Subject: Help! Anonymous "dir" stopped working.
X-Sun-Charset: US-ASCII
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

We've been making NIS server changes and the location
of the anonymous ftp home directory, and suddenly
anonymous ftp can no longer do the "dir" command,
but "ls" still works!? (Running a freshly re-installed
Version wu-2.4(1)) on Sun OS 4.1.3_U1).

Here's what it looks like:

---------
230 Guest login ok, access restrictions apply.
ftp> dir
200 PORT command successful.
150 Opening ASCII mode data connection for /bin/ls.
226 Transfer complete. <<<<< NO OUTPUT
ftp> ls
200 PORT command successful.
150 Opening ASCII mode data connection for file list.
bin <<<<< WORKS!
etc
pub
usr
incoming
lib
welcome.msg
226 Transfer complete.
48 bytes received in 0.0013 seconds (36 Kbytes/s)
ftp>
--------

It's driving me crazy.. What's the difference?? A trace of wu-ftpd shows:

write (1, "150 Opening ASCII mode data conn".., 53) = 53
sigblock (0) = 0
sigstack (0, 0xf7fff04c) = 0
ioctl (9, 0x40125401, 0xf7ffef44) = -1 EOPNOTSUPP (Operation not supported on socket)
- SIGCHLD (20)
fstat (9, 0xf7ffefb8) = 0
read (9, "", 4096) = 0
write (1, "226 Transfer complete.\r\n", 24) = 24

So why is it not supported? What did I break? This causes all of the
applications hard coded to retrieve file lists with dir to fail.

I get the same problem. It appears the
upload line (in ftpaccess) works now (I'm
running Academ BETA 9) for all columns
except user, group, and permissions. nodirs
works, as stated in the doc for BETA 9. I
still get ftp.<autogroup>.664 - matter what
I put on the upload line.

Incidentally, in order for the upload line
to work at all, I needed to make sure that
the home directory in /etc/passwd *had* the
/./ at the end, but that in ~ftp/etc/passwd
it *did not*.

I'm running on Solaris/SPARC v2.4.

Karl,

I was also having a problem with the anonynmous ls command under wu-ftpd
2.4 and Linux 1.3.67. Then I rebuilt the ls command with the -static
flag and it worked fine. You have to specify -static in the CFLAGS and the
LDFLAGS in the Makefile (why both I don't know). You can get the source
from the fileutil's gz file, probably on the same ftp site from which you
downloaded wu-ftpd. If you can't find it, send another msg. and I'll dig
up the URL for you.

According to the deeply-buried documentation, the anonymous ftp user can't
execute a dynamically linked ls if it can't find all the proper .so files.
You could track down all the shared object libraries which ld uses, using
the ldd and trace commands. Then you can copy the correct libs into
~ftp/lib. Or you can just rebuild ls statically. Rebuilding was easier for
me. I hacked around with the .so files for a while, then gave up and went
with the rebuild.

I had the same problem. I found in the list archive that you are supposed
to be able to do a #define CMASK 022 in the config.h and solve the problem.
I am running on Solaris 2.4 and found that did not solve my problem.
sys/param.h is included in ftpd.c after config.h and if redefines CMASK to
0. Because CMASK is 0 ftpd.c uses CMASK 002. The only way I saw around it
was to change the default in ftpd.c to 022.

I would like to wrap pgp with a shell script in ftpconversions,
to allow on-the-fly pkey encryption. I have not been able to
make a shell script work there.

I am running wu-ftpd 2.4 on an AIX system (3.2.5), built with GCC.

Here is my ftpconversions line:

: : :.pke:/bin/pw festerb %s:T_REG:O_DESED:DESED

Here is /bin/pw:

#!/bin/sh
/bin/pgp -fe $1 < $2

I have installed sh and libc.a (shlib) for aix so that an interactive
chroot works.

Has anyone else used shell scripts in ftpconversions?

Thanks,
Quentin

We're running wu-ftpd under SCO OpenServer 5 without any problems other
than one involving uploads to directories NFS mounted from a Sparc running
Solaris 2.4. There are no problems downloading from such directories.

Once the client has cd'ed into the NFS mounted directory we're seeing a
failure of the getcwd() call in realpath.c. The call returns NULL with
errno=2 (no such file or dir). We're seeing the same failure when using
SCO's native realpath() call.

The really interesting part is that when the client has *not* cd'ed into
the directory but specifies that the upload is to go into that directory
it works great!

Has anyone heard of a fix for this particular problem?

Have you placed that user into the "guestgroup" as described
in the ftpaccess(5) man page?

That fixed it! Thanks. The only other prob I have is that when a user
uploads to a dir and has write permissions the file is being flagged as
rw-rw-r--
How can I set it up to me rwxr-xr-x???

In my ftpaccess I added a line that says
upload /home/ftp /tspftp/pub yes tspftp tspcust 0755 dirs

Any ideas?
Jim

Does command logging really work?

I have it switched on according to the ftpaccess file
but don't see any commands in the xferlog file.

Where else would they go by default?

Is there any other kind of logging I can turn on?
I'm trying to trace some failing transfers.

TIA

I was having similar problems until I discovered the -u option
which sets the default umask at run time.

We are running wu-ftpd-2.4 on SunOS 4.1.4.

Hi

actually, my ftp server is on a Sun Sparc 20 (solaris 2.5)
When people try to connect with netscape, they have this
message

Fatal Error 500

Can't Access Document: ftp://ftp.club-internet.fr/.

Reason: FTP-server replies: Can't open passive connection: Permission denied..

How to solve it ?? I use the 2.4 version of wuftpd.

Thanks for all help

The problem is the firewall. I had the same problem. I was only allowing
through src TCP connections above 1023 for ftp-data. You also have to allow
dst UDP and TCP connections above 1023, otherwise the PASV mode cannot be
negotiated.

While Netscape is good for many things, it causes problem in many other
things.

Command logging goes to syslog using the daemon or ftp facility.

They are logged via the syslog facility. See syslog.conf to see where
that information ends up.

I have been looking for docs that might explain differences/gotchas for
wuftpd under Solaris 2.4. It seems to me that things must be different,
what with shadow passwd files, nsswitch, and the like.

My real problem is that with the same ftpaccess file and setup stuff that
worked on a SunOS machine, no user can get in at all onto my Solaris
machine.

Help...? Please...?

Thank you,

Subject: self contained virtual ftp servers?
Content-transfer-encoding: 7BIT
X-Sender: [email protected]
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

Greetings,
I'm using wu-ftpd beta 9 to provide several virtual ftp
servers. Each server has its own separate ~ftp, complete with
binaries. Is it possible to keep the information that controls access
to each individual server in ~ftp, or is this a very bad idea?
Alternately, does a mechanism exist to separate the access control
information into separate files not in ~ftp? I'm trying to allow teh
"owners" of each virtual server to do their own access control without
submitting requests to me.

