/ftp/foo.com.welcome.txt
virtual 1.2.3.4 root /web/foo.com/
===============ftpaccess==================
h) the /web/foo.com is chown foo.client.
i) there is a bin, etc, lib dir in /web/foo.com with all the files
from /home/ftp/xxx copied in.

Problem:
a) When I do a ftp to foo.com, the banner comes up correctly.
b) Now, when I login as foo, I get in fine, but when I do a dir, I see
nothing. I can put, get, dele and mkdir. But I cannot see the listing.
c) However, instead of logging in as foo, I login as anonymous, I get
to see the dir listing. Really bizarre.

Appreciate any help.

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 little direct experience with 'site exec', but you may have to use
'quote site exec' in some cases. I don't know why you have to do this in
some cases and not others.

I think you'll find that this is a client thing. Some clients (eg. HP-UX)
do support the "site" command, whilst others (SunOS 4, Solaris 2) don't.
For those that don't, you can usually get round this by using "quote site"
instead.

Subject: ACL and "autogroup/class" support
X-Mailer: MH 6.8.3
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

In my recent forays into using WU ftpd I came across tantalizing
references to support for "access control lists" (ACL's). I'm
wondering if these features have been more fully developed in current
beta's (or if they were already there and just needed more documentation).

Could anyone here enlighten me regarding this? Does wuftpd support
ACL's? If so, how?

Another question I had amounts to this: I misunderstood the
"autogroup" directive (ftpaccess). What I want is to be able to
assign someone to a group based on the "class" that they are in --
i.e. if they came from outside my domain I'd like to "classgroup" them
to "outsider" I'd also want to provide a way to deny "outside" access to
members of an "insider" group. The concern here is to enforce a policy that
employees can only access their account from within the intranet --
both to discourage them from passing their password over the Internet
(knowing that most of them will use the same password for this xfer
account as they do for other, more sensitive internal services) -- and to
prevent them from creating a "covert channel" (or requiring that they
act in collusion with specific outsiders in order to accomplish that).

Let me back away from these specifics for a moment to describe my
real requirements.

I need to provide an organizational file transfer point between
employees (insiders) and external contractors/vendors (outsiders).
There is NO anonymous FTP (in fact there is to be NO anonymous ANYTHING
at this site -- that is a key point of their computing policy).

[Please: no debates on the degree to which this policy can or cannot
be enforced in a TCP/IP intranet environment -- I'm aware of some of
the limititation of the protocol suite -- and they aren't germaine this
this discussion]

Ideally we'd be able to set up each user with an account -- and an
easy mechanism to permit or deny each other user 'write' access to a
given directory. Ideally this would also prevent the user from given
read access to any other users (i.e. I can specify who gets to put
stuff into my directories -- but I can't let anyone else read
my directories or files). Also it would be nice if filename collisions
were transparently dealt with (a la SUNIQUE -- or store with unique filename;
but without requiring client side support for this feature). Each file
deposite (put) on the side must clearly indicate (via ownership) the
identity of who put it there. it would also be nice if whole directory
trees could be just "dragged and dropped" on the client side (again with
the server automagically creating a unique toplevel directory and
populating the structure under it.

Oh, yeah! They want it all to be accessible via standard FTP clients
(although they are willing to have the administrative (ACL's) stuff done
via HTTPS using web browsers (preferably with client-side certificates:
SSLv3).

That's the wishlist. The key requirements are:

No anonymous accounts
No "public" files
No way for outsiders to make files visible to outsiders
Accountability: no way to "forge" a file as being "from"
another account holder.

The key constraints are:

Must work with a variety of commonly available Windows (GUI tools).
Must not add any substantial administrative overhead
(to the sysadmins)
Must be sufficiently easy to use that users won't be inclined to
bypas it (via file attachments to e-mail -- which kills their
cc:Mail system for files of any subtantial size).

To be honest I'm not sure that any configuration of wuftpd will
meet these requirements and constraints. My client might be willing
to sponsor further wuftpd development (respecting the GPL, of course)
to make a set of modifications that would implement these features:
if we/I can agree on a feature set that would work and have some
assurance of timely delivery. (Yes, I'm NOT a programmer!).

My first take on this was:

have them all use PGP to encrypt the files TO the intended
recipient. This eliminates most of the problems since PGP's
encryption far surpasses their confidentiality requirements
(they're still passing the passwords of "outsiders" in
plaintext over the Internet). In introduces two problems:
requiring a specific client package for all sites, including
external and independent contractors (minor -- simple financial
issue), and it requires that the company institute a public
key (PK) management infrastructure (which leaves them fighting
over SKIP/ISAKMP/Oakley, LDAP, X.500 and all sorts of other
thus far unimplemented/undeployed "standards").

Personally I suspect that .ZIP with the "scramble" (encryption)
option would be adequate -- their confidentiality requirements
for this work are pretty minimal; the issue is more of
accountability and isolation from more important internal
resources.

Anyway, that's my problem. I look forward to any suggestions.

Hello,

I have been using wu-ftpd-2.4.2-beta-11 on HP-UX. I have some questions
on how the on-the-fly compress/uncompress utility works. According to
what I understood it is the ftpd_popen() function in popen.c file in
which the child process created by vfork() call does the execv() to
finally execute the compress/uncompress command. Does anyone can
explain this to me ?

Thanks in advance for your help.

Regards,
Harshal

Hi,

I've checked the archives and the FAQ, if this is a common question please
beat me up then point me to the information treasure chest.

I am running Version wu-2.4.2-academ[BETA-12](1) on Red Hat Linux 4.2, with
the installed RPM and shadow passwords. I can log in just fine (user
chrism has a group named chrism) but other users like joe (in the group
named "users") can't log in (login denied).

I'd appreciate a pointer as to what the possible problem could be.

Thanks,
Chris Magnuson

Oops. I forgot to say that I had already checked that.

(looking...)

Doh! Here's the problem. There is no shell specified in /etc/passwd.

OK, so here's a new question, is it possible to allow ftp access but
disallow telnet? Typically to disallow telnet you set the shell in
/etc/passwd to be something bogus.

Hello all,

I am about to install wu-ftp on a server which is currently running
anonymous ftp. Is it possible to install wu-ftp without interruption of
the current anonymous ftp services? Or will I have to shut down the
current services to install wu-ftp.

Thanks for any info.

Hi,

I have just mounted WU-FTPD V2.4(2) on an
AlphaStation running DEC Unix V4.0, with
the hope that I can record all ftp activities.

No errors were reported during the installation.

I then made a copy of the ftpaccess from examples
to /usr/local/etc and restarted inetd.

The ftp are working as expecting, but the logging
of these activites are not quite.

So far, inbound ftp to a real user is logged (on both
put and get), but inbound anonymous access is not logged.

Furthermore, no outbound ftp transfers initiated by
real users are recorded on the xferlog.

Could anyone shed some light to this?

Thanks in advance.

You need to install the latest version; there are many bug/security fixes.
May cure the log issues also.

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 a question which perhaps someone here can help with.

I am running beta 13 on a Sparc that is running SunOS 4.1.4 and I ma seeing a
difference in the times being reported back by the server when a user asks for
a long directory listing.

Example:

0) Here is the "ls" output when I telnet into the box:

d--x--x--x 3 root 512 Jun 9 18:22 bin/
d--x--x--x 2 root 512 Jul 25 1996 dev/
drwxr-xr-x 2 root 512 Jul 17 16:44 etc/
drwxrwx-wx 5 root 512 Sep 3 19:22 incoming/
drwxr-xr-x 2 root 512 Dec 3 1996 lost+found/
drwxrwx--x 2 root 512 Jul 17 18:39 outgoing/
drwxrwxr-x 4 root 512 Jul 21 17:20 public/

1) Here's what I get when I am logged in via FTP as "anonymous":

d--x--x--x 3 root 512 Jun 9 22:22 bin
d--x--x--x 2 root 512 Jul 25 1996 dev
drwxr-xr-x 2 root 512 Jul 17 20:44 etc
drwxrwx-wx 5 root 512 Sep 3 23:22 incoming
drwxr-xr-x 2 root 512 Dec 4 1996 lost+found
drwxrwx--x 2 root 512 Jul 17 22:39 outgoing
drwxrwxr-x 4 root 512 Jul 21 21:20 public

2) Here's what I get when I am logged in via FTP as a real user:

d--x--x--x 3 root 512 Jun 9 18:22 bin
d--x--x--x 2 root 512 Jul 25 1996 dev
drwxr-xr-x 2 root 512 Jul 17 16:44 etc
drwxrwx-wx 5 root 512 Sep 3 19:22 incoming
drwxr-xr-x 2 root 512 Dec 3 1996 lost+found
drwxrwx--x 2 root 512 Jul 17 18:39 outgoing
drwxrwxr-x 4 root 512 Jul 21 17:20 public

It looks like wu-ftpd is converting file dates & times to GMT when I open an
FTP session as anonymous. But when I open an FTP session as a real user, it
seems to report file dates and times using local time instead of GMT.

Is this supposed to be like this?

Shouldn't it always report dates and times in GMT to a remote FTP client, no
matter if they are a real user or the anonymous user?

Any insight into this behavior would be greatly appreciated.

I can't help you with SunOS, but under Linux I had to duplicate the
appropriate files from /usr/lib/zoneinfo into ~ftp/usr/lib/zoneinfo. (In
my case, that was Chicago, localtime, and posixrules...there may be more
or fewer files in your case.)

Once I did that, all the times were consistently in the Central time zone
for anon and real FTP sessions.

Good luck!

Hi all,

Is there a (simple) way to convert the name of uploaded files so that
space characters get changed e.g. underscore ?

(e.g. "my file.zip" should get changed to "my_file.zip")

Of course I could write a simple shell/perl script for this, but I'd
like wuftp to do it for me automatically... :-)

I have been looking through the FAQ and mail archive, but couldn't find
any useful info on this matter...

I would like a certain user to only access via ftp. I have done everything
to limit that. But I would also like this person's home directory to be
the only directory they are allowed to ftp in. Is there a way to do that
easily with wu-ftpd? I have tried /home/user/./ but that doesn't seem to
work. Any thoughts?

