To change your hostname do this:
First, exit X by dropping to rnlvl3:
Set /etc/sysconfig/network to:
Code:
HOSTNAME=newname.localdomain
Set /etc/hosts to:
Code:
127.0.0.1 localhost.localdomain localhost newname
Finally, reboot and your new hostname will be changed. (Look for a "setting hostname" message when PC boots up.)
