              1. ftpd allways says "221 Server shutting down. Goodbye."
              2. Anonymous ftp works fine, but real users are denied
                 access
              3. ftpconversions doesn't work
              4. On-the-fly compression works, on-the-fly tarring, but
                 not both.
              5. I want to use zip compression (InfoZip)
              6. I want a real user to be able to access the host only
                 via ftp, not via telnet
              7. Somebody uploaded a file with a weird name
              8. I want anonymous users to be able to upload files, but
                 in the most secure manner possible
              9. The default umask used when a real user uploads a file
                 is wrong
             10. I heard something about 'SITE EXEC' having a security
                 hole
             11. How do I make reports more readable ?
             12. Incoming file transfers fail with SunOS and an NFS
                 mounted incoming
             13. Normal ftp clients work, Netscape ftp's fail. So,
                 passive mode doesn't work.
             14. I made a symbolic link within the anonymous tree and it
                 doesn't work for the anonymous users.
             15. I want to redirect anonymous users to another machine
             16. ftpd stops accepting connections when a lot of
                 connections come in.
             17. Running wu-ftpd on a *large* site
             18. Only the first 8 characters of the anonymous username
                 are recieved by the server.
             19. wu-ftpd fails with '500 Illegal PORT Command' under AIX
                 4.3
             20. I want to host multiple ftp servers on the same machine
             21. I just upgraded and now nobody can log in. It worked
                 before.
        12. Other things
              1. Where is the FTP protocol documented ?
              2. How can I make my ftp-archive accessible by Email
                 (ftpmail) ?
        13. Credits/miscellanious
              1. How do I contact the WU-FTPD Development team
              2. I have a correction / new feature, how do I submit it
                 for the WU-FTPD Development team's consideration
              3. I have what I believe to be a critical security problem
                 with the daemon and don't want to talk about it via
                 email. Can I call someone on the telephone

You send an unsubscribe message to majordomo NOT to the list.

A change in WU-FTPD version 2.5.0 was to use the supplied udpwtmp()
function to handle wtmp logging.  Unfortunately, udpwtmp() turns out to be
overly simplistic and unreliable.

This correction allows WU-FTPD 2.5.0 on systems using GNU libc version 2 to
record logout information in the wtmp file.  Primarily, this effects Linux;
other systems may be effected.

The fix for this problem is available from:

  ftp://ftp.wu-ftpd.org/pub/wu-ftpd/quickfixes/apply_to_2.5.0/glibc.wtmp.patch

This reverses an earlier change to src/logwtmp.c.  The original comment was:
Garry Shtern <shterng@akula.com> submitted a patch on Fri, 9 Apr 1999, whic=
h he
says was needed to support glibc2 on linux.

It turns out this has the effect of breaking wtmp logging on Linux.  The GNU
libc updwtmp() function cannot find _PATH_WTMP when a guest or anonymous us=
er
is logging out because the daemon has chroot'd.

Yesterday I downloaded 2.5.0.  I installed it on a Solaris 2.5.1 machine and
it works fine.  Today I installed it on an HP-UX 10.20 machine, and it doesn't
work fine.

It rejects logins, both anonymous and regular.  In the error log, the anonymous
login looks like this:
Aug  3 10:24:05 glast ftpd[13056]: FTP LOGIN REFUSED (ftp not in /etc/passwd) FR
OM glast [36.92.0.110], anonymous

The regular login:
Aug  3 10:24:15 glast ftpd[13058]: failed login from glast [36.92.0.110], pln

Here's what I know:

* There is an entry for ftp in /etc/passwd:
ftp:*:103:30:FTP server:/home/ftp:/usr/bin/false
In fact, anonymous ftp works with the HP ftpd.

* /usr/bin/false is in /etc/shells

* ckconfig is happy with my configuration files

* I believe ftpaccess is readable.  It's clear that ftpcount can see it.

* At first I started ftpd with the options -l -a -o.  I took all those out,
and it doesn't help.

* There was some problem compiling.  Since I use gcc, I had to remove some of
the HP-specific compiler flags in the Makefiles.  I just let the script put
the files wherever it wanted to.

* Yes, I did remember to HUP inetd after each change.

* I typed my own password enough times to be confident it's not just a typo.
The anonymous password checking is "trivial", so that's pretty easy to get
right.

* There's not much fancy stuff in my ftpaccess file.  Here it is, just in case:

* There's some history I didn't mention.  I had a very old version, which worked
OK.  I don't remember the number.  That's where I developed that ftpaccess.
Months ago I upgraded to one of the 2.4.2-academ versions (14? 18?).  Guest
and anonymous ftp access quit working then.  I can live without those, so I
let it slide.  Now it's worse.

I just went through simliar hell for installing 2.5.0 on HPUX 10.20. 
Greg helped me a lot to solve it.  I don't know whether this is same
problem but I sure had trouble logging in; I tested with 'ftp
localhost'

So, here is my 2 cent worth of comments.

One place you might look is whether either /usr/bin/ksh or /usr/bin/sh,
depending on what you use, is in /etc/shells.

According to Greg, you must have '-a' for 2.5.0.

This is the Makefile.hpx I used.  Notice that I am using bison, instead
of yacc.

I am running wu-ftp on a Caldera v1.3 Linux server. I'd like to keep as
current as possible on wu-ftp but it takes a while for Caldera to
generate their new RPM's. Can I use the Red Hat RPM's on the ftp site to
upgrade my Caldera? If not, what are my other choices? I am a total
newbie when it comes to compiling source.

Thanks.

I'm given to understand Caldera uses standard Redhat RPMs.  So the RPM
should install.  The only question is if Caldera changes any of the file
locations from the defaults Redha uses; you'll not know unless you
look/try.

The other way to upgrade would be to grab the current release, unpack it,
apply the quick fix patches for that version, and build the daemon
yourself.  IMHO someone who wishes to be as current as possible would
choose this method since it does not rely upon any third parties; just you
and the prinicple maintainers.

Can someone please tell me what the following error might mean?

...<snip>... ftpd[4248]: getpeername (in.ftpd): Transport endpoint is not 
connected

I started getting this message a few days ago but it is only when a certain 
machine (a mainframe that has some automated procedure for trasfers a bunch 
of files) tries to connect. Other machines from the same location can ftp in 
and login w/out any problems. I haven't had any problems with this before 
until Sunday morning. Does anyone know what maybe causing this. It is fairly 
urgent to get that machine able to ftp in again.

TIA,

Cory Derrick

Disregard... I found the problem. Just as the error message says, it 
couldn't get the peer name. My ftp server couldn't get a name for the ip 
address that was trying to connect. I guess tcp_wrappers requires a reverse 
name lookup before allowing a connection. Since it couldn't resolve the ip 
address, it denied the connection. I added the ip address and hostname in my 
hosts file and it worked.

We are running two ftpd deamons, one for internal users and one for internet
users. The internal users can drop files, which are then accessible to
internet users, but not internal users. The internet users can drop files
which are accessible to internal users, but not internet users. (i.e. the
transfer is only one way for each user type).

The internal users can put and get files, but if they create a subdir, they
can't cd to it or drop files in it. When I look at the server, the directory
permissions of the subdirectory are set for internet users, instead of local
users.

ftp-access seems to be set to allow creation of subdirs and to drop files in
subdirs.

If you're not running 2.5.0, upgrade to it.  Read the new manpage for
ftpaccess and read the upload.configuration.HOWTO.  BTW, I don't see any
partcilar reason for running two different servers for the problem you've
outlined.

I have upgraded my wu-ftpd to 2.5.  Now that i have done that my ftpusers
are not chrooted to there dir.  I havent change anything in the passwd file
or in the group file.  i still have the users dir as
/ftp/usr/username/./webdocs/:/ftp/only.  Does this still work in 2.5?  Or do
i need to add something else to get this working.  I went through all the
help files and I still get the same thing ive already gotten.  Can someone
help me out?  Thanks for your time

Check that the daemon is looking at your ftpaccess file: -a option on
command line, ckconfig command to check file is there and readable.

Does anyone know why wu-ftpd-2.5.0/makefiles/Makefile.sol has:

BINDIR=         ${DESTDIR}/usr/sbin
and
SBINDIR=        ${DESTDIR}/etc

when every Solaris box I've worked on needs:

BINDIR=         ${DESTDIR}/usr/bin
and
SBINDIR=        ${DESTDIR}/usr/sbin

Is this something peculiar about my boxes or a bug?

Thanks - Dave.

In 2.4.2 and earlier versions these were called BINDIR and ETCDIR
respectively.  I renamed them for consistency across platforms.  And
because, quite frankly, I wanted people to see eactly the kinds of dumb
things as you're pointing at.

Here's the phylosophy:

  The WU-FTPD, by default, is a drop-in replacement for the old, original
  BSD ftpd.

What that means is, for installation, the Makefile should put the WU-FTPD
daemon where the BSD daemon which originally came with your operating
system appears.  Now, you have to remember that all this is based on FIVE
to TEN YEARS AGO.  Worse yet, the configuration and installation files for
your (read: any) platform were done be someone with no time and little
knowledge (read: some FTP site administrator) whose only qualification to
do the work was he/she took the time to report back what was needed to get
it to work.

My personal take on it:

  Both locations are incorrect.  So is POSIX and the Single Unix Standard
  (or whatever the "standards" are Redhat claims when asked why they put
  something in the idiotic spot they did).

