 rtcp - A simple port forwarder (secured)

+It setups an VPN over SSH, using similar techniques to gitolite.

+

+Objective: Setup a tun/tap interface for the VPN

+

+Server implementation notes:

+1. rtcp_server listening to an UNIX socket, is the server part, 

+   holds the tun/tap interface.

+2. has an ssh user setup with the keys of the client in the authorized_keys,

+   has the .hushlogin file in $HOME and /usr/bin/rtcp_helper as the shell

+   for the user in "/etc/passwd".

+3. the rtcp_helper connects to the server and forwards the traffic.

+

+Client implementation notes:

+1. rtcp_client is the client part.

+2. Called as "rtcp_client rtcpuser@host".

+3. Creates the client tun/tap interface and fordwars the traffic.