Please reply to : [email protected]

Hello,

I have been using wu-ftpd-2.4.2-beta-11 on HP-UX. I have some questions
on how the on-the-fly compress/uncompress utility works. According to
what I understood it is the ftpd_popen() function in popen.c file in
which the child process created by vfork() call does the execv() to
finally execute the compress/uncompress command. Does anyone can
explain this to me ?

Also can anybody explain me how to do on-the-fly compress/uncompress ?
I am not able to do it.

Thanks in advance for your help.

Regards,
Harshal

Subject: Xferlog problems on DEC Unix V4.0
X-VMS-To: SMTP%"[email protected]"
X-VMS-Cc: PCMC
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

Thanks for the responses from [email protected]
and [email protected] on the xferlog problems
that I have with DEC Unix V4.0 on WU-FTPD V2.4(2).

The problem was that only inbound ftp on a real user is
logged in xferlog, and I would like to see all transactions logged.

I have been suggested to pick up the latest release V2.4.2 (Beta 14)
and that I have done.

The installation on this kit however gave a couple of problems
that resulted in no ftpd being produced:

a. ./support/fnmatch.c contains an error inhibiting FNM_LEADING_DIR
and FNM_CASEFOLD from being defined:

#ifndef _POSIX_SOURCE
#ifndef FNM_LEADIND_DIR
#define FNM_LEADING_DIR 0x08 /* Ignore /<tail> after Imatch. */
#endif
#ifndef FNM_CASEFOLD
#define FNM_CASEFOLD 0x10 /* Case insensitive search. */
#endif
#endif

b. /usr/include/acl.h is expected but this file is now in
/usr/sys/include/sys/acl.h.

This may be caused by the fact that I am not using ACL or
C2 security.

Having gone that far, I have managed to compile and produce the
binaries. I ran bin/ckconfig which reports for some missing files
in /usr/local/lib/ftpd (as opposed to /etc defined in pathnames.h).

Anyway, I copied the doc/examples to /usr/local/lib/ftpd/ftpaccess,
ftpconversions and an empty ftpusers.

Having reloaded inetd, I found out that no inbound ftp is now authorised
(on real users, root, and anonymous). I got the username prompt but
they are all rejected with "530 Login incorrect" errors.

Outbound ftp seems to be working okay though.

Does anyone has any idea of what has gone wrong?

With tcp-wrapper I can control which IP addresses can access certain IP
ports. It also allows userid checking (only user anonymous from site
'x.y.z'), but it requires that the requesting site have an IDENT server
running, so it's basically useless.

Is there a way to get wu-ftpd to control access in this way (an access list
of sites to allow, disallow), and include userid level control?

What I would like to do is allow account access only from specified sites,
but allow anonymous access from all sites. I don't want "unknown" sites to
be allowed to attempt account logins.

Subject: Guest account setup scripts
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

Dear WUFTPD'ers,
Have looked at a lot of setup scripts but they are all for anonymous accounts.
Realize this covers most of the same setup for guest class account, but
a couple differences have been giving me problems. I presume that someone
out there....(big echo;-) has done this so was hoping for some advice.

1) Need to actually set a passwd for the guest class account, where
anonymous doesnt need one set. Problem is how to do this from a script,
preferably from Perl but ksh or sh would be fine ;^>
Cant get the UNIX passwd command on any flavors I have played with to
take program or file input so I can automate this step. Presume this is
security precaution, but is their some way to subvert this?

2) Thought I needed to add /./. to home directory in /etc/passwd file
after using adduser to create the guest class login. This is because adduser
wont accept a home directory argument with these trailing characters.
But it appears that I may not need to do this since I do want the guest
to be chrooted and to be logged into the home directory and this is the
default action? Is there any disadvantage to using what appears to be
the default action in all cases since this is what I setup with /./. anyway?

Any info or thoughts would be appreciated.
Thanx,
Roger A. Hanke

Sounds like you put the /./ chroot() stuff in the ~/etc/passwd???? The
chroot path and FTP group must go in /etc/passwd -- the real thing.

Hi...I've put the same entry in both /etc/passwd and the "local" copy.
would guestgroup being set to www and in ftpaccess and the user not being
in the www group in /etc/group have any effect? what else could I be
missing? thanks....

OK, here's my ftpaccess file question.
I'm running wu-ftpd on a debian 1.31 linux
box....I'm trying to set up the autgroup
option to limit a user to one specific partition
of the system....the man pages are kinda' foggy
concerning the actual syntax of the line in
the ftpaccess file. I set-up /etc/passwd
as indicated with the home directory as
"/whatever-partition/./". Can someone please
send me an example of the proper syntax and
do I also have to do a chroot ()????

Thanks.

In BSDI (v 2.1 and 3.0) the FTP server is invoked from inetd. The command
line there is default to not read the configuration file. In order for the
server to even look at /etc/ftpaccess, you need to change the line in
/etc/inetd.conf to have a command switch of "-a" instead of "-A" and it
will work.

Don't forget that in BSDI 2.1 with a dynamically linked ls, you will need
~ftp/shlib/libc_s.2.1.0 in order for it to properly give you directory
listings.

Hope this helps,
Andrew

Dear wu-ftpders,

We, the Computing Center of the Eindhoven University of Technology, administer
a anonymous ftp-server based on Version wu-2.4.2-academ[BETA-13]. Anonymous
local users( in domain tue.nl (131.155.*)) are chrooted to /tue-ftp. External
anonymous users are chrooted to /tue-ftp/ftp. The local users find in /tue-ftp
stuff that is meant for internal use only. We achieve this functionality by
applying a small patch to ftpd.c :

idefix.tue.nl# diff ftpd.c ftpd.c-new
1580,1583c1580,1591
< if (chroot(pw->pw_dir) < 0 || chdir("/") < 0) {
< reply(530, "Can't set guest privileges.");
< goto bad;
< }
---
> if ( hostmatch("131.155.*") ) {
> /* the root must be one level back (tue-ftp) */
> if ( chdir (pw->pw_dir) < 0 || chroot ("..") < 0 ||
> chdir("/") < 0) {
> reply(530, "Can't set guest (tue-ftp) privileges.");
> goto bad;
> }
> } else
> if (chroot(pw->pw_dir) < 0 || chdir("/") < 0) {
> reply(530, "Can't set guest privileges.");
> goto bad;
> }

When we upgrade to a new version of wu-ftp we have to apply this small patch.
Although the patch is small and easy to understand we would prefer to have a
configuration file a la ftpaccess e.g.

kind regards,

Ivan

Stan,

You might need to address this one.

It is also a valid compromise on Solaris 2.5.X running
2.4.2 Beta 14.

I was able to kill my system earlier today..the system
load just continued to climb until it crashed.

Subject: FTP compromise.

I found this today. Any comments?

BUG: wu_ftpd (all versions)

TESTED: BSDI 3.0 (all patches), FreeBSD 2.2.1

DATE: 15th Aug 1997

REPEAT BY: Log into a wu_ftp server (either anonymously or as a user)
and issue the command...

nlist ../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/
../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/
../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/
../*/../*/../*/../*/../*../*../*

DESCRIPTION: You can severly compromise the ftp servers performance.
This command will create a HUGE directory listing, no
matter how many files/directories are in the current
directory (this is recursive).

CONSEQUENCES: These vary. On my FreeBSD 2.2 box I was able to eat up
all memory and swap memory until the kernel spewed
"out of swap space" errors and killed a few processes.
It also eats up all available CPU space (up to 99.22%
on my box). If repeated a few times you will no
longer use up swap space and the processor usage will
rocket and stay there for quite a while (hours). Since
the ftpd program is still processing the command your
ftp session will not idle timeout. However, if you
do decide to kill your attacking ftp session, ftpd
will still process teh command and therefore, the hosts
resources will take a beating.

Basically, it looks like any user can severely drain
your systems resources - a kind of Denial of Service
attack. I was able to use up all remaining processor
time for two hours (would have gone on for much longer
only I got bored and kill it).

CONTACT: You can email me at [email protected] if you
want to discuss this problem further (or let me know
if it works on any other ftpd).

Ok,

Nix..that last message...a single connect ran the load up to
about 1.5 but stopped at that point.

Multiple connects running this command will increase the load
accordingly.

So I guess the Denial of Service is in the one of the
following forms:

1) Start up anonymous connects and run the ls command

ls../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../
*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../
*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*../*../*

increasing the load to more then the system can handle. Thus
crashing the system.

2) Attempt to crash the system with the "nlist" vulnerability
but simply occupy all of the available connections and
cause the system load to be extremely high.
(In the case that you are only offering a fewer FTP
connects then it would take to crash your system)

These connections never appear to time-out since
they are being processed.

On my system after a steep initial climb in load it
has evened out at 1.5 for each ftp connect running
the "nlist" vulnerability.

This could get nasty.

As messy as the glob code is, I think the solution is to put in some
checks for globerr != NULL -- it looks like the code currently goes happily
on with its recursive matching even after the glob list is full and Gcat()
puts an error message in globerr. (Actually, it would be better
implemented by having functions like Gcat() return success/failure instead
of void, if anyone feels like rewriting the whole thing.)

While we're on the topic, setting CPU time limits on processes like
/bin/ls executed by the daemon would be a good idea as well--"ls -lR" on a
large tree would do some pretty nasty stuff.

Hi.

I tried to configure wu-ftpd with OPIE(OTP) support, and I couldn't find
any patch for it.

This is quick hack, but it works fine.
You also need OPIE distribution (I tried with OPIE2.2).

If you can, please include next release.

Thank you.

If you use opie 2.22 or before, you may check opiestate.keyfile.

If I set my anonymous ftp limit too low in /etc/ftpaccess, inetd stalls
out after a while.. complaining that in.ftpd is looping (i.e., too many
anonymous users are trying to connect, and inetd decides to shut down the
port all together). I can increase the anonymous ftp limit and things run
fine, although bandwidth gets saturated.

Is there a way to limit the bandwidth on individual anonymous ftp
connections, or allocate a total bandwidth to the anonymous ftp account?
This would be a nice feature. In the interim, how can I hack inetd or
modify ftpd so the ftp port doesn't get shut down when under too much
stress?

my guestgroup access works properly
with the exception of not being able to

Since uploading/downloading/renaming/deleting
all work...this makes me believe it is a shell
problem. I have an /bin/ftponly shell that
echo's "don't touch". My permissions are set
properly according to the man pages in ftpd....