The correct location to install a package is /usr/local/<packagename>.  If
you need an /etc/<conffile> for the package, it should be a symlink to
/usr/local/<packagename>/<conffile>.  If you need several config files (say
Sendmail), /etc/<feature>/<files> is good.  I have /etc/ftpd /etc/mail
/etc/ntpd and so forth; makes things in /etc a lot easier to take care of.

I've tried a lot of other schemes; I like this one because it keeps the
packages separate.  The only thing I really don't like about it is all the
symlinks (which is why I'm moving toward /etc/<feature>).  But it is nice
knowing that all files for a package are in one place.

What do you want it to mean?

You may choose anything EXCEPT "two names sharing an IP number" .. FTP
(not the software .. the protocol) does not provide for having different
"named-based virtual hosts sharing the same IP address".

Ken,

Change your password file to be /ftp/usr/username/webdocs/./:/ftp/only

I've found that this configurations seems to work better with regard for
change-roots.

Also, make the corresponding changes in your ftpaccess file - since you
will now be chrooted at the webdocs livel.

This is the probably the same problem that Michael St. Laurent asked
about 30 jun on this mailing list, but I couldn't find the solution to
the problem in the archives.

I would like guest users (I don't have anonymous access) to only be able
to access the /foo/ftp directory so I entered the following in my
/etc/wu-ftpd/ftpaccess:

  restricted-gid ftp nogroup

and setting their home directory in /etc/passwd to /foo/ftp

This works but it would be much safer to use a chroot'ed enviroment,
which means replacing the line above in ftpaccess with the following:

  guestgroup ftp nogroup
  guest-root /foo/ftp

and setting up /foo/ftp/{etc,bin,lib} correctly.
This works fine, except that uid/gid isn't decoded to real names.
I have set up the passwd and group files correctly, even tried with
copies of /etc/passwd and /etc/group and altered the users home
directory entry. In the bin directory I have a dynamically linked ls and
my Linux system says (using ldd) that the only libraries needed in lib
are libc.so.6 and ld-linux.so.2 (with the correct local symlinks, of
course). I have even tried to copy the complete /lib directory to
/foo/ftp/lib.
Still ls -l won't translate the uid/gid numbers to names.

(Seems the list processor doesn't like me. Ok, once again...)

I've got a request by a customer. He complains that, when retrieving
large files, the reply "226 Closing data connection" appears long before
the transfer really completed. The customer remarks, that he has tested
it on different servers, but only on our server the problem happens.

We are using BeroFTPD-1.3.4. Can someone agree, that this problem
exists? Is it a bug (or perhaps a feature)? Or do I have to look
elsewhere?

BTW: What's going on with BeroFTPD, long nothing heard about it? Will
all it's features (especially improved virtual servers) be implemented
in WU-FTPD 2.6.0 or will it live on?

Thanx,
Andreas

The problem with your second attempt is an incomplete setup (no passwd or
group file to map the numbers to names).  See the FAQ and the Guest HOWTO.

I'd use BOTH methods.  chroot people to a common point then restrict them
to their homes.  That way I only need one copy of the glue stuff needed for
chroot and I still keep them separate.

This is exactly why I use GNU Stow.  It makes all the symlinks and verifies 
that none over-write existing ones.
         config --prefix=/usr/local/stow-dir/package-name

allows me to install it as:
         /usr/local/stow-dir/package-name/bin
         (etc)
and then cd to /usr/local/stow-dir  and issue the command
         stow package-name

Which creates all the symlinks to all the appropriate /usr/local/ 
directories. unstow inverts the process and cleans up all the symlinks 
without deleting any of the actual binaries or config files.  As a result, 
swapping between versions of packages verges on trivial. Stow it and test 
it. If it works, fine; otherwise, unstow it and stow the old one again.

Your customer has lame client.  And I wonder which other daemons they
tested against.

That said, yes, the WU-FTPD daemon (and, therefore BeroFTPD) sends the 2xx
message immedeately after closing, and does not wait for the data socket to
close down.

One of the changes I've submitted for 2.6.0 (at the request of another user
in the field) is to force the daemon to wait until the data connection is
closed before sending the 2xx message.

I'm currently testing this change on ftp.wu-ftpd.org.  It seems to be
working about 99% of the time.  The problem I'm seeing is that sometimes
the daemon isn't timing out .. so I guess I'll be doing a little tweaking
in a bit.

It's a (true) bug in the client which is tickled by a bug (oversight) in
the daemon.

The caveat is that /usr/local/ may be used for SW that is available to all
machines at a site (via NFS). At such a site, the above makes for a tidy
installation at the expense of added network traffic.

Same for /opt/<packagename>.

In response to the original post, /usr/sbin/ and /etc work on my
Solaris boxes although it scatters files all over the system and
makes a general mess.

Greetings,

Probably off-topic, but...

I usally don't trust 'make install' for most packages. Most of them
installs where they were supposed to, but I have also discoverd some,
like Gregory mentioned, which scatters files around and makes a mess.
wu-ftpd is definetly not one of theese though.

Anyhow, I usally keep the entire distribution under /usr/local/pgm. Like
this:
% ls -F /usr/local/pgm
/usr/local/pgm:
wu-ftpd@    wu-ftpd-2.4.2-vr16/    wu-ftpd-2.5.0/

Where wu-ftpd is symbolic link pointing to the current release. In this
case:
ls -l wu-ftpd
... wu-ftpd -> wu-ftpd-2.5.0/

In /usr/sbin on our Solaris server there are symbolic links for ftpd,
ftpwho and ftpcount which are pointing to
/usr/local/pgm/wu-ftpd/bin/ftpd etc.

This makes it very easy and fast to upgrade to a more current release.
Download the latest tar-ball, unpack in /usr/local/pgm, make, and change
the wu-ftpd link under /usr/local/pgm, to point to the new release. The
/usr/sbin links will still remain and will point to the new release.
This way we never need to run a make install after a make, it simply
just works.

Subject: mac clients ls hangs

Hi all,

I'm turning to this list as a last resort, so I hope it's not an 
inappropriate topic.  I'm trying to connect to a friend's redhat box 
running wu-ftpd 2.5.0, using a macintosh and various ftp clients (fetch 
3.0.3, websynch, anararchie).  At seemingly random times, my mac client 
will hang when getting a file listing.  I get the entire list of files, 
but the client just hangs, until I hit abort or it times out eventually.  
It happens randomly, and not always on the same directory.  Sometimes, a 
dir will list, then the next time it won't.  

I've used my same setup and software, and I can connect to my isp's ftp 
server (wu 2.4.2 acad 18) fine with no problems, so I don't think it's 
me.  However, I don't really know what the problem is server-side, to 
fix.  I couldn't find the answer in the faq or the mailing list archive.  
We compiled a static ls and put it in ~ftpd/bin, but it didn't help.  All 
my dirs and the parent dir of my $HOME have read and execute permissions. 
 Also, a command line ftp works fine, of course.

Any ideas?  Thanks in advance,
Brian

All at once yesterday, some files that have been uploaded to our FTP
site are showing a date that is exactly one year wrong (1998) when
viewed from Netscape.  It happens on both M$-based Netscape and Linux
Netscape as well. However if I go to the server and type "date" at the
command prompt, the date is correct. Also, if I look at the directory
using the "Home Directory" icon in KDE the date is correct.

What's going on here?

Hey guys - one more time.  GNU stow takes care of the location problems and 
intermingling of files from different packages. Why reinvent the wheel?

http://www.gnu.org/software/stow/stow.html  Which says:

GNU Stow

GNU Stow is a program for managing the installation of software packages, 
keeping them separate (/usr/local/stow/emacs vs. /usr/local/stow/perl, for 
example)
while making them appear to be installed in the same place (/usr/local).

You can read the Stow manual (52k characters) on-line.

Stow is a Perl script which should run correctly under Perl 4 and Perl 5. 
You must install Perl before running Stow. For more information about Perl, see
http://www.perl.com/perl/.

Stow was inspired by Carnegie Mellon's Depot program, but is substantially 
simpler. Whereas Depot requires database files to keep things in sync, Stow 
stores no extra
state between runs, so there's no danger (as there is in Depot) of mangling 
directories when file hierarchies don't match the database. Also unlike 
Depot, Stow will never
delete any files, directories, or links that appear in a Stow directory 
(e.g., /usr/local/stow/emacs), so it's always possible to rebuild the 
target tree (e.g., /usr/local).
Stow is free software, licensed under the GNU General Public License.

       Changes in version 1.3:
             Added --restow option.
             Fixed handling of slashes in package names.
             Expanded configure-time search for Perl binary.
       Changes in version 1.2:
             Dependency on `pwd' removed.
             Perl 4 compatibility fixes.
             Manual expanded even more.
       Changes in version 1.1:
             Long and short options now accepted.
             Manual expanded.
             `make clean' removes stow (which is generated from stow.in).

Please mail comments, questions, and criticisms to the author, Bob 
Glickstein, <bobg+stow@zanshin.com>.

Sounds like a bug in the client.  Do away with all clients, use the
telnet.testing.HOWTO to see how to by-hand see what the daemon is sending
in responce to NLST -al .. compare that to what you see on the screen.  If
not the same, then there you go.

hello,

I think that you haven't forgotten my last message.
But I will try to explain it with my poor english.

At work, I've installed Linux Redhat 6.0 and I'm using 
wu-ftpd to share files. The computer is a 486DX2-66, and 
all works perfectly.

