This text provides a comprehensive look at computer networking from the point of view of the network administrator. It guides readers from an entry-level knowledge in computer networks to advanced concepts in Ethernet networks; router configuration; TCP/IP networks; local-, campus-, and wide-area network configuration; network security; optical networks; voice over IP; and industrial networks. Extensive examples on the Windows Server 2003/2008 configuration and system configuration for the Linux operating system are also included. A complete chapter is devoted to protecting and securing a network from potential network attacks. Topics include denial of service attacks, firewalls, intrusion detection, password cracking, packet sniffing, and analyzing unsecured data packets. Other key network security issues, such as configuring router access lists, configuring a virtual private network (VPN) connection, and securing wireless networks, are also covered. Router configuration is examined, ranging from an introduction to router configuration to configuring multiple routing protocols for intranet and Internet data traffic. Routing protocols key to basic network operations are examined, including static, RIP, IGRP, OSPF, EIGRP, and BGP. The discussions on routing protocols are accompanied with in-depth steps for configuring the router to run the protocol, verify operation, and troubleshoot the router.

Key Pedagogical Features

    * NET-CHALLENGE SOFTWARE provides a simulated, hands-on experience in configuring routers and switches. Exercises provided in the text and on the CD challenge readers to undertake certain router/switch network configuration tasks. The software has the look and feel of actually being connected to the router or switch console port.
    * PROTOCOL ANALYZER SOFTWARE included with the text uses the Finisar Surveyor Demo. Examples of using the software to analyze data traffic are included throughout the text.
    * ACCOMPANYING CD-ROM includes the Finisar Surveyor Demo software and captured data traffic used in the text, which enables readers to capture data traffic on their own networks.
    * CONFIGURING, ANALYZING, or TROUBLESHOOTING sections are included with each chapter to guide the reader through advanced techniques in networking.
    * OBJECTIVES and INTRODUCTION at the beginning of each chapter clearly outline specific goals for the reader.
    * EXTENSIVE PROBLEM SETS, SUMMARIES, and QUESTIONS AND PROBLEMS (including Critical Thinking questions) are found at the end of each chapter.
    * KEY TERMS and their definitions are highlighted in the margins to foster inquisitiveness and ensure retention.

Originally designed to sabotage or annihilate websites, computerized “Bots” are increasingly used in mass spamming events, fraud, extortion, identity theft, and software theft. Focusing on the malicious use of bots and bot herder means and motivations, Malicious Bots provides a much needed a resource for understanding the scope, sophistication, and criminal uses of bots and how to more proactively protect against them. Accessibly written, but with sufficient technical detail, the book introduces botnet threats and how they function and examines the top bot attacks against financial and government networks over the last four years to reveal the who, how, and why behind them.

When Flash Player 9 released in June 2006, it introduced the new scripting language, ActionScript 3, which has already taken hold in the Adobe Flex application development community. ActionScript 3 provides not only a significant enhancement in performance, but also a more robust programming model that lends itself to complex Rich Internet Application development. For web designers and developers who need to make the move to ActionScript 3 from the previous version, ActionScript 2, the learning curve has proven to be significant. In this essential and timely guide, ActionScript expert Kris Hadlock speaks squarely to the many thousands of ActionScript 2 users who need to make the leap right away. The ActionScript Migration Guide covers all of the major changes in ActionScript from version 2 to 3. The book explains the most important and fundamental changes in ActionScript drawing comparisons between the two languages both visually and contextually. With a comprehensive index and robust table of contents designers and developers will easily be able to locate the old an/or new codes with side-by-side comparisons of how to program both and the explanation of the concepts behind them.

Python: Create-Modify-Reuse is designed for all levels of Python developers interested in a practical, hands-on way of learning Python development. This book is designed to show you how to use Python (in combination with the raw processing power of your computer) to accomplish real-world tasks in a more efficient way. Don’t look for an exhaustive description of the Python language––you won’t find it. The book’s main purpose is not to thoroughly cover the Python language, but rather to show how you can use Python to create robust, real-world applications.

In this respect, the goal is similar to foreign-language books that identify themselves as “conversational,” focusing on the vocabulary and concepts that people will need the most. Likewise, I focus specifically on the Python knowledge needed to accomplish practical, specific tasks. Along the way, you will learn to create useful, efficient scripts that are easy to maintain and enhance.

This book is for developers with some experience with Python who want to explore how to develop full-blown applications. It is also for developers with experience in other languages who want to learn Python by building robust applications. It is well-suited for developers who like to “learn by doing,” rather than exploring a language feature by feature. To get the most out of the book, you should understand basic programming principles.

Because this book is project-based, you can approach it in numerous ways. You can, of course, read it from cover to cover. Chapters 2 through 8 each cover a different project, so the chapters are independent of each other. However, because each chapter project is covered individually, there may be some overlap of information. I also sometimes refer to explanations of particular topics covered in previous chapters. This will help to reinforce important concepts.

The end of the book contains two appendixes. The first one is a listing of Python resources you can check out for more information. The second one will help you with installing additional components used in some of the examples.

This book starts with a basic overview of the Python language, designed for those familiar with other languages but new to Python. It is followed by several chapters, each of which describes a complete project that can be used as-is or modified and extended to suit your particular purposes. You’ll find applications that access databases, take advantage of web technologies, and facilitate network communications, to name a few. In addition, and more important than the technologies you will be introduced to, you will learn how to use Python to solve real challenges. Following these chapters are two chapters that cover accessing operating system resources and debugging and testing, respectively.

Each project chapter contains complete instructions describing how to install and use the application, so you can actually see the program run as you learn how to construct and use it, including how the project was designed and prototyped. This book is intended to be both a reference guide and a learning aid, teaching you how to build solutions with Python and providing reference information on a wide variety of Python programming concepts.

It is hoped that this book will help you have fun with Python and build useful applications, and—unlike my experience with building a deck—without sore thumbs.

This book is framed around the code itself. This is because developers are typically looking for how to do something; and, as with many activities, you learn how to do something by watching how others do and trying it yourself. If you want to know how a for loop works, you’ll find for loops in my code, but that’s not the thrust of the book. Instead, this book shows you how to do things: how to build a content management system, how to build a test management system, how to set up a system for tracking customer follow-up, and so on. Along the way, you’ll learn how to communicate with a SQL database, how to act as a web server or communicate with one, how to access operating system services, and more.
