Subject: wu-ftpd hangs
X-Sun-Charset: US-ASCII
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

Hello everyone,

I compiled wu-ftpd using gcc on solaris 2.5. When I attempt to connect
from another machiene, it hangs after you enter the user name. Below
is the /var/adm/messages entry:

Dec 2 07:14:40 sunfish inetd[128]: config: rstatd/rpc/udp still active and was not reconfigured.
Dec 2 07:14:40 sunfish inetd[128]: config: 100083/rpc/tcp still active and was not reconfigured.

Any ideas?

This error is not related to wu-ftpd.

Anyway, about the passwords.. you could do the following :

telnet to port 21 and then talk the ftp protocol to see what exactly
happens, like

telnet ftphost 21
. message from wu-ftpd
USER xxxxxx
. message
PASS xxxxxx

Maybe one of the reply messages gives more insight.

Tried from the ftp host: "ftp localhost 21"
Then I entered the command "USER username". It gave no message and hung.
The in.ftpd daemon that came with solaris works fine. Also, I rebooted
the machiene and now it does not record messages to /var/adm/messages.
The /etc/inetd.conf entry looks like this:

ftp stream tcp nowait root /etc/ftpd ftpd -l -a

Can you see anything wrong?

Yes. (I took tips from the web site faq at:
<URL:http://www.hvu.nl/~koos/wu-ftpd-faq.html> )

I'm running 10.10. There was a lot more to it that installing the patch
recommended in the faq. I used gcc/bison to build and ran into several
problems. I'll be happy to share my changes, or, if everything built for
and you have just the trusted password problem, try the patch in the FAQ.
It worked for me w/o a hitch.

Chuck Davis

you need those two requirements
- RFC959
- and a coffee pot 8)

Also Stevens W. Richard books
are very good(excellent) and less dry than a RFC.

I am commenting on the post below. Concerning command logging with
wu-ftpd, I found that it is done through the syslog daemon, under
facility DAEMON, severity INFO. To log commands to a file, specify
something like

daemon.info : /var/adm/ftpcommandlog

in your syslog.conf file. See your syslog.conf man page for more
info.

BTW, it would be nice if wu-ftpd could be configured to use one of the
LOCAL{0-7} facilities instead of DAEMON -- other daemons might produce
output of severity INFO to the file specified above.

For log, there's a ftpaccess directive ``log''
see ftpaccess(5).
You can enable it on the command line with
`-L' uppercase `L'.
see ftpd(8).
It's less flexible than the ``log'' directive
of ftpaccess because only command logging is on.

[...previous posting deleted..]

Right, but I think you could achieve this by redefining the facility
in config.h... something like

/*
* login goes to this facility now
*
*/
#define FACILITY LOG_LOCAL3

Thanks for the tip. I was able to compile it and get it to work by installing

Subject: how I built wuftpd under hpux 10.20

Below, is a fairly detailed diff of what I did to build
wu-ftpd-2.4.2-beta-11 under hp/ux 10.20 with the HP ANSI C compiler.

Because I was making so many configuration changes I made a new set of
files ".cus" (for custom), parallel to the .hpx files.

I generally followed the FAQ for the bigcrypt patch, but adapted it a bit
to this version of the code, and _tryed_ to confirm the right value for
some of the defines.

Some of the diffs like the binary installation directory, and CMASK
represent purely local options, so this shouldn't be followed blindly. It
also hasn't been used in full production, yet, so there could be bugs.

I just make a working case.
My /etc/default/init contain TIMEINFO=ROC
Just run following step:
1. mkdir ~ftp/etc/default
2. cp /etc/default/init ~ftp/etc/default
3. mkdir ~ftp/usr/share/lib/zoneinfo
4. cp /usr/share/lib/zoneinfo/ROC ~ftp/usr/share/lib/zoneinfo

I need to compile wu-ftpd-2.4 under Solaris 2.5.1. I need to set it
because of it's extra security and logging capabilities. I have access
to do it on machines that have the gcc compiler or SparcWorks (?) C
compiler for Solaris.

Two of the more major problems are:
vers.c will not compile and I get an error about NGROUPS_MAX not being
defined.
(there are other problems besides these, but these seem the most fatal)

I am *not* a programmer, but can generally get 8 out of 10 programs to
compile by tweaking the Makefile and following directions, and am very
familiar with Solaris and SunOS. But this has me stumped.

I need to have this up and going by Friday night, so any and all help is
greatly appreciated.

Subject: WUFTPD not receiving TZ setting from inetd?
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

Dear WUFTPD'ers,

Two questions concerning WUFTPD.

Has anyone built WUFTPD to run on any flavor of SGI machine?
If so could you please contact me to let me know if your WUFTPD uses GMT
or your proper timezone when writing to log files.

Second question is if anyone more familiar with WUFTPD can shed any
light on the following strange behaviour I am seeing. This happens to be
with WUFTPD 2.4 and IRIX 6.2 but is really a more general question.
I have checked that inetd does have TZ set in its environment to EST5EDT
which is correct. But when WUFTPD writes out to its log file or the system
log it uses GMT (5 hours ahead of EST). I checked in the code and
WUFTPD is making a localtime (ctime(3c)) call which uses the value of
TZ to adjust the current time. So it appears that TZ is somehow getting
unset in the environment? This supposition is further supported when the
/bin/ls -l command is run by WUFTPD. It also prints out times in GMT.
I replaced it with a dummy file and found that TZ is not set in the
environment that it receives. So this would explain the behavior I am
seeing. So then the question becomes if inetd has TZ set and I have
confirmed it passes it to processes it starts from inetd.conf, why doesnt
WUFTPD or /bin/ls have it set in their environments when they are
executed?? I built this version of WUFTPD with all standard settings.
It works great in all areas except for its timezone usage.

Anyone have any input or suggestions at all??????

Thanx,
Roger Hanke

I don't use SGI boxes, but I did see a problem with timezones under
Solaris 2 on my server - but only with anonymous users.

As far as I can tell, the localtime call used needs to access the timezone
information on disk in order to make the adjustment. Under Solaris, this
resides in the /etc/default directory, and so a copy of this (just the
relevant files, not the whole directory) needed to be put under the
anonymous FTP root area, in order that FTP could find it when running
anonymously.

If you only see the timezone problem when logging in anonymously, then my
guess is that IRIX is similar, and you'll need to find your timezone files
and replicate the structure under the FTP root area. If you don't see the
problem when logged in as a real user, then this is probably not the cause
of the problem, and I hope you get a response from an IRIX expert...

I hope this helps !

Cheers, Bob

virtual 123.123.123.123 banner /export/home/tmpt/banner This inables
me from logging in via ftp completely. If I replace it with,
virtual 123.123.123.123 banner /export/home/tmpt I'm able to login but
of course am unable to see the banner. I have the banner in the virtual
root directory. What I'm I doing wrong? My client is pushing me to have
this up yesterday, any help would be greatly appreciated. Thanks.

As I have previously posted, this isn't quite true (at least for Solaris 2.4
and 2.5). What is critical is that the file usr/share/lib/zoneinfo/US/Eastern
(or whatever file corresponds to the setting of TZ in /etc/default/init) be
present in your anonymous area. There need not be a copy of /etc/default/init
in your anonymous area. The TZ information is passed to the ftpd daemon by
means of the TZ environment variable which is init gets at boot time from
/etc/default/init. I am running fine without a /etc/default/init file or
/etc/default directory in my anonymous area.

I am using wu-2.4.2-academ[BETA-11] on an IBM RS/6000 running AIX 4.1.4.

I have someone trying to access my ftp site from a dialup IP site:
PORT-21-MAX-BTV-03.ramp.together.net
When ftpd starts, it says:
ACCESS DENIED (not in any class) TO \
PORT-21-MAX-BTV-03.ramp.together [207.41.55.21]
FTP LOGIN REFUSED (access denied) FROM \
PORT-21-MAX-BTV-03.ramp.together [207.41.55.21], Sgmsw
Note the loss of the `.net'.

In ftpaccess, I had to change:
class local ... ... *.ramp.together.net
to:
class local ... ... *.ramp.together
to work around this, but this is not general nor elegant.

I do not have a patch (yet), but thought you all would like to know.

Well it looks like MAXHOSTNAMELEN is not defined !! ;-)
Usually on Solaris it's defined in

/usr/include/netdb.h
Unless you destroy it by installing BIND

To remedy you can add to ftpd.c
#define MAXHOSTNAMELEN 256

or get the latest beta release of wu-ftpd. The problem
is fixed.

You can get the beta release on .... ???
wait let me get `Michael Brennen' email !!
Damn deleted !! Well it's in the FAQ somewhere...
Don't ask me where's the FAQ :(

BTW I would not do step 4, leave the OS headers
alone.

Anyone with some insight, similar experiences and suggestions, all input
would be appreciated. I have my archive configured the way I need and I
know that it operates correctly since I have tested it using the default
in.ftpd that comes with sunOS 4.1.3. The problem is implementing wu-ftpd.
I compiled it without a hitch and added it to inetd.conf, problem occurs
when I try to connect. My banner displays properly followed by the login
prompt. No matter what name I enter, real user or anonymous, it crashes
before it reaches the password prompt. The error I get from ftp is
"Service not available" the error I get in the logs is signal 11 or
Segmentation Violation error. I have found very little info regarding
sunOS 4.1.3 and WU-FTPD, so any insight would be appreciated and can be
sent directly to me at [email protected].

I've seen this kind of thing quite a bit with clients like WS_FTP and
CuteFTP. Sometimes forcing the server type to UNIX standard instead of
Auto Detect (in the client) will alleviate the problem. I hope that helps.

Subject: ftpgroups and /etc/group
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

Version: wu-ftpd-2.4.2-beta-11

The ftpaccess(5) manual page describes the usage for setting up group
access using "private yes". It says the "real_group_name" is the name
of a valid group listed in /etc/group. I have tested this and found
it to work using the system's /etc/group file.

Question: Is there a way to change the wu-ftpd so that it accesses the
file ~ftp/etc/group instead of the real /etc/group file?

Question #2: Did past versions of wu-ftpd use the ~ftp/etc/group
file for group access?

Peace,
Sam

Anthony,

When you ftp the the platform (solaris 2.5) which is running wu-ftpd,
it promps you for a user name. After that it hangs. It only does this
when the /etc/ftpaccess file is used. No messages are logged anywhere.
I have tried both the -L and -l switches. I have even tried -d. Nothing.
I'm stumped.

Clyde

A "generic" problem to beware of is that many (all?) implementations
of inetd silently drop command line arguments after some small
number (4 or 5?). (In this context, the fact I was running tcpd/tcp_wrappers
may have counted for an extra argument.)

I wrote a c wrapper program to exec the wuftopd to get around this:
= =
/* wrapper for wuftpd to add command line arguments
that don't fit under inetd */

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <errno.h>
#include <syslog.h>

int main(argc,argv)
int argc;
char **argv;
{
char *path="/local-adm/bin/ftpd";
char *cmd="ftpd";

fflush(stderr);
fflush(stdout);
errno=0;
execl(path,cmd,"-a","-l","-L","-u022",NULL);

openlog("wrapftpd",LOG_PID, LOG_LOCAL6);
syslog(LOG_WARNING,(const char *)strerror(errno));
closelog();
exit(EXIT_FAILURE);

}
= =

Season to taste ;)

In ftpaccess you can put the following for the later versions of the beta
wu-ftpd:

noretrieve /etc/passwd core /etc/ /bin/

You should remove all user account info from the password and group files
in both anonymous and guest accounts. Give at least ~/etc and ~/bin
accounts permissions of 0111 so they cannot see the contents, though per
se that may be worth little since most will know the file names they are
looking for.

See also <http://www.iss.net> for more anon ftp security docs.

I don't know tha background to your problem but this may be worth a mention.
My wu-ftp stopped everyone logging in once because my ftphosts file
was longer than the maximum allowed ( 100 lines by default for wuftp 2.4 )
Maybe this is your case. Maybe the same limit applies to the ftpaccess file
as well ? Also what errors are shown in /var/adm/messages when access is
denied ?

Alex,

I am having the same problem. With me, it is when I use the /etc/ftpaccess
file. When I give ftpd the -A switch (which tells ftpd not to use the
/etc/ftpaccess file) everything works fine. Of course, without the use
of the /etc/ftpaccess file, it is just like normal ftp daemons. If anyone
has any ideas, please let me know.

I have a script to go through the /etc/passwd file, strip all passwords
and information from the entries (get it down to username, uid, gid ...)
and throw that into the /etc directory off of the ftp server... I've
since stopped using it since it gives outsiders a list of users on my
system. Now the password file on the ftp server has all the normal UNIX
users listed (all passwords are '*'), and then a fake user as the UID/GID
that adds things to the public FTP section.

If a user logs in, they're not chroot'ed, so the ftp server uses the
system-wide password/group files, so nothing's affected whether you come
in through anonymous or user mode...

Just my two cents worth. 8)

I added in the ftpaccess file the following:
noretrieve /etc/passwd /etc/group /etc/nsswitch.conf /etc/netconfig core

This makes the designated files non-downloadable , so any files you do not
want to be downloaded should be given a noretrieve entry.

The only thing I keep in my ~ftp/etc/passwd file is:

ftp:*:500:1::/var/tmp:/usr/bin/false

I don't understand why it's necessary to have other accounts in the ftp
passwd file(?). I have ftp-only users but these are of the chrooted
variety (shell = /bin/false, login dir = /ftphome/./user) and their entries
are in the regular passwd file. I haven't had any trouble w/ this config
*yet*. ~Please~ don't try. :)

As for hacking the system, monitor the logs. In the case of using real
accounts, 'lastb -R' is handy. (On the system here the -R shows where the
login failure originated.) I check these on a daily basis. There are many
other checks to you can make.

Take a look at ftp.win.tue.nl/pub/security. Last time I looked there was
an excellent document about improving your security by breaking into to it.
Plus there are numerous tools. There are also quite a few books (check
O'Reilly books at www.ora.com) on the subject. Or do a web search on
computer/security...

Chuck Davis

Someone was poking around my system tonight. They grabbed a copy of
/etc/group /etc/passwd and /etc/netconfig inside the ftp directory.
This made me wonder just what information ought to be in those files.
As it stood I had some usernames in the passwd and group file. There
were no encryped passwords though this gives me little peace of mind.
Just what do people do to make wu-ftp as secure as possible? Are there
a list of tips? Finally, once you get a poker doing this, what steps
should be taken to keep the person who obtained real user names from
hacking the system.

