May I ask what I should look for in the log files to detect this (and so I can configure fail2ban correctly)?

For all German speakers I have a beginners guide: https://github.com/PCJones/usenet-guide

Usenet is the secret for German stuff. I have a German beginners guide: https://github.com/PCJones/usenet-guide

sceneNZBs for German content. Will have everything you need :)

If you are using Radarr & Sonarr and want to prefer German DL (Dual Language, German + Original) releases I have a guide for that: https://github.com/PCJones/radarr-sonarr-german-dual-language

Also since it looks like you are new to using the Usenet, I have a German beginners guide: https://github.com/PCJones/usenet-guide/

You might want to have a look at Usenet. Yes, it costs money but it's such a premium experience compared to torrents and you don't have to care about seeding etc at all

If you are looking for German (or German + English dual language) content it can be very hard to find stuff on public torrent trackers and it's pretty hard to get onto private German trackers - but don't worry, there is a solution:

Usenet and the indexer sceneNZBs.com that specialises in German releases have got you covered!

If you want to automate the search for German Dual Language content using Radarr/Sonarr I made a guide (that also works for torrents too): https://github.com/PCJones/radarr-sonarr-german-dual-language

I already responded to you on reddit, but for Usenet you really don't need a VPN, only for torrents. I also told you to just use Radarr, Sonarr, Prowlarr and SABnzbd but since you also want something to play the items definitely keep Jellyfin. I also recommend to keep Jellyseerr as it's a great way to request and find new movies and shows.

I'll paste my original response from reddit here just in case someone else is looking for the same thing:

Assuming you want to fully automate it by using Sonarr and Radarr you can use my fork of docker-media-center which has SabnZBD for Usenet downloads:

https://github.com/PCJones/docker-media-center

Sadly I haven't got the time yet to update the documentation but if you know docker you should be able to figure it out, if not I'll gladly help.

You'll want to remove all services you don't want from the docker compose file (so for a simple Usenet Setup you'll only want Radarr, Sonarr, Prowlarr, SabnZBD).

Important stuff missing from the documentation:

• the git clone link in the documentation is still pointing to the original repository, make sure to clone mine

• at some point docker will tell you that it can't find the network global or local (one of these, I forgot which. But it'll tell you) When that happens all you have to do is execute docker network create global (or local)

• after starting all services (especially SabnZBD) you'll need to execute the file set_sabnzbd_hostname.sh once and then restart the SabnZBD container.

• In the sabnZBD Folder settings you'll need to set the temp folder to data/temp (it doesn't have to be temp, you can chose another name).

• In the sabnZBD Folder settings you'll need to set the completed download folder to data/downloads

• In the sabnZBD Categories settings you'll need to set the Folder/Path to data/downloads/radarr for movies and to data/downloads/sonarr for TV and anime

• you'll have to add sabnZBD as download client in both Radarr and Sonarr. Just use sabnzbd as hostname

Once set up and configured it works like a charm.

And again, if you need assistance just let me know and I'll help

It's the same, it just adds support for jellyfin

The provider is there to access the usenet, just like you pay your internet provider to access the internet (well, not exactly like that in a technical sense, but you get what I mean I hope). And yes, while there are some free indexers they are basically useless - so you do have to pay for both, usenet access and an indexer. It should still be cheaper than a seedbox though.

To start I’d recommend frugal Usenet for 40$ a year if you are mostly downloading new stuff:

If you are also downloading a lot of older (think 10+ years) stuff you should get ewaka for 48€/year (or keep an eye out for the 36€ year deal that pops up a few times per year):

Let me know if you need more help :)

edit: good indexers to start are NZBgeek (open registration) or Drunkenslug (closed registration, but there are a lot of invites going around). Both cost 15-20€ per year

They are obfuscated and encoded so it's not easy to find the files. Since they are encoded they basically look like random noise instead of actual video files (very simplified)

Looks like first and foremost you need a good(that means paid) indexer. NZBgeek and Drunkenslug come to mind as a good start - they both cost 15-20€/year. Drunkenslug registrations are closed right now but there are a lot of invites floating around. NZBgeeks registration is open.

I know this is not exactly what you are looking for, but the Usenet indexer https://scenenzbs.com/ is specialised in German (+ German/English Dual Language) releases. Registration is open. They have a lot of stuff, not everything if it's older or rare, but enough. For new stuff it's perfect and there is basically everything.

Let me know if you need help setting it up, this is the best way to get German content if you don't have access to a private tracker.

PS: If you are looking for a German dual language Radarr/Sonarr setup I made a guide for that (works for public torrent trackers too, but as you said - there isn't a lot of German content on them): https://github.com/PCJones/radarr-sonarr-german-dual-language
