       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

       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
