Configuring an APT proxy server in a Debian Linux environment can significantly enhance your network’s efficiency by caching package downloads. This setup is particularly beneficial for networks with multiple Debian or Ubuntu systems, reducing bandwidth usage and speeding up package installation. Apt-Cacher NG is a popular, easy-to-use APT proxy solution that we will focus on in this guide.

In this detailed guide, we will explore the process of converting a VirtualBox OVA file to the QCOW2 format, a necessary step for deploying virtual machines in a QEMU/KVM environment. This conversion is essential for users looking to transition from VirtualBox to a more scalable and open-source virtualization option like QEMU/KVM. We’ll cover each step of the process, from exporting your VirtualBox machine to finally deploying it on QEMU/KVM.

Virtualization technology has become an indispensable tool in software development, testing, and deployment. It allows you to run multiple virtual machines (VMs) on a single physical machine, each with its own isolated operating system and resources. This tutorial focuses on setting up a virtualization environment on Debian or Ubuntu Linux using QEMU, KVM (Kernel-based Virtual Machine), and Virt-Manager.

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.
