SYNOPSISnamed-xfer-z zone_to_transfer -f db_file -s serial_no [ -d debuglevel
] [ -l debug_log_file ] [ -t trace_file ] [ -p port# ] [ -S ] name‐
Named-xfer is an ancillary program executed by named(8) 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
-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 our current copy of this zone.
If the SOA RR we get 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'' deter‐
mines 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 people
debugging the name server itself.
-p Use a different port number. The default is the standard port
number as returned by getservbyname(3) 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. the ``stubs'' directive in named(8) for more informa‐
Additional arguments are taken as name server addresses in so-called
``dotted-quad'' syntax only; no host name are allowed here. At least
one address must be specified. Any additional addresses will be tried
in order if the first one fails to transfer to us successfully.
