Updated SSH Tunnel Manager to support both nmap-ncat and legacy netcat, and fix a bug that resulted in an infinite loop in one of the connection status checkers. So far it's been performing nicely for the last few hours with several network events thrown its way from the local and remote sides of the tunnel. Not mad about it at all.
@rbrown let me know how it works for you, or if you’ve got any suggestions to improve it. It’s been running on one of my embedded systems for more than a week now without issue so I’m pretty happy with it myself.
