Description Nicolas Mailhot 2003-12-16 10:36:50 UTC 
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.

Comment 2 Elliot Lee 2004-01-15 19:31:16 UTC 
Dan, would you look into this? I suspect it has something to do with
the SELinux patches.
Comment 3 Daniel Walsh 2004-01-15 19:48:25 UTC 
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 20:02:58 UTC 
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.

Comment 6 Nicolas Mailhot 2004-01-16 09:27:02 UTC 
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.
Comment 7 Matthew Miller 2004-03-30 14:57:55 UTC 
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.
