Often when I access for example Motala via a tunnel setupa with tl-support, the tunnel is shut down before I'm done, because someone at Motala accidentally closed the wrong xterm or logged out the wrong user. tl-support should probably be able to background itself. We might even want that to be the default behaviour. Perhaps we could have a kill-switch to tl-support, that the admin can run to shut down all tunnels when he/she really wants?
This use case hasn't been relevant in many years. Closing.
