Programmer's Guide to Internet Mail will help you create and manage network applications using powerful Internet mail, directory, and domain name protocols and standards. It succinctly explains from a programmer's perspective not simply the primary Internet mail protocols but also how to use other important network protocols such as LDAP and DNS vital to the creation of message-enabled applications. Readers will learn how these protocols and standards facilitate message submission, delivery and retrieval, support directory lookup, how they interoperate, and how they together create...

This book's comparative approach gives you something more valuable: insight into the decisions you face...

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...

Be more productive and make your life easier. That's what LDAP System Administration is all about.System administrators often spend a great deal of time managing configuration information located on many different machines: usernames, passwords, printer configurations, email client configurations, and network filesystem configurations, to name a few. LDAPv3 provides tools for centralizing all of the configuration information and placing it under your control. Rather than maintaining several administrative databases (NIS, Active Directory, Samba, and NFS configuration files), you can...

Historically, only large companies could afford secure networks, which they created from expensive leased lines. Smaller folks had to make do with the relatively untrusted Internet. Nowadays, even large companies have to go outside their private nets, because so many people telecommute or log in while they're on the road. How do you provide a low-cost, secure electronic network for your organization?The solution is a virtual private network: a collection of technologies that creates secure connections or "tunnels" over regular Internet lines--connections that can be easily used by anybody...

If you've ever been responsible for a network, you know that sinking feeling: your pager has gone off at 2 a.m., the network is broken, and you can't figure out why by using a dial-in connection from home. You drive into the office, dig out your protocol analyzer, and spend the next fourhours trying to put things back together before the staff shows up for work.

When this happens, you often find yourself looking at the low-level guts of the Internet protocols: you're deciphering individual packets, trying to figure out what is (or isn't) happening. Until now, the only real guide to...

Dynamic Host Configuration Protocol (DHCP) is an open standard Internet protocol used to allocate and manage IP addresses dynamically. Before DHCP came along, administrators had to manually configure each host on a network with an IP address, subnet mask, and default gateway. Maintaining the changes and the associated logs took a tremendous amount of time and was prone to error. DHCP uses a client/server model in which the system updates and maintains the network information dynamically. Windows 2000 provides enhanced DHCP client-server support.DHCP for Windows 2000 is...

The HyperText Transfer Protocol, or HTTP, is the backbone of the World Wide Web. HTTP is the language that each web browser (or other web client) uses to communicate with servers around the world. All web programmers, administrators, and application developers need to be familiar with HTTP in order to work effectively.The HTTP Pocket Reference not only provides a solid conceptual foundation of HTTP, it also serves as a quick reference to each of the headers and status codes that comprise an HTTP transaction. The book starts with a tutorial of HTTP, but then explains the client...

For all the work and time invested in using LDAP, not enough time has been spent designing the layout and the logic of directories. End users and system architects often do not give appropriate attention to the deployment of LDAP as a standards-based system with interfacing ability. Thus, many of LDAPs best features--especially OpenLDAP--become unusable.

As a remedy, Deploying OpenLDAP delves into the logic, theories and fundamentals of directories. The text focuses on open standards, rather than proprietary systems, which are expensive and incompatible with other systems. If...

Have you ever tried to figure out why your computer clock is off, or why your emails somehow have the wrong timestamp? Most likely, it's due to an incorrect network time synchronization, which can be reset using the Network Time Protocol. Until now, most network administrators have been too paranoid to work with this, afraid that they would make the problem even worse. However, Expert Network Time Protocol: An Experience in Time with NTP takes the mystery out of time, and shows the network administrator how to regain the upper hand.

This book is a fascinating look into NTP,...

Pro DNS and BIND guides you through the challenging array of features surrounding DNS, with a special focus on BIND, the world's most popular DNS implementation. This book unravels the mysteries of DNS, offering insight into origins, evolution, and key concepts like domain names and zone files. This book focuses on running DNS systems based on BIND 9.3.0 the first stable release that includes support for the latest DNSSEC (DNSSEC.bis) standards and a major functional upgrade from previous BIND 9 releases.

If you administer a DNS system or are thinking about running one, or if...

Running IPv6 explains how to install and operate the IPv6 protocol for Windows XP, Mac OS X, FreeBSD, Red Hat Linux, and Cisco routers. The book also covers DNS and BIND, Zebra, Apache 2, and Sendmail. While IPv4 uses 32-bit addresses, IPv6 addresses are 128 bits long, and allow for more unique addresses. While the adoption of IPv6 won't be immediate, it is necessary.

Running IPv6 compares and contrasts IPv6 to IPv4, and discusses the advantages and disadvantages of each. Because most major software and hardware vendors have adopted IPv6, the focus of this book is to...