Is there something else I should be checking?
thanks.

Is your shell in the /etc/shells file?
If your are using a /./ notation in your passwd file, does the ~/bin/ls
exist? ~/dev/zero? ~/dev/tcp? If your libraries are loaded dynamically,
do an ldd ~/bin/ls and see if any libraries are missing.
Have you looked at your syslog? Are you getting anything when you type
ls? What happens? What OS?

I have been able to get the "guest" setup up and working
properly accept the delete command. The files are owned by
the the guest users as is the parrent directory. I have also looked
through the archives and found discussion of this same problem and
I have tried many permission combinations with no luck.

The error is ...
553 manf.codes: Permission denied. (Delete)

yet ftpaccess says yes for delete from guest and the permissions as far
as I can tell are correct.

I am sure there is a simple thing that I am missing. Thanks

Pink elephants with an attitude inspired [email protected] to tell garfield.mail.wu-ftpd:

: I am compiling under gcc 2.7.2 but I'm a sysad not a coder. Can anybody help me
: get round this ?

Having run into a similar thing when trying to compile an early version on
FreeBSD you may want to check your src/conf.h file for the following line:

#define realpath realpath_on_steroids /* hack to work around unistd.h */

which should be the last one. The config/config.fbs file has:

/* Freebsd libc already has a "realpath"; this hack bypasses it. */
#define realpath realpath_on_steroids

which config/config.ptx doesn't mention so my guess is that you need to use
that 'realpath_on_steroids' thing for ptx as well. Now, how to hack this
into the source.. I'm not a coder either :) but you could start by adding
that #define to config/config.ptx or /* */ the declaration of realpath
in ftpd.c (i.e. not declare it there and have stdlib.h take care of it)
Of course, this may be all wrong in which case Stan or Kent will jump
in and lart me for the luser that I am who should really be installing
a mailserver at the moment but is waiting for a 8Mb testfile to be
transferred over a UUCP connection anyway.

Hi all,
I have put wuftp on a solaris 2.5.1 machine. I thought I read that the
login banner/welcome message could be changed. Is this true??
I would like to mask the fact that we are using wuftp to all outside
users coming in to the machine.

this list has come to an end and I'm trying to determine now how to
unsubscribe from it. If someone could send me some info on the subject
I would appreciate it.

Thanks,

Subject: Guest user setup
X-Sun-Charset: US-ASCII
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

Hi,

I need to set up a temporary ftp user, who for several reasons cannot be
in the "real" group, but still needs access to our entire filesystem. I
tries setting him up in a special group "web", listing the web group as
a guestgroup in my ftpaccess file, then using the string "/./home/webguy"
in my password file. I thought this might fake out the code, chroot him
to /, then start him off in his home directory. When I ftp'd in as this
user I got the dreaded "Can't set guest privileges" message. So for now
he's just got "/" as his home directory, and everything is working, but
I'm still wondering if there was a better way to do this.

I'm running 2.4.2b13 with virtual server support.

Then he is a real user, not a guest user.

Why not just set his path to "/home/webguy"? After all, he's inherently
chrooted to /. :) This will chdir him to that directory.

For which you don't need "/./".

-0-FIXES IN THIS RELEASE-0-
------------------------------------------------------------------------------
Ticket 419 from Samuli Kaski <[email protected]> notes a problem in
the ftpd man page. This has to do with a description of the command line -o
option. This has been fixed in this release.
------------------------------------------------------------------------------
Ticket 430 from [email protected], 433 from Bill Pemberton
<[email protected]>, 436 and 437 from John Simmons
<[email protected]>, 449 from Ole Holm Nielsen <[email protected]>,
456 from Tim Evans <[email protected]>, and 459 from Peter
Newman <[email protected]> pointed out a typo in fnmatch.c. This is
now fixed. I also made changes to fnmatch.c to accomodate the lack of certain
flag definitions on systems that claim to be POSIX compliant. These flags are
not used by the current wu-ftpd server code.
------------------------------------------------------------------------------
Ticket 431 from Marc Baudoin <[email protected]> pointed out some
configuration file problems when compling wu-ftpd on NetBSD. These changes
are in this release.
------------------------------------------------------------------------------
Ticket 432 from John Marshall <[email protected]> has pointed out a problem
in ftpcmd.y concerning correctly recognizing the PASS command in a non-case
sensitive manner. This change has been installed in this release.
------------------------------------------------------------------------------
Ticket 443 from Mark Bergman <[email protected]> and 444 from
Chuck Yerkes <[email protected]> sent in a bug reports for skey. A fix is
included in this release. It has been conditionalized since FreeBSD supports
the old calling method.
------------------------------------------------------------------------------
Ticket 448 from Eilon Gishri <[email protected]> reported some changes
for AIX 4.1.X that would allow virutal hosting to work on AIX 4.1.X. These
changes are included in this release.
------------------------------------------------------------------------------
Ticket 454 from Jon Lewis <[email protected]> and 455 from Simon Kirby
<[email protected]> were forwarded from the mailing list to address a problem
with the new expired password support in beta-14.
------------------------------------------------------------------------------
Ticket 460 from Jay Vassos-Libove <[email protected]> pointed out that
there was a bug in the configuration file for BSD/OS, though he thought it
was in the pathnames.h file. The correct fix has been included in this release.
------------------------------------------------------------------------------
Ticket 463 from Koga Youichirou <[email protected]> and 468 from
Andrey A. Chernov <[email protected]> pointed out that there was a bug in the
configuration file for FreeBSD. The fix has been included in this release.
------------------------------------------------------------------------------
Ticket 467 from Koga Youichirou <[email protected]> pointed out that
the s/key challange in wu-ftpd did not conform to RFC 1760. This has been
fixed in this release.
------------------------------------------------------------------------------
Ticket 469 from Andrey A. Chernov <[email protected]> submitted some
revisions for FreeBSD support of wu-ftpd. These are included in this release.
------------------------------------------------------------------------------
Ticket 470 from [email protected] pointed out a problem in the "NLST" command
that could cause a system to eat up all memory and get sluggish. This could
be seen as a Denial of Service attack. I have changed the software to detect
this type of attack and not permit it.

Hi

I have 6000 users in my password file. they do not all connect
simultaneously. I have got the patch for big passwd file, so that
timeout errors do not occur.

Has anyone experienced problems with wuftpd dying if the password file
is too big. Will I need to ove to a commercial server like ncftpd.

Before I can persuade anyone to go down this line, I need evidence that
this problem will occur.

Thanks

Iqbal

Gentle People
Is there any known problems with WU-FTPD and port requests?
We are currently finding in an ISDN connection (don't know if it happens
in LAN environment) we are seeing intermittent port requests hanging.
Before "STOR" or "LIST" the client FTP asks for a data port. The FTP log
shows the port request. In our sniffer trace we see a transport
retransmission until the client ftp times out and resets the control
port and goes away. Some moments later the same user then logs back in
and works again. This is totally intermittent and no rhyme or reason as
to why it stops at any given port number. It happens for multiple users.
Any information would be appreciated.

I have 19000 users in my passwd file. Though I have not noticed any
problems caused by having so many users, I was not aware that there was
even a potential for a problem (other than memory constraints for
simultaneous connections). What is the big passwd file patch supposed to
fix (timeouts on what: connect, read, write?) and where do I get it?

Subject: AIX config problems
X-Sender: "Ben Newman" <[email protected]>
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

There were some problems that I encountered when trying to compile for AIX. My
understanding is that this has been fixed in the *newest* release, but I thought
it might be worthwhile to mention the fix I made.

fnmatch.c does not compile due to undeclared identifiers. The problem is a
conditional define in the preprocessor directives. It originally looked like
there was a typo in

#ifndef _POSIX_SOURCE
#ifndef FNM_LEADIND_DIR
#define FNM_LEADING_DIR 0x08

I changed FNM_LEADIND_DIR to FNM_LEADING_DIR (which only made sense to me, the
unitiated) but this got me nowhere. My system was still complaining about
FNM_LEADING_DIR and FNM_CASEFOLD bieng undefined. I tried defining them
unconditionally, and voila! I have this nagging feeling that it was too easy,
and it is going to bite me in the ass later, but hey:no problems so far...

As for installing wu-ftpd as a test daemon, I think it might be worthwhile to
have slightly better documentation per the building and installation. To those
of us who are unfamilar with Makefiles, it might be worthwhile to talk a little
about the changes that need to be made. Think about it: Who would install the
test ftpd in the same places as the real ftpd? You kind of have to jump through
some hoops to get what you want, and it can be a pain if you are going it alone.

Thanks for answering, but as I said, this guy cannot be in the real group.
The users in the real group have special authentication mechanisms that
this temporary person will not have access to, and access restrictions
that will not apply to him.

All I want is for him to:

1: Be in his own group for ftpd access purposes.
2: Have access to the entire filesystem.
3: Have a proper home directory and start out in it (for shell access also).

Authentication methods aside, from WU-FTPD's stand point he is a 'real'
user. Sounds like you need to work the source a bit to find out why /./
at the beginning of the string is failing and either fix it or hack it.

Why is it that when I have a guest group set up for a user and I link his
directory to a directory that is globally readable and executable, wu-ftpd
tells the user they can't switch to that directory because "too many
symbolic links encountered"? What can I do to reverse this and enable it
to travel via symbolic links. Thanx

Well, I don't think it's a case of that. I can use this link just fine
normally. It just symbolically links to a directory. It is a limit that
seems to be imposed only to guest users. I don't want to make the user a
real since I want the chroot to be the home directory.

I've had the WU ftpd installed for some time now and I just
realized that the logging doesn't show up like the old ftp used to; I
mean, Sun's Solaris ftpd adds lines to the wtmpx (which is read through
the "last" command).
Is this situation easily resolved? Are there plans to modify this
behavior (or lack of) in future versions of the program?

Works fine on Linux--though Linux uses "wtmp" rather than "wtmpx";
maybe this is a wu-ftpd/Solaris configuration problem?

It is working just find here. I'm running Solaris 2.5.1 and have not had
a problem. Is accounting turned on ? Does the /var/adm/wtmpx file exist ?
I don't remember doing anything special here...

