An
SSH service that provides secure and
encrypted connections to traditionally
non-encrypted services, such as
e-mail or news. SSH
port forwarding
allows you to establish a secure SSH session and then
tunnel TCP connections through it. It works by opening a connection to forward a
local port to a remote port over SSH. The client
software
(e.g. your e-mail client) is then set to connect
to the local port. With SSH port forwarding
passwords are sent over an encrypted connection. Also called
SSH tunneling.
