Subject: Restrict put capacities only for local users.
Mime-Version: 1.0
Content-Type: text/plain; charset="us-ascii"
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

I have two classes of anonymous users, the locals users that match my
domain, and the remote users that doesn't match my domain. I want to
restrict put capacities ONLY for LOCAL users, is it possible?

This is some lines of my /etc/ftpaccess:

-
class local anonymous *.foo.bar 0.0.0.0
class remote anonymous *
..
limit local 25 Any /etc/msgs/msg.toomany
limit remote 10 Any /etc/msgs/msg.toomany
..
upload /home/ftp /incoming yes ftp daemon 0600 nodirs
..
-

Thanks in advance.

Hi I've

made two little changes to the 2.4.2-B15.

1. I've added the keyword ,,chdir <yes|no> <typelist>''.
f.e if you like to have some guest or. distribution accounts that
have access to one directory only.

2. I've added the keyword ,,system'' as an upload root-dir.
f.e. with the following line in the ftpaccess you can deny
any upload into the /tmp dir also for real users.

upload system /tmp* no nodirs

Ciao Thorsten

Put a line in ftpaccess like

upload /ftp_root_path /incoming yes root daemon 0400 nodirs

That way they cannot create directories and cannot read back or
overwrite any uploaded files. If you can still create directories,
something may be wrong with the daemon.

Set /incoming to 0733, owned by root.daemon or some other non
anonymous user.group. That way they can create files but cannot read
the contents of the directory back.

Now that RFC 2228 was published in October 1997 my managers are starting
to ask about it. Dont remember reading any discussion in the mailing
list about it? So what are people thoughts, should WUFTPD be enhanced to
support these FTP security extensions?

Hi

I had problems seeing the owner and group names in "dir"-command.

Thanks to Jim Davis:

actually it's 2.6

He's right.

And the best is, there's a shell script at the end of that man page
which makes the directory setup for bin, dev, etc and usr.
Because I'm not sure about legal rights, I don't post it here. But it
worked for me after repairing one line:

orig: ftplib="`echo $ftplib | tr ' ' '0 | sort | uniq`"
new : ftplib="`echo $ftplib | tr '^M' ' ' | sort | uniq`"

the ^M is a ctrl-M.

Cheers, Roland.

John,
I got hit by them on Thanksgiving myself. The line that took care
of it for me (I think and hope) was...
upload /public/ftp /incoming yes ftp other 0640 nodirs

Our FTP site is primarily for local use, so I also defined "local"
and "remote" classes (set via IP address) and limited remote connections
to 5. If nothing else, this will slow down their progress if they should
get back in.

I thought I had followed the setup instructions pretty closely, but
if I did and this wasn't in it I'd like to see this added. BTW--Major
THANKS to the setup contributors! If Sun's docs were only half this
good....

later,
-greg

Subject: How to deal with WareZ?
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

How do I figure out whether a record in xferlog is GET or PUT?
The following lines are the beginning of my latest WareZ episode.
I'm using DOMAIN1 and DOMAIN hide the real domains. What are the
typical procedures people take when it happens? Should I contact
the domains' administrators? I assume the attackers are not
the administrators considering they used dialup accounts.
My server was bogged down for several days. I don't want to
punish them too harsh considering they might be a few kids.
But I'm angry.

John

The 'i' after the '_' would indicate that the file was incoming. An
'o' in place of the 'i' would represent a file sent from the server to the
client; ie and outgoing file.

This doesn't directly relate to wu-ftpd but since the members are knowledgeable
ftp'ers here goes my question:

I want to ftp a file to a remote site where a program will automatically
process it once it's transferred. What are the different ways that the
remote program can know that the transfer is complete ? (I obviously don't want
the program to pick up the file in the midst of the transfer)

Thank you

Hi,

I still have the same problems seeing the owner and group names.

I followed all the instructions on Sun's in.ftpd man page and also tried
the script at the end of the man page. But it doesn't work. I only see
UID and GID numbers using the 'dir' command.

The version 2.5.1 doesn't have this line.
Any hints for Solaris 2.5.1?

Thanks, Martin

You should use FileDrive EX. It hass all the wu-ftpd features
plus security and *Active Agents*. Active Agents lets you
define automated actions to run on files. You can define them
to run at start of transfer, failure of transfer, or completed file transfer.

wu-ftpd does not have this capability. It doesn't know when a file
has completed transferring.

When we built our FIleDrive SX and EX servers (partially based on wu-ftpd)
we tried to deal with this Warez problem. I got hacked late last
year by some naughty warez kiddies. SO what we did is:
1- Web-based admin system so you can configure these things more easily.
2- Security auditing system that can alert you to new dirs and files
that get uploaded. We also added some treats that scan the
file types looking for things that could be OS patches. There
are some nasty vulnerabilities in UNIX that can let folks
who can upload really clobber you ....

3- upload perms are on a per user basis, *not* per directory as in wu.

If you wanna know more, just call. :-)

Is there any security reason to not use /bin/passwd for a shell for a
chroot, guest user so they can change their password anytime they want?

here is the /etc/passwd entry that I'm talking about to be clear:

focus:123432:101:101:Focus Comics:/usr/ftpusers/focus/./:/bin/passwd

or am I opening myself up wide open?

Also, is virtual anonymous available (ie: I can do anonymous for focus
and anonymous for furph.com and they will goto two different directories?)

thanks

How can I correct this ? Is there a patch for wu-ftpd or linux ?

Another question, is it possible to make a two differents type of guest

can ?

I have followed the HOW to for creating a guest account that does a chroot
for a ftp user. The chroot works but ls does not return any file names.
If a filename is known it can be retrieved, just not seen.. Any help
would be great.

The manpage misses libmp.so*, unfortunately. So try copying
/usr/lib/libmp.so.* to your ftp library directory and see if that fixes
it.

The procedure to set up an external 'ls' is covered in the guest
howto. OS specific tips are toward the end of the doc. You probably
have a dynamically linked ls installed without the necessary support
libs/devices. Go over the guest howto again and pay attention to
every detail.

This is now the second or third time you have done this. IMO you are
out of line promoting your product here. This is a support list for
wu-ftpd, not a forum for you to be pitching your warez. The quality
and/or utility of your product is irrelevant to the charter of this

I couldn't agree more. If this activity of pickup up "leads" off
of this list continues, people will avoid using a list for support,
sharing of knowledge due to the high incident of "sales calls".

