Setting Hostname Permanently From GNOME Settings

Step 1: Open Settings

Open the Applications menu and search for the “About” option then, open it. You will find various settings such as Device Name, Memory, etc.

Step 2: Rename the Hostname

Click the arrow mark next to the Device Name. A window will appear, allowing you to rename the device. Rename it accordingly. We are changing our machine’s hostname from “Ubuntu” to “w3wiki.”

Step 3: Restart

Save the new hostname by clicking “Rename,” and the hostname is permanently changed to the new name, here it is changed to “w3wiki.” Restart the machine to ensure the new hostname is set.

Note: Changing the hostname from GNOME settings may not take effect immediately, so a restart of the Linux machine is necessary. This method is not always reliable.

Setting a hostname is a fundamental step in configuring a Linux system. The hostname acts as an identifier for your machine on a network, making it easier to manage and communicate with other devices. In this article, we’ll explore the importance of having a well-defined hostname and the process of setting it permanently in a Linux environment.

A hostname not only gives the recognition of your system but also has a crucial role in networking. Whether you’re on a local network or the internet, you should have a clear and identifiable hostname for the administration of your Linux machine.

You can set a temporary hostname using the hostname command while a permanent hostname configuration stays the same even after reboots. This article lets you know how to configure a permanent hostname, understand the relevant configuration files, and the necessary steps to apply the changes.
