Changing the hostname of a Linux machine
This can be achieved in three steps.
1) Issue the command :
root@srv# hostname new.host.name
2) Change the network configuration file /etc/sysconfig/network to include the line :
3) Restart the systems which relied on the hostname (or reboot):
root@srv# service network restart
i) Bring down system to console mode :
root@srv# init 3
ii) Bring up X Windows:
root@srv# 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.
