    Abstract: The key to mastering any Unix system, especially Linux and Mac OS X, is a thorough knowledge of shell scripting. Scripting is a way to harness and customize the power of any Unix system, and it's an essential skill for any Unix users, including system administrators and professional OS X developers. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards. bash Cookbook teaches shell scripting the way Unix masters practice the craft. It presents a variety of recipes and tricks for all levels of shell programmers so that anyone can become a proficient user of the most common Unix shell -- the bash shell -- and cygwin or other popular Unix emulation packages. Packed full of useful scripts, along with examples that explain how to create better scripts, this new cookbook gives professionals and power users everything they need to automate routine tasks and enable them to truly manage their systems -- rather than have their systems manage them.

    Abstract: The rise of network-based, automated services in the past decade has definitely changed the way businesses operate, but not always for the better. Offering services, conducting transactions and moving data on the Web opens new opportunities, but many CTOs and CIOs are more concerned with the risks. Like the rulers of medieval cities, they've adopted a siege mentality, building walls to keep the bad guys out. It makes for a secure perimeter, but hampers the flow of commerce. Fortunately, some corporations are beginning to rethink how they provide security, so that interactions with customers, employees, partners, and suppliers will be richer and more flexible. Digital Identity explains how to go about it. This book details an important concept known as "identity management architecture" (IMA): a method to provide ample protection while giving good guys access to vital information and systems. In today's service-oriented economy, digital identity is everything. IMA is a coherent, enterprise-wide set of standards, policies, certifications and management activities that enable companies like yours to manage digital identity effectively--not just as a security check, but as a way to extend services and pinpoint the needs of customers. Author Phil Windley likens IMA to good city planning. Cities define uses and design standards to ensure that buildings and city services are consistent and workable. Within that context, individual buildings--or system architectures--function as part of the overall plan. With Windley's experience as VP of product development for ExciteHome.com and CIO of Governor Michael Leavitt's administration in Utah, he provides a rich, real-world view of the concepts, issues, and technologies behind identity management architecture. How does digital identity increase business opportunity? Windley's favorite example is the ATM machine. With ATMs, banks can now offer around-the-clock service, serve more customers simultaneously, and do it in a variety of new locations. This fascinating book shows CIOs, other IT professionals, product managers, and programmers how security planning can support business goals and opportunities, rather than holding them at bay.

    Abstract: If you're one of the many Unix developers drawn to Mac OS X for its Unix core, you'll find yourself in surprisingly unfamiliar territory. Unix and Mac OS X are kissing cousins, but there are enough pitfalls and minefields in going from one to another that even a Unix guru can stumble, and most guides to Mac OS X are written for Mac aficionados. For a Unix developer, approaching Tiger from the Mac side is a bit like learning Russian by reading the Russian side of a Russian-English dictionary. Fortunately, O'Reilly has been the Unix authority for over 25 years, and in Mac OS X Tiger for Unix Geeks , that depth of understanding shows.This is the book for Mac command-line fans. Completely revised and updated to cover Mac OS X Tiger, this new edition helps you quickly and painlessly get acclimated with Tiger's familiar-yet foreign-Unix environment. Topics include: Using the Terminal and understanding how it differs from an xterm Using Directory Services, Open Directory (LDAP), and NetInfo Compiling code with GCC 3 Library linking and porting Unix software Creating and installing packages with Fink Using DarwinPorts Search through metadata with Spotlight's command-line utilities Building the Darwin kernel Running X Windows on top of Mac OS X, or better yet, run Mac OS X on a Windows machine with PearPC! Mac OS X Tiger for Unix Geeks is the ideal survival guide for taming the Unix side of Tiger. If you're a Unix geek with an interest in Mac OS X, you'll find this clear, concise book invaluable.

    Abstract: Are you serious about network security? Then check out SSH, the Secure Shell, which provides key-based authentication and transparent encryption for your network connections. It's reliable, robust, and reasonably easy to use, and both free and commercial implementations are widely available for most operating systems. While it doesn't solve every privacy and security problem, SSH eliminates several of them very effectively.Everything you want to know about SSH is in our second edition of SSH, The Secure Shell: The Definitive Guide . This updated book thoroughly covers the latest SSH-2 protocol for system administrators and end users interested in using this increasingly popular TCP/IP-based solution.How does it work? Whenever data is sent to the network, SSH automatically encrypts it. When data reaches its intended recipient, SSH decrypts it. The result is "transparent" encryption-users can work normally, unaware that their communications are already encrypted. SSH supports secure file transfer between computers, secure remote logins, and a unique "tunneling" capability that adds encryption to otherwise insecure network applications. With SSH, users can freely navigate the Internet, and system administrators can secure their networks or perform remote administration.Written for a wide, technical audience, SSH, The Secure Shell: The Definitive Guide covers several implementations of SSH for different operating systems and computing environments. Whether you're an individual running Linux machines at home, a corporate network administrator with thousands of users, or a PC/Mac owner who just wants a secure way to telnet or transfer files between machines, our indispensable guide has you covered. It starts with simple installation and use of SSH, and works its way to in-depth case studies on large, sensitive computer networks.No matter where or how you're shipping information, SSH, The Secure Shell: The Definitive Guide will show you how to do it securely.

    Abstract: System developers have used modeling languages for decades to specify, visualize, construct, and document systems. The Unified Modeling Language (UML) is one of those languages. UML makes it possible for team members to collaborate by providing a common language that applies to a multitude of different systems. Essentially, it enables you to communicate solutions in a consistent, tool-supported language.Today, UML has become the standard method for modeling software systems, which means you're probably confronting this rich and expressive language more than ever before. And even though you may not write UML diagrams yourself, you'll still need to interpret diagrams written by others. UML 2.0 in a Nutshell from O'Reilly feels your pain. It's been crafted for professionals like you who must read, create, and understand system artifacts expressed using UML. Furthermore, it's been fully revised to cover version 2.0 of the language.This comprehensive new edition not only provides a quick-reference to all UML 2.0 diagram types, it also explains key concepts in a way that appeals to readers already familiar with UML or object-oriented programming concepts.Topics include: The role and value of UML in projects The object-oriented paradigm and its relation to the UML An integrated approach to UML diagrams Class and Object, Use Case, Sequence, Collaboration, Statechart, Activity, Component, and Deployment Diagrams Extension Mechanisms The Object Constraint Language (OCL) If you're new to UML, a tutorial with realistic examples has even been included to help you quickly familiarize yourself with the system.

    Abstract: If you're an advanced security professional, then you know that the battle to protect online privacy continues to rage on. Security chat rooms, especially, are resounding with calls for vendors to take more responsibility to release products that are more secure. In fact, with all the information and code that is passed on a daily basis, it's a fight that may never end. Fortunately, there are a number of open source security tools that give you a leg up in the battle.Often a security tool does exactly what you want, right out of the box. More frequently, you need to customize the tool to fit the needs of your network structure. Network Security Tools shows experienced administrators how to modify, customize, and extend popular open source security tools such as Nikto, Ettercap, and Nessus.This concise, high-end guide discusses the common customizations and extensions for these tools, then shows you how to write even more specialized attack and penetration reviews that are suited to your unique network environment. It also explains how tools like port scanners, packet injectors, network sniffers, and web assessment tools function.Some of the topics covered include: Writing your own network sniffers and packet injection tools Writing plugins for Nessus, Ettercap, and Nikto Developing exploits for Metasploit Code analysis for web applications Writing kernel modules for security applications, and understanding rootkits While many books on security are either tediously academic or overly sensational, Network Security Tools takes an even-handed and accessible approach that will let you quickly review the problem and implement new, practical solutions--without reinventing the wheel. In an age when security is critical, Network Security Tools is the resource you want at your side when locking down your network.

    Abstract: If you are a network administrator, you're under a lot of pressure to ensure that mission-critical systems are completely safe from malicious code, buffer overflows, stealth port scans, SMB probes, OS fingerprinting attempts, CGI attacks, and other network intruders. Designing a reliable way to detect intruders before they get in is an essential--but often overwhelming--challenge. Snort, the defacto open source standard of intrusion detection tools, is capable of performing real-time traffic analysis and packet logging on IP network. It can perform protocol analysis, content searching, and matching. Snort can save countless headaches; the new Snort Cookbook will save countless hours of sifting through dubious online advice or wordy tutorials in order to leverage the full power of SNORT.Each recipe in the popular and practical problem-solution-discussion O'Reilly cookbook format contains a clear and thorough description of the problem, a concise but complete discussion of a solution, and real-world examples that illustrate that solution. The Snort Cookbook covers important issues that sys admins and security pros will us everyday, such as: installation optimization logging alerting rules and signatures detecting viruses countermeasures detecting common attacks administration honeypots log analysis But the Snort Cookbook offers far more than quick cut-and-paste solutions to frustrating security issues. Those who learn best in the trenches--and don't have the hours to spare to pore over tutorials or troll online for best-practice snippets of advice--will find that the solutions offered in this ultimate Snort sourcebook not only solve immediate problems quickly, but also showcase the best tips and tricks they need to master be security gurus--and still have a life.

