I've got an entry in my .screenrc that goes like this:
screen ssh -nNfL 2200:remotehost:22 tunnelhost screen -t 'Launcher' ssh localhost -p 2200
This seems to start the tunnel session in screen no. 0 but then only opens a new tab on the tunnel host (screen no. 1), not the host I'm trying to tunnel to.
What am I doing wrong?
