Preface

TCP/IP Network Administration Guide explains how to set up, maintain, and ultimately expand a network running the Solaris implementation of the TCP/IP protocol suite. The manual:

• Defines networking concepts used when working with TCP/IP
• Describes tasks necessary for setting up a new network
• Presents information for maintaining the network
• Explains how to expand the existing network by using routers to create an internetwork
• Describes how to use Point-to-Point Protocol (PPP) to allow remote machines to connect to the network
• Explains how to set up communications with remote machines via the UNIX-to-UNIX Copy Program (UUCP)

Who Should Use This Book

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

If you are setting up a new network, read TCP/IP Network Administration Guide before going on to the other books in the Solaris 2.4 System Administrator AnswerBook. 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 SPARC: Installing Solaris Software.

---

You do not have to read the chapters in sequence, but each chapter assumes that you are familiar with the contents of previous chapter.

How This Book Is Organized

TCP/IP Network 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.
