SSH tunnelling

ssh -N -f -R 14443:localhost:22 [email protected]

-N do not execute a remote command, useful for just forwarding ports -f put ssh in background -R reverse tunnel (port 14443 on destination tunnels to localhost:22)

Dynamic port forwarding so we can use localhost:1080 as a proxy in ssh

to access machines reachable from tembusu

Host tembusu DynamicForward localhost:1080

expose cfs1.cl.comp.nus.edu.sg:2049 as localhost:3049 so we can mount

localhost:3049 using NFS

ssh -fN -L 3049:cfs1.cl.comp.nus.edu.sg:2049 tembusu