TIA,

I located the CMU version of ftpd recently... it's based upon an
earlier version of 2.4.2; I wonder if anyone has merged the code
changes to support kerberos into the latest beta.11 distribution.

Have concrete plans been made to support kerberos-5 in 2.5 (or has
anyone started on this)?

It couldn't be as simple as /etc/shutmsg could it?

Check /etc/ftpaccess for

shutdown /etc/shutmsg

and check to see if said file exists.

First thing you do is contact their ISP and anyone else they are connected
with. What you have is someone who is not only a willing hacker, but an
ACTIVE hacker. ISP's don't like those kind of people because who know's
who they will hack next. I've had three different attempts at our site,
one turned out to be an employee who got fired on the spot for it. The
other two lost their internet access rights with their ISP.

I'm still trying to figure out everything that goes along with being our
internet site manager but we rely on our firewall a lot. Despite this, I
monitor the log files to see what's happening on our site.

That's about the best I can do for now to help out. I've seen references
to O'Reilly books a lot and I'm sure they have one on system security.
Might check that out.

I just installed wu-ftp 2.4 under Solaris 2.5.1.

Everything appears to be working, except that the 'dir' command
displays uid/gid numbers instead of user/group names.

The uid/gid in question are in the stripped versions of passwd &
group in ~ftp/etc. I don't have private groups set up (at this
point). Permissions are:

The absolute *best* book on Internet Security I have found is:

_Firewalls and Internet Security_
William R. Cheswick & Steven M. Bellovin
Addison-Wesley
ISBN: 0-201-63357-4

The O'Reilly's are OK, but the Cheswick and Bellovin is by far the best:

_Practical UNIX Security_
Simson Garfinkel and Gene Spafford
O'Reilly & Associates, Inc.
ISBN: 0-937175-72-2

_Managing Internet Information Services_
O'Reilly & Associates, Inc.
ISBN: 1-56592-062-7

Different systems may vary.

On my Linux system, anonymous ftp logins are accessible from `last'. The
`w' and `who' and `finger' commands only display users using a tty, which
ftp users do not.

Isn't there an `ftpwho' program included with wu-ftpd?

I am installing wu-ftp2.4 on an AIX4.4 system; all seems well except
that
I notice that timestamps of the ftp log are 8 hours ahead; ie, GMT.

Anyone who can advise me on how wu-ftpd can reset its time from GMT in
an AIX system please inform me,

Thanks

X-Mailer: Microsoft Exchange Server Internet Mail Connector Version 4.0.993.5

Hello...

I do not think this has been asked before...read on......
using wu-ftpd 2.4.2 beta 11
linux 2.0.2x (currently 2.0.27)
This is the directory structure:

/regular_stuff
/home
/home/company_name
/home/company_name/user1_dir
/home/company_name/user2_dir
^ chroot()
/home/company_name/virtual_html_dir
/home/company_name/virtual_ftp_dir
/home/company_name/virtual_ftp_dir/usual_stuff
^ chroot()

The virtual ftp stuff works for the virtual ip. The user chroot() works
for the real ip.
The user chroot() does not work on the virtual ip.

It seems that the wu-ftpd senses that the connection is coming in on a
virtual ip address and does the chroot() at
"/home/company_name/virtual_ftp_dir" before checking if the logon name
is a real user. If the logon name is a real user then the chroot()
should be at "/home/company_name" . But it is too late, the "chroot()
ing" is already done and is not re-configured. After the connection is
accepted all the user can "see" is the files in
"/home/company_name/virtual_ftp_dir" . I think the logic would go
something like this but, I am not very much of programmer and something
like this is beyond my abilities.

accept incoming connection
if on virtual ip then chroot()
accept authentication
if authentication is not anon and a valid user then re-chroot()
<--this is the part to be added
continue with connection

Any help with this situation would be great.

You're right. This is exactly how it works.

Personally, I went in to the wu-ftpd source and changed that. If it's a
real user, I don't think it should chroot at all - except for the usual
"guest" users. I think the guest user chroot solves the problem sufficiently.

Here is my patch to Beta-11 for this. Basically it just moves the check for
anonymous before the virtual root is set.

You've got to copy one of 4 libs to ~ftp/usr/lib according to the
name resolving system you use. Those libs are:
/usr/lib/nss_dns.so.1
/usr/lib/nss_files.so.1
/usr/lib/nss_nis.so.1
/usr/lib/nss_nisplus.so.1

I was getting fairly confused reading the documentation trying to figure
out which files needed to be mirrored for chroot and which not, so I
finally created a directory:

~ftp/etc/ftpmsgs

and I created a soft link in the real /etc directory to it.

I then put all my message, banner, and shutdown files in this directory,
referring to them by the path /etc/ftpmsgs/something

No problems, no mess.

Symbolic links can be useful if you remember that they can point from the
real file system into the chroot ftp directories, but not vis-versa.

Another tip. To avoid creating writable files at all, set umask 0222, then
use vi and the ":w!" command to update files.

(very bad choice of subject in my not very humble opinion, but to keep up
the thread).

Quoting James Sneeringer, who wrote :

There is, which works perfectly, *IF* :

- ftpd is started with the -a parameter
- the directory for the pids-files exists
- And is writable for root (ie : not NFS mounted)

On ftp.cetis.hvu.nl, a Linux system, ftpcount and ftpwho work nicely and
I even use ftpcount in the screen with tourist information.

Sophisticated manner : get ncftp so you can type

ncftp ftp.site.name:/path/to/file

Or store all commands for ftp in a script so you can type :
ftp sitename < script

This one could have some problems due to command buffer clearing.

Anyone out there get 'zip' and 'unzip' to work on a sunOS 4.1.3 platform?
I've made all the appropriate entries in the ftpconversions file and the
binaries in ~ftp/bin do work outside of ftp. Would be real nice to be able
to support (un)zip from ftp.
(un)compress and g(un)zip work just fine, can't seem to get (un)zip to work.
Is it even supported?

I still seem to be stuck on this problem, I tried everything I was advised
to do... but everytime I tried to login it gives me a access denied prompt
for everyone including anon. I dont know, to me it seems that it doesnt
read the ftpaccess file, and I do have the ftpd -a on...

Hello everyone!

I am writing (more improving) a PD ftp client.
Some time ago I thoght I found a 'bug' in some versions of wu-ftp.

Now as I had time I downloaded and installed wu-ftp BETA-11 on my
system and can confirm that it was no bug in the ftpd code as it
simply works on my system as it should and fails on always the
same server systems in the same manner.

However it seems to be a bug in eighter a certain compiler or
widely used operating system or it is some other weird
interaction or setup that is used on lots of sites,
I am definitely not sure.

Is there a way to test this with a standard client like
ncftp or so? I can't get quote to use a port, just simple
commands like PWD work for me with quote. How can I do a
RESTART with any commandline client?

Sites that I know that behave 'buggy' are (all using wu-ftpd):

ftp.wustl.edu
ftp.evolution.com (System V-R4)
ftp.peanuts.leo.org (HP-UX)
..

I would be wondering if it is possible to discover a pattern
of OS's or compilers used. Maybe wu-ftp just works if

Thanks for any suggestions,
Cat.

The sequence (PORT commands removed to make it simple):

> CWD /packages/graphics/image-tool
> RETR it125d1.zip
< 150 Opening BINARY mode data connection ...
> ABOR
< 426 Transfer aborted. Data connection closed.
< 226 Abort successful

[ everything works here ]

> NLST -laL
..
< 226 Transfer complete.

> REST 70656
< 350 Restarting at 70656. Send STORE or RETRIEVE to ...
> RETR it125d1.zip
< 150 Opening BINARY mode data connection for ...
> ABOR

[ fail to abort ftp here - it gets simply ignored ]

What error messages do you get in /var/adm/messages ?
Do you have an ftphosts file and an ftpusers file ?
What do they say ?
What about any deny commands in ftpaccess ?

Subject: Ftpds that don't die...
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

I have a number of ftpds that aren't dying. The oldest on Dec 8 is:

4706 0.0 0.8 2236 980 ? S Nov 13 0:00 in.ftpd -a

There are about 10 of them spread over the last month. This is with version
2.4.2-beta-11. Is there a known bug in beta11 that leaves an
occasional stray ftpd every few days, and a patch? Or a beta12?

Thanks!

Hi, everybody,

I 've tried to install wu-ftpd these last days, insuccessfully on aix on
risc/6000 E20.

I've followed the steps of the file Installation Instructions,
i've read the faq, and some messages of this mailling-list, but i've not
found the solution to my problem.

I've had the messages about strunames, typenames, ... and i've installed
support/ftp.h, but now the building is giving me message about cmdtab,
sitetab, ... undeclared.

Below, the message i've got, when i proceed to build aix.

I've a tiny patch below that has eliminated most of the hung ftpds for me.
I'm still getting a few if an upload is cancelled, but I haven't chased
those down; they haven't become that much of a nuisance yet.

This is not original with me; in desperation I adapted it from some older
patches. As written, it very significantly reduces the number of hung
ftpds.

I suppose the 120 seconds might be short, but if I haven't gotten
*something* in two minutes I figure it is probably worth canning. What
would you suggest for a value?

Or you could use Jeffrey Friedl's webget, which can pull from both both

Subject: unsetting SETPROCTITLE
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

Dear WUFTPD'ers,

I was forced to undefine SETPROCTITLE in order to get my SGI IRIX 6.2
version to use timezone info correctly. Now I am left with the question of
what exactly am I missing in my SGI version due to this undef?

When the no set process title version is run the ps entry does not appear
that different from when it was set or from the standard ftpd entry. Below
are the entries, where the sgi version has it unset, the standard external
version has it set, and the final entry is the official SGI daemon:
rahdev 10909 250 71 Dec 05 ? 5639:35 sgi.wuftpd -d -l -L -u007
rahdev 9144 250 0 16:57:17 ? 0:00 ext.wuftpd -d -l -L -u007
rah 9256 250 0 17:04:46 ? 0:00 ftpd -l
Here are the corresponding lines from the Solaris external version built
with set process title defined and the standard Solaris ftpd version:
root 8335 489 15 16:57:05 ? 0:00 ext.wuftpd -d -l -L
root 8911 489 14 17:05:30 ? 0:00 in.ftpd

So does anyone understand all those SETPROCTITLE lines of code
enough to summarize what value add I am missing out on?
Thanx,
Roger Hanke

Dear fellow users/admins of wu-ftpd,

I have been on this list for a while and I think that I have seen
quite a few patches on it since Beta-11 came out. Some of the patches were
fixing bugs to the core functionnality of wu-ftpd, others were extending
the functionnality.. most of them would be nice to have in the future
release of wu-ftpd. Do people who issue those patches send them all by
mail _also_ to Stan Barber ([email protected])? Is stan still
working on a future release of wu-ftpd incorporating some of these
patches? That would be very nice if all these efforts could be coordinated
and incorporated into the next release. Forgive me if this question has
been asked recently but I was just wondering...

PS: Just in case.. I usually archive most patches sent to the list, in
case someone (Stan?) missed some and needs them to add to a new release..

hmmm, it must depend on your OS platform. I'm using HP-UX 10.10. When
using SETPROCTITLE I get this:

ftper 26561 607 0 20:48:23 ? 0:00 wuftpd eod.nasa.gov: connected: IDLE

The ftpd that was shipped w/ the os was only slightly more informative:

root 26882 607 0 20:57:39 ? 0:00 ftpd eod.nasa.gov: anonymous/cdavis@: TYPE I
When undefining SETPROCTITLE wu-ftpd gives this:

ftper 26852 607 0 20:52:26 ? 0:00 ftpd -a -l

Not very informative but at least it fits in under 80 columns!

Hi,

I am using wu-ftpd-2.4.2-beta-11 on BSD/OS 2.1. I noticed that some ftp
sessions are idle but are not closed so they disallow new connections. I
believed that beta11 solved this bug. How to kill those connections
automatically ? Is it possible to use the output of ftpwho ?

Here is the ftpwho output I got :

Service class remote:

- 6 users ( 10 maximum)

Furthermore, there is no explanation in manual pages about the output of
'ftpwho'.

Thanks in advance for your help. Gildas.

X-Mailer: Windows Eudora Pro Version 3.0.1 beta 3 (32)

i have a "big" problem with links...

wu-ftpd 2.4.2b10
linux 1.2.13

for all users's $HOME i would like to have:
- a link to the public sofware (so they do one connection and
can go in they $HOME and in the public path)
- a "incoming" link tu upload ME what they whant

first here is my filesystem:
#df
/dev/hda2 /
/dev/hda1 /files
/dev/hdb1 /disk2

-> my users and ftp home are in /home/xxxx (on /dev/hda2)
-> my public directory is under /disk2/public (on /dev/hdb1)

so in a "one_user" i have:

#ls -l /home/one_user
lrwxrwxrwx 1 root root public -> /disk2/public
lrwxrwxrwx 1 root root incoming -> /disk2/incoming
./..
and other files from the "one_user"

(1) the public directory:
When the user go in the link "public" he can see all the files in it..ok
When the user do "CDUP" or "CD .." he go the the /disk2 not the the
$HOME !!

(2) the Incoming directory:
When the user go the incoming tu upload all is ok i receive the file in
/disk2/incoming
When the user do "CDUP" or "CD .." like the (1) he go to the /disk2 !

i have see in different files about wu-ftpd something about "ls" and the
static options
(my english is not good :-() so i get the GNU fileutils.3.13, compile the
"ls" in static
put it in /home/ftp/bin and in /bin. no success the problem is the same...

so these 2 questions:
- How can i do this with the respect of the public's file on /dev/hdb1
and the users
on /dev/hda2 (is it the problem ??)
- How can i receice all the upload file in ONE directory for real user ?
$HOME is $HOME, i don't whant to go in they house :-)

thank's a lots for any answer or sugestion, but please do it clearly and if
possible with examples..(again..i have a so poor english)

thank's

Thierry LOUVEL.

