SSH Tunnelling
I just setup a SSH tunnel from my box to a distant server. It worked fine, with one minor problem.
When I first tried the tunnel, I would get timeouts on the client, and this message on the server session:
What I didn't realize is that in the command
When I first tried the tunnel, I would get timeouts on the client, and this message on the server session:
channel 3: open failed: connect failed: Connection timed outWhat I didn't realize is that in the command
ssh -TCN -L 1234:baz.bar.com:2345 foo@baz.bar.com, the first 'baz.bar.com' is relative to the host machine, not the client. As a result, the command connected to the server, but the port forwarding didn't work because the server didn't know about baz.bar.com. Using ssh -TCN -L 1234:localhost:2345 foo@bar.com did the trick, since the server did know about localhost relative to itself, and the client process connected immediately.

Wow, who would have thought that 8 years later your post would be found, and have the solution to my exact problem. Thank you. I spent the last 5 hours trying to make a simple SSH tunnel work (something I've done hundreds of times before), but for some reason, this time it was failing with very little helpful error messages. Turns out it was the EXACT problem (and solution) you stated, so I just wanted to say "thanks".
same thing! thx a lot!!!
