Never has something cried out for a cookbook quite as much as Cisco's Internetwork Operating System (IOS). IOS is powerful and flexible, but also confusing and daunting. Most tasks can be accomplished in several different ways. And you don't want to spend precious time figuring out which way is best when you're trying to solve a problem quickly. That's what this cookbook is for. Fortunately, most router configuration tasks can be broken down into several more or less independent steps: you configure an interface, you configure a routing protocol, you set up backup links, you implement packet filters and other access control mechanisms. What you really need is a set of recipes that show you how to perform the most common tasks, so you can quickly come up with a good configuration for your site. And you need to know that these solutions work: you don't want to find yourself implementing a backup link at 2 A.M. because your main link is down and the backup link you set up when you installed the router wasn't quite right. Thoroughly revised and expanded, "Cisco IOS Cookbook, 2nd Edition" adds sections on MPLS, Security, IPv6, and IP Mobility and presents solutions to the most common configuration problems, including: configuring interfaces of many types, from serial to ATM and Frame Relay; configuring all of the common IP routing protocols (RIP, EIGRP, OSPF, and BGP); configuring authentication; configuring other services, including DHCP and NTP; setting up backup links, and using HSRP to configure backup routers; managing the router, including SNMP and other solutions; and using access lists to control the traffic through the router. If you work with Cisco routers, you need a book like this to help you solve problems quickly and effectively. Even if you're experienced, the solutions and extensive explanations will give you new ideas and insights into router configuration. And if you're not experienced - if you've just been given responsibility for managing a network with Cisco routers - this book could be a job-saver.

Fundamentally, computers just deal with numbers. They store letters and other characters by assigning a number for each one. At one time, there were hundreds of different encoding systems for assigning these numbers - but that was before Unicode. Unicode enables a single software product or website to be targeted across multiple platforms, languages and countries without re-engineering. It's no wonder that industry giants like Apple, Hewlett-Packard, IBM and Microsoft have all adopted Unicode. Containing everything you need to understand Unicode, this comprehensive reference from O'Reilly takes you on a detailed guide through the complex character world. For starters, it explains how to identify and classify characters - whether they're common, uncommon, or exotic. It then shows you how to type them, utilize their properties, and process character data in a robust manner. The book is broken up into three distinct parts. The first few chapters provide you with a tutorial presentation of Unicode and character data. It gives you a firm grasp of the terminology you need to reference various components, including character sets, fonts and encodings, glyphs and character repertoires. The middle section offers more detailed information about using Unicode and other character codes. It explains the principles and methods of defining character codes, describes some of the widely used codes, and presents code conversion techniques. It also discusses properties of characters, collation and sorting, line breaking rules and Unicode encodings. The final four chapters cover more advanced material, such as characters in HTML and XHTML. You simply can't afford to be without the nuggets of valuable information detailed in "Unicode Explained".

This concise book contains detailed information about Oracle internals -- information that's not readily available to Oracle customers. It lays a foundation for advanced performance tuning of the Oracle database. Based on Oracle8i release 8.1, the book describes many of the secrets of Oracle's internal services: data structures, algorithms, and undocumented Oracle system statistics. Main topics include: Waits - how Oracle processes communicate via semaphores, and how to use the Oracle wait statistics to identify the source of performance problems. Latches - how they keep multiple processes from inspecting protected data structures at the same time, and how to examine and control latch behavior and statistics. Locks - how they work with latches to protect data structures (locks allow multiple sessions to share resources in some cases), and how locks affect performance. There is also a detailed discussion of instance locks, which are used in parallel server environments. Memory - how Oracle uses memory (e.g., the various elements of the System Global Area), and how Oracle dynamically allocates and manages memory. Oracle8i Internal Services is aimed especially at administrators and developers who need detailed internal information to do advanced performance tuning. The book will expand your repertoire of tuning solutions and troubleshooting techniques by explaining how you can use Oracle's hidden parameters and undocumented system statistics to best advantage. NOTE: The author has collected the scripts he has developed for tuning and analysis into a toolkit (known as APT, for Advanced Performance Tuning). These scripts access the Oracle X$ tables directly and provide information not otherwise available. The scripts are available to readers for free from the O'Reilly web site.