In answer to your questions, I'm not sure what you mean by
"accounting turned on" (forgive me, there are things I don't know about
Solaris admin). And as for /var/adm/wtmpx, it exists, and last still
shows the log of people having logged into the machine regularly...just
not ftp (well, not when wu-ftp was installed, but it does for the few
times I ftp'd with the vendor provided ftpd).
I checked the source; there's no mention of wtmpx, but lots of
mention of wtmp (which is working, as far as I can tell; wtmp time stamp
changes when someone logs in or out through ftpd).
Something I omitted from my first message: OS: Solaris 2.5.1.
WU-FTP version: 2.4.

I waited because I thought someone else would answer this, but here goes ---

Eric Stewart <[email protected]> mentioned that logging into
/var/adm/wtmpx did not work for him under Solaris 2.X. He says:

> I checked the source; there's no mention of wtmpx, but lots of
> mention of wtmp (which is working, as far as I can tell; wtmp time stamp

He is running an old version of wu-ftpd. I remember in the days I was running
wu-ftpd 2.4 that Caspar Dik had a patch on ftp.fwi.uva.nl to unable handling
of wtmpx. The current version (wu-ftpd-2.4.2-beta-15, available from
ftp://ftp.academ.com/pub/wu-ftpd/private/wu-ftpd-2.4.2-beta-15.tar.Z) has
proper support for wtmpx builtin. It is working fine for me (Solaris 2.5).

Am I missing something here, or do you have to make sure that there is a '-L'
that appears in the inted.conf file to enable logging? My understanding was that
logging was disabled initally (default '-l') and you had to explicitly turn it
on.

You probably already did that: I just thought I would throw this at you to make
sure...

I'm running wu-ftp 2.4 on AIX 4.2.0 and I noticed that the passwords for
all users (anonymous and guest ids) are logged in syslog as clear text. I
remember somebody posed this question in the past and the reply was because
the daemon was started in debug mode. My daemon is not in debug mode and I
see the problem.

How do I fix this problem?

Thanks

Greetings,

I'm currently running wu-ftp 2.4<2> on Solaris 2.4 SPARC, and am trying to
make a directory structure accessible only to the local domain
(*.csuohio.edu). Can this be done to the anonymous account? (I'd like
anyone to be able to FTP in as anonymous, but have ftpd check the IP
address when they try to enter this other dir structure).

ie:

/ ----------- dir 1 (Accessible to all anonymous users)
----------- dir 2 (Only accessible to local domain)

Or, is the best way simply to make another account with this other
structure as the home directory, and use the ftphosts file to restrict the
access to my local domain?

Thank you,

Hi,

On a Sparc 5 running Solaris 2.5.1, I am trying to run the build to
create the ftpd. The cc (C compiler) is complaining about strunames,
typenames, modenames and filenames being undefined. As per the
instructions I replaced the support/ftp.h with the
/usr/include/arpa/ftp.h (of course renaming the orginal) reran it and it
has the same exact errors. Any other files I need to look at?

I sent this early this morning but our mail host was hosed up. Please
excuse the repeat.

Thanks,

You might want to investigate editing the makefiles and using gcc
instead of cc.

Hello...I'm trying to setup chroot FTP on BSDI 3.0. I've got it
working to the point of making the root directory in the correct place,
but what I can't do is run ls. I don't get anything back. executing
mkdir works though (after FTP I telnet back in and it's there). I've got
the shlib directory setup (along with all the others) and I've copied the
libc_s.2.0 library from /shlib and set it to 555. this is the library that
ls depends on right? thanks, Adam

Hi,

I have just done this on an e4000 running 2.5.1 and got the same problem,
followed the notes and it works fine. The only thing I spot wrong is that (at
least you say that) you replaced the wrong file. You need to replace
/usr/include/arpa/ftp.h with support/ftp.h rather than how you described it (the
other way round,

Just in case you did read INSTALL wrong,

Martin

PS Sorry about the company bit at the bottom.

Hang on a sec -- you shouldn't have to do anything like that to build the
current version on a Solaris 2.5.1 system. To check that, I just
downloaded it and ran

/build sol

on a 2.5.1 system, using Sun's C compiler, and it compiled without a
whimper.

I also tried

/build 'CC=gcc' sol

to use gcc 2.7.2.2 instead of Sun's C compiler, and again it compiled
without a peep.

I think that stuff about include files was for the old version of wu-ftpd,
which you don't want to be running (for lots of reasons).

In case you missed the recent announcement, the latest version is
available from

ftp://ftp.academ.com/pub/wu-ftpd/private/wu-ftpd-2.4.2-beta-15.tar.Z

Subject: Problem with wu-ftpd-2.4.2-beta-14 in Debian Linux

Today I tried installing wu-ftpd-2.4.2-beta-14 on my Debian Linux system.
The compile went fine, as did installation. The daemon itself is running
almost flawlessly.

My current problem (which I suspect is simple to fix) is that when a user
logs on, they arent being counted, so my maximum user limits arent being
enforced. /var/log/xferlog also isnt being written to.

nitehawk:~# ps ax | grep ftp
29759 ? S 0:00 ftpd: immortalis.nitehawkis.com: immortal: IDLE
nitehawk:~# ftpcount
Service class all - 0 users ( 10 maximum)
nitehawk:~# ftpwho
Service class all:
- 0 users ( 10 maximum)

The same thing goes for when an anonymous user is logged on. I modified
config.lnx to make sure everything in pathnames.h was pointed to the right
files, including utmp and wtmp, but ftpd still isn't functioning properly.

Any ideas? Thanks,

-%- Cade Cairns

I am in the process of installing wu-ftpd on our machine - a Solaris system. Is there a
way to restrict ftp access to a various directories. For example, a user's directory is
located at /usr/home/username

The user starts in the username directory by default, but can change directories to
anything else, including /etc . I only want the user to be able to see his or her own
directory and not be able to view anything else (i.e., a list of users or cgi scripts).
Any thoughts or suggestions?

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

Hello.
I have heard mention over the past couple days of a problem with the way
wu-ftpd uses the passwd file which causes problems when the passwd file
becomes very large. I have also been told that there is a patch to correct
this. My question is where can the patches be found? I looked at the
resource center, but only found a couple recent patches in the developers
corner. I would like to be able to see what other problems/patches exist
that I did not know about as well.

Thanks.

I can't get xferlog to record any transfers. I have added the following line to
the inetd.conf file:

ftptest stream tcp nowait root /users/benneman/ftp/ftpd ftpd -L

A ckconfig confirms that I have the xferlog file in the right place.

My ftpaccess file has the following lines:

log commands real,anonymous,guest
log transfers real,anonymous,guest inbound,outbound

I have tried everything I could think of. Any suggestions?

The external ls is not operational. The guest howto, the FAQ, and the

Subject: Server Modifications for alias expansion

X-Mailer: Microsoft Exchange Server Internet Mail Connector Version 4.0.837.3

Hello,

Been watching the list for a while, but not much participation.

I have a question regarding alias expansions in wu-2.4(11)

I have aliases set up for a number of directories, which work well,
except as used within a web-browser context. Since the browser never
performs a 'PWD' after a successfull 'CWD' it doesn't see that it has
been the victim of an alias expansion.

Now there is a positive and a negative associated with this. The
positive aspect is that aliases can be used to 'hide' the actual
structure of the file system. This is good for security reasons. The
negative aspect is that any attempt to retrieve the file results in a
'file not found' error.

This error is only incorrect in that the server is not parsing for
aliases before attempting to stat() the file. Unfortunately, my C
programming has gone downhill in the last few years from non-use, and I
don't think I'm up to the job of trying to hack ftpd.c into performing
this task. It looks like the code is available ( cwd() performs this
check ) to do the job.

I'm not sure what the ramifications are of this kind of a patch, but it
seems like adding support for aliases within browsers would be a welcome
thing.

I might try to do this.. I've already fixed the cwd() code to
"correctly" strip off trailing path separator characters, i.e. '/',
from the pathname before checking for aliases.. This helps out a lot for
browser capabilities, and hasn't seemed to hamper functionality.

Any comments?

Leif Sawyer

I'm running wu-ftpd beta 13 and it doesn't seem to allow DELETES or OVERWRITES
regardless of how I configure it.

The ftpaccess file says the default is "yes" for everything. I've tried just
about every combination of possible configuration options and notice absolutely
NO CHANGE in the behaviour of the FTP daemon. I checked the top-level config.c
file in the distribution I got, but it looks fine as well. Have I just
discovered a bug or am I missing something really obvious!?!?

Please help. Replies by e-mail as I can't afford the added bandwidth of the
list.

Thanks!

Hi,

I have modified 'adduser' to setup guestaccounts for me (making it
'addguest'), but in a very ugly way (i.e. the script, not the accounts;-).
Has anyone made a nicer script? Maybe with password-generation included? I
have seen a perlscript in the archives, are there other ways? The guest
accounts are for homepages, and it would be nice to have one script to do
it all for you. Actually, I'd like to add the email-addres of the user as
an option after <username> and let the script send the passwd rightaway.
About the security touches in the guest-accounts howto, they seem
to be appropriate/functional in only a few cases, i.e. when a user can't

I think the idea of making .forward, .rhosts, etc. is for daemons that
don't run chrooted, such as sendmail. However, this raises an interesting
point that I have never considered. When a chdir() section is added,
something like "/home/web/mort/./public_html", where do various daemons
think ~ is? mort or public_html? In a sense this is moot for a well
configured ftpd, because files with a leading '.' can't be uploaded.

I'm running it under Solaris 2.5.1 (SPARC). I have only built this version
at the moment, but I've downloaded beta-15 and will test it as soon as possible.
Unfortunately, due to Real World constraints (the server is in production and
I don't have easy access to another solaris box) it's problematic to test other
versions. It can be done, it's just painful. :-)

I will probably try an earlier version (2.4?) as well just to see what happens.

I didn't notice anything in the notes for beta-14 or beta-15 that suggested
there was such a problem or that it had been fixed.

Thanks,

Yes, that's exactly what I have been trying to figure out, in fact, I have
tried the exact same entry with public_html;-) A cd ~ still will say:
/home/web/mort: No such file or directory.
You are right, it should not be a point.

What about uploading a file rhosts and then renameing it .rhosts?

