Does the user exist in /etc/passwd?

telnetd:x:104:104::/nonexistent:/bin/false

The telnetd user should work in inetd.conf:

telnet stream tcp nowait telnetd.telnetd /usr/sbin/tcpd
/usr/sbin/in.telnetd

Mark,

Yes, telnetd is in /etc/passwd. This is strange.

Ok. In /etc/hosts.allow:

ALL: 127.0.0.1

Stop and restart network services. Can you now telnet localhost?

Regards,

Mark.

Mark,

It didn't make a difference. I think the problem is the telnetd
server process was never launched because inetd doesn't recognize
telnetd as a valid user. Recall in my first post about the syslog
message. The exact message is: gumby inetd[614]: telnet/tcp: No
such user 'telnetd.telnetd', service ignored. I don't see a telnetd
process running.

My passwd entry is: telnetd:x:103:103::/nonexistent:/bin/false

My group entry is: telnetd:x:103:

Like I said, I can get it running if I change inetd.conf to have root
as the user, but I shouldn't have to (it wasn't that way on my older
Debian install).

Ok, lets check some file ownerships and permissions:

ls -l /usr/sbin/in*

-rwxr-xr-x 1 root root 22720 2006-02-07 02:21 inetd
-rwxr-xr-x 1 root root 35940 2005-10-09 17:24 in.telnetd

ls -l /usr/lib/telnetlogin

-rwsr-xr-- 1 root telnetd 6032 2005-10-09 17:24 /usr/lib/telnetlogin

Note: suid

> My passwd entry is: telnetd:x:103:103::/nonexistent:/bin/false
> My group entry is: telnetd:x:103:

Check that they also exist in shadow and gshadow.

grep "telnet" /etc/services

telnet 23/tcp
telnet 23/udp

cat /etc/hosts.allow

ALL: 127.0.0.1

Is inetd running as root?

ps -ef|grep "inetd"
root 21241 1 0 Feb26 ? 00:00:34 /usr/sbin/inetd

Try adding "-a none" to telnet command in inetd.

Try running the telnetd and -D debugging options. I believe that you can use
sudo to run an user telnetd.

There may be some issues with PAM modules, but I don't know much about these.

Regards,

Mark.

Mark,

I appreciate all your help. I tried most of your suggestions last
week--I still haven't tried the "-a none" option though. I've been
busy getting the rest of my system up (lirc, irmp3). Since it works
OK with root as the owner, I'm gonna leave it for now. I don't have
that linux box routed to the internet, so it's not really a big deal.
I just wanted to fix it for the sake of learning. I'll try your last
suggestion, and if it doesn't work, I'll periodically do a newsgroup
search to see if anyone else has the problem/solution.

Thanks again!


Jim
