• How to partition USB drive in Linux

  In order to access a USB drive on Linux, it needs to have one or more partitions on it. Since USB drives are usually relatively small, and only used for temporary storage or to easily transfer files, the vast majority of users will choose to configure just one partition that spans the entire USB disk. However, you can also logically separate the USB drive into different sections if you wanted to use multiple partitions.

  In this tutorial, we will cover the step by step instructions to partition a USB drive on a Linux system. You will also learn how to create new partitions, delete partitions, and to shrink or expand existing partitions on the USB drive. You will see the steps for both command line and GUI methods, so you can follow along with set of instructions you are most comfortable with. Let’s get started.

• How To Change Hostname on Rocky Linux 9 - idroot

  In this tutorial, we will show you how to change the hostname on Rocky Linux 9. For those of you who didn’t know, In the Linux operating system, the hostname is a name that is assigned to a device (such as a computer or server) that is connected to a network. The hostname is used to identify the device on the network and is usually a combination of letters and numbers. In this case, we can assign a unique hostname to each machine to remember them easily. Hostname also allows each machine to communicate using the device name rather than the IP address.

  This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step change of hostname on Rocky Linux. 9.

• How to Install Linux Kernel 6.1 on AlmaLinux EL9 or EL8

  On December 11, 2022, Linux Kernel 6.1 was released with a significant new addition – initial Rust language support in mainline Kernel. This release has been highly anticipated by users who seek to increase security and memory-safe code. While performance enhancements are typically in a Linux Kernel release, this may be especially desired for users with new hardware that is unsupported or has issues in their current Linux distribution Linux kernel.

  Specific Linux distribution, such as AlmaLinux, is known for providing long-term stability. However, the latest Kernel requires installation from a third-party source such as ELRepo unless you are comfortable compiling it yourself. For most users, dealing with the frequent release of minor updates that can occur almost weekly using a well-known repository that supports the latest Linux Kernels, such as ELRepo, comes in handy and is recommended.

  As discussed in the introduction, the best option is to use the ELRepo repository, which has an excellent reputation amongst EL9 and EL8 distributions such as CentOS, Oracle, Rocky Linux, etc. The following tutorial will show you how to import the ELRepo for AlmaLinux 9 or AlmaLinux 8 desktop or server using cli commands for the users that require to update their Kernel for better hardware support.

• How to install Ubuntu on USB Stick

  Installing Ubuntu Linux onto a USB stick will allow you to have a portable operating sysem that you can plug into any computer. This differs from a live environment USB, as installing Ubuntu directly to a USB stick will create a persistent operating system, the same way it does when you install to a typical hard disk. However, the process of installing Ubuntu to USB is not the same as a usual hard drive.

  There are some differences in the installation process and important caveats to keep in mind if you plan to install Ubuntu to a USB stick. We will go over those in the sections below. In this tutorial, we will cover the step by step instructions to install Ubuntu Linux to a USB flash drive.

• How to Install Vivaldi Browser on Ubuntu 22.10/22.04/20.04

  Vivaldi is a powerful and innovative browser attracting considerable attention among Ubuntu desktop users as a strong contender to replace the default installed Firefox browser. It came about after the developers of Opera decided to switch from their successful Presto engine to the Chromium-based browser; many traditional Opera fans were understandably upset at this transition, which resulted in an upsurge in interest in Vivaldi as an alternative option. Even though it is relatively new, its popularity has proved highly significant, with many computer users now considering it an important competitor against Chrome, Firefox, and Edge. A range of unique tools and features make Vivaldi an excellent choice for those seeking a reliable Internet browsing experience.

  In the following tutorial, you will learn how to install Vivaldi on Ubuntu 22.10 Kinetic Kudu, 22.04 Jammy Jellyfish, and 20.04 Focal Fossa using the command line terminal and also the option of Vivaldi stable or Vivaldi snapshot browser versions.

• Yes! You Can Install Unity Desktop on Arch Linux. Here’s How! - It's FOSS

  Several years after Ubuntu abandoned the Unity desktop environment, a few volunteers put effort to release a new version 7.6. Heck! Their Ubuntu Unity project is now an official Ubuntu flavor.

  If you liked the Unity desktop and want to try it again, you don’t necessarily have to use Ubuntu Unity. Arch Linux users have a way to install it.

• How to Install ModSecurity 3 with Nginx on Fedora 37/36

  ModSecurity, often referred to as Modsec, is a free, open-source web application firewall (WAF). ModSecurity was created as a module for the Apache HTTP Server. However, since its early days, the WAF has grown and now covers an array of HyperText Transfer Protocol request and response filtering capabilities for various platforms such as Microsoft IIS, Nginx, and Apache.

