This is the main page of my own personal dokuwiki, where I collect all kinds of stuff. This might not be of relevance for you, and some of what is included here might even be a bit cryptic - but in case it helps, it helps: feel free to use it.

Main reason why I have this here: When working or just playing around with IT (i.e., servers, software etc.), I occasionally get stuck and try to find publicly available information. Yes, you can find it, but often it is outdated, not exhaustive - and a main cause for trouble is that people do not give any information about to which version of underlying software etc. their content applies. I try to do better.

You can find information on several topics here:

• Ubuntu 20.04 improvements - some things to consider after installing
• Contabo server setup - quite specific stuff if you have a (VPS) server hosted at Contabo
• Apache 2.4 setup with SSL - multi-domain setup
• Exim 4 setup with SSL, SPF, DKIM, DMARC - multi-domain setup
• UFW Firewall
• MySQL/MariaDB
• Wordpress
• Docker
• DokuWiki
• Calibre eBooks
• Home Assistant
• Symfony
• Microsoft 365

All of these pages are just „notes“ taken during configuration and setup.

• My Canyon Endurace CF 7 eTap (components etc)
• Some maintenance rules
• Packaging

• Civilization 6

• Youtube DL

Good luck and have fun!
