# Short-Description: Dns2tcp is a tool for relaying TCP connections over DNS
# Description: Dns2tcp is a tool for relaying TCP connections over DNS. There is no
#              authentications nor encryption mecanisms : DNS encapsulation must be
#              considered as an unsecure and anonymous transport layer. Ressources should
#              be public external services like ssh, ssltunnel ...
