If you are new to linux you probably will wonder how to change the hostname of your computer or server. (A hostname is the unique name by which a network attached device is known on a network.) If you enter the wrong hostname during the installation, and you need to change the hostname, here is the solution:-


  • Edit file /etc/sysconfig/network using your favourite editor. In my case is nano. So i’ll enter  nano /etc/sysconfig/network
  • Look for HOSTNAME=xxxxxx
  • Change the xxxx to the name you wish to set for your computer. (ex: HOSTNAME=wiredgorilla.com)
  • Save the file and restart the xinetd service. (ex: type service xinetd restart in your shell)
  • Done! You have just changed your hostname in Linux platform
