How to Change the Hostname of Ubuntu Server ?

We can change the hostname of a machine by several ways. I am mentioning one way to change the hostname of Ubuntu server.

  1. Open the terminal or Login with putty.exe as root user (if you are working remotely)
  2. Goto /etc/
  3. Type nano hostname
  4. Change the HOSTNAME to your preferred machine name
  5. Press Cntrl+X
  6. Save the configuration by pressing Y
  7. Log off or reboot

Note: Add the new hostname and ipaddress in the /etc/hosts file also
