Learn to harness the programming power that comes standard with all unix and linux systems (including Apple's OSX). This guide encourages hands-on experimentation by including actual scripts that feature the korn shell (ksh), awk, and sed.

Get to grips with a new technology, understand what it is and what it can do for you, and then get to work with the most important features and tasks. A practical, hands-on tutorial approach that explores the concepts of PowerShell in a friendly manner, taking an adhoc approach to each topic. If you are an administrator who is new to PowerShell or are looking to get a good grounding in these new features, this book is ideal for you. It's assumed that you will have some experience in PowerShell and Windows Server, as well being familiar with the PowerShell command-line.

This book is a fast-paced guide with practical, hands-on recipes which will show you how to prototype Beagleboard-based audio/video applications using Matlab/Simlink and Sourcery Codebench on a Windows host. Beagleboard Embedded Projects is great for students and academic researchers who have practical ideas and who want to build a proof-of-concept system on an embedded hardware platform quickly and efficiently. It is also useful for product design engineers who want to ratify their applications and reduce the time-to-market. It is assumed that you are familiar with Matlab/Simulink and have some basic knowledge of computer hardware. Experience in Linux is favoured but not necessary, as our software development is purely on a Windows host.

Linux consistently appears high up in the list of popular Internet servers, whether it's for the Web, anonymous FTP, or general services such as DNS and delivering mail. But security is the foremost concern 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.

This highly regarded book, originally titled "Building Secure Servers with Linux," combines 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 Internet--and shows readers how to harden their hosts against attacks. An all-inclusive resource for Linux users who wish to harden their systems, "Linux Server Security" covers general security such as intrusion detection and firewalling a hub, as well as key services such as DNS, the Apache Web server, mail, and secure shell.

Author Michael D. Bauer, a security consultant, network architect, and lead author of the popular Paranoid Penguin column in the "Linux Journal," carefully outlines the security risks, defines precautions that can minimize those risks, and offers recipes for robust security. He is joined on several chapters by administrator and developer Bill Lubanovic.

A number of new security topics have been added for this edition, including:

Database security, with a focus on MySQL

Using OpenLDAP for authentication

An introduction to email encryption

The Cyrus IMAP service, a popular mail delivery agent

The vsftpd FTP server

Geared toward Linux users with little security expertise, the author explainssecurity concepts and techniques in clear language, beginning with the fundamentals. "Linux Server Security" 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 on several popular distributions. With this book in hand, you'll have both the expertise and the tools to comprehensively secure your Linux system.

To the outside world, a "supercomputer" appears to be a single system. In fact, it's a cluster of computers that share a local area network and have the ability to work together on a single problem as a team. Many businesses used to consider supercomputing beyond the reach of their budgets, but new Linux applications have made high-performance clusters more affordable than ever. These days, the promise of low-cost supercomputing is one of the main reasons many businesses choose Linux over other operating systems.

This new guide covers everything a newcomer to clustering will need to plan, build, and deploy a high-performance Linux cluster. The book focuses on clustering for high-performance computation, although much of its information also applies to clustering for high-availability (failover and disaster recovery). The book discusses the key tools you'll need to get started, including good practices to use while exploring the tools and growing a system. You'll learn about planning, hardware choices, bulk installation of Linux on multiple systems, and other basic considerations. Then, you'll learn about software options that can save you hours--or even weeks--of deployment time.

Since a wide variety of options exist in each area of clustering software, the author discusses the pros and cons of the major free software projects and chooses those that are most likely to be helpful to new cluster administrators and programmers. A few of the projects introduced in the book include:

MPI, the most popular programming library for clusters. This book offers simple but realistic introductory examples along with some pointers for advanced use.

OSCAR and Rocks, two comprehensiveinstallation and administrative systems

openMosix (a convenient tool for distributing jobs), Linux kernel extensions that migrate processes transparently for load balancing

PVFS, one of the parallel filesystems that make clustering I/O easier

C3, a set of commands for administering multiple systems

Ganglia, OpenPBS, and cloning tools (Kickstart, SIS and G4U) are also covered. The book looks at cluster installation packages (OSCAR & Rocks) and then considers the core packages individually for greater depth or for folks wishing to do a custom installation. Guidelines for debugging, profiling, performance tuning, and managing jobs from multiple users round out this immensely useful book.

With today's hardware and chips, 90% of the time, interpreted unix scripts will perform as efficiently as code written in higher level languages - such as java. The difference is that, with unix scripts, you cut out about 80-90% of the lines of code, and have something that can easily be maintained and supported. Even if you still want to code in a higher level language, unix shell scripting is invaluable for support functions - such as moving around files, parsing log files, etc. An analyst or support person who uses the topics and examples in this book to master scripting can save him or herself literally hundreds of hours - especially when dealing with repetitive tasks with many lines of data.

This is the first book designed to help Windows developers decide not only which technologies to use but also how to use them. It teaches them to combine the wide variety of technologies that make up Windows DNA into effective solutions for their own enterprise application requirements. The author makes use of his long consulting experience in the client-server world to describe "best practices" that apply to building Windows DNA applications.

