   zoneserver - handle zone transfers and other TCP functions for MaraDNS

                                  DESCRIPTION

   zoneserver listens on port 53/tcp and handles DNS zone transfers and any
   DNS query done over TCP instead of UDP. zoneserver uses a configuration
   file, /etc/mararc by default, to determine its parameters.

                                     USAGE

   zoneserver -f pointer_to_mararc_file

                                    OPTIONS

   -f
           Specifies the location of the configuration file. MaraDNS uses the
           same configuration file for both the main dns server and the
           zoneserver.

                           CONFIGURATION FILE FORMAT

   The file format for the mararc file can be found in the mararc(5) manual
   page. In particular, the zoneserver uses the zone_transfer_acl,
   tcp_convert_acl, tcp_convert_server, bind_address, and recursive_acl
   mararc parameters.

                                      BUGS

   zoneserver assumes that the authoritative NS records are immediately after
   the SOA record, and that there is at least one non-NS between that last
   authority NS record for the zone and the first delegation NS record.

   IXFR requests are incremental zone transfers, meaning that the DNS server
   should only display records changed since the last IXFR request.
   zoneserver, however, treats an IXFR as if it were an AXFR request,
   outputting all of the records for the zone in question.

   zoneserver closes the TCP connection after transferring the requested
   zone.

   If an unauthorized client attempts to connect to the zoneserver,
   zoneserver immediately disconnects the unauthorized client.