The Internet is a fertile breeding ground for all kinds of scams and schemes, because it's so large and unregulated. Usually it's your credit card number they're after, and they won't stop there. Not just mere annoyances, these scams are real crimes, with real victims. Now, thanks to "Internet Forensics" from O'Reilly, there's something you can do about it. This practical guide to defending against Internet fraud gives you the skills you need to uncover the origins of the spammers, con artists, and identity thieves that plague the Internet. Targeted primarily at the developer community, "Internet Forensics" shows you how to extract the information that lies hidden in every email message, web page, and web server on the Internet. It describes the lengths the bad guys will go to cover their tracks, and offers tricks that you can use to see through their disguises. You'll also gain an understanding for how the Internet functions, and how spammers use these protocols to their devious advantage. This book is organized around the core technologies of the Internet-email, web sites, servers, and browsers. The chapters describe how these are used and abused and show you how information hidden in each of them can be revealed. The short examples illustrate all the major techniques that are discussed. The ethical and legal issues that arise in the uncovering of Internet abuse are also addressed. Not surprisingly, the audience for "Internet Forensics" is boundless. For developers, it's a serious foray into the world of Internet security; for weekend surfers fed up with spam, it's an entertaining and fun guide that lets them play amateur detective from the safe confines of their home or office.

Simple Network Management Protocol (SNMP) provides a "simple" set of operations that allows you to more easily monitor and manage network devices like routers, switches, servers, printers, and more. The information you can monitor with SNMP is wide-ranging--from standard items, like the amount of traffic flowing into an interface, to far more esoteric items, like the air temperature inside a router. In spite of its name, though, SNMP is not especially simple to learn. O'Reilly has answered the call for help with a practical introduction that shows how to install, configure, and manage SNMP. Written for network and system administrators, the book introduces the basics of SNMP and then offers a technical background on how to use it effectively. Essential SNMP explores both commercial and open source packages, and elements like OIDs, MIBs, community strings, and traps are covered in depth. The book contains five new chapters and various updates throughout. Other new topics include: * Expanded coverage of SNMPv1, SNMPv2, and SNMPv3 * Expanded coverage of SNMPc * The concepts behind network management and change management * RRDTool and Cricket * The use of scripts for a variety of tasks * How Java can be used to create SNMP applications * Net-SNMP's Perl module The bulk of the book is devoted to discussing, with real examples, how to use SNMP for system and network administration tasks. Administrators will come away with ideas for writing scripts to help them manage their networks, create managed objects, and extend the operation of SNMP agents. Once demystified, SNMP is much more accessible. If you're looking for a way to more easily manage your network, look no further than Essential SNMP, 2nd Edition.

Do you enjoy writing software, except for the database code? Hibernate:A Developer's Notebook is for you. Database experts may enjoy fiddling with SQL, but you don't have to--the rest of the application is the fun part. And even database experts dread the tedious plumbing and typographical spaghetti needed to put their SQL into a Java program. Hibernate: A Developers Notebook shows you how to use Hibernate to automate persistence: you write natural Java objects and some simple configuration files, and Hibernate automates all the interaction between your objects and the database. You don't even need to know the database is there, and you can change from one database to another simply by changing a few statements in a configuration file. Hibernate: A Developer's Notebook walks you through the ins and outs of using Hibernate, from installation and configuration, to complex associations and composite types. Two chapters explore ways to write sophisticated queries, which you can express either through a pure Java API, or with an SQL-inspired, but object-oriented, query language. Don't let that intimidate you though: one of the biggest surprises in working with Hibernate is that for many of the common real-world application scenarios, you don't need an explicit query at all. If you've needed to add a database backend to your application, don't put it off. It's much more fun than it used to be, and Hibernate: A Developer's Notebook shows you why. Here's what a few reviewers had to say: "I'm sitting on an airplane after finishing Hibernate: A Developer's Notebook. It's rare to find a book on a new Java technology that you can get through on a domestic flight. That this notebook effectively and succinctly tackles object-relational mapping makes it, and Hibernate, even more impressive. Many books in this category would need to be checked luggage. With this book, you travel first class." --Mike Clark "A simple persistence framework deserves a simple book, and this one delivers. The examples are well described and easy to understand, yet sophisticated enough to demonstrate Hibernate in a real-world context. Jim, I'm a new fan." --Bruce Tate About the new Developer's Notebook Series from O'Reilly: Developer's Notebooks are a new book series covering important new tools for software developers. Developer's Notebooks stress example over explanation and practice over theory. They are about learning by doing; by experimenting with tools and discovering what works. "All lab, no lecture," with a thoughtful lab partner to guide the way.
