NAME
       dns2tcpd - A tunneling tool that encapsulate TCP traffic over DNS.

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

       -h     Help Menu

       -F     Run in foreground

       -i IP address
              IP address to bind (default 0.0.0.0)

       -p pidfile
              File where our pid will be written

       -d debug level
              Change debug level. Levels available are 1, 2 or 3.

CONFIGURATION FILES
       By default ${HOME}/.dns2tcprcd is used if no configuration file is
       specified. The resource syntax is <resource-name>:<server>:<port>.
       Multiple resources can be defined in multilines, but must be comma
       separated.

       Here is an example :

              listen = 127.0.0.1
              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
