NAME
named-xfer - ancillary agent for inbound zone transfers



SYNOPSIS
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...



DESCRIPTION
The named-xfer program is an ancillary program executed by
in.named 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 name-
domain system.



OPTIONS
- 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 the current copy of
this zone. If the SOA RR 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''
determines 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 those debugging the name server itself.

-p Use a different port number. The default is the stan-
dard port number as returned by getservbyname(3SOCKET)
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. See the
``stubs'' directive in in.named(1M) for more informa-
tion.


Additional arguments are taken as name server addresses in
so-called ``dotted-quad'' syntax only; no host names are
allowed. At least one address must be specified. If the
first one fails to transfer successfully, the additional
addresses will be tried in the order given.
