In this article you will learn about some Ubuntu 22.04 features of the upcoming Ubuntu stable release. Canonical’s latest iteration to the Ubuntu operating system is Ubuntu 22.04 Jammy Jellyfish, scheduled for release on April 21, 2022. This is an LTS (long term support) release – the type of release that Canonical only publishes every two years, and continues to support for the next five.

Wake-on-lan (also known with the “W.O.L” acronym) is a standard ethernet feature which allows a machine to be woken up on the reception of a specific type of network packet (the so called MagicPacket). The main advantage of this feature is that it allows us to keep a machine in a low power consumption state, and be accessed only when needed. In this tutorial we see how to enable the WOL feature on our ethernet card under Linux, and how to send the network packet needed to wake up a machine.

As a response to the recent changes in CentOS strategy, CloudLinux announced a 1:1 binary compatible, community-driven fork of RHEL called Project Lenix. Can you tell us more about the motivation behind this project?

Kodi's support for DRM in version 18 and beyond opened the doors to streaming services like Sling TV. It's simple enough to get it running within Kodi and start watching live TV legally.

Using a combination of the youtube-dl script and FFMPEG, you can easily rip audio from YouTube videos and instantly convert it to MP3, OGG, or any other audio format that you prefer for your music library.

As time passes, it appears that corporations are primarily considering one distribution when considering installing Linux, and that distro is clearly RedHat. That probably does not come as any major surprise, but it appears RedHat's dominance continues to get stronger. What use to be a landscape littered with a multitude of choices has nearly been rendered down to one. Wow! That didn't take long. The open source software dynamic seemed to be formed on the premise that users were never again going to be pigeon-holed into using one piece of software. Or, perhaps better stated, that was a byproduct of making the source code readily available. And, that is still true to this day. However, as a corporate citizen in today's business climate, one finds themselves with limited possibilities.

In the past, multimedia was a sore point for Linux users. Now, though, it's a strength. There are plenty of fantastic DVD and video players for Linux systems, including Ubuntu. As an added bonus, they all should be readily available in the default Ubuntu repositories.

Rsync is a very useful tool which allows Linux system administrators synchronize data locally or with a remote filesystem via the ssh protocol or by using the rsync daemon. Using rsync is more convenient than simply copying data, because it is able to spot and synchronize only the differences between a source and a destination. The program has options to preserve standard and extended filesystem permissions, compress the data during transfers and more. We will see the most used ones in this guide.

The objective is to install the NVIDIA drivers on Ubuntu 19.10 Eoan Ermine Linux. Perform an automatic Nvidia driver installation using standard Ubuntu Repository, PPA repository or manually using driver from nvidia.com.

When we delete a file from a filesystem, the data is not physically removed: the operating system simply marks the area previously occupied by the file, as free and makes it available to store new information. The only way to make sure data is actually removed from a device is to override it with other data. We may want to perform such operation for privacy reasons (maybe we plan to sell the device and we want to be sure the new owner cannot access our data), or maybe to prepare a device for encryption. In this tutorial we will see some tools we can use to completely wipe data on a device.

Red Hat has built its own tools, buildah and podman, which aim to be compatible with existing docker images and work without relying on a daemon, allowing the creation of containers as normal users, without the need of special permissions (with some limitations: e.g. at the moment of writing, it's still not possible to map host ports to the container without privileges).

The dropbear suite provides both an ssh server and a client application (dbclient), and represents a light alternative to OpenSSH. Since it has a small footprint and uses system resources very well, it is generally used on embed devices, with limited memory and processing power (e.g routers or embed devices), where optimization is a key factor. It provides a lot features, like, for example, X11 forwarding, and it is fully compatible with the OpenSSH public key authentication. In this tutorial we will see how to install it and configure it on Linux.

The NVIDIA Driver is a program needed for your NVIDIA Graphics GPU to function with better performance. It communicates between your Linux operating system, in this case CentOS 8, and your hardware, the NVIDIA Graphics GPU. The NVIDIA drivers can be installed by using the bash command after stopping the GUI and disabling the nouveau driver by modifying the GRUB boot menu.

In this article we will talk about foremost, a very useful open source forensic utility which is able to recover deleted files using the technique called data carving. The utility was originally developed by the United States Air Force Office of Special Investigations, and is able to recover several file types (support for specific file types can be added by the user, via the configuration file). The program can also work on partition images produced by dd or similar tools.

There are a few ways to convert video files on Linux. If you're a fan of command line tools, check out our FFMPEG video conversion guide. This guide is going to focus on HandBrake, a powerful graphical video conversion tool to covert video from and to many formats such as MP4, AVI, WebM and many more.

There has been concern for nearly five years application servers are dead. Truth be told, they are not dead, but is their usage in decline? The simple answer is yes. Over the years, it appears corporate environments have decided the return on investment is not there when looking at Java application servers. On the surface, one might assume that the likes of WebSphere or WebLogic might be the ones in decline due to cost.

Nrpe, or Nagios Remote Plugin Executor, is the client side service of a monitoring setup. The monitoring server will send commands to the client, which listens passively when got no work to do. Upon incoming command, the nrpe checks it's local configuration, and executes the plugin configured with the command, then sends back the results to the server for processing. You can read more about the server side installation in the Nagios installation guide, while this guide will focus on the client side.

FLOSS is penetrating the government sector of countries throughout the world. That holds true right here in the good ole U.S.A. A world that was intent on utilizing proprietary software is slowly changing its tune. The United States has not been as progressive in this area as some other countries, but over the course of the last few years, it has finally decided to jump on the train. The benefits are just too hard to ignore. While this topic is wide ranging, the focus of this piece will be on the Department of Defense (DoD) in particular.

MySQL workbench is a graphical application which let us manage data and perform administrative tasks on MySQL databases. In this tutorial we will see how to install the program on Ubuntu 18.04 (Bionic Beaver) and we will perform a brief tour of some of its most basic functionalities to make your Linux system administration job easier.

The Openssh set of utilities let us create secure, encrypted connections between machines. In this tutorial we will take a look at some of the most useful options we can use to change the behavior of sshd, the Openssh daemon in order to make your Linux system administration job easier. In this article we assume the existence of an already running and accessible server. If you want to know more about OpenSSH installation, you can take a look at this article on how to install SSH server on Ubuntu Linux.