Thanks,
Stephen

I am trying to setup wu.ftpd to allow uploads to the incoming
directory, and downloads from the pub directory. I have changed owner
of bin, etc to root, and incoming and pub to ftp. I have given the
the incoming directory rights 722 and 766
drwx-w--w-
drwxrw-rw-
I have given the pub rights 744
drwxr--r--
When an anonymous user makes a new directory, it gets the rigts 775
drwxrwxr-x
They can not upload files in their created directory.

I am not to familiar with the ftpaccess file, but I followed the man
pages and attempted to make any changes needed. The upload area looks
like this:
/home/ftp no *
/home/ftp/incoming yes ftp anonymous 0722
/home/ftp/bin no
/home/ftp/etc no

Any help is appreciated.

Subject: SITE EXEC?
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

I'm trying to work out a system whereby our non-anonymous users can find
out their disk quotas from within ftp (they don't have telnet access).
SITE EXEC seemed as though it would be a good way to do this, and I've
written a small C socket client that contacts a server daemon running on
the machine (in the "real" filesystem, not the chroot'd one) that grabs the
user's UID, runs the quota command, and passes back the result.

This client and server work fine if I'm not trying to SITE EXEC them from
within ftp, but I can't seem to get the SITE EXEC stuff to work:

ftp> site exec quota
200-quota
200 (end of 'quota')

I've tried all manner of paths to get there...

Any ideas? I've looked around for hints on SITE EXEC, but haven't found
any.

Many thanks.

For accounting, I have been trying to implement a virtual server name
logging mechanism into the latest WU-FTPD 2.4.2 b9 without much
success. I thought by keeping the virtual ftp server's hostname and
then write it out later this could be accomplished, but names don't
show up somehow :(

Right now, our machine has some virtual ftp servers running on it, but
since the log entries are written after the chroot(2), so anonymous
ftp entries all show up as rooted at /, pretty hard to tell which
virtual ftp server was used :(

Any suggestions?

To reduce system load and to keep system security level higher, our
web servers don't grant user shell level access. This creates an
interesting problem. The user home directories are their respective
document_root for the HTTPD; now, if each account's virtual ftp server
is rooted at the account's home directory, obviously even an anonymous
ftp user can look around in the entire directory tree rooted under
this user home directory. This defeats the purpose of placing password
access control files in such directories as even the web server will
prevent unauthorized accesses, the virtual ftp server mechanism, as
far as I can tell, doen't have such capability. This creates a sysadmin
problem as kludges have to be used to separate user's stuff for ftp
and for web at different places. It also complicates user file maintainence
too.

I don't have a clean solution yet and would like to invite some suggestions.

Thanks,

I had submitted some patches, against beta9, that changed the
format of the virtual ftp config options, and allowed you to create a
seperate log file for each virtual domain. I've been running it here
for several weeks now, without any problems.

Dear Marc,

Thanks for pointing this out to me. I would love to see your patches.
I basically tried to kludge one more entry after the

#ifdef STUPID_SPRINTF
/* Some sprintfs can't deal with a lot of arguments, so we split this */

in the ftpd, but somehow my own stuff doesn't work.

Could you point out to me where to get your patches? I just checked
ftp.academ.com's pub and pub/wu-ftpd/private, didn't see anything.

Would you please email me a copy?

I am particularly interested in knowing whether it's likely to run
into file descriptor problems with such an approach. I believe
that some web servers also allow separate log files for virtual
web servers, but that approach typically creates headaches after
some OS dependent number of virtual web servers are built.

Thanks and best,

Chin Fang

Depending on how quickly you need it, I just put a full .tar.gz file
of .beta9 with the patches in ftp://ftp.ki.net/pub/users/scrappy. I'm
going to pull a fresh copy of beta9 and do a diff against it, but don't
seem to have one laying around the system right now :(

There is an 8k .gz file available at:

ftp://ftp.ki.net/pub/users/scrappy/wu-ftpd.diffs.gz

That will go against a "clean" beta9. The patch includes
various stuff for FreeBSD, as well as modifications to the original
Makefile.fbs.

The format for the config entries change to:

# Virtual Servers
virtual <ip> root <chroot directory>
virtual <ip> banner <banner msg - optional>
virtual <ip> logfile <logfile - optional, defaults to "system logfile">

Dear Marc,

Many thanks for the pointer. Will take a look of your patch and see
where I goofed up :(

I just tried ftp.academ.com pub/wu-ftpd/private:

ftp> get wu-ftpd-2.4.2-beta-9.tar.Z
200 PORT command successful.
150 Opening BINARY mode data connection...

So Stan has got his copy around.

Thanks again,

I think it would be pretty neat to add a "Max Hops" configuration for
the groups, so that instead of defining a "local" group by a domain, you
could define it by hops.
Anybody have any idea how tough this would be?

I am trying to get wuftpd working on solaris 2.4.. Its 2.4 wih the virtual
hosts patches using gcc 2.5.6 ... We only recieve this error message when
trying to connect as anonymous; all other users are fine. My supposition
is that it simply cannot figure out what host is calling it. If you have
any ideas as to why or can point me towards more informatin, I would
greatly appreciate it.

thanks.. d.p.

Took me a lot of reading en trying one time. To send a command to the

quote command
So it becomes:
quote site exec quota.

I hope this helps,

Not too difficult, I imagine, but the number of hops between any two sites
is not, of course, a constant. This could cause real (perceived) weirdness
from the user perspective. "Sometimes I get through, sometimes I don't, for
no apparent reason."

I am trying to diagnose / problem-id
a persistent problem we've been having with lost
connections.

It originated with one particular user
(who happens to use guest ftp) who uses
large files, and I assumed it was
purely size of file that was the basic
problem, but on investigation, it doesn't
seem to be particularly related to file size.

In fact it turns out that we've been getting
many more lost connections than I would have guessed
e.g. 20 / hour on a bad day.

It seems that these are quite distinct from "timeouts",
which we also get, but much less (usually < 1/hour).

I've been looking for patterns, clusters, other activity, etc,
that might be related, and can't really see anything.

Does anyone have any feel for what can cause a "lost
connection"?

Hitherto, I would have thought this was usually a
timeout, but as far as our logs are concerned, they
seem to be quite distinct events.