I have the same set up. Logging goes to /var/log/xferlog. This is set at
compile time, check out _PATH_XFERLOG in src/pathnames.h and
USE_VAR and USE_LOG in src/config.h .

Sure. I guess I figured that since I do post answers to many
questions on a frequent basis, and because our product is
the only professionally supported wu-ftpd-compatible in the world,
that maybe occaisionally someone might want to hear about
it.

We've got people who've spent more than 1 year each of their lives
living inside the wu code on a daily basis, so we're pretty qualified
to answer questions about it.

Generally, if I err and mention our product, it is because it support
a feature that someone on the list asks for, but that isn't
available in wu.

I'll be quiet now.

It appears that Macintosh users with Netscape are unable to establish a
socket connection with the ftp site. The Fetch FTP client works fine from
the Mac -- it seems to be just Netscape.
Netscape works fine from Windows 95.
Mac/America Online getting the error message "This FTP site does not
support Passive Mode"

Does any one have a fix for this?

We are running 2.1.7.1-RELEASE FreeBSD 2.1.7.1-RELEASE with Version
wu-2.4.2-academ[BETA-13}.

Our problem is that anonymous users connections appear to stay open a long
time even after they have finished there download. A ps -aux | grep ftpd
shows users from a month ago ?

Will a new version of the software fix this problem or is it a config issue
? If its new software can I simply compile the ftpd and still use my old
config files.

Unfortunately you neglect to say what your OS is, so this _may_ not apply to
you... However, if you're running on a Solaris 2 box, you need to make sure
that ~ftp/dev/tcp has write permissions set for the world. This is
documented in the FAQ available at
http://www.hvu.nl/~koos/wu-ftpd-faq.html
or via Kent Landfords's WU-FTPD Resource Center at
http://www.landfield.com/wu-ftpd/

Hope this helps...

Cheers, Bob

I did the following:

/etc/passwd has:
bikes:23232:1006:1006::/usr/local/wwwsites/www.bikesonthenet.com/./:/bin/false

/etc/group has:

~bikes/etc/group:

root:*:0:root
bikes:*:1006:bikes,larryl

Copy from /etc/sia dir to ~bikes/etc/sia the files matrix.conf and
siainitgood like the faq said.

ftpaccess has guestgroup bikes

I know the ftpaccess file is getting read from inetd.conf since other
stuff from it is happening (like noretrieve passwd). bikes can log in
just fine, but the chroot is just not
happening. I also tried changing the passwd entry to be like
/usr/local/wwwsites/www.bikesonthenet.com/./htdocs and that didn't help,
bikes could just login into /usr/local/wwwsites/www.bikesonthenet.com.
does anyone else have wu running under Digital unix 4.0 without c2?

I don't remember seeing answers from you regarding specific help with
wu-ftpd. I read much mail quickly, so maybe I missed it. So, I went
to the archives for this mailing list and queried on "Jevans", also on
"differential". The results on both are below.

Sorry... NO Matches were found for query

I don't know what the lag time is between the list and the archives.

What I have seen in the last few days is a rapid escalation in direct
solicitation for your product, where none has been here before.

Feel free to do just that. Any contributions you have to make to
wu-ftpd are welcome. Promotions, thinly disguised or blatant, of your
own commercially competing product are not.

I'm not the list mom. I do have a long standing track record of years
with this list, as do others who have given more than I have. I know
the culture of this list, and your commercials are new and unwelcome,
to me at least.

No, what you have done is advertise features that yours has in
response to help requests about wu-ftpd. It isn't just that people
have asked about specific features that yours has. The "answers" you
have posted have contained no directly helpful information to get them
going with wu-ftpd and thus are off charter.

Which complier are you using. I have Solaris 2.4 with gcc version 2.7.2
and ftpd-2.4.2-beta-15 compile without a hitch.

A long known problem. I think beta 15 clears up a few more of these
hangs. Jon Lewis posted something to the list recently that clears up
most/all of them; the list archives will have it.

Here's one method that works pretty well:

1) Ensure that you have a distinct log message (syslog or tranfer log) when
the
transfer is completed successfully. That's your trigger. You may need to
add log messages to the code for this.

2) Get swatch. It's log watching program that looks for user-specified
patterns
in a log file, and executes a user-specified command when such a pattern
appears. It's very useful for ordinary sysadm work. You'll need perl to
run it.

3) Set up swatch to watch the logfile where the trigger message appears, and
set up a pattern:action rule for that particular transfer.

As you hace access to perl pattern matching, you can set up rather complex
matches.

Also, this will start the action as soon as the log message appears.
If you don't need that quick response, you can also feed swatch the logs
that have been collected since last time, and so run the necessary actions
at a time that you decide.

If you'd rather not use perl, it's not too difficult to write a small C
program that does much the same thing by using the regexp package.

hope this helps,

This is the right hint, thank you.

Additionally, the entries in ~ftp/etc/passwd must have the right number
of ':', e. g.

root:*:0:1:::

Otherwise (if the concluding ':::' are missing) the entry is taken
from NIS passwd.

Most people are human and understand such things. On top you can allways
control what information you give out. It should be in every sysadmin's
interest not to have his users do stupid stuff, because in the end it
might be himself who's the victim. So I would call the admin and talk and
see...

Has anyone tried to implement a threaded verson of the server?
This would have much performance benefit. However, it seems
to have many challenges as far as user IDs go (ie. setuid
an chrooting). Also global state variables would appear
to be a real mess. Ideas? Progress to report?

WRT: searching the archives.
Searching the wu-ftpd list archives by user name *doesn't work*.
eg. a search for mbrennen reveals: NO Matches were found.
However, browsing the archives shows that there are numerous
posts from him and others..... hmmmm.

I recently installed a copy of WU-ftpd from
ftp://opcom.sun.ca/pub/freeware - they have a collection of pre-compiled
packages of UNIX freeware for Solaris there.

Well, before multi-thread, having a stand alone version should
come first. I looked into the code lately, the configuration
files are read for every command. For a stand-alone server,
the configuration can be loaded into the memory at startup.

Ftp it to a different file name, then rename it to the expected file name as
a second ftp command. Then as soon as the file exists (under the expected
name), it's complete.
Renames in unix are atomic.

Does anyone know of ports of a recent wuftpd to Windows NT or VMS?
We're looking at using the server as the basis for a distributed file
transfer system and need an ftp daemon for NT and VMS which gives us
the ability to use "site exec". We're also thinking of implementing the
IETF's machine readable directory information draft standard so source
availability is pretty important. Quick searches for free (with source)
ftp daemon's for either OS hasn't turned anything up. Right now,
porting wuftpd is looking like the simplest option.

