I've seen a lot of posts lately about #LittleSnitch which has been on my radar for a while. It supports #Linux now which is great. But it's not fully opensource.

I found #opensnitch and wow it's great. Reminds me of what I consider to be "peak windows" days, early 2000s when the zonealarm firewall was popular.

#Nostalgia will getcha!

I saw that Little Snitch is now available for #Linux.

As far as I’m aware, there’s already #OpenSnitch for Linux.

I installed OpenSnitch today after having seen a post about it on BlueSky (I think). It's a nice application firewall which gives you even more control over what leaves your computer.

Wow oh wow. Any strategies for how to manage OpenSnitch on NixOS? It's a cool tool but the constant popups for everything that connects to the internet is just... a lot.

And, unfortunately, because of how nix works, each rule I allow via the popup assigns the /nix/store binary path to the rule, so I don't expect the rules to survive a rebuild.

I've already used it to strip out all of the advertising domains, and my next target is for blocking AI slop domains. For that alone is worth it.

So I'm the kind of wacko who has #opensnitch set up to manually filter any address my computer connects to. Despite using a base block list, browsing was absolute hell for a week until my rules covered enough ground to block most of the repeat offenders. I usually allow the domain I'm visiting and its subdomains, period.

The amount of domains one can block before a website breaks is telling. It also made me realise that with link preview enabled #Firefox and all derivatives send a request to the domain of all the links your cursors HOVERS, a.k.a brushes past which seems like a massive breach of privacy and waste of bandwidth... Note that disabling link preview requires a restart after unticking the box, which made the culprit hard to figure out at first.

Anyway, watching #Peertube is obviously quite challenging with this setup, because of the "peers" in the tube. What I don't understand is why there isn't a consistent port I can unblock, each request seem to use a random port.

Can anyone help me make sense of this please?

I wonder if #Linux users on Fediverse have heard of OpenSnitch, and if they are using it, how handy the have found it? Do you use it in daily basis? Home to work computer?
