SSH tunnel through two servers to access a web service on port 9091

First set up so you can ssh from your PC "directly" to remote1:

In your .ssh/config put:

Host remote1
  Proxycommand ssh -q -l <myuser.on.lan1> lan1 nc -w 600 localhost 16864

Make sure netcat (nc command) is installed on lan1.

You should now be able to ssh from your pc with:

ssh <myuser.on.remote1>@remote1

once this works, use:

ssh -L8888:localhost:9091 <myuser.on.remote1>@remote1

and you have access to transmission on remote1:9091 via localhost:8888
