• How to Install KVM on RHEL 9 Step-by-Step

  In this guide, we will cover how to install KVM on RHEL 9 step-by-step.

  Kernel-based Virtual Machine, or KVM in short, is an opensource virtualization solution for the Linux kernel. It supports both Intel and AMD CPUs and allows users to create and manage virtual machines on a Linux system. The kernel functions as a hypervisor and allows you to virtualize your entire dedicated server and create multiple VMs.

• DNS settings to avoid email spoofing and phishing for unused domain

  As you may know, email spoofing allows attackers to pose as someone else to gain illegal profit. For example, I only use webmaster@cyberciti.biz for communication, but someone might create a spoofed-up email, say info@opensourceflare.com, to trick someone.

• How to set filesystems mount order on modern Linux distributions

  In a previous tutorial we discussed about the /etc/fstab file, and how it is used to declare the filesystems which should be mounted on boot. In the pre-Systemd era, filesystem where mounted in the order specified in the /etc/fstab file; on modern Linux distributions, instead, for a faster boot, filesystem are mounted in parallel. Systemd manages the mounting of filesystems via specifically designed units automatically generated from /etc/fstab entries. For these reasons a different strategy must be adopted to establish the dependency between two filesystems, and therefore to set their correct mount order.

  In this tutorial we see how to establish an explicit dependency between two filesystems and set their mount order on modern Linux distributions.

• How to install Gacha Club Edition Beta on a Chromebook

  Today we are looking at how to install Gacha Club Edition Beta on a Chromebook. Please follow the video/audio guide as a tutorial where we explain the process step by step and use the commands below.

• How To Use I/O redirections in Linux - ByteXD

  In this article you will be acquainted with the concept of I/O redirections, and the different ways to use standard output, standard input and standard error.

• How to install Java 11 in OpenSUSE in Rocky Linux/Alma Linux 9

  In this guide we are going to explore how to install Java Runtime Environment (JRE) and the Java Developer Kit (JDK) in Rocky Linux 9. This guide also works for RHEL 9/Alma Linux 9.

  Java and the JVM (Java’s virtual machine) are required for many kinds of software, including Tomcat, Jetty, Glassfish, Cassandra and Jenkins.

  Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. Java was developed by Sun Microsystems (which is now the subsidiary of Oracle) in the year 1995. James Gosling is known as the father of Java.

• How to install and set up Jenkins in Rocky Linux/Alma Linux 9

  In this Guide we are going to learn how to install and configure Jenkins in Rocky Linux 9. This will also work for other RHEL 9 derivatives like Alma Linux.

  Jenkins is a popular opensource automation tool to perform continuous integration and build automation. Jenkins allows to execute a predefined list of steps, e.g. to compile golang source code to build build binary file. The trigger for this execution can be time or event based.

• How to disable Plymouth on Linux

  Plymouth is an application originally developed by Red Hat and later adopted basically by all the most commonly used Linux distributions. The software runs very early in the boot process, and provides eye-candy animations which accompany the user until he is prompted to login into the system. When Plymouth is used, boot messages are hidden, although they can be visualized simply by clicking the esc key. Some users, however, may prefer to visualize boot messages by default, and avoid any animation.

  In this article we see how disable Plymouth animations on some of the most used Linux distributions.

• How to customize the SDDM display manager on Linux

  SDDM (Simple Desktop Display Manager) is a modern, free and open source Display Manager available on Linux and other Unix platforms like FreeBSD. It works both with X11 and Wayland, and is based on QtQuick, a framework to build QML applications. SDDM allows a great degree of customization and; thanks to this, a lot of custom themes are available for it.

  In this tutorial we see how to install and enable SDDM on some of the most used Linux distributions, and how to change its look by using custom themes.

• How to create snapshots of QEMU/KVM guests

  KVM (Kernel-based Virtual Machine) is the virtualization solution (type 1 hypervisor) included in the Linux kernel, which, by default, is used together with QEMU, the userspace software which actually performs the guest systems emulation (type 2 hypervisor). In a previous tutorial we saw how to create and manage KVM virtual machines from the command line; in this article, instead, we will learn how to create and manage guest systems snapshots using tools like virsh and virt-manager.

  In this tutorial we learn how to create snapshots of guest systems emulated with QEMU/KVM, using virsh and virt-manager.

• How to create a Linux virtual machine with VirtualBox | ZDNet

  Linux is everywhere -- in phones, smart appliances, cloud storage services, cars, thermostats, and just about everything with an embedded system or a major third-party service.

  It can also be on your desktop. Linux is a fantastic choice as a desktop operating system because it's incredibly reliable, secure, and more flexible than any other OS on the market. But for those who might be hesitant to install Linux over macOS or Windows, what can you do? One route that makes it very easy to test and use Linux, without doing anything to your primary operating system, is the virtual machine route.

• Installing SurfShark VPN On Kali Linux: The Authoritative Guide

  Virtual Private Networks (VPNs) were initially created to grant workers who are remote, workers who travel, or workers who do not tend to be in the office access to the local network over an insecure network connection when they are not physically within the local network. Essentially, a VPN can be used for various reasons however, the main purpose was for the use of businesses and companies. Not only would workers need to access resources on the company network but companies with multiple offices that need to work in unison as if they’re on the same network found that a VPN would be the ultimate solution. Nowadays, daily computer users use VPNs for many different use cases but mainly, they want to maintain their privacy and better control access to resources. VPNs are used to guard daily users and companies alike against cyber criminals on public networks and are also used for hiding your IP address, your browsing activity, and your personal data on any network you may be connected to, whether it be at home or at a coffee shop. Ultimately, what mostly all VPNs have in common is the ability to connect remotely to a private network over a public connection. VPNs are used to secure internet connections, protect against malware and hacking, maintain digital privacy, gain access to geo-restricted content, and conceal users' physical locations. A VPN is an essential tool for staying safe and secure online as more and more users value their privacy, as well as companies with multiple offices and remote workers.

• Keychron keyboards fixed on Linux | Bastian Venthur's Blog

  Last year, I wrote about on how to get my buggy Keychron C1 keyboard working properly on Linux by setting a kernel module parameter. Afterwards, I contacted Hans de Goede since he was the last one that contributed a major patch to the relevant kernel module. After some debugging, it turned out that the Keychron keyboards are indeed misbehaving when set to Windows mode. Almost a year later, Bryan Cain provided a patch fixing the behavior, which has now been merged to the Linux kernel in 5.19.
