Small infrastructure, written down so I don't have to remember it.
For two years my offsite backups ran every night without a single error. Then I tried to restore one directory and found out the repository password lived only in the machine I was trying to recover. A short post about restore drills, and why they belong in the calendar rather than in good intentions.
Read more →Most of the upgrade was boring, which is exactly how it should be. The parts that weren't: an old sources.list entry, a renamed network interface, and a cron job that quietly depended on Python 3.11. Notes, in the order things broke.
Read more →Persistent=true, randomized delays, logs in the journal and a status command that tells you when something last ran. A small migration guide with the three timers I actually use, plus the one case where I still reach for crontab.
Read more →Three networks, one cheap managed switch and a firewall config short enough to read in one sitting. Printers and TVs go in their own corner; everything else stays boring.
Read more →I look after a handful of small servers, mostly for friends and family. This site is where the notes end up. Nothing here is advice; it is just what worked on my machines.
