How I manage SSL certificates for my homelab with Letsencrypt and Ansible

I have a fairly sizable homelab, consisting of some Raspberry Pi 4s, some Intel Nucs, a Synology NAS with a VM running on it and a number of free VMs in Oracle cloud. All these machines run RHEL …

I love Linux. Always have, always will. I run Linux (mostly RHEL and Fedora) on a multitude of devices, from Raspberry Pi's to an old laptop functioning as a server, and VMs on my NAS.

But I have also ended up (long story) doing a lot of work on MacOS …

Why share a set of headphones between MacOS and Fedora (or another Linux)?

Calling a GraphQL API from an Ansible playbook

Cockpit and FreeIPA

A couple of years ago, I did a video on Youtube on using FreeIPA / IdM certificates in Cockpit. According to some comments (that I only saw way after the fact...), for some people, my way of doing that didn't work.

Therefore, I redid the video for RHEL7 …

Solarized colors

I like Solarized, but every now and then, I switch to a different theme just to check it out. Eventually, I'll go back to Solarized, and run into the same problem over and over:

I'll end up having this

Instead of this:

Installer USB drives

Quick blog.

The other day, I was looking for a tool to create a USB drive with multiple installer ISOs on it. Mainly, I needed a Fedora installer DVD (for my laptop, to make the switch to btrfs), and a Red Hat Enterprise Linux 8.3 DVD …

Audit logging

(Happy 2021, may it be better than 2020!)

On my tiny, Raspberry Pi based Fedora systems, I have a lot of audit messages in my journal. And I mean a lot, I mean like over 50,000 over the course of 9 days. That's over 5,500 per …
