warning in /var/log/messages

Actually, it seems that you are running bind on your system and you have
defined to Host names ("A" records) to the same ip address. Only one host
name should be assigned to ip address within bind and any other names that
you wish to use for this computer should be "CN" aka alias records.

The real cause of your error message in the syslog is related to running the
'auth' service within inetd.conf (comment the auth service out and send a
SIGHUP command) and then the identd service runs on its own pid.

The greater minds on this message base might want to convince you either to
1 - remove/disable auth from inetd or
2 - disable auth aka identd altogether

I would be interested in any comments that some might have regarding the
usefulness / necessity / security implications of running identd/auth
services. The book on Linux/OpenBSD firewalls that I just finished definitly
recommended to extinguish this service and to specifically REJECT (using
IPCHAINS) attempts to connect to this port so mail servers etc don't hang
you out to dry while waiting for a reply.