Related to this, is anyone working on adding the IETF extensions to
wu-ftpd?

Thanks in advance,

-Mark.

I did this exact search last night before posting my response about
'Jevans'. A search on 'mbrennen' in the wu-ftpd mailing list archive
shows:

We have been running wu-ftpd on a BSDI system and recently upgraded to
wu-ftpd-2.4.2-beta-15. Since that time, only ftp connections are
logged; commands are not. I saved the old ftpd before installing the
new one, and if I switch back to it, logging of commands starts up
again.

Any help or suggestions on how to get logging working properly would be
greatly appreciated.

Thanks in advance,

I just tried it myself and it worked. It may have been that you tried
it during the "exact time" the newly rebuilt index was being renamed
but I thought I had that covered with a "Index rebuild in progress"
condition... :-) Maybe not. I'll check again.

Please, if you run across something on the Resource Center that is strange,
out of place, missing or needed drop me a note. I'm always looking at
ways to improve it and make it more useful.

Also remember that if you have wu-ftpd extensions you'd like to see added
leave a suggestion in the suggestion section or the Resource Center. Tracking
suggestions from there will be a lot easier than trying to 'mine' the
mailing list archives... ;)

Hmmm. I thought someone did a patch for this already?
We did this in FileDrive and it improves performance *dramatically*.
Watch out though, if the config files change, be sure
to reread them before forking.

This doesn't deal with the crux of the issue, however, which
is determining if the file is completely there before processing,
or renaming. wu-ftpd doesn't know if the file is completely there.

Remember also that sometimes file transfers aren't successful
and you get only part of the file. WU logs these as completed
transfers. The challenge is to figure out if you got the whole file.
This is difficult, because the FTP protocol doesn't specify file
sizes before sending, and it has no way to ACK that the file was delivered
in its entirety.

We've been working on extensions that involve crypto signatures to verify
that files are completely delivered (even if it takes multiple resends).

If anyone has done similar work I'd love to talk.

Hmmm. I thought someone did a patch for this already?
We did this in FileDrive and it improves performance *dramatically*.
Watch out though, if the config files change, be sure
to reread them before forking.

I looked through the wu code a few months ago.. with plans to thread it.
After spending a couple hours, it became apparent that it would be easier
to start from scratch. Especially if you want to maintain regular unix
type user logins, as you mentioned. Since from what ive tested, wuftpd
starts dieing at around 2k logins (not necessarily xfers in progress)..
a site with that many logins is going to be mostly anonymous. If not,
they probably have more than 1 machine doing it anyway.. and 2k per
machine is decent.... In the end i had to end up writing my own.

Besides, doing the security on it for regular user type logins wouldnt be
trivial... compared to chroot() anyway. Even though its per process, and
its not perfect.. its alot easier then keeping that state info.

That is true, i couldnt think of a defacto way to figure out if a upload
was completed fully and successfully. But, you can usually beware of a few
things. One is, were there any errors? If there were read() type errors or
something similar, you can be pretty sure the file was not complete. And
ofcourse.. if it was cancled midway through. Altho this wouldnt be a
perfect fix.. id bet it would catch more than half of incomplete xfers. :)

I hope this is the right place for questions like this, if not, i would
appreciate it if you could point me in the right direction.

I'm trying to install the washington university ftp daemon on a sunsparc
10 under solaris 2.5 for an anonymous ftp site. Because of disk space
limitation, I'm running into some trouble getting it properly installed.
The ftp site wants to be in /var/spool/ftp. However, there is not enough
room for it in the /var partition. I tried to mount the /var/spool/ftp
directory on a separate partition. When i do this the anonymous ftp site
can not read any directory info or file info. It gives the following
error:

****
230 Guest login ok, access restrictions apply.
ftp> ls
200 PORT command successful.
425 Can't create data socket (0.0.0.0,20): Bad file number.
ftp>
****

The ftp site still works for people who log in with their login names,
just not anonymous users.

It also works correctly if i install it in the /var partition, but there
isn't enough room for our public ftp files. Does anyone know how to get
around or fix this problem????

Yep. Thats what we do if you are using a regular FTP client.
Check for broken pipes, ABORT commands, etc. This does get
many of the incompleted xfers. If the server talks to a client
that supports our extensions, then we enable the more reliable
message checksumming to determine if the file is completely
uploaded.

This is very important if you are using FTP to implement things
like EDI or EFT or various kinds or remote document processing.
In those cases it become pretty critical to know if the
file is completely there before triggering a processing stage.

The problem is that the silly FTP protocol relies on a
read() returning 0 bytes to indicate the end of a file transfer.
There are many failure conditions that look like this. :-(

You definitely do not need to use /var/spool/ftp. You can
use any directory (partition).

But your problem seems to be a network problem, firewall
or host blocking of PORT.

Done. Take a look a

Lee McLoughlin ([email protected]) has made some nice changes that should be
a part of the baselined wu-ftpd.

After copying the appropriate libraries, the owner/group names are still
not shown. Is this working for anyone else on a Solaris 2.6 box? (I'm
running 2.4.2.-b15). Thanks!

Sounds an awful lot like the static vs dynamic "ls" problem
described in the FAQ. See "http://www.landfield.com"

It'll describe how to fix the problem. BTW--Be sure to
get the latest version (beta15).

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

This is the one I used. I searched it with lynx 2.6. I don't know of
another archive site.

To all on the list: please understand that I in no way am disparaging
the product that Mr. Jevans is presenting. It may be very good, very
useful; I've not looked at it. I just don't think this is the place
to promote it. Many different lists I have been on have slid rapidly
when competing commercial posts started, and I have no wish to see
that happen to this list.

I wrote earlier today about having problems setting up an anonymous wu-ftp
site. Thank you for all the replies i have received. The problem turned
out to be something very simply and basic. The answers i received helped
point me in the right direction. The problem was the partition we intended
to use, had "nosuid" flag set. I thought i had checked this earlier, but
it somehow slipped past both the system administrator and myself.

Once again, thank you for the replies, you definately helped us to figure
out what the problem was.

Yes. We run b15 on Solaris 2.6. I had to just break down and build a
static ls and it works fine now. The time it took to get everything
together (gnu sources and the static patch) and make the static ls
compared to the time I spent working on it previously made me wish I had
just made the static ls at the begining.

