updaters(4)
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 NIS databases. Databases can only be updated in a secure network (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 a NIS 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 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>.
