The hosts file is used by the operating system to map hostnames to IP addresses. To set the hostname, one needs to modify the hosts file. The hosts file contains lines of text consisting of an IP address in the first text field followed by one or more host names.

For Linux

To edit the hosts file present in the etc folder, perform the following actions:

1. To open the /etc/hosts file, open the terminal, switch to superuser and use the command:

   Code Block
   gedit /etc/hosts

2. In the hosts file that gets opened, locate your old hostname, which resembles one of the below lines:
   1. <ip_address> <your-old-hostname> <your-old-hostname>.<domain>
   2. <ip_address> <your-old-hostname>
       
3. Replace the old hostname with the correct hostname and save the hosts file.
   
   

4. In the terminal, type the following:

   Code Block
   hostname <new hostname>

5. To see if the hostname has been set properly, use the following command:

   Code Block
   hostname -a