So, if you are looking for an opinion of what to do on Solaris 2.6...my
vote goes to just throwing in the towel and building a new ls.

Try to use '-L' option while starting ftpd daemon. But this
option is overridden by "log commands" directive in ftpaccess
file. So check this file also.

Hope this will help you.

Hi,

I've had the same problem, working with nis.
Changing the permission in dev/ directory, now it works:

ll dev
total 4
2 d--x--x--x 2 root sys 512 Nov 28 12:34 ./
2 drwxr-xr-x 7 root sys 512 Dec 2 10:57 ../
0 crw-rw-rw- 1 root sys 13, 2 Nov 28 12:07 null
0 crw-rw-rw- 1 root sys 11, 42 Nov 28 11:34 tcp
0 crw-rw-rw- 1 root sys 105, 1 Nov 28 11:34 ticotsord
0 crw-rw-rw- 1 root sys 11, 41 Nov 28 11:34 udp
0 crw-rw-rw- 1 root sys 13, 12 Nov 28 11:34 zero

try putting write permission for other.

Hi everybody,

I am setting up an anonymous FTP server for solaris 2.5.1
(wu-ftpd-2.4.2-beta-15) and since different sources of information give
different and sometimes contradictory pieces of advice, I would like to ask
you a few questions :

- the server seems to work fine with only /dev/tcp, but I've read that
/dev/ticotsord, /dev/udp and /dev/zero are also required. Can someone tell
me what for ? Note that I'm using a statically linked ls, if that matters.
- should the device(s) have permissions 666 or 644 (they are owned by root)
?

- NO upload is allowed on this server. In this case, does the user "ftp"
have to own any file in the server directory tree ? (it seems to work fine
without).

- In this case (no anonymous upload), is it worth considering putting the
FTP server itself in a chrooted environment as it is suggested in the
Anonymous FTP FAQ ? What extra security would it provide ? Note that there
is no binary in the server directory tree apart from "ls".

Last question : would it make a difference on Solaris 2.6 ?

Thanks in advance,

Arnaud Ruch

Sorry, I forgot one question :

- are netconfig and nsswitch.conf required in etc with a static ls and no
use of NIS ?

Thx

Now that RFC 2228 was published in October 1997 my managers are starting
to ask about it. Dont remember reading any discussion in the mailing
list about it? So what are people thoughts, should WUFTPD be enhanced to
support these FTP security extensions? Has any work already been done
in this area?
Thanx,

# Now that RFC 2228 was published in October 1997 my managers are starting
# to ask about it. Dont remember reading any discussion in the mailing

# support these FTP security extensions? Has any work already been done
# in this area?

Cygnus did an implementation of the GSSAPI mechanism as a part of their
KerbNet product, which you can get free from
http://www.cygnus.com/product/kerbnet-index.html. This code has also
been integrated into MIT's krb5 tree. There are several other
implementations, but none are free. I am currently looking at what it
would take to integrate what was done there with wu-ftpd.

Now the problem... The FTP Protocol is in the process of changing and
potentially drastically. Yes it will be backwards compatible with the
current RFC 959 but beyond that...

There is a great deal of work that is ongoing with the IETF FTPEXT working
group. These efforts include

* FTP Security Considerations
* FTP Extensions for Variable Protocol Specification
* Internationalization of the File Transfer Protocol
* Feature negotiation mechanism for the File Transfer Protocol
* Extended Directory Listing and Restart Mechanism for FTP

For more information on this see http://w3.hethmon.com/ftpext/

[ Stepping up on to the soapbox and grabbing the microphone... ]

I have some serious concerns about the way the community is approaching this
area. There seems to be multiple camps producing FTP related works that are
not communicating with the others. Because of that we are seeing the begining
of splintering of FTP capabilities. Something needs to happen or we may see
the end of a "Fully" functional FTPD that is available in source form.

What do I mean ? If there is not an effort, in much the same light as the
appache or linux folks, to incorporate these new features then the only
version of FTPD that you will want to run in a production network is one
you have to pay bucks for. The free versions will not have the neat and nifty
features that management sees as a checklist item. I'm sick of that approach.

Wu-ftpd was developed to better the foundation of the net (NSF grant funded
development). Because of that we have all benefited. What would it be like
for the smaller sites if there wasn't an effort such as Apache and you had to
buy your web server, your mailers, your ftp client and server software, your
PC operating systems, etc. ?

I propose we need to address this on this list soon or watch the wu-ftpd
become just a footnote in Internet history.

[ Stepping down to see the crowds reaction and take my licks. ]

Thoughts ?

Short question.

Has anyone tried to compile wu-ftpd under RedHat 5.0 now that its using
glibc? I tried but got numerous errors (unfortunately I didn't save them

at the time). To solve the problem I went back to redhat 4.2 and the
conventional libc and beta 15 compiled no problems.

Since wu-ftp still comes with RedHat 5.0 I assume there must be some way

of compiling it......maybe some switches or something. I'm considering
returning to RedHat 5 but really need to get an answer to this question
first.

Thanks

leaving out /dev/ticotsord crashes Solaris versions before 2.6 if a
chrooted program tries to obtain a lock on an nfs mounted file system.

You'll need /dev/udp for NFS if any server does not accept NFS
protocol vers 3 (or you configured the mount to use version 2), as
well as for NIS, if you need that.

> - NO upload is allowed on this server. In this case, does the user "ftp"

User ftp never needs to own any files, even in upload areas. It just
needs write access in the latter case, but it doesn't matter by what
rules (a+w, acls) it gets it.

If you create a directory tree for ~ftp, you'll get the chrooted
environment automatically. If you set ~ftp to / (even then a
chroot("/") will be done, but you'll need spmething like lsof to
detect it), your whole directory tree will be visible, and I wouldn't
bet that wu-ftpd (or any other program) wouldn't contain some funny
bug somewhere.

> Last question : would it make a difference on Solaris 2.6 ?

I haven't yet tried it, but at least wrt /dev/ticotsord there should
be one.

> use of NIS ?

netconfig: yes
nsswitch.conf: I'm not sure if wu-ftpd makes any gethostby...() calls
after the chroot(). If so, you'll need it just to enable dns lookups.
All other entries should just contain ``files''.

I have wu-ftpd-2.4 running on a Solaris 2.5.1 machine and have not
been able to get the "ls" command to work properly when I ftp in.
"ls" by itself will return a listing of files - no attributes.
"ls -l" will pause for a while and return NO listing of files.
Strange thing is, if I ftp in from a completely different domain -
the "ls" command will return NO listing of files.

