SYNOPSIS

       dns2tcpd [ -h ] [ -F ] [ -i address ] [ -f config_file ] [ -p pidfile ] [ -d debug_level ]

DESCRIPTION

       dns2tcp  is a network tool used to encapsulate TCP communications in DNS. When connections
       are received on a specific port all TCP traffic is sent to the remote dns2tcpd server  and
       forwarded to a specific host and port. Multiple connections are supported.

       It was written for demonstration purposes

              user = nobody
              chroot = /tmp
              pid_file = /var/run/dns2tcp.pid
              domain = dns2tcp.hsc.fr
              debug_level = 0
              resources = ssh:127.0.0.1:22 , smtp:127.0.0.1:25,
