For all those that have been following this thread with bated breath ...
We dropped the RH 7.1 "login" binary onto the RH 7.3 system, and voila !! Problem solved.
Guess this is rather nasty solution, but so far it has not bitten us (yet) ?

Hello again,
For what it is worth, RedHat 7.1 does not display this behavior, but 7.2 (and 7.3) do ...

Subject: corrupt /var/run/utmp - telnet/rlogin
Hello
I have the following problem on Redhat Linux 7.3. Using console login, telnet and rlogin seems to corrupt the /var/run/utmp file. This results in incorrect information supplied by "w", finger etc. This problem does not happen when using ssh, to connect to the system.
The session below shows a repeatable scenario:
==> Two telnet session are connected (w, last and utmp are fine ...)
[branch@relinux branch]$ w
9:05am up 5 min, 2 users, load average: 0.00, 0.03, 0.00
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
branch pts/1 jvergeer 9:05am 0.00s 0.03s 0.00s w
branch pts/0 jvergeer 9:04am 31.00s 0.01s 0.01s -bash
[branch@relinux branch]$ last | grep still
branch pts/1 jvergeer Tue Oct 8 09:05 still logged in
branch pts/0 jvergeer Tue Oct 8 09:04 still logged in
[branch@relinux branch]$ last -f /var/run/utmp
branch pts/0 jvergeer Tue Oct 8 09:04 still logged in
branch pts/1 jvergeer Tue Oct 8 09:05 still logged in
reboot system boot Tue Oct 8 08:59 (00:05)
utmp begins Tue Oct 8 08:59:38 2002
==> Now we login on the console ...
[branch@relinux branch]$ w
9:05am up 6 min, 2 users, load average: 0.08, 0.04, 0.01
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
branch tty1 jvergeer 9:05am 4.00s 0.02s 0.02s -bash
branch pts/0 jvergeer 9:04am 1:11 0.01s 0.01s -bash
==> pts/1 is "lost" although the telnet session is still active
[branch@relinux branch]$ last | grep still
branch tty1 jvergeer Tue Oct 8 09:05 still logged in
branch pts/1 jvergeer Tue Oct 8 09:05 still logged in
branch pts/0 jvergeer Tue Oct 8 09:04 still logged in
==> "last" has the correct information, but utmp has been broken
[branch@relinux branch]$ last -f /var/run/utmp
branch pts/0 jvergeer Tue Oct 8 09:04 still logged in
branch tty1 jvergeer Tue Oct 8 09:05 still logged in
reboot system boot Tue Oct 8 08:59 (00:06)
utmp begins Tue Oct 8 08:59:38 2002
[branch@relinux branch]$
This happens with a standard RH 7.3 "server" build. I have applied all the updates for 7.3 and installed the 2.4.18-10 kernel. No luck ...
Has anyone else seen this problem ? Is there a work around (apart from using ssh) ?
Thanx for any pointers !
Regards
Johnny Vergeer
