Updating existing NIS maps

After you have installed NIS, you will discover that some maps require frequent updating while others never need to change. For example, the publickey.byname map may change frequently on a large company's network. On the other hand, the auto.master map will probably change little, if at all.

When you need to update a map, you can use one of two updating procedures, depending on whether the map is a default map or a non-default map. A default map is a map in the default set created by ypinit from the network databases. ``Updating the default NIS maps'' explains how to modify these maps. Non-default maps may be any of the following:

• included with an application purchased from a vendor

• created specifically for your site

• existing in a form other than ASCII