I would believe that the TZ variable is not set for the ftpd process, which
could be caused by the fact that ftpd is started by inetd which is started
from /etc/rc.tcpip which is started via /etc/inittab by init which hasn't
set this variable in the first place. Try to define TZ appropriately in
rc.tcpip before inetd is launched. If TZ is not passed through startsrc then
you could alternatively call a script in inetd.conf instead of calling ftpd
directly, and in this script first "export TZ=whateveryouneed" and then
"exec ftpd $*".

Hope this helps

Cheers,
Thomas

Subject: wu-ftpd under Solaris 2.5.1, "LIST" -> "Connection refused"

I seem to be suffering an odd problem that I can't quite figure out.

While setting up a chroot'd ftp dir for a customer, I noticed that when
attempting an ls (with various flags... -l, -la, -laR et all) I'd
frequently get "Can't build data connection: Cannot assign requested
address". I don't recall it doing this to me before... but now the
problem even occurs with ftped into my own account, which isn't chrooted
and uses the main system libraries.

This is wu-ftpd 2.4, beta 11, though I pulled down regular 2.4 and built
it to see whether an older version would have the same problem... it does.

The oddness is that the problem is VERY inconsistent... I can type ls
several times and it will work fine... then I can try once more and be
greeted with that error.

After fussing around with the libnss* (as mentioned in a previous thread
about uid/guids not resolving) the ls problem seems somewhat lessened...
but now I CAN consistently cause "Can't build data connection: Connection
refused" with a 'quote LIST' command. Which is odd, since ls now seems
to be working fine. (Yes, I'm trying things even as I type this. :) ).

Has anyone seen this before? The largest difference I can see is that a
call to ls sends an NLST command (I'm probably wrong), as opposed to the
quoted LIST command.

What have I buggered up here? :)

Concerning the post below about automated ftp, I really liked using
ftp.pl (I believe there is a Perl5 module for this now) with Perl for
this. It was really easy and very effective.

Or you could use Jeffrey Friedl's webget, which can pull from both
both
http: and ftp: URL's... It's at either of these sites :-

All,

I am setting up WUFTP 2.4.2 Beta 11 to do virtual FTP servers. I have
compiled the server -DVIRTUAL and added the lines to the ftpaccess to
support the virtual FTP server.

When I try:

ftp domain.com
Connected to domain.com.
220 alpha.comsource.net FTP server (Version wu-2.4.2-academ[BETA-11](7)
Tue Dec 10 10:16:39 CST 1996) ready.
Name (domain.com:asaylor): ftp
331 Guest login ok, send your complete e-mail address as password.
Password:
550 Can't set guest privileges.
Login failed.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp>
ftp> quit
221 Goodbye.

I do see a message in the syslog indicating a VirtualFTP connection but I
dont see any other errors. What does the "error 550: Can't see guest
priviledges" mean? This server is running a non-virtual anonymous server
that is working fine. I duplicated all the needed file structure and
permissions and double checked them. So I dont think its a file permission
problem... what have a missed??!!

TIA All!

That's normal. The door(2) manpage has some (sketchy) information about
what's going on there. Apparently that interface will be documented a
little more completely in 2.6.

John,
Thomas reply only partially covers your problem I suspect.
The FAQ identifies AIX (like SGI) as one of those OS types that dont
support SETPROCTITLE. If this is true it means that your TZ value is
getting munged by wuftpd, even if it is set properly in your environment
(like it was on mine on SGI). So go to src/config/config.aix and undef
SETPROCTITLE. Then do a clean or remove src/config.h so that a new
link is done during the next build invocation.
Disclaimer: I have never, will never, work on AIX ;-)

I would believe that the TZ variable is not set for the ftpd process, which
could be caused by the fact that ftpd is started by inetd which is started
from /etc/rc.tcpip which is started via /etc/inittab by init which hasn't
set this variable in the first place. Try to define TZ appropriately in
rc.tcpip before inetd is launched. If TZ is not passed through startsrc then
you could alternatively call a script in inetd.conf instead of calling ftpd
directly, and in this script first "export TZ=whateveryouneed" and then
"exec ftpd $*".

Hope this helps

Cheers,
Thomas

Running wu-ftpd 2.4 on NeXTSTEP 3.3, using the "guest" mode FTP, that
chroot's the directory to the login directory, ls is not returning a full
directory listing.
What happens is this:
typing "ls" returns the list of files and directories.
typing "dir" returns nothing
typing "ls -al" returns nothing

Basically, I cannot retrieve any extended information such as owner, size
and date.

I am aware that library requirements probably exist, so I'm wondering if
anyone has done this under NeXT? The ldd/truss commands do not seem to
have a NeXT equivalent for determining which libraries ls requires, nor
does NeXT's ftpd man indicate which libraries are required. Neither the
wu-ftpd FAQ, or the guest-howto make any mention of any special NeXT
requirements. If anyone has done this under NeXT, I would appreciate any
suggestions.

Thank You Much,
Matthew

Hmm. I'm running on Solaris 2.5, and I have not copied the
/etc/.name_service_door file across to the FTP root. My guess is your
problem lies elsewhere...

If it isn't a missing dynamic library, the only other thing I can think of
is that you could be missing the relevant entries in the copy of the
etc/group file under your FTP root. I can't be sure, but I think I remember
that you said you'd checked this already ? If you haven't done this, do
so - if you have checked it then I'm stumped for the moment.

The best I can offer right now is to email you a listing of how my
~ftp/usr/lib is set up so that you can see if I have anything there which you
don't... Let me know if you want this, and I'll email direct to save
inflicting it on the rest of the list members.

Cheers, Bob

Subject: Group Controls...

I'm configuring wu-ftp2.4 on a Sun Ultra Sparc station running Solaris
2.5 for group controls.

Anonymous ftp is working...

The chroot ()ed seems to be working...

..in the /etc/passwd:

cabeyou:x:6376:500:wuftp_user:/xxx/yyy/./cabeyou:/bin/sh

..but the commands do not work:

230 User cabeyou logged in. Access restrictions apply.
ftp> pwd
257 "/cabeyou" is current directory.
ftp> ls
200 PORT command successful.
425 Can't create data socket (0.0.0.0,20): Bad file number.
ftp> ls -la
200 PORT command successful.
425 Can't create data socket (0.0.0.0,20): Bad file number.
ftp> put .profile
200 PORT command successful.
425 Can't create data socket (0.0.0.0,20): Bad file number.

Is it necessary to have a ftp structure ( with etc,dev,...) in the
/xxx/yyy directory?

Has anyone seen this before?

I made some modifications to your virtual ftpd support that may interest
you. I have cc'd this note to [email protected], in case it interests
the wu-ftpd developers as well.

Primarily, I allowed for hostnames as well as ip numbers in the ftpaccess
file. I also had the code use the first instance of each "virtual" command in
the ftpaccess file, rather than parsing the whole acl list and using the last
instance.

Also, I removed the code for what must have been the "old way" of handling
virtual domains, since it's not documented anyway.

I added a feature of my own (RESTRICTED_VIRTUAL_ADMIN) which allows remote
administration of a virtual ftp site by a single admin account, which is
restricted to the chroot() environment, and need not have a valid shell (thus
allowing for /bin/false shells to restrict the remote admin to ftp only).

Here's the patch:

I have wu-2.4.2-academ[BETA-11] running under AIX 3.2 and AIX 4.1.4.
It was compiled under 3.2, and I did not have to do anything special
with SETPROCTIILE to get it to compile. My logfiles are in localtime.

When I was using the stock wu-2.4 version, I *did* need to
#undef SETPROCTITLE.

For more details, I have web pages set up for the configurations
of the various software I use. Check out:

when I had that error...it was because I did not have this variable defined
properly ( ie missing directory )

src/pathnames.h:#define _PATH_PIDNAMES "/usr/adm/ftpd/ftp.pids-%s"

Mauricio,
I think...............
you need to put copies of, or links to (use hard links back to the source to
save fs space);
ls in ~<chrooted>/bin (and any other commands you want users to be able to
executed eg gzip tar compress)
& the associated libraries in ~<chrooted>/usr/lib

Note. If /bin and /usr are on a different filesystem then I suggest local
copies to somewhere appropriate on the file system where the chrooted ftp
directory tree lives then hard links from each clients chrooted directory to
the copies.

try executing
truss -f chroot ~<chrooted> /bin/ls 2>&1 >/dev/null | grep open
this will show you all the libraries called by ls
I have...................
-rwxr-xr-x 3 bin bin 107532 Nov 21 14:10 ld.so.1
-rwxr-xr-x 4 bin bin 664048 Oct 28 1995 libc.so.1
-rwxr-xr-x 3 bin bin 2568 Nov 21 14:10 libdl.so.1
-rwxr-xr-x 4 bin bin 15304 Oct 25 1995 libintl.so.1
-rwxr-xr-x 4 bin bin 39340 Oct 25 1995 libw.so.1
but not all are needed

you also need to;

cd ~<chrooted>/dev
mknod zero c x y
mknod tcp c a b

(check /dev/zero and /dev/tcp for the values of x y a b - they are platform
dependent) do not copy them!!!!!!!!!!!!! the device /dev/zero is an infinite
stream of binary zero and will fill your filesystem!

You need to fetch the guest howto below and go over the setup for 'ls' and
friends.

To long time list members, sorry for all the repetition of this standard
stuff; I keep hoping it will sink in.

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

Yes. Every filesystem root needs its dev, etc and lib to work.

Which ones exactly depend on operating system version.

All,

I've followed the instructions for setting up a guestgroup in Michael
Brennen's doc - BUT once I enter the guestgroup in ftpaccess file it will
not let that user log in. If I take out the guestgroup reference, it lets
the user log in as a normal user. I need the chroot() to happen so this
is no good to me!

I'm using wuftpd 2.4 (not beta II) - no need for the virtual stuff.
I'm running on a SCO UNIX v5 system, but I don't think this is relevant.
I searched the FAQ to no avail.

Thanks in advance
Pete

For security purposes I need to be able to set different
upload permissions for files and dirs. Basically, all
uploaded files need to be 644, no problem I have got
this to work both in the ftpaccess file and using the
ftpd -u option. Unfortunately, the uploaded dirs
also take on these permissions which means if a user
uploads his/her webpage with subdirs, the dirs created
also have permission 644, or drw-r--r-- . Then the
user can't cd into the new dirs to put the files there
because it isn't executable. An obviously I would like
to stay away from making all files/dirs 744 if possible.
Is there anything I missed?
TIA, Bill

This is RE: to my own message a few minutes ago.
I kept trying different combinations and this one
seems to work thought doesn't make 100% sense...

To make dirs 755 drwxr-xr-x reasonable for web
and files 644 -rw-r--r-- " " "

use ftpd with the -u022

I thought this meant everything made would be
755, but it seems wuftpd doesn't like to create files
executable, so it strips off the the last bit and
you get files 644 by default. - Which is nice because
user can up their pages with working subdirs and other
users can't edit their pages ;)

-Nice work again wuftpd!

Remember when you chroot users there are various bits and pieces which need to
be available to each user in their own chrooted file system - they can't see the real /usr/lib stuff. They all need their own usr/lib files and dev/tcp and dev/zero and bin/ls and maybe even etc/passwd and etc/group if you want ls to show usernames and groups instead of uid and gid numbers.

You don't say what errors you get when you try to login as a guestgroup user.
Anything in /var/adm/messages ?

What I did was the following:

- I added the following lines to the /etc/ftpaccess
log commands real,anonymous,guest
log transfers anonymous,real,guest inbound,outbound
and an virtual xxx.xxx.xxx.xxx logfile /yyy/xxx/log entry

Now there is nothing logged to the logfile specified with the virtual
line
and in the syslog only logons are logged.
Isn't there a way to log the commands, retrievals and errors (including
invalid logins) somewhere (or where are they logged) ?

Thanks for any help

I had the same problem here, and played around with access permissions

and that setup seems to work.

On Solaris, the devices seem only to work on disks which are mounted
suid, which I didn't know, some gurus may be able to explain...

I also copied the whole of /usr/lib/locale to ~ftp/lib/locale, but
I'm not sure whether this may be a reason for ls -l not to work.
Additionally, ~ftp/etc/group and ~ftp/etc/passwd must exist.

Cheers,

Oli

And on solaris, you can check th ORIGINAL man page for in.ftpd. wuftpd
install process overwrites it... :(

Check the original in.ftpd man page for a script that does most of the =
work
for you. i only changed some of the perms...

Unless I'm missing something obvious, you need to edit the
exports file on the toaster to export the appropriate file system(s)
with the root=<nodename> option,so that the server permits root on
the nfs client to be root on the nfs server (the toaster).

See the man pages for export for the syntax, if you're not sure.

Thanks for the reply Antony.

I've moved it on a stage!
I had already replicated the directory structure from the anon ftp user
for the new user (inc dev files and lib files).

NOW (I only tweaked some bits of the ftpaccess, ftpgroups files) I can
log in, the chroot works, but ls does not. The error I gett is the old
classic:
425 Cannot create data socket(0.0.0.0,20): Bad file number.

I tried running the ls file (as shown below) and it worked:

chroot /usr/suba /bin/ls

(where suba is the new user).
The SCO v5 UNIX is based on AT&T if that helps.

if you want ls to show usernames and groups instead of uid and gid
numbers.

I think you'll find that you need the dev/tcp file set to 666 in order
for passive (PASV) connections to work on Solaris 2. I had this problem
with my setup and found the solution in the FAQ :-

11. Normal ftp clients work, Netscape ftp's fail. So, passive mode
doesn't work.

Apparantly ftpd needs write permission on ~ftp/dev/tcp in order to
operate correctly in passive mode (Solaris). Set it to the same
mode as permissions shown by ls -lL /dev/tcp, being 666. Also read
the Solaris man page for ftpd for Solaris-specific information.
Changed from previous versions

Fix:

cd ~ftp/dev
chmod 666 tcp

Thanks to Simon Rakov ([email protected]) for
this one.

And thanks to Koos van den Hout for maintaining the FAQ, too...

Funnily enough, I was seeing the problem with webget - Netscape was working
OK (so perhaps it no longer uses passive connections ?), but clearly there
are products out there do use passive connections and won't work unless these
permissions are set. I simply made sure all my permissions in ~ftp/dev
matched the "real" ones...

Cheers, Bob

Oops. Sent the wrong patch. Here's the right one.