Any help in pointing me in the right direction is greatly
appreciated!

The external 'ls' is not working properly. The guest howto and FAQ

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

Subject: passive mode and firewalls
MIME-Version: 1.0
Content-Type: TEXT/plain; CHARSET=US-ASCII
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

While recently setting up a firewall I learned about passive mode for
ftp. It wasn't a happy finding as it would be preferable to keep ftp
services contained to the normal ftp and ftp-data ports.

If passive mode is disabled in the server will most (or all) popular ftp
clients and web browsers revert to using normal mode if an error message
is sent in response to the PASV command?

Is there any way of using ftpaccess to disable the PASV command with
wu-ftpd-2.4.2-beta-15 and if not might this be added in the near future?

Thanks!

This is a commonly hit upon 'feature' of the ftp protocol. I believe
we had this discussion a while back, and I know that there are at least
two patches floating around (check archives) for restricting the range
of ports that PASV connections will use. In this way you can restrict
the ports to say 32000-32999 and open your firewall for those ports
only; saving you the hassle of a completely open policy.

I found that and tried one of the patches. There are two problems:

1) I would still prefer no PASV at all if that is practical. I have
one report from email not related to this list that says you can return
the following and all clients (including Netscape) would revert back to
normal transers:

reply(525, "Can't open passive connection: Undefined error: 0.");

His patch returns this from the top of passive() and then returns from
the function.

2) The port range limiting patch I tried didn't work:

Dec 5 10:08:07 falcon in.ftpd.pasv[10110]: connect from [email protected]

Dec 5 10:11:42 falcon ftpd[10110]: RETR memtest86-1.1.lsm

Note that in each case the patch reports using one port yet connections
show up on an other. I have no idea why this is.

If disabling PASV isn't a reasonable plan of action then I would like
to at least get port limiting to work.

Thanks!

What architecture are you using? When assigning ports to the in_addr
structure you must use htons(portnum) because the TCP/IP specs mandate
this bit order in the structure. I've hit this before when taking code
from a sparc and placing it onto an x86 architecture which has a different
byte order. :)

My only problem was netscrape seemed to mandate it; but if returning
that error makes it resort back to regular mode, I'd be willing to
disable PASV mode! :)

I have setup WU-FTPD Beta 15 and it seems to be working great on my
BSDI
box. I have setup about 5 virtual domains and so far so good. The
question that I have is this. Is there anyway to have WU-FTPD use a
different passwd file??? I would like to have my virtual domains to be

totally separate.

If this is possible, is it secure???

Plus, if it is not available, does anyone know when it might be?

Thanks

# I have setup WU-FTPD Beta 15 and it seems to be working great on my BSDI
# box. I have setup about 5 virtual domains and so far so good. The
# question that I have is this. Is there anyway to have WU-FTPD use a
# different passwd file??? I would like to have my virtual domains to be
# totally separate.
#
# If this is possible, is it secure???
#
# Plus, if it is not available, does anyone know when it might be?

It is not currently possible but work is on-going with the newvirt-040
version of virtual domain support. (http://www.landfield.com/wu-ftpd/newvirt)
I are hoping to have it integrated shortly. (Hopefully within the next week.)

What I'm doing is wrappering the getpwnam(), endpwent(), getgrnam(),
endgrent() and the getgroups() functions. If you are using virtual_mode
and an alternate passwd/and or group file exists in that domains config
directory then it is used instead of the system one.

There is a problem here that can be easily dealt with via policy (and maybe
via software but I haven't figured that out yet unless I just forbid it).

The problem is uid/gids. If you have a virtual domain, the user and group
ids used in the alternate password file better either not exist in the system
passwd or group file or match the same user or group. You would not want to
this virtual domain software to create a new way to do group sharing... ;)
If you could allocate a block of UIDs and GIDs to a single domain ...

As always I'm open to suggestions.

You can find out exactly what RedHat did to build wu-ftp. This is one of
the great things about RPMs.

Install the source RPM:

ftp://ftp.redhat.com/pub/redhat-5.0/SRPMS/wu-ftp*

Then look in /usr/src/redhat/SOURCES and /usr/src/redhat/SPECS/wu* for
patches and the build process.

Sounds great. I look forward to installing it. I am using BSDI 3.1, so I will
let you know if I have any problems on that platform.

In regards to the UID/GID issue, I am not a UNIX expert so forgive me if this
doesn't make sense. What I am trying to accomplish is that I want to have many
virtual domains on my system. I want each one to be able to have their own FTP
account and POP3 accounts. I would like to allow them to add FTP/POP3 accounts
on their own. And that these would stay only in their password file. This would
allow each domain name to have say a username of george. Plus it would prevent
someone from using a username and password that works on one domain and use it
with another domain on my system. Since this password file is not the "real"
password file, couldn't each of the usernames have the same UID/GID in the domain
password file???

Are you going to post a message in this message group when the new version is
done??? I am willing to test it for you on BSDI 3.1...

Thanks

I was wondering if any of the developers were looking at implementing
LDAP authentication in future versions of Wu-ftpd. I am currently
investigating the possibility of such a venture.

# Sounds great. I look forward to installing it. I am using BSDI 3.1, so I will
# let you know if I have any problems on that platform.

Thanks. I'll take you up on that. ;)

# In regards to the UID/GID issue, I am not a UNIX expert so forgive me if this
# doesn't make sense. What I am trying to accomplish is that I want to have many
# virtual domains on my system. I want each one to be able to have their own FTP
# account and POP3 accounts. I would like to allow them to add FTP/POP3 accounts
# on their own. And that these would stay only in their password file. This would
# allow each domain name to have say a username of george. Plus it would prevent
# someone from using a username and password that works on one domain and use it
# with another domain on my system.

Hmm. I can't help you with the pop3 stuff. Their configuration would need to be
altered to support this. You could have different george accounts but the uid and
gid should not be the same. If they were then one george could possibly overwrite
another's file if their uid was the same.

# Since this password file is not the "real"
# password file, couldn't each of the usernames have the same UID/GID in the domain
# password file???

>From ftp's perspective, the accounts will be real but separated. The system will
use the uids and gids as if they were real.

# Are you going to post a message in this message group when the new version is
# done??? I am willing to test it for you on BSDI 3.1...