TIA,

I am trying to install pgp as a filter in ftpconversions in order
to encrypt files as they are transferred. I have installed a line
like this in ftpconversions:

: : :.joe:/bin/pgpw joesmith %s:T_REG:O_DESED:DESED

/bin/pgpw is a wrapper around pgp that causes pgp to encrypt the
file argument with joesmith's public key. I have tested pgpw in
a chrooted environment and it does work well. pgpw writes the
encrypted file stream to stdout (as does pgp).

However I cannot make it work for ftp transfers. I see this when
I try:

ftp> get passwd.joe
200 PORT command successful.
150 Opening BINARY mode data connection for /bin/pgpw.
226 Transfer complete.
ftp>

The file transferred (passwd.joe) is zero-length.

I have been able to install other filters successfully. The difference
is that pgpw is a wrapper around another binary, and I cannot make
such a wrapper work. (Wrapper is necessary because pgp in filter mode
demands its input from stdin, rather than from a filename on the
command line). I have included my wrapper (pipe stuff) below.

Has anyone else solved this problem?

Details:
IBM AIX 3.2.5
WU-FTP 2.4

Thanks,
Quentin

/*

This does not work yet!

Run this program as:

pgpw userid input-file

and it will run pgp like this:

pgp -fe userid < input-file

This is also designed to work in a chrooted environment, where
pgp is found in /bin/pgp. Won't work outside such an
environment without changing the pgp path.

Been there; tried that. Weive tried the static libraries with no luck.
The problem is not only with ls but with get and put, etc,etc - and ONLY
as anonymous. Normal users are fine. Are there any other place to look or
ideas to follow.

I've been using the Virtual FTP versino of wu-ftp for a while now.
However, it would be usefull if the xfer logs for virtual sites were
either in different files, or put the ip address of the virtual server in
the log, so that accesses could be told apart.

I prefer different files.

Is anyone working on this ?

Subject: Another SITE EXEC question
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

I'd written:
I'm trying to work out a system whereby our non-anonymous users can find
out their disk quotas from within ftp (they don't have telnet access).
SITE EXEC seemed as though it would be a good way to do this, and I've
written a small C socket client that contacts a server daemon running on
the machine (in the "real" filesystem, not the chroot'd one) that grabs the
user's UID, runs the quota command, and passes back the result.

This client and server work fine if I'm not trying to SITE EXEC them from
within ftp, but I can't seem to get the SITE EXEC stuff to work:

ftp> site exec quota
200-quota
200 (end of 'quota')

I've tried all manner of paths to get there...

Any ideas? I've looked around for hints on SITE EXEC, but haven't found
any.

The first problem was fixed by RTFReadme - since this was non-anonymous
ftp, I needed to have the command in /bin/ftp-exec (relative to the top of
the chroot'd user tree) <duh>. This at least got the execuatable seen.

However, it still doesn't work. I'm using getpwuid() to try to figure out
which user is running the command - this doesn't appear to be working, and,
in any case, I'm not getting output the client program sends.

How _does_ SITE EXEC work? Is there something obvious I'm missing?

Thanks.

>From the world-famous wu-ftpd-faq (which also answers the question where

7. Programs (ls, gzip, tar) work for real users, not for anonymous
users, giving errors like 425 Can't create data socket
(0.0.0.0,20): Bad file number or simply no output.

First, consider if you can't relink them staticly so the shared
libraries aren't needed. You can get the GNU fileutils from :
<URL:ftp://prep.ai.mit.edu/pub/pub/gnu/fileutils-3.12.tar.gz>
(version numbers may vary).

For different operating systems, different libraries and/or
devices are needed. You can test if things are running correctly
by doing a chroot to the ftp homedir. To test if /bin/ls is
working in the ~ftp dir, type :

chroot ~ftp /bin/ls

1. Solaris
Solaris needs ~ftp/dev/tcp and ~ftp/dev/zero and the
libraries. Check the man-page for your Solaris version for
exact details. Use the command truss to find out which
libraries a program uses. Also, the ~ftp/etc/group file is
needed for ls to work, without it it will just dump core.
Follow the same rules as for /etc/passwd : not too much
information in that file, like group passwords (if you have
those).

Problem with /etc/group found by Eric ([email protected]).

Dear Chris,

I worked on the 2nd approach for a while, even thou I put it aside for
now after Marc told me about his patches. He is right in that using
separate files, existing log analyzers work out of box.

Basically, what I wanted to do is to capature the virtual host name
in the ftpd.c, and then slightly modify the sprintf in the log msg
writing portion after Hobbit' comment.

For some reason, it didn't work :( I will look into this later on.
For now, I am very happy finally I have a way to tell which virtual
ftp server carries most the traffic. Good for accounting.

You may wish to look into the approach I mentioned above. After you
are done with it, pairing together with gnu grep and any one of the
standard log analyzer, it's not too bad.

I think single file plus a rotation policy is also allright too.

Excerpt from: http://www.huv.nl/~koos/wu-ftpd-faq.html,

3.Where do I get the wu-ftpd ?

The wu-ftpd home is wuarchive.wustl.edu, the exact URL is:

ftp://wuarchive.wustl.edu/pub/unix/wuarchive-ftpd/

This daemon is available in source code and binaries from many
other ftp-sites, ask _archie_ where to find it. Best is to compile
it yourself, since it has a lot of compile-time options.

1.Where do I get the updated version ?

The above is the last version created by wuarchive. On the
mailing list, an updated version has been created which is
maintained by Stan Barber ([email protected]).

You can get this beta by ftp from the directory :

ftp://ftp.academ.com/pub/wu-ftpd/private/ the directory is not
browsable, a .message file will point you to what is the latest
version. Read this .message.

Remember, these are BETA versions. Before asking/trying
anything, check first that you have the latest version. And if
you run this version, keep up with the list to make sure you

I'm running version 2-4 on Digital UNIX 3.2-c since quite a long time and since
last week, I find every morning more and more users still "logged in". In fact
they have left but there are still in the list given by the ftpwho command.

If I try to connect and to quit from another computer, it works and after the
"quit", I'm no more in the list.

Why these processes are still there ?

Thank you.

Daniel

I was wondering if there was any way to get the wu-ftpd to place =
anonymous users in different directories according to the IP =
address they are communicating with. I have a machine running =
SunOS 4.1.3 and using vif to do multiple IPs on one ethernet =
interface. I would like to have anonymous ftp logins to the =
different IP addresses use different local directories. Is there a =
patch or configuration option that I can use to achieve this?

thanks,

Hello,

I have configured wu-ftp 2.4 and everything works fine
except that ftp users can telnet into the server and look around.

How do I restrict or prevent ftp users (belonging to the
guestgroup) from telneting into the server and looking around?
Should there be some shell script in the dummy shell that
prevents them from logging in using telnet?