(my 2 cents)

Good question. It's been a while so I'd forgotten how I configured it. The
answer is yes, I *am* using the -a option. And I know it's reading the
ftpaccess file, because if I *move* it everything breaks.

Oh yeah, FYI, I'm doing my tests with "ftp localhost" and am not going through
a firewall or any kind of proxy.

Logging in as a regular user and trying to delete any file out of my home dir
gives me a "553 <file>: Permission denied. (Delete)"

Normal file perms on those files are fine. I can manipulate them however I
want from the shell.

The way I read the ftpaccess(5) man page is that I could have NOTHING specified
for "delete", "overwrite", etc. and the default is yes. I've tried this and
I still can't delete. I've also commented out all of the default lines and
then just left one line like the following:

delete yes real

The way I read the man page this should explicitly give me write permissions,
correct? It doesn't.

Very frustrated, but grateful for all of the responses so far...

Subject: Patch for window size
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

Hi.

I'm not on the list so please copy me on replies. I wrote
a patch to fix slow throughput we were getting from dialup PPP
customers grabbing files of our FTP server. I've included them
below. It's fairly straightforward.

You want to add -DUSE_BIG_WIN to your Makefile, and then
add the following flag to your /etc/inetd.conf after installation:
"-w 32768" (or more). Otherwise, you will use the 8760 byte window
that Solaris has, or something comparable for your OS.

X-Sun-Charset: US-ASCII
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

Hello,

Because of signal handling bugs in various ftpd implementations as
reported in CERT notice CA-97.16 * I installed wu-ftpd-2.4.2-beta-13
but didn't realize at the time that ftp conversions weren't working.
We are using this on a Sparc running Solaris 2.5.1. I just this week
tried updating to beta-15 but still no ftp conversions. I then
installed the latest non-beta namely wu-ftpd-2.4 and ftp conversions
are working again. However, "this version of 2.4" seems to be slightly
different than the 2.4 I had fetched initially. (diff on the source
reveals very few but definite code differences.) Is the latest 2.4
safe as far as the CERT CA-97.16 is concerned? (And why didn't the
version number get incremented?)

Any guesses as to why ftp conversions do not work with the beta
releases? I put everything in the same places for both non-beta and
beta and ckconfig claims to be completely happy. It seems like it must
be something really simple but it is escaping me.

* The CERT notice is at ftp://info.cert.org/pub/cert_advisories/CA-97.16.ftpd

Thanks,

Gerald Justice

Hello,

I have trouble to setup the wuftpd in SCO

I have the binaries of WUFTPD 2.1

When I log with my account test

the chroot command seems to be not executed, when
I do the command pwd

Instead of having the / I have my path /home/test

And I've copied the library under /home/test/lib and /home/test/usr/lib

I've created the device under /home/test/dev

In my password file I have /home/test/./ like home directory

In my ftpaccess file I have
--------------
private yes
class all real,guest *
guestgroup all

.....
---------------

when I'm doing the chroot manually It's working.

Does somebody have a idear ??

Thanks,

Why don't you use ftpd -i ?

Upgrading to BETA-15 did the trick. I changed out the binaries and voila,
everything magically started working. Just an FYI.

I have just got 2.4.2 working (to a degree) on dynix/ptx 4.4. It is now at the
point where it asks for a user name. If I enter any username which is in the
password file I get 530 (User x access denied...). If I enter an invalid
username it asks for a password then gives me the same message.

The only thing which I think can be wrong is the class definition in ftpaccess,
but any attempt (including the example file) gives the same results.

I have proved it is using ftpaccess with a banner command and tried using -A
which doesn't use ftpaccess but still gives 530 for any valid username.

Anyone any suggestions ?

Martin

Hi all,
I am getting the following error when I ftp to a beta14 install on
2.5.1 solaris:

ftpd[467]: wtmp /usr/adm/wtmp No such file or directory

I have set the path in pathnames.h to be /var/adm/wtmp.

Why do I get this error on the console?

Are you sure that got into the binary? Try running
'strings /path/to/your/binary | grep wtmp'

A quick workaround would be to make a symlink from /usr/adm/wtmp to
/var/adm/wtmp.

Hi all,
Thanks for the head slap Jim. I found the "error".
I rechecked my work and found that the inetd.conf was wrong; the path
was firing the wrong program. I don't know what I was thinking.

I have placed the nodirs variable in the ftpaccess file, but it doesn't
work. My users can successfully create directories. How do I make this
work? This is the result of a "grep nodirs ftpaccess":

upload /var/ftp * no nodirs
upload /var/ftp /incoming yes root daemon 0600 nodirs
upload /var/ftp /bin no nodirs
upload /var/ftp /etc no nodirs

I also killed and restarted inetd, and the running ftpd.

Do you have the -a option in your /etc/inetd.conf file? Here's ours
from an SCO system

ftp stream tcp nowait root /usr/local/etc/tcpd /usr/local/etc/ftpd -alL -u022

: Logging in as a regular user and trying to delete any file out of my home dir
: gives me a "553 <file>: Permission denied. (Delete)"

: delete yes real

Any chance there are controlcharacters in there by accident? Does it work
for the other stuff like overwrite? The files aren't mounted/linked from
somewhere else? Is the entry whitespace or tab-separated? The above one
has 2 tabs it seems?

Me, I have:
delete no guest,anonymous
(tab-separated) and it works just fine for b13.

Pink elephants with an attitude inspired Anne Baretta <[email protected]> to tell garfield.mail.wu-ftpd:
: I have modified 'adduser' to setup guestaccounts for me (making it
: 'addguest'), but in a very ugly way (i.e. the script, not the accounts;-).
: Has anyone made a nicer script? Maybe with password-generation included? I
: have seen a perlscript in the archives, are there other ways? The guest
I'm not sure for which OS this is, but modifying adduser to use other
defaults shouldn't be too hard? The one for FreeBSD already is a Perl script
I think and I've modified it to add popboxes easily. Basically stripping out
the stuff I don't need and provide some defaults. The main tricky bit is the
locking stuff and making sure you don't mess up stuff depending on a certain
format of the password file (under FreeBSD it seems possible to create
multiple accounts with the same username under certain conditions. This will
show up in security checks but not in the standard rebuilds of the password
database).

: since it's /, the root dir? (if you do a cd ~ you get '550 /home/web/mort:
: No such file or directory'). Please let me know if any of this makes any

This is something I noted earlier (Kent Landfield and myself considered it a
bug) and submitted to Stan. He is considering it for 2.5.

hi adm:
I am tried to setup the wu_ftpd2.4 program.
I want to setup a ftp user.And let the ftp user's home directory
be a normal user's directory.I have let the ftp user use a different
group.and let the shell be the rsh.
Before I install the wu_ftpd program,the ftp user can't go anywhere.
They only can be in the directory by the rsh shell.
But if the user use the window program like ws_ftp in the windows base.
They can go to any directory of my unix system.So I tried to study
the wu_ftpd program.I want to know the wu_ftpd program can limit the
ftp user to go anywhere or not.And how can I do it?
I will be very appreciated of Ur help.
I hope U can know what I types,'cause I am not good at english.
thanks.

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 see the same problem on AIX. Actually anonymous and guest users are able
to create directories. I have the '-alL' in inetd.conf as well. I don't
even have the upload lines for my guest directories, yet all my guest users
are able to upload, create directories. Obviously because the permissions
on the directories allow them to. But I thought the ftpaccess file is
supposed to restrict what users can do even though the permissions on the
directories/files may be the opposite. This is something I have never
quite understood with wu-ftp. Can someone enlighten me please?

Thanks, Thuy

Hi,

I've just finished my install on Solaris 2.5. I am
able to establish a connection to the ftp server
from another system but when I attempt
to receive any data from the connection I get the
following error:

ftp> ls -al
200 PORT command successful.
425 Can't create data socket (0.0.0.0,20): Bad file number.

Any help will be much appreciated!

thank you,

The username is certainely owned by a guestgroup, and
the original path on the remote machine is relative
to the root directory of this guest group.
-> check your /etc/group file and be shure
that the user is not owned by the group 'guestgroup'
in the ftpaccess conf. file

We have installed wu-ftpd; all aspects working fine as long as we use an
ascii-based ftp. When we try GUI-based FTP such as Hummingbird Exceed FTP
or CuteFTP, the client can't see any files or subdirectories under the
user's chroot-ed home. If the user cd's up one level (to their perceived
"root"), they can no longer see even their own home directory. It's not an
ls problem, either; we've put 'ls' into ~/bin - even put it in each user's
home directory, just on a hunch. Exceed's built-in ascii mode (invoked
from the GUI) can see the files just fine. I'm in correspondence with
Hummingbird and CuteFTP, but was also wondering if anyone else out there
had run into this. Thanks.

Actually we ran in to this as well. I reran the anonymous setup
program and it fixed it. Exactly what was wrong I never figured out.

>From the line mode FTP program do 'ls -CF'; if you don't see any results,
the external ls is not working. For pointers, see the guest howto, the
FAQ and the list archives.

wuftpd has a simple 'ls' (with no options) built in; command line clients
will typically type just 'ls', so the built in function is used. Windows
clients usually issue ls with options, so the external ls is called. If
that does not work, your external ls is broken.

Hi !
Did anybody ever successfully build wu-ftpd on an NCR 3525 Host running
Unix SVR4.
I am having lots of problems getting a clean compilation.
To begin with, Unix SVR4 is not listed in any of the build options, so I
tried osf plus a couple of others (hpx, dec etc.). None of them seems to
work.
I think the 'c' libraries for NCR Unix SVR4 are not compatible with the 'c'
source codes in wu-ftpd. Here are just some of the errors and warnings I
get

w "ftpd.c",L1077/C21(#553): name
| Conversion of type `char *' to type `unsigned char *' is not
ANSI-compliant.

E "glob.c",L119/C15(#237): NCARGS: Identifier is undeclared.

E "ftpcount.c",L258/C18(#237): LOCK_UN: Identifier is undeclared.

I have exactly the same problem with Reflections FTP client. I have a call being
reffered to the developers now. Please mail me if your people have a solution
and I'll do the same.

I have a problem using beta15 on a Pyramid DC/OSx machine. This is
the initial port so I may have a setting wrong.

