NAME

       updaters - configuration file for NIS updating

SYNOPSIS

       /var/yp/updaters

DESCRIPTION

       The  file  /var/yp/updaters  is a makefile (see make(1S)) which is used for updating the Network Information Service (NIS) databases. Data-
       bases 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 4 and 6):

       1.	Network name of client wishing to make the update (a string).

       2.	Kind of update (an integer).

       3.	Number of bytes in key (an integer).

       4.	Actual bytes of key.

       5.	Number of bytes in data (an integer).

       6.	Actual bytes of data.

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

       name  has  changed. The name Yellow Pages is a registered trademark in the United Kingdom of British Telecommunications plc, and may not be
