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] [-t trace_file] [-p port#] [-S] nameserver
...
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 namedomain
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.
- -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
``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(8)
but will be used to determine when to verify
the NS records. See the ``stubs'' directive in named(8)
for
more information.
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.