    Abstract: "The book you are about to read will arm you with the knowledge you need to defend your network from attackers-both the obvious and the not so obvious.... If you are new to network security, don't put this book back on the shelf! This is a great book for beginners and I wish I had access to it many years ago. If you've learned the basics of TCP/IP protocols and run an open source or commercial IDS, you may be asking 'What's next?' If so, this book is for you." -Ron Gula, founder and CTO, Tenable Network Security, from the Foreword "Richard Bejtlich has a good perspective on Internet security-one that is orderly and practical at the same time. He keeps readers grounded and addresses the fundamentals in an accessible way." -Marcus Ranum, TruSecure "This book is not about security or network monitoring: It's about both, and in reality these are two aspects of the same problem. You can easily find people who are security experts or network monitors, but this book explains how to master both topics." -Luca Deri, ntop.org "This book will enable security professionals of all skill sets to improve their understanding of what it takes to set up, maintain, and utilize a successful network intrusion detection strategy." -Kirby Kuehl, Cisco Systems Every network can be compromised. There are too many systems, offering too many services, running too many flawed applications. No amount of careful coding, patch management, or access control can keep out every attacker. If prevention eventually fails, how do you prepare for the intrusions that will eventually happen? Network security monitoring (NSM) equips security staff to deal with the inevitable consequences of too few resources and too many responsibilities. NSM collects the data needed to generate better assessment, detection, and response processes-resulting in decreased impact from unauthorized activities. In The Tao of Network Security Monitoring , Richard Bejtlich explores the products, people, and processes that implement the NSM model. By focusing on case studies and the application of open source tools, he helps you gain hands-on knowledge of how to better defend networks and how to mitigate damage from security incidents. Inside, you will find in-depth information on the following areas. The NSM operational framework and deployment considerations. How to use a variety of open-source tools-including Sguil, Argus, and Ethereal-to mine network traffic for full content, session, statistical, and ale...

    Abstract: O'Reilly's bestselling book on Linux's bash shell is at it again. Now that Linux is an established player both as a server and on the desktop Learning the bash Shell has been updated and refreshed to account for all the latest changes. Indeed, this third edition serves as the most valuable guide yet to the bash shell.As any good programmer knows, the first thing users of the Linux operating system come face to face with is the shell the UNIX term for a user interface to the system. In other words, it's what lets you communicate with the computer via the keyboard and display. Mastering the bash shell might sound fairly simple but it isn't. In truth, there are many complexities that need careful explanation, which is just what Learning the bash Shell provides.If you are new to shell programming, the book provides an excellent introduction, covering everything from the most basic to the most advanced features. And if you've been writing shell scripts for years, it offers a great way to find out what the new shell offers. Learning the bash Shell is also full of practical examples of shell commands and programs that will make everyday use of Linux that much easier. With this book, programmers will learn: How to install bash as your login shell The basics of interactive shell use, including UNIX file and directory structures, standard I/O, and background jobs Command line editing, history substitution, and key bindings How to customize your shell environment without programming The nuts and bolts of basic shell programming, flow control structures, command-line options and typed variables Process handling, from job control to processes, coroutines and subshells Debugging techniques, such as trace and verbose modes Techniques for implementing system-wide shell customization and features related to system security

    Abstract: Stories about hacking, stolen credit card numbers, computer viruses, and identity theft are all around us, but what do they really mean to us? The goal of this book, quite simply, is to help educate people on the issues with high-tech crimes. High-Tech Crimes Revealed: Cyberwar Stories from the Digital Front demystifies the risks and realities of high-tech crimes. Demystifying these crimes and raising the awareness of users of technology will make people smarter and safer, and that will make all of us safer in the long run. Steven Branigan shares the inside details of real cases he worked on in his various roles in law-enforcement, information technology, and security. The result is a comprehensive, accessible look at how digital crimes are discovered, what techniques the criminals use and why, and (in some cases) how they can be brought to justice. Inside, you'll find extensive information on Actual hacker investigations, including the harm caused and how the criminals were tracked and caught The ins and outs of identity theft, a rapidly growing crime with potential for serious damage Using the criminology and psychology of hackers to detect and deter attacks The risks associated with various technologies Do's and don'ts for high-tech criminal investigations This easily understandable book will take you beyond hearing about high-tech crimes to actually understanding how and why they happen-and what can be done to protect yourself. "Most books on this topic impart knowledge in the form of techniques and methods. This book differs in that it imparts Steven Branigan's experience in the field, and real case studies in which problems are framed and effective solutions are crafted. In this respect this book imparts not only knowledge, but Steve's experience and wisdom as well." -Mike Tarrani, Independent Consultant "Steven Branigan provides a gripping account of what's involved in investigating computer crime. I strongly recommend this book to any security practitioner or anyone with an interest in computer security." -Michael Nickle, Lead Consultant, VeriSign "Being on the inside of several high-tech busts has given Steven Branigan the ability to make this book intriguing enough to keep high-tech types interested, while also doing a superb job of demystifying these real-life cases in a way that anyone can read and enjoy." -David Kensiski, Director of Operations, InfiniRoute Networks "The modern high-tech industry brought new things to our lives.

    Abstract: In OBJECT THINKING, esteemed object technologist David West contends that the mindset makes the programmer-not the tools and techniques. Delving into the history, philosophy, and even politics of object-oriented programming, West reveals how the best programmers rely on analysis and conceptualization-on thinking-rather than formal process and methods. Both provocative and pragmatic, this book gives form to what's primarily been an oral tradition among the field's revolutionary thinkers-and it illustrates specific object-behavior practices that you can adopt for true object design and superior results. Gain an in-depth understanding of: Prerequisites and principles of object thinking. Object knowledge implicit in eXtreme Programming (XP) and Agile software development. Object conceptualization and modeling. Metaphors, vocabulary, and design for object development. Learn viable techniques for: Decomposing complex domains in terms of objects. Identifying object relationships, interactions, and constraints. Relating object behavior to internal structure and implementation design. Incorporating object thinking into XP and Agile practice.

    Abstract: Intrusion detection is not for the faint at heart. But, if you are a network administrator chances are you're under increasing pressure to ensure that mission-critical systems are safe--in fact impenetrable--from malicious code, buffer overflows, stealth port scans, SMB probes, OS fingerprinting attempts, CGI attacks, and other network intruders.Designing a reliable way to detect intruders before they get in is a vital but daunting challenge. Because of this, a plethora of complex, sophisticated, and pricy software solutions are now available. In terms of raw power and features, SNORT, the most commonly used Open Source Intrusion Detection System, (IDS) has begun to eclipse many expensive proprietary IDSes. In terms of documentation or ease of use, however, SNORT can seem overwhelming. Which output plugin to use? How do you to email alerts to yourself? Most importantly, how do you sort through the immense amount of information Snort makes available to you?Many intrusion detection books are long on theory but short on specifics and practical examples. Not Managing Security with Snort and IDS Tools . This new book is a thorough, exceptionally practical guide to managing network security using Snort 2.1 (the latest release) and dozens of other high-quality open source other open source intrusion detection programs. Managing Security with Snort and IDS Tools covers reliable methods for detecting network intruders, from using simple packet sniffers to more sophisticated IDS (Intrusion Detection Systems) applications and the GUI interfaces for managing them. A comprehensive but concise guide for monitoring illegal entry attempts, this invaluable new book explains how to shut down and secure workstations, servers, firewalls, routers, sensors and other network devices.Step-by-step instructions are provided to quickly get up and running with Snort. Each chapter includes links for the programs discussed, and additional links at the end of the book give administrators access to numerous web sites for additional information and instructional material that will satisfy even the most serious security enthusiasts. Managing Security with Snort and IDS Tools maps out a proactive--and effective--approach to keeping your systems safe from attack.

    Abstract: When Object Oriented programming (OO) first appeared, it was a revelation. OO gave developers the ability to create software that was more flexible and robust, but as time went on and applications became more sophisticated, too, certain areas of "traditional" OO architectures were found wanting. Aspect-oriented programming (AOP) addresses those issues by extending the OO approach even further.Many developers are interested in AOP--especially in AspectJ, the open source extension of the Java programming language that explicitly supports the AOP approach. Yet, although AspectJ is included with Eclipse, the increasingly popular open source IDE for Java, finding a practical and non-theoretical way to learn this language and other AOP tools and techniques has been a real problem.Until now. The AspectJ Cookbook offers a hands-on solution--in fact, several--with a wide variety of code recipes for solving day-to-day design and coding problems using AOP's unique approach.AOP allows the global properties of a program to determine how it's compiled into an executable program. Before AOP, important program design decisions were difficult to capture in actual code. Instead, the implementation of those design decisions--known as "aspects"--were scattered throughout, resulting in "tangled" code that was hard to develop and maintain. AOP has been compared to the manufacturing of cloth, in which threads are automatically interwoven. Without AOP, programmers must stitch the threads by hand.The AspectJ Cookbook shows readers why, and how, common Java development problems can be solved by using AOP techniques. With our popular problem-solution-discussion format, the book presents real world examples to demonstrate that AOP is more than just a concept; it's a development process that will benefit users in an immediate and visible manner.If you're interested in how AOP is changing the way software is developed, and how you can use AspectJ to make code more modular, easier to develop, maintain, evolve and deploy, this is the book that really delivers.

