Description Pierre Ossman cendio 2017-02-08 15:16:07 CET
Right now we forcefully terminate any process that has a port open that we'd like to grab for local device tunnelling. For older systems this is the old method to free up a port, but newer kernel supports just killing the socket. E.g. this command will kill anything listening on port 6023:

    $ sudo ss -K -a sport = :6023

This method could severely reduce the impact of ThinLinc stealing back ports.
Comment 1 Pierre Ossman cendio 2017-02-14 10:21:16 CET
RHEL 7's ss doesn't seem to have this, at least not right now. So it's very new systems that would be required.
