(more…)LearnLinuxTV’s Proxmox full course aims to get you up to speed with all the finer points of Proxmox Virtual Environment. In video #12, we take a look at the Command-Line interface. The basics of both the qm and pct commands are covered, so by the end of the video you’ll be able to manage your cluster with or without a user interface.
In this episode of Linux Essentials, we’ll take a look at how to send tasks to the background, and then bring them to the foreground. This helps you get the current task out of the way so you can switch to something else, without having to use multiple terminal windows.

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.
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.
The process of launching a Windows virtual machine on Proxmox is a bit more involved when compared to launching a Linux VM, but in this video, I’ll go over the entire process to make it easy. Follow along with me, and you’ll have your own Windows VM running on Proxmox. This method covers both Windows 10 and Windows Server.
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.
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.
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.
CrowdSec is a solution that aims to help protect your Linux servers, and its approach is quite different than other solutions. CrowdSec is able to utilize reputation to make intelligent decisions, and is able to be extended to meet your needs. In this video, I take a first look at CrowdSec – I’ll show you the installation process and also an example scenario so you can see it in action.