I made some modifications to your virtual ftpd support that may interest
you. I have cc'd this note to [email protected], in case it interests
the wu-ftpd developers as well.

Primarily, I allowed for hostnames as well as ip numbers in the ftpaccess
file. I also had the code use the first instance of each "virtual" command in
the ftpaccess file, rather than parsing the whole acl list and using the last
instance.

Also, I removed the code for what must have been the "old way" of handling
virtual domains, since it's not documented anyway.

I added a feature of my own (RESTRICTED_VIRTUAL_ADMIN) which allows remote
administration of a virtual ftp site by a single admin account, which is
restricted by chroot() to it's own account, and need not have a valid shell
(thus allowing for /bin/false shells to restrict the remote admin to ftp
only, and prevent the remote admin from accessessing anything but their own
virtual site via ftp).

Here's the patch:

I have about a dozen "chroot'ed" guestgroup accounts on my ftp
server, and have been copying the bin, dev and etc directories
around to each of them to handle the chroot'ed environment.

If I want to change the default message when connecting, or make
a change to one of these directories, I need to make changes in all
of them, thus having to do it 12 or more times.

Question: Does anyone out there have an elegant solution for
this problem? I considered hard links to the directory (all the
stuff is in the same file system), but Solaris 2.5 man pages indicate
that hard linked directories aren't allowed by the "ln" command.

Comments?

maybe you can give me some light.
i have read the faqs i found about wu-ftpd and tried to search this
mailing list but aparently nothing similar was comented in any
circumstances.

i have installed wu-ftpd without problems but now i am having
difficulties to configure it properly.

i have 3 kinds of users:

- anonymous: that should have access only to the pub directory.

- users: that should have access only to home/"his own directory"
and the pub directory.

- master: access to all directories but as non-priviliged user.

the "anonymous" and the "users" type cannot have access to the directories
below their directory three.

my question is.
can this be done with wu-ftpd?
if yes, please give me some clues how.

thanks in advance for any replies and help.
kindest regards.

Take a look at the guest howto below for the "users" type of access. Pay
close attention to it, and it should do what you want. You will also need
to set up the same 'ls' type structure for anonymous ftp.

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

On the same filesystem, make a master copy of the common elements such as
libraries, executables, etc. somewhere above all the chrooted accounts.
Then use hard links from each of the guest accounts back to the master
copy. You should install unlinked copies of the passwd and group files in
each ~/guest/etc directory with only the absolutely necessary information
for that account in each one.

I have just installed wu-ftp 2.4 under Solaris 2.5.1. We have guest user
set up. I can ftp to our ftp server and see that the user has restricted
access. The chroot is done, so the user can see only own home directory.
The user can `ls` and `chmod` to subdirectories. This looks good.

However, we want to set up a FTP URL from the Netscape browser to upload
files similar to above. The FTP URL works if we connect to the native
ftp. When we connect to wuftpd, the user cannot see any file listing,
even in his own home directory. It seems like the browser use the `LIST`
FTP request instead of the `NLST` request. What is the difference? Did
anyone try this successfully? Actually, if I specify `dir` from a
regular ftp client, I don't see any listing either.

Any help is appreciated!

Running wu-ftpd 2.4 on NeXTSTEP 3.3, using the "guest" mode FTP, that
chroot's the directory to the login directory, ls is not returning a full
directory listing. I am aware that library requirements probably exist, so
I'm wondering if anyone has done this under NeXT? The ldd/truss commands
do not seem to have a NeXT equivalent for determining which libraries ls
requires. Neither the wu-ftpd FAQ, or the guest-howto make any mention of
any special NeXT requirements. If anyone has done this under NeXT, I would
appreciate some pointers.

Thank You Much,
Matthew

One other reason I've seen is that the process
can't get a lock on the _PATH_PIDNAMES.
This will show in the logs with:
"sleeping: fcntl lock of pid file failed"
or something similar.
I usually kill the culprit, or if too many
shutdown ftp cleanly.

It's a nice little jig you have here ;-)
Have any trouble with it ?
Don't you think that the delay(120) is too short ?

I am *VERY* confused about the upload line in ftpaccess.

The perms only affects anonymous mkdirs and uploads, but the
nodirs effects both anon and private ftp mkdirs.

Isn't this a bit poorly designed?

I wish to prevent mkdirs for anon ftp because it creates
directories the owner can not erase. But private ftp should
be allowed to mkdirs.

Well I'll put in my two cents worth now...

In addition to checking syslog and the wu-ftpd xferlog for connections I
made a couple of changes to the ftpd.c source. These changes allow me to
type ps -ef (-aux or whatever on your system to show all processes) and
then pipe to grep and search for the string 'ftp'. Any current ftp
connections show up like this:

root 25139 607 0 12:38:14 ? 0:00 wuftpd eos.nasa.gov: cdavis: IDLE

If there are anon connections or file xfers underway these, along w/ file
names are shown. It is very convenient for us here as some transfer take
several hours and we don't always know it they are done or if they are
hung.

The changes I made are:

in ftpd.c (around line 1202):

#ifdef SETPROCTITLE
sprintf(proctitle, "wuftpd %s: anonymous/%.*s", remotehost,
sizeof(proctitle) - sizeof(remotehost) -
sizeof(": anonymous/"), passwd);
setproctitle("%s", proctitle);
#endif /* SETPROCTITLE */

(about line 1214):

#ifdef SETPROCTITLE
sprintf(proctitle, "wuftpd %s: %s", remotehost, pw->pw_name);
setproctitle(proctitle);
#endif /* SETPROCTITLE */

Note the "wuftp" text as the first part of the proc string. You could make
it read your favorite color or food if that suits you better.

In order for these change to show up you need to "#define SETPROCTITLE" in
the config.h file. I've heard some folks say that setproctitle function is
flaky but I've had no real problems with it. This is how ftpd worked on my
server before I installed wu-ftpd. It may not be for everybody but I like
it...

Also, I think (I can't remember if it was already there or not - I deleted
the original sources) I modified the following line in ftpd.c (line 1109)
so that 'last' would log the remote host name:

logwtmp(ttyline, pw->pw_name, remotehost);

This is helpful for me since I am mostly concerned w/ connections coming
from outside our domain and this is an easy way to view them.

nodirs is definitely broken in Beta-11.

I have a problem where 'dir' only shows uid/gid numbers instead of
names for anon users. (SunOS 5.5.1, wu-ftp 2.4.)

Done.

[email protected] said:

Done.

Well, I've got these across now, even though truss doesn't show them
being used, but still have the problem (no group/user names on dir
command for anon users).

There are 2 files in the truss report that don't show in the ~ftp
hierarchy:
# truss /bin/ls -l 2>&1 >/dev/null | grep '^open'
open("/usr/platform/SUNW,SPARCstation-10/lib/libc_psr.so.1",
O_RDONLY) Err#2 ENOENT
open("/etc/.name_service_door", O_RDONLY) = 3
Since the first isn't found during normal operations, I'm not worried
about it. However, I can't copy the 2nd:
# ls -l /etc/.name_service_door
-r--r--r-- 1 root root 0 Aug 1 12:52
/etc/.name_service_door
# cp -p /etc/.name_service_door .
cp: /etc/.name_service_door: read: Operation not applicable

Thoughts? (Again, Solaris 2.5.1, wu-ftpd 2.4)

I create many guest group and I just want to know if it was
possible to use some matcher in the root directory of a upload
information.

Example I have :

upload /arch6a/home/ftp/home/yacine /guest/for_root yes root root 0700 nodirs
upload /arch6a/home/ftp/home/yacine /guest/exchange no
upload /arch6a/home/ftp/home/yacine /guest/exchange/* yes root ftponly 0550 dirs
upload /arch6a/home/ftp/home/toto /guest/for_root yes root root 0700 nodirs
upload /arch6a/home/ftp/home/toto /guest/exchange no
upload /arch6a/home/ftp/home/titi /guest/exchange/* yes root ftponly 0550 dirs
../...

and some others with the same directory.
I try to creat a generic expression with no success :

upload /arch6a/home/ftp/home/* /guest/for_root yes root root 0700 nodirs
upload /arch6a/home/ftp/home/* /guest/exchange no
upload /arch6a/home/ftp/home/* /guest/exchange/* yes root ftponly 0550 dirs

Any idea will be great appreciate.

Regards Yacine.

Hi,
does anybody has a static compiled ls for Solaris 2.5?
Dynamic ls is much to slow...

One of the things you can use is the rdist command which comes with Solaris 2.5.
It is a distribution utility that will allow you to distribute a file to
specified destinations anytime the file changes.

I am having two separate problems (at least I think they are unrelated).

1) I have set up a guest account and it works, that is from a UNIX box. If I
use a UNIX ftp client I see everything that is in the directory and all commands
I have given access to in ftpaccess work. When I do a ftpwho it reports back
correctly. If I use SmartTerm's FTP client or Hummingbird's FTP client I
connect okay, passive mode, but see nothing in the home directory of the guest
account. Also, ftpwho and ftpcount report no one on the system, yet I do a ps
and see the ftpd running. What's up with this???

2) I have a common directory that everyone can read. I have a link in the
guest account directory to a file that is readable in the common directory. If
I login in and do an ls I see the link. If I try to get the link I am told the
file or directory does not exist. If I place the actual file in the account's
directory I have no problem accessing the file. What's up with this???

Yes, I've the same questions too
somebody kind enough to give some inputs ???

====
two cents
===
I update my free software for 3 reasons(in order)
1- security
2- bug fixes
3- new features

I've seen a lot of patches floating in this lists. But none
will fall under the 3 reasons above. Some are questionnable,
other are fixes particular to an OS, or just a question of view point on the
``right'' behaviour of ftpd. (BTW some are really nice 8)

If you have time to come up with a ``release''(Beta, Alpha, official,
non-official I don't care) if this version can check one+ of the above
mention reasons, Well I'll be the first to knock on your door (door number
21 that is ;-)

1-

IDLE does'nt mean necessarily dead(zombies)
it means "doing nothing"(shiftless)
it also apply to sys. admin ... i.e. lazy ;-)

Seriously if a client connect to you ftpd server and don't do nothing
the process is IDLE, it will eventually time out and die _if_
the client doesn't issue command to change the state.

If you kill the IDLE's then you may be killing some legitimate
connections.

I beleive you can change the timeout on the command line, here
the defaults values
-------------ftpd.c---------------------
int timeout = 900; /* timeout after 15 minutes of inactivity */
int maxtimeout = 7200; /* don't allow idle time to be set beyond 2
* hours */
-------------ftpd.c---------------------

2-

Now don't confuse IDLE processes with zombies(hang processes)
They were some previous posts on this matter(see the archive):
- can't get a lock
- connection from Web Browsers with the passive modes
-.....

I beleive that `Michael Brennen' had a small patch that can be
of help if you're overwhelmed with zombies(not IDLES ;-)(see archive)

Well if you insist
sure why not ? you have to do a little `massage' on the ouput

or just has good
ps -auxwww | grep ftp | grep IDLE | awk '{print $2}'|xargs kill -9

Very rude and not recommanded.
/bin/ps options may vary on the OS.

I don't think it will work .. at least not without some
serious work

1- won't work

the reason is zip/unzip(at least my old versions) can not do
zipping and unziping to stdout.

for exemple if I want to tar a directory and send this on stdout:

tar -cf - foo

can't do that with zip i.e.:

zip -r - foo # won't work

For the compression an tarring on the fly to work, the
programm must be able to send the result on stdout.

2- work arounds
a-
If you know zip well enough, you could change the src code
and send the result on stdout.

b-
_ I DIDN'T TRY THIS__
#include "disclaimer.h"
you've been warn.

It's possible to write a small wrapper to zip, it will take one argument
zip the directory and send the result to stdout. Wu-ftp will not even be
aware of it, something like:
: : :.zip:/bin/wrap_sip %s:T_REG|T_DIR:O_TAR:TAR

---wrap_zip(pseudo code)-----
get the directory name
zip the directory
send the result to stdout
---------------------------

3- dunno

ftp won't follow symbolic links to files outside the ftp directory tree
since it assumes everything outside the tree is off limits to ftp clients.

I have the same question and a proposal. I am one of the engineers at ONC
in Washington University. I help run wuarchive and this mailing list among
other things. If no one is currently taking care of wu-ftpd's source tree
I would like to volunteer. I don't mind scrounging up the patches floating
around and releasing a patched up version when appropriate.

BTW, I personally am new to wu-ftpd, and will be going through our mail
archives to bring myself up to speed. I replaced Brian O Connor, for those
who are interested.

Any comments/suggestions/flames will be cheerfully awaited.

naeem

Not zombies -- that is a particular Unix process state.

The patch *may* help with 'hung' processes -- normal processes that are
waiting for data that will never come.

YMMV.

Subject: Some ftpaccess lines work, some don't

Sorry if you got this before. I sent it Monday morning and never got it
back from the list.

We are using wu-ftp 2.4 on HP-UX 9.07 and trying to figure out how to
tighten security down a little more, but some of the parameters I've put
into ftpaccess do not seem to work. All lines below starting with "#"
are the complete, quoted ftpaccess (original of course doesn't start
with "#"). I have "ftpd -l -a" in the inetd.conf file. Everything not
commented on I believe works fine. My comments are unquoted and put at
appropriate places. Do I have something set up wrong? Is any more
information needed? The non-working functions I am mainly concerned
about are directory creation and file ownership and mode.

Thanks,

Boyd

limit line doesn't. Setting it to 1 it still shows 0 users with ftpwho
and ftpcount even when several people are logged in.

Directories can be created in incoming and are owned by ftp with mode 775.

# download /home/ftp * yes
# download /home/ftp/ * yes
# path-filter anonymous /etc/msgs/pathmsg ^[-A-Za-z0-9._]*$ ^[.-]

This string works, but the string in "man ftpaccess" does not (see line end):
path-filter anonymous /etc/pathmsg ^[-A-Za-z0-9._]*$ ^. ^-

Hi,

I want to create a directory under the FTP root so that anonymous users can
not access it, and to create an authenticated user to access only this
directory [can not access but the FTP root directory].

Does any body know how to create such a configuration?

Thanks in Advance

I think you need to get a newer version of zip: mine is version 2.1,
dated 04/27/1996, and supports output to STDOUT. Unzip is version 5.20
from 04/30/1996. I copied zip to ~ftp/bin and added the entry:

: : :.zip:/bin/zip -r - %s:T_REG|T_DIR:O_TAR:TAR

to the ftpconversions file, and was able to successfully GET a zipped
version of a directory.