At home, I've installed Linux Redhat 6.0 and I'm using 
wu-ftpd in order to give a large space of archiving to my 
demo group. The computer is a BI P-III at 500Mhz (YES !!!), 
and it have got little problems:

- The ftp client, (I've tested many of it) tell that it 
connected the server and wait for welcome message. But, 
this welcome message take a long time to be displayed. On a 
range of 2 or 3 minutes !!!!

- The second problem is: when I upload, I cannot have a 
transfert rate more than 500Ko/s !!!! Whereas the download 
have no quota and can send data in 100Mb/s in full duplex 
mode.

The last answer gived to me is:

< * Try the last version of wu-ftpd, look at the special  
version for redhat

I tryed it, and there is NO changes.

< * It's probably a kernel problem !!!

If there is, how to understand the fact that the download 
works perfectly ??? Which mean that the network card also, 
works perfectly, like all the other services. (httpd,...)

HELP, please HELP, It's my ONLY unresolved problem !!!

Thanks, for you answer.

I've just installed a RedHat 6 system. As the hard drive was 540MB 
I choose packages rather than use the EVERYTHING option. Now 
I'm trying to get anonymous ftp working. All is well Except that when 
I run WS_FTP Pro (a Win32 program) into the pub directory I see 
no files there. I can retreive and send files as long as I can specify 
the filename I know is there.  
I've set up several RH6 systems with the EVERYTHING option and 
all works well. What gives?? Answers/Ideas of course welcome --

It was a network card configuration problem, but I don't

I made a 'rmmod' and an 'insmod', that's all !

Thanks for your " online-support "

  I'm running wu-ftpd 2.5 on a RedHat Linux 5.2 (kernel 2.0.36) server.
  My problem is with tunnelling ftp over ssh. After making the
connection and authenticating to the ftp server, it replies with:
possible port theft cannot open data connection.
  This did not happen with version 2.4.

  Any ideas?

  Thanks,

  Patrick O'Malley

No, but 2.4 is so insecure that having your data stolen is the least of
your problems.

I have a testing version of the changes which will be in 2.6.0 to support
sites like yours.  Email me directly and I'll forward a copy so you ca
'test' it.

Has anyone successfully compiled wu-ftpd 2.4 on freebsd version 3.0? I
had many errors when I tried to compile the beast.

Who cares?  Better yet, who really cares to remember that long ago?

Hello,

I have wu-ftpd on my Linux-Debian server and now I have a problem..

it's like this, if a user ftp in they get to their home dir, that´s ok, but then they can
go out from their home dir and go out to the whole hard drive and look at files and 
so on,so my question is, is there any way to do so that the users can not go out from
their home dirs, and is there anyway to exclude any user, I mean I still want to be able
to do that and not anyone else.

Best regards,

/Darijo

You need to run 2.5.0, read the Guest HOWTO and use the 'restricted-uid'
feature.

Hi!


I had an interesting result when we performed our Y2K validation.
We are running Version wu-2.1c(2) as our ftp server on an
SGI Challenge (IRIX 5.3). The SGI OS has been patched to
handle Y2K issues.

Our test for ftp compliance was performed by
synching the dates on a client and our ftp server;
both systems had dates set to March 1 2000.
A file was transferred to the ftp server. The time
stamp of the file was correct (Mar 1 2000 00:13) but
the entry in the xferlog file had a transfer time of
March 2 2000 00:13! Has anyone else attempted
a similar test and had similar or differing results?

I cannot imagine why anyone would bother.

Your system is so old and has such severe security problems, I'm sure the
hackers using it (and I'd not be surprised to learn there's been a few
thousand of them) just chuckle and overwrite your system logs using the
lame dates so you'll not notice.  That's if they even both letting you see
your system logs.

For purely acedemic reasons, if you actually have the _original_ source kit
to a version of the deamon that old, I'd be interested in adding it to the
attic area of the ftp site .. not that anyone would ever want to use it,
but it might be nice to have some of the old, lost code like you're running
in case someone wants to know when Bryon added a particular feature.

In the meantime, I STRONGLY suggest you completely disconnect that computer
from ALL networks and IMMEDEATELY begin the process of regaining control of
your computer.  If you need assistance, there's a good reference on
'Detecting and Recovering from a Root Compromise' at http://www.CERT.org/

I haven't tried this, but...

Version wu-2.1c is _very_ old (circa 1993 or 1994 I think), and has some
known security flaws, so you might want to consider upgrading to the latest
release (2.5.0).

Having said that, both 2.1c and 2.5.0 generate the date for the xferlog by
calling time()
   time_t curtime = time(NULL);
and later on calling sprintf, and supplying a format of "%.24s" with the
output of a call to ctime...

2.1c :-
   sprintf(msg, "%.24s %d %s %d %s %c %s %c %c %s ftp %d %s\n",
           ctime(&curtime),
           ...

2.5.0 :-
   sprintf(msg, "%.24s %d %s %" L_FORMAT " ",
           ctime(&curtime),
   ...

(It was discovered that sprintf() under some OS's was quite limited in the
number of parameters it could be passed; hence the reason the 2.5.0 call is
a shorter format string - the output gets concatenated with a subsequent
sprintf() call which produces the rest of the string.)

This makes me believe that upgrading to 2.5.0 may not fix the problem;
I wonder if IRIX 5.3 ineeds another patch to fix ctime()...  You could write
a small stand-alone program to test this hypothesis.

Of course, you may want to upgrade to 2.5.0 for other reasons, since you are
running such an old version at present.

Good luck !

Cheers, Bob

Hi, 

I have setup on a new server BeroFTPD, as I have on my old server. 
But I want to use now chrooted users. 

I have search in the mailinglist archive for infos and have found, that I 
must use guestusers. I have also setup this and if I try this with wu-ftpd 
2.5.0 it is working now without problems. But if I try the same 
configuration with BeroFTPD 1.3.4, it is chrooting only on anonymous 
access, but not with the other users. 
I have tried to compile this with other options and checked twice the 
correct location of ftpaccess, but don't have found the problem. 

Can somebody help me with that? 

Thanx!

You could use BeroFTPD to get this.  This is one of the cases where I've
always said BeroFTPD should be used.

Or you could use a fancy inet daemon (xinetd is what I use) and select a
different ftpaccess file for each vhost.  This works but is a pain to set
up.

If you organize your users so the ID numbers are arranged by the vhost you
want the user to use, you can specify those ranges on the guest-root .. ie:

 # No non-anonymous access on the default server
 defaultserver deny *=20
 # Except these three
 defaultserver allow user1 user2 user3
 # These users on vhost 1
 virtual vhost1 allow user4 user5 user6
 guest-root /home/vhost1 user4 user5 user6
 # And these on vhost 2
 virtual vhost2 allow user7 user8 user9
 # Users 7 through 9 are UID 20007 through 20009
 guest-root /home/vhost2 %20007-20009

Looking at the code for the defaultserver/virutal allow/deny, I see it ONLY
accepts user NAMES and does not accept UID numbers or ranges.  The code for
guest-root does.  It shouldn't be too much work to copy that code from
guest-root to the allow/deny functions.  [My head's into other things right
now or I'd offer to do it .. if you get it, send the patches along and I'll
propose them for an upcoming release.]

I'm sure Bernhard will correct me if I'm wrong ...

If you're talking about the old 'guestgroup' clause, this should be working
in BeroFTPD.  Probably the problem is a missing entry for the users in
/etc/group: there seems to be a lot of confusion by this on both WU-FTPD
and BeroFTPD .. the user MUST be explicitly listed in the named guestgroup
in /etc/groups for guestgroup to take effect.  With BeroFTPD this is
compounded by the possibilty of multiple etc/group files.

If you're talking about guest-root, ISTM this is one of the later features
of WU-FTPD which has not yet made it into BeroFTPD.

Hi,

I'm trying to configure wu-ftp in a chrooted environment. I am able to do it for
anonymous and guest user. How can I do the same for an existing real user?
Please advise.

Naveen Malhotra

The only difference between real and guest is the chroot .. make the real
users guests.  In fact, you should make ALL non-anonymous users guests:

  guestuser *

Some people like to leave one or two non-anonymous users a real.  I
recommend against this.

  realuser ftpadmin

You can also use guestgroup/realgroup but you need to remember the users
MUST be explicitly listed in /etc/groups for these to take effect.

I have installed the wu-ftp 2.5 on an AIX 4.2 system.
But the option -a is'nt recognized.
I have seen in the FAQ that I have to add some code. But I'm not 
a specialist in compiling and I don't know in which source file 
I have to add it. 
Could someone help me ?

Thanks in advance

Start by just doing a kill -HUP on inetd.  That should tell inetd to reload
the config file (/etc/inetd.conf) .. on most systems that's a  yo need to
do.

If you need more command-line parameters than inetd will allow (some
systems have a limit, someties a very low limit like 3) .. use a shell
script and yo don't need to write any code at all.  ISTM that's the "code"
you saw in the FAQ.

All,

in the university that i study every departament will have its own
FTP server. There will be some 200-300 virtual FTP servers. whats the
best solution ? Unique IP addresses or CNAMES entries in the DNS zone
file, something like this..

www3.mydomain.net  IN   A   some.ip.address

;
; Aliases
;
ftp.otherdomain1.com   IN   CNAME     www3.mydomain.net.
ftp.otherdomain2.com   IN   CNAME     www3.mydomain.net.

and so forth..  

whats the pros and cons of the two schemes?

thanks in advance

Reinaldo

The ftp daemon is unable to differentiate between connections made to
different DNS names (CNAMES), so if you use multiple CNAMES, then whichever
name you use to connect will always get you to the same server.

