TCP/IP and Data Communications Administration Guide

Preface

TCP/IP and Data Communications Administration Guide explains how to set up, maintain, and expand a network running the SolarisTM implementation of the TCP/IP protocol suite. The manual

Who Should Use This Book

TCP/IP and Data Communications Administration Guide contains information for network administrators with a wide range of experience. The text assumes that you are already familiar with the Solaris environment and have administered local machines and peripheral devices such as modems.

If you are setting up a new network, read TCP/IP and Data Communications Administration Guide before going on to the other books in the Solaris 2.5 System Administrator set. If you are administering or expanding an existing network, refer to the specific chapters related to the tasks that you want to perform.

Note -

If you need to set up a brand new network at a site that has never had a Solaris or other UNIX-based network, read Chapter 3, Planning Your Network before installing the Solaris software. This chapter provides important information that supplements the installation tasks in Solaris Advanced Installation Guide.

Reading the chapters in sequence is not required, but each chapter assumes that you are familiar with the contents of previous chapter.

Before You Read This Book

You should be familiar with the information contained in the following books before continuing with the TCP/IP and Data Communications Administration Guide:

How This Book Is Organized

TCP/IP and Data Communications Administration Guide contains the following chapters.

Chapter 1, Overview of Network Administration describes the tasks a network administrator is likely to perform and introduces basic networking concepts.

Chapter 2, TCP/IP Protocol Suite introduces the protocols composing the TCP/IP protocol suite.

Chapter 3, Planning Your Network presents the issues that you need to consider when designing a new network, such as Internet Protocol (IP) addressing, network topology, and so forth.

Chapter 4, Configuring TCP/IP on the Network contains procedures for setting up the machines on the new network.

Chapter 5, Configuring Routers explains how to expand the network through use of routers.

Chapter 6, Troubleshooting TCP/IP explains how to use the tools available for diagnosing and fixing TCP/IP-related problems.

Chapter 7, Understanding PPP introduces the PPP data link protocol that enables you to expand a network through use of modems and phone lines.

Chapter 8, Preparing Your PPP Configuration explains issues that you need to consider when designing a particular PPP configuration.

Chapter 9, Configuring PPP contains procedures for configuring two basic types of PPP links.

Chapter 10, Troubleshooting PPP explains how to diagnose and fix problems related to PPP.

Chapter 11, Tailoring Your PPP Link contains information for setting up more complex PPP links.

Chapter 12, UUCP Databases and Programs explains how to set up the UUCP database files.

Chapter 13, Configuring and Maintaining UUCP explains how to start up UUCP and troubleshoot problems on UUCP links.

Chapter 14, Understanding DHCP introduces the Dynamic Host Configuration Protocol, which allows a host to get an Internet Protocol (IP) address and other Internet configuration parameters without any need for preconfiguration by the system administrator.

Chapter 15, Moving to DHCP describes the differences between DHCP and earlier protocols and how to migrate from these protocols to DHCP.

Chapter 16, Administration of DHCP explains how to set up a network running DHCP, determine a lease time policy, add BOOTP relay agents, and create macros within some of the databases used by DHCP.

Chapter 17, Troubleshooting DHCP describes how to troubleshoot problems you may have while using DHCP.

Appendix A, PCNFSpro Appendix contains troubleshooting techniques that are specific to PCNFSpro running as the Windows client.
