Re: X-11 forwarding, ssh, multiple hosts

[Richard Fifarek <rfifarek@silug.org>]

	Probably could use a little more explination:

	rfifarek -> host1 works
	host1 -> host0 works
	rfifarek -> host0 doesn't work (firewall'd/private net/whatever)

	By doing the below, then
	rfifarek -> host1 -> host0 works.

	Ssh.com's ssh syntax is slightly different, but it works fine as 
well.

	Also, you need to keep the first connection up and running in 
order for this to work, otherwise it will tear down the tunnel.
