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

	      port = 53
	      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,
			   pop3:10.0.0.1:110