If you want the different virtual FTP servers to then have different ftp
root directories, then I believe that you have to use unique IP addresses,
and then set up virtual server definitions for each of them.

In either case, you are looking at a lot of fun - 200 or 300 IP addresses
on a single box, with it's associated ftpaccess file, or otherwise trying
to sort out the connections using login names or groups to decide which
part of the ftp tree that the user should be seeing.

Good luck,

James

Great, thanks for the answer.

How about flexibility of the to schemes. I want the department
administrator be able to create, remove directories, etc and an anonymous
area where he can put files to other people download (thesis, docs,
reports, etc). Is it possible for a administrator create other
administrator users? Well, I think this will happen many times, so would
be great if they have this power without having to be "root" or ask me to
do it.

best regards,

Reinaldo

Many of the features you're asking for are attainable using the current
2.5.0 base release.

=46rom the daemon's point of view, however, users are handled externally.  =
So
there is currently no way to handle the problem in the daemon.  You may
want to take a look at BeroFTPD .. it may offer features I'm unaware of.

The way I've handled the problem is to run the daemon completely chroot'd
(before startup) so it has a completely private /etc/passwd and /etc/group
file.  I then wrote a special SSH (don't like telnet for this) shell for
use in the chroot'd environment.  Users with authorized keys in this
environment are able to run {user,group}{add,del} in this environment.
They can also {up,down}load the local user's
~/.ssh/authorized_keys so they can grant or revoke permissions on the
server.  Non-root users get another version of the SSH shell which allows
them to manage their passwords and perform certain canned operations.



In specific response to the earlier question about CNAME hosts:

There is an IETF Working Group developing a solution to this problem.  This
solution is part of the 'mlst' draft proposal (available through
http://www.wu-ftpd.org/ ).  Basically, the proposal is to add a new FTP
command, HOST, which allows the client to select the host by name after
connecting to the IP address and before authorization.  BeroFTPD supports
the HOST command, as do NcFTPD.  At this time, the only FTP client I know
of which supports HOST is NcFTP (both the Nc client and server are for-pay
packages).

The WU-FTPD Development Group has a number of plans for the daemon.  One of
those is support for the HOST command along with the other 'mlst' features
and the other FTP features described in RFCs which followed 959.  We've not
decided yet whether these features will be put into the current source or
whether they'll have to await a complete rewrite (ie., version 3.x) and
we've not yet discussed a timeline for this development.

Hi,
looking through the mail list archives I found someone asking the same
question I've got about wuftpd. 

http://www.landfield.com/wu-ftpd/mail-archive/1999/Apr/0013.html

Is there some new functionality in wuftpd which lets me limit the number
of simultaneous connections from one IP? The advice to set the timeout to
a shorter time than default doesn't really help when the users willfully
connects 30 times and steals all the bandwidth... Although it do help a
bit against the IE users.

If not yet, is this a feature that is on the todo list of wuftpd?

Thanks.

Not yet.

Yes.

If the user is common from a known IP, you could create a special class for
that user's IP (or IP block) and limit the class.

Hi,

a nice feature for future releases would be support for CNAMES 
supporting different virtual ftp servers using one ip, just like in the 
http dimension with apache http server :)

what do you think?

yours, antonio

Yes, but.

The feature won't work since there's no client out there which support it.
IT's not yet an RFC, only an IETF Draft Proposal.  You can view the current
draft at http://www.wuftpd.org/rfc/draft-ietf-ftpext-mlst-07.txt

BeroFTPD supports the HOST command specified in this draft.  That support
is solely in support of the IETF FTPEXT Working Group's efforts.

NcFTPD (the server) and NcFTP (the client) support HOST as well.  These are
for-pay packages.  Their implementation of the HOST feature is also
experimental in support of the FTPEXT effort.

At this point, these are the only two servers and the sole client known to
support the HOST feature.

The WU-FTPD Development Group has merging BeroFTPD's implementation of the
HOST feature as one of its goals.  The feature will not be put into the
base daemon until the Draft becomes an RFC.  Implementation of HOST
requires implementation of a large number of other features which already
_are_ RFCs; obviously our first priority is to add support of the existing,
but unimplemented, features of FTP before we move on to the still-
experimental ones.  At least, this is how I see the development effort as
proceeding; another group member might decide he wants HOST now and put it
in anyway.

Not quite the same, HTTP (At least version 1.1) supports the facility
for the client to tell the server which site it is requesting (It sends
a Host: header saying something like http://www.foo.com).  The FTP
protocol doesn't feature any such thing AFAIK so it would be difficult
for the server to know which site it should serve.

This may change I s'pose ...

  I know NcFTPD is 'for-pay' but I always thought NcFTP was free. Was on
their site not to long ago getting the latest 3.0beta and don't remember
seeing anything about paying for the client, what did I miss ?

You should upgrade to 2.5.0.  There's an RPM for it if that's how you do
your installs.

You also need to read the FAQ.  It has the detailed instructions you need.

Todd,

Looks like your well on the way.

First - for security reasons, UPGRADE to 2.5.0 (ftp.wu-ftpd.org).  The
2.4.2 if full of security holes.

Second, you have to do a bit more work on your chrooted environment.  I'm
assuming that the ls is staticly linked.  If so, then all you probably
need is the /dev/zero entry in the chrooted area.  Note, ls will be
looking for password and group entries.  You can skinny down copies of
these files and put them in the etc directory of your chrooted area.

If your ls is not statically linked, you will also have to add the
corresponding libraries.

Hi Todd, 

Welcome to the list.

Firstly, I should point out that wu-ftpd 2.4.2 is a *very* old version
which has a number of security holes.  I would highly recommend that you
upgrade to wu-ftpd 2.5.0 as soon as possible.

Now, assuming that you upgrade to wu-ftpd 2.5.0, accomplishing what you
wish is a relatively simple task.  There is a document that is included in
the wu-ftpd 2.5.0 distribution entitled upload.configuration.HOWTO which
covers this and other issues in great depth.  I would suggest that you have
a read of this, and if you have any further problems, get back to the list.

The current version of wu-ftpd is available from the following locations:

ftp://ftp.wu-ftpd.org/pub/wu-ftpd/wu-ftpd-current.tar.[gz,Z]

Good luck,

James

hi,

platform: hpux, wu-ftpd-2.5.0, gnu tar-1.13, gzip (static)

when a guest user logs in, get <dir>.tar works, but
get dir.tar.gz says "no such file or directory".
i was hoping i can get a directory by taring  + gzip on the fly?

i use default ftpconversion.
i alo tried replacing "-z" with --use-compress-program:

 :   : :.tar.gz:/bin/tar -c --use-compress-program=/bin/gzip 
           -f - %s:T_REG|T_DIR:O_COMPRESS|O_TAR:TAR+GZIP

thanks

Some machines don't handle that very well.  Usually what you do is get a
'pipe' program and tell it to run tar, piping the results through gzip.

This may or may not be the case here.  All I can say is it must be an HP/UX
issue since tar+gzip works fine on other platforms using the default
ftpconversions.

No, that wasn't the problem ... 
I have found now the problem and I am wondering about one thing. 

I have heard, that the hostbased ftpservers like on apache, doesn't 
work, because this isn't official. I has setup before I tried that with the 
chroot a hostbased ftpserver, but forgot this, because I thinked it 
doesn't work. And it has worked, if I was used with only one IP 
different hostnames, that was the reason, that the changes on the 
default ftpaccess-file doesn't applied. I use AbsoluteFTP as ftp-client. 
Has this software implemented the hostbased feature, or why it is 
working on me???

Hi,

And thus it came to pass that I felt this pressing need to integratie
WU-FTPD with LDAP without any intervention from PAM. I have looked
around a bit but did not find an out-of the box solution that I could
use. I therefore decided to write my own. It seems to be working
allright (tested on Linux and HP-UX). I would like to share this code
with the WU-FTPD community so I include the files of interest with this
e-mail message.

Please beware that this code has a serious "0.1-under-development"
status. Please heed the warnings in README.LDAP! 
I would be interested to hear what people think and where it can be
improved. I would be happy to take in requests and see if, when and how
they could be implemented.

With this e-mail I include a recursive diff of the 'wu-ftpd-2.5.0' and
'wu-ftpd-2.5.0-ldap' directories. New/changed files in the
wu-ftpd-2.5.0-ldap directory are reflected in the diff output.
Currently, I have updated the Linux makefile only (my development
platform), modifications for HP-UX are underway. Included in the patch
is a README.LDAP file that explains some of the mechanisms employed.

