<strong>Summary:</strong>
<p>The project implements the Super Tunnel Daemon, a tunneling
daemon using plugins for different encapsulations and
automagically selecting the best encapsulation in each
environment. When the environment changes, the user should not
notice the transition to a different encapsulation except for
a small delay. Connections established within the tunnel
shall seamlessly migrate to a different encapsulation. In this
way, mobility is supported as well, even to the extent of
changing between different physical network interfaces,
e.g. disabling the wireless interface and plugging in an
ethernet cable. New encapsulations can easily be added in the
future using the plugin interface.</p>
<p>The daemon and several plugins have been written. The daemon
now has multi-user support, i.e., one server supports multiple
clients. Plugins implemented so far are UDP, TCP, ICMP,
DNS. There are also sys patches allowing to listen on all
DNS. There are also sys patches allowing it to listen on all
unused UDP and TCP ports as well as processing ICMP echo
requests in the user space.</p>
