SSH Tunnelling
In this example I wanted to access the web interface for our cluster on port 8080 which was blocked
# ssh -L [local port]:localsystem:[remote port] remote-system
[david@localdesktop]$ ssh -L 8080:localhost:8080 bostonhpc.co.ukThen i could point the browser at http://localhost:8080 to access the PCM console
Setup a reverse tunnel
In this example i want to create an ssh tunnel from a node in bostonlabs to viglen
[viglen@amd-quad]$ ssh -R 2222:localhost:22 david@vhpchead.viglen.co.ukFrom the vhpchead node, I can then connect to my desktop node through port 2222
[david@vhpchead]$ ssh -p2222 viglen@localhost