Yes, I will post a message when it is available. The first few sites will need to
be very brave. ;) This will definitely need to be looked at by others before I'll
feel comfortable.

but if you set upload permissions on the anonymous directory to be not
executable, would that help? If I can't use gtar to make a static tar,
what can I use (under Digital Unix 4.0)?

thanks

Subject: Weird Bug In 2.4.2b11-11??
In-Reply-To: <[email protected]>
MIME-Version: 1.0
Content-Type: TEXT/PLAIN; charset=US-ASCII

I've just set up guest FTP on a RedHat Linux box, using wu-ftp
2.4.2b11-11. The set up went well, and guest FTP worked exactly as
advertised re: chroot, restricted cd, and so forth.

However, once this was set up, regular FTP user could no longer
successfully execute /bin/ls on their home directories, nor could they cd
above them! They could, however, put and get files.

I had only changed 3 things in /etc/ftpaccess from it's default settings:

1) allowing overwrite permissions to guests and anonymous

2) adding the line:

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

3) adding the line:

"guestgroup ftponly"

Eliminating these 3 lines from /etc/ftpaccess returns FTP access for real
users back to normal, but also allows guest users to cd out of their
assigned directories.

Is this a bug in 11-11 which requires an upgrade, or am I getting
something totally goofed up here? Any pointers would be greatly
appreciated...

TIA,

--Duncan

Here's the full listing of my /etc/ftpaccess:

I would love to be one of those first few sites. This will help out hosting companies
greatly and I really appreciate the effort you are putting into this.

Implementing PAM would require total rewrites to the user authentication
section to accomadate it. This is not something that I have time for at
the present time. I do have time for the wrapper extensions as there are
so few places that I have to replace calls and so little code to write.

PAM is a good idea. This is exactly the type of thing I was talking about
the other day when I said things need to start moving faster. I'd really
like to see it done but I have a problem to solve. And from the non-reaction
I received from my rant it doesn't look as if I'm going to get much help.
So I'll do it this way for now. If I'm the only one using it, so be it.
When people find time to think about doing it right we'll probably find a
near total code reorg is in order.

If this sounds bad I apologize. It was not meant to. It's been a long day and
I nearly have the wrappers done...

I must have missed your original posting. I agree with you that WU needs a
serious looking to. Something on the order of what Apache did to NCSA.
And I would really like to help in this work. The problem is I have no
spare time. I'm behind in my regular work schedule and probably won't have
any spare time until next spring. I was hoping to use WU in one of my
current projects. That way I could be paid to put some work in. I decided
to go with HTTP and NPH-CGI instead.

My highly personal wish-list:
Better config file format
Better error logging. (If ls or zip won't work, I need an error as to why,
damn it! And trafic on this list would plummet! -:)
Common log format (ie access_log) log files would be cool

Things that would be useful:
Stand-alone server w/ threading
PAM
Expansion module capability

While we're dreaming, why not:
CGI-like capabilities (get a file, said-file is executed, output is
transmited. The problem now is, how do you transfer the file contents, not
it's output? -:)
transfer-triggered execution (transfer a file too/from a directory, trigger
external program before and/or after)
ftaccess files, operating like .htaccess

As I see it, we first need the new config files and a stand-alone server.
Then we could write the expansion module stuff. Stand-alone server comes
first because parsing the config files and loading the expansion modules at
each invocation would be a bad performance hit. After that, we can run
wild with writing modules.

Then again, could one write an FTP module for Apache and leverage their
code-base? Or even just grab Apache, gut out all the HTTP stuff and use it
as a squeleton? (Remember, I'm in dream-on mode -:)

I have yet to really look at the source code. I have no idea what state
it's in nor how much work or reworking it would take to get any of this
done. Provoked by an article in Linux Journal, I've thought about PAM a
bit. One complication I see is the chrooting business and how it would
relate to pam_open_session(1). In fact we might have to write a PAM module
to take care of guest users, anonymous users and the "virtual" users you're
working on.

Hey, no worries. I've had a bad week too. I find a St-Ambroise Oatmeal
Stout helps.

Hey guys! Wu-ftpd already works with PAM. That is exactly what Redhat
ships on their CD and is available at their ftp site. The pam module
doesn't provide support for virtual domains but it is there and it does
work. ...works quite well in fact.

Subject: On the future development of wu-ftpd
X-Listprocessor-Version: 8.0 -- ListProcessor(tm) by CREN

It is certainly my intention to continue to support wu-ftpd as my time
permits, but perhaps that is just too slow a pace for many of you who want to
see a number of new features added before all the bugs are stomped. My desire
is to stomp the bugs in the current server before we rip it apart to add new
features. The two goals work against each other with the way the current
server is constructed.

It is my plan to work towards a release of 2.4.2 followed by an
autoconfiguration version of the same server which I will call 2.4.3.

After that, I had planned to significantly change the server in many of the
ways the apache team overhauled the NCSA server. At that point, I was going
to suggest that a project like apache be organized to provide modules for
that new server that might implement some of the features folks want. That
future (in my time line) was to start next year in the summer. The first
release was to be a new basic server that would be compliant with the FTPEXT
documents and would have a new API through which folks to build modules to
hook in new features. This server would not implement everything in wu-ftpd
at the first release, but would build up features on a module-by-module
basis. At that point, my job would be to maintain the basic server and
perhaps house a module repository (with appropriate mirror sites) and look
to others to build and maintain modules. The biggest help to me in making
that happen would be to define the API as well as the basic feature set for
the basic server.

For those of you who can't wait for those developments, I would suggest you
organize a project to take the 2.4.2 beta 15 server and release something
that might be called release 3.0 or might have an altogether different name.

