Dns2tcp is a network tool designed to relay TCP connections through DNS traffic. Encapsulation is done on the TCP level, thus no specific driver is needed (i.e: TUN/TAP). Dns2tcp client doesn't need to be run with specific privileges.

Dns2tcp is composed of two parts : a server-side tool and a client-side tool. The server has a list of resources specified in a configuration file. Each resource is a local or remote service listening for TCP connections. The client listen on a predefined TCP port and relays each incoming connection through DNS to the final service.

Dns2tcp is written by Olivier Dembour with the contribution of Nicolas Collignon.

Nouveauté pour la version 0.5 :

  • Identification par clé partagée
  • Exécution de commandes par le client (reverse shell DNS)
  • Support du type de requête "KEY"
  • Découverte automatique du DNS
  • Utilisable en proxy par SSH (ProxyCommand)
  • Possibilité de compiler le client pour Windows
