‪There were some snapshots on my FreeNAS from June that didn’t get deleted. They just used up several hundred GB and I wondered where all my space went. ‬

‪Mr Robot Season 3 finished. Now I curious about things to come. ‬

I want this, too: in Iceland there is a tradition that people give each other books as Christmas presents, open them right away and read the rest of the evening while drinking hot chocolate etc jolabokaflod.org/about/fou…

freebsd-update forgot to install three files which led to me not being able to log in anymore after a reboot. Yeah ipmi. Copied the files from my machine to an iso, mounted that, copied the files to the correct location and it worked again. What a fuck up

I added today the task “Develop master plan for 2018” onto my todo-list for tomorrow… 1.5 weeks left until vacation \o/

Script to "centralize" checking for updates on FreeBSD

I have to administrate several FreeBSD-servers and I need to know which servers need updates. Eveen though I have a poudriere running, I also have a local ports-tree on the machines because they are either not using the poudriere because they are not migrated to it yet or there was some reason to have a locally compiled package. Now I want to know daily which servers need package-updates and if any server has packages that have known CVEs. Thus I update the index of the portstree daily with the following cronjob for root:

0 3 * * * portsnap -I cron updateI have several “classes” of servers, thus I want mails for every class of server. For each class I have a cronjob like this in my personal crontab (or you could put it on one of your servers): 0 6 * * 1-5 /usr/local/scripts/check_for_updates.sh class1The user needs to be able to log into each server with an ssh-key.

Yeah, the certificate from my university came and I have now officially a Magister. And in good old Magister-tradition I needed 20+ semesters ;)

And tonight I will fill out the application for starting a B.Sc.-program in Computer Science :)

Ich glaube ich habe gerade das erste Mal bewusst den Gender-* benutzt
