named-xfer - ancillary agent for inbound zone transfers

The named-xfer program is an ancillary program executed by in.named to perform an inbound zone transfer. It is rarely executed directly, and only by system administrators who are trying to debug a zone transfer problem. See RFC's 1033, 1034, and 1035 for more information on the Internet name- domain system.


-z Specifies the name of the zone to be transferred. -f Specifies the name of the file into which the zone should be dumped when it is received from the primary server. -s Specifies the serial number of the current copy of this zone. If the SOA RR from the primary server does not have a serial number higher than this, the transfer will be aborted. -d Print debugging information. A number after the ``d'' determines the level of messages printed. -l Specifies a log file for debugging messages. The default is system- dependent but is usually in /var/tmp or /usr/tmp. Note that this only applies if -d is also specified. -t Specifies a trace file which will contain a protocol trace of the zone transfer. This is probably only of interest to those debugging the name server itself. -p Use a different port number. The default is the stan- dard port number as returned by getservbyname(3SOCKET) for service ``domain''. -S Perform a restricted transfer of only the SOA, NS records and glue A records for the zone. The SOA record will not be loaded by named but will be used to determine when to verify the NS records. See the ``stubs'' directive in in.named(1M) for more informa- tion. SunOS 5.8 Last change: 13 Feb 1997 1 Maintenance Commands named-xfer(1M) Additional arguments are taken as name server addresses in so-called ``dotted-quad'' syntax only; no host names are allowed. At least one address must be specified. If the first one fails to transfer successfully, the additional addresses will be tried in the order given.
