A SOCKS proxy is an SSH encrypted tunnel in which configured applications forward their traffic down, and then, on the server-end, the proxy forwards the traffic to the general Internet. Unlike a VPN, a SOCKS proxy has to be configured on an app-by-app basis on the client machine, but you can set up apps without any specialty client software as long as the app is capable of using a SOCKS proxy. On the server-side, all you need to configure is SSH.
