User management is an important part of Linux administration, so it's essential to know about all the user accounts on a Linux system. Some common user administration tasks are to list users, disable a user account, or create and modify user accounts.

Setting up the wireless interface on Ubuntu Linux is likely one of the first things you'll need to do after installing the operating system and booting into it for the first time. As long as you have the proper hardware, Ubuntu can easily connect to Wi-Fi networks configured with various types of security like WEP, WPA, and WPA2.

FTP and SFTP are great protocols for downloading files from a remote or local server, or uploading files onto the server. FTP will suffice for some situations, but for connections over the internet, SFTP is recommended. In other words, FTP is not secure to use over an internet connection, since your credentials and data are transmitted without encryption. The 'S' in SFTP stands for 'Secure' and tunnels the FTP protocol through SSH, providing the encryption needed to establish a secure connection.

One of the best ways to protect your files on a Linux system is to enable hard disk encryption. It's possible to encrypt an entire hard drive or partition, which will keep every file that resides there safe. Without the correct decryption key, prying eyes will only be able to see cryptic gibberish when they try to read your files.

Gnu Privacy Guard (gpg) is the Gnu project free and open source implementation of the OpenGPG standard. The gpg encryption system is called “asymmetric” and it is based on public key encryption: we encrypt a document with the public key of a recipient which will be the only one able to decrypt it, since it owns the private key associated with it. In this tutorial we will see how to generate and create a backup of a gpg keypair.

Rpm is the acronym of RPM Package Manager: it is the low-level package manager in use in all the Red Hat family of distributions, such as Fedora and Red Hat Enterprise Linux. An rpm package is a package containing software that is meant to be installed using this package management system, and rpm packages are usually distributed via software repositories. In this tutorial we learn how to create a custom rpm repository and how to configure our distribution to use it as a software source.

Syncthing is defined as a continuous file synchronization program: it can be used to keep files and directories synchronized across different devices or “nodes”. The application uses TLS as encryption method, and it is, together with its protocol, free and open source software.

In this tutorial we will see how to interact with the Woocommerce API using the Python programming language, showing how to list, create, update and delete products and categories.

When you develop complex Bash scripts and start putting various scripts into a folder, where one script interacts with another by, for example, starting it, it quickly becomes necessary to ensure we know the path the script was started from, so we can start the other scripts with a fully qualified pathname.

RAID 1 is a hard disk configuration where the contents from one hard disk are mirrored onto another. This provides the user with some redundancy in case a disk fails.

The xargs Linux command allows a user to execute command lines from standard input. If that sounds confusing, it might be easier to look at a basic example. The following command would use xargs to cat all the files listed by the ls command.

Running commands or processes in the background on a Linux system becomes a common task if you need to free up your terminal or disconnect from an SSH session. This is especially true of commands that run for a long time, either to listen for events or complete their lengthy task.

Concrete5 is a CMS (content management system) which allows users to edit any page via editing toolbar and change its content or design without reading complicated manuals or navigating a complex administration back-end.

The objective is to install the NVIDIA drivers on Ubuntu 21.04 Hirsute Hippo Linux and switch from a opensource Nouveau driver to the proprietary Nvidia driver.

Logical Volume Manager (LVM) is used on Linux to manage hard drives and other storage devices. As the name implies, it can sort raw storage into logical volumes, making it easy to configure and use.

Docker is a tool that is used to run software in a container. It's a great way for developers and users to worry less about compatibility with an operating system and dependencies because the contained software should run identically on any system.

It is not much fun when your Desktop hangs. The fear of lost work, the inability to continue work, and more. But it need not always be like this. Knowing just a little extra - a few shortcut keyboard combinations and a few commands at the command line - will hopefully get you back up and running quickly. It does not always work, but it works often.

LUKS (Linux Unified Key Setup) is the de-facto standard encryption method used on Linux-based systems. While the Debian installer is perfectly capable of creating a LUKS container, it lacks the ability to recognize and therefore re-use an already existing one. In this article we see how we can workaround this problem using the “DVD1” installer, and running it in “advanced” mode.

The release of AlmaLinux in 2021 was spurred by the change of CentOS Linux from an enterprise-stable operating system to an upstream development branch of RHEL. With AlmaLinux being branded as a replacement for CentOS, and giving users the option to migrate to AlmaLinux from CentOS, you may be wondering what the differences are between these operating systems.

Bash is a great coding language, which allows you to do complex things like Big Data Manipulation, or simply create sever or desktop management scripts. The entry level skill required to use the Bash language is quite low, and one-liner scripts (an often used jargon, which indicates multiple commands executed at the command line, forming a mini-script), as well as regular scripts, can grow in complexity (and how well written they are) as the Bash developer learns more.
