SSH Tunneling

From Computing and Software Wiki

Tunneling is the process by which one network is able to send its data using another network's connections. This process allows you to transmit otherwise insecure TCP traffic in a secure fashion by placing an entire packet within another packet and sending it over a network. An SSH tunnel is an encrypted network tunnel created using an SSH connection. This type of tunnel is more commonly known as a VPN.

Components of a tunnel

In tunneling, a packet based on one protocol is wrapped, or encapsulated, in a second packet based on whatever differing protocol is needed in order for it to travel over an intermediary network. In effect, the second wrapper "insulates" the original packet and creates the illusion of a tunnel through which the wrapped packet travels across the intermediary network. In real-life terms, tunneling is comparable to "encapsulating" a present (the original packet) in a box (the secondary wrapper) for delivery through the postal system.
