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

Named-xfer is an ancillary program executed by named(8) toperform an inbound zone transfer. It is rarely executeddirectly, and only by system administrators who are tryingto debug a zone transfer problem. See RFC's 1033, 1034,and 1035 for more information on the Internet name-domainsystem.

Options are:

-z: specifies the name of the zone to be transferred.
-f: specifies the name of the file into which the zoneshould be dumped when it is received from the primaryserver.
-s: specifies the serial number of our current copy ofthis zone. If the SOA RR we get from the primaryserver does not have a serial number higher thanthis, 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. Thedefault is system- dependent but is usually in/var/tmp or /usr/tmp. Note that this only appliesif -d is also specified.
-t: Specifies a trace file which will contain a protocoltrace of the zone transfer. This is probablyonly of interest to people debugging the nameserver itself.
-p: Use a different port number. The default is thestandard port number as returned by getservbyname(3)for service ``domain''.
-S: Perform a restricted transfer of only the SOA, NSrecords and glue A records for the zone. The SOArecord will not be loaded by named but will be usedto determine when to verify the NS records. Seethe ``stubs'' directive in named(8) for more information.

Additional arguments are taken as name server addresses inso-called ``dotted-quad'' syntax only; no host name areallowed here. At least one address must be specified.Any additional addresses will be tried in order if thefirst one fails to transfer to us successfully.
