It's not too hard. Use the following command in a terminal: sudo hostname your-new-name This will set the hostname to your-new-name until you restart. See man hostname and How do I change the computer name? for further information. Note After a restart your changes in /etc/hostname will be used, so (as you said in the question), you should still use sudo gedit /etc/hostname (or some other editor) so that file contains the hostname. You should also edit /etc/hosts and change the line which reads: 127.0.1.1 your-old-hostname so that it now contains your new hostname. (This is required otherwise many commands will cease functioning.) share improve this answer
