• Set the host name in the /etc/hostname file:
  ?

  echo "ubuntu.example.com" > /etc/hostname

• Using any text editor, edit the file /etc/hosts so that the hostname points to the localhost address:
  ?

  127.0.0.1       localhost 127.0.1.1       ubuntu.example.com localhost    # The following lines are desirable for IPv6 capable hosts ::1     localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts

• Invoke the host name initialization script(if following command not work, you can reboot system).
  ?

  start hostname
