Changing the hostname on your machine

This can be achieved in three steps.

1) Issue the command :

root# hostname new-host-name

2) Change the network configuration file /etc/sysconfig/network to include the line :

HOSTNAME=new-host-name

3) Restart the systems which relied on the hostname (or reboot):

root# service network restart

Restart desktop

i) Bring down system to console mode :

root# init 3

ii) Bring up X Windows:

root# init 5

One may also want to check the file /etc/hosts for an entry using the system name which allows the system to be self aware.
