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.
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.
Migrating your servers from one Linux distribution to another can be a daunting task, even moreso if it’s a migration you’re doing because of unforeseen events or changes within the ecosystem. In this video, Jay and Joao discuss the challenges when it comes to migrating Linux distributions, and the effect this has on security.
Rebooting is a pain, and in some organizations, downright tedious. Shuffling virtual machines between hosts in a cluster is even more tedious, and when it’s time to install patches, that’s what many administrators are forced to do. In this video, I check out QEMUCare, which aims to live-patch QEMU to avoid VM shuffling. In particular, we’ll look at installing ePortal (which deploys the patches) and also an example scenario.
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.
Crunchbang++ 11 was recently released, and it’s awesome! So, why aren’t more people aware of this really good Linux distro? Crunchbang++ is lightweight, fun to use, and well designed. In this video, I install the latest version and check it out.
Check out episode #21 of the Homelab Show podcast! This time around, the focus is on Synology. Tom Lawrence and I will talk about the features we love the most, and all sorts of things Synology-related. Don’t miss it!
Manjaro recently released version 21.1 of the popular Arch-based distribution, and in this video the community and I will review the GNOME edition together, Live! Viewers will be able to help me test it out and it’s going to be a TON of fun.
Note: Due to technical difficulties at the beginning, the actual review starts at 06:09.
In this episode of Linux Essentials, we explore the sed command. sed, aka the “stream editor” is an underused command, and that’s a shame because it’s extremely useful for manipulating text. In this video, I’ll show you the basics of the sed command.
System Administrator Appreciation Day is a special day of recognition that occurs on the last Friday of July each year. SysAdmin Day is intended to bring recognition to all the hard work that System Administrators perform to keep our systems running. In this video, I discuss SysAdmin Day (as well as many other topics surrounding the line of work) with Joao Correia from CloudLinux, and Brian from Admin Magazine. This was an awesome discussion, so don’t miss out!
I had a chance to sit down with Joao Correia from CloudLinux and Brian Osborn from Admin Magazine to talk about System Administrators Appreciation Day, System Administration in general, and why we need to help our Admins feel more appreciated it.
In this episode of Linux Essentials, we take a look at group management. You’ll see commands such as groupadd and groupdel in action as we navigate concepts around adding groups, removing groups, assigning/removing users to groups, and more!