No such animal. SUN neglected one needed .a file (can't remember which
one) for a successful static ls to be built.

get gnu fileutil 3.13 .. you can get it at
<ftp://prep.ai.mit.edu/pub/gnu/fileutils-3.13.tar.gz>

(perhaps does the patch also work for 3.14.. then it's
<ftp://prep.ai.mit.edu/pub/gnu/fileutils-3.14.tar.gz>)

gunzip fileutils-3.13.tar.gz
tar xf fileutils-3.13.tar

In the install instructions it tells you that you might experience the problem
you are having. In the support directory there is a file, ftp.h, that you need
to copy into /usr/include/arpa. Your compile errors will go away. I have
compiled this on Solaris 2.5.1 with no problem.

Subject: WU-FTPD compiling- Problem w/realpath
X-Mailer: MicroPlanet Gravity v1.01
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

When I am building FTPD (wu-ftpd-2.4.2-beta11) on UnixWare 2.1, I recieve
Undefined first referenced
symbol in file
realpath_on_steroids extensions.o

Now if I edit config.h and remove the #define realpath, I then get
UX:acomp: ERROR: "extensions.c", line 99: identifier redeclared: realpath
*** Error code 1 (bu21)
UX:make: ERROR: fatal error.

Am I missing a lib for realpath_on_steroids or am I missing something
here?

TIA

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

Can you be so kind to give a __FULL__ path of that library

To compile ls statically I had to provide
stubs (dlclose.o, etc..) on the command line

(I'm sure you've all heard of a similar problem, but maybe not
one quite like this...)

# /bin/ftp
ftp> o localhost
Connected to localhost.
220 onyx FTP server (Version wu-2.4.2-academ[BETA-11](1) Fri Dec 13 16:41:51 PST 1996) ready.
Name (localhost:): yoshi
421 Service not available, remote server has closed connection
Login failed.
No control connection for command: No such file or directory
ftp>

Immediatly at this point, I receive the following error in syslog:

Dec 13 17:13:04 onyx ftpd[4042]: exiting on signal 11

/etc/ftpaccess is being used (#define USE_ETC), as shown below:

# strings -a /usr/sbin/wu.ftpd | grep ftpaccess
/etc/ftpaccess
Too many args (>%d) in ftpaccess: %s %s %s %s %s ...

And these are the command-line arguments i'm passing:

# grep ftp /etc/inetd.conf
ftp stream tcp nowait root /usr/sbin/tcpd /usr/sbin/wu.ftpd -a -l

What i'm concerned about is the "No control connection for command"
line sent to me via wu-ftpd. As you can see, I am using the -a, -d,
and -l options. /etc/ftpaccess exists, and is readable.

If I remove the '-a' option, the aforementioned error goes away,
and lets my users login: the drawback is that I cannot make use
of the "/home/username/./" feature for chroot() in limiting users
to which directory is considered root (/). The user 'yoshi' is
a normal user, with no "wu-ftp" features in his path or etc..

If someone could direct me on what exactly is causing this problem,
i'd be grateful, as our ISP requires the "/./" feature.

Ah, and before I forget: Linux v2.0.27, libc 5.3.12, gcc 2.7.2.

Thanks.

The major pains in the ... neck, of wu-ftpd are:
- the chroot()
- the external execution of ``bin/ls''
this two are probably 80%++ of this mailing list traffic.

Seing your static-ls patch(previous post) made me wonder
I hard will it be to have a BUILT_IN ``ls''
in wu-ftpd.

Having built_in ``ls'' may:
- improve performance
- will alleviate the needs
for those (*#&@^*&$) <-- put your best(worst) blasphemy here
~ftp/dev/*
~ftp/lib/*

Especially on Solaris well to have ``bin/ls'' kicking,
you must populate ~ftp/lib/* ... sigh

Unfortunatly, I will not have time to explore this (I promised
my girlfriend that I would not even look at a computer this chrismas).

But if someone have try this or have
Comments/suggestions/etc.. let me know.

Yes, I had a very similar problem, just after entering a user name I
would get the same error that you are reporting. The advice that I got,
which has made everything work perfectly, is as follows. Signal 11 is a
segmentation violation which could indicate that an address is not being
properly de-referrenced...i.e., a bug in the program. The solution I
received was simple, but worked perfectly. All I did was re-compile the
ftpd using the latest gcc compiler. I was using gcc 2.4.5, which is
ancient and caused the problems. The newest is gcc 2.7.2.1

well,

it's my xxxxxxxx same questions for the same problem, in mailist
or newsgroup...
i receive for the SAME question: "IT'S NOT POSSIBLE", "IT'S POSSIBLE"
"NO", "YES", and so...

The question (simple no?) is:
"is it possible to use Symbolic links and not realpath for
real users with wu-ftpd ?"

now for the xxxx time (:_o ):

OS: Linux 1.2.13
FTPD: wu-ftpd-2.4.2b11

#df
/dev/hda2 /
/dev/hda1 /files
/dev/hdb1 /disk2

#cat /etc/passwd
[../..]
ftp:*:404:100: :/disk2:/etc/ftponly
guest:*:405:100: :/disk2:/etc/ftponly
userX:xxxx:406:100: :/disk2/users/userX:/bin/bash
[../..]

#cat /etc/group
[../..]
wheel::10:root
ftp::16:ftp
users::100:root
[../..]

in /disk2 i have:
/disk2/bin/ls (static)
/disk2/etc (with *.msg, no "passwd", no "group")

The /etc/ftpaccess is the origin file

in /disk2/users/userX i have:
#ls -l /disk2/users/userX
[../..]
lrwxrwxrwx root root dir1 -> /disk2/dir1
lrwxrwxrwx root root docs -> /files/docs
lrwxrwxrwx root root job -> /usr/local/job
[../..]

The "userX" can go in all of these directory (great !!)
BUT ! when he would like to come back ("cd ..") in the
$HOME directory the result is:
/disk2 for dir1/
/files for docs/
/usr/local for job/

stupid no ?
with "telnet" the result is ok.

so:
- wu-ftpd CAN'T use Symbolic ?
[]YES []NO
[]other....
- Must i change something ?
[] go to windows95
[] job
- How can i do to make it ok ?
[] use another ftpd
[] do what ftp want not what you want
[] kill users
- With guest account is it big crazy ?
- Do you want pizza ?

Please, if you have a think like this show me
how you make it...

Thank's !!!!

Thierry,

Indeed I can't understand why wuftpd never used a built-in 'ls'. This
should not be impossible as anonftpd has one. But external libraries & co
will still be needed if you want to use tar/gtar/compress/gzip ( these might
be also implemented as built-in ) .

The thing is that libdl.a is the .a file that sun neglected to ship with
Solaris 2.5 ..

That is why you needed libdl.a .. to get those functions .. but as a
static-ls it really don't need those functions .. dlopen(), dlclose() ..
is handling the dunamically linked library ..

And for getting uid to user conversion you (according to solaris manuals)
really need the dl-functions .. or you can do as Brett Porter
<[email protected]> and I did .. patch the gnu ls ..
to fix the uid to user mapping .. and include the stubs .. It workes great
.
(I have sent it to the list ones .. I wont do it twice .. it should be in
the archive somewhere ..)

hmm .. you are perhaps correct .. but I think I have seen more RQST for
FAQ (or similar) ..

The patch is not an ls itself .. it is just a patch to include something
that already is in the gnufileutils .. the uid to user mapping ..

It wouldn't be hard to include that in wu-ftpd though .. a simple stat
will return the uid and .. and naturally is ls -lR not possible (if it
isn't coded) ..

and also it could be configured so that it uses the built in long_ls()
only if it is in chrooted environment ..

hmm .. those libs would perhaps still be needed if you would want to run
extern programs .. (SITE_EXEC) ..

Or you could patch gnufileutils .. and do a make ls ..

Hmm .. my gf is trying to force me to do the same.. :-( .. and I guess she

But as I have work to do with my student union .. I have time to patch

Hmm .. if all unix hackers (not cracker hacker, I ment programmer hacker)..
come together it wouldn't be that hard to fix that ..
you could do it as easy as a <hacked this function>.c with a header file
<hacked this function>.h that is included where the wu-ftpd-staff want it
to be called ..
ls -l could be called long_ls .. (long_ls.c,long_ls.h)
gtar -> gtar() .. (gtar.c,gtar.h) ..

but I think it is easier to use external commands ..

A new release candidate for version 2.4.2, which will be beta 12 will be
released on January 10, 1997. This version will bug fixes only. No new
features will be added. After this release, version 2.5 alpha will be
released (no date is yet set) which will have some new features and
completely new ways of doing installation that is much more friendly to
the novice system administrator. As that will be alpha code, it will
only be released on a limited basis.

During 1997, it is my hope to get 2.4.2 to release and move all development
work to 2.5.

Thanks for your attention.

I receive the exact same premature exit 'signal 11'; I have
upgraded to gcc v2.7.2.1, and libc 5.4.13, as shown:

# ls -l /lib/libc.so.5*
lrwxrwxrwx 1 root root 14 Dec 14 23:44 /lib/libc.so.5 -> libc.so

# gcc -v
Reading specs from /usr/lib/gcc-lib/i486-linux/2.7.2.1/specs
gcc version 2.7.2.1

I also tried removing the -O2 level optimization, dropping it down
to just -O.

Any other ideas? I'm desperate to get this working, as a few of
our customers need this type of feature.

Greetings,
I'm having a little problem getting the dir command to work, when
someone ftps in to "anonymous". The "ls" command works fine, and there is
a link to "dir" in ~ftp/bin. If the user accesses their own account, then
both "ls" and "dir" work fine. I'm using wu-2.4(1), running on an RS6000
under AIX 4.1.4. I'm guessing it's something simple, but I haven't been
able to spot it yet. Any help will be greatly appreciated.

Patch to wu-ftpd-2.4.2-beta-11.

=46rom the README file:

This patches ftpd, ftpcount, and ftpshut to accept an optional argument to=
the -a command line option so that the ftpaccess file can be placed in an=
alternate location. The primary benefit to this is that the tcpwrappers=
package can be used to start ftpd with different configuration files based=
on a wide variety of characteristics associated with the network packets=
requesting FTP service. This provides the mythical precise and total=
control of virtual FTP servers usually only associated with luxury sports=
cars. =20

The convienent thing about this patch is that, with tcpwrappers, every=
ftpaccess directive effectively has a "class" argument. I like using=
tcpwrappers to define classes because that's what it's designed to do, and=
it can do it in many ways, including destination IP.

It would be nice if someone would write a "ftproot" directive for the=
configuration file. This would specify the directory to chroot to for=
anonymous ftp users. The advantage is that then the existing "virtual"=
directives would never need to be used. This would keep IP numbers from=
appearing in yet another configuration file, the ftpaccess file.

Rpms have been uploaded to
ftp://ftp.redhat.com/pub/incoming/wu-ftpd-2.4.2b11.9-i386.rpm
ftp://ftp.redhat.com/pub/incoming/wu-ftpd-2.4.2b11.9-i386.rpm-try2 (Which is=
the same as *.rpm. Don't ask.)
ftp://ftp.redhat.com/pub/incoming/wu-ftpd-2.4.2b11.9-src.rpm

The patch is available at:
http://www.meme.com/soft
ftp://ftp.meme.com/software/wu-ftpd-2.4.2

I tried to upload the patch to ftp://wuarchive.wustl.edu, but there dosen't=
seem to be an incoming directory. I'd appreciate knowing how to get the=
patch to them.

I would appreciate it if this patch was added to the wu-ftpd FAQ.

I would appreciate it even more if Washington University would incorporate=
this patch into their distribution so that I don't have to maintain it.

I have the virtual ftpd deamon and when I try to access the virtual host
it comes up with a 550 error that it can't set guest modes. I changed the
directory to my main anon ftp and it still does the same thing. I would
like to know what might be wrong and why I can't get anon ftp to work on
this ip. It does the banner and all.
Thanks Adam

You'll need stuff in ~/ftp/dev and ~/ftp/lib for other things, even with a
builtin (or static) ls.

While a builtin ls shouldn't be difficult to add, and might be a useful
efficiency hack, under Solaris you'd still need stuff in ~ftp/lib if you
want a builtin ls to support all the different lookup options for user
names and groups.

Yes, users that are not chroot()ed can follow symbolic links.

WUFTPD is correct. You have followed the link and have a new
working directory.

The reason Telnet works for you is because your user has bash for
their shell. One of the nicer features of bash is the ability to
cd.. back through a symbolic link. If you try a different shell (sh
for example) you would see that you can no longer cd.. back through a
symbolic link.

Keith.

You need to get the guest howto and go over it carefully to set up 'ls'
and friends.

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

I have the following line in my etc/ftpaccess

message /export/home/tempt/.message login

My real users are able to see this login message using a command prompt
and by using Netscape, my virtual users are unable to. Also, that same
should actually read as follows:

virtual 123.123.123.123 message /export/home/tempt/.message login

This is so only the virtual users accessing their account see their
specific login message. Anyone with any information please, I could use
your help. Thanks.

Here is a little patch to provide a built-in 'ls' to wuftpd 2.4.2-b11
.. So no more /etc and /bin directory is needed for anonymous ftp and
this may also fix some security holes. Also a new compilation flag was
added in order to avoid launching any external program.

Best regards, Frank.

Ran into the same problem myself recently. No dont take an old one.
Just look at the makefile for the vers target. It uses a shell program to
build it dynamically. Not sure why this doesnt happen automatically, but
anyway after I ran shell program that created a current vers.c the rest of
the build went fine.

Excellent patch. One small "problem":

Your ls doesn't support any command-line arguments like standard
BSD & GNU ls, used from shells. The result is that no data is sent,
and FTP returns a prompt immediatly. This even happens on your
own site. Commands such as "ls -l" or "ls -FRal" do not work.

Besides that, looks good!

We're having problems with the good ol' MKDIR bug (i.e. 'nodirs' in
ftpaccess blocks out normal users in addition to anonymous). Didn't
someone post a patch for this a few days ago? If so, I no longer have it
(and the mailing-list archive seems to be kind of messed up...the html is
chopped off at Dec. 9th) -- would whoever posted the patch be kind enough
to re-post it?

