Re: [ssh-l] Network tunneling

Ok, I figured it out for myself. To do this, I had to do a few things :

1. Compile the new version of ssh, since my version (2.9p2) had a bug.
2. Add GatewayPorts yes
3. The following command from the Client1 then works to make a loop :
  ssh -g -C -L 6002:Server1:6008 -R 6008:Client1:6000 Server1

where the following command will show up on my local X server (:0) :
  xterm -display Client:2

So the answer to my question is no, sshd does not need to be run on both
machines.

Thanks,
Brian
