We’ve talked about Enterprise Linux Security from the worldview of the system administrator, but what’s it like on the other side? In this episode, Jay and Joao are joined by Atalay Kelestemur, an Ethical Hacker, as we discuss the mindset of the attacker.
Aliases in Bash enable you to essentially create your own commands, or even just simplify existing ones. In this video, I’ll explain what aliases are, and I’ll show you some of my personal favorites. At the end, I’ll show you how to make your aliases persist between sessions.
LearnLinuxTV’s Proxmox full course aims to get you up to speed with all the finer points of Proxmox Virtual Environment. That effort continues in the eleventh episode, which goes over the integrated firewall within Proxmox. By the end of this video, you’ll be able to deploy firewall rules within your own Proxmox cluster.

I’m so happy to let you guys know about a very special development with LearnLinuxTV, that it’s going to be my only job going forward. It’s been a lot of hard work to get to this point, but it’s here and I’m very excited! Check out the video for more details on my decision.
Backing up your virtual machines and data is extremely important, yet something that quite a few administrators don’t spend enough time on. In this video, I’ll walk you through the backup and snapshot options that are available within Proxmox.
Flatpaks are a universal package type that gives you cross-distribution access to popular Linux apps. In this video, I’ll show you how to configure Ubuntu for Flatpak support, and we’ll install a few apps. In addition, I’ll show you command-line methods as well.
Welcome back to LearnLinuxTV’s full course on Proxmox Virtual Environment! In class #9, we’ll look at how user management is structured, and we’ll walk through the process of creating several accounts. Also, we’ll take an initial look at groups and permissions as well.
When you write software, there’s no reason to reinvent the wheel – shared libraries and other resources exist to enable you to create applications while avoiding redundant work. Unfortunately, sometimes the software supply itself chain is attacked, which would mean that your application contain malware or security threats you didn’t account for. In this episode of Enterprise Linux Security, Joao and I discuss supply chain attacks, as well as some ways to mitigate this threat.
Universal Linux Apps/Packages (Flatpaks, Snaps, AppImages) seem to get a lot of hate in the Linux community, but why?! In this video, I talk about why this type of technology is not only necessary, but a good thing.
Public Key Authentication with OpenSSH is preferred, as it’s a much stronger method of authenticating to your servers when compared to using password authentication. In fact, password authentication in OpenSSH should always be disabled. But before you can password authentication, you’ll need to set up public key authentication, and that’s exactly what we’ll do in today’s video.
Welcome back to LearnLinuxTV’s full course on Proxmox Virtual Environment! In class #8, we look at the process of converting a container into a template, that can then be used as a basis for launching additional containers.
As Linux server administrators, we need to be able to schedule tasks to run at some point in the future. Perhaps as a one-off command, or a job that’s expected to repeat on some sort of schedule. And that’s exactly what Cron helps us to do – by setting up a Crontab, we can schedule tasks to run at some point in the future.
