#logfile — Public Fediverse posts

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?

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.

I need to #compress a lot of #logfile's, so, again, tested #pbzip2 #lbzip2 #lzip #xz #pixz #pigz and #zstd.
The current winner for time/size race was "lzip -7" (which is same as plzip -7, uses all threads available). #Compression rate slightly below pixz but it's hugely faster (also has better fileformat 😉).
May have been some zstd only if it would be simple to figure out the right combo of 22 options.