Despite Python's increasing popularity on Windows, Python Programming on Win32 is the first book to demonstrate how to use it as a serious Windows development and administration tool. This book addresses all the basic technologies for common integration tasks on Windows, explaining both the Windows issues and the Python code you need to glue things together.

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 LoginEnvironments

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.

The Mono Project is the much talked-about open source initiative to create a Unix implementation of Microsoft's .NET Development Framework. Its purpose is to allow Unix developers to build and deploy cross-platform .NET applications. The project has also sparked interest in developing components, libraries and frameworks with C#, the programming language of .NET.

The controversy? Some say Mono will become the preferred platform for Linux development, empowering Linux/Unix developers. Others say it will allow Microsoft to embrace, extend, and extinguish Linux. The controversy rages on, but--like many developers--maybe you've had enough talk and want to see what Mono is really all about.

There's one way to find out: roll up your sleeves, get to work, and see what you Mono can do. How do you start? You can research Mono at length. You can play around with it, hoping to figure things out for yourself. Or, you can get straight to work with "Mono: A Developer's Notebook"--a hands-on guide and your trusty lab partner as you explore Mono 1.0.

Light on theory and long on practical application, "Mono: A Developer's Notebook" bypasses the talk and theory, and jumps right into Mono 1.0. Diving quickly into a rapid tour of Mono, you'll work through nearly fifty mini-projects that will introduce you to the most important and compelling aspects of the 1.0 release. Using the task-oriented format of this new series, you'll learn how to acquire, install, and run Mono on Linux, Windows, or Mac OS X. You'll work with the various Mono components: Gtk#, the Common Language Runtime, the class libraries (both .NET and Mono-provided class libraries), IKVM and the Mono C# compiler. No other resourcewill take you so deeply into Mono so quickly or show you as effectively what Mono is capable of.

The new Developer's Notebooks series from O'Reilly covers important new tools for software developers. Emphasizing example over explanation and practice over theory, they focus on learning by doing--you'll get the goods straight from the masters, in an informal and code-intensive style that suits developers. If you've been curious about Mono, but haven't known where to start, this no-fluff, lab-style guide is the solution.

qmail has quietly become one of the most widely used applications on the Internet today. It's powerful enough to handle mail for systems with millions of users--Like Yahoo! Mail and Hotmail, while remaining compact and manageable enough for the smallest Unix- and Linux-based PC systems. Its component design makes it easy to extend and customize while keeping its key functions secure, so it's no wonder that adoption of qmail continues at a rapid pace.

The downside? Apparently none. Except that qmail's unique design can be disorienting to those familiar with other popular MTAs (Mail Transfer Agents). If you're coming from sendmail, for instance, you might have trouble recasting your problems and solutions in qmail terms. qmail first helps you establish a "qmail frame of mind," then explores the installation, configuration, administration, and extension of this powerful MTA. Whether you're installing from scratch or managing mailing lists with thousands of users, qmail provides detailed information about how to make qmail do precisely what you want

qmail concentrates on common tasks like moving a sendmail setup to qmail, or setting up a "POP toaster," a system that provides mail service to a large number of users on other computers sending and retrieving mail remotely. The book also fills crucial gaps in existing documentation, detailing exactly what the core qmail software does.

Topics covered include:

Installation and configuration, including patching qmail

Moving from sendmail to qmail

Handling locally and remotely originated messages

Managing virtual domains

Logging qmail activity

Tuning qmail performance

Running multiple copies of qmail on thesame computer

Mailing list setup and management

Integrating the qmail MTA with POP and IMAP delivery

Filtering out spam and viruses

If you need to manage mailing lists, large volumes of mail, or simply find sendmail and other MTAs too complicated, qmail may be exactly what's called for. Our new guide, qmail, will provide the guidance you need to build an email infrastructure that performs well, makes sense, and is easy to maintain.

This book is the formal proceedings of the Eurographics Workshop on Design, Specifi cation and Verification ofInteractive Systems, DSV-IS'99, which was held at the Uni versity of Minho, Braga, Portugal from June 2 to June 4, 1999. The previous events of this series were held at Pisa, Toulouse, Namur, Granada, and Abingdon; the theme this year was "Engaging the Mind by Enriching the Senses," emphasising the importance of the interface in making interaction both effective and enjoyable. Presentations and discussions covered topics that included specification methods and their use in design, model-based tool support, task and dialogue models, distributed col laboration, and models for VR input. As in previous years, there was a strong emphasis on formal representations and modelling techniques, and their use in understanding in teraction and informing the design of artefacts. However, the aim of the workshop is to encourage an exchange of views within a broad community, and other approaches, in particular tool support for model-based design, were also represented. This book includes the papers of the two invited speakers (one as an abstract only), the fourteen full papers accepted for publication, two shorter position papers, and the reports from the working group discussions. The format of the workshop aimed to mix formal paper presentations with informal discussion sessions, with the two invited talks setting the tone for the meeting."