    Abstract: "A refreshingly new approach toward improving use-case modeling by fortifying it with aspect orientation." - Ramnivas Laddad, author of AspectJ in Action "Since the 1980s, use cases have been a way to bring users into software design, but translating use cases into software has been an art, at best, because user goods often don't respect code boundaries. Now that aspect-oriented programming (AOP) can express crosscutting concerns directly in code, the man who developed use cases has proposed step-by-step methods for recognizing crosscutting concerns in use cases and writing the code in separate modules. If these methods are at all fruitful in your design and development practice, they will make a big difference in software quality for developers and users alike. - Wes Isberg, AspectJ team member "This book not only provides ideas and examples of what aspect-oriented software development is but how it can be utilized in a real development project." - MichaelWard, ThoughtWorks, Inc. "No system has ever been designed from scratch perfectly; every system is composed of features layered in top of features that accumulate over time. Conventional design techniques do not handle this well, and over time the integrity of most systems degrades as a result. For the first time, here is a set of techniques that facilitates composition of behavior that not only allows systems to be defined in terms of layered functionality but composition is at the very heart of the approach. This book is an important advance in modern methodology and is certain to influence the direction of software engineering in the next decade, just as Object-Oriented Software Engineering influenced the last." - Kurt Bittner, IBM Corporation "Use cases are an excellent means to capture system requirements and drive a user-centric view of system development and testing. This book offers a comprehensive guide on explicit use-case-driven development from early requirements modeling to design and implementation. It provides a simple yet rich set of guidelines to realize use-case models using aspect-oriented design and programming. It is a valuable resource to researchers and practitioners alike." - Dr. Awais Rashid, Lancaster University, U.K., and author of Aspect-Oriented Database Systems "AOSD is important technology that will help developers produce better systems. Unfortunately, it has not been obvious how to integrate AOSD across a project's lifecycle. This book shatters that ba...

    Abstract: "Ajay and Scott take an interesting approach in filling Defend I.T. with case studies and using them to demonstrate important security principles. This approach works well and is particularly valuable in the security space, where companies and consultants are often hesitant to discuss true security incidents for potential embarrassment and confidentiality reasons. Defend I.T. is full of engaging stories and is a good read." --Fyodor, author of the Nmap Security Scanner and Insecure.Org " Defend I.T. answers reader demand for scenario-driven examples. Security professionals will be able to look at these case studies and relate them to their own experiences. That sets this book apart." --Lance Hayden, Cisco Systems "This is an exciting book! It's like reading several mysteries at once from different viewpoints, with the added benefit of learning forensic procedures along the way. Readers will benefit from the procedures, and the entertaining presentation is a real plus." --Elizabeth Zinkann, Equilink Consulting The battle between IT professionals and those who use the Internet for destructive purposes is raging--and there is no end in sight. Reports of computer crime and incidents from the CERT Coordination Center at Carnegie Mellon University more than double each year and are expected to rise. Meanwhile, viruses and worms continue to take down organizations for days. Defend I.T.: Security by Example draws on detailed war stories to identify what was done right and what was done wrong in actual computer-security attacks, giving you the opportunity to benefit from real experiences. Approaches to securing systems and networks vary widely from industry to industry and organization to organization. By examining a variety of real-life incidents companies are too embarrassed to publicly share, the authors explain what could have been done differently to avoid the losses incurred--whether creating a different process for incident response or having better security countermeasures in place to begin with. Inside, you'll find in-depth case studies in a variety of categories: Basic Hacking: Blackhat bootcamp, including mapping a network, exploiting vulnerable architecture, and launching denial-of-service attacks Current Methods: The latest in malicious deeds, including attacks on wireless networks, viruses and worms, and compromised Web servers Additional Items on the Plate: Often overlooked security measures such as developing a security policy, intrusio...

Raymond brings together for the first time the philosophy, design patterns, tools, culture, and traditions that make UNIX home to the world's best and most innovative software, and shows how these are carried forward in Linux and today's open-source movement. Using examples from leading open-source projects, he shows UNIX and Linux programmers how to apply this wisdom in building software that's more elegant, more portable, more reusable, and longer-lived. Raymond incorporates commentary from thirteen UNIX pioneers: Ken Thompson , the inventor of UNIX. Ken Arnold , part of the group that created the 4BSD UNIX releases and co-author of The Java Programming Language . Steven M. Bellovin , co-creator of Usenet and co-author of Firewalls and Internet Security . Stuart Feldman , a member of the Bell Labs UNIX development group and the author of make and f77 .

Whether your background is security or networking, you can use this book to learn how to bridge the gap between a highly available, efficient network and one that strives to maximize security. The included secure network design techniques focus on making network and security technologies work together as a unified system rather than as isolated systems deployed in an ad-hoc way. Beginning where other security books leave off, Network Security Architectures shows you how the various technologies that make up a security system can be used together to improve your network's security. The technologies and best practices you'll find within are not restricted to a single vendor but broadly apply to virtually any network system. This book discusses the whys and hows of security, from threats and counter measures to how to set up your security policy to mesh with your network architecture. After learning detailed security best practices covering everything from Layer 2 security to e-commerce design, you'll see how to apply the best practices to your network and learn to design your own security system to incorporate the requirements of your security policy. You'll review detailed desig...

    Abstract: In the world of Unix operating systems, the various BSDs come with a long heritage of high-quality software and well-designed solutions, making them a favorite OS of a wide range of users. Among budget-minded users who adopted BSD early on to developers of some of today's largest Internet sites, the popularity of BSD systems continues to grow. If you use the BSD operating system, then you know that the secret of its success is not just in its price tag: practical, reliable, extraordinarily stable and flexible, BSD also offers plenty of fertile ground for creative, time-saving tweaks and tricks, and yes, even the chance to have some fun."Fun?" you ask. Perhaps "fun" wasn't covered in the manual that taught you to install BSD and administer it effectively. But BSD Hacks , the latest in O'Reilly's popular Hacks series, offers a unique set of practical tips, tricks, tools--and even fun--for administrators and power users of BSD systems. BSD Hacks takes a creative approach to saving time and getting more done, with fewer resources. You'll take advantage of the tools and concepts that make the world's top Unix users more productive. Rather than spending hours with a dry technical document learning what switches go with a command, you'll learn concrete, practical uses for that command.The book begins with hacks to customize the user environment. You'll learn how to be more productive in the command line, timesaving tips for setting user-defaults, how to automate long commands, and save long sessions for later review. Other hacks in the book are grouped in the following areas: Customizing the User Environment Dealing with Files and Filesystems The Boot and Login Environments Backing Up Networking Hacks Securing the System Going Beyond the Basics Keeping Up-to-Date Grokking BSD If you want more than your average BSD user--you want to explore and experiment, unearth shortcuts, create useful tools, and come up with fun things to try on your own-- BSD Hacks is a must-have. This book will turn regular users into power users and system administrators into super system administrators.

    Abstract: If you're using PHP 4, then chances are good that an upgrade to PHP 5 is in your future. The more you've heard about the exciting new features in PHP 5, the sooner that upgrade is probably going to be. Although an in-depth, soup-to-nuts reference guide to the language is good to have on hand, it's not the book an experienced PHP programmer needs to get started with the latest release. What you need is a lean and focused guide that answers your most pressing questions: what's new with the technology, what's different, and how do I make the best use of it? In other words, you need a copy of Upgrading to PHP 5 . This book is targeted toward PHP developers who are already familiar with PHP 4. Rather than serve as a definitive guide to the entire language, the book zeroes in on PHP 5's new features, and covers these features definitively. You'll find a concise appraisal of the differences between PHP 4 and PHP 5, a detailed look at what's new in this latest version, and you'll see how PHP 5 improves on PHP 4 code. See PHP 4 and PHP 5 code side-by-side, to learn how the new features make it easier to solve common PHP problems. Each new feature is shown in code, helping you understand why it's there, when to use it, and how it's better than PHP 4. Short, sample programs are included throughout the book. Topics covered in Upgrading to PHP 5 include: The new set of robust object-oriented programming features An improved MySQL extension, supporting MySQL 4.1, prepared statements, and bound parameters Completely rewritten support for XML: DOM, XSLT, SAX, and SimpleXML Easy web services with SOAP SQLite, an embedded database library bundled with PHP 5 Cleaner error handling with exceptions Other new language features, such as iterators, streams, and more. Upgrading to PHP 5 won't make you wade through information you've covered before. Written by Adam Trachtenberg, coauthor of the popular PHP Cookbook , this book will take you straight into the heart of all that's new in PHP 5. By the time you've finished, you'll know PHP 5 in practice as well as in theory.

