Remote Desktop through multiple ssh tunnels (A - B - C)

You will only need one tunnel, since there is only one machine in the middle.

1. Connect from A to B using SSH, with a local tunnel from :<portX> to <machineC>:3389.

   Depending on your SSH client:

   • OpenSSH – ssh -fN -L<portX>:<machineC>:3389 <machineB>

   • PuTTY – source port <portX>, destination <machineC>:3389, type local.

     PuTTY also accepts the same -L option when run from command line.

2. Connect from A to localhost:<portX> using Remote Desktop.

   • Windows Remote Desktop – enter localhost:<portX> in the Computer box.

     Or run mstsc /v localhost:<portX>.

Here <portX> is any port between 1024-65535, and not yet in use by machine A.
