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-
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.
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.
Print debugging information. The debuglevel is a number
determines the level of messages printed.
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.
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.
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.
Specifies the IPv4 source address to use for this query.
Specifies the IPv6 source address to use for this query.
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
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
