Setting up SSH Tunnels
First make sure you a route set to bambam from the machine you wish to access usually something like Route add bambam rt1 The set up a putty ssh connection to Bambam (use different remote port. Port 9876 is only an example and can used by only 1 person on Bambam!) See below…. While logged into BAMBAM in the ssh session connect to the remote system using the command below:
Ssh –C –L :: -l ssh -C -L 55643:10.157.144.183:70 -l root 172.20.161.114
From your laptop you can now connect to the service using the localhost address connect web browser to
`http://127.0.0.1:70. login as: squantri squantri@10.224.177.36’s

This can also be used to access a service running on a different port for example, say you have connected to a system on 81.52.180.2 and the service is running on 10.157.144.183 then you need to use the same technique with putty connect using tunnels as before only instead of to bambam you goto the 81.52.180.2 address once there issue the
ssh command ssh -C -L 55643:10.157.144.183:70 -l root 81.52.180.2
this will allow you to use you local laptop to view upower and any other service running on the other port once the ports are set up.. setting up to port 20550 you can browse the mmh ssh -C -L 55643:10.157.144.183: 20550 -l root 81.52.180.2 127.0.0.1:70/mmh/info 127.0.0.1:70/mmh/messagebrowser
