Opensnitch, the application level interactive firewall, heading into the Debian archive
22nd January 2023

While reading a blog post claiming MacOS X recently started scanning local files and reporting information about them to Apple, even on a machine where all such callback features had been disabled, I came across a description of the Little Snitch application for MacOS X. It seemed like a very nice tool to have in the tool box, and I decided to see if something similar was available for Linux.

It did not take long to find the OpenSnitch package, which has been in development since 2017, and now is in version 1.5.0. It has had a request for Debian packaging since 2018, but no-one completed the job so far. Just for fun, I decided to see if I could help, and I was very happy to discover that upstream want a Debian package too.

After struggling a bit with getting the program to run, figuring out building Go programs (and a little failed detour to look at eBPF builds too - help needed), I am very happy to report that I am sponsoring upstream to maintain the package in Debian, and it has since this morning been waiting in NEW for the ftpmasters to have a look. Perhaps it can get into the archive in time for the Bookworm release?
