ssh with localhost
Sun Nov 17 21:19:00 2002
I've not senn the alice, bob, charlie docu. but here's how you could do it.
from alice: ssh -L 4444:charlie:22 bob
now from alice again, leaving above session running
ssh -p 4444 5901:localhost:5901 localhost
then vncviewer localhost:1
You are using the first ssh session to set up a tunnel that simply gives I
direct connection from the external internet machine, to the internal hidden
The second ssh session is used purely to get the connection to the localhost
port on the vncserver.
