Hi,
I’ve been trying to set up fail2ban for jellyfin both running in docker from compose and I’m doing something wrong.
Can someone tell me what path in the docker compose file you use for jellyfin logs and what path you use in the jail.d and the filter in filter.d?
Thanks
PS. Sorry for low detail, but I’m on phone and don’t have my current conf readily available. Will provide if necessary.
Why? Fail2ban is best placed on the host closest to a network entrypoint. Unless you’re intentionally avoiding a bridged network, this isn’t going to do much for your security unless the containers are directly addressed by an attached interface and an open service.
I won’t go into a whole diatribe, but you should be running containers as single-process instances of applications. You only cause issues by cramming other process to run inside a container.
What are you using it to block, exactly?
Oh I can see how my title could be misunderstood - what I meant is that both jellyfin and fail2ban are running in (separate) docker containers. Not both services crammed.into one.
But what are you trying to use fail2ban for?
To prevent brute force login attempts into my jellyfin service.
If you plan to use fail2ban, I assume you want to make your Jellyfin accessible from the public internet. Please be aware, that large parts of the Jellyfin Backend are not properly authenticated and allow unauthorized, potential mapping of your library and even unauthorized streams.
Thank you. I did see this list before. My jellyfin instance is not exposed to the net atm., but I’m thinking of exposing it in intervals and would like to have fail2ban working when/if I do.
