XFS is a journaled filesystem originally developed by Silicon Graphics in 1993; it was released under the GPL license in the year 2000 and ported to the Linux kernel in 2001. Due to its high scalability and performances, XFS became the default filesystem in recent versions of Red Hat Enterprise Linux and its clones.
This tutorial will deal with Ubuntu static IP address configuration. It will provide the reader with a step by step procedure how to set static IP address on Ubuntu Server via netplan and Ubuntu Desktop using NetworkManager. Static IP address is recommended for servers as the static address does not change as oppose to a dynamic IP address assignment via DHCP server.
Until recently, Kali Linux used the root account by default and now you need to set Kali root password manually. In the latest versions of Kali, root login is disabled, forcing you to login to the GUI as your normal user account. The reasoning behind this change should be obvious, but if you’re a Kali user, you probably know your way around a Linux system by now, and there’s not much risk in letting you use the root account to login.
The Vim editor (and its predecessor, vi) is a command line editor for Linux systems. It has a long standing reputation as being the most powerful text editor on Linux. After mastering it, many users will even claim that it is far speedier and more convenient to use than a typical GUI editor packed with lots of features in its menus.
Virtualization is a helpful technology that has exploded in popularity and accessibility in the last decade. There are many great reasons to use virtual machines, such as having a test environment separate from your host operating system. It also allows you to run multiple operating systems or Linux distros simultaneously – all inside of their own sandboxed environment, with optional network interconnectivity among your machines.
Users have a lot of choices when it comes to virtualization on a Linux system. There are many use cases for virtualization, whether you want to have a test system that is isolated from your host system, test out a different Linux distribution, or even run a completely different operating system. Whatever the case may be, you will need to have a hypervisor. A hypervisor is what manages and allows you to interact with your virtual machines.
VNC is a system that allows you to remotely control another computer. It allows you to relay your mouse and keyboard inputs as if you were physically sitting in front of the system, when in fact you could be on the other side of the world. It works well for sharing your desktop screen with another user, whether you want to grant them the ability to control your computer or just be able to see what you are doing on it (with mouse and keyboard input blocked).
By default, the Fedora Linux distribution sports the GNOME desktop environment, although others are available in “Spin” downloads. If you would like to change things up and install KDE Plasma instead, the GUI can be downloaded and installed directly from Fedora’s default package repositories.
One of the best aspects of using a Linux system is that there are many popular desktop environments to choose from. If you do not like the style or behavior of yours, it is simple enough to install a different one. When it comes to the KDE Plasma desktop environment, there are a few different ways to experience it.
Obtaining the load average of your server(s) will shed some light on the system’s CPU usage over time. As a Linux system administrator, it is essential to obtain the load average occasionally, as to determine whether or not your systems are overwhelmed by trying to handle the current work load. Because of the way load averages are reported, it is also easy to determine if the server is being overloaded, which may mean it is time to divide up the work load across load balancing servers, or upgrade your current hardware.
Column is a free and open source utility usually installed as part of the util-linux package in all the most common Linux distribution, and therefore included in even the most minimal installations. With this utility we can organize the content of files or the output of other commands in columns, creating pretty tables or even producing JSON formatted documents.