Thanks in advance.

I did not look at the 'ls' patch, but if that is all it does, there is
already an ls built into wu-ftpd that will not take command line
arguments; the patch is entirely superfluous.

The external ls is forked when command arguments are given, which some ftp
clients seem to do by default. If you want to obviate the need for an
external ls, you are going to have to write a complete ls that will patch
into wu-ftpd.

IMO this should not be in the source tree; it should be available by patch
for those who want it. I would not want to burden an already overbig
server with yet more baggage.

I'm sure someone will correct me if I'm wrong, but isn't it possible to
put copies, or hard links to your /lib/libc*.so.* into your ~ftp/lib?

Of course.

But when you have 400 to 800 users who want this feature, so
customers can pull their newest file distributions, you start
to notice most of your disk consists of libraries for anonymous
FTPs. A static 'ls' binary is much more suiting for what we
need :-)

A- Static-ls

(Solaris FAQ:You'll find pointers)
http://www.fwi.uva.nl/pub/solaris/solaris2.html

I don't want to delve into this, but providing static bins may
help in certain cases, however it's not|rarely recommended.

For solaris because sockets implementation is build over
STREAMS, you still need to provide

~ftpd/dev/tcp(666)
and maybe some other stuff under ~ftp/etc and ~ftp/lib

But all that said, I agree with you
it's still simpler and less error prone with static bins.

B- Share OS(platforms)

Maybe my previous post was misleading.
In fact I use dynamic bins for wu-ftpd, under solaris with no problem.

My real problem was that ~ftp is share across OS (SunOS and Solaris)
Although it's allright for ``real'' users
things will break for ``anonymous''.

There's no clean way to deal with this:
1- playing with the mount entries, passwd file(ftp home) etc..
is very messy.
2- providing built_in ls seems a good idea but to quote
`Michael Brennen ' :
" I would not want to burden an already overbig
server with yet more baggage."

My network is coming more heterogenous, it's allright
for the others services, it's a problem with wu-ftpd because of
the chroot().
There are some interesting patches posted, I look a them after
the X-mas break.

C- workaround
For now I'm using the ``guestserver'' to redirect ``anonymous''
to one central server were ~ftp is setup right.

You just need one copy of the libs per filesystem. The libs for all of the
users who live on the same filesystem can be hardlinked together.

Hi. I'm new to the list (just sub'd this morning), but I think I get the
gist of this thread. I have a setup here where using an external ls is not
feasible. I solved the problem very simply, by using the ls code from GNU
fileutils.

It's two source changes- one to ls.c changing main() to ls_main(), and one
to ftpd_popen(), to call ls_main() instead of exec(), if the program to be
executed is ls. I build the fileutils support libraries as usual, then link
with them and with the two ls-specific objects. It's fat but it's
compatible.

This seems to be the case.

My statement above is solely in response to someone recommending
I copy all libs used by Solaris ls (via ldd) to ~ftp/lib.

If I have 400-800 clients who want to make use of this feature
(using 'guestgroup' in /etc/ftpaccess), copying libraries begins
to take up a significant amount of disk.

It was then recommended by Bill Sebok that I could use hard-links
which works, but I personally took the static ls approach -- and
so far, everything has been grand.

For 400-800 accounts? I think not.

And this was my point in the very beginning, or atleast how I

Implementing an option under wu-ftpd to support the ability
of compiling in GNU ls (from fileutils) is a good idea -- GNU
re-created the wheel, there's no need for us to write the
sourcecode when minor adjustments can be made to wu-ftpd to
actually support linking in GNU fileutils's ls.

Right, and this all boils down to the fact that the best solution
right now is to compile a static version of ls -- which I have
done, and all is well. Hurray. :-)

(I honestly didn't expect this subject to become such a large
discussed thread, but it's apparent this is a concern to all
users of wu-ftpd, so we might as well approach it, if it hasn't
be approached prior to now).

Process info set by SETPROCTITLE code will not be visible in Solaris 2.X with
the standard "ps" command /usr/bin/ps. However, you will be able to see this
info if you use /usr/ucb/ps. Whether this is a bug or a feature is a matter
of opinion. It does prevent hackers from hiding what they are up to.

Why not? If you use hard links you don't take up any more disk space (just
one copy per file system is required.) So, what's wrong with this method?

No this will not work, the matching(globing) is only done on
the second argument(dir-glob) of the `uplaod' directive, not
on the root-dir.

NOTE:
And it me be a suprise for you, but for example for this
line to work properly

> upload /arch6a/home/ftp/home/* /guest/exchange no
^^^^^^^^^^^^^^^^^^^^^^^^
the first argument(root-dir) __must__ match exactly the HOME field in
the passwd file, if not so, then people will be able to upload
even if you specified "no".

IMHO
Don't be to smart with the matching expression. The
regex in wu-ftpd is ok... but it's not perl. Better
a couple of lines more, but at least you're sure
of the behaviour

I don't know if this is a good idea or not, but you _may_ be able to do what=
you want using the command line patch I recently posted to allow multiple=
configuration files. (http://www.meme.com/soft) You would use it with=
tcpwrappers and the ident protocol. Tcpwrappers together with ident would=
determine the group and run ftpd with a different configuration file with=
different upload directives for each group. See the tcpwrappers=
documentation to see how well you might be able to make this work. You can=
find a tcpwrappers distribution point linked at the URL above.

Note that this is not particularly secure because ident is not particularly =
secure.

