Changing the hostname on Debian Linux

How to change hostname on Debian Linux

The hostname of a Linux system is important because it’s used to identify the device on a network. The hostname is also shown in other prominent places, such as in the terminal prompt. This gives you a constant reminder of which system you’re working with. It’s a real life saver when you’re managing multiple systems through SSH and those command line terminals start to blend together in your mind.

Of course, IP addresses are used when devices need to communicate with each other, but those can change frequently. Hostnames give us a way to know which device we’re interacting with either on the network or physically, without remembering a bunch of numbers that are subject to change. Thus, it’s important that your system bears a hostname which helps you to identify it quickly. For example, “backup-server” is much more informative than “server2.” If you can’t easily identify a system’s purpose from the hostname, it’s time to change it.

In this guide, we’ll show you how to change the hostname on Debian Linux. Changing the hostname can be done either by command line or GUI, and we’ll show you the steps for both methods below.

In this tutorial you will learn:

  • How to change the Debian hostname from command line
  • How to change the Debian hostname from GNOME GUI

Using apt search to find relevant packages

How to use apt search Linux command

Installing packages is really easy. That is, as long as you know the name of what you’re trying to install. If you don’t, then you can always search for installable packages. On distros that use the apt package manager, like Debian, Ubuntu, and Linux Mint just to name a few, this is done with the apt search command.

In this guide, we’ll show you how to use the apt search command with multiple examples. You’ll quickly learn to master the task of finding packages to install.

In this tutorial you will learn:

  • How to install Debian in “advanced-mode”
  • How to load the installer additional modules needed to unlock an existing LUKS device