  How the WAF works, the ModSecurity engine is deployed in front of the web application, allowing the engine to scan the incoming and outgoing HTTP connections. ModSecurity is most commonly used in conjunction with the OWASP Core Rule Set (CRS), an open-source set of rules written in ModSecurity’s SecRules language, and is highly regarded in the security industry.

• How to install Docker on AlmaLinux 9 Linux? - Linux Shout

  We have covered the installation steps for setting up Docker packages on Almalinux 9 using the command terminal in this tutorial.

  Almalinux 9 is the latest server Linux distro based on RedHat code. We can easily configure Docker on Almalinux 9 to run container service. Container service is slightly different than our regular VirtualBox or Vmware Desktop Virtualization.

  In Docker, the OS images are lightweight, hence easy to install and consume fewer resources. Further, they run virtual containers at native speed. Many cloud services offer Alamlinux, hence let’s know how to use it for working with Docker Containers.

• OpenLiteSpeed as reverse proxy

  In this tutorial, you will learn how to configure OpenLiteSpeed as a reverse proxy server. A system that sits between a client and a web server (or servers) can be configured as a reverse proxy. The proxy service acts as a frontend and works by handling all incoming client requests and distributing them to the backend web, database, and/or other server(s). The advantages of a reverse proxy become most apparent under high traffic conditions or situations where multiple backend servers are deployed and need some form of load balancing.

  Follow along with us below as we take you through the step by step instructions to configure OpenLiteSpeed as a reverse proxy server on a Linux system. OpenLiteSpeed can act as our central point for incoming connections and provide us with load balancing, central logging, improved security, and better performance. We will set up OpenLiteSpeed as a reverse proxy for our Apache backend in the steps below.

• OpenLiteSpeed htaccess setup

  One of the most alluring features of OpenLiteSpeed is that it is highly compatible with Apache, so web admins migrating from Apache web server to OpenLiteSpeed will not have to spend much time converting their configuration. When using the Apache web server, .htaccess files (also called “distributed configuration files”) are used to specify configuration on a per-directory basis, or more generally to modify the behavior of the Apache web server without having to access virtual hosts files directly (this is usually impossible for example, on shared hosts).

  Although .htaccess files were developed with Apache in mind, OpenLiteSpeed also has the ability to read them. This makes OpenLiteSpeed able to act as a drop in replacement for those wishing to migrate from Apache. In order for OpenLiteSpeed to recognize .htaccess files, the pertinent setting must be enabled. In this tutorial, you will see how to enable htaccess support in OpenLiteSpeed on a Linux system.

• Ubuntu server tutorial for beginners

  Most people probably know of Ubuntu as a desktop operating system. But Ubuntu’s massive popularity and strong footing in the Linux community have allowed Canonical to produce a very viable server edition and still maintain their desktop release. Ubuntu Server is a great choice if you are looking for an operating system for your production servers such as web servers, database servers, file servers, etc. It is free, stable, scalable, and has optional support plans.

  After downloading Ubuntu Server and installing the operating system, there is some initial setup and configuration that administrators should do. In this tutorial, we will guide you through some of the most common tasks that beginners should know about, so you can get your Ubuntu Server up and running smoothly.

• How to make a bootable USB from an ISO in Linux

  The purpose of this tutorial is to make a bootable USB drive from an ISO file. USB drives have recently overtaken CDs and DVDs as the primary media of physically distributed software. It is now a common task for system administrators and normal users to install operating systems and software via USB.

  When you download a Linux distro, chances are that it will come as an ISO file and you will need to burn it to USB in order to install Linux on a computer. This allows you to boot directly into the Linux installer. Similarly, we can also put other software on the USB drive, assuming that the installer is distributed as an ISO file.

  In this tutorial, you will see the step by step instructions to create a bootable USB from an ISO file on a Linux system. We will cover the steps for both command line and GUI on major Linux distros.

• A Tale of "More" and "Less" Commands in Linux

  Linux users often use “more” and “less” commands interchangeably to read large files without understanding their differences, as their definitions are also identical in the manual.

  So, what’s their difference, and when should you use them? All of this doubt will be cleared in this article, including how to effectively use them with practical examples.

  But first, let’s start with their definition:

  The more command is used to read large files by displaying one page at a time and scrolling up and down through pages; you can even pipe it with other commands like cat.

• Search for packages in Ubuntu using the apt search

  To install a package, knowing the exact name of the package is necessary.

  Such as to install apache in Ubuntu, you can not use sudo apt install apache. You will have to specify the apache2 instead of plain apache.

  And I have encountered many errors like this and that's why I came up with this guide so you don't have to.