Share and Enjoy! (motto of the Sirius Cybernetics Corporation :-)

> Configuring WU FTP for LDAP access
> ----------------------------------
> All necessary parameters for the LDAP connection have to be specified in
> the "ftpaccess" file. A couple of new ftpaccess statements have been
> added that allow the administrator to specify the connection parameters:
> 
> ldap-host     ldap.osp.nl
> ldap-port     389
> ldap-base     o=osp.nl
> ldap-user     uid=dirmgr, ou=Directory Users, o=osp.nl
> ldap-password secret
> 
> Sensible defaults exist for these parameters, so you do not need to
> specify anything. However, the "ldap-user" used in the LDAP connection
> must have enough permission to search the directory, retrieve user
> information and compare the user password to the value stored in the
> directory.
> 
> Configuring the directory for WU FTP
> ------------------------------------
> WU FTP looks up users with the search filter "uid=username". The user
> entries for which you want to allow FTP access *must* be of object class
> "ftpUser". Presumably this object class does not exist in your
> directory. The solution: add it using your directories extensible schema
> editor.
> 
> WU FTP expects the following attributes to be present in the user entry:
> 
> - uid                 the user name (string)
> - userPassword        (string)
> - uidNumber   the numeric userid (a la Unix, integer)
> - gidNumber   the numeric groupid (a la Unix, integer)
> - homeDirectory       the user's home directory (string)
> 
> The following attributes may be present:
> 
> - cn          the common name of the user (string)
> - gecos               a standard Unix gecos field (string)
> 
> You need to set up permissions in the directory so that the user that WU
> FTP uses has enough permissions to search through the directory,
> retrieve the attributes specified before *and* have "compare" permission
> to the userPassword field.
> 
> Regarding user password storage. WU FTP tries SHA, MD5 and clear text
> passwords before it gives up.

> 
> About the example
> -----------------
> In this example, I used the WU FTP guest user facility in combination
> with WU FTP LDAP. In the directory the numeric uid and gid of the user
> "test" are 1003. This is the actual uid and gid of a user and group in
> the system:
> 
> In /etc/passwd:
> extraftp:x:1003:1003:Extranet FTP user:/not/exist:/no/shell
> 
> In /etc/group:
> extraftp:x:1003:extraftp
> 
> So, the FTP daemon assumes the identity of the "extraftp" Unix user.
> Furthermore, in "/etc/ftpaccess" we have:
> 
> guestuser %1003
> 
> So, after having authenticated the user, WU FTP fires up its normal
> "guest" facilities, doing a chroot to the user's home directory (from
> the directory (/home/josv/tmp)) and restricts the user to that
> directory. Neat uh?

I found the question but not the answer in the mail archives so
unfortunately I have to
repeat it once again:

Specs: Solaris 2.6 Wu-Ftp 2.5.0

I can restrict the user anonymous to the directory specified in the
/etc/passwd
but I cannot do it for a regular user such as "bulent".

Of course I run the deamon with the -a option. And checked a couple of
things.
But since this is the first time I ever install and configure Wu-Ftp I
need a little bit
help.

Thanks in advance.

Real users can be restricted to a directory (like the anonymous user)
with the "guestuser" and "guestgroup" statements in the ftpaccess file.

e.g.
"guestuser bulent"

Hi Folks!

After a week I dedice to call for help.

My anonymous users cant 'dir', allthough 'ls' works. Since most users
are using W32 and something like WS_FTP or CuteFTP, they cant see
anything. But a user using a commandline driven ftp-client like in W95
can use 'ls' and it works, but he cant use 'dir' either.

All happens on a SuSe 2.0.36 (i586) with wu-ftpd.2.4.2.

I made a group ftpano and a user ftp in it.

Homedirectory of ftp is /usr/local/ftp, further I have following below
this directory:

~/bin/
~/etc/
~/msgs/
~/pub/

I download the static versions of ls, dir, compress and tar from GNU,
compiled and put them into ~/bin

In ~/etc I created a passwd and a group file like this:

#---passwd for ftp
anonymous:*:2000:4004:Anonymous FTP::
guest:*:2001:4004:Anonymous FTP::
ftp:*:2002:4004:Anonymous FTP::
#--- EOF passwd

#---group for ftp
ftpano:*:4004:ftp,guest,anonymous
#---EOF group

I chmod +rx -R ~

I changed the group of all files and directories begining with
/usr/local/ftp and below to ftpano. I know this is not the way to do
it, but I wanted to see if it helps.

One step further I changed the owner of all files and directories
begining with /usr/local/ftp to ftp. Same as above.

The symptom is still the same.

When a anonymous User logs in, he can type 'ls' and gets a list of
contents, when he types 'dir' he doesn't see anything, but still gets
the '226 Transfer complete.'-message, e.g. no error.

After searching and trying all man's faq's and how-to's I could get
hold of, I finaly see no other way than bothering you with my problem.
I am pretty sure it is just a little mistake I made which is an "Of
course you have to..." for the authors of the things I read.

Any hints?

Sascha

Hi,

	Wondering if upload will work with chrooted users.  It seems
to imply its for the anonymous ftp only. I'm basically trying to say
that all chrooted users can't create directories.

In /etc/passwd:

fred:x:111:111:Fred:/usr/ftp/./usr/fred:/usr/bin/false

In /etc/ftpaccess

upload /usr/ftp /usr/fred yes fred other 0600 nodirs


			Thanks, Tuc/TTSG

1) Yes, it works fine.

2) Dude, you are a Development Group member.  If the manpage is unclear,
   clarify it and commit that change for 2.6.0 :P

	Then given the example of:

fred:x:111:111:Fred:/usr/ftp/./usr/fred:/usr/bin/false

in the /etc/passwd


	What is the proper syntax for the upload line?

upload /usr/ftp /usr/fred yes fred other 0600 nodirs

			or

upload /usr/ftp/usr/fred * yes fred other 0600 nodirs


			or?????

 Hello,
I had to split ftpusers group since we do have about 500 ftpusers and the
line was too long.  I split ftpusers and created three groups.

Is this setup correct?
/etc/group:
ftpusers::60004:ftpgroup1,ftpgroup2,ftpgroup3
ftpgroup1::60005:smith, john, eva
ftpgroup2::6006:bcROP000, BwsWp009, BGSFp3345
ftpgroup3::6007:b087,b9843,b8972

I am getting this error messages when updating NIS:
# cd /var/yp
# make
make[1]: Entering directory `/var/yp'
updated group

Error talking to : unknown host
Cmake[1]: *** Deleting file `group.time'
make[1]: *** [group.time] Error 130
make: *** [k] Error 130
# 

Please help.
Regards,
Magda

Before I do upgrade to v. 2.5 (late afternoon), how can I make it working
correctly now? 
A)
I added to /etc/ftpaccess my new ftpgroup1, ftpgroup2 and ftpgroup3:
# specify which group of users will be treated as "guests".
guestgroup ftpusers,ftpgroup1,ftpgroup2,ftpgroup3

I tested  ftp   and this users are not treated as   "guests" and can go
anywhere.

--Q1 
Is there something else to do?
1. /etc/group file (split ftpusers lines)
2. /etc/ftpaccess file (add new groups to guestgroup)
2. re-start inetd

I checked the current version (2.5.0) and sure enough the code is
potentially vulnerable (I say "potentially" because it depends on having
MAPPING_CHDIR defined at compile time, which I'm not sure is or isn't
the case in all installations).

The patch supplied by Michal misses one potential overflow, though, and
makes an improper assumption about MAXPATHLEN (he hard-codes his length
check to 4095 bytes, while MAXPATHLEN on at least some Linux systems is
1024 bytes!)

I have prepared a patch myself (appended below my signature), against the
wu-ftpd-2.5.0 source found at ftp.vr.net/wu-ftpd/wu-ftpd-2.5.0.tar.gz.
Please look this over and consider incorporating it into a future release
of the distribution. In the meantime, I suggest that admins should make
a point to apply this patch.

Go to the binary exposed in /etc/inetd.conf.  run strings on it:

  strings ftpd | grep ftpaccess

The access file is usually the second line listed.

The WU-FTPD Development Group released a patch for this problem yesterday.
That patch includes yet another case missed by your patch.  The
announcement of that patch is available through our web site:

  http://www.wu-ftpd.org/

and is on our ftp site:

  ftp://ftp.wu-ftpd.org/pub/wu-ftpd/2.5.0.Security.Update.asc

please refer to that announcement for a full discussion of these issues.

The machine which I didn't upgrade to (Version
wu-2.4.2-academ[BETA-18-VR15](1)
and still is running the old (Version wu-2.4.2-academ[BETA-13](1) doesn't
say that FTP Server started without ftpaccess file...

# strings /usr/local/etc/wuftpd  | grep ftpaccess
Too many args (>%d) in ftpaccess: %s %s %s %s %s ...
/etc/ftpaccess

All machines with FTP which I upgraded to v. 18 give me messages about
server started without ftpaccess file.

Please advise,
Magda

One of my changes was to syslog a message if the daemon started without
using an ftpaccess file.

The reason is there was a change some time ago (one of the academ betas)
which switched the default from -a (use ftpaccess) to -A (don't user
ftpaccess).  The reasoning behind the change was the old NET-2 (BSD) ftp
daemon did not have an ftpaccess file, and WU-FTPD is supposed to be a
drop-in replacement for that daemon.

The result was a new FAQ.

To fight that, I added a syslog message in one of the later -VR updates.

The long and the short of it is yo need to be sure the -a option appears on
your inetd.conf line which executes the daemon.  And yo need to be sure the
syntax of that line is correct .. some people on some systems forget to put
'ftpd' for arg0, so the '-a' becomes arg0 (the program name) and the daemon
never sees it.

You should download the patches from ftp.wu-ftpd.org and then you'd not
need to worry about typing or MIME/mailer munging.

Hi all, I need some help configuring wu-ftpd for assigning multiple 
guest groups to class.

Here's what I'm trying to do:

I'd like to set up 2 classes of guest users, with each class having a 
maximum # of users.

