Where LittleSnitch is definitely ahead is showing process connections over time after said process has been allowed.
As software should be.
> You can find Little Snitch for Linux here. It is free, and it will stay that way.
Don't worry, the authors know that there's no point in charging Linux users. Unlike Mac users.
So you might as well make it $0 and the (Linux) crowd goes wild that they don't need to pay a cent.
However...
> I researched a bit, found OpenSnitch, several command line tools, and various security systems built for servers. None of these gave me what I wanted: see which process is making which connections, and in the best case deny with a single click.
OpenSnitch is open source. You don't need to trust it as you can see the code yourself. Little Snitch on the other hand, is completely closed source.
Do you still trust them not to do self-reporting or phoning home, even though it is $0 and closed source?
If you trust Little Snitch on Mac, then yes.
They've been in business for over 20 years. They're not going to blow their entire business and reputation for a few Linux users.
I do wonder however, are they sufficiently careful about their processes and own machines to avoid a supply chain attack completely.
They must be a target for the various hacking groups out there.
A supply chain attack doesn't directly attack an end developer but rather a supplier of the developer. So who or what is the supplier in this case?
No, not really. And I disagree with the premise, "They must be a target for the various hacking groups out there."
How would you even hack them? I'm a developer too; how would you hack me?
I'm not even going to respond to this ridiculousness.
I still don't know why anyone thinks that, among all developers in the world, a little indie Mac developer is getting targeted specifically.
There's not one single way, so, no, you're just hand-waving here.
The comment was asking about preventing a compromised supplier for the developers.
A supply chain attack can be anywhere in the supply chain to the target. If I, the end user, am the target, then a supply chain attack compromising the developer of LittleSnitch is effective.
I may then be a conduit to compromising other software or components, and would both I and LittleSnitch would be part of the supply chain that could be attacked targeting them.

I've been a GlassWire user for years, which partially fills the role of LS, but not very well. Aside from the many performance issues I've seen, it's missing a lot of LS essentials. To be fair, I think the focus of GlassWire is more about visualizing traffic on your Windows computer, but I definitely believe there is a need for better Windows network software for power users.

> The macOS version can make stronger guarantees because it can have more complexity. On Linux, the foundation is eBPF, which is powerful but bounded: it has strict limits on storage size and program complexity. Under heavy traffic, cache tables can overflow, which makes it impossible to reliably tie every network packet to a process or a DNS name.
> And reconstructing which hostname was originally looked up for a given IP address requires heuristics rather than certainty. The macOS version uses deep packet inspection to do this more reliably.

Have you ever checked Calico or Cilium, or at least, Oryx?
pi.hole is primarily billed as an ad blocker, but the fundamental way it works is by applying a curated set of DNS lists that are blocked (commonly telemetry and ad servers), and the admin dashboard which is just a web page (therefore works on all platforms, smartphones included) will do the same thing: it tells you every call that every app on every device on your network is making, and you can approve or deny it. You can curate your own list as well and block servers/connections you don't want on the network.
LS afaik operates in the same area where it's intended to be used for privacy. I guess I could see it being useful for people who don't have admin access to their router, but for people who do have such access I would think the benefits of network-wide DNS monitoring/blocking would outweight the costs of having to configure your router settings.
Worth noting that it is closed source. Would be worth contributing patches to OpenSnitch to bring it up to parity with Little Snitch.
Isn't MacOS just *nix under the hood? Genuinely curious about this difference.
