What I propose is an option that allows torsocks to accept inbound connection thus listen()/accept(). An option in the configuration file and an environment variable also (which adds a command line option to torsocks as well). What about "AllowInbound" or "AllowListen" or "AcceptListen" that is off by default. Thoughts? > > *do we need to do anything about fds transferred over Unix sockets? > Probably. Right now, torsocks detects that and stops everything! Since we have no way of handling that already connected socket inside the torified application, the behavior is to abort, abort and abort...
