ssh port forwarding

SSH Port Forwarding

Example:

$ ssh -fgNL 8888:apollo:8668 dave@xdroop.dhs.org

where

• f means background after authentication
• g means permit other machines to attach to the locally-forwarded port
• N means don't run a remote command
• L 8888:apollo:8668 means listen to local port 8888, then forward it to apollo's port 8668 (note that "apollo" is resolved on the remote side, not the local one)
• dave@xdroop.dhs.org means connect as user "dave" to the system "xdroop.dhs.org"

Port-Forwarding Windows Terminal Services

# ssh -L 4000:172.17.20.100:3389 dave@pluto

Then connect to localhost:4000 with your remote desktop client.
