updaters(4) UNIX System V updaters(4)
NAME
updaters - configuration file for Network Information Service (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. 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 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)
⊕ nctual 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>.
