alt Hacker NewsI typically just create a "new" connection in a separate tab when I want to add tunneling.
I put new in quotes because I use another little-known feature, "ControlMaster". Multiplexes multiple connections into one, it makes making " new" sessions instant (can also be configured to persist a bit after disconnecting). Also useful for tab-completing remote paths. It does not prompt for authentication again, though. And it's a bit annoying when the connection hands (can be solved with ssh -o close, IIRC).

I'm using that as well but had issues with tunneling where it creates the tunnel in the background and terminates and so you might not know the random port it assigned or I couldn't figure out how to un-tunnel it and tunnel again to the same port. Just bypassed the control master then.
TIL; thanks, that's interesting (and somehow escaped my 20+ years of using ssh)! As usual the gold is in the comments :-)

Is this what secureCRT used as well? I remember this being all the rage back when I used windows, and it allowed this spawn new session by reusing the main one.
