Socks tunnel

ssh -D 8123 -f -C -q -N

-D: Tells SSH that we want a SOCKS tunnel on the specified port number
-f: Forks the process to the background
-C: Compresses the data before sending it
-q: Uses quiet mode
-N: Tells SSH that no command will be sent once the tunnel is up

Verify that the tunnel is up and running:
ps aux | grep ssh

If using -f close the tunnel
kill <process id>