I have tried using the restricted shell /etc/Rsh but I noticed
that I could change shells and get around this.

I have changed the ftp login shell back to a dummy shell.

ftp1:x1x/U/RNMo34k:405:400:ftp1:/usr/local/home/ftp1:/bin/ftponly
ftp2
..

They belong to the same group in etc/group:

ftp:*:400:ftp,ftp1,ftp2,ftp3,ftp4

And this group if defined in the guestgroup table in /ftpaccess;

# specify which group of users will be treated as "guests".
guestgroup ftp

Thanks in advance.

What about /bin/false. But make sure you add this to your /etc/shells or they
wont be able to ftp at all.

Appended here is s small C program which can be used as the
user's shell in /etc/passwd. I think it does the job nicely.

Thanks Ken for the your suggestion.
When I telnet into this account now I get logged out. ftp works
fine like before.
Can you explain what this /bin/false shell is and what it is used for?
Is this what everyone sets as a shell when creating
secured (requires password) ftp accounts?

Thanks again!

Ken,

Is that OS specific? because I couldn't even find the file (/bin/false) on my
BSD unix (2.1).

Thanks.

That surprises me, but you can always make one by coding up a
shell script or compiled program that returns a value of 255.
You can also have /bin/true return a value of 0.
Good luck,

after reading the FAQ, it seems that wu-ftpd running on a solaris machine
needs the following files ~ftp/dev/tcp and dev/zero

but these devices (as far as i know) can not be "cp" ... could someone
tell me how to get these files (or dummy versions) into ~ftp/dev

thanx

cd ~ftp/dev
mknode zero c 13 12
mknode tcp c 11 42
cd ..
chmod 555 /dev

Hope this helps...

Subject: SunOS 4.1.4 DIR problem solution (should be in FAQ)
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

Here's what needs to be done in order to make anon FTP work with DIR
under SunOS 4.1.4. Also, you can define "guestgroup customer" in
your /usr/local/etc/ftpaccess file, and create a group "customer" in /etc/group.
This will allow you to have a class of users who can have their own
secure FTP areas, but can't prowl all over your system.

Here is my directory tree:

~ftp:
total 5
d--x--x--x 2 root 512 Dec 5 14:48 bin
d--x--x--x 2 root 512 Jan 4 14:13 dev
d--x--x--x 2 root 512 Jan 4 15:03 etc
drwxrwxrwx 2 root 512 Nov 28 19:46 pub
d--x--x--x 3 root 512 Jan 4 15:05 usr

~ftp/bin:
total 550
---x--x--x 1 root 24576 Nov 28 15:02 compress
---x--x--x 1 root 90112 Nov 28 18:37 gzip
---x--x--x 1 root 13352 Jan 3 18:55 ls
---x--x--x 1 root 425984 Nov 28 19:16 tar

~ftp/dev:
total 0
crw-rw-rw- 1 root 3, 12 Jan 4 14:13 zero

~ftp/etc:
total 7
-r--r--r-- 1 root 299 Nov 28 19:45 group
-rw-r--r-- 1 root 4096 Jan 4 14:26 ld.so.cache
-r--r--r-- 1 root 151 Nov 28 19:58 motd
-r--r--r-- 1 root 71 Nov 28 19:24 passwd

~ftp/pub:
total 0

~ftp/usr:
total 1
d--x--x--x 2 root 512 Dec 28 13:45 lib

~ftp/usr/lib:
total 608
-r-xr-xr-x 1 root 40960 Jan 4 14:11 ld.so
-r-xr-xr-x 1 root 548864 Jan 4 14:11 libc.so.1.9.2
-r-xr-xr-x 1 root 24576 Jan 4 14:11 libdl.so.1.0

To create ~ftp/dev/zero, use: mknod ~ftp/dev/zero c 3 12
You also need to be sure that /etc/ld.so.cache is copied into the ~ftp
tree, as well as the libraries listed above.

After several weeks of working on this on and off, it finally WORKS!!
I did some careful pruning to make sure that there isn't extra flotsam
in the ~ftp tree which isn't really needed.

Here is a little script I whipped up to create FTP trees for customer
use. Modify the /h/customer reference below for where you keep your
ftp trees. The ~ftp tree must be kept in the same place for this to work.

----- start script -----

#!/usr/bin/csh
#
# makeftp - create FTP tree for a customer
#
# Syntax: ftp userid
# userid is customer's user ID (must already have been created in /etc/passwd)
#
if ($#argv != 1) then
echo "Syntax: makeftp userID"
exit
endif

# validate the user ID
if ! { fgrep $1 /etc/passwd >/dev/null } then
echo "Invalid user ID - create the user login with vipw first."
exit
endif

# user ID is valid, clone various parts of the ftp user tree
cd /h/customer
mkdir $1
cp -pr ftp/bin $1
cp -pr ftp/usr $1
cp -pr ftp/etc $1
mkdir $1/dev
mknod $1/dev/zero c 3 12
mkdir $1/data
chown -R $1 $1
chmod o-rw $1
chgrp -R customer $1
chmod og-rw $1/data

---- end script ----

Cheers,
Tim

When you use anonymous ftp, wu-ftpd will chroot to ~ftp, and
/usr/lib/libc.so.1.8 are no longer visible.

There are two possible solutions:
1. copy /usr/lib/libc.so.1.8, /usr/lib/ld.so, /usr/lib/libdl.so.1.0 to
~ftp/usr/lib, OR
2. recompile 'ls' with -static.

Check whether kaneda is using a shell not listed in /etc/shells,
e.g. /usr/local/bin/tcsh. If not, add it to /etc/shells.

Create /etc/shells and put the name of the user shells in.

/bin/sh
/bin/csh
/usr/local/bin/tcsh

The paths the shells may be different on your system.

Hi, read the man page about 'mknod' that explains hov to create /dev/zero or
other files like that.

Hi, try this:

cd ~ftp/dev
(cd /dev; tar chf - tcp zero) | tar xf -
chmod 644 tcp zero

Hope that helps!

Not being an expert, but someone taking a guess.

The problem with real users denied access is that there needs to be an
/etc/shells file with a format like

# /etc/shells - this file exists for wu-ftp
/bin/sh
/bin/csh

and this file needs to list all the shells that users could login with or
they will be denied access if that user's shell is not listed.

The other problem has to do with making ls available for execution to the
users. Place a copy of ls in the ~ftp/bin directory that shoudl help.

I beleive tha answer is yes but I would have to check on the option flags
to tell you the syntax.

Check ~wu-ftpd/docs/ftpaccess.heavy
for a well documented example.

