TBC == To Be Continued

After a longer break (you may call it parental leave), I consider resuming my blog very soon.

So, please, be patient 😉

At least, I managed to upgrade all instances. Additionally, I activated the Akismet spam filter plugin.

Stay tuned…


Einladung: Urlaub im Allgäu für erfahrene Debian-User

Schongau im Allgäu – hier ist die Welt noch in Ordnung

Welcher fortgeschrittene Debian [Edu]-Nutzer bzw. Administrator hat Lust und Zeit zu einem Ausflug ins bayrische Allgäu? Biergarten, Badeseen, Radwanderungen, Bergtouren…

Für Kost und Logis ist gesorgt – ein Reisekostenzuschuss in Aussicht gestellt.

Voraussetzung ist die Bereitschaft (und Fähigkeit), einer dortigen Schule bei der Einbindung von IGEL-Clients zu helfen, die von einem (bereits installierten) Skolelinux-Terminalserver betrieben werden sollen.

Admin’s Darling: GT5

Whenever your server runs out of disk space: it’s good to know who steals your gigabytes. Formerly I used du / | sort -n | tail -30 to get a quick impression.

Today, Andree pointed me to gt5, a mighty tool based on ncurses. Its user interface is similar to those of htop or mc. It tells a lot of disk usage, so you will know very quickly where your space has gone.

  1. stopped working (I replaced it by
  2. the account at was declined!

Such obstacles cannot be cleared in a lunch break. Moodle has been offline for months, now. I will have to decide if I will stick to that instance – or setup a new one on one of the new servers to come.
