Hello everybody,
I have been trying to buildup some ssh tunneling commands that would
allow me to create a ssh session to an machine behind an firewall from
an machine behind an firewall but with an public server in between. I
have spent an day trying to figure things out but without success. So I
wanted to ask for somebody help to get the right command...
I have added an attachment with ASCII art that should hopefully explain
my situation and what I would like to do.
Would somebody be willing to help me out?
Thanks in advance,
Jelle

All systems are using debian linux sid or lenny, and no firewall can be

firewall of server0