    Abstract: A new edition of this title is available, ISBN-10: 0321566157 ISBN-13: 9780321566157 Programming in Objective-C is a concise, carefully written tutorial on the basics of Objective-C and object-oriented programming. The book makes no assumption about prior experience with object-oriented programming languages or with the C language (upon which Objective-C is based). And because of this, both novice and experienced programmers alike can use this book to quickly and effectively learn the fundamentals of Objective-C. Readers can also learn the concepts of object-oriented programming without having to first learn all of the intricacies of the underlying procedural language (C). This approach, combined with many small program examples and exercises at the end of each chapter, makes it ideally suited for either classroom use or self-study. Growth is expected in this language. At the January 2003 MacWorld, it was announced that there are 5 million Mac OS X users and each of their boxes ships with Objective-C built in.

    Abstract: To the uninitiated, the title may seem like an oxymoron: after all, aren't hacks what network security is supposed to prevent? But if you're network administrator, this book's title not only makes sense; it makes a lot of sense. You know that a busy administrator needs a hatful of devilishly effective security hacks to keep your 12-hour days from becoming all-nighters. Network Security Hacks is not a long-winded treatise on security theory. Instead, this information packed little book provides 100 quick, practical, and clever things to do to help make your Linux, UNIX, or Windows networks more secure today. This compendium of security hacks doesn't just cover securing TCP/IP-based services, but also provides intelligent host-based security techniques. Loaded with concise but powerful examples of applied encryption, intrusion detection, logging, trending, and incident response, Network Security Hacks will demonstrate effective methods for defending your servers and networks from a variety of devious and subtle attacks. Network Security Hacks show how to detect the presence (and track every keystroke) of network intruders, methods for protecting your network and data using strong encryption, and even techniques for laying traps for would-be system crackers. Important security tools are presented, as well as clever methods for using them to reveal real, timely, useful information about what is happening on your network. O'Reilly's Hacks Series reclaims the term "hacking" for the good guys--innovators who use their ingenuity to solve interesting problems, explore and experiment, unearth shortcuts, and create useful tools. Network Security Hacks lives up to reputation the Hacks series has earned by providing the "roll-up-your sleeves and get-it-done" hacks that most network security tomes don't offer. Every hack can be read in just a few minutes but will save hours of searching for the right answer. Using just one of these amazing hacks will make this slim book's price seem like a remarkable deal. The other 99 make Network Security Hacks absolutely invaluable.

    Abstract: When it comes to network security, many users and administrators are running scared, and justifiably so. The sophistication of attacks against computer systems increases with each new Internet worm.What's the worst an attacker can do to you? You'd better find out, right? That's what Security Warrior teaches you. Based on the principle that the only way to defend yourself is to understand your attacker in depth, Security Warrior reveals how your systems can be attacked. Covering everything from reverse engineering to SQL attacks, and including topics like social engineering, antiforensics, and common attacks against UNIX and Windows systems, this book teaches you to know your enemy and how to be prepared to do battle. Security Warrior places particular emphasis on reverse engineering. RE is a fundamental skill for the administrator, who must be aware of all kinds of malware that can be installed on his machines -- trojaned binaries, "spyware" that looks innocuous but that sends private data back to its creator, and more. This is the only book to discuss reverse engineering for Linux or Windows CE. It's also the only book that shows you how SQL injection works, enabling you to inspect your database and web applications for vulnerability. Security Warrior is the most comprehensive and up-to-date book covering the art of computer war: attacks against computer systems and their defenses. It's often scary, and never comforting. If you're on the front lines, defending your site against attackers, you need this book. On your shelf--and in your hands.

    Abstract: "Eric Evans has written a fantastic book on how you can make the design of your software match your mental model of the problem domain you are addressing. "His book is very compatible with XP. It is not about drawing pictures of a domain; it is about how you think of it, the language you use to talk about it, and how you organize your software to reflect your improving understanding of it. Eric thinks that learning about your problem domain is as likely to happen at the end of your project as at the beginning, and so refactoring is a big part of his technique. "The book is a fun read. Eric has lots of interesting stories, and he has a way with words. I see this book as essential reading for software developers-it is a future classic." - Ralph Johnson , author of Design Patterns "If you don't think you are getting value from your investment in object-oriented programming, this book will tell you what you've forgotten to do. "Eric Evans convincingly argues for the importance of domain modeling as the central focus of development and provides a solid framework and set of techniques for accomplishing it. This is timeless wisdom, and will hold up long after the methodologies du jour have gone out of fashion." - Dave Collins , author of Designing Object-Oriented User Interfaces "Eric weaves real-world experience modeling-and building-business applications into a practical, useful book. Written from the perspective of a trusted practitioner, Eric's descriptions of ubiquitous language, the benefits of sharing models with users, object life-cycle management, logical and physical application structuring, and the process and results of deep refactoring are major contributions to our field." - Luke Hohmann , author of Beyond Software Architecture "This book belongs on the shelf of every thoughtful software developer." - Kent Beck "What Eric has managed to capture is a part of the design process that experienced object designers have always used, but that we have been singularly unsuccessful as a group in conveying to the rest of the industry. We've given away bits and pieces of this knowledge...but we've never organized and systematized the principles of building domain logic. This book is important." - Kyle Brown , author of Enterprise Java™ Programming with IBM ® WebSphere ® The software development community widely acknowledges that domain modeling is central to software design. Through domain models, software developers are able to express rich functi...

    Abstract: With its rep for being the sort of machine that won't intimidate even the most inexperienced users, what's the appeal of the Mac® for hard-core geeks? The Mac has always been an efficient tool, pleasant to use and customize, and eminently hackable. But now with Mac OS® X's BSD core, many a Unix® developer has found it irresistible. The latest version of Mac OS X, called Panther, makes it even easier for users to delve into the underlying Unix operating system. In fact, you can port Linux® and Unix applications and run them side-by-side with your native Aqua® apps right on the Mac desktop. Still, even experienced Unix users may find themselves in surprisingly unfamiliar territory as they set out to explore Mac OS X. Even if you know Macs through and through, Mac OS X Panther is unlike earlier Macs, and it's radically different from the Unix you've used before. Enter Mac OS X Panther for Unix Geeks by Brian Jepson and Ernest E. Rothman, two Unix geeks who found themselves in the same place you are. The new edition of this book is your guide to figuring out the BSD Unix system and Panther-specific components that you may find challenging. This concise book will ease you into the Unix innards of Mac OS X Panther, covering such topics as: A quick overview of the Terminal application, including Terminal alternatives like iTerm and GLterm Understanding Open Directory (LDAP) and NetInfo Issues related to using the GNU C Compiler (GCC) Library linking and porting Unix software An overview of Mac OS X Panther's filesystem and startup processes Creating and installing packages using Fink and Darwin Ports Building the Darwin kernel Using the Apple® X11 distribution for running X Windows® applications on top of Mac OS X The book wraps up with a quick manpage-style reference to the "Missing Manual Pages" --commands that come with Mac OS X Panther, although there are no manpages. If you find yourself disoriented by the new Mac environment, Mac OS X Panther for Unix Geeks will get you acclimated quickly to the foreign new areas of a familiar Unix landscape.

    Abstract: Kerberos, the single sign-on authentication system originally developed at MIT, deserves its name. It's a faithful watchdog that keeps intruders out of your networks. But it has been equally fierce to system administrators, for whom the complexity of Kerberos is legendary.Single sign-on is the holy grail of network administration, and Kerberos is the only game in town. Microsoft, by integrating Kerberos into Active Directory in Windows 2000 and 2003, has extended the reach of Kerberos to all networks large or small. Kerberos makes your network more secure and more convenient for users by providing a single authentication system that works across the entire network. One username; one password; one login is all you need.Fortunately, help for administrators is on the way. Kerberos: The Definitive Guide shows you how to implement Kerberos for secure authentication. In addition to covering the basic principles behind cryptographic authentication, it covers everything from basic installation to advanced topics like cross-realm authentication, defending against attacks on Kerberos, and troubleshooting.In addition to covering Microsoft's Active Directory implementation, Kerberos: The Definitive Guide covers both major implementations of Kerberos for Unix and Linux: MIT and Heimdal. It shows you how to set up Mac OS X as a Kerberos client. The book also covers both versions of the Kerberos protocol that are still in use: Kerberos 4 (now obsolete) and Kerberos 5, paying special attention to the integration between the different protocols, and between Unix and Windows implementations.If you've been avoiding Kerberos because it's confusing and poorly documented, it's time to get on board! This book shows you how to put Kerberos authentication to work on your Windows and Unix systems.

