Updating the default NIS maps

Perform the following procedure when updating default maps:

1. Become NIS administrator on the master server. (Always modify NIS maps on the master server.)

2. Edit the input file for the map you want to change. In this example, it is assumed that the file resides in /etc.

3. Enter:
   
   cd /var/yp
   ./ypbuild [mapname]

   mapname is the target name of the map named in /var/yp/Makefile. Omit mapname to rebuild all default maps whose input files have been updated since the maps were last built.

   The ypbuild(1Mnis) command updates the map with the changes that you made to its input file. It also calls yppush(1Mnis) to propagate the map among the slave servers.

Simply making the dbm database for a map does not propagate it. For more information, see ``Propagating an NIS map''.
