>&#13;The system that I describe to implement VPN uses SSH and PPP. Basically
I use ssh to create a tunnel connection, and then use pppd to run TCP/IP
traffic though it. That's what makes up the tunnel.
</P
><P
>&#13;The real trick to getting ssh and pppd to play well together is the
utility written by Arpad Magosanyi that allows the redirection of
standard in and standard out to a pseudo tty. This allows pppd to talk
through ssh as if it were a serial line. On the server side, pppd is
run as the users shell in the ssh session, completing the link. After
that, all you need to do is the routing.