    Abstract: Java Data Objects revolutionizes the way Java developers interact with databases and other datastores. JDO allows you to store and retrieve objects in a way that's natural to Java programmers. Instead of working with JDBC or EJB's container-managed persistence, you work directly with your Java objects. You don't have to copy data to and from database tables or issue SELECTs to perform queries: your JDO implementation takes care of persistence behind-the-scenes, and you make queries based on the fields of your Java objects, using normal Java syntax. The result is software that is truly object-oriented: not code that is partially object-oriented, with a large database-shaped lump on the back end. JDO lets you save plain, ordinary Java objects, and does not force you to use different data models and types for dealing with storage. As a result, your code becomes easier to maintain, easier to re-use, and easier to test. And you're not tied to a specific database vendor: your JDO code is entirely database-independent. You don't even need to know whether the datastore is a relational database, an object database, or just a set of files. This book, written by the JDO Specification Lead and one of the key contributors to the JDO Specification, is the definitive work on the JDO API. It gives you a thorough introduction to JDO, starting with a simple application that demonstrates many of JDO's capabilities. It shows you how to make classes persistent, how JDO maps persistent classes to the database, how to configure JDO at runtime, how to perform transactions, and how to make queries. More advanced chapters cover optional features such as nontransactional access and optimistic transactions. The book concludes by discussing the use of JDO in web applications and J2EE environments. Whether you only want to read up on an interesting new technology, or are seriously considering an alternative to JDBC or EJB CMP, you'll find that this book is essential. It provides by far the most authoritative and complete coverage available.

    Abstract: With the spread of web-enabled desktop clients and web-server based applications, developers can no longer afford to treat security as an afterthought. It's one topic, in fact, that .NET forces you to address, since Microsoft has placed security-related features at the core of the .NET Framework. Yet, because a developer's carelessness or lack of experience can still allow a program to be used in an unintended way, Programming .NET Security shows you how the various tools will help you write secure applications.The book works as both a comprehensive tutorial and reference to security issues for .NET application development, and contains numerous practical examples in both the C# and VB.NET languages. With Programming .NET Security , you will learn to apply sound security principles to your application designs, and to understand the concepts of identity, authentication and authorization and how they apply to .NET security. This guide also teaches you to: use the .NET run-time security features and .NET security namespaces and types to implement best-practices in your applications, including evidence, permissions, code identity and security policy, and role based and Code Access Security (CAS) use the .NET cryptographic APIs , from hashing and common encryption algorithms to digital signatures and cryptographic keys, to protect your data. use COM+ component services in a secure manner If you program with ASP.NET will also learn how to apply security to your applications. And the book also shows you how to use the Windows Event Log Service to audit Windows security violations that may be a threat to your solution.Authors Adam Freeman and Allen Jones, early .NET adopters and long-time proponents of an "end-to-end" security model, based this book on their years of experience in applying security policies and developing products for NASDAQ, Sun Microsystems, Netscape, Microsoft, and others. With the .NET platform placing security at center stage, the better informed you are, the more secure your project will be.

    Abstract: This book, which has been officially adopted by the Samba Team and is under the GNU Free Documentation License (FDL), is a comprehensive guide to Samba administration. The 2nd edition focuses on Samba 2.2 and covers the most important features of 3.0, which was under development as this book went to print. Samba is a cross-platform triumph: it turns a Unix or Linux system into a file and print server for Microsoft Windows network clients. Samba is so robust, flexible, fast, and secure that many people are choosing it over Windows NT/2000/XP for their file and print services. Samba is also free software, licensed under the GNU General Public License. This book will help you make file and print sharing as robust, powerful, and efficient as possible. The authors delve into the internals of the Windows activities and protocols to an unprecedented degree, explaining the strengths and weaknesses of each feature in Windows domains and in Samba itself. Using Samba takes you from basic installation and configuration--on both the client and server side, for a wide range of systems--to subtle details of security, cross-platform compatibility, and resource discovery that make the difference between whether a user sees the folder they expect or a cryptic error message. The range of this book knows few bounds. Wondering how to integrate Samba's authentication with that of a Windows PDC? How to get Samba to serve Microsoft Dfs shares? How to share files on Mac OS X? These and a dozen other issues of interest to system administrators are covered. A whole chapter is dedicated to troubleshooting. Whether you're playing on one note or a full three-octave range, on your personal computer or an enterprise network, Using Samba will give you an efficient and secure server.

    Abstract: Computer security is an ongoing process, a relentless contest between system administrators and intruders. A good administrator needs to stay one step ahead of any adversaries, which often involves a continuing process of education. If you're grounded in the basics of security, however, you won't necessarily want a complete treatise on the subject each time you pick up a book. Sometimes you want to get straight to the point. That's exactly what the new Linux Security Cookbook does. Rather than provide a total security solution for Linux computers, the authors present a series of easy-to-follow recipes--short, focused pieces of code that administrators can use to improve security and perform common tasks securely.The Linux Security Cookbook includes real solutions to a wide range of targeted problems, such as sending encrypted email within Emacs, restricting access to network services at particular times of day, firewalling a webserver, preventing IP spoofing, setting up key-based SSH authentication, and much more. With over 150 ready-to-use scripts and configuration files, this unique book helps administrators secure their systems without having to look up specific syntax. The book begins with recipes devised to establish a secure system, then moves on to secure day-to-day practices, and concludes with techniques to help your system stay secure.Some of the "recipes" you'll find in this book are: Controlling access to your system from firewalls down to individual services, using iptables, ipchains, xinetd, inetd, and more Monitoring your network with tcpdump, dsniff, netstat, and other tools Protecting network connections with Secure Shell (SSH) and stunnel Safeguarding email sessions with Secure Sockets Layer (SSL) Encrypting files and email messages with GnuPG Probing your own security with password crackers, nmap, and handy scripts This cookbook's proven techniques are derived from hard-won experience. Whether you're responsible for security on a home Linux system or for a large corporation, or somewhere in between, you'll find valuable, to-the-point, practical recipes for dealing with everyday security issues. This book is a system saver.

    Abstract: When Practical Unix Security was first published more than a decade ago, it became an instant classic. Crammed with information about host security, it saved many a Unix system administrator from disaster. The second edition added much-needed Internet security coverage and doubled the size of the original volume. The third edition is a comprehensive update of this very popular book - a companion for the Unix/Linux system administrator who needs to secure his or her organization's system, networks, and web presence in an increasingly hostile world.Focusing on the four most popular Unix variants today--Solaris, Mac OS X, Linux, and FreeBSD--this book contains new information on PAM (Pluggable Authentication Modules), LDAP, SMB/Samba, anti-theft technologies, embedded systems, wireless and laptop issues, forensics, intrusion detection, chroot jails, telephone scanners and firewalls, virtual and cryptographic filesystems, WebNFS, kernel security levels, outsourcing, legal issues, new Internet protocols and cryptographic algorithms, and much more. Practical Unix & Internet Security consists of six parts: Computer security basics: introduction to security problems and solutions, Unix history and lineage, and the importance of security policies as a basic element of system security.

    Abstract: Mention wireless networks, and the question of security will soon follow. It's not surprising that in spite of compelling business arguments for going wireless, many companies are holding back because of security concerns. But, while it's true that wireless networks create security issues that don't exist in wired networks, the issues are not insurmountable. 802.11 Security shows how you can plan for and successfully contend with security obstacles in your wireless deployment. This authoritative book not only explains the security issues, but shows you how to design and build a your own secure wireless network. 802.11 Security covers the entire process of building secure 802.11-based wireless networks, in particular, the 802.11b ("Wi-Fi") specification. The authors provide detailed coverage of security issues unique to wireless networking, such as Wireless Access Points (WAP), bandwidth stealing, and the problematic Wired Equivalent Privacy component of 802.11. You'll learn how to configure a wireless client and to set up a WAP using either Linux or Free BSD. You'll also find thorough information on controlling network access and encrypting client traffic. Beginning with an introduction to 802.11b in general, the book gives you a broad basis in theory and practice of wireless security, dispelling some of the myths along the way. In doing so, they provide you with the technical grounding required to think about how the rest of the book applies to your specific needs and situations. Next, the book details the technical setup instructions needed for both the Linux and FreeBSD operating systems. Some of the topics covered include: Station Security for Linux, FreeBSD, Open BSD, Mac OS X and Windows Setting Up Access Point Security Gateway Security, including building Gateways, firewall Rules, Auditing, etc. Authentication and Encryption FreeBSD IPsec client and gateway configuration Linux IPsec client and gateway configuration 802.1x authentication 802.11 Security is a book whose time has come. If you are a network, security, or systems engineer, or anyone interested in deploying 802.11b-based systems, you'll want this book beside you every step of the way.

