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
       Named-xfer is an ancillary program executed by named(8) 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 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 pri-
              mary server.

       -s     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     Print  debugging  information.   A number after the
              ``d'' determines the level of messages printed.

       -l     Specifies a log file for debugging  messages.   The
              log file will be written in the directory specified
              in named.boot (which is /var/named in  the  default
              configuration).   Note that this only applies if -d
              is also specified.

       -t     Specifies a trace file which will contain a  proto-
              col  trace  of the zone transfer.  This is probably
              only of  interest  to  people  debugging  the  name
              server itself.

       -p     Use  a  different  port number.  The default is the
              standard port  number  as  returned  by  getservby-
              name(3) 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 named(8) for more infor-
              mation.

       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.