I can do an "ls -l" and the directory looks right. It also looks
right using "dir". Using just "ls", the first two characters are dropped
from each line. Any idea what is up?

To mbrennen and the others who replied:

Right, you were. Had to copy /bin/ls to the ~/ftp/bin and the terminfo
file to the ~/lib, and both GUI FTP's (Hummingbird Exceed and CuteFTP) are
working just fine. Also right: it's all there in the FAQ and the
guest-howto, both of which I had read several times, without understanding.
Looks like (in my case, at least) it took some degree of frustration,
coupled with some focused assistance, to drive the point home.

Many thanks to all of you who replied.

Hello,

We are looking for a way to solv the following:

- When a user uploads a .tar.Z file, it should be uncompressed and
untared in the upload directory which will create i directory-
structure there.

- When a user requests to download <directory>.tar.Z, the directory
should be tared, compressed and deliveried.

We can see in the manpages that it is possible, but don't think it's
clearly descibed how to actually do.

Anyone who can help us?

Regards,
Mattias Niklasson

Very dangerous:

mkdir tmp tmp/foo tmp/bin tmp/bin/ftp-exec
cp -p /bin/sh tmp/bin/ftp-exec
cd tmp/foo
tar cvf - ../bin | compress > foo.tar.Z
ftp your.server
[...]
ftp> put foo.tar.Z
ftp> site exec sh -c whatever

I'm sure there are plenty more interesting things you can do with this too,
but I'm too lazy to think them up right now.

>- When a user requests to download <directory>.tar.Z, the directory

Put something like this in /etc/ftpconversions (or wherever the
wu-ftpd files are on your system):

: : :.tar.Z:/bin/tar cZf - %s:T_REG|T_DIR:O_COMPRESS:O_TAR:TAR+GZIP

Note that (at least for b13) you need at least one space in each field or
wu-ftpd will crash and burn. Then add the following directives to your
ftpaccess file if they're not there already:

compress yes <classname> [classname...]
tar yes <classname> [classname...]

where the <classname>s are as defined in your "class" directives.

-----BEGIN PGP SIGNED MESSAGE-----

I just installed wu-ftpd 2.4 on a Dec Alpha, OSF1 v4.0, using
Digitals cc.
It works fine, except for 1 thing: When an anonymous user submits
a dir command (or ls -la or similars) she gets an empty list returned:

Remote system type is UNIX.
Using binary mode to transfer files.

For a real user the dir command works fine. I suppose there is
some configuration set to deny anonymous long listings, but I
cannot figure out which one, since this happens even for the most
simple possible ftpaccess file. The file permissions are as
recommended, that is r-xr-xr-x for directories, --x--x--x for
progs under /bin and even rwxr-xr-x for incoming.

I'm looking for any hints.

X-Mailer: ELM [version 2.4ME+ PL31 (25)]

Hi !

My basic problem:
-----------------
How to make the contents of a mounted CDROM accessible in a ftp-server?
The mountpoint of the CDROM is outside of the ftp-tree. Therefore
a link from the CD-mountpoint into the ftp-dir will not do the job.

I am using HPUX 9 ( with HP-ftpd; not wu_ftpd ).
The CDROMs are written with xcdroat0.96 on a Linux-box and mounted
via amd to the HP-boxes.
I am looking for a solution which allows me to use the same CDROM on
different platforms as/inside a ftp-server.

My Idea:
--------
Put the whole ftp-tree on the CDROM
/CD_mount_point/fist_dir_on_CD/<ftptree>

in /etc/passwd it would specify
/CD_mount/point/fist_dir_on_CD
as 'homedirectory' of the ftp-tree
( If another CDROM is in the CD-drive ftpd will not find its
'homedirectory' and refuse the access )

But: In this case also the binaries needed by ftpd (ls , ... )
would be on the CDROM. So I am fixed to one operating system.

Questions:
-----------
1) Would my idea work at all ?

2) Is there a possibility to specify different pathes for the
binaries needed by ftpd in the ftpd sources or even on the
ftpd commandline ?

My Idea is to burn for each operating system ( HPUX, LINUX, AIX,... )
a separate bin-directory on the CDROM and specify the path for
the binaries on the commandline of ftpd.
So I would be able to run this CDROM-ftpserver on different
platforms.

3) Are the other/simple possibilities to solve my basic problem
which work also without wu-ftpd ( HPUX-ftpd ) ?

All hints welcome

yours Tobias

I have the same problem with Solaris 2.5 on a Sun Sparc 10.
dir and ls -l are fine, but ls cuts off the first two characters of
the filename! This causes problems using an mget, since the list of
files to retrieve is drawn from the ls command.

Let me know if you find a solution--

Subject: initfile (e.g. .ftprc) for wu-ftpd
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

Some of our non-Unix users complain that uploading files to a wu-ftpd
server gives them files with permissions they don't like. While it is
possible to either start the server with "-u 002" or to issue a "SITE
UMASK 002" I think neither is an ideal solution.

So I thought a bit about it and have come up with the following idea:

wu-ftpd could use a file where each regular (not anonymous) user
could customize the server's environment, i.e. a .ftprc where one
could set options like umask=002 or default_directory=~/uploads.

Before I go on and implement such a feature I would like to get some
feedback from other users of wu-ftpd. So if you think such a feature
might be useful or if you think such a feature might be useless or
even dangerous, let me know.

Cheers, JC

The classic symptoms of comp.unix.solaris FAQ item 6.19:

Why doesn't readdir work? It chops the first two characters
of all filenames.

See http://www.wins.uva.nl/pub/comp/solaris/solaris2.faq for the answer.

`man ftpaccess`

Look for the upload directive.

Yes, I know about ftpaccess and use the upload directive regularly but
I don't see how that would solve the problem. While ftpacess is fine
for anonymous access or directories which I set up on a global scale,
it is cumbersome to maintain for some dozen users who want to change
directives every so often.

Just look at the following (real) problem: we have users who maintain
a web server and some files in the same web directory belong to group
A while others belong to group B and some more files should not be
group writable at all. Yes, we have subdirectories and no, we can't
put each group easily into their own subdirectory.

I could of course ask them to send me their custom upload directives
and merge those into our ftpaccess, but if we had a per user .ftprc
each group could set their options for umask and group for themselves
and could even download a different .ftprc without my intervention.

BTW: using the upload directive's format for .ftprc might be a good
idea though.

Depending on the FTP client you use, the problem may be on the client
side. Most UNIX ftp programs will attempt to store the 3d34 file in
/pub/design/tmp/3d34 on the local system when retreiving the file, for
example. If there is no /pub/design/tmp directory on the local system,
it can fail with "permission denied" - but the permission that is denied
is for storage on the local system, not retrieval from the remote
system.

Usually "get /pub/design/tmp/3d34 3d34" will work, though, to store the
file in the current local directory.

Since wu-ftpd allows the umask to be set on the fly, this particular problem
seems to me to be a client-side issue. Can these users find a client which
will let them issue the umask command - preferably by using some sort of
local configuration file which is read by the client at startup ?

I would prefer this to modifying wu-ftpd, for the following reason :
if the standard FTP protocol already provides a way for setting the umask, we
should be encouraging clients to make use of it, instead of adding a
non-standard alternative.

Cheers, Bob

Thanks, that works (and I dimly remember having done so on a
sparc a couple of yesars ago).
I solved the Problem by recompiling GNU fileutils and linking
statically.
Since only ls is needed this time I may save the diskspace for
the whole libs.

Thanks.

Hey folks. I have a problem: I've installed wu-ftpd and set up a
ftpaccess file with a bunch of guestgroup accounts... When I ftp
from one machine (a digital unix box), I can ls and see the files,
but when I ftp from irix or linux boxes, I can't.

Anybody have a clue?

Hi all,
When I login as the guest group and try to cd ../ it works fine. If I
cd / it takes me to the system root. This is unacceptable.
I tried setting the CDPATH in ftpaccess to the ftp root and that did not
work.

Look at the guest howto, FAQ and list archives in that order.

This is the location for the latest wu-ftpd. You can't see the

Is the user who logs in, in the guestgroup and (for some versions of wu-ftpd)
is that their login group?

Is their home directory (in /etc/passwd) the form /home/ftp/users/./dir ?

If you don't want them to be able to telnet in (which it sounds like you
don't), did you give them a non-login shell, and put it in /etc/shells?

Hi there everyone.

Sorry to be such a pain, but I have an error message when
trying to execute a command. Yes, I know the explanation
is somewhere - I have even seen it myself! - but I just dont
seem to be able to find it again. I am running wu-ftpd on a
Sun Netra, Solaris 2.5.

Anyone please point me in the right direction, thanks.

Follow the Solaris in.ftpd(1M) man page, it gives details on
setting up chrooted anonymous ftp.

Generally speaking, you can't build statically linked binaries under
Solaris (you'll need libs in /lib in your chrooted area for /bin/ls),
and you need /dev and some device entries in your chrooted area.

I just got singed in private email for having sent the same unhelpful
response about guest howto, FAQ and list archives for the nth time.

The guest howto and FAQ were written precisely because of the frequency of
certain questions. I wrote the guest howto over two years ago precisely
because guests were the single most common question on the list, and I got
tired of recreating the same responses over and over. It is detailed and
takes time to answer.

The guest howto, FAQ and docs included in the distribution are the
essential starting points for anyone having trouble. Anyone on this list
for some time can attest that the vast majority of questions are
answerable with the guest howto and FAQ. The mailing list archives are
another excellent resource for filling in the holes. If people are not
willing/able to go over the established docs first, I have absolutely
nothing to say.

If these resources are not well noted on the mailing list subscription,
they should be. I've not subscribed in some time to see what is sent out.

If you find something in your situation that is not covered in the
commonly available docs, please work with the document author and get your
new info added in so others can benefit from it.

I was accused of adding little more than noise to the list. I don't
pretend that the same info hasn't gone out over and over and over -- in
response to the same questions being asked over and over and over.

If anyone has a good solution to answering the same questions without
sending the same information, do it. If anyone wants to recreate the same
answers over and over again, do it.

I've sent my last.

Screw them... Every time a question on the faq or guest howto is asked,
your response should be sent out. It's not anyone's responsibility to
cut and paste out of man pages, faqs, or howtos just because the user
is to lazy to do it themselves. A pointer to those resources is fine.

