Hi!

One of our 3000/800-servers has started to behave very strange. We can't login.
When trying telnet the connection is just closed, and when trying rlogin it
reports "Can't open /var/adm/lastlog". I managed to get in using rsh and got
to root using a setuid shell.

When someone tries to login this message is logged in the syslog:
Jan 10 11:57:39 lane login: audgen(LOGIN): Permission denied
Jan 10 11:57:42 lane login: audgen(LOGIN): Permission denied
Jan 10 11:57:42 lane login: LOGIN FAILURE

When running ps no processes are reported. There are 45 processes on the
machine when looking in /proc. The system is a NFS-server, NFS is working.

A reboot did not solve the problem and nothing was reported during the reboot.
It was booted on /vmunix.

What has happend? We are not aware of any changes made to the system.

The machine is a 3000/800 running 3.0B of OSF/1. We are not running
C2-security.

/Mats
