Headless.. this doesn't look easy as I have no way to diagnose ...
The file in /var/lib/logmein-hamachi/h2-engine.cfg or create own h2-engine-override.cfg of editing Conn.PxyXXX, won't work like Windows, even the command line has only proxy-pass (not sure what's that mean).
Do you find some useful documentation or tutorial available for using on linux?
Thanks,
