Linux systems are often configured with strict password policies to ensure security, including enforcing minimum password length requirements. However, there may be scenarios where you want to allow shorter passwords, such as for testing environments or specific user needs.

Virtual Network Computing (VNC) is a powerful tool that allows you to connect to and control a remote desktop environment over the network. In this guide, we will walk through the process of setting up a VNC server on Ubuntu Linux, including installing a desktop environment, configuring the default session, and accessing it with a VNC client.

VNC (Virtual Network Computing) is a powerful tool that allows you to remotely access and control a computer’s desktop environment. This can be incredibly useful for managing servers, providing technical support, or simply accessing your system from a different location.

When working with shell scripts in Linux, understanding the appropriate file extension is crucial for efficient development and maintainability. One commonly asked question by new Linux users is, “What is the file extension of a shell script?” This article will answer that and cover all aspects of the bash file extension. You will also learn the different naming conventions, best practices, and how to make your bash script executable.

The bash sh command is a fundamental element in the world of Linux. Many new users and even some experienced ones often find themselves confused about the difference between bash and sh. While they are both command interpreters used to execute commands on Linux, they each have their unique features and use cases.

In Bash scripting, conditional statements like “if” allow you to execute code based on a given condition. However, there are often cases where you need to check multiple conditions at once, and this is where the AND operator comes in handy. Understanding how to use the AND operator in Bash can make your scripts more powerful and efficient.

Choosing the best Linux distro can be a daunting task with the sheer variety of options available. Whether you’re a beginner looking for the best Linux desktop distro, an intermediate user wanting more control, or a power user seeking the best Linux flavor, there is something for everyone in the Linux world.

YUM (Yellowdog Updater Modified) is a package management tool used in Linux distributions like Red Hat, CentOS, and Fedora to manage software installations, updates, and removals. Understanding where YUM installs packages and how to configure or control its behavior can help you manage your system’s software more effectively.

To open a port on Ubuntu, you’ll need to configure the default firewall, UFW (Uncomplicated Firewall). By default, UFW blocks all incoming connections. To allow traffic through a specific port, you must create a new firewall rule. This guide will help you understand how to open a port on Ubuntu using UFW, whether you’re allowing access for a specific IP address, network range, or general traffic.

Configuring a static IP address temporarily on a Linux system is a useful skill, especially for troubleshooting networking issues or for specific network setups where you don’t want to modify permanent settings. A temporary static IP can be assigned to the network interface, which will be active only until the system is rebooted.

Arch Linux and Ubuntu are two extremely popular Linux distributions. While they naturally have a lot of functional overlap, their core principles, user friendliness, and native features are very different. Ubuntu is easy to use, while Arch Linux is more customizable. Rather than trying to decide between the two, it is possible to configure a dual boot system so that you can boot into whichever operating system you feel like using.

Bash scripting is a powerful tool for automating tasks on Linux systems. However, unlike high-level programming languages, Bash doesn’t have built-in try-catch blocks for error handling. Instead, you must implement different strategies to detect and manage errors during script execution. In this article, we will explore five methods for handling errors in Bash scripts, ranging from beginner-friendly to more advanced approaches.

Arch Linux is a robust operating system often chosen by power users and IT professionals. While there is no doubt that it is an extremely powerful OS, the need to use other systems can also arise for users that are required to use a variety of applications and ecosystems that Arch Linux can’t always easily accommodate. This is when a dual boot system that runs both Arch Linux and Windows 11 proves useful.

If you ever get bored of your ordinary, default Ubuntu desktop or you feel that you do not utilize your video card the way you should, you could enable the 3D cube effect to give your desktop an extra spark. This effect is provided by Wayfire, a 3D compositor for Wayland.

Stratis is a free and open source storage management system developed by Red Hat. Available as a technology preview since RHEL 8, it gained full support starting from version 9.3 of the distribution, and can be used also on Fedora. Stratis relies on existing storage technologies such as LUKS, device mapper, and the XFS filesystem, to provide features similar to those integrated in the BTRFS and ZFS filesystems.

Ubuntu is one of the most popular Linux distributions, well known for its ease of use and wide range of available software. In some cases, software comes in the form of .deb packages that need to be installed on your system. When faced with multiple .deb packages, especially when they have dependencies, installing them one by one can be time-consuming.

Vim is a powerful, highly configurable text editor used primarily in Linux, macOS, and other Unix-based systems. Despite its widespread use, one of the most infamous challenges, especially for beginners, is figuring out how to exit Vim after editing a file. Unlike more modern text editors, Vim relies on keyboard commands rather than menus or buttons, which can be a hurdle for those unfamiliar with it.

A snapshot is an image of a filesystem state at a specific point in time. Snapshots are really useful to “turn back time” and bring the system to a known good state if something goes wrong. At the time of writing, there are two main native ways we can create atomic snapshots on Linux: by using LVM (Logical Volume Manager) or by creating a BTRFS filesystem, which has snapshots as a built-in feature.

When working with the Linux command line, the .bash_history file plays a vital role by storing the commands you have executed. By default, the commands are stored only when you exit your terminal session, meaning they might not be saved in real-time. However, it can be beneficial to ensure that all commands are saved to the .bash_history file immediately after execution.

SNMP (Simple Network Management Protocol) is widely used for network management and monitoring. Installing SNMP on RHEL/CentOS systems allows you to monitor various system statistics, interfaces, and other crucial metrics. This guide will walk you through the detailed steps to install, configure, and test SNMP on your RHEL/CentOS system.