    Abstract: One of the most significant features of Visual Basic .NET is the full support of object-oriented programming. For years, developers have been asking for it, but you may not be quite sure how it can help to create and maintain scalable .NET applications. VB.NET is a language that facilitates object-oriented programming, but does not guarantee good object-oriented code. That's where Object-Oriented Programming with Visual Basic .NET comes in. It will show you how to think about similarities in your application logic and how to design and create objects that maximize the benefit and power the .NET Framework enables. The concept of separating the interface from the implementation has been around for years, but with Object-Oriented Programming with Visual Basic .NET you'll put it all into practice and you'll never willingly go back to those old ways. With chapters on object fundamentals and class anatomy, you'll lay a foundation that will prepare you to think and apply code reuse principles. Following that, you'll be ready to dive deep into code and the dynamic ecology that it interacts with. Inheritance, containment, polymorphism, overloading, and overriding are just the beginning of this adventure. From there, you'll discover exception handling, reflection, serialization, and I/O. Packed with examples that will guide you through every step, Object-Oriented Programming with Visual Basic .NET is a guide for those with some programming experience. This book is for those who know Visual Basic 6.0 and are ready or have started the process of developing with Visual Basic .NET. It is an essential tool that will build your skills, as you become a master of Visual Basic .NET. It is one thing to know how to write object-oriented code. Knowing the when and the why is what makes good programmers. That's exactly what you'll know after reading this book.

    Abstract: Cocoa® is more than just a collection of classes, and is certainly more than a simple framework. Cocoa is a complete API set, class library, framework, and development environment for building applications and tools to run on Mac OS® X. With over 240 classes, Cocoa is divided into two essential frameworks: Foundation and Application Kit. Above all else, Cocoa is a toolkit for creating Mac OS X application interfaces, and it provides access to all of the standard Aqua® interface components such as menus, toolbars, windows, buttons, to name a few. Cocoa in a Nutshell begins with a complete overview of Cocoa's object classes. It provides developers who may be experienced with other application toolkits the grounding they'll need to start developing Cocoa applications. Common programming tasks are described, and many chapters focus on the larger patterns in the frameworks so developers can understand the larger relationships between the classes in Cocoa, which is essential to using the framework effectively. Cocoa in a Nutshell is divided into two parts, with the first part providing a series of overview chapters that describe specific features of the Cocoa frameworks. Information you'll find in Part I includes: An overview of the Objective-C language Coverage of the Foundation and Application Kit frameworks Overviews of Cocoa's drawing and text handling classes Network services such as hosts, Rendezvous URL services, sockets, and file handling Distributed notifications and distributed objects for interapplication communication Extending Cocoa applications with other frameworks, including the AddressBook, DiscRecording, and Messaging frameworks The second half of the book is a detailed quick reference to Cocoa's Foundation and Application Kit (AppKit) classes. A complement to Apple's documentation, Cocoa in a Nutshell is the only reference to the classes, functions, types, constants, protocols, and methods that make up Cocoa's Foundation and Application Kit frameworks, based on the Jaguar release (Mac OS X 10.2). Peer-reviewed and approved by Apple's engineers to be part of the Apple Developer Connection (ADC) Series, Cocoa in a Nutshell is the book developers will want close at hand as they work. It's the desktop quick reference they can keep by their side to look something up quickly without leaving their work. Cocoa in a Nutshell is the book developers will want close at hand as they work.

    Abstract: With over 100,000 installations, the Snort open-source network instrusion detection system is combined with other free tools to deliver IDS defense to medium - to small-sized companies, changing the tradition of intrusion detection being affordable only for large companies with large budgets. Until now, Snort users had to rely on the official guide available on snort.org. That guide is aimed at relatively experience snort administrators and covers thousands of rules and known exploits. The lack of usable information made using Snort a frustrating experience. The average Snort user needs to learn how to actually get their systems up-and-running. Snort Intrusion Detection provides readers with practical guidance on how to put Snort to work. Opening with a primer to intrusion detection and Snort, the book takes the reader through planning an installation to building the server and sensor, tuning the system, implementing the system and analyzing traffic, writing rules, upgrading the system, and extending Snort.

    Abstract: More often than not, the words "sendmail configuration" strikedread in the hearts of sendmail and system administrators--and notwithout reason. sendmail configuration languages are as complex asany other programming languages, but used much moreinfrequently--only when sendmail is installed or configured. Theaverage system administrator doesn't get enough practice to trulymaster this inscrutable technology. Fortunately, there's help. The sendmail Cookbook provides step-by-step solutions for theadministrator who needs to solve configuration problems fast. Sayyou need to configure sendmail to relay mail for your clientswithout creating an open relay that will be abused by spammers. Arecipe in the Cookbook shows you how to do just that. No morewading through pages of dense documentation and tutorials andcreating your own custom solution--just go directly to the recipethat addresses your specific problem. Each recipe in the sendmail Cookbook outlines a configuration problem, presentsthe configuration code that solves that problem, and then explainsthe code in detail. The discussion of the code is critical becauseit provides the insight you need to tweak the code for your owncircumstances. The sendmail Cookbook begins with an overviewof the configuration languages, offering a quick how-to fordownloading and compiling the sendmail distribution. Next, you'llfind a baseline configuration recipe upon which many of thesubsequent configurations, or recipes, in the book are based.Recipes in the following chapters stand on their own and offersolutions for properly configuring important sendmail functionssuch as: Delivering and forwarding mail Relaying Masquerading Routing mail Controlling spam Strong authentication Securing the mail transport Managing the queue Securing sendmail sendmail Cookbook is more than just a new approach todiscussing sendmail configuration. The book also provides lots ofnew material that doesn't get much coverage elsewhere--STARTTLS andAUTH are given entire chapters, and LDAP is covered in recipesthroughout the book. But most of all, this book is about savingtime--something that most system administrators have in shortsupply. Pick up the sendmail Cookbook and say good-bye tosendmail dread.

    Abstract: Renowned for its friendliness, Mac OS® X has delighted many a loyal Mac® user with its combined ease use and underlying strength. By no means simplistic, its intelligently designed operating system and user interface boast of sophistication and power, while still offering accessibility to even the most inexperienced computer users. But Mac OS X has gone one step further: it's turned unsuspecting Mac users into Unix® users, too. Perhaps you're already familiar with Unix, just not on the Mac. Or perhaps you opened your Utilities folder, spotted the Terminal icon and double-clicked on it just to see what it does. Suddenly faced with a command line interface, you may have asked, "What does this mean?" followed by the most pressing question, "Why on earth would I ever want to venture into this seemingly user-unfriendly territory?" The new edition of Learning Unix for Mac OS X Panther answers these questions and more. This compact book provides a user-friendly tour for the uninitiated of the Mac's Unix base. You can safely explore Terminal and familiarize yourself with the command line, learning as you go about the hundreds of Unix programs that come with your Mac. You'll begin to understand the power and flexibility of Unix. And if Unix isn't new to you, you'll discover how it translates into this latest Mac incarnation. Updated to cover Mac OS X Panther (Mac OS X 10.3), this book will keep you current with the latest features of your Mac. Learning Unix for Mac OS X Panther begins with a quick but in-depth introduction to Terminal and the command line interface.

    Abstract: Written by experts on the Microsoft® .NET programming platform, ADO.NET in a Nutshell delivers everything .NET programmers will need to get a jump-start on ADO.NET technology or to sharpen their skills even further. In the tradition of O'Reilly's In a Nutshell Series, ADO.NET in a Nutshell is the most complete and concise source of ADO.NET information available.ADO.NET is the suite of data access technologies in the .NET Framework that developers use to build applications services accessing relational data and XML. Connecting to databases is a fundamental part of most applications, whether they are web, Windows®, distributed, client/server, XML Web Services, or something entirely different. But ADO.NET is substantially different from Microsoft's previous data access technologies--including the previous version of ADO--so even experienced developers need to understand the basics of the new disconnected model before they start programming with it.Current with the .NET Framework 1.1, ADO.NET in a Nutshell offers one place to look when you need help with anything related to this essential technology, including a reference to the ADO.NET namespaces and object model. In addition to being a valuable reference, this book provides a concise foundation for programming with ADO.NET and covers a variety of issues that programmers face when developing web applications or Web Services that rely on database access. Using C#, this book presents real world, practical examples that will help you put ADO.NET to work immediately.Topics covered in the book include: An Introduction to ADO.NET Connections, Commands and DataReaders Disconnected Data Advanced DataSets Transactions DataViews and Data Binding XML and the DataSet Included with the book is a Visual Studio .NET add-in that integrates the entire reference directly into your help files. When combining ADO.NET in a Nutshell with other books from O'Reilly's .NET In a Nutshell series, you'll have a comprehensive, detailed and independent reference collection that will help you become more productive.

