The ONC3/NFS Administrator's Guide documents the Silicon Graphics® Open Network Computing/Network File System (ONC3/NFS). ONC3/NFS™ is adapted from Sun Microsystems, Inc.'s ONC+™ version 1.2, and was previously referred to as the Network File System (NFS). The purpose of this guide is to provide the information needed to set up and maintain the ONC3/NFS services. It explains ONC3/NFS software fundamentals and provides procedures to help you install, test, and troubleshoot ONC3/NFS on your network. It also contains planning information and recommendations for administering the service.
ONC+ has been optimized for use on Silicon Graphics systems, and has been integrated with the IRIS Indigo Magic™ environment and system toolchest. The Silicon Graphics implementation of ONC+ can run only on a Silicon Graphics system.
ONC3/NFS is made up of distributed services that allow users to access file systems and directories on remote systems and treat them as if they were local. Networks with heterogeneous architectures and operating systems can participate in the same ONC3/NFS service. The service can also include systems connected to different types of networks.
The components of ONC3/NFS are described below. Further information is provided in the following chapters.
Table 1 contains a summary of each chapter in this guide and suggests how to use the chapter.
Table 1. ONC3/NFS Administrator's Guide Chapter Summaries
Chapter | Summary | When to Read |
|---|---|---|
Introduces the vocabulary of ONC3/NFS, and the fundamentals of ONC3/NFS operation. | Read this chapter if you are new to ONC3/NFS. If you already have ONC3/NFS experience, you can skip Chapter 1. | |
Explains ONC3/NFS processes and their options in detail. | You should be thoroughly familiar with the information in this chapter before continuing with Chapter 4, “Setting Up and Testing ONC3/NFS.” | |
Describes special features of the automatic mounters. | Read this chapter if you plan to customize your automatic mounter environment. | |
Contains procedures for implementing ONC3/NFS on server and client systems and verifying their operation. | Use this chapter as a guide to implementing the ONC3/NFS service on your network. | |
Contains procedures for changing the parameters in ONC3/NFS after it is in service. | Use these procedures for routine upkeep of ONC3/NFS. | |
Provides general problem-solving information and check-out procedures. Also describes specific problems that can occur with ONC3/NFS and suggests what you can do to correct them. | Use this chapter to diagnose and correct ONC3/NFS problems. Some of the suggestions in this chapter require an understanding of other network software, such as NIS. | |
Explains error messages that may result from incorrect use of ONC3/NFS. | Read this appendix if you need help resolving an error message that displays. |
To use the setup and maintenance information in this guide, you should have experience in the following areas:
Setting up network services
Assessing the needs of network users
Maintaining hosts databases
Understanding the UNIX® file system structure
Using UNIX editors
To troubleshoot ONC3/NFS, you should be familiar with these concepts:
Theory of network services
Silicon Graphic's network implementation
