Lynis is a free and open-source security auditing tool released as a GPL licensed project and is available for Linux and Unix-based Operating systems. In this tutorial, we will provide instructions on how to perform a Lynis security audit on a remote system.

VIA announced a “VIA SOM-9X35 Starter Kit” that runs Linux or Android on an NPU-equipped, 2GHz, quad -A53 MediaTek i350 via a VIA SOM-9X35 module with 2GB LPDDR4 and 16GB eMMC. The kit includes a 7-inch touchscreen and 13MP camera.

In this article, we will see what a Terraform state is and how to manage it on an S3 Bucket.  We will also see what "lock" is in Terraform and how to implement it. To implement this, we need to create an S3 Bucket and a DynamoDB Table on AWS.

One of the things that open source prides itself on is choice. You don't have to settle for anything you don't love. You can change your file manager, your text editor, and you even have over 24 desktops to choose from. As with many Linux users, I was pretty flexible about the desktop I used at first. I didn't know what I liked at first, because I hadn't tried everything available to me.

Knowing how much space a file or folder consumes on a partition is essential for a system administrator or developer. This knowledge allows you to plan for storage upgrades, manage and rotate files, and do other necessary sysadmin tasks. My favorite command for this type of data gathering is the du command.

Whether you're interested in them as part of your job, for future job opportunities, or just out of interest in new technology, containers can seem pretty overwhelming to even an experienced systems administrator. So how do you actually get started with containers? And what's the path from containers to Kubernetes? Also, why is there a path from one to the other at all? As you might expect, the best place to start is the beginning.

Whether we’re using a Raspberry Pi or a data center server, we need to know how our CPU and RAM are performing and, in Linux, there are a plethora of commands and applications that we can use. At the basic low level “How much RAM have I used?” to inspecting the CPU for vulnerabilities such as Spectre, there are commands at our disposal.

Bring your old PC back to life by installing Tiny Core Linux, the smallest and the most lightweight Linux distro you can get your hands on.

I used to marvel at people who required more than one clock, each set to an exotic timezone, on the wall. I saw it mostly in movies, so when I met someone in real life with lots of clocks, it made them seem particularly important, like the leader of a global spy network or a big banking syndicate. And yet lately, I find myself needing to be aware of at least three different timezones on a regular basis. It's not that I've become more important, it's just that the world has gotten smaller, thanks to technology and remote work.

Want to get a macOS-like dock on your Linux desktop? These seven dock apps will help you recreate the Mac desktop experience on Linux.

A good photo can be a powerful thing. It expresses what you saw in a very literal sense, but it also speaks to what you experienced. Little things say a lot: the angle you choose when taking the photo, how large something looms in the frame, and by contrast the absence of those conscious choices.

Almost exactly a year after we last covered it, an experimental version of LibreOffice compiled to WebAssembly (nicknamed LOWA) has appeared. Be warned, it's about 300MB, so it takes a while to load, but you can try it here in your browser.

I decided to run Kanboard, an open source project management application, in a rootless Podman pod as a small weekend project. The pod consists of three containers, an infra-container, a kanboard-container, and a postgresql-container. That deployment went well, but eventually, the image I used for the postgresql-container became deprecated, meaning it was no longer receiving updates. It was time to move to a different image, but that meant migrating a database between containers.

When you want to try a new app on your phone, you open your app store and install the app. It's simple, quick, and efficient. In this model of providing applications, phone vendors ensure that you know exactly where to go to get an app, and that developers with apps to distribute know where to put their apps so people can find them.

The GNOME Project has announced that it's retiring the Clutter library, the tool that bought OpenGL-based hardware rendering to Linux in 2006. Clutter was originally written by now-Intel subsidiary OpenedHand and in its day was a widely used library, enabling GObject-based C code to draw user interfaces using OpenGL.

OSS-Fuzz is a free service that continuously runs fuzzers for open source projects. This GitHub repository manages the service and enrolling in it is handled by pull requests. Once a project has integrated with OSS-Fuzz, the fuzzers affiliated with that project run daily—continuously and indefinitely. OSS-Fuzz emails maintainers when a bug is found and also has a dashboard with details about all issues found (stack traces, artifacts for reproducing issues, and so on).

Are you using Fedora Silverblue or Fedora Kinoite and looking for some ideas about what you can try out on your system? This article might inspire you and help get you started.

Grafana is a free and open-source data visualizing tool that is used to monitor metrics from other hosts. In this post, we will show you how to install Grafana 8 on Debian 11.

Nebulon has integrated its smartInfrastructure platform with Red Hat's Ansible software – including a set of modules that allow users to automate Nebulon infrastructure deployment and management by using Ansible Playbooks.

SSHFS (SSH File System) is an implementation of a File System in User Space (FUSE) that enables clients to mount remote filesystem over SSH connection. In this tutorial, you will learn how to mount a remote directory in a secure way using the SSHFS between two Linux machines (client and server). This guide also includes how to set up chroot on SSHFS that will prevent users from accessing other users' directories.
