1. To get started, press Ctrl – Alt – T on your keyboard to open the Terminal. Next, type the command below to open the hostname file.
2. Type this commande into the terminal and remember that the current computer name is @aymen-Aspire-E1-571

3.   Then change the name to whatever you like and save the file.

4. Next, while command console is still open, type the command below to open the hosts file.

gksu gedit /etc/hosts

5. Finally, change the name shown to complete the change and save the file.

6. Close all open windows and restart your system.