Changes from Jedipatch#1 :
~~~~~~~~~~~~~~~~~~~~~~~~~~

- Idle servers bug removal.
Patch suggered by Michael Brennen <[email protected]>

- Ehanced virtual FTP support.
Patch send by Scott Barker <[email protected]>

------------------------------ Scott said : ----------------------------------

Primarily, I allowed for hostnames as well as ip numbers in the ftpaccess
file. I also had the code use the first instance of each "virtual" command in
the ftpaccess file, rather than parsing the whole acl list and using the last
instance.

Also, I removed the code for what must have been the "old way" of handling
virtual domains, since it's not documented anyway.

I added a feature of my own (RESTRICTED_VIRTUAL_ADMIN) which allows remote
administration of a virtual ftp site by a single admin account, which is
restricted by chroot() to it's own account, and need not have a valid shell
(thus allowing for /bin/false shells to restrict the remote admin to ftp
only, and prevent the remote admin from accessessing anything but their own
virtual site via ftp).

------------------------------------------------------------------------------

- The built-in 'ls' didn't deal with command-line options. This is now
( lazily ) fixed.

- Non-anonymous clients that use the built-in ls due to the NO_EXEC option
will now read the real group and owner.

- Two distinct Linux configurations are now provided.
./build lnx -> build wuftp for Linux without shadow passwords
./build lns -> for Linux with shadow passwords

The source was also patched to compile fine with Linux 2.1.x and libc
5.x.y .

This patch and the whole patched source code are also available from
ftp://ftp.edit.fr/pub/j/patches .

Ps: Adding a built-in 'ls' is not only getting the source code of GNU ls
and renaming 'main' to 'ls_main'. You will also have to parse differently
each argument, scan and match regular expressions and output the result to
a socket with the right protocol. This patch implements all of this and
the core of the 'ls' source code ARE taken from the GNU ls.

Best regards, Frank.

i looked at my ftpcount.c src file and found it is different from yours.
*** 226,233 ****
stat = kill(buf[which], SIGCONT);
if (((stat == -1) && (errno == EPERM)) || !stat) {
if (strcmp(progname,"ftpcount")) {
#if defined(SVR4) || defined (M_UNIX)
sprintf(line,"/bin/ps -f -p %d",buf[which]);
#else
sprintf(line,"/bin/ps %d",buf[which]);
#endif

i applied your sugested change but i still only get :
Service class mel_ftp:
ftp 7876 143 1 08:43:51 ? 0:00 in.ftpd -adolLi
- 1 users ( 50 maximum)

am i missing a lib file perhaps??????

I can't find documentation for it, but it seems to be argument
specific....

<pecos>:add % ps -agux | grep sendmail
add 1005 0.4 0.9 756 536 pts/4 S 09:38:15 0:00 grep sendmail
root 220 0.0 1.5 2164 912 ? S Oct 22 0:04 /usr/lib/sendmail

aguxww works, I know I've managed it before with a smaller set... I
don't remember what it was. I think agxww will also work.

for their input all three pointed me to problems and solutions with "ps"
this pointed me in the right direction.

i also had to redifine

to
#define SPT_TYPE SPT_PSSTRINGS

that with the suggested change to ftpcount.c have solved my problem.

Subject: Question about /dev/null
Content-transfer-encoding: 7BIT
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

Hi.

Sometimes, to test network performance, it is useful to be able to
upload a file (like /kernel/genunix) to a ~ftp/dev/null (assuming the
nod has been made)...

However, most configs don't allow users to overwrite a file in ~ftp/dev.

Is there a simple fix to the ftpaccess file that allows anonymous users
to put images into this device file?

(please reply directly)

Thanks,

-Philip

Subject: ftpd CPU usage increases when idle
MIME-Version: 1.0
Content-Type: TEXT/PLAIN; charset=US-ASCII
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

We've recently noticed a problem with significant system load and have
tracked it down to periods when there are several incoming ftp
connections. Watching the behavior of ftpd, we've discovered that the
process takes up the *most* CPU time when it's *idle*. One would expect
an program waiting on input for further instructions to take up zero CPU
time until an interrupt signaling incoming data or a timeout wakes it up.
Is wu-ftpd sitting in a wait-loop here?

If anyone can help me with this (preferably patches or configuration
instructions that fix it) I'd really appreciate it.

Excuse me, but I should clarify that... *sometimes* its CPU usage jumps
way up. Most of the time it's insignificant, but when the system load
spikes, we can be sure to find three or four high-CPU-but-idle ftpd's in
the top 20 processes. When they go non-idle, their CPU usage drops back
down.

(maybe the answer to the subscribe message should point to a faq)

here's my problem:

i'm running wu-ftpd-2.4 on solaris2.5
i'd like to use the guestgroup function, and it seems to work
successfully.

this is the setup

/usr/local/etc/ftpaccess:guestgroup ftpgroup1
/etc/passwd:ftpguy1:x:2002:401:test ftp user \
2:/ftp/./dir1:/usr/local/etc/ftponly
/etc/group:ftpgroup1::401:

i log in like that and most of the time when an ls is issued, we get
this...

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

if a regular user (me) ftps in, i have no trouble.

anyone else experience this/know what's up/can tell me where there's a
FAQ?

thanks,

-David

This is most commonly a device problem - check yours are made as per
requirements.
Another reason can be the execute permissions on the bin directory (this
was my problem after doing sweeping security group changes).

Use the tcp_wrappers package and issue an TWIST command on the FTP
port.
This is described in detail in the tcpd manuals.

Good luck

Interesting idea, you don't want to install any new program on the
maschine?

I just tried this:

/etc/inetd.conf:
# ftp stream tcp nowait root /usr/local/lib/ftpd/bin/ftpd ftpd -a
ftp stream tcp nowait root /etc/noftpd noftpd

/etc/noftpd:
#!/bin/sh
cat <<EOX
220-This FTP Server is down, use ftp.wu-wien.ac.at
220-bye bye...
EOX
# /usr/afsws/local/bin/nvt ftp 21
telnet ftp 21

This seems to do the trick. If you have a glass telnet or a TCP relay
like nvt at hand, use this instead of the telnet.

Folks,
Is there a way to disable the use of PASV mode in WU 2.4 so that who
ever is requesting it will use standard mode. Also if you can't
disable it, can you limit the ports that are returned in the
handshake so that from a security standpoint/firewall you have
smaller window of open ports. This is from the point of view of the
ftp server being behind a firewall and the clients in the general
internet population.

Thanks
Doug

Can anyone supply or point me to info on wrapping wuftp so that as a
client is about to download or finished downloading some other
programs can be run and results of these other programs can be
displayed back to the user during the users session. One way would be
just modifiy the code at the appropriate place to exec the desired
program, but I was looking for something more standard.

Thanks in advance

>Where can i read about configuring virtual ftp servers using wu-ftpd? Thanks

For more control over virtual ftp servers use tcpwrappers to spawn ftpd
with different configuration files. See the the patch at
http://www.meme.com/soft and read the tcpwrappers documentation.

If you do this, you will find that common ftp clients -- like netscape --
cannot connect to your server. It's an ulgy fact of life with an RFC to
document it, I think something in the 1500's. This RFC proposes that all
clients use PASV mode, in violation of the RFC which defines the ftp
protocol. I'm pretty much resigned to it.

The solution is probably to use gopher instead of ftp -- although I seem to
recall the RFC proposes gopher do this too. I'm blurry about this because
I thought that gopher used only one connection, which is why I say that
gopher is the solution.

Hello,

I am new to the list so I am sure this has been asked and is probably
somewhere in a FAQ, I want to install wu-ftp on a Solaris 2.5.1 system with
the virtural servers option. Is there a FAQ on this, I see in the read me
that it has been tested on 2.4, but I'm running 2.5.1. If there is a easy
FAQ somewhere point me in that direction.

Yours,

Subject: Virtual FTP Servers

[Modifications to provide for discrete xferlogs for each server provided by
Marc G. Fournier <[email protected]> -- sob.]

I'm attaching a patch for wu-ftpd 2.4 to allow virtual ftp servers to be
setup. Basically so a user ftping to ftp1.domain.com gets one ftp banner
and one ftp directory and a user ftping to ftp2.domain.com gets another
banner and directory even though they are on the same machine and port.

I was the person who originally asked how to do it, and got enough answers
to write a patch that would allow it. You have to be able to setup alias
IP addresses in order for this to work. I know linux and bsdi support this.
I do not warrant this code at all. Use it AT YOUR OWN RISK. If it causes
your computer to blow up, TOUGH!

Please send me comments, I'm interested in improving it, and hearing
how it works for people.

Here's the steps.

Compile the software with -DVIRTUAL added to the CFLAGS in the Makefile

Add lines similar to the following for each virtual server to ftpaccess:

# Virtual Server at 10.10.10.10
virtual 10.10.10.10 root /var/ftp/virtual/ftp-serv
virtual 10.10.10.10 banner /var/ftp/virtual/ftp-serv/banner.msg
virtual 10.10.10.10 logfile /var/log/ftp/virtual/ftp-serv/xferlog

The first arg is the ip address of the virtual server.
The second arg is either "root", "banner" or "logfile" (without the quotes)
for that virtual server.
The third arg is the file system location for the item specified in the
second arg.

Note: all the other message files, etc, and permissions and other settings
in the ftpaccess file apply to all virtual servers.

That is the full URL. I was just now able to download the WU ftpd source
by using exactly the URL below. I guess I don't understand what is going
on if you can't load it. You cannot see the contents of the private
directory, so you won't be able to point and click it, but it is there.

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

The above *is* not an URL, it's relative to the wu-ftpd sourcedir. Forget
WWW and URL's for one <beeping> second, think Unix homedirs.

Don't you hate it when the cluefone is ringing and nobody answers ?

General note : Yes, I have a backlog in updates for the faq. This
backlog will grow since I am the proud owner of an appartment since 2

Now you've done gone and reminded me. The FAQ should have pointers to the
ftp rfcs, both the protocol and the "revision".

When I type "./build lnx" i get . .
Ok.. I get some ERROR 1 on FTPSHUT and the one previous.

When i do "./build install" i get. . .
make: *** No rule to make target `bin/ftpd', needed by `install'. Stop.

I have attempted to traceout the 'build' script and see what actally
happens.. from what I can figure out is it winds up running:
install program and yet still bombs on me.

2nd?
I run Beta9 Now --- How come my Windows GUI clients (cuteftp, WSFTP)
doesn't list a directory .. but i can change to dirs that i know exist

I'd start by getting the latest source rpm from redhat and try building it/checking out the patches.

Okay, here's a wierd one for ya ... normally you can resume downloads with
cuteftp and such ... but now with this new wu_FTP (beta 10) you can't. It
doesn't even prompt to resume. Any ideas? there's a #define OVERWRITE in
the config.lnx file but I don't know if that's it........... humph. :)

Let me guess...:
The problem was:

glob.c: in function 'matchdir':
glob.c: 240: dereferencing pointer to incomplete type
make: *** [glob.c] error 1

If so, then add "-DDIRENT_ILLEGAL_ACCESS" to the CFLAGS line in the
Makefile.lnx

See above. It can't install because the binaries were not built.

Actually, this is just a shot in the dark but it would have helped if you
could have provided the output given by the error.

It's the famous static-ls problem which accounts for 50% of this list's
traffic. Here is the location of the FAQ, to help you solve this problem:

WU-FTPD FAQ: http://www.hvu.nl/~koos/wu-ftpd-faq.html

Basically, this is just a matter of putting the right libs under ~ftp/lib
so that your ~ftp/bin/ls can work.

I'd recommend, as did Karl, getting the patches for wu-ftpd for
RedHat. If the problem you have has something to do with dd_fd
in 'glob.c' and some other things, EMail me and i'll send you
the modified 'glob.c' I have (which removes this problem).

I just installed wu-ftpd-2.4.2b11-8.i386.rpm on my redhat system.
Everything seems to work fine except the -u flag. Here is my inetd.conf
entry:
ftp stream tcp nowait root /usr/sbin/tcpd in.ftpd -l -u033

When I put files as a normal user, they are mode 644 which is good.
However, when a user makes directories, they are mode drwxr-Sr--. That's
no good. I've tried replacing my ftpaccess file to the default, no
dice.. I have a slackware system on which I compiled the same version and
it works OK.. Any ideas?

It's because the group setuid bit is set on the directory in which the user
is creating a sub-directory. It's supposed to work this way. See the
redhat installation and users guide for information on the
unique-group-per-user administration stratigy. If you _really_ don't want
it to work this way you have to set bits in the first byte of the umask (it
has 4 bytes), read the chmod man pages to see which are which.

Dear wu-ftpd user,

I've built wu-ftpd-2.4 under Solaris 2.5.1 (libc patches installed)
using gcc gcc-2.7.2.1.

There is a user named "username" defined in the system passwd file but
not in the ~ftp/etc/passwd file. His home directory is
"/home/username".

When an anonymous ftp client logs into the machine and types
"cd ~username" wu-ftpd responds "/home/username" no such file or
directory. The chroot is working, the client itself doesn't have
access to the system passwd file.

The problem is that it lets anon users probe to see what accounts are
defined.

I suspect this is a cacheing problem with nscd. Truss shows calls to
"door_info" and "door_call".

Has anyone experienced a similar problem? Any help would be
appreciated.

When a user logs onto my system I want the chroot command to execute so

In other words I want t oknow if there is a way to make a user-type clone

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

Zach,

Try this:

ftp stream tcp nowait root /usr/sbin/tcpd in.ftpd -a -l -u033

Without the -a option, the daemon does *not* read the /etc/ftpaccess file.

You can also use something like:
guestserver ftp.wu-wien.ac.at
in the ftpaccess file though this will not launch an ftp session.
It will give a similar message, namely saying the user should connect to
the guestservername.

The expand of "~" is done by wu-ftpd
On my SunOS4 boxes the behaviour is right
if you loggin anonymous and try to do
cd ~username
and username is not defined in ~ftp/etc/passwd
you'll get the "550 ..Unknow user.." error
Eventhough username is a real user.

Now i didn't try this on Solaris.
but If you find it to be a nuisance
you can disable the behaviour by
recompiling.

in ftpcmd.y, look for pathname:
and get rid of the strncmp(..,"~")
this will stop the globbing for ~

Thanks, I may try this. Someone on the list suggested I try putting
the following line in my /etc/nscd.conf file:

enable-cache passwd no

I did this and it solved my problem. Which is scary. It means that
on Solaris, the system passwd file is cached even in a chrooted
environment. This could possibly lead to other vulnerablities.

I tested this on a SunOS4.1.4 machine and doing this causes wu-ftpd
to dump core.

I had posted that the following fixes my problem. It stops revealing
my real system passwd users. But it also causes wu-ftpd to dump core.

enable-cache passwd no

Doing a cd ~realuser caused a core dump on both SunOS and Solaris machines
using the version of wu-ftpd at the wustl ftp archive.

When I built the version at acedem.com (wu-ftpd-2.4.2-beta-11) for
Solaris the core dumps stopped. Although the connection is broken.

I used the attached manual that was sent out a couple days ago to try and
setup a chroot situation for a user. Well, when my user logs into the
ftp site it says," User myusername logged in. Access restrictions apply."
However, it doesn't log into myusername's home dir. IT does a chroot to
the e anon ftp dir. I have a passwd entry of
myusername:*:193:10::/my/users/d/dir/./:/etc/ftponly
located in my /etc/passwd /my/users/dir/etc and /my/anon/ftpdir/etc/
I have group files with the text client::400:scienc in those same three
places. What's not working? Ideas?

Subject: Shadowed passwords on AIX
Mime-Version: 1.0
Content-Type: TEXT/PLAIN; charset=US-ASCII
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

Hello,

I'm trying to build the wu-ftp-deamon on an IBM rs6000 running AIX.
I compiled the source-code, installed all the nesaccary files and testet
the new FTP-deamon, and there was the Problem. I couldn't log in as a
REAL-User. I searched the Internet and found a FAQ where I found my
Problem. So I created a file ETC/SHELLS...No Problems.
BUT HOW CAN I IMPLEMENT SHADOWED PASSWORDS ?
There is a solution for Linux User. But I have no file shadow.h and I
don't know how to get it...
Has anybody build WU-FTPD on an AIX with shadowed passwords ? How ?
Please help me...

So long and thanx for all the fish,
--

First, I've read and applied the guest-howto information, I've double and
triple checked everything I could find. I know this is asked repeatedly,
and I even went and looked in my archives but didn't find anything.

This is using 2.4.2 beta 11 on linux 2.0.24, libc 5.3.12 and I am not using
shadow passwords.

When the guest user is logged in it is treated as a regular user, even
though in the passwd entry for this user is:
user:password:527:508:whatever:/home/webmet/home/./user:/bin/fakeshell

when ftp'd in, a cd / goes to the root directory of the host, not
/home/webmet/home as it would seem.

When using 2.4[1] ls and dir wouldn't return anything, but mkdir and chmod
commands were working.

Anyone have any ideas on getting this to work?

TIA
Greg

Greg,
You need to create a group and associate the user with that group. In
/etc/ftpaccess (or whereever you put the ftpaccess file) you need to define
that group as a guest group.

The guest password entry should not be in the /etc/passwd in the anonymous
directory. Same with the group file.

You give two paths above; is it possible that there is some confusion
there?

/my/users/dir/

/my/users/d/dir/./

Ok, in the real system, /etc/passwd has a user entry that has
/home/webmet/home/./lies defined as the home directory, the shell is
a c program I wrote that simply says "you don't have telnet privileges" and
closes out. Quite simple really. That user is part of the group webmet
(group #508), as defined in /etc/group. In /etc/ftpaccess I have the line:
guestgroup webmet
and I also have private set to no (I dont want the users to change their
group with site group .. ) if this matters. In /home/webmet/home/lies I
have created a bin and etc directory. I have copied fakeshell (static
binary) and ls (static binary) to the bin directory. I've also created the
'fake' group/passwd file in the etc directory as per the guest howto. I
also created the .rhosts and .forward files, also as per the guest howto.

I've gone through everything step by step, as well as using the OReilly
Managin Internet Information Services book. It doesn't seem to be chrooting
properly.

Any more ideas I can try or check??

TIA
Greg

I am not 100% sure what you mean here. AIX by default implements shadow
passwords, since the passwords are stored in /etc/security/passwd and
not in /etc/passwd.

We run wu-ftpd here under AIX. For what I needed to do to get it
running, check out:
http://www.pcc.com/~jay/src/networking/wu-ftpd-2.4/ORIGINALS/
It's working fine, that I know of.

You dont need to implement shadowed passwords, IBM have done it already.