In my case, I have 2 groups of users, ftponly1 and ftponly2.  There 
are multiple users in each group, each with their unique Login.  I 
want to allow maximum of 5 ftp users from each group, with chroot() 
guest access.

So I've entered in /etc/ftpaccess the following:
...
class ftponly1 guest *
class ftponly2 guest *
guestgroup ftponly1 ftponly2
...

Of course this doesn't work because users from _either_ groups would 
be classified as ftponly1 and the max limit for one group would 
applied to both groups of users.

I'd appreciate a direct email, the listserv traffic is not completely 
coming through and I have no idea why.

Thanks,

Groups cannot be members of other groups (ftpusers)

I don't use NIS .. or NIS+ (which is what I hope you're using), so I cannot
help you.  Maybe someone else ...

Fix /etc/group (delete ftpusers) and try again is all I can suggest.

User IP address selection on the class.  If that won't work, you'll have to
wait for me to finish rewriting the ftpaccess file handling .. could be a
few months (read as: I'm working on other stuff right now).

OK then, I'll wait :-).  Meanwhile, does anyone know if there's 
anyway to chroot() a real user?

The last one should work, but this might be better:

upload /usr/ftp/usr/fred /usr/fred yes fred other 0600 nodirs

That should work.  Did you remember to kill -HUP the inetd process if youu
changes the inetd.conf?  Gotta do that.  Won't hurt, so do it again, to be
sure.

Make sure the ftpaccess file is readable and in executable directories.  It
should be (you've been editing it) but check anyway.

Run ckconfig.  What does it have to say?

Both of the following accounts are in /home.
But one of them show the full path name /home/joel/testfile.zip and the
other one show a relative path name /angie/test.zip

The way I read the RFCs is this:

  A command without parameters must NOT have any trailing spaces.  So

    PWD <SP> <CR> <LF>

  is an invalid command.



  A command taking parameters must have EXACTLY ONE space between the
  command the the parameter.  So

    CWD <SP> /pub <CR> <LF>

  is valid, resulting in the C function

     chdir("/pub");

  where

    CWD <SP> <SP> /pub <CR> <LF>

  is also valid, but probably results in and error.  It becomes the C
  function

    chdir(" /pub");

  Since your cwd probably does not include the directory " ", this probably
  results in an error.



  A command taking an optional parameter must have EXACTLY ONE space when
  the parameter is present, and NOT have any trailing spaces when it is
  not.  So

    CWD <CR> <LF>

  Means "take me home" and becomes the C function

    chdir(pw->pw_dir);

  where

    CWD <SP> <CR> <LF>

  should resolve to either

    chdir(NULL);

  or

    chdir("");

  resulting in an error.  Notice the meaning is "here's a parameter ..
  nothing at all."



In summary, your Netscape web browser is not speaking FTP.  Upgrade to the
latest version.  If the problem recurs, report the bug to Netscape.

I'm not sure if this is a bug or it supposed to behave that way.  If a
client sends a command w/trailing spaces, the command is unrecognized by
the parser.

We stumbled across this while trying to figure out why
ftp://uid@ftp.wu-ftpd.org  (without the trailing slash) from within the
web browser sometimes returns a "netscape is unable to find the
directory /.  Check the name and try again" error message.

After some mucking around with telneting to port 21 and snoop, we found
that when you leave out the trailing slash in the URL, the Netscape ftp
client sends "<command> " (Note the trailing space). This is probably a
bug w/in the client (I assume it's expecting an argument and is doing
somthing like sprintf(buffer,"%s %s",command, url_args) and if URL_args
are null, it sticks it on there anyway.  I've filed this as a bug at
netscape. In any case...

This happens on any command.  See below:   Line 'u' is a "CWD" and line
'x' is a "CWD " (with a trailing space) that fails.  Line Z illustrates
that it happens on other commands as well.

My question -- is there a problem with stripping the white space from
the END of the input line?  In our implementation of the ftp server, we
changed ftpcmd.y.  Our local version now has a fix to getline() that
strips trailing spaces before handing it over to the rest of the
parser.  Is this a bad thing for some reason?   Or has it just never
come up?

Start by upgading to 2.5.0 (at least, ISTM 2.5.0 will ONLY log the full
pathname).

There may be a compile-time soption in 2.5.0 to change this behavior back
to the old way, but I don't remember if I thought it important enough to
let anyone configure it back to the old, broken and confusing method.

I know I can cause something like you're seeing if the first line is from a
normally-nstalled server and the second is from on which was running
chroot'd prior to executing the daemon (or used the  chroot command-line
swithc).  Both of which are such rare cases, I'm probably confusing things
by even mentioning them. :P

 I don't have ckconfig file anymore because originally installed directory
was deleted, so I use # strings /usr/local/etc/wuftpd | grep ftpaccess
command, as you suggested.

--Question1
How many group I can set up under ftpaccess file under guestgroup?
Is there a limit?  If yes, what is the limit? How many ftpgroup99999 I can
add to ftpaccess file?

# specify which group of users will be treated as "guests".
guestgroup ftpusers ftpgroup1 ftpgroup2 ftpgroup3 ftpgroup4

---Question2
What these errors mean?  Any hints?
How can I debug them and fix them?
Server still starts without ftpaccess file but guestgroup rules are applied.
I re-start  /usr/sbin/inetd -s but without the result.

# strings /usr/sbin/in.ftpd | grep ftpaccess

Thanks Gregory. I did try to make sure to look for such before I sent in
my patch, but I very plainly missed the official patch. :-(

Hrmmm... I don't see it, though I realize I should take your word for
it. :-)

If you're talking about the strcpy in mapping_getcwd, isn't the path
passed to that declared as an array of MAXPATHLEN (or was that the one
that's MAXPATHLEN + 1?) before the call?

Again thanks. I'm sorry I missed that earlier.

I have a couple of questions about the throughput limiting implementation of
wu-ftpd. First off the way it appears to work to me so far is that when a
person logs on it checks where they're from (domain/IP addr) and limits them
accordingly. I have been doing it this way and it has been adequate for now,
but what I would like to do is:

A. Limit per class, instead of per address
B. One large b/w pool, instead of per instance of ftpd

What I mean is, lets say I have a class of users called ftp1, I would like
to limit them to 20K/s speeds. But instead of each logged in user getting
the limitation, the whole class gets limited and they share the 20K/s I
specified in the ftpaccess file.

Anyone have any thoughts on the idea?

Don't hold your breath.  This is something which _might_ be doable in
version 3, if/when we get going on it.

Edit this.  *.domain and 0.0.0.0 should be replaced; or just remove the
entire line and and 'class local' stuff like the limit below.

You probably don't use this.  Omit it or say 'private no'

Do you really want anonymous overwrite, delete and rename?  It's VERY
dangerous.

These only apply to users whose home directory is '/var/ftp', probably the
anonymous user.  Guest are, therefore, 'upload * * yes dirs'

I keep coming back to inetd not passing the parameters to the daemon.
That's the only reason I can see for it not using ftpaccess.  No -a switch
and no use ftpaccess.

Here's how I'd test for ftpaccess being used:

Check the manpage, do you have 'hostname' or 'greeting'?  If so, use one of
these and see if the greeting when you connect to the server changes:

hostname it.worked
greeting brief

If so, take them out.  Your ftpaccess file is being users.

If you don't have these features (an academ version), comment out all
'class' statements.  You shouldn't be allowed in: no class.


The problem is almost always inetd.conf if the ftpaccess file isn't being
used.

Hi Gregory,
=20
 I was looking through my partitions for 'wu-ftp*' and the only thing I =
found,
next to the files I've downloaded, was a directory
'/usr/doc/wu-ftpd-2.4.2vr17' with no executables.  My inetd.conf shows =
one
line for ftp as follows:
=20
 ftp  stream  tcp  nowait  root  /usr/sbin/tcpd  in.ftpd -l -a
=20
 but no reference to wu-ftpd.
=20
 I am confused I guess, because I don't know how to tell what ftpd I am =
using.
I thought it was wf-ftpd but now I just don't know.  If I install the
wu-ftpd-2.4* package and I'm not running wu-ftpd, won't that cause =
access
problems?
=20
 What steps would you recommend I take at this point to get 2.5 =
installed and
running?
=20
 Thanks for your help...

wu-ftpd usually installs as the same name as the original ftp daemon for
your system.  that's because the original concept was to be a dropin
replacement.

connect to the server.  the greeting (usually) will tell you the version.
If it doesn't you're probably running wu-ftpd, but you can check by logging
in and issuing
  quote stat
the status report will always have the version number

btw, your inetd.conf is an example of a improperly formatted line.  you're
using tcp wrappers, so you need in.ftpd stated TWICE:

ftp stream tcp nowait root /usr/sbin/tcpd in.ftpd in.ftpd -l -a

Both worked great!  Thanks again.

Ok, I understand adding it twice - but why?  I don't understand what tcp
wrappers are or a working knowledge of what in.ftpd is or how it basically
works.  Could you, at your leasure, expand on them?

> download 2.5.0 and the patches, patch and build fresh.

Will do.  I downloaded 2.5.0 after our first e-mail exchange and will go get
the patches today.

Thanks again for your expert assistance.  I particularly appreciate your
ability to explain things so I can understand them.

Have a supper weekend my friend...

Ron

How can I run wu-ftpd on several IP address of a machine? I have a machine
that has five IPs on it, and I'ld like the daemon to run on only four of
those.

