     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 RFC’s 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
                 people 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
                 verify 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.
