  • opensnitch

    OpenSnitch is a GNU/Linux interactive application firewall inspired by Little Snitch.

    • If you run a GNU/Linux desktop you could also install opensnitch on the server, and the GUI on the desktop (although you'll need to add a rule to redirect traffic from containers).

  • picosnitch

    Monitor Network Traffic Per Executable, Beautifully Visualized

    • You can use picosnitch for this, I'm the developer and this is exactly the use case I had in mind when designing it (24/7 monitoring of traffic on a per executable basis, primarily in containerized environments).