I'm not sure where I saw it recommended, but I use /etc/ftponly
which is simply a symbolic link to /dev/null.

The idea is that ftponly can be in /etc/shells so you can use /bin/false
for accounts that need to be disabled totally.

(Not applicable in your case I think, but in AIX systems, one
can set the username to be "telnet=no" via the chuser command.
(also "login=no, rlogin=no, su=no").

It's obviously also a good idea to take the precautions already
mentioned by others, just in case there are any loopholes in the "telnet=no"
etc. mechanisms in AIX.

It is a shell scripts that exit with 1.

The better way to create ftp only account is to use guest login. Define a class
in ftpaccess, the account will be chroot to their home directory(just like
anonymous). Therefore, they can't access the real / or /etc. O'Reilly 's book
"Managing Intrernet Information Services" has full detail.

Well, I found my problem:

anonymous user was working fine.
real users was working fine too.
but some real users were getting 0.0.0.0.20 socket error.

The users who where getting this error were included in a virtual ftpd group.

Let me explaine this.

I have this in my passwd:
user1:x:100:10:user1:/home/user1:/bincsh
user2:x:101:10:user1:/home/user2:/bincsh
crazywolf:x:222:300: Ftp for group crazyguys :/www/./crazustuff:/bin/false

and my group file has

group1::10:user1,user2
wwwcrazy::300:crazywolf,user1
^^^^^^^^^

The reason I puted user1 into the group wwwcrazy is beacause I wanted to
give him access directly from the shell,( doing simple modifications with
vi, etc..)

This was doing the bugus thing, as soon as I removed the user1 from the group
wwwcrazy, the realuser connection started to work fine.

Is this a bug ?

have a nice suny warmy day

It's something like:

"The processes don't..... [that I did not understand, even though I am a
native french speaker, probably a typo or missing word]."

"I have got hundreds [ of dead processes, probably] like that every week."

PS: Now could a native english speaker translate my translation to
english? I have this feeling that it's far from being grammatically
correct.. :) :)

Yep, I've seen and I've fixed (using a patch provided by one of the reader's

Hello,

What is a passive ftp connection?

I've built an ftp server and upon giving one user a private account
they sent me the following error. I cannot find anything about this
in the O'Reilly book (Managing Internet Info Svcs) nor the wu-ftpd
docs.

TIA,

Subject: question on upload statement in ftpaccess
Mime-Version: 1.0
Content-Type: Text/Plain
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

I'm running into a problem whereas the files uploaded from a guest user on ftp
doesn't have an owner/group and mode that I specified on /etc/ftpaccess. The
owner and group follows from the parent directory and the mode is always 755.
Any ideas?

Here is a copy of my /etc/ftpaccess file :

---------starts here

upload /var/spool/upuser/upuserall * yes root daemon 066 dirs
upload /var/spool/ftp /bin no
upload /var/spool/ftp /etc no

# directory aliases... [note, the ":" is not required]
# alias inc: /incoming

# cdpath

# path-filter...
path-filter anonymous /etc/pathmsg ^[-A-Za-z0-9_\.]*$ ^\. ^-
path-filter guest /etc/pathmsg ^[-A-Za-z0-9_\.]*$ ^\. ^-
--------------ends

So in this case, all the files/dirs that upuserall created doesn't have an
owner of root/daemon and the mode is 755.

Thanks for any input.

Thank you for the translation. Unfortunately what he said is not
horribly useful.

What we have is an ftp-daily that runs every night and amongst other
things kills off these processes if they are older than 24 hours.
Not too elegant but it works. I would really like to know what's
causing it though.

Depends what you mean by English I guess. British, Canadian
American, Austrailian ...

Since there are regular mails in this list with a patch for hanging ftpd's
I never have this problem on our hosts. We run the ftp-server on
SINIX5.42 (SVR4-based) without any hanging ftpd (after using the patch !!).
I don't know, why this patch don't find the way to the beta-releases
of 2.4.2 :-(
By the way, I see the Problem also an IRIX4.05 and IRIX5.2 .....
But as long as there exist friendly people on this list who mail the
patch short after a new beta-release, it's no problem for me.

You have /bin/false as ftp's login shell, but only /usr/bin/false in
/etc/shells. Could this be the problem?

Using wu-ftpd 2.4.2-beta9 on Linux and I'd like to know if there is a way to create an
upload only user. They should be able to browse around the directory structure, but
simple can't do any gets. Is this possible?

Is there a security or other functional reason for not using the "+" sign in
the ftpaccess path-filter character list for ftp? I need to use it and was
just wondering if there was a reason it wasn't part of the default set. I am
running wu-ftpd-2.4.

I am getting continuous complaints about interrupted uploads
to ftp particularly for big files. They are not limited to modem
uploads, but also over ethernet from other sites.

The evidence of these broken uploads is a continuous accumulation of
hung ftpd processes which I have to clear out periodically, something
y'all have been talking about recently.

One thing that has not been brought up is the earlier problem of
the broken connections in the first place.

This seems to be a serious problem that I can not discount as
dirty lines any more.

OK I have beta-9 and now I have this _tiny_ problem

I would like to use virtual portion of this however on solaris 2.5 x86
this blows up... with MAXNAMELEN being redefined.....

Then I decided to build a single now and worry about the rest laster so I
did ./build sol CC=gcc CFLAGS=-02
and this blew up for no apparent reason..

However doing ./build sol CC=gcc everything compiles fine.. (few warnings)

any clues...

Also if the people at ACADEM.COM are on this list I would be more than
willing to give you an account on this machine so you can possibly see if
you can get it to compile....

Thanks

When reporting any problems, it is most helpful to include some details
about your environment. What kind of computer are you using? What OS is
running on the computer? What version of wu-ftpd are you running? What
version of a c compiler did you use when building it?

Without this information, it is impossible to do much to help you with
your problem.

Okey. Let me know. I have not tried to make it work on Solaris 2.5 of any

I compiled it on Solaris 2.5 just fine, and it is working well, chroot()
dir's, ftpconversions, and all.

People talking about chronic hangs uploading to ftpd, a serious
problem on our system. Some of it is client side software as
the below discussion indicates.

light is our main server.

K.,

Well, at this point I'm blaming Apple more than anyone else.

The problem happens with both Anarchie and Fetch -- and only with light.
I'd be tempted to blame light's ftpd, but even if it were flakey -- and I'm
not convinced it is -- the Mac still shouldn't be hanging and needing
rebooting.

But yes, it is annoying that Fetch is so much slower when it makes Open
Transport calls. In this case it hangs uploading to light too.

