To start such a connection, run the following command in your terminal.
$ ssh -D 1337 -q -C -N user@ma.ttias.be
What that command does is:
-D 1337: open a SOCKS proxy on local port :1337. If that port is taken, try a different port number. If you want to open multiple SOCKS proxies to multiple endpoints, choose a different port for each one.
-C: compress data in the tunnel, save bandwidth
-q: quiet mode, don’t output anything locally
-N: do not execute remote commands, useful for just forwarding ports
user@ma.ttias.be: the remote SSH server you have access to
