Introduction

In the vast realm of networked computers, each device needs a unique identifier—a name that allows it to be distinguishable from the crowd. This unique identifier is known as the “hostname.” Whether you are working in a large corporate network or simply tinkering with a personal Linux box, you might find yourself needing to change this hostname at some point. This comprehensive guide walks you through the process of changing the hostname in Debian 12 BookWorm, one of the latest iterations of the popular Linux distribution Debian.

Prerequisites

Before diving into the nitty-gritty, ensure you have the following:

1. Access to a Terminal: You can access the terminal through your GUI or via SSH if you’re working remotely.
2. Superuser or sudo Privileges: Administrative access is necessary to make system-wide changes.
3. Basic Understanding of Linux Command Line: Knowing how to navigate the terminal will be beneficial.
4. Installed Instance of Debian 12 BookWorm: The instructions are tailored for this specific version.

Terminology

To make sure we’re on the same page, let’s clarify some terminology:

1. Hostname: A label assigned to a machine on a network.
2. Superuser: The administrator with full access to the Linux system.
3. sudo: Command that allows permitted users to execute a command as a superuser.
4. /etc/hostname and /etc/hosts: Configuration files storing hostname information.

Backup Current Settings

It’s always prudent to backup important configurations before making any changes. Open the terminal and run:

cp /etc/hostname /etc/hostname.bak cp /etc/hosts /etc/hosts.bak

This creates backup copies of your current hostname and hosts files.

Method 1: Using the hostnamectl Command

Step 1: Check Current Hostname

To see your current hostname, run the following command:

hostnamectl

Step 2: Change the Hostname

To change your hostname, execute:

sudo hostnamectl set-hostname new-hostname

Replace new-hostname with your desired hostname. For instance, to change the hostname to “mydebian,” you’d run:

sudo hostnamectl set-hostname mydebian

Step 3: Verify the Changes

Use the hostnamectl command again to check if the hostname has been updated:

hostnamectl

Introduction

In the expansive universe of Linux distributions, the choice of which one to use can be overwhelming. Among the galaxies of options, two Arch-based stars have shone increasingly brightly: Manjaro and EndeavourOS. Both are rooted in the Arch Linux ecosystem, yet they cater to different kinds of users and offer unique experiences. If you’re currently a Manjaro user contemplating the switch to EndeavourOS, this article aims to help you make an informed decision.

Background Information

What is Manjaro?

Manjaro is an Arch-based Linux distribution that is designed to be user-friendly and accessible. Known for its ‘Install and Go’ philosophy, Manjaro offers ease of use, making it suitable for Linux newcomers. It comes with a variety of desktop environments like XFCE, KDE, and GNOME, among others. Manjaro also features its own package manager, Pamac, which makes software installation a breeze. Automatic updates and built-in stability checks make it a go-to choice for those who want the power of Arch Linux without its complexities.

What is EndeavourOS?

EndeavourOS is also an Arch-based Linux distribution, but it aims to be closer to vanilla Arch. Targeted at intermediate to advanced users, EndeavourOS offers an almost bare-bones experience with the choice to customize your system as you see fit. While it does come with an installer, it is more manual compared to Manjaro’s Calamares installer. It aims to provide the user with an Arch experience with minimal added features, relying mostly on the Arch User Repository (AUR) and Pacman for package management.

Comparison Criteria

To make an apples-to-apples comparison between Manjaro and EndeavourOS, we’ll evaluate them based on the following criteria:

• Ease of Installation
• Package Management
• Desktop Environments
• System Performance
• Software Availability
• Community Support
• Stability and Updates

Detailed Comparison

Ease of Installation

Manjaro offers an incredibly user-friendly installation process via its Calamares installer. It is mostly automated and requires only minimal user interaction.

EndeavourOS, on the other hand, offers a more hands-on installation process. Though it also offers an installer, it allows for more customization during the setup, which might be more appealing to advanced users but intimidating for beginners.

Package Management

Manjaro uses Pamac for package management, which offers a clean, easy-to-use graphical interface. It also supports AUR, enabling a wide range of software availability.