I'm tempted to put together an FTP tool using some sample code I've got
lying around, because that would either give me something that works or a
framework in which to learn more about what's going on. But life is short
..

[discussion snipped for brevity]

Do you happen to have a shell account(Unix or VMS, whatever) where you can
test to see if the problem occurs with that as well. If so, then likely it
is ftpd...otherwise, I would attribute it to the combination of OpenTransport/
Fetch. Remember...OpenTransport is *really* new and is as such, has plenty
of issues still to be resolved. I finally went OT yuesterday..Fetch
works well for me, although I identified at least one scenario where a
screwy program can 'halt' the data stream for other programs, causing them
to go nuts. Fetch handled it pretty well, but didn't continue.

There's a program that cleans up hanging open TCP connections whenever a
program is invoked - mail me for a copy if you're still having problems.

Have a look in your syslog.. first hunch is that the ftpd coredumps.

Looking in your syslog (if set at appropiate levels) can help debug a lot
of problems.

Dear people at wu-ftpd list,

I subscribed long ago this list looking for a solution on the problem I
report later, I did already ask for it time ago, but got no solution.
Amongst the interesting discussions in this list I have never heard
again on the topic I posed, although I thought it was a very common
problem to ftp-masters. Ok, as I have found out more things I tell you
the whole thing:

Having symlinks on your ftp hierarchy is a cause of confusions to
ftp-users due to the way wu-ftpd treats them. wu-ftpd as well as some
shells does a real 'cd' each time you get into a directory, so if we are
in a directory 'os' with subdirectories:

linux -> symlink to ../../mirror/linux
FreBSD
..

and we do a cd into linux and then a 'cd ..' back, one does not appear
at 'so' but at mirror, so you go forward and backward and appear in
another place.

Bash, funet-ftpd and others treat this problem by not doing actual 'cd'
but keeping somewhere the path where you are, and applying it to the
commands as needed, while maintaining actual path to the root of the
ftp. You have to add code for doing the changes in the path variable
every time you do a 'cd' or similar.

A possible solution is to do NFS loopback mounts or just loopback mounts
in the operating systems that support it ( Solaris lofs ). This solution
works right, but it gets unmaneagable when having hundreds of symlinks (
this comes when you have contents accesible through different structures
).

As once I saw an ftp site (sunsite.doc.ic.ac.uk) that runs wu-ftpd and
treats symlinks this way, I asked their managers ([email protected])
for how they do it. After several messages in a wide range of time I got
response, telling me they patched the server and posted the patches to
the people who maintains wu-ftpd, and I should get them from there.

I sent an e-mail to the people who maintained wu-ftpd in the past ( I
got the address from http://freeway.oact.hq.nasa.gov/wuarchive.html ),
but got no response. Maybe I did not send it to the correct place.

As many people here is maintaining the current development of wu-ftpd, I
would appreciate a lot if someone can tell me anything about those
patches.

I would also like to know if someone has developed patches for directory
names hidding.

In case no one has ever heard of that I would like to get advice on
patching wu-ftpd, i.e. how to do it for making it useful for people
other than me.

Thanks for your time.

Same here. Do you get "lost connection" messages in the debug log?

It would seem that there is no retry facility in the protocol,
at least not an effective one. (Anyone more knowledgeable care
to comment?)
Is there potential for improvement here in a future BETA?

I think it would be best if the Academ people added my work into their
definitive version.

However I'll see about making a version of my patches available, relative
to the current Academ release (which I think is 2.4.2-beta-10).

I'll email to this list when its done and where to find it.

I am trying hard not to add to many new features to the current release
so I can get it to release and move on to version 2.5. I would be delighted
to put such features into release 2.5 (which is after 2.4.2 becomes release).

I've got something similiar.

I applied Vidiot's patch tp ftpd.c (Sorry, I forget your email address),
and it now removes processes that hang retrieving files. But every now
and then a process will hang when storing a file.

One of my users frequently hangs a ftp storage process. He uses crl.com,
and they are running SunOS 4.1.3, and his ftp client is /usr/ucb/ftp.
He'll upload several files (usually they are small (<100k)) and then it
will hang. He told me he waits a minute, then shells out, kills the ftp
client process on his side, and opens another and re-does the transfer.
Unfortunately, upon killing the client, the server process is now stuck.

I've got some other instances I'm trying to track down hung storing
processes.

I'm running BSDI 2.0. In all honesty, I think these patches that kill
hung connections are a band-aid to the real problem. I'm still running
beta-9, and probably will install beta-10 sometime this week or this weekend.

Even though the machine is the home of the Apache web server, we still
need ftp! :)

I've just upgraded my anonymous ftp server to AIX 3.2.5.1, and
find that part of the wuftpd package has been crippled as a result.

wuftpd allows auto-display of a file when anonymous users change
directories. (This is enabled with the 'message' command in the
ftpaccess file.) Since the 3251 upgrade, users get the first few
lines of the messages file, but then their connection to the ftp
server is broken. Turning on wuftpd debugging tells me that
a SIGSEGV (signal 11) is being generated.

is very much appreciated. Running on BSDI.

Well, now I did it.

I'd appreciate if other users/admins could attempt to duplicate my results
just to see how valid they are.

Symptoms: interrupted transfers

Host environment: BSDI 2.0, wu-ftpd academ beta 9, Vidiot's "hung connection"
patch applied.

Client environments: SunOS 4.1.3 running command line ftp
Windows NT 3.51 with ws_ftp 951229 32 bit
another user said he had problems with ws_ftp 32bit 9508??, unknown OS.

Line quality: SunOS T1; Win NT 28.8 PPP. I tested Win NT myself - line
was relatively responsive and lag-free. Not sure about other cases I've
had.

Files transferred: 60 files comprising 1.9mb of disk space. Some were text
files; some .zip files, some binary files. Most in the 10k-30k range,
some 100k, largest 600k, smallest 134 bytes.

I fired up ws_ftp at home, ftp'd to my machine, created a directory on
the host, selected all 60 files on my machine, and hit the upload button.

Sometimes after the transmission of a file, there is an extreme delay.
Killing the ftp client during this delay (1-5 minutes observed) leaves
a hung process in a STOR state (as reported by ftpwho). Occasionally
this recovers and proceeds to the next file. I've tried uploading the
60 files numerous times (removing them from the host before transfer),
and I can't get consistent results. Usually it blows up somewhere along
the way.

My current transfer is in a hung state right now. ws_ftp's status window
indicated the transfer suceeded, reporting the correct number of bytes
for this file, and a decent transmission speed of 6.86KBps. ws_ftp's
log has not been updated to reflect this upload yet. The ftp process
on the host is still STOR'ing, as I said above. I've been waiting for
about 20 minutes now.

