SSH

Tunneling to socks proxy

From here: ssh-tunnel-socks-proxy

In short:

$ssh -D 9999 username@ip-address-of-ssh-server
Then set in Firefox to use a SOCKS proxy: “localhost", port 9999

Tunneling between any two ports

Say, you want to read aremote server webpage, but there is only ssh port open on the server. Then you can create a tunnel, like this:

$ ssh -f user@server.com -L 8080:server.com:80 -N

Now you can enter the following in your browser: http://server.com:8080

Or in general

$ ssh -f user@server.com -L my-local-port:server.com:server-port -N
