Because it’s easy to accidentally run services or set up services temporarily and forget that you left them running. With UPnP being able to automatically/dynamically open ports, a firewall is just another layer of protection. You can also configure firewalls to ignore packets silently or log dropped packets, and if applications ever get new versions and end up listening on new ports, you would have to manually allow the ports. Maybe you want to have one part of an application accessible through the firewall but not another part of the application.

Plus, like you said, country blocking is another feature which personally I think is nice to have, and there are also other features too like being able to throttle connections, especially with things like fail2ban.

It’s just another layer of protection, and it ensures that everything you run is deliberate.

Seems like there is a federated solution for everything lol

There’s also a list of ActivityPub software on Wikipedia: https://en.wikipedia.org/wiki/ActivityPub#Software_using_ActivityPub

It’s important to have seperate directories for unfinished torrent downloads and complete ones, and only have sonarr pick up from the completed one

Back when I used Torrents instead of Usenet for sonarr, I had only the one folder, since Plex would generally pick up the library changes automatically anyway. I’d assume that Jellyfin is similar, although I don’t use it enough to know for sure. These days I use only Usenet for sonarr/radarr since I’m paying for Usenet and it’s excellent for automation/new content, and SABnzbd provides both incomplete and complete folders by default anyway.

You should, yes. I run a firewall (I usually use ufw) on all of my Internet-connected devices, since all of my devices run Linux. There’s not really any good reason not to in 2025.

DSLReports is gone NotebookReview is gone, and more are disappearing each year. It’s sad to see.

I love Jellyfin, but I always find something that I have a problem with when trying it, for example it has weak searching, tagging, and TV show identification compared to Plex.

I tried using it even as recent as yesterday for some searching and tagging, but it’s searching, tagging, and even TV show identification has problems and is weak in comparison to Plex. I couldn’t mass-tag certain videos which was annoying for me, I had to do it one-by-one and it ended up taking a long time, that was frustrating. Also, tags don’t show up in searches anymore because it hurts performance apparently. With that said, maybe Plex has the same limitation, but it doesn’t mean that Jellyfin has to. They are open-source, and they can be better than Plex, and in many ways they already are, but I keep running into pain points with how I want to use it, and it does feel a bit unfortunate. With that said, I’m a developer too, so I know it’s not always that simple. It’s just in some ways it feels less “complete” than Plex.

I’m still really pleased with Jellyfin though, and especially the future potential of it.

If I didn’t already have my lifetime pass, I’d use Jellyfin as my primary media server platform instead of Plex.

One of these days though, I’m sure Plex will make a mistake serious enough that it impacts me, and I’ll end up switching to Jellyfin as my main media server platform.