No firewalls involved. I was logged in as myself, not as 'anonymous'.
The host had a loadavg of .19 (good), and had gobs (35MB) of free RAM
as shown by 'top'.

Can someone else attempt to transfer a mess of files to see if they can
duplicate anything with regards to hung connections and report back?
I'd be most grateful.

It might be a good idea to stress-test wu-ftpd like this over and over
and over to see if it can fail. I noticed this hanging connection
problem when I started using the Academ beta's. I think the patches
posted to the list are a band-aid for the real problem, which oughta be
fixed.

Any thoughts? Before testing, it might be a good idea to turn on logging
in your ftp client, if that's possible.

It's even a better idea to test with the lastest beta. It has one other
patch in it that may help with this. The test you ran was on old code.

Anyone else having trouble with the banner facility in 2.4.2 beta 10?
My problem is that wu-ftpd is not displaying the welcome.msg. When
I turn on debug mode, I see the lines of the msg being sent, but without
the proper codes in front of them.

Is this a known bug? Or am I still doing something wrong?

With beta 10, mkdir has stopped working for my user accounts. It properly
doesn't work for anonyomous users which is what I want. I've tried
several different upload keyword schemes in ftpaccess to no avail. If anyone
has some working examples that they can provide, it would be appreciated.

Try ensuring that the home directory field
in /etc/passwd for the ftp user has the
"/./" on the end and that it does *not* have
it in the ~ftp/etc/passwd file.

Subject: Eratta in wuftpd2.4.2-BETA10
Mime-Version: 1.0
Content-Type: text/plain; charset="us-ascii"
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

Specs:

wuftpd-2.4.2-BETA10
Sun Sparc 20
Solaris 2.4
compiled with gcc, using ftp.h from wuftpd-2.4.2-BETA10 distribution.
The compile was perfectly clean, no errors at all.

There are two things I noticed:

1: Virtual ftp "sites" do not correctly interpret classes.

Example: In the portion of a sample ftpaccess file shown below, I
can log in as a local user to the default IP address and/or name of the
server, but when I try and log in to the virtual server, either by IP
address, or name, as a user who should be classified as local, it puts me
in the remote class.

# Virtual Server test for IP x.x.x.x
virtual x.x.x.x root /export/ftp2/
virtual x.x.x.x banner /export/ftp2/msgs/msg.welcome
virtual x.x.x.x log /tmp/xferlog

class local real,guest,anonymous *.mydomain.dom x.x.x.*
class dialup real,guest,anonymous d*.mydomain.dom x.x.x.*
class remote anonymous *
class regftp real,guest *
class test real,guest,anonymous mydomain.dom x.x.x.x

limit local 10 Any /etc/msgs/msg.toomany
limit dialup 20 Any /etc/msgs/msg.toomany
limit remote 30 Any /etc/msgs/msg.toomany
limit test 40 Any /etc/msgs/msg.toomany

2: Not really a bug, but here it goes:
If I log in from mydomain.dom, and there is a more open mask in
ftpaccess, ex *.mydomain.dom, it places me in the class that is least
restrictive. An example is if I want one computer, mydomain.dom to have 40
users possible, and the rest of my domain to have only 10 users, I can't.
It seems I either have to make a class for each "computer," or allow/deny
the entire domain.
If anyone knows of a way to make *.mydomain.dom have one limit, and
computer1.mydomain.dom have a different one, I'd be much obliged.

If anyone has a solution to problem #1, I'd also be much obliged.

Subject: [2.4.2-BETA9] Illegal seek (ESPIPE)
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

Hello,

Using wu-ftpd 2.4.2-BETA9, I frequently get the following error message:

150 Opening BINARY mode data connection for /bin/tar.
====> 426 Data connection: Illegal seek.
local: docs.tar.gz remote: docs.tar.gz
1409924 bytes received in 14 seconds (98 Kbytes/s)

Then the bytecount is also wrong: it's slightly less than the correct
size of the gzipped tarfile. And it always happens when the file is
nearly finished, although at different places just before the end.

This only seems to happen when getting tar'ed directories in combination
with gzip. I guess ftpd gets an ESPIPE errno (Illegal seek), which means
it calls lseek(2) on a pipe, socket or FIFO.

I'm using Linux 1.3.75/76, gcc 2.7.2, libc-5.2.18.

Is this a known problem? Is there a patch?

Subject: Couple of questions
MIME-Version: 1.0
Content-Type: TEXT/PLAIN; charset=US-ASCII
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

I have the following questions. My platform is SPARC 5 running SunOS 4.1.4.
I had no compilation problems and practically everything works as advertised.

1) What is the secret to getting the automatic tar and compress to work?
I have tried everything I can think of regarding the ftpaccess file.
Specifically, the three entries I thought were key are:

class all real,anonymous,guest *
.
.
compress yes all
tar yes all

The appropriate executables are in /usr/local/bin and that is reflected
in the ftpconversions file. And I am talking about a real user, not a guest
or anonymous user. Also, ckconfig reported ok and other features of
ftpaccess work appropriately.

2. The ftpconversions manual page is somewhat lacking. For example, I
had to look at the code to find out what T_REG and O_COMPRESS etc really
did. And the magic cookie of %s in the command field of the
ftpconversions file is not explained in the ftpconversions manual (I
assume it is for an sprintf type of call). Is there some better
documentation on this?

3. Some wuftpd's I have connected to have different version numbers.
Mine is 2.4(3). Others I have seen are 2.4(5) and 2.4(8). Where can I
get the most current sources.

4. And finally, is there an FAQ which I can access?

Many thanks,
Jim

Subject: Welcome messages...
Mime-Version: 1.0
Content-Type: text/plain; charset="us-ascii"
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

Hi all,

I seem to have a strange problem and I wonder if I have a misconfig somewhere...

The problem:

I do not allow anonymous login to my site (nothing to grap anyways<g>) I do
have several guestgroups. All works well exept that when a Guestgroup
"hits" the site it does not "count" .

I found that out following way: I have turned on messages on login and only
when a real user ftp's he/she will see the welcome message and it reports
user 1 out of x max. When a guest logs in it does display nil. So I turned
on the banner and even there is reports "You are user 0 out of x users
max."

Hmm, I then logged into my archive 15 time (10 times as guestgroup and 5
times as "real" user. The welcome messages I get as a real user reports
that there are currently 5 users logged in eventhough I know the real
number is 15...

Hope this makes sense and one of you might have a solution for me...

Thanks in advance:)

-Uwe

For usage by anonymous users make sure the binaries and libs and devices are
available under ~ftp.

