updaters(4)                       NFS 5.4.2                      updaters(4)


NAME
       updaters - configuration file for NIS updating

SYNOPSIS
       /etc/yp/updaters

DESCRIPTION
       The file /etc/yp/updaters is a makefile (see make(1)) which is used
       for updating NIS 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 NIS database. For example,
       if there is an 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 bullets four
       and six, below):

       ⊕  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 NIS error code
       described in <rpcsvc/ypclnt.h>.