Make sure that in your /etc/shells you have add the shell of the real user
i.e. if your user have /bin/ksh the line /bin/ksh must be in /etc/shells.

Subject: guestgroup in AIX
Mime-Version: 1.0
Content-Type: text/plain; charset="us-ascii"

X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

I have install the wu-ftpd in an AIX 3.5
it works fine for normal use, but i have problem when i try to
use it for guestgroups ( for users that must have permission to ftp only)

An ftp only user logs in correctly, the root changes correctly to the home
directory, but the LIST command does not work.

Even with the full read-execute permissions of bin/ls i can't see the file list.

A dummy shell (/etc/ftponly) have been added in /etc/shells, the directory structure
have been as the anonyous ftp, etc...

I have also tried a dummy bin/ls and seems that bin/ls never called.

Does anyone know whats the solution (or what's the problem) ?

Thanks in advance.

Subject: chroot problem..
MIME-Version: 1.0

I setup a virtual ftp site and it works great. However, I need a user to
be able to access his own dir and manipulate its contents. I seem to
have set everything up correctly because when he logs in it says `User
hisusername logged in. Access Restrictions Apply`. However, the server
isn't doing a chroot! I have the passwd files that say /his/dir/./ but
that isn't working. I've built the appropriate bin and etc dirs...
What's not working...I'm happy to field questions as to certain
configurations, but I think I've done it all correctly... Is there a bug
in the beta-11 verion?

If it helps any, I tried to log onto the `real` ftp server and got the
message:
425 Can't create data socket (0.0.0.0,20): Bad file number.

Help!,

Alan,

If it's any consolation, I am seeing the same problem on my end when
I activate chrooting <g> .. If I remove work around the chroot, it
works fine. Looks to me like the remote IP is getting clobbered
somewhere..

Ali, read the FAQ and the guess howto:

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

ftp://ftp.academ.com/pub/wu-ftpd/private/wu-ftpd-2.4.2-beta-11.tar.Z

WU-FTPD FAQ: http://www.hvu.nl/~koos/wu-ftpd-faq.html

guest howto: ftp://ftp.fni.com/pub/wu-ftpd/guest-howto

There are additional security references in the above docs.
----Quote From M. B.-----

I'm guessing that you're using some SYSVr4 OS(Solaris?)
If you do a chroot you must provide in all the directories that
do a chroot() all the necessary lib, dev, etc..

lib/*
dev/*
etc/*

also for solaris

~ftp/dev/tcp must be 666

If not, the ftpd server will not be able to open the Data socket
hence the "425 Can't..."

Thanks for the speed reply... I tried to determine the libraries
required, but I was unable to do so.. :( You were correct when you
guessed that I was running Solaris 2.5 :) .. Any pushes in the right
direction would be greatly appreciated..

Regards,

Ali

P.S. The problem is still the 425 data connection ...

A) There's a gnu utility, I think it's ldd, that will tell you the
libraries required by an executable binary.

B) Give up and use the libraries that come in your standard anonymous ftp
/lib directory. These can usually be examined at your typical anonymous
ftp site. Maybe pick one running the same OS you are.

C) Poke at it with a stick. Start with the standard C library, libc, and
use the chroot command to test from there.

Been there done that... :) Placed all of the proper libs in the
proper places, created the dev/tcp and dev/zero files in the users
dir, now the connection is established, and then boom core dump..
yet i am able to upload to the user's dir.. just no ls.. I have also
tried the JEDIPATCH which implements an internal ls.. with the same
results.. any more ideas..

Thanks,

Ali

Well it seems so simple when I read the instructions, yet it doesn't work.
I complied with -DVIRTUAL added to the CFLAGS in the Makefile, and added
"virtual 10.10.10.10 root /export/home0/islands" to the ftpaccess. And
yes, I did change 10.10.10.10 to my IP. When I FTP in it will let me back
out to the root of the box and browse around.

Any suggestions? Solaris 2.5.1 Merry Christmas all and thanks mucho!

Note: You still have to anonymous ftp in to keep from browsing around.

Subject: Minimum password length 8 chars? [HPUX, 2.4.2beta11]
X-Mailer: Elm [revision: 109.18]
X-Listprocessor-Version: 7.1 -- ListProcessor by CREN

Hi all,

I am setting up wu-2.4.2-academ[BETA-11] on HP-UX 9.05 (HP's cc).
I used default settings #undef PARANOID, #undef SKEY, #undef SHADOW_PASSWORD.

I have spent a few hours trying to understand why everything
works fine for some users, while other users get
ftp> dir
200 PORT command successful.
150 Opening ASCII mode data connection for /bin/ls.
421 Service not available, remote server has closed connection
the first time they try to use 'ls' or 'dir' after they are
successfully connected.

The surprising answer is that things work well for user whose
password is at least 8 characters long, while those with 6
(our minimum) or 7 characters experience the problem above.
Interestingly, the problem is also present for user 'ftp',
while it disappears for user 'anonymous'.

Now, requiring massive amounts of users to change their password
is doable, but kinda of a nightmare for our user support people.
Is there some compilation or configuration trick to avoid this
bizarre problem, or am I the first to run into it?
Any suggestion is welcome, and Merry Christmas and Happy 1997
to everybody!

Is the -a option enabled in your inetd.conf?

Less files, less administration, easier upgrades, simpler setups --> less
security risks

As you can guess, I'm in favor of builtin ls. Of course, as an option,
those who would still like to use an external ls could define
-DEXTERNAL_LS.

I disagree. Adding a bunch more code to an already overcomplex daemon is
not a good thing to do. It makes porting just that more complex, as well
as adding yet another glob of code on top of everything else. There is no
way that makes things more secure.

I agree that a built-in ls provides less for most of us then it allows. I
wonder how much it would take to make that built-in ls into a seperate,
minimal, staticly-linkable, standalone ls. That should satisfy
everyone's requirements, right?

Any thoughts?

Trouble is, it dosen't make things substantially simpler. You still have
to have (minimally) /etc and have to have /bin and /lib if you want to
support the fancy tar and zip suff. And the
security/reliability/complexity problems are only pushed into the code
where they are harder to work with.

I'd opt for a configuration utility (script). You give it a directory and
it makes the directory anonymous ftp-able. Various options to
allow/disallow different bin utilities (would remove stuff from bin as well
as add). An option to supply a directory to be used as a "template". An
option to hardlink to the template directory's leaf nodes. An option to
"update" to make the target directory conform to a template or set of
command line specifications.

Is it do-able to have a "allow ls" option that knows what libraries ls
requires across different platforms? Or would each platform have to have
library info hardcoded?

On a slightly different note: I'd opt for _removing_ the class and
guestgroup stuff. tcpwrappers does a more through job of setting up
"classes". Pluggable components are better -- more widely used, more
options, less bugs, etc. You'd need a) a command line option to specify a
configuration file (I have a patch at ftp://ftp.meme.com/software/) b) a
configuration file directive to force a directory to chroot to as with
anonynmous ftp. I haven't thought this through. You'd probably want to
keep whatever keeps track of login names and just get rid of the network
layer class making. You could probably get rid of some other stuff as well.

I am running Version wu-2.4.2-academ[BETA-11](1) on a Sun Ultra2 with
Solaris 2.5. I would like to be able to issue the "user" command on the
command line in order to change to a different user while in ftp. (This
is possible with the Solaris ftp.)

However, when I try it with wu-ftp, I get the following:

cox2:/issc1/netscape/ns-home# ftp cox1
Connected to cox1.
220 cox1 FTP server (Version wu-2.4.2-academ[BETA-11](1) Mon Sep 30 18:00:18 MD
T 1996) ready.
Name (cox1:compoper):

Password:
230 User compoper logged in.
ftp> user root
530 Already logged in.
Login failed.
ftp> user notauser
530 Already logged in.
Login failed.

Is the "user" feature enabled in wu-ftpd? Or am I just doing something
wrong? Any suggestions would be greatly appreciated!

Thanks,

Hi,

I'm using Version wu-2.4.2-academ[BETA-11](1) with Solaris 2.5. I like to
have lots of info from ftpd in my syslog/xferlog, and so I have the following
set in /etc/inetd.conf:

ftp stream tcp nowait root /usr/sbin/wuftpd ftpd -Aiod

However, this is putting users' passwords into the syslog when they log in.
Is there any way around this while still using the "d" flag?

Any suggestions are appreciated!

Thanks,
Pete Ruprecht

I was hoping that the virtual ftp would allow users to log in and be
restricted to their directory, but they will be logging in using their user
name and pw, not anonymously. This seems to negate the virtual aspect. Is
there a way to allow users to be dumped into thier home directory and being
restricted to that directory? Thanks

ls, put and get command works well !! :-)

But, "dir" command is seemed working strange.

Phenomena)
It takes about 30 second to return "dir" result.
UID, GID appear numeric.

UID=100 and 0, GID=1000 and 1 is written in ~ftp/etc/passwd, group.

Question)
Why is numeric UID and GID appeared ?
Why does it take about 30 seconds to return "dir" result ?

Please inform me to solve this problem.

Thank you.

>From the Sun 'bugs' database:

====
Bug Reports document 1219594
Synopsis: ftpd manpage: interference between sublogins and /usr/sbin/nscd -
note needed

Manpage for in.ftpd should mention (in the NOTES section) that the
name service caching daemon /us/sbin/nscd might interfere with some
functionality of anonymous ftp. Namely, unless caching for passwd
is disabled in /etc/nscd.conf, a feature known as sublogin will
not work. Which is more a feature, than a bug ;)

[Sublogin takes place when user first logins as anonymous, and then issues
user xxx command - in order to become xxx, where xxx is a valid username
in the anonymous-ftp (chrooted) area (ie an entry for xxx exists in
~ftp/etc/passwd and not in /etc/passwd).]
====

You can disable passwd caching by nscd by putting

enable-cache passwd no

in /etc/nscd.conf, then kill and restart /usr/sbin/nscd.

(Just as the ftpd man page told you to...)

Check that you have 'files' in /etc/nsswitch.conf for passwd and group,
and that ~/ftp/passwd and ~/ftp/group have the values you want in them. If
you have nis or nis+ listed instead of files for passwd and group, then
the 30 second delay probably is a nameservice timeout.

Also check the ftpd man page again, for anything else you've missed.

yes, /home/ftp is in the NIS map and shared across platforms.
This will make it unworkable for anonymous.

I could :

1-
overide the mount points and override NIS locally
for each platforms
2-
Builtin ls.
Althougth I agree, wu-ftpd is a monster
3-
a hardcoded path for a statical link ls(from Karl Pinc)
"/bin/ls.ostype"

I've already got rid of 1), I'm looking at 2) and 3)
If you have any comments/suggestions I'll be happy
to hear them.

NOTE:
I don't wanna here about loosing gzip/tar etc ...
it's nonsense!! must packages are allready tarred and
gunzip... It's a waste of CPU cycles, especially when
two of my main Ftp servers are xferring 2 GIG a day.

as far as I know you may not use the user feature once you are logged in
as another user.
If I'm wrong then something is wrong with my ftpd too.

I saw man page and copied /etc/nsswitch.conf to ~ftp/etc.
But, It seems works strange.

Please check nsswitch.conf.

passwd: files
group: files
hosts: files dns
networks: files
protocols: files
rpc: files
ethers: files
netmasks: files
bootparams: files
publickey: files
# At present there isn't a 'files' backend for netgroup; the system will

netgroup: files
automount: files

Is it true ?

Thank you.

HI!

I'm trying to set up sublogins using WU-FTPD but I have found some
problems. After I had added entries in ~ftp/etc/passwd, and had created a
subdirectory that only people using the sublogin could access, I accessed
the FTP archive as normal, anonymous users, and then I tried to specify
the sublogin with the user ftp command, but the system answered that I
can't change to user from guest login.

Does someone have an ideia? What can I do?

TIA.

See ya.

I don't know if this has been reported or not. When i try to ftp into a
virtual server, if i put in my full e-mail address for the password to
anonymous i am let it.

If i put in just rob@ or just rob, i get an error 421 Service not available,
message. I had anonymous ftp set up to accept any response to the password
for the main ftp, but it apparently did not cascade to my virtual ftp. Is
there something i missed in the settings?

I am experiencing a syndrome where the password has to be at least
8 characters long , otherwise I get '421 Service not available'.
This is also true for anonymous ftp.

Your problem may be of a different nature, of course, but just
out of curiosity can you try using, for instance,'robrobrob'
as a password?

Hi all,

Unfortunately, disabling the nscd password cache doesn't clear up
my problem. Nor does killing the nsc daemon. Does anyone else see
the kind of behavior I describe below, or is it just me?

Thanks again,

Synopsis: ftpd manpage: interference between sublogins and /usr/sbin/nscd -

Manpage for in.ftpd should mention (in the NOTES section) that the
name service caching daemon /us/sbin/nscd might interfere with some
functionality of anonymous ftp. Namely, unless caching for passwd
is disabled in /etc/nscd.conf, a feature known as sublogin will
not work. Which is more a feature, than a bug ;)

I'm trying to prevent real users from uploading files with spaces and
characters beginning with . or -. Using the command below prevents any
file from being uploaded.

path-filter real /usr/local/etc/pathmsg ^[A-Za-z0-9]*$ ^. ^- \
^
(a space)

Can someone please tell me what I'm doing wrong.

Thanks.

Beta 11, using the "virtual ftp" feature, chroot's to the virtual chroot dir
for both anonymous and guest users, regardless of passwd file entries.

I consider this a bug, personally, but this is open to opinion on how virtual
ftp servers should operate. I patched Beta-11 to use the passwd /./ directory
preferentially over the virtual ftp chroot dir.

Here is my patch (previously posted) to fix this:

this "^." will match anything and everything
try:
^\.

^[-.].*$

secondo)
^[A-Za-z0-9]*$ is plain wrong

Hi all,

I was recently having problems using the "user" command to switch to
a different user when already logged in. To fix this, I commented
out the following lines from the source code for wu-ftpd-2.4.2b11
(ftpd.c):

/* H* fix: if we're logged in at all, we can't log in again.
if (logged_in) {
reply(530, "Already logged in.");
return;
} */

Works fine now.

Hi all,

I was recently having trouble with password appearing in the syslog
when using wu-ftpd-2.4.2b11 in -d (debug) mode. To fix that I modified
ftpcmd.y to include the following lines:

if (debug){
if (strstr(s,"PASS") != NULL)
syslog(LOG_DEBUG, "command: %s", "password");
else
syslog(LOG_DEBUG, "command: %s", s);
}

Maybe you will find this useful.

I'm sure this question has been asked before, but I can't seem to find
the archive to this mailing list. I compiled wu-ftpd just fine, but
when I do a 'build install' I get errors concerning usage of the install
command. I sure could use the help!

Thanks in advance,

If you are going to post this type of thing, please save the original
file, modify a copy, and do a 'diff -u oldfile newfile > patchfile'. Then
post the patchfile. Otherwise examples below are ambiguous and can cause
people to patch the wrong thing and thus introduce more/worse errors.

Pardon me, but ... I believe this was
one of the many security fixes done by
Hobbit(H*): to disallow "re-login", port fix, pasv fix, etc ..
see FIXES*-HOBBIT

There was a healthy thread on bugtraq|best-of-security
on this issues and the exploits.

Well if you know what you're doing ... that's fine.
Just wanted to bring it to your attention, no
malice intended.

bye, bye

There are two different archives. A pointer to both is in the FAQ for the
current versions of wu-ftpd, which also has the following item :

10. install fails with 'install: ..'

The makefile is setup for the bsd version of the install program. Some
OS'es (including Solaris) use the svr4 version. In that case set in the
makefile :

INSTALL = /usr/ucb/install

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

O.K... I realize that this has been answered more than once, but I can't
find th email that has one consice answer... So, what does one do if they
receive the error:
425 Can't create data socket (0.0.0.0,20): Bad file number.

Secondly, Is there a way to have more than one guest group?

Hey there. We've been poking around trying to understand why wuftpd uses
so much RAM on our Solaris box. It appears that the recursive use of
tglob()/ftpglob() uses around 500K on the stack. Since it's all mostly used
when someone does a "ls -l", it all pages back in to service the next ls
command. Since we run a fairly high traffic FTP server, the 2MB or so
footprint of wuftpd is rather painful.

Has anyone tried replacing wuftpd's internal globbing code with calls to
the glob and globfree system calls under Solaris (and linux I believe,
etc)? Perhaps the system glob() is more memory efficient.

If anyone has tried that and has a patch, we'd be very happy to try it
out here. :)

Thanks,

-Jonathan

Hi,

I managed to install the beta11 on my Linux box after following the FAQ.
BUT a couple of things doesn't seem to work:

1) The "Please read the README file. It was changed *** days ago" doesn't
work anymore for any file.
This is still configured in /etc/ftpaccess as
readme README* login
readme README* cwd=*

2) It also doesn't read the welcome.msg files. Again this is also defined
in /etc/ftpaccess.

Other than that, it compiles with shadow support and works great!

Also, I would like to ask whether HTML tags could be read in either the
README or welcome.msg files
so that it could pass through a web browser as links. I tried it and it
doesn't work. Any ideas?

Thanks in advance,

Ahmad

How do I do this?

I tried to compile wu-ftpd under AIX 4.2 and got these results:

Craig, I just went throught the same thing on my AIX 4.2 and AIX 4.1.3
systems. I got some suggestions from people on the list.
They were to use Beta 11 which has the
"ftpcmd.y", line 371.18: 1506-045 (S) Undeclared identifier cmdtab.
"ftpcmd.y", line 383.26: 1506-045 (S) Undeclared identifier sitetab
fixed.

The vers.o problems were fixed by using GNU make.

The other errors don't seem to matter. The Beta version puts the ftpd in
/etc and the other files in /usr/local/lib/ftpd/... You can edit the
Makefile after the build to change some of the paths. The the
src/pathnames file is different. Everthing seems to run fine but I have a
lot of tesing to do.

BTY, I used xlC version 3.1.4 for the compiles.

Good luck. WU-ftp is worth the effort.

Larry

That patch has nothing to do with this.

It doesn't hurt if /etc/ftponly does not exist.
It does need to be listed in /etc/shells though.

Thom, The guest account instructions talk about 2 options for this.
1) change the /src/ftpd.c file to int use_accessfile = 0; to int
use_accessfile = 1;

or

2) use the -a flag in the /etc/inetd.conf file when starting ftpd
BTY: there are other options you can use there also.

-L log user commands to syslog file
-i log incoming (uploaded files) to the xferlog
-o log outgoing (downloaded files) to the xfer log
-a enables the access file
-A disables the access file
-d sends debugging info to syslog

These are in the nutshell book.

hope this helps.
