Sendmail or IPv6 Essentials

Sendmail

Author: Bryan Costales

A classic O'Reilly title since 1993, sendmail now covers Versions 8.10 through 8.14 of this email routing program, including dozens of new features, options, and macros. This edition also takes a more nuts-and-bolts approach than its predecessors. It includes both an administration handbook and a reference guide that provide you with clear options for installing, configuring and managing sendmail's latest versions and companion programs. The sendmail program has withstood the test of time because of its ability to solve the mail-routing needs of all sites large or small, complex or simple. But it's also difficult to configure and even more difficult to understand. That's why this book has proven valuable since the dawn of email. With it, you will be able to configure the program to meet any need, so that you never again have to call in a sendmail guru to bail you out. sendmail includes the following sections: Some Basics is especially useful for people new to the program. It covers the basic concepts underlying mail delivery and the roles sendmail plays in that delivery Administration covers all aspects of handling sendmail, from downloading and installing new releases to managing mailing lists and aliases Configuration Reference contains a heavily cross-referenced guide for configuring and tuning sendmail. Every arcane detail of sendmail is listed alphabetically Appendices contain more detail about sendmail than you may ever need This edition also includes new material on SSL and AUTH and a new chapter on Mitlers. If you're interested in what has changed since the last edition, one appendix categorizes the many improvements of sendmail's intervening versions by chapter, completewithreferences to the appropriate sections and page numbers in the book. With sendmail, system administrators, programmers, network engineers, and even inexperienced users will be able to match this challenging but necessary utility to the needs of their network.

IPv6 Essentials

Author: Silvia Hagen

IPv6, the next generation Internet Protocol, has been in the works since the early 90s when the rapid growth of the Internet threatened to exhaust existing IP addresses. Drawing on 20 years of operational experience with the existing protocol (IPv4), the new protocol offers scalability, increased security features, real-time traffic support, and auto-configuration -- so that even a novice user can connect a machine to the Internet. But what does this mean for IT professionals? Having learned all the strengths and weaknesses of the old protocol, will you need to start from scratch with the new?

IPv6 Essentials provides a succinct, in-depth tour of all the new features and functions in IPv6, guiding you through everything you need to know to get started -- including how to configure IPv6 on hosts and routers and which applications currently support IPv6. Aimed at system and network administrators, engineers, network designers, and IT managers, this book will help you plan for, design, and integrate IPv6 into your current IPv4 infrastructure.

Beginning with a short history of IPv6, Silvia Hagen provides an overview of its new functionality and describes some live test and production networks that are using the new protocol. Hagen then shares informative in-depth discussions of the new IPv6 header format and Extension Headers, IPv6 address format, and IPv6 message format. IPv6 Essentials also covers:

• Security in IPv6: concepts, requirements, and solutions -- including the IPSEC framework and security elements available for authentication and encryption
• Quality of Service: covers the types of QoS in IPv6 and how they can be implemented
• Networking: Layer 2 support for IPv6 with sample network designs that show how to integrate IPv6 into your network without interrupting IPv4 services
• Routing protocols and upper layer protocols

Getting started on different operating systems: Sun Solaris, Linux, Windows 2000 and Windows XP

Whether you're ready to start implementing IPv6 today or are planning your strategy for the future, IPv6 Essentials will provide the solid foundation you need to get started.

A well-written, clear, up-to-date guide to understanding IPv6 in-depth. This is a real accomplishment, because computer networking protocols are completely abstract, and translating all of these abstractions into understandable language is a noteworthy feat. The book explains how it all works to a very practical depth, so that the reader will be well-prepared to begin implementation.
