updaters(4)                                                     updaters(4)

NAME
     updaters - configuration file for YP updating

SYNOPSIS
     /var/yp/updaters

DESCRIPTION
     The file /var/yp/updaters is a makefile [see ypmake(1M)] which is used
     for updating YP databases. 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>.
