The world's best OS Family
Tutorial
If you, like me, choose to deploy your operating systems via PXE boot using FOG Project instead of Microsoft's WDS/MDT, good for you! There are literally dozens of us! I recently discovered, having changed the IP address of the underlying OS (Debian, of course) that FOG itself
Proxmox
I won't lie, this post is in large part for my own benefit. I set up a lot of Proxmox systems, and there are a few steps that need to happen for hardware passthrough to work correctly. This is the quick and dirty guide to get it working.
Tidbit
This may be the shortest post I ever make. Sometimes a disk fights with you, and all you want to do is quickly obliterate the entire partition table & every partition on it. The command I have found to work the vast majority of the time, even when dealing with
Linux
Say we have a system where we need a single encrypted drive for all our rare and expensive Linux ISOs. Say we don't want to enter a password to decrypt the drive every time we boot. Say in the event the drive gets stolen or tossed, we don&

I was searching for an image of a progress bar and found this. So there's that. Irrelevant cover photos aside, It is in fact possible to set up Debian to automatically update all of the things and reboot if necessary. Is it smart? Probably not. Do I use

Hehe... the photo is of a shell. Get it? Like Secure SHell? It was funnier in my head. Anyway, the two most common ways to access a remote computer CLI via SSH is using a username and password, or using certificates. Certificates are far more secure, and not nearly as

I used Debian a lot. Occasionally I get oddball locale issues. This is the code I use to fix said issues. It effectively strips out all the locales except en_US.UTF-8 Technically this is not best practice, as there is a small chance it will cause issues under certain
Linux
I've done a lot of experimenting, and I have found a really great combination of settings for Proxmox to optimize the performance of Linux-based VMs. It's not as difficult as wrangling Windows VMs but there are a few potential pitfalls to avoid. Let's get

Recently we had some electrical work done on the NOC. The Air Conditioning had to be disconnected for a few hours, and we watched the temperature in our Server room slowly creep up. It got us thinking; Is there an easy (and cheap) way for us to get alerts about

fail2ban is a magical little program that does precisely what it says on the tin. Fail to authenticate properly enough times, and you'll be banned. Banned from what? Well, just about anything. fail2ban is super flexible; It reads log files and executes commands when certain conditions are met,

I was digging through logs with journalctl --since=yesterday to verify our Proxmox servers were good to go, and I saw plenty of nonsense. When in doubt, I tend to skim for the bright red things that say Error. There were more than zero, and some were a tad concerning.
Docker
Docker is awesome, and a ton of projects can be spun up in just a few minutes using Docker Compose. Many of these primarily use a Web UI, meaning the entire graphical interface exists within the browser. Unfortunately, most of the time these UI use plain HTTP, which is vulnerable
