Linux Networking Cookbook

This book covers both old standbys and newfangled technologies. The old-time stuff includes system administration via serial console, dial-up networking, building an Internet gateway, VLANs, various methods of secure remote access, routing, and traffic control. Newfangled technologies include building your own iPBX with Aster-isk, wireless connectivity, cross-platform remote graphical desktops, hands-free network installation of new systems, single sign-on for mixed Linux and Windows LANs, and IPv6 basics. And, there are chapters on monitoring, alerting, and troubleshooting.

The Internet, and in particular the World Wide Web, have effectively leveled the playing field for businesses and individuals around the world. Do you have a great idea for a web site or a service? Even the more advanced ideas can be relatively easily and cheaply realized without much in the way of initial outlay. You can get shared hosting for a few pennieseach month, and dedicated servers (virtual or otherwise) are getting to the point where they are cheaper now than managed web hosting was just a few years ago. This is all well and good, and being able to start out despite having just a few coins to rub together is certainly a great achievement. But what do you do when you want to take your application to the next step? What if it really starts to take off and you find you have the new Facebook or Amazon on your hands. What do you do then?

La presente es la cuarta edición de este libro. Cada edición ha correspondido a una fase diferente de la manera en que se usaron las redes de computadoras. Cuando apareció la primera edición, en 1980, las redes eran una curiosidad académica. Para la segunda edición, en 1988, las redes ya se usaban en universidades y en grandes empresas. Y en 1996, cuando se editó por tercera vez este libro, las redes de computadoras, en particular Internet, se habían convertido en una realidad cotidiana para millones de personas. El elemento nuevo de la cuarta edición es el rápido crecimiento de las redes inalámbricas en muchas formas. El panorama de las redes ha cambiado radicalmente desde la tercera edición. A mediados de la década de 1990 existían varios tipos de LANs y WANs, junto con pilas de múltiples protocolos. Para el 2003, la única LAN alámbrica de amplio uso tal vez sea Ethernet y prácticamente todas las WANs estarían en Internet. En consecuencia, se habrá eliminado una gran cantidad de material referente a estas antiguas redes. Sin embargo, también abundan los nuevos desarrollos. Lo más importante es el gran aumento de redes inalámbricas, como la 802.11, los ciclos locales inalámbricos, las redes celulares 2G y 3G, Bluetooth, WAP (protocolo de aplicaciones inalámbricas), el i-mode y otros. De acuerdo con esto, se ha agregado una gran cantidad de material a las redes inalámbricas. Otro tema importante y novedoso es la seguridad, por lo que se ha agregado todo un capítulo al respecto

Networking

This book describes co-design approaches, and establishes the links between the QoC (Quality of Control) and QoS (Quality of Service) of the network and computing resources. The methods and tools described in this book take into account, at design level, various parameters and properties that must be satisfied by systems controlled through a network. Among the important network properties examined are the QoC, the dependability of the system, and the feasibility of the real-time scheduling of tasks and messages. Correct exploitation of these approaches allows for efficient design, diagnosis, and implementation of the NCS. This book will be of great interest to researchers and advanced students in automatic control, real-time computing, and networking domains, and to engineers tasked with development of NCS, as well as those working in related network design and engineering fields.

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.

The first edition of this book began in the spring of 1999. At that time, I developed a set of slides and presented an “Introduction to IPv6” course at Bellevue Community College in Bellevue, Washington, to four students. Although the turnout was not what I expected, the time spent learning IPv6, creating the slide presentation, and presenting IPv6 technology to these curious students proved to be an invaluable experience and prepared a firm foundation for future endeavors.

Historically speaking, the first entry-level Cisco certification has been the Cisco Certified Network Associate (CCNA) certification, first offered in 1998. The first three versions of the CCNA certification required that you pass a single exam to become certified. However, over time, the exam kept growing, both in the amount of material covered, and the difficulty level of the questions. So, for the fourth major revision of the exams, announced in 2003, Cisco continued with a single certification (CCNA), but offered two options for the exams to get certified: a single exam option and a two-exam option. The two-exam option allowed people to study

Web-based software projects are increasingly complicated, with a range of different dependencies, requirements, and interlinking components. Swapping between projects, which require different versions of the same software, becomes troublesome. Getting team members up and running on new projects also becomes time-consuming. Vagrant is a powerful tool for creating, managing, and working with virtualized development environments for your projects. By creating a virtual environment for each project, their dependencies and requirements are isolated, and don't interfere; they also don't interfere with software installed on your own machine such as WAMP or MAMP. Colleagues can be up and running on a new project in minutes with a single command. With Vagrant, we can wipe the slate clean if we break our environment, and be back up and running in no time.
