Basically, I'm attempting to rdesktop from home over a ssh session. If
I start it up as such:
ssh -g -L 3389:server1:3389 localbox
I get to server server1 through the command
desktop$ rdesktop localbox
That works fine, but since MS RDP protocol is braindead and will listen
on 3389/tcp only, I can't figure out how to connect to server2 on port
3389 without tearing down the session and starting it all over again.
I've tried doing the ~C during the session and adding -L
3389:server2:3389, but ssh complains that ain't happening. I've
attempted to de-allocate forwarding with -L 3389:, but, again, no joy.
You didn't say whether rdesktop is braindead, too? If it's not
braindead you could do ssh -g -L 3390:server2:3389 localbox and do
rdesktop localbox 3390 for the second server.
I did a Google and it seems there are patches out there to allow
rdesktop to use different ports, probably for situations just such as
