What Linux distributions, hardware, and software do I actually use? In this video, I share some of the Linux distros, laptops, desktops, server operating systems, and applications that currently support my workflow.
You’ll learn which Linux distributions I’ve been using lately, why keeping an alternative distro in mind can be useful, and which distro I prefer for Linux servers. I’ll also show you some of my current computer hardware and briefly discuss several Linux apps and tools I use.
If you’ve ever rebooted a Linux server and had it fail to come back up, there’s a good chance the culprit is sitting right in your /etc/fstab file. Device names like /dev/sda1 can shift after a reboot, a drive swap, or even a kernel update — and when that happens, your mounts break and your server may not boot at all. In this video, I break down why UUIDs matter for Linux storage, and I show you a real production server that ran into exactly this problem.
In this video, I’ll walk you through the essential first steps you should take every time you deploy a new Linux server. Whether you’re a seasoned sysadmin or just getting started with Linux server administration, these foundational steps will help you secure your server, set up SSH key authentication, and establish a solid baseline configuration.
Is Linux uptime really something to brag about? Many system administrators proudly show off servers that haven’t been rebooted in months or even years—but that mindset can actually create serious problems!
In this video, I’ll break down why you might be revealing more than you intended to, and why rebooting your Linux server regularly can actually be a best practice. From applying security updates to maintaining system reliability, avoiding reboots can introduce risks that many sysadmins overlook.
In this video for new Linux users, Jay covers the essential first tweaks that should made to every new Linux server build. Although these first tweaks may seem a bit “basic”, don’t underestimate their importance! A little preparation goes a long way.
With the Linux Crash Course series, we’ll go over one important Linux-related topic – one video at a time. This time around, here’s a video for those of you that are brand-new to Linux that will cover how to connect to a Linux server via the OpenSSH client.
Were you every confused regarding the differences and use-cases between a hostname and domain name for a device within your network? How does naming your servers benefit you? In this latest episode of the Linux Crash Course series, we’ll explore some foundational concepts around both.
CrowdSec is an Intrusion Prevention System that does things a bit differently than other IPS solutions. It’s collaborative, and open-source. CrowdSec has been featured on LearnLinuxTV a few times in the past, but in this video we’ll explore the CrowdSec Console, which allows you to monitor the security events of your Linux servers from an impressive web dashboard. In this video, we’ll get an overview and see it in action!
Note: This is not a review, but an overview of a security solution that Learn Linux TV is actually using in real-life.
Gitea is a self-hosted git server you can run on your Linux rig, enabling you to be in full control of hosting your own repositories. In this video, the process of setting up Gitea is shown on an AlmaLinux server. You’ll see the process of setting up the server, installing Gitea, and even making your first commit to a repository that’s being hosted on your new server.
