The hostname is the name that identifies a system on a network. By default, Ubuntu assigns a hostname to your system during the installation process. However, you may need to change the hostname to something more meaningful or unique. In this guide, we will show you how to change the hostname on Ubuntu 11.10.
Step 1: Open the Hostname File
The first step is to open the hostname file in a text editor. Run the following command:
sudo nano /etc/hostname
This command will open the hostname file in the nano text editor.
Step 2: Change the Hostname
In the hostname file, you will see the current hostname of your system. You can change it to a new hostname by replacing the old hostname with the new one. Once you have changed the hostname, save the file by pressing Ctrl + X, then Y, and finally Enter.
Step 3: Update the Hosts File
Next, you need to update the hosts file to reflect the new hostname. Run the following command:
sudo nano /etc/hosts
In the hosts file, you will see a line that starts with 127.0.0.1 and contains the old hostname. Change the old hostname to the new one and save the file by pressing Ctrl + X, then Y, and finally Enter.
Step 4: Restart the Hostname Service
Finally, you need to restart the hostname service to apply the changes. Run the following command:
sudo /etc/init.d/hostname restart
Now, when you run the hostname command, you will see the new hostname that you have set.
Commands Mentioned:
- sudo nano /etc/hostname – Open the hostname file
- sudo nano /etc/hosts – Open the hosts file
- sudo /etc/init.d/hostname restart – Restart the hostname service
