Implementing EAP, EAP-TLS and more (mostly) from scratch 25 May 2025
The first question you might be asking yourself after reading the title of this post is “Why in the @#$%&! would you do that” If that wasn’t the first thing that came to your mind, you’re probably wondering what EAP even is and why you should be so taken aback. Don’t worry, I…
Setup a docker registry for passwordless Docker builds with GitHub/GitLab using authentik 04 Jun 2022
This post will describe how to setup a docker registry using distribution/distribution to allow for “passwordless” authentication. Now of course, this is not actually passwordless, there’s still a password. But we can (ab)use the fact that both GitLab CI and GitHub Actions give…
Integrating authentik tokens with Hashicorp Vault 06 May 2022
Recently, as I’ve been implementing authentik for more of my services, I was looking for a way to get tokens from authentik into some other systems to, for example, deploy them on machines with Puppet. Because authentik doesn’t (yet) support certificate authentication, and I…
Unlocking locked resource groups in GitLab CI 06 Sep 2021
Even though Gitlab has been around for a long time, there are still times where it can crash. Normally that wouldn’t cause any issues, besides being mildly annoying. However, when Gitlab crashes (and I mean really crashes) during a CI Build, sometimes invalid data remains in the…
Running Home-Assistant with Supervisor on Ubuntu 14 Dec 2020
Recently, Home-Assistant have changed their stance, and only “support” installations on HassOS and Debian 10 (at the time of writing this) . Normally, this wouldn’t really matter to me, as I don’t really care about having a “supported” system or not. However, they also decided,…
Automating Ubuntu Server 20.04 with Packer 27 Apr 2020
Ubuntu Server 20.04 has been out for a few days, which I think is a perfect time to build start my migration from Debian to Ubuntu. Now, with Debian, I had a nice Packer setup, that automatically builds base-images. These images have some default packages installed, some…
Upgrading to ESXi 6.5 on HP gear 26 Apr 2020
It’s been a day since vSphere 6,5 came out, and sysadmins all over the world have been updating their test systems. This works really well if you update to vCenter 6.5 first, since it has the Update Manager integrated.
IPv6 and online.net 12 Apr 2020
The experimenting # Shoutout to /u/dantho and /u/CBRJack for helping me with this I’ve recently started to mess around with IPv6, mostly for the reasons of being future-proof (somewhat), a lot of free addresses and also cause it seemed interesting. Now at home I already have…
BeryJu.org goes Colo 14 Jun 2017
# It’s colo time baby! ###### the structure of this post was totally not stolen from MonsterMuffin (<3 bb) After a recent power bill reminded me that Servers were not free to run, but rather pulled some rather big power costs behind them, I decided to downsize.
My Thoughts about Puppet 4 24 Jul 2016
This weekend I decided to upgrade my Foreman to 1.12, which finally supports Puppet 4. I was pretty excited for this, since I always try to run the latest software since April 2015 . I used this guide to upgrade my Puppet install since Foreman still supports Puppet 3, and won’t…

What we’re going to do in this Part # Continuing on from last part , we’re going to provision VMware’s ESXi. Since ESXi is based on Linux, we can actually do this without a separate server or special configuration, we just need a few files.
Getting Started with Foreman: Part 2 16 Jul 2016
What we’re going to do in this Part # Continuing on from last part , we’re going to provision Windows (7/10/Server). There are two ways to do this, Wimaging by kireevco or a WDS Server. I am going to show you the WDS way since it integrates with MDT. Also Wimaging hasn’t been…

vCenter Authentication Error 31 May 2016
Over the weekend I’ve been renmaing my Domain Controllers to fit in with the other Servers (dc1 -> dc01). The Next day, I couldn’t log into vCenter anymore with my Domain Account, neither with Windows Session Credentials nor Direct Input. I got this very cryptic error…