    Abstract: Elegant, sleek, powerful, and stable, Mac OS X has delighted many a loyal Mac user, and gone one step further--it's turned them into Unix users, too. Perhaps you're already familiar with Unix, just not on the Mac. Or perhaps you opened your Utilities folder, spotted the Terminal icon and double-clicked on it just to see what it does. Suddenly faced with a command line interface, you probably asked what does it mean, and the more pressing question, why on earth would you ever want to venture into this seemingly user-unfriendly territory? The new edition of Learning Unix for Mac OS X answers these questions and more. This compact book provides a user-friendly tour of your Mac's Unix base. As you explore Terminal and familiarize yourself with the command line, you'll also learn about the hundreds of Unix programs that come with your Mac and begin to understand the power and flexibility of Unix. And if Unix isn't new to you, you'll discover how it translates into this new Mac incarnation. Updated to cover Jaguar (Mac OS X, 10.2), this book will keep you current with the latest features of your Mac. The book begins with a quick but in-depth introduction to Terminal and the command line interface. After learning about launching and configuring the Terminal application, you'll find out how to manage, create, edit, and transfer files. You'll find all the common commands simply explained with accompanying examples, exercises, and opportunities for experimentation. There are even problem checklists to help you along the way if you get stuck. You'll learn how to: Customize your shell environment Manage files and directories Successfully print from the Unix command line Edit and create files with the vi editor Perform remote logins Access Internet functions Understand pipes and filters Use background processing Use Fink, an easy way to install open source Unix software on Mac OS X With Terminal, you'll access areas of your Mac that you just can't get to from the desktop.

    Abstract: Do you need to develop flexible software that can be customized quickly? Do you need to add the power and efficiency of frameworks to your software? The ADAPTIVE Communication Environment (ACE) is an open-source toolkit for building high-performance networked applications and next-generation middleware. ACE's power and flexibility arise from object-oriented frameworks, used to achieve the systematic reuse of networked application software. ACE frameworks handle common network programming tasks and can be customized using C++ language features to produce complete distributed applications. C++ Network Programming, Volume 2, focuses on ACE frameworks, providing thorough coverage of the concepts, patterns, and usage rules that form their structure. This book is a practical guide to designing object-oriented frameworks and shows developers how to apply frameworks to concurrent networked applications. C++ Networking, Volume 1, introduced ACE and the wrapper facades, which are basic network computing ingredients. Volume 2 explains how frameworks build on wrapper facades to provide higher-level communication services. Written by two experts in the ACE community, this book contains: An overview of ACE frameworks Design dimensions for networked services Descriptions of the key capabilities of the most important ACE frameworks Numerous C++ code examples that demonstrate how to use ACE frameworks C++ Network Programming, Volume 2, teaches how to use frameworks to write networked applications quickly, reducing development effort and overhead. It will be an invaluable asset to any C++ developer working on networked applications.

    Abstract: Learning Cocoa with Objective-C is the "must-have" book for people who want to develop applications for Mac OS X, and is the only book approved and reviewed by Apple engineers. Based on the Jaguar release of Mac OS X 10.2, this edition of Learning Cocoa includes examples that use the Address Book and Universal Access APIs. Also included is a handy quick reference card, charting Cocoa's Foundation and AppKit frameworks, along with an Appendix that includes a listing of resources essential to any Cocoa developer--beginning or advanced.Completely revised and updated, this 2nd edition begins with some simple examples to familiarize you with the basic elements of Cocoa programming as well Apple's Developer Tools, including Project Builder and Interface Builder.After introducing you to Project Builder and Interface Builder, it brings you quickly up to speed on the concepts of object-oriented programming with Objective-C, the language of choice for building Cocoa applications. From there, each chapter presents a different sample program for you to build, with easy to follow, step-by-step instructions to teach you the fundamentals of Cocoa programming. The techniques you will learn in each chapter lay the foundation for more advanced techniques and concepts presented in later chapters.You'll learn how to: Effectively use Apple's suite of Developer Tools, including Project Builder and Interface Builder Build single- and multiple-window document-based applications Manipulate text data using Cocoa's text handling capabilities Draw with Cocoa Add scripting functionality to your applications Localize your application for multiple language support Polish off your application by adding an icon for use in the Dock, provide Help, and package your program for distribution Each chapter ends with a series of Examples, challenging you to test your newly-learned skills by tweaking the application you've just built, or to go back to an earlier example and add to it some new functionality. Solutions are provided in the Appendix, but you're encouraged to learn by trying.Extensive programming experience is not required to complete the examples in the book, though experience with the C programming language will be helpful. If you are familiar with an object-oriented programming language such as Java or Smalltalk, you will rapidly come up to speed with the Objective-C language. Otherwise, basic object-oriented and language concepts are covered where needed.

    Abstract: Many serious Java programmers, especially enterprise Java programmers, consider the new I/O API--called NIO for New Input/Output--the most important feature in the 1.4 version of the Java 2 Standard Edition. The NIO package includes many things that have been missing from previous editions of Java that are critical to writing high-performance, large-scale applications: improvements in the areas of buffer management, scalable network and file I/O, character-set support, and regular expression matching. Most of all, it boosts performance and speed dramatically. Java NIO explores the new I/O capabilities of version 1.4 in detail and shows you how to put these features to work to greatly improve the efficiency of the Java code you write. This compact volume examines the typical challenges that Java programmers face with I/O and shows you how to take advantage of the capabilities of the new I/O features. You?ll learn how to put these tools to work using examples of common, real-world I/O problems and see how the new features have a direct impact on responsiveness, scalability, and reliability. The book includes: A rundown of the new features in NIO Basic and advanced I/O Concepts Binary I/O and the new buffer classes Memory mapped files and file locking Character I/O: encoding, decoding and transforming character data Regular Expressions and the new java.util.regex package Muliplexing with java.nio Because the NIO APIs supplement the I/O features of version 1.3, rather than replace them, you'll also learn when to use new APIs and when the older 1.3 I/O APIs are better suited to your particular application. Java NIO is for any Java programmer who is interested in learning how to boost I/O performance, but if you're developing applications where performance is critical, such as game computing or large-scale enterprise applications, you'll want to give this book a permanent spot on your bookshelf. With the NIO APIs, Java no longer takes a backseat to any language when it comes to performance. Java NIO will help you realize the benefits of these exciting new features.

    Abstract: System Performance Tuning answers one of the most fundamental questions you can ask about your computer: How can I get it to do more work without buying more hardware? In the current economic downturn, performance tuning takes on a new importance. It allows system administrators to make the best use of existing systems and minimize the purchase of new equipment. Well-tuned systems save money and time that would otherwise be wasted dealing with slowdowns and errors. Performance tuning always involves compromises; unless system administrators know what the compromises are, they can't make intelligent decisions.Tuning is an essential skill for system administrators who face the problem of adapting the speed of a computer system to the speed requirements imposed by the real world. It requires a detailed understanding of the inner workings of the computer and its architecture. System Performance Tuning covers two distinct areas: performance tuning, or the art of increasing performance for a specific application, and capacity planning, or deciding what hardware best fulfills a given role. Underpinning both subjects is the science of computer architecture. This book focuses on the operating system, the underlying hardware, and their interactions. Topics covered include: Real and perceived performance problems, introducing capacity planning and performance monitoring (highlighting their strengths and weaknesses). An integrated description of all the major tools at a system administrator's disposal for tracking down system performance problems. Background on modern memory handling techniques, including the memory-caching filesystem implementations in Solaris and AIX. Updated sections on memory conservation and computing memory requirements. In depth discussion of disk interfaces, bandwidth capacity considerations, and RAID systems. Comprehensive discussion of NFS and greatly expanded discussion of networking. Workload management and code tuning. Special topics such as tuning Web servers for various types of content delivery and developments in cross-machine parallel computing For system administrators who want a hands-on introduction to system performance, this is the book to recommend.

    Abstract: Linux consistently turns up high in the list of popular Internet servers, whether it's for the Web, anonymous FTP, or general services like DNS and routing mail. But security is uppermost on the mind of anyone providing such a service. Any server experiences casual probe attempts dozens of time a day, and serious break-in attempts with some frequency as well. As the cost of broadband and other high-speed Internet connectivity has gone down, and its availability has increased, more Linux users are providing or considering providing Internet services such as HTTP, Anonymous FTP, etc., to the world at large. At the same time, some important, powerful, and popular Open Source tools have emerged and rapidly matured--some of which rival expensive commercial equivalents--making Linux a particularly appropriate platform for providing secure Internet services. Building Secure Servers with Linux will help you master the principles of reliable system and network security by combining practical advice with a firm knowledge of the technical tools needed to ensure security. The book focuses on the most common use of Linux--as a hub offering services to an organization or the larger Internet--and shows readers how to harden their hosts against attacks. Author Mick Bauer, a security consultant, network architect, and lead author of the popular Paranoid Penguin column in Linux Journal, carefully outlines the security risks, defines precautions that can minimize those risks, and offers recipes for robust security. The book does not cover firewalls, but covers the more common situation where an organization protects its hub using other systems as firewalls, often proprietary firewalls. The book includes: Precise directions for securing common services, including the Web, mail, DNS, and file transfer. Ancillary tasks, such as hardening Linux, using SSH and certificates for tunneling, and using iptables for firewalling. Basic installation of intrusion detection tools. Writing for Linux users with little security expertise, the author explains security concepts and techniques in clear language, beginning with the fundamentals. Building Secure Servers with Linux provides a unique balance of "big picture" principles that transcend specific software packages and version numbers, and very clear procedures on securing some of those software packages. An all-inclusive resource for Linux users who wish to harden their systems, the book covers general security as well as k...

