what is output of?

cat /etc/sysconfig/network

Craig

Ooops....


[root@bogon log]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=localhost.localdomain

sounds as if the name is attached to either:
- NetworkManager and since I don't use it, I don't know where it might
store supplemental settings...
- the configuration of the device itself
- in some script that sets the name somewhere.

is this system using DHCP to get its ip address?
if so, what is ouput of...
/etc/dhclient-eth0.conf

I think that if the hostname is 'reset', it should be reflected in
syslog...
what is output of...
grep Host /var/log/messages

Might it be set in /etc/rc.d/rc.local?
tail /etc/rc.d/rc.local # should look very much like this and anything
# additional might be a script that sets it
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