By reading the FAQ and the man pages I can not figure out how to do this. By
default wu-ftpd runs on all addresses of a machine; I see that I can use the
daemonaddress ftpaccesses parameter to set the daemon to run on only one
address. Neither of these settings work for me.

Any help would be much appreciated..

You only _appear_ to be giving the name twice.  Actually, the first
parameter is the name of the FILE.  The second is the name by which you
want the program to _think_ it was called.

This can be important to programs like Sendmail which behave differently
depending upon the name the program _thinks_ it was executed as.

In C programming terms: the first argument to TCPwrappers is the name of
the executable file.  The following arguments are the argv strings to be
passed to the programs.  The first argv value (argv[0] to the C program) is
the name under which the program _thinks_ it was executed and is required.

So your command line said, "Run in.ftpd, but let the program think it is
named '-L' and pass it the parameter '-a'."

You never noticed the -L wasn't working and your ftpaccess file was being
used because the '-a' was still being passed in.

If you'd have done the options the other way arround, you'd have posted a
question (see the FAQ), "I have -a on the command line and the daemon isn't
using my ftpaccess file.  What's wrong?"

In a word: xinetd.

The daemonaddress parameter is there to tell the _standalone_mode_ daemon
to use ONE address.  I put it in because I needed it for a specific
configuration.

	I have a fat32 drive mounted in linux and would like users to be able to
upload and download to it. Also it would be nice if the users could only
browse around in that one drive and nothing else. Any idea how I would do this?

2.4.2 is old.  The current version is 2.5.0 (plus patches).  You should
upgrade.

To your specific problem: more information would help.  IS it only some web
browsers?   What about normal ftp clients?  Does it work on the localhost?
What about other hosts on your LAN?

The FAQ might help.  Please look through it before following up.

No.  What you need is to get something writeen in, say, the last decade.
The current version is 2.5.0 (with patches).  Get it.  Version 2.4 has so
many security problems, I'd suggest the failure to compile is a godsend; at
least it stopped you from making a monsterous mistake.

In the current version of wu-ftp the umask of the directories is set as a
default to the mask of the user who has access the server. We have need for
the directory permissions to be different. The ftpaccess man page says that
this is possible using the <d_word>. 

Okay, I gather that this must be something done during the compile. I wish
is was in the ftpaccess file. What do I change and in what file during the
compile to do this?

The source files.  Try using the 2.5.0 version, and grab the patches while
you're at it.

The _read_ the upload.configuration.HOWTO.

I'm attempting to upgrade in response to the recent announcements about
holes in older versions.  Is the answer for those of us running 4.1.3
basicly that we are SOL ?

The problem: I've gotten it to compile, but I can't 'get' any files.
Apparently, it's looking for files in whatever dirrectory ls is run from.

I've checked through the the mailing list archive and the FAQ, and found no
mention of this. If it has been brought up I will happily take a pointer.

I'm assuming this as to do with the getwd/getcwd problem. For now I've
compiled it with getwd, simply commenting out the #error line. 

Is this a known problem, has someone already solved this, or am I just doing
something dumb ?

Our "guest" community under wu-ftpd-2.4.2/2.5.0 (Tru64 UNIX v4.0D) is
composed of two distinct subcommunities. We'd like to give these subcommunities
different sets of privileges, specifically to have one subcommunity be able 
to use "rename", and the other not. 

How do we set this up? Should I have two guestgroups? What would the 
"rename" clause for the two subgroups look like? What other statements
would be diff. than the standard config? Here's our ftpaccess right
now:

The glib.wtmp patch for 2.5.0 isn't going smoothly for me.  Instead of just 
applying, I get prompted for "File to patch:".  What am I doing 
wrong?  Here's the output:

Okay, I've read the howto ... and it says to use the defumask to define
rights not disallowed in the upload section. Pretty much everything we can
think of is defined, except directory creation. I added a 'defumask 000
testgroup' to my ftpaccess. When I log on to the system using a ftp client,
it creates the directories with the access d---r-x--- rights. So the
directory is created, but no one else can use the directory. 

Basically, a user needs to create a directory for a client, who then can ftp
to the site, with a different class definition, and can change to the
directory and get the files. What am I missing here?

No, the 2.5.0 daemon should work acceptably well on your server.

Never heard anything like this before.  The only thing which comes to mind
is a guess: try using an ftp client instead of a web browser: does that
make a difference?

Maybe, but I'd have to see what is happening.

Yes, yes, and .. well .. maybe.

There's a file, getcwd.c, in the support area, which implementes a portable
getcwd() function for systems which don't have one.  The best thing to do
is to use that function.  That way, the monsterous security deficiency of
your operating system can be overcome, and a more-secure FTP site provided.
The rest of your services are potentially still in-secure, but at least FTP
will be protected from a lot of buffer overruns).

There's a note about this in the ERRATA.  Also, someone has alrady done a
SunOS port fixup for getcwd(), which will appear in 2.6.0 .. I don't recall
if he did anything more than cause the file to be compiled and linked with
the daemon .. maybe added a header.

Caveat: it's been a while since I played with this, so it may be a little
flaky.

Yes, create two classes.
Remember the defaults for for 2.5.0 are 'no' for anonymous and 'yes' for
guest and real.

class norename guest !10.0.0.0/8
class canrename guest 10.0.0.0/8
class insecure real *
class anyone anonymous *

guestgroup misc
rename no class=3Dnorename



Don't forget to read the upload.configuration.HOWTO.  This use of class=3D =
is
what the ERRATA is referring to .. it should work as I have it here to get
what you want done.

You're not doing anything wrong.  Somehow the patch got built wrong (it was
already in the src directory).  Just type in src/logwtmp.c and you will be
fine.

Sorry, the patch has been out for a while, and I just noticed the problem a
couple days ago.  I don't like changing a released file, so I've not
updated it to correct the error.

defumask only applies when there is no upload clause.  (thought the Howto
said that .. doesn't it?)

Looks like you have an upload with a directory mode parameter of 050
specified.

Example numbers.  The Class A network 10 (10.*.*.*) is reserved by the IANA
for use by internal LANs and is not routable (unless your ISP is a fool).

What I'm saying here is "noreanme, not internal users", "rename, people from

I'm kind of new to this. Which document would I read about changing the
directory mode parameter?

Our server must be set up to allow our employees to post, but not to be able
to retrieve the files once dropped on the server. They can delete the files.
These files should only be retrievable to the clients.
In the same manner, the clients have to be able to drop files, but not be
able to retrieve these files once dropped on the server. These files should
only be retrievable to the employees.

What we did was to compile two ftp deamons. The employee group drops the
files in the client class, and these files are 'owned' by the clients who
can then retrieve them. Likewise the clients drop files in the employee
class, meaning only employees can retrieve them.

This was working well, as I mentioned in a previous posting, until version
2.4.2 vr 18. At this time, the umask of the system no longer was carried
over to directory creation. Instead, the directory is owned by the wrong
class for us. 

This meant that when an employee created a file, it now is created owned by
the client, as the files are. The employee cannot change directory into the
directory he has just created. Likewise the client.

There must be a was we can do this bi-polar kind of arrangement just using
the ftp access. I've read the howto's and they don't seem to cover this kind
of senario. Suggestions?

Dear all,

I have the following relevant entries in my ftpaccess file:

guestroot /data01
guestgroup guest

/data01/etc/password contains:

guest:x:10000:1001:Guest User:/guest:

/etc/passwd contains:

guest:x:10000:1001:Guest User:/data01/guest

/etc/group contains:

guest::1001:guest

My question is .... When I log in as guess I get chrooted to /data01 and my
initial directory is / (the chrooted /).  What I want is for my initial
directory to be /guest (chrooted), and if possible, restricted that
directory and it's subdirs.

Could anyone point out what changes I should make?

I assume that I will need to make use of the restricted gid command in
order to accomplish this, but am having no luck on my attempts so far.

Thanks in advance,

James

I have installed wu-ftpd 2.5.0 on an AIX 4.3
the ftpaccess file is used but the commands "get", "put" 
don't work.
I receive the message:

ftp> get index.html
500 Illegal PORT Command

I can just use the cd and pwd command ... I don't understand why ?

Could someone help me ?

Thanks

James,

I've used Michael Brennen's how-to setup a WU-FTP guest account
at ftp://ftp.fni.com/pub/wu-ftpd/guest-howto.

I now have individual "home directories" in which each WU-FTP guest
account is restricted to (and any directories created within it).

The issue I have is that, setting a chroot'd environment on Solaris
implies that I had to add libraries to get ls to run with '-l' option 
and the likes. Setting up guest accounts in this way, would require
to setup chrooted environments for each account to get the functionality
I want. Short of this, guests can still 'ls' (using the WU-FTP provided
'ls' function) as well as upload/download files to their directory.

I vaguely recall 'lofs' as a potential solution to setting up multiple 
chroot'd environments without duplicating all the files. I haven't
found information to explain how to set this up (anyone on the list?)

Günter.

RTFM.  The map page.  upload.configuration.HOWTO.

You need to be able to determine whather a user is an employee or not.
Require employees to be AT WORK when they are working, and use IP addresses
to classify them.  If you cannot use IP addresses to classify employees,
then wait for 2.6.0 (or use BeroFTPD in the interim) and use two IP
addresses for your server.

Nobody's reported a problem quite like this, so I'm guessing:

You're behind a firewall or NAT.  The IP addresses don't match up.