    Abstract: Java and SOAP provides Java developers with an in-depth look at SOAP (the Simple Object Access Protocol). Of course, it covers the basics: what SOAP is, why it's soared to a spot on the Buzzwords' Top Ten list, and what its features and capabilities are. And it shows you how to work with some of the more common Java APIs in the SOAP world: Apache SOAP and GLUE.In addition to covering the basics such as the structure of a SOAP message, SOAP encoding, and building simple services using RPC and messaging, Java and SOAP covers many topics that are essential to real-world development. Although SOAP has native support for an impressive number of object types, the nature of modern programming means that whatever SOAP gives you is not enough. When do you need to add support for your own object types, and how do you do it? How do you handle errors, and how do you add your own information to Fault messages? How do you handle attachments?In an ideal world, you could live entirely within Java, and ignore the SOAP messages being send back and forth: you'd be able to write Java code and let the SOAP APIs work behind the scenes. However, we're not yet in that ideal world, and won't be for some time. Therefore, Java and SOAP pays particular attention to how SOAP messages are encoded. It doesn't just explain the document types, but shows how the documents are used in practice as they are generated by the different APIs. If you ever have to debug interoperability problems, you'll find that this information is indispensable.We've always found that the best software is written by people who understand what's happening under the hood. SOAP is no different. Let's say you need to write a custom serializer to create a SOAP representation of a structure. How do you know that your encoding is efficient? There's one definitive answer: look at the SOAP documents it produces! Java and SOAP also discusses interoperability between the major SOAP platforms, including Microsoft's .NET, SOAP messaging, SOAP attachments, message routing, and a preview of the forthcoming AXIS APIs and server. If you're a Java developer who would like to start working with SOAP, this is the book you need to get going.

    Abstract: Ruby is an absolutely pure object-oriented scripting language written in C and designed with Perl and Python capabilities in mind. While its roots are in Japan, Ruby is slowly but surely gaining ground in the US. The goal of Yukihiro Matsumoto, creator of Ruby and author of this book, is to incorporate the strengths of languages like Perl, Python, Lisp and Smalltalk. Ruby is a genuine attempt to combine the best of everything in the scripting world. Since 1993, Ruby mailing lists have been established, Web pages have formed, and a community has grown around it. The language itself is very good at text processing and is notable for its broad object orientation. Ruby is portable and runs under GNU/Linux (and other Unices) as well as DOS, MS Windows and Mac.With Ruby in a Nutshell , Matsumoto offers a practical reference to the features of this new language including the command-line options, syntax, built-in variables, functions, and many commonly used classes and modules. This guide covers the current stable version of Ruby (1.6), yet is applicable to the development version 1.7 and the next planned stable version 1.8. You will find a thorough description of Ruby's language syntax, and a description of the core functionality built into the standard Ruby interpreter, which has more than 800 built-in methods in 42 classes and modules.Ruby finds its power through its built-in libraries, and this handy volume take you through the many useful libraries that come with the standard Ruby distribution--from network access via HTTP and CGI programming, to data persistence using the DBM library. This book concludes with coverage of the unique tools that come with Ruby, including the debugger, profiler, and irb (or interactive ruby.)Find out how Ruby combines the strengths of other languages, and why it has captured the interest of so many open source programmers. As part of the successful "in a nutshell" series of books from O'Reilly & Associates, Ruby in a Nutshell is for readers who want a single desktop reference for all their needs.

    Abstract: For people who create and modify text files, sed and awk are power tools for editing. sed, awk, and regular expressions allow programmers and system administrators to automate editing tasks that need to be performed on one or more files, to simplify the task of performing the same edits on multiple files, and to write conversion programs.The sed & awk Pocket Reference is a companion volume to sed & awk, Second Edition, Unix in a Nutshell, Third Edition , and Effective awk Programming, Third Edition . This new edition has expanded coverage of gawk (GNU awk), and includes sections on: An overview of sed and awk?s command line syntax Alphabetical summaries of commands, including nawk and gawk Profiling with pgawk Coprocesses and sockets with gawk Internationalization with gawk A listing of resources for sed and awk users This small book is a handy reference guide to the information presented in the larger volumes. It presents a concise summary of regular expressions and pattern matching, and summaries of sed and awk.Arnold Robbins, an Atlanta native now happily living in Israel, is a professional programmer and technical author and coauthor of various O'Reilly Unix titles. He has been working with Unix systems since 1980, and currently maintains gawk and its documentation.

    Abstract: This complete guide to setting up and running a TCP/IP network is essential for network administrators, and invaluable for users of home systems that access the Internet. The book starts with the fundamentals -- what protocols do and how they work, how addresses and routing are used to move data through the network, how to set up your network connection -- and then covers, in detail, everything you need to know to exchange information via the Internet.Included are discussions on advanced routing protocols (RIPv2, OSPF, and BGP) and the gated software package that implements them, a tutorial on configuring important network services -- including DNS, Apache, sendmail, Samba, PPP, and DHCP -- as well as expanded chapters on troubleshooting and security. TCP/IP Network Administration is also a command and syntax reference for important packages such as gated, pppd, named, dhcpd, and sendmail.With coverage that includes Linux, Solaris, BSD, and System V TCP/IP implementations, the third edition contains: Overview of TCP/IP Delivering the data Network services Getting startedM Basic configuration Configuring the interface Configuring routing Configuring DNS Configuring network servers Configuring sendmail Configuring Apache Network security Troubleshooting Appendices include dip , ppd , and chat reference, a gated reference, a dhcpd reference, and a sendmail reference This new edition includes ways of configuring Samba to provide file and print sharing on networks that integrate Unix and Windows, and a new chapter is dedicated to the important task of configuring the Apache web server. Coverage of network security now includes details on OpenSSH, stunnel, gpg, iptables, and the access control mechanism in xinetd. Plus, the book offers updated information about DNS, including details on BIND 8 and BIND 9, the role of classless IP addressing and network prefixes, and the changing role of registrars.Without a doubt, TCP/IP Network Administration, 3rd Edition is a must-have for all network administrators and anyone who deals with a network that transmits data over the Internet.

    Abstract: Nothing is as constant as change, and this is as true in enterprise computing as anywhere else. Since Java Enterprise in a Nutshell was first published in September of 1999, a dozen or more new APIs have been added to the platform, reflecting the new and different ways developers implement their enterprise objectives. And now developers are being called on to add even greater, more complex levels of interconnectivity to their applications, as the concepts behind Web Services solidify and implementation decisions need coding. Java developers today need a clear understanding of the new APIs, tools, capabilities and pitfalls in J2EE 2.0 so they can plan a technology and implementation strategy for new enterprise projects. Fortunately, this is exactly what they get with the new Java Enterprise in a Nutshell, 2nd edition ! Completely revised and updated for the new 2.0 version of Sun Microsystems Java Enterprise Edition software, Java Enterprise in a Nutshell 2nd edition covers all of the J2EE APIs, including RMI, Java IDL, JDBC, JNDI, Java Servlet, and Enterprise JavaBeans, with a fast-paced tutorial and compact reference on each technology. Then Java Enterprise in a Nutshell goes even further, providing a classic O'Reilly-style quick reference for all of the classes in the various packages that comprise the Enterprise APIs - covering the core enterprise APIs as well as numerous standard extensions.

    Abstract: As a network administrator, auditor or architect, you know the importance of securing your network and finding security solutions you can implement quickly. This succinct book departs from other security literature by focusing exclusively on ways to secure Cisco routers, rather than the entire network. The rational is simple: If the router protecting a network is exposed to hackers, then so is the network behind it. Hardening Cisco Routers is a reference for protecting the protectors. Included are the following topics: The importance of router security and where routers fit into an overall security plan Different router configurations for various versions of Cisco?s IOS Standard ways to access a Cisco router and the security implications of each Password and privilege levels in Cisco routers Authentication, Authorization, and Accounting (AAA) control Router warning banner use (as recommended by the FBI) Unnecessary protocols and services commonly run on Cisco routers SNMP security Anti-spoofing Protocol security for RIP, OSPF, EIGRP, NTP, and BGP Logging violations Incident response Physical security Written by Thomas Akin, an experienced Certified Information Systems Security Professional (CISSP) and Certified Cisco Academic Instructor (CCAI), the book is well organized, emphasizing practicality and a hands-on approach. At the end of each chapter, Akin includes a Checklist that summarizes the hardening techniques discussed in the chapter. The Checklists help you double-check the configurations you have been instructed to make, and serve as quick references for future security procedures.Concise and to the point, Hardening Cisco Routers supplies you with all the tools necessary to turn a potential vulnerability into a strength. In an area that is otherwise poorly documented, this is the one book that will help you make your Cisco routers rock solid.
