Hmm. I assumed this worked like torsocks in that it would direct traffic through the locally running tor daemon. However, I've noticed that if I stop the locally running tor daemon, oniux still works whilst torify and torsocks do not. [edit] The documentation does actually say this. Pretty neat.

It works inside docker as well, but I needed to use --privileged. Just copied the binary into a debian:12 container and it works there:

  docker run -it --rm --privileged -v "$PWD/oniux:/usr/bin/oniux" debian:12
