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#] nameserver...

DESCRIPTION

named-xfer is an ancillary program executed by named(1M) to perform an inbound zone transfer. It is rarely executed directly, and then generally by system administrators 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 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 the zone selected for transfer.  If the SOA resource record received from the specified remote nameserver(s) does not have a serial number higher than one specified with this option, 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 file uses the prefix xfer.ddt.  and is located in the /var/tmp directory.  Note this option 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 when debugging the name server itself. 

−p Use a different port number.  The default is the standard port number as returned by getservbyname(3) for service “domain”.

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.
