     named-xfer - ancillary agent for inbound zone transfers

     named-xfer -z zone_to_transfer -f db_file -s serial_no [-d debuglevel]
		[-l debug_log_file] [-i ixfr_file] [-t trace_file] [-p port#]
		[-C class] [-S] [-q] [-x ipv4_src_address]
		[-X ipv6_src_address] [-T tsig_file] nameserver [axfr | ixfr]

     Named-xfer is an ancillary program executed by named(8) to perform an
     inbound zone transfer.  It is rarely executed directly, and then only by
     system administrators who are trying to debug a zone transfer problem.
     See RFCs 1033, 1034, and 1035 for more information on the Internet name-
     domain system.

     Options are:

     -z zone_to_transfer
		 specifies the name of the zone to be transferred.

     -f db_file  specifies the name of the db_file into which the zone should
		 be dumped when it is received from the primary server.

     -s serial_no
		 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 debuglevel
		 Print debugging information.  The debuglevel is a number
		 determines the level of messages printed.

     -l debug_log_file
		 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.

     -i ixfr_file
		 Specifies the name of the ixfr_file into which the zone
		 changes from Incremental Zone Transfer (IXFR) should be
		 dumped when it is received from the primary server.

     -t trace_file
		 Specifies a trace_file which will contain a protocol trace of
		 the zone transfer.  This is probably only of interest to peo
		 ple debugging the name server itself.

     -p port#	 Use a different port number.  The default is the standard
		 port number as returned by getservbyname(3) for the service

     -C class	 Defines which class to use.  Defaults to IN.

     -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(8) but will be used to determine when to ver
		 ify the NS records.  See the stubs directive in named(8)
		 for more information.

     -q 	 Tells named-xfer to be quiet.

     -x ipv4_src_address
		 Specifies the IPv4 source address to use for this query.

     -X ipv6_src_address
		 Specifies the IPv6 source address to use for this query.

     -T tsig_file
		 Specifies a file to transfer TSIG information to named-xfer.
		 Multiple entries of the following format:

		 IP address  When connecting to this address use this TSIG
		 key name
		 algorithm   157 (HMAC-MD5) is the only algorithm supported.
		 key data    base64

		 named-xfer expects this file to be temporary in nature and
		 will explicitly delete this file after its use.

     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.  The axfr
     or ixfr after name server address designates the type of zone transfer to
     perform.  Use axfr for a full zone transfer or ixfr for an incremental
     zone transfer.
