Have you noticed the user agent ‘Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/118.0’ in your log files? Thousands of such requests come in from 25 servers at a German provider. They look like search queries on the website as if using a form, but all quite pointless.

This has been going on for months. It doesn't really burden the server, but is a waste of resources. I don't have a good explanation. An AI bot?

Ist euch auch in den Logfiles der User-Agent "Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/118.0" aufgefallen? Von 25 Servern bei einem deutschen Provider kommen tausende solche Anfragen herein. Alle ziemlich sinnlos. Immer werden allen Resourcen der jeweiligen Webseite geladen.

Das läuft schon seit Monaten. Belastet den Server nicht wirklich, ist aber letztlich eine Verschwendung. Eine gute Erklärung habe ich nicht. Ein KI-Bot?

Dass sich (KI-)Bots 🤖 im Open-Data-Portal tummeln, ist nichts Neues. Doch heute ist mir ein besonders merkwürdiger Fall begegnet, über den ich berichten möchte.

I am sorry. Sometimes I just am THAT immature.

I came across the #Fail2Ban #docker image from #linuxserverio and thought to myself that it's finally time to set up Fail2Ban. I admit i never used it before and it was a bit difficult to add it to my #playbook as all of my #servers have different services and therefore different #logfile paths, but that's nothing #jinja #templating can't fix.

Now that i've got #Discord notifications for banned #IPs, it's time to work on actual #IPblocking. I also want to use the #IPComplaint and #AbuseIPDB actions as i really like the idea of reporting abuse (even though i have no idea how effective that may be).

I may also want to replace the discord #webhook with #email notifications later as that's mostly the reason i've set up a #mailserver ( #stalwart ) in the first place.

I mean, most of my services are only accessible from #tailscale or my #homenetwork, but since #Ansible makes it so much easier to apply higher standards, i just can't resist. My #homelab is changing every day and i think setting up additional #security, even though i don't need it yet, is never a bad idea.
