In the last decade, the Internet has grown from a network that connected a few universities and research centers to a network that links many businesses and households all over the country. That expansion occurred for many reasons, but the technological advance that facilitated this growth was an obscure protocol called PPP.
PPP isn't talked about as much as TCP and IP, but it plays a crucial role in extending networks into remote locations. The Point-to-Point Protocol enables telephone lines and other point-to-point connections to carry Internet traffic. It's the protocol that establishes and maintains the connection between your home and an Internet service provider. This book provides in-depth coverage of PPP for network administrators and others who are involved in the care and maintenance of PPP connections. It provides a thorough introduction to how PPP works, which will help you diagnose and troubleshoot problems. It discusses in detail how to set up dial-in and dial-out PPP on the most important platforms, including Windows, Linux, and Solaris. Whether you're a sophisticated user responsible for your own connection or a network administrator providing dial-up services for hundreds of remote users, you'll find this book an essential addition to your library. Covers:
PPP implementations in Windows 95/98/NT, Solaris, and Linux
Authentication (CHAP, PAP, Microsoft variants, and other techniques)
Andrew Sun's experience with computers dates back to the early 1980s. He is an electrical engineer by training, with an MSEE degree from Stanford University. Andrew has many years of experience in the telecommunications industry and has performed engineering work for emerging broadband ISDN and ATM products. He currently engineers IT infrastructures, and his areas of expertise include networking, firewalls, email with SMTP, DNS, Usenet, Solaris administration, and of course, dial-up remote access.
Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal on the cover of Using and Managing PPP is a turtle, one of many species of terrestrial or aquatic reptile with a bony shell as part of their skeleton protecting the back and underside. All turtles can (to varying degrees) pull the head, neck, tail, and legs into the shell. The dorsal part of the shell is called the carapace; the ventral is the plastron. Turtles have a layer of sensitive skin between the bony plates and horn of the shell; they can feel what touches their shell. The appearance and size of the shell varies greatly with the species. Turtle species range in size from about 11 cm to 2 meters. Aquatic species usually have webbed feet and use their lungs as air or swim bladders, causing air to flow into different parts of the lung.
Turtles have a small but highly developed brain; they are generally somewhat mute and hear poorly, but have an excellent sense of smell. They are capable of learning and have significant memories. Their external sexual characteristics are difficult to distinguish. Some species live for around 100 years; many also have the capability to regenerate or heal severe wounds.
Turtles appear worldwide on land and in oceans with temperate to warm environments. All turtles are hatched from eggs, and all turtle eggs are laid on land. The shape of eggs and number in each batch varies with species. Many species hibernate when the temperatures become too low (or too high). They are slow growers, and their shells display rings showing uneven growth periods, much like the rings of a tree trunk. Mary Anne Weeks Mayo served as production editor for Using and Managing PPP; Mary Anne also served as copyeditor, Sheryl Avruch was the production manager; Ellie Fountain Maden and Marleis Roberts provided quality assurance. Chris Reilley created the illustrations using Macromedia FreeHand 8. Mike Sierra provided FrameMaker technical support. Nancy Crumpton wrote the index and provided production services.
Edie Freedman designed the cover of this book, using a 19th-century engraving from the Dover Pictorial Archive. The cover layout was produced with QuarkXPress 3.32 using the ITC Garamond font. Whenever possible, our books use RepKover(TM), a durable and flexible lay-flat binding. If the page count exceeds RepKover's limit, perfect binding is used.
The inside layout was designed by Nancy Priest and implemented in FrameMaker 5.5 by Mike Sierra. The text and heading fonts are ITC Garamond Light and Garamond Book. This colophon was written by Nancy Kotary.
