Shalom filesystem,

You change the hostname by editing the following file:

vi /etc/sysconfig/network

NETWORKING=yes
HOSTNAME=cleartux

You can set GATEWAY and NIS invormation there as well.

Then:

service network restart

hostname
# to check the change worked.

In steps described by Steven the King you'd still see the old hostname (until reboot).
If you want the hostname to change without reboot do in addition to suggested by Steve:
echo newhostname > /proc/sys/kernel/hostname


Best regards.

You can edit /etc/sysconfig/network and change the hostname.

You can use

hostname newhostname

To set the new hostname immediatly

You must also ensure that the /etc/hosts file reflects the changes.
