UPDATERS(4)                                                        UPDATERS(4)



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 NIS databases.  Each entry in the file is a make target for a
     particular NIS database. For example, if there is a NIS database named
     passwd.byname that can be updated, there should be a make target named
     passwd.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 4 and 6)

     ⊕  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 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>.