For real users : there might be typos in the stock ftpconversions, since
some of the flags of some tar programs are a bit different. Check this.

I'd like to make a suggestion that would be very helpful to me and I think
alot of other ISP's.

I currently only allow FTP access to my accounts in order to allow them to
update their files. I do not provide Telnet. I like the Virtual FTP
because I saw it as a way to allow my accounts who have domain names, i.e.
abc.com, to setup anon FTP directories within their directory structure.
The only problem is that if they login using their real userid's, they get
set to the anon FTP directory that an anon ftp user would see.

Is there a way you can modify the code to check to see if the user logging
in is ftp/anonymous, and if not, check for the existence of a valid login id
in the /etc/passwd file and user the real user's HOME directory.

In other words, sai my userid is 'abc' and I have a domain called abd.com.
I would have setup abc's HOME directory as follows in the /etc/passwd file
as well as the master.passwd file:

abc:%TH(&FG:1001:30::ABC Account:/home/abc/./:/bin/csh

With this, and without using the Virtual FTP, the user would login as abc
and get dumped into /home/abc with this directory becoming their root directory.
This is how it works without the Virtual FTP set up. This user can now ftp
to ftp.abc.com, enter in abc as the userid and go to /home/abc and update
their files with their root directory actually being /home/abc..

Now, assume that abc.com wants to allow anon ftp to their site. So we setup
the ftpaccess file to allow virtual ftp. Now, when abc ftp's to ftp.abc.com
and enters in the userid of 'abc', they are now placed in the root directory
setup through ftpaccess, just like anon ftp would be.

What I would like to see is a check to see if the user logging in is a valid
user on the system and if so, placed in their HOME directory so that their
HOME directory is their new root and anon ftp placed in the root directory
setup in ftpaccess for virtual ftp. This would be a valuable addition to
the already much improved wu-ftpd.

Thanks,
Mark

Subject: Continued problems getting on-the-fly tar/compress to work
MIME-Version: 1.0
Content-Type: TEXT/PLAIN; charset=US-ASCII
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

This is a follow-up of the message I sent a couple of days ago. I
apologize for its length but I see no other way to get the info across. I
still can't get the conversions to work. In fact, one would think the
conversions are being ignored except that I have put debug statements in
to verify they are being parsed. My platform is a SPARC 5 running SunOS
4.1.4. I had no compilation problems and practically everything works as
advertised.

My conversion file is the one provided with the distribution. The only
difference is the location of the commands (mine are /usr/local/lib).

Here are the first two lines of my conversion file.

:.Z: : :/usr/local/bin/gzip -d -c %s:T_REG|T_ASCII:O_UNCOMPRESS:UNCOMPRESS
: : :.Z:/usr/local/bin/compress -c %s:T_REG:O_COMPRESS:COMPRESS

Since my ftpaccess file is short, I am including it here:

-------START OF FTPACCESS-------------

class everyone real,anonymous,guest *

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

readme README* login
readme README* cwd=*

message /usr/local/lib/ftpd/welcome.msg login
message /.msgs/welcome.msg login
message .message cwd=*

compress yes everyone
tar yes everyone

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

passwd-check rfc822 warn
shutdown /etc/shutmsg

email [email protected]

---------------END OF FTPACCESS---------------------------

The appropriate executables are in /usr/local/bin and
/home/ftp/usr/local/bin. Ckconfig reports okay. I am assuming that when
I issue the following command:

get foo foo.Z
or
get foo.Z foo

that compress or gzip is supposed to do its thing prior to tranferring the
file. I have tried various type negotiations but I still can't get this to
work for any user (real or otherwise).

I am compiling using gcc version 2.7.0. And the arguments to compress, gzip,
and tar have been verified to be correct.

Again, any help would be most appreciated.

Many thanks,
Jim

Hi James,
I too am in EXACTLY the same boat.
I too am on SunOS 4.1.4 with GCC 2.7...
My executables are in ~ftp/bin but aside from that all is the same...
I even tried changing my /usr/local/etc/ftpconversions file to call
a shell script 'test' that it never called... I did have to change
the ftpd.c code to enable compression..... on the following line
212
213 /* allowed on-the-fly file manipulations (compress, tar) */
214 int mangleopts = 1;
215
My default value for 'mangleopts' was 0, I changed it to 1

did you do that?

That still didn't help me... then I included ~ftp/usr/lib/ld.so
and libc.so.1.9.2*
and libdl.so.1.0*

in the hopes that this was that chroot problem mentioned... and that didn't
help so I then decided to build static versions of gtar ('tar') and gzip...
and mine still doesn't work either...

If you figure this thing out first... please let me know.

Here is my test script that I mentioned:
*** Begin ~ftp/bin/testi ***
#!/bin/csh
set date = `date`
echo "testi accessed: $date" > /dev/console
echo $date > /usr/local/etc/testi.date
*** end of ~ftp/bin/testi ***

*** Begin of /usr/local/etc/ftpconversions ***
:.Z: : :/bin/testi -d -c %s:T_REG|T_ASCII:O_UNCOMPRESS:UNCOMPRESS
: : :.Z:/bin/testi -c %s:T_REG:O_COMPRESS:COMPRESS
:.gz: : :/bin/testi -cd %s:T_REG|T_ASCII:O_UNCOMPRESS:GUNZIP
: : :.gz:/bin/testi -9 -c %s:T_REG:O_COMPRESS:GZIP
: : :.tar:/bin/testi -c -f - %s:T_REG|T_DIR:O_TAR:TAR
: : :.tar.Z:/bin/testi -c -Z -f - %s:T_REG|T_DIR:O_COMPRESS|O_TAR:TAR+COMPRE
SS
: : :.tar.gz:/bin/testi -c -z -f - %s:T_REG|T_DIR:O_COMPRESS|O_TAR:TAR+GZIP
*** Endo of /usr/local/etc/ftpconversions ***

I have since also tried the original ftpconversions (in the wu-ftpd example
directory... and it didn't work either)... I don't think it's even accessing
any of the commands in /usr/local/etc/ftpconversions... because my
testi never ran.

Well, no, actually. That only does filename conversion in the FTP client
(for 'get foo foo.Z' the client gets foo and saves it on disk as foo.Z) (or
at least standard Unix FTP clients work this way). You need to `get foo' if
you have foo.Z in the FTP directory, or `get foo.Z' if you have foo and want
it compressed.

Well, that was the problem. Things work as advertised. I guess I
just had it in my mind to specify both names as a trigger to do
the conversions. Having read the man page several times it still
didn't occur to me to specify a file which "wasn't there."

Thanks,
Jim
