updaters(4N)                                                   updaters(4N)


   NAME
         updaters - configuration file for YP updating

   SYNOPSIS
         /var/yp/updaters

   DESCRIPTION
         The file /var/yp/updaters is a makefile (see make(1)) which is used
         for updating YP databases.  Databases can only be updated in a secure
         network, that is, one that has a publickey(4) database.  Each entry
         in the file is a make target for a particular YP database.  For
         example, if there is a YP database 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 database should decide whether the user is
         allowed to make the change.  If not, it should exit with the status
         YPERRACCESS.  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 YP error code
         described in <rpcsvc/ypclnt.h>.
