    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 :

    HOSTNAME=new-host-name

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

    root@srv# service network restart

    Restart desktop

    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.
