Using OpenSSH with a ssh Proxy

Here is how you can set up ssh on your linux machines to automatically bounce from one host to the next.  I believe that using a modification of this could work to use a regular proxy but I have to research that.

Add this to ~/.ssh/config
Host internethost.com
ProxyCommand ssh -a -x sshrelay.com "nc internethost.com 22"

Where sshrelay.com is a ssh machine with better internet access to the remote host and internethost.com is the final destination.  Now I just have to type 'ssh internethost.com' to get all the way through to the final machine.  I can now forward X sessions, use scp, use FreeNX, with an easy configuration.
