A bit delayed, the interactive application firewall OpenSnitch package in Debian now got the latest fixes ready for Debian Bookworm. Because it depend on a package missing on some architectures, the autopkgtest check of the testing migration script did not understand that the tests were actually working, so the migration was delayed. A bug in the package dependencies is also fixed, so those installing the firewall package (opensnitch) now also get the GUI admin tool (python3-opensnitch-ui) installed by default. I am very grateful to Gustavo Iñiguez Goya for his work on getting the package ready for Debian Bookworm.
Armed with this package I have discovered some surprising connections from programs I believed were able to work completly offline, and it has already proven its worth, at least to me. If you too want to get more familiar with the kind of programs using Internett connections on your machine, I recommend testing apt install opensnitch in Bookworm and see what you think.
The package is still not able to build its eBPF module within Debian. Not sure how much work it would be to get it working, but suspect some kernel related packages need to be extended with more header files to get it working.
