Description Nicolas Mailhot 2003-12-16 05:36:50 EST
Yesterday's rawhide sync killed dhclient here and as a result I lost
the network. Since all users are in ldap+krb+nfs home this means they
could not be used.

However root is *not* a network user, it's a local one exactly for
this reason (ie fixups when network is AWOL), and it saved the day in
the past.

This time the root account was dead. I had to restart in single mode,
and switch the eth entry to fixed address, then restart network before
root was allowed to log in again.

Dan, would you look into this? I suspect it has something to do with
the SELinux patches.
Comment 3 Daniel Walsh 2004-01-15 14:48:25 EST
Maybe, but SELinux should be turned off if they are not running a 2.6
kernel with a loaded policy.  What is being reported in /var/log/messages?
Comment 4 Nicolas Mailhot 2004-01-15 15:02:58 EST
Well, obviously I didn't test killing the box every day since I filled
this bug;). I'll try to reproduce it tomorrow when I have access to
the system.

I reproduced it today after a new rawhide sync (since dhcp was fixed I
yanked the network wire). Attached is the full /var/log/messages for
this boot. Local root login was attempted thrice, but does not even
seem to be registered in the logs.

I don't think this is SE Linux. I think it's the long-standing problem
with the pam auth file. In other words, this is a dup of bug #55193,
from 2001-10-26.
