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

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
