About This Guide

The NIS Administration Guide documents the Silicon Graphics® implementation of the network information service NIS. NIS is adapted from Sun Microsystems, Inc.'s 4.0 release of NIS, with bug fixes from release 4.1. This guide was prepared in conjunction with the release of IRIX™ Release 5.1.

NIS is a database service that provides location information about network entities to other network services, such as NFS. Systems with heterogeneous architectures and operating systems can participate in the same NIS. The service can also include systems connected to different types of networks.

This guide was formerly published under the title NFS and NIS Administration Guide and Man Pages, and documented the Network File System, NFS™, as well as NIS. Information about NFS is now published in a separate volume called the NFS Administration Guide.

Using This Guide

The purpose of this guide is to provide the information needed to set up and maintain NIS. It explains the software fundamentals of the product and provides procedures to help you install, test, and troubleshoot NIS on your network. It also contains recommendations for planning and administering NIS.
