       NAME
             updaters - configuration file for NIS updating

       SYNOPSIS
             /var/yp/updaters

       DESCRIPTION
             The file /var/yp/updaters is a makefile [see make(1)] which is
             used for updating Network Information Service (NIS) data
             bases.

       USAGE
             Databases can only be updated in a secure network, that is,
             one that has a publickey(4) data base.  Each entry in the file
             is a make target for a particular NIS data base.  For example,
             if there is a NIS data base named publickey.byname that can be
             updated, there should be a make target named publickey.byname
             in the updaters file with the command to update the file.

             The information necessary to make the update is passed to the
             update command through standard input.  The information passed
             is described below (all items are followed by a NEWLINE,
             except for the actual bytes of key and actual bytes of date).

                   network name of client wishing to make the update (a
                   string)

                   kind of update (an integer)

                   number of bytes in key (an integer)

                   actual bytes of key

                   number of bytes in data (an integer)

                   actual bytes of data

             After getting this information through standard input, the
             command to update the particular data base should decide
             whether the user is allowed to make the change.  If not, it
             should exit with the status YPERR_ACCESS.  If the user is
             allowed to make the change, the command should make the change
             and exit with a status of zero.  If there are any errors that
             may prevent the updater from making the change, it should exit
             with the status that matches a valid NIS error code described
             in <rpcsvc/ypclnt.h>.