Hello there,

     I spent some time figuring this out the first time I got this problem.
In /etc/inetd.conf make sure the protocol is tcp not tcp6. AIX v4.3.X uses
IPv6/4 compatible versions of the daemons. You entries in inetd.conf
should look something like this:

ftp     stream  tcp    nowait  root    /usr/sbin/in.ftpd         ftpd -a
#ftp     stream  tcp6    nowait  root    /usr/sbin/ftpd         ftpd

I think I have seen this in the FAQ some where.. Not sure I'll have to look.

Thanks a lot . Your solution works very well
I was surprised because I have upgraded my system from AIX 4.1 and in
this version
of AIX I didn't had this problem !

I am getting constantly this error message:
 
<<425 Can't create data socket (142.148.10.35,20): Address already in use.>>

I am fighting with it for few months by upgrading FTP to the newer version
and changing control files but nothing helps.
Lately I think that because ftpaccess is not started I am getting into this
problem
We do have one machine on which 'DATA Sockect' error never occurs.  Nothing
is really different except server starts with ftpaccess.

Any hints for me?


This is the output of 
strings /usr/sbin/in.ftpd | grep ftpaccess

Isn't it  in.ftpd -a ?
I thought the standard UNIX implementation of FtP server binary should be
represented as in.ftpd. -a?

Please advise.

my string looks like this:
ftp     stream  tcp    nowait  root    /usr/sbin/in.ftpd   in.ftpd -a

Yep, I missed that. that is the problem when you cut and paste
from the system supplied line. You end up missing something. Either
way(in.ftpd -a or ftpd -a) worked but I would use in.ftpd -a to
be correct.


ftp     stream  tcp    nowait  root    /usr/sbin/in.ftpd in.ftpd -a
#ftp     stream  tcp6    nowait  root    /usr/sbin/ftpd  ftpd



Thanx for correcting that error.

Upgrade to 2.5.0

ISTM there was a problem in the daemon (I don't _think_ it was a VR-only
problem, but it might have been) .. the PASV port was binding to the wrong
IP Address.

This looks like a data port .. but maybe it's the same problem.

I'd also look for missing vendor patches, or a bad kernel gen (ie., I can
cause this by not enabling some features in Linux).

If you're looking for vendor patches, use the keyword SO_REUSEADDR which is
the name of the socket option which enables address/port reuse.  If it's
broken, not present, or denied by some security feature, the daemon won't
be able to do PORT-mode data transfers.

 Since then ftp server is closed:

ps -ef | grep ftp shows none of processes.

Any hints how to get server back up and running?
I restarted /usr/sbin/inetd but nothing has been changed.

X-Mailer: exmh version 2.0.2

I asked how to set up 2 guest groups with diff. access, so one group could use
rename, and the other not. I got one useful response from Gregory Lundberg,
setting up different classes. Problem is, I neglected to mention that the
members of these groups come in from all over the country, so there's no
good way to isolate them based on IPs. Is there a way to assign members to
a class or group based on their userids??????

Thanks!

I'd like for the wu-ftpd server to show an alias hostname of the
machine it is running on rather than to display the actual host
name of the machine itself.  Eg., at connect time, it should say,

"220 MyFtpSrvr FTP server ready." instead of
"220 MyHstName FTP server ready."

Ditto at disconnect,
"221-Thank you for using the FTP service on MyFtpSrvr." instead 
of
"221-Thank you for using the FTP service on MyHstName."

I cannot find a way do that via the configuration scripts.  Must
I set up a virtual server to accomplish my goal?  I'd rather not
hack the code in ftpd.c and ftpcmd.c..., perhaps other places.

Thanks  --Stan

Noise.  lastlogs are notoriously unreliable for determining what is
running.  Use ps.

Take a look at your ftpaccess.  Does it name a shutdown file?  Delete that
file.

See?  You lastlog is wrong.

Sounds like you have an older version of the daemon. Upgrade to the latest
version from ftp.wu-ftpd.org (if not for this reason then for security
reasons!).

In which there is a configuration directive

hostname

which will do what you want.

Gregory  Lundberg was helpfull in better defining my problem. Basicly, what
happens is that for two successive DIR commands, the first returns the
actually current directory, but the second returns /bin (or wherever ls is
located).

This he says he recalls as bing a bug in SunOS, which there is a patch to
fix. Unfortunately, he can't recall which patch.  I installed the latest
libc patch last night, and it hasn't helped.

Is there someone out there who went through this that can tell me which
patch I need ?

Thank you very much in advance !

Not in 2.5.0.  It's one of the things I've been thinking about for the
ftpaccess handling rewrite.  Since that's not ready, it won't be in 2.6.0
either.

So, I'd suggest using two IP addresses on the FTP server.  One for
employees and one for non-employees.  Using BeroFTPD or 2.6.0 you should be
able to use one daemon to serve both.  The issue then becomes which groups
are 'guest'.

To be honest, though, if I had a need for this myself, I'd hack the feature
in right now.  I don't, and I'm busy with other things on the daemon, so I
won't be able to do it for a while.  Now .. if YOU want to fiddle with C, I
can point you to the right area of the code and let you peek at what I've
been doning for the rewrite of the ftpaccess handlers.

It was me, secure shell'd into another user's box, debugging the problem on
SunOS with the getcwd() and getwd() functions for a VR upgrade.  The patch
from my work is merged into 2.5.0.

What I did was put in syslog debugging statements for the cwd the daemon
thought was current, and what the OS returned.  I did that before and after
the calls to the external 'ls' function (via popen.c) and littered a few
other paces throughout the daemon.  By walking them arround, I was able to
find which getcwd() function was causing the true working directory to be
changed.

OK - from our e-mail yesterday, it sounded like you were talking about
the actual updates to Sunos from Sun --as in an OS problem.

IS this actually merged into the production 2.5.0 out there now, or the
development 2.6 ?

In 2.5.0; 2.6.0 changes it a bit to use the protable getcwd() function.
Actually, ecept for you and the site I was debugging, I've not heard of
this problem; which makes me think it's SunOS version -specific and there
may be some obscure vendor patch for it.

I am running the wuftpd inetl rpm (2.5.0-5.6.0) from rufus.w3.org.

Many messages like login messages and login failures have a few lines
worth of spaces in them for no apparent reason. Has anyone else seen this?
Is this only in the RPM? I can compile it myself if need be. I do not see
this on the version I patched manually on NetBSD (also where I fixed the
segfault on non-existent username bug).

Any ideas, thoughts?

Gregory,

I added the restricted-gid command and am still having the same problems. 
What I log in with user guest, I am chrooted to the base directory
/data01.  It appears that the daemon is not reading the home directory from
/data01/etc/passwd or I have the entry in the wrong form.

I have tried putting the home directory in both absolute and chroot forms
in this file, and neither seem to work.

I just tried using the /data01/./guest syntax in the real /etc/passwd and
managed to get the effect that I am looking for (chroot point of
/data01/guest), but my impression from reading the man pages is that this
shouldn't be necessary.  The relevant man page section from ftpaccess.5 is
included below:

		If a guest-root is  chosen  for  the  user,  the
          user's home directory in the <root-dir>/etc/passwd file
          is used to determine the initial  directory  and  their
          home  directory  in  the system-wide /etc/passwd is not
          used.

As can be seen from the file excerpts included with my original message
(below), the global guest root is set to be /data01 for all guest users
(users in group guest set by "guestgroup guest"), and hence I believe that
the entry in /data01/etc/passwd should then be used to set the home
directory and the user restricted to that directory by restricted-gid.

Perhaps this is a bug, perhaps a feature.

James

Hello all;
  I'm trying to set up daily rotation of wu-ftp's xferlog.
The landfield website shows an example script, processlog, that
does this by
  cat $xferlog >> $newfile
  rm $xferlog
  touch $xferlog
I was under the impression that this was an unsafe approach,
since ftpd keeps xferlog open for relatively long periods
(? at least through each ftp session, if I've understood the code).
So it seems you're likely to either loose entries, or end up
with a log full of \0's
  --- or have I misunderstood something?

Is there a way to setup wu-ftp to pipe xferlog to another program,
as with apache? or some other recommended approach?

Thanks

Try just an 

xferlog=whatever
newfile=xferlog.`$date +"%Y%m%d"`
mv $xferlog $newfile


Assuming that you're moving to the same filesystem... If ftpd has it open it will keep writing until it closes. Then next time it will start a new ferlog file for you. A week or so later (a couple of days?) you can move the oldlogfiles to an archive filesystem, delete them whatever.

Reply-To: bruce.miller@nist.gov@INTERNET

Hello all;
  I'm trying to set up daily rotation of wu-ftp's xferlog.
The landfield website shows an example script, processlog, that
does this by
  cat $xferlog >> $newfile
  rm $xferlog
  touch $xferlog
I was under the impression that this was an unsafe approach,
since ftpd keeps xferlog open for relatively long periods
(? at least through each ftp session, if I've understood the code).
So it seems you're likely to either loose entries, or end up
with a log full of \0's
  --- or have I misunderstood something?

Is there a way to setup wu-ftp to pipe xferlog to another program,
as with apache? or some other recommended approach?

Thanks

I feel that I have been missing some of the list messages, so this is just
a test to see if I get the message back from the list serv, and to see if
other people get it. 

Please don't cc replies to the list-serv in this instance.

Thanks

James