Brian is absolutely correct. Michael, do not stop responding to people's
questions. People need answers and many are not permanent members of the
list but people in need. You and Koos and many others have been trying to
help people get started. Your reference resource pointer is valuable as it
directs people to search the right places. Those that feel you are adding
traffic to the list are dead wrong. You are reducing the unnecessary
repeated threads and oldtimer versus newbie flame-wars. It has helped
keep the list focused as one that assists new users to the right places
and allows for real discussions about ongoing improvements to WU-FTPD.

Keep it up!

This hacks me off. Not at Mike, but at the sender. Seems there's always
somebody who wants to turn up the heat under the Goose that Lays the Golden
Eggs. I saw the same thing happen at the Cincinnati Reds Spring Traiing
camp in Plant City, FL, a couple of years back. Some of the players were
signing autographs after the practice, and this one guy who was either too
impatient or too arrogant to wait started banging on one of the players'
cars. The player was out of there, and the fans were SOL.
I'm a relative newbie at this wu-ftpd thing myself, and there have been
times when I looked over the FAQ and the guest howto AND the archives and
thought the answers weren't there. But, when Mike's pointed me to the FAQ
or the guest howto, he's been right. 'Nuff said.

But that is not noise. If you know the answer is in one of these sources,
you are providing a service to both the person you are responding to, and to
other new folks on the list, by pointing out the existence of these docs
publicly.

This is much more preferable than clogging the list with detailed answers
to the same old common questions again and again. So you're also doing all
the old hands a service at the same time, by helping to keep the noise
level down.

I'm sure many of us understand and appreciate this. Until the list server
is able to append this information to the end of every posting as a short
footer, this is the best way of getting it out. So thanks, and please keep
up the good work !

Cheers, Bob

PS It would be interesting to know what are the most frequently asked
questions these days. I bet the directory listing problems (missing
libraries and/or binaries) are right up there with the guestgroup items...
(Mind you, there is some overlap between the two.)

Is this something people would want to see ? On the end of every message
or once every couple day ? We can change the list parameters to make it
so. My guess is that people would rather Mike continue being helpful then
adding a footer to each message. If I'm wrong, let me know.

Alright, I guess I'll step forward and fess up. I was the one who
"singed" Michael, although that was not my intention. (I stated
repeatedly that I was not trying to offend him, I had read the
documentation; his message was no help to me.)

That was an utterly stupid thing for me to do. I have already
apologized. I do realize that sometimes lists like this get posted with
a million million questions about basically the same thing, and I can
understand that it gets old repeating the same things. That's what
FAQs are for. But doesn't it say something when people ask the
same questions again and again? Not every person who posts a question
is illiterate, you know. Perhaps the method is difficult, perhaps the
documentation is poor. Perhaps it's something the community should
address.

Ack. Sorry, anyway, I apologize. I should not have called Michael's
pointer to the faq's "noise." I was fustrated and took it out on him.
A totally horrible thing for me to do. Flame me if you wish.

I don't care to flame you, and I certainly hope the rest of the list will
refrain. It won't do any good AT ALL.

As I wrote you privately, if you find holes in the established methods,
work with the document authors to get the fixes in place.

This is not Unix school, and yer mutha don't work here. If it is hard, go
slow and work through it. Can't tell you how many times I've done that in
the last three years, and I've got 21+ years in software kernel and system
development. New concepts, new details.

For those that want the answer spelled out for them: F - A - Q

I thought that the reason we couldn't do the footer was because of the list
server software that we are using. I didn't think that ListProcessor(tm) by
CREN supported automatic appending of footers to messages, not even in version
8.0, but I could be wrong. Also, I thought that we were going to put the
guest howto and FAQ information in the welcome message that new subscribers
get and ask them to read these before posting to the list. Did we ever do
that?

I second and third the support of Michael pointing to the various
docs when folks can't find the answers. It folks like Michael and
Koos et al. that keep this list helpful.

I also applaud Chris for stepping forward and finally I vote for the
footer also.

It is in the welcome message but I'll have to check about appending a footer.
I thought it was possible in 8.0 (although I've never done it). I could be
wrong.

If you're talking about a footer like "Read the FAQ, Read the guest-howto.
Read them again"
I'll vote FOR. Anything longer, and we're REALLY talking about netnoise,
and I vote AGAINST.

And pointers to the FAQs on the subscription greeting e-mail. I just checked
my copy and, unless it's changed in the past few weeks, the greeting
currently only has the URLs for three web sites .. the FAQs themselves should
be added to the end with them.

Is this something people would want to see ? On the end of every message
or once every couple day ? We can change the list parameters to make it
so. My guess is that people would rather Mike continue being helpful then
adding a footer to each message. If I'm wrong, let me know.

No, a one line footer might be of little help. Just like the one line
which caused that thread (Michael, I know you intend to be helpful and
I really appreciate that) but what actual help does it give?

Look at the guest howto, FAQ and list archives in that order.

I can understand that someone gets frustrated by that response.
Where's the guest howto located? Where's the FAQ? Where are the list
archives? They are not distributed with the source (at least the last
time *I* looked for it they weren't) and I guess most people which are
(more or less desparately) looking for help just don't know where to
look for them either, so how helpful is such a line actually?

I'd rather have someone posting a short paragraph instead, maybe
something like:

Look at the guest howto, FAQ and list archives in that order. You
find the FAQ at http://www.cetis.hvu.nl/~koos/wu-ftpd-faq.html and
it will direct you to the other documents too.

If the URL of the FAQ would fit into a one-line footer that would be
fine. If not, I guess the on-line footer would be of little help. So
maybe

>>> The FAQ is at http://www.cetis.hvu.nl/~koos/wu-ftpd-faq.html <<<

would be a footer for all of us?

Cheers,

Admittedly, probably nothing. Sticking things in front of people's noses
hasn't worked yet; no reason to think it will in the future.

I'm not trying to naysay everything; given the history, I just don't know
what will work.

If I put in a oneliner like above, I *ALWAYS* send that great blob of a
footer that describes how to get to every piece of it.

Given history so far, this will probably cause little improvement. If the
big footer I send doesn't do it, how effective will this be?

Can't hurt, might help in a few cases.

Given history so far, this will probably cause little improvement. If the
big footer I send doesn't do it, how effective will this be?

We never can know how effective it is, because we don't see the
questions which don't get asked. Those who look at the documents you
mention and find their answers don't show up in your accounting. Like
the traffic lights: you always remember the red ones, not the green
ones...

Pink elephants with an attitude inspired Kent Landfield <[email protected]> to tell garfield.mail.wu-ftpd:
: # I thought that the reason we couldn't do the footer was because of the list
: # server software that we are using. I didn't think that ListProcessor(tm) by
: # CREN supported automatic appending of footers to messages, not even in version
: # 8.0, but I could be wrong. Also, I thought that we were going to put the
: # guest howto and FAQ information in the welcome message that new subscribers
: # get and ask them to read these before posting to the list. Did we ever do
: # that?

: It is in the welcome message but I'll have to check about appending a footer.
: I thought it was possible in 8.0 (although I've never done it). I could be
: wrong.

Basically, from experience with other mailinglists (like e.g. the redhat
lists where they add a footer and some others that send useful stuff on
subscription) they both won't stop FAQs, but please don't send a reminder
every couple of days.. those most in need of it either just subscribed or
are mailing without being subscribed AFAIK. On subscription they should
receive a short mail with the relevant unsub info and pointers to the most
used faqs/mailarchive/etc. Heck, I'll even write that if nobody else does..
It might include something along the lines of 'FAQs may not be answered..
check the FAQ lists first'... but there are probably a couple of compulsive
answering people here like me that can't stand a mail without a Re: :)
And nuking the first mail someone sends would probably also be useful, but
that's not an option most of us will like I guess :)

Seconded. This is the sort of thing that gets added to messages in a
couple of other lists I read and it doesn't bother me.

OK. Before this goes too much further (I've already received 4 votes
for the footer...) Let's make it official... ;) Let's vote and just
see what people want.

I don't want to clutter up your mailboxes so please send me private mail
and I will post a summary with the votes in a single message in a day or
so.

Here is what we are voting on.

YES - NO Do you want to see the type of information Mike has been posting
added as a footer to each message going to the list ?

I wrote this originally simply for my own use, but I just saw it on your
todo list, so I'm offering it up. It's currently at version 1.02 and
seems to be -must- faster and -much- less buggy than the perl version
(sometimes the perl version simply wouldn't report correct numbers).
Anyways, it supports everything the perl version did, and you're welcome
to contact me for additions, I'll try my best :)

You can fetch it at ftp://fuck.off.net/pub/xferstats-1.02.tar.gz if this
uuencode doesn't suit you.

Subject: Variable user limits based on load
MIME-Version: 1.0
Content-Type: TEXT/PLAIN; charset=US-ASCII
X-Sender: [email protected]
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

The way it works is really simple: lines of the format "load-limit <class>
<minimum load> <limit> <message>" are inserted. When the load reaches
that minimum, the limit for that class is set. In the case of multiple
limit statements, the limit is set by the highest load. Example:

limit remote 15 any /etc/msgs/msg.toomany
load-limit remote 5 10 /etc/msgs/msg.toomany
load-limit remote 10.4321 5 /etc/msgs/msg.toomany
load-limit remote 15 1 /etc/msgs/msg.toomany
load-limit remote 30 0 /etc/msgs/msg.toomany

If the load is below 5, the limit is 15 users.
If the load is between 5 and 10.4321, the limit is 10 users.
If the load is between 10.4321 and 15, the limit is 5 users.
If the load is between 15 and 30, the limit is 1 user.
If the load is 30 or over, the limit is 0 users.

Under any situation, the lowest limit always takes the top priority.
Example:

limit remote 15 any /etc/msgs/msg.toomany
load-limit remote 5 20 /etc/msgs/msg.toomany

No matter what the load is, the limit will be 15 users.

Any questions? That seems to be a pretty thorough explanation, probably
too detailed (most of you are rolling your eyes at the multiple lines of
examples :)

I've written the patch for Linux, but I don't know how to calculate the
system load on other OSes and I lack machines to test the code on anyways.
Anyone willing to send me some code that snags the load average on some
other wu-ftpd-supported architecture and I'll add it into my patch?

