Kali Linux is one of the many operating systems that has full support for the Raspberry Pi, thanks to the ARM installer images. Combining Kali with a Raspberry Pi essentially gives you a portable penetration testing machine. Kali Linux can be installed and run without a monitor, keyboard, or mouse, so you will not need to worry about plugging in any peripherals to the Raspberry Pi.

A Raspberry Pi, especially the newer models, possesses all the necessary hardware power for running a dedicated Minecraft gaming server. While it is easy enough to host the game off your desktop computer while simultaneously playing, having a dedicated server allows you to host an uninterrupted Minecraft session that can stay up and running for longer periods of time.

Whether you’re a seasoned Ubuntu user or new to the operating system, understanding how to manage your system’s timezone is essential for ensuring that your computer’s clock is accurate, which is crucial for many applications and tasks. Adjusting the timezone in Ubuntu can be done through both the Graphical User Interface (GUI) and the Command Line Interface (CLI), allowing users flexibility based on their preference or needs.

Welcome to the comprehensive guide on installing and running GPT4All, an open-source initiative that democratizes access to powerful language models, on Ubuntu/Debian Linux systems. Whether you’re a researcher, developer, or enthusiast, this guide aims to equip you with the knowledge to leverage the GPT4All ecosystem effectively.

When managing an Ubuntu 24.04 system, it’s essential to understand the security and administrative practices that come with it. By default, Ubuntu does not set a root password and encourages the use of the sudo command for administrative tasks. This approach enhances security by limiting the use of the root account. However, there are scenarios where having a root password is necessary.

Cloud gaming is transforming the way we think about video games, offering flexibility and convenience by streaming games directly to our devices. One of the leading platforms in this revolution is NVIDIA’s GeForce NOW, which allows gamers to play their favorite games on virtually any device, including Ubuntu/Debian-based Linux systems.

Changing the hostname of your Ubuntu 24.04 server or desktop is an important task that can help in easier identification of your system within a network. The hostname is essentially the name that your computer uses to identify itself to other devices on the network. This guide will walk you through the process of setting or changing the hostname on Ubuntu 24.04.

Configuring a static IP address on your Ubuntu server is essential for various reasons, such as ensuring consistent network configuration, facilitating server management, and improving network security. Ubuntu 24.04, like its predecessors, uses the Netplan utility for network configuration, which simplifies the process of setting a static IP address through YAML configuration files.

Secure Shell (SSH) is an essential protocol for securely accessing networked machines remotely. SSH offers a secure channel over an unsecured network, providing strong authentication and encrypted data communications between two computers connecting over an open network such as the internet. Ubuntu 24.04, like its predecessors, supports SSH for remote administration, file transfer, and more. This guide will walk you through the process of enabling SSH on your Ubuntu 24.04 system, ensuring secure and remote management capabilities.

Support for the Internet Protocol version 6 is available on Linux since 1996. The kernel implements this functionality, which is usually active and enabled by default on all the major distributions, via the “ipv6” module. Sometimes, for various reasons, it may be desirable to temporarily or permanently disable IPv6 networking. In this tutorial we learn how to temporarily or permanently disable IPv6 networking on Linux, using sysctl, NetworkManager, or kernel command line arguments.

Some notebooks firmware allow setting start and stop battery charge thresholds. This feature can be really useful to increase the battery lifespan: if we use the notebook attached to the AC most of the time, we may want to set a low charge values, to avoid charging and keeping the battery at its maximum capacity; if we are using the notebook on the go, instead, we probably want to set higher threshold values to maximize runtime hours.

Ubuntu 24.04 LTS represents the cutting edge of open-source operating systems for both development and production environments. Docker, on the other hand, simplifies the deployment of applications inside software containers, making it an essential tool for modern developers. Combining Docker with Ubuntu 24.04 LTS can significantly streamline your development workflow. This tutorial aims to guide you through the process of setting up and running an Ubuntu 24.04 LTS Docker container on your machine.

LVM (Logical Volume Manager) is a technology which allow us to create a layer of abstraction over physical storage devices, and implement flexible partitioning schemes where logical volumes are easier to shrink, enlarge or remove than classical “bare” partitions. While LVM “thick” provisioning requires the allocation of a fixed amount of storage space to a LVM logical volume at creation time, by using “thin” provisioning, storage is allocated only when needed.

Welcome to our comprehensive guide on installing the KDE desktop environment on Ubuntu 24.04. KDE, also known as the K Desktop Environment, is a free and open-source desktop environment known for its customization, rich feature set, and a vibrant community of users and developers. Whether you are a long-time GNOME user looking for a change or you are setting up a new Ubuntu installation and prefer KDE, this tutorial will walk you through the installation process step by step.

While in the first part of this series dedicated to the Proxmox backup server we saw how to install the distribution, and in the second we explored the web administration interface, in this third tutorial, we learn how to create and restore a backup of a physical host using the Proxmox backup client.

In the evolving landscape of Linux distributions, the comparison between Ubuntu 24.04 LTS “Noble Numbat” and its predecessor, Ubuntu 22.04 LTS, emerges as a topic of keen interest for users and developers alike. This article delves into the key differences, upgrades, and enhancements that mark the transition from Ubuntu 22.04 to Ubuntu 24.04, offering insights into what users can expect from the latest iteration of one of the most popular Linux distributions.

In this detailed tutorial, we will guide you through the process of setting up a LAMP (Linux, Apache, MySQL, PHP) server on Ubuntu 24.04. This setup is crucial for hosting dynamic websites and web applications. We will cover everything from installing the necessary packages to securing your MySQL installation and testing your setup.

Linux users and system administrators alike are always trying to squeeze as much performance as possible out of their system. A big bottleneck for system performance frequently comes from file transfer speeds – that is, system read and write times. Although recent disk technology like SSDs (Solid State Drives) and NVMe (Non Volatile Memory Express) have sped up transfer times significantly over traditional hard drive disks, none can measure up to the speedy performance of a RAM disk.

Maintaining accurate system time is crucial for various network operations and synchronization tasks. In Ubuntu 24.04, setting up the Network Time Protocol (NTP) ensures your system clock remains synchronized with internet time servers. This guide provides a detailed walkthrough on configuring NTP on Ubuntu 24.04, ensuring your system’s timekeeping is precise and reliable.

Ubuntu, a popular Linux distribution, is widely used for its stability, security, and user-friendly interface. As you manage users on your Ubuntu 24.04 system, you might encounter situations where you need to grant administrative privileges to certain users. This guide focuses on how to add a user to the sudoers list in Ubuntu 24.04, a crucial step in managing user permissions and system security.
