Just for fun, I tried to build the source from Chris on Bullseye, but it had a few issues. I cloned it to <URL: https://salsa.debian.org/debian/pkg-opensnitch.git > and applied a few fixed to get it to build. Sadly it is not working.
The opensnitch daemon fail to start with the following message in /var/log/opensnitchd.log: 2023-01-19 21:56:02] IMP Starting opensnitch-daemon v1.0.0b [2023-01-19 21:56:03] !!! Error while enabling probe descriptor for opensnitch_exec_probe: write /sys/kernel/debug/tracing/kprobe_events: no such file or directory The opensnitch-ui program fail to start with this error: Traceback (most recent call last): File "/usr/bin/opensnitch-ui", line 38, in <module> service = UIService(app, on_exit, args.config) File "/usr/lib/python3/dist-packages/opensnitch/service.py", line 52, in __init__ self._setup_interfaces() File "/usr/lib/python3/dist-packages/opensnitch/service.py", line 72, in _setup_interfaces namestr = names.tostring() AttributeError: 'array.array' object has no attribute 'tostring' I further tried to build the latest upstream source after importing it using uscan and gbp import-orig, but could not get it to build. Do not know the Go language enough to debug this, but I suspect the issue is new dependencies missing in Debian. -- Happy hacking Petter Reinholdtsen
