updaters(4nis)
updaters --
configuration file for NIS updating
Synopsis
/var/yp/updaters
Description
The file /var/yp/updaters is a makefile (see
make(1))
which is used for updating
Network Information Service (NIS) data bases.
Usage
Databases can only be updated
in a secure network, that is, one that has a
publickey(4bnu)
data base.
Each entry in the file is a make target
for a particular NIS data base.
For example, if there is a NIS data base 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 data base 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>.