Hello,

Is it possible to have anon. ftp like account on a per users basis.
~~~~~~~~~~~~~~~

What I mean is the ability to have multiple anon. ftp like
accounts on the system.

For example, you could have a "user1" account with a set of
files below that and a "user2" account with a different set of
files.

This would be different than logging on as an existing user
since when you do that you have access to the entire system
(e.g. doing a cd / actually takes you to the root directory).
In this case, a chroot would be done that would limit the user
to just the directories under the "user1" or "user2" account.

Thanks in advance for any help.

With Regards,
Harshal

Hello folks.

OK, my /etc/ftpconversions and /etc/ftpaccess are set up to allow the
transfer of gzipped and tarred files (this is the default, I think). I
stuck a copy of gzip and tar in ~ftp/bin/ (this is under Slackware 3.4
Linux). However, when I do "get <foo>.gz" or "get <foo>.tar" I always
wind up with a zero-length file locally. There is something I'm missing
and it's driving me batty. ;/ The FAQ was searched, but that didn't help
much.

The version of wu-ftpd I am running is "(Version
wu-2.4.2-academ[BETA-15](1) Tue Nov 11 20:12:26 CST 1997)". Thanks in
advance for any help.

Keith Warno

PS -- One more thing, not related to sending compressed files... If I try
to log into the ftp server as a real user, give an incorrect passwd, then
type "ls", I get a message like:

ftp> ls
530 Please login with USER and PASS.
ftp: bind: Address already in use
ftp>

What's the "bind" line all about? Apologies if this is already in the FAQ
and I missed it. I'm curious if this is OS-specific or a product of the
server itself, and -- in either case -- if it's a problem or something
that can be safely disregarded.

I have reports that Netscape will use normal mode if it recieves and
error for PASV. I will be testing this soon.

That patch doesn't work for me (the version I used). It was suggested
that and hton?() may be needed for my intel machine. I will be trying
that also as it looks like a likely solution to be behavior I saw.

That is what is referred to as a guest acccount. Here is an example
passwd entry for a guest account:

norris:MrewJRqIUWg6Y:635:400:Norris:/home/ftp/./:/dev/null

The features are:

1) a /dev/null shell that is listed in /etc/shells yet won't allow
login.

2) a home directory that ends in '/./' to give a chrooted environment
to where you want to restrict them.

3) On my machine group 400 is 'ftponly' and ftpaccess is setup to
recognize ftponly to be of type guest.

I'm not using this feature anymore so I am a little shaky on the
details, but that is the basics.

Cheers!

Hi

I seem to be havinng problems with the mailing list. I can see my
messages on the list, but I used to get my message sent back to me also,
but these days I just receive everyone else questions/answers. So I have
re-registered under aslightly diffrent ID.

As to my problem

well theres 3 actually.

1.) When users create several subdirs , and they upload to say

~/iqbal/a/b/c the c subdirectory there permissions are not those in the
ftpaccess file. This problem was solved by alexey who mentioned that the
code in wu-ftp Beta[13] had been altered (for some reason).

2.) The second problem ws with usersname longer than 8 chracters.
wu-2.6[6] worked fine with long usernames, but beta[13] refuses to
recognise these long usersnames, anyone got any ideas

3.) I have about 1500 hundred users in the ftpaccess file. However
certain ftp packages such as wsftp are having problems logging in,
because of the long wait in checking the username/password. I have used
the bigpasswd patch , which worked fine for a few months, but since then
my users have gone through the roof. I have been told that its
effeicient to just [place the numeric uid/gid in the ftpaccess file,
this speeds up the process, but i dont know how to get wu-ftpd to read
these instead of the actual user/group.

Does anyone have a fix for this out there, or have similar problems.

Iqbal

Hi everybody,

I am looking for a freeware able to provide different statistics about FTP use.
I found iisstat which is pretty good (ftp://ftp.ccmail.com/pub/utils/InternetSe
rvices/iisstat/iisstat.html) but since it is quite old (1995), I was wondering
if there is any better one.
Moreover, with that program, I am able to generate a HTML output but in this
one I have no link to the GIF graphs generated. Any idea about that problem ?

Thanks in advance for your help. Gildas.

I'm not familiar with that particular program, but I've written one of my
own based on the old xferstats script. It keeps the name xferstats, but
has been rewritten in C and generates HTML, a few graphs, etc. It's
currently undergoing a massive semi-rewrite to increase the speed and
functionality, and as a result 1.20 won't be available for probably a
couple weeks. In the meantime, 1.16 is available at:
ftp://sod.off.net/pub/xferstats/xferstats-1.16.tar.gz

If xferstats doesn't do quite what you want, please drop me a note, I'm
looking for ways to increase what it does :)

I had a look at this last days. Here is what I began to hack into wu-ftpd :

- I set up a special guestgroup, say "LDAP"

- During authentication, for any user who fails to be anonymous, member of a
guestgroup or UNIX user, I do a LDAP lookup.
If it works, then the user is treated as "LDAP".

- In the chroot phase of the guestgroup login, I chroot the user to his own
directory (ldap/user1, ldap/user2, etc) so that directory trees of the
different "LDAP" users are totally distinct. If the chrooted environment
doesn't exist, I create it for him on the fly (just before the chroot).

Any comments ?

Ok. Time for some clarifications... First, this is what I wrote.

I wrote this out of frustration that the RFC2228 folks did not seem to be
working with the FTPEXT folks, with the pace of FTPEXT (which seems to be
picking up), with another currently publicly closed effort that is underway
to develop new features for FTP that they plan on "releasing to the world
as an RFC" (their words not mine) and with the pace of new enhancements into
wu-ftpd.

And before anyone gets the wrong idea here... I like Stan and I'm glad that
he stepped up and has contributed the work that he has. We are all better
for it. If you have any doubts about the sincerity of that, go look at the
Resource Center. Various pages have said the same thing for nearly a year.
There has been no change in my view of him or his efforts (from which we have
all benefited).

Stan Barber wrote:

We are all buzy and I know that you do this on your own time much like the
rest of us. Time is sometimes a very short commodity when we need to eat.
I understand that and so do the others.

The problem I see is by the very nature of what we are talking about we will
generate more bugs. :) That said, I don't see this impacting wu-ftpd at this
point. What you are doing is in line with what I have in mind.

We are going to need to do some setup work before we are ready to start a
real development effort. To just get started we need to:

* Review of the current code structure with suggestions as to its
reorganization to support module additions,

* Document an API to allow easily added feature modules,

* Examine of the feature set of emerging functionality to be added,

* Determine which features should be developed in parallel or in sequence
and in what general order,

* Setup systems from a baseline, development and mirror perspective,

* Setup administrative agreements as to how to decide what goes into
the baseline and when it is ready to do so,

* ...

A setup following the Apache model doesn't just happen overnight. It will
take some time just to get to the point where we can begin to seriously
look at changing a line of code. This is what I was talking about when I
said we need to address this. Without starting the setup work, the rest
just won't happen....

# It is my plan to work towards a release of 2.4.2 followed by an
# autoconfiguration version of the same server which I will call 2.4.3.

Don't slow any development down because of this. The two should work