Phil

Hi all,

It has been a while since I have been using wu-ftpd and the last version I
used was wu-ftpd-2.4.2-beta-13 I went to
ftp://ftp.academ.com/pub/wu-ftpd/private/
but didn't see anything in there. Can someone tell me what the latest vers
is and how can I get a tar file I have lost my HD and need to locate a new
file.

Now that I think about it, for load limits, should it just be another
option tacked onto the "limit" command, so that you can have different
system load limits at different times of day? Or should I add the time of
day option to the load-limit instead? Or does no one care? :)

In addition, I just added time limits to wu-ftpd sessions and I thought
you should know so no one else spends their time doing it :) It has a
line of the format "time-limit <class> <n> [allow]", where n is the time
limit in seconds. If the word "allow" is there, it will allow
already-started transfers to continue over the time limit and cut them off
once their transfer is complete. Otherwise, it will simply disconnect the
user mid-transfer.

Comments? Suggestions?

Phil

Well, I never see my load go over 3 or so, but I imagine on tighter
systems it could be useful.

I suspect that would actually do more harm than good; people who want
to transfer lots of files will do it anyway, and if you cut off a transfer,
you lose that much more bandwidth when they try to transfer it again. If
you're looking to keep people from hogging connections while they're idle,
try the -t and -T options (default and maximum idle timeout, respectively).

You can build statically linked binaries under Solaris. Check the
Solaris FAQ. My ls is static compiled with latest gcc.

Another thing, make sure that the filesystem where you put your
chrooted /dev directory is mounted SUID or you'll still get the socket
problem.

Hi

I have 1100 users in my password file, and I am beginning to notice a
few problems here and there.
I have used the bigpasswd fix.

Firstly it doesn't like username longer than eight chracters. When a
user uploads it simply sets his group to a default. Is there a fix for
this, secondly alot of users are having problems logging in when they
useer something like wsftp. i seem to be able to login fine, but these
users cannot , it just says login incorrect, or can't connnect. the
thing is that I have checked the login details and they are fine, but
not even i can login myself sometimes. the problem just seems to be
getting worse, the more users there are one the system.

Any help would be appreciated

Iqbal

I agree with Perry that sending them a message when they subscribe
containing the FAQ, howto, etc. pointers is the way to go. Then if they
can't be bothered and must post, they shouldn't take umbrage at
receiving a chiding reminder about same. It might be useful to mark
the first message from a new subscriber with a signature indicating that
this is their first message to the list (dunno if LISTSERV posesses
such options). Then, if it is a FAQ question they can revel in having
to wade through a bunch of direct mail to them saying "this is in the
FAQ that was mentioned in the subscription message you were sent when
you subscribed to the list, please read the documentation *before*
sending questions to this list". :-)

Hi,

Im using wu-ftpd's virtual ftp support and i have the following
problem:

I defined a guest user to update webpages under a domain
www.something.com.
When i ftp to www.something.com using the guest user's login and pword
everything works as it should, the problem is if i login as anonymous.
The system let me in and chroot's me to / in www.something.com!

If i ftp to the machine (physical) using an anonymous login, I go to
the anonymous ftp area as it should be.

How can I set the system so that any anonymous login to a virtual ftp
goes to the machine's anonymous ftp area and the guest login goes to
the proper chrooted directory of that virtual site?

Thanks in advance,

Jose

Subject: gets nice and fast, puts take way too long
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

Installed V2.4 on a sparc10 running Slowlaris 2.5.

When I do "get"s, things hum along quite nicely. But when I do a "put", it
takes much more time to complete than it should.

My command window says this:

ftp> put fredDirections
200 PORT command successful.
150 Opening ASCII mode data connection for fredDirections.

and then it sits there.

Trussing the processes during the whole session shows that after it reads
"fredDirections" fine, this line takes a couple seconds:

ioctl(12, TCGETA, 0xEFFFE9CC) Err#25 ENOTTY

where 12 is the file descriptor for the newly created destination file.
Then this line shows up for the rest of the time it's sort of hung:

read(13, 0x0006D514, 8192) (sleeping...)

where 13 is the file descriptor for /dev/tcp.

After about a minute, it wakes up again and completes normally.

Any ideas ?

Have you installed the latest recommended patches for 2.5?

Sun cranked out a lot of tcp/ip fixes for 2.5, and some of them could make
a big difference in performance.

Guest howto, FAQ and mailing list archives, in that order, should 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.

What you want is the guestgroup access. This can be seen as a special
variant of anonymous access. So look up guestgroups in the FAQ and guest
howto. The URL's flew by in another message.

But, beware of the fact that each new rootdir needs it's own libs and
devices.

This looks like a permission problem to me. I get this error after I
login and then try to do an ls.
This is a static ls built from the gnu file utilities.
/etc/passwd is chroot'ed like /ftp/guests/./guest1
guest1 has a bin (etc,dev), directories are "by the book"

also chroot /ftp/guests/guest1 /bin/ls works!

Any and all suggestions welcome...

At a risk of telling you what you already know ...
I have just set up wu-ftpd on a solaris machine and I had the same
problem.

The cause is the device files not beeing seen. Now either they
have the wrong permissions, or else they are in the wrong place.
They must not be in anywhere other than ~ftp/dev, where ~ftp is
the path to the bacic directory that the user is chrooted to, eg
if the passwd file has -
fred:*:Fred Smith:/export/home/fred/./incoming:/ftponly
then the dev files must be created in /export/home/fred/dev

There is no escape from this as far as I know. Symbolic links are
unworkable through the chroot operation.

If you look in the man page of in.ftpd supplied by Sun, you will see
a whole section where a script is quoted showing how to create
the files. Use this and it should work.

All the best,

Hello.

Does a comprehensive archive of patches exist somewhere? I've seen
references to a couple recent patches at the Resource Center, but I can't
find patches that are mentioned in messages in this group.

Thanks.

Hello.
I am running into a problem where if I am transferring many files, after
every 10 or so, the server will hang during a data transfer. Eventually,
the client times out and closes the connection. I would like to know if a
patch exists for this problem. I know that one way to work around this is
to implement time-outs on the server (as was discussed in this group
recently), but that doesn't solve the real problem.

BTW, my server is running on Solaris 2.5.1.

Thanks.

Matt

Is it possible to configure wu.ftpd to do the following things :
- deny anonymous login from remote hosts;
- allow anonymous login from local users;
- allow guest users for all users;

Thanks

If bin is in guest1, that's not right... It looks for /bin, not
bin, so it should be /ftp/guests/bin if you are chrooting to
/ftp/guests.

man ftpaccess

I am fowlling the guest how-to directions
and I seem to hit a glich, when I recompiled ftpd with use_accessfile=1
(also tried it using ftp -a )
but with that change I now can't ftp into the server on *any* userid.

The "guest-howto" faq may say it , but I did not see that the etc, dev,
bin, directories MUST be at the chroot base directory. once I moved
bin, etc and recreated dev at the /ftp/guests base directory, the ls
command worked great. The etc directory with passwd and group supplies
the timestamps for the ls command, and the dev directory must be with
the bin directory. (It does not work to have only the bin directory at
that level, I tried it that way).
Also thanks to Godfrey Nix for the tips about dev directory, but the two
replies together is what turned on the light.

It does. From the howto:

3. Build the directory structure under Mort's account.

cd /home/web/mort
mkdir etc bin [dev lib] (dev and lib are optional and are OS dependent.)

^^^ ^^^ ^^^

4. Build the contents of the ~/bin directory.

Keep in mind, this is only if mort is chroot'ed to /home/web/mort,
not if he is chrooted to /home/web. Maybe the howto should say
to build the directories under the chroot'ed dir, not the "home"
dir (if you use /home/web/./mort)... Or maybe it already says this
since I haven't read it.

Had the same problem. Something isn't set up properly in your config
files. I used ftpchk and corrected all of the problems it signaled and the
problem went away.

ftpchk is availble at the WU-FTPD resource center.

Please do further followup on the list.

530 is a common error; grep the ftpd.c file, you'll see the causes for it.
Make sure that chuque's group is listed in the guestgroup line in
/etc/ftpaccess. Also that there is valid class/limit pair for guest
access. These are at least common errors, there are others.

Hello,
I have been reading the mailing list these couple days, and I notice
that someone mention a question that I am looking for, but there was no
answer for it. The question is that is it possible to set up the
wu-ftpd so that I can create virtual user in wu-ftpd?

First , I want to explain what do I mean for Virtual users. I want to
create a user for virtual domain bar.com so that his info will store
into ~bar.com/etc/passwd, and he can have real user access to our server
under the path of virtual domain bar.com. (for example, /home/bar.com/
will be the root directory of this virtual user.) If I can specify the
location of passwd file on a per-domain basis, I can keep my /etc/passwd
"cleaner" and easier to manage. Moreover, I can create user Joe in
virtual domain bar.com and I can also create another user Joe for
virtual domain foo.com while these two users are different people.
Right now, if I create a real user account for Joe in wu-ftpd, no other
virtual domain can create user Joe for ftp access.

I read the Document about "How to set up guest accounts", however it
does not look like what I am looking for. Does anyone know how to do
it? I will really appreciate for any comments.

rgd,
Derek

Don't think so.

There has to be something unique about each user logging in; today that is
done by a unique ID in the global /etc/passwd arbitrater. You might be
able to do this by doing a virtual Web server type hack on wu-ftpd, so
that if they come from 1.22.333.1 the DocumentRoot would be different than
coming from 1.22.333.2, and a different ~/etc/passwd would be checked.
That doesn't exist today.

Basically, this has nothing to do with ftp then, since it concerns
real users. If you just want access for ftp, then put all users under
virtual host bar.com into /home/bar.com/ , so joe's home dir is
/home/bar.com, then put him in a guestgroup with chroot(/home/bar.com).

Then if you have virtual host foo.com, they'd all be under /home/foo.com,
etc..

If you want five users named joe to be able to telnet to your machine
from different "virtual domains", then you're out of luck.

I guess this isn't clear enough for some people. Maybe we can change it
(whoever maintains it) to:

1. Do the /etc hacks. [Create the /etc, /lib, and any other directory
you need in the directory that the chroot() is done into].
