UPDATERS(4)							   UPDATERS(4)

NAME    [Toc]    [Back]

     updaters -	configuration file for NIS updating

SYNOPSIS    [Toc]    [Back]

     /var/yp/updaters

DESCRIPTION    [Toc]    [Back]

     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)

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

     o	Kind of	update (an integer)

     o	Number of bytes	in key (an integer)

     o	Actual bytes of	key

     o	Number of bytes	in data	(an integer)

     o	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>.