well in parallel.

# After that, I had planned to significantly change the server in many of the
# ways the apache team overhauled the NCSA server. At that point, I was going
# to suggest that a project like apache be organized to provide modules for
# that new server that might implement some of the features folks want. That
# future (in my time line) was to start next year in the summer.

I agree that this is the type of effort that we need but waiting until next
summer just to start the setup and examination process seems a bit far out
when the only real changes you plan to make to the code are bug fixes and
and automated configure/build setup.

# The first
# release was to be a new basic server that would be compliant with the FTPEXT
# documents and would have a new API through which folks to build modules to
# hook in new features.

This sounds like a good starting point to expand things.

# This server would not implement everything in wu-ftpd
# at the first release, but would build up features on a module-by-module
# basis.

Ouch. This is not what I'd like to see. I would not want to field something
just to trade one set of functionality for a different set and then wait a
year to get back to where I was 12 months before. The work of the FTPEXT
should be be phased in over the subsequent months since there are different
documents describing different extensions. That's what I meant above by
examine and prioritize new enhancements. Personally, I doubt most current
wu-ftpd sites would want to go backwards and they would not field the new
server. This would splinter the community even more. What I and others want
is what we have now plus the new capabilities. Until we could do that I'd
vote not to release it. (And you're right, the module approach is the best
approach.)

# At that point, my job would be to maintain the basic server and
# perhaps house a module repository (with appropriate mirror sites) and look
# to others to build and maintain modules. The biggest help to me in making
# that happen would be to define the API as well as the basic feature set for
# the basic server.

I really don't care where the baseline is housed. I am looking at the process
and the results that are running on systems across the net. Foundation,
Features and the Flexibility to implement them on a timely basis is what
we need to put in place. (My 3Fs. ;))

# For those of you who can't wait for those developments, I would suggest you
# organize a project to take the 2.4.2 beta 15 server and release something
# that might be called release 3.0 or might have an altogether different name.

This is not going to happen correctly overnight. This will take time to
setup; but we have to start now. People willing to make a commitment to the
project have to be located. The internal architecture of the server and
the API do not happen overnight, much less get documented. These two efforts,
the current wu-ftpd and the foundation for ngwuftpd (next generation wu-ftpd)
need not be at odds with each other but can be in sync.

On a side note, I want to publicly thank Stan Barber, and others, who have
continued the wu-ftpd effort. I think we all can say we benefit highly
from their contributions. I certainly can appreciate his standing in
balancing his "real work" with his contributory efforts.

THANK YOU Stan.

'bison -y' is the functional equivalent to 'yacc'. Is the -y missing?

ooof... I should have read more closely; too much mail. You are
right, and short of rebuilding bison I don't know what to suggest. I
use ftp://prep.ai.mit.edu/ as the source for GNU files; I think
www.gnu.org is also up.

Sorry if this is covered in a FAQ, or in server documentation, but I
didn't see it; pointers are welcome.

Here's my situation. I am trying to setup a system where only certain
groups have access to the Internet. Right now, I have a BSDI 3.1 system,
(running wu-ftpd), that contains a kernel modification which blocks
socket() and bind() calls to all but those in the "Internet" group. This
works fine. For example, a user not in the group can log in to the FTP
server, but are unable to do anything, (get, put, ls, etc.) while users in
the group can. I am trying to port this to Linux, and am having problems.
Users logged on the system are blocked as expected, but if they use the
FTP server, (logged in under their account), they have full functionality.

In other words, I only want users in a certain group to be able to log in
to their account via FTP, (actually, I don't mind if they can log in, but
I want to block any FTP transfers). Is there an easy way to implement
this in wu-ftpd, (i.e. so I don't have to modify configuration files
whenever a new user is added, or moved in or out of the "Internet" group)?

Thanks,
Karyl F. Stein

Hello,

I just set up wu-ftp for guest accounts and I have a couple of
questions about things. One easy and one hard. First the
easy one.

1. When a user creates a directory in a directory defined by
an upload directive in ftpaccess it seems to have open (user,
group) permissions. How do I change that? The permissions
defined in upload are for files only as far as I can tell.

Now that hard one which is somewhat related

2. If every "guest" has the same directory structure and I would
like different permissions (however same for each guest user)
on the files that are uploaded in the various directories do I have
to put a set of upload directives in the ftpaccess file for each user.
I seems to me it would be possible to have "aliases", but I cannot
find any documentation on it. For example in ftpaccess can you
do something like this?

upload <guest home> * no
upload <guest home> /www yes <guest id> <guest group> 0600 dirs
upload <guest home> /cgi-bin yes <guest id> <guest group> 0700 dirs

Where <guest home> is whatever it should be automatically depending
on which guest logged in. Same with <guest id> <guest group>.
Right now I am defining those things manually for each and every
user!

Thanks
- Dan

We are trying to overcome permission/access rights with FTP accounts and
it was recommended that we move to wu-ftpd. I have got the latest
version (Beta 15) and have set it up on our test server (RS/6000 running
AIX 3.2.5).

I am trying to setup the 'ftpaccess' file, but I seem to be having
difficulty understanding the relationships.

Has anyone got a live sample of this file or snippets of one which I
could look at so I can get some pointers ?

Thanks in anticipation....

Is there any security reason to not use /bin/passwd for a shell for a
chroot, guest user so they can change their password anytime they want?

here is the /etc/passwd entry that I'm talking about to be clear:

focus:123432:101:101:Focus Comics:/usr/ftpusers/focus/./:/bin/passwd

or am I opening myself up wide open?

Subject: using ftpconversions

Hi,

i apologize if this is in the FAQs somewhere (i could not find it)...

I use wu-ftpd-academ-2.4.2.13 under digital unix 4.0b and try to use
ftpconversions without success.

I have it in the same directory as ftphosts, ftpaccess and ftpusers
and with these latter i could play around successfully.

I have built a statically linked version of gzip and gnu-tar and put them
into ~ftp/bin, but whenever i login via ftp and try 'get <file>.gz' or
'get <file>.tar' the only answer i get is "<file>.gz" not found, no such
file or directory. This is true for ftp via anonymous and for ftp via a
normal userid...

What did i miss?

Thank you!

Hello managers,

at last i've found the solution in the archives, more than a year ago...

My problem was to "allow" the programs to be used from ftpconversions
in an appropriate way within ftpaccess.
Some lines like

tar yes local remote

See the mail of [email protected] (Magali BERNARD)
with the subject Summary : wuftpd TAR+COMPRESS
from Mon, 28 Oct 96 09:53:02 +0100

Thanks,

Bernt

My question was:

> (which was no problem under ultrix)

> I have wu-ftpd-academ-2.4.2.13 under digital unix 4.0b.

> I have ftpconversions in the same directory as ftphosts, ftpaccess and
