Welcome to Ubuntu 7.10 Linux Unleashed! This book covers the free Linux distribution named Ubuntu and includes a fully functional and complete operating system produced by the Ubuntu Community, sponsored by Canonical Software.

Ubuntu directly descends from one of the oldest and most revered Linux distributions ever: Debian. Those of you who know nothing about Linux will likely not have heard of Debian; it is enough to know that it is considered to be one of the most stable and secure Linux distributions currently available. Ubuntu benefits directly from many contributions from free software developers across the world.

If you are new to Linux, you have made a great decision by choosing this book. Sams Publishing’s Unleashed books offer an in-depth look at their subject, taking in both beginner and advanced users and moving them to a new level of knowledge and expertise. Ubuntu is a fast-changing distribution that can be updated at least twice a year. We have tracked the development of Ubuntu from early on to make sure that the information in this book mirrors closely the development of the distribution. A full copy of Ubuntu is included on the enclosed disc, making it possible for you to install Linux in less than an hour! No longer an upstart, Linux now has an enviable position in today’s modern computing world. It can be found on machines as diverse as mobile phones and wristwatches, all the way up to supercomputers—in fact, Linux currently runs on more than half of the world’s top 500 supercomputers.

Do not let the reputation of Linux discourage you, however. Most people who have heard of Linux think that it is found only on servers, looking after websites and email. Nothing could be further from the truth because Linux is making huge inroads in to the desktop market, too. Corporations are realizing the benefits of running a stable and powerful operating system that is easy to maintain and easy to secure. Add to that the hundreds of improvements in usability, and Linux becomes an attractive proposition that tempts many CIOs. The best part is that as large Linux vendors improve Linux, the majority of those improvements make it into freely available distributions, allowing you to benefit from the additions and refinements made. You can put Ubuntu to work today and be assured of a great user experience.

This book provides all the information that you need to get up and running with Ubuntu. It even tells you how to keep Ubuntu running in top shape and how to adapt Ubuntu to changes in your own needs. You can use Ubuntu at home, in the workplace, or, with permission, at your school or college. In fact, you might want to poke around your school’s computer rooms: You will probably find that someone has already beaten you to the punch—Linux is commonly found in academic institutions. Feel free to make as many copies of the software as you want; because Ubuntu is freely distributable all over the world, no copyright lawyers are going to pound on your door.

Wouldn’t you like to automate the tedious daily tasks of system administration? Automating UNIX and Linux Administration will show you how, by exploring existing tools and offering real-world examples. Parts of the book are Linux-specific, but most of it applies to a UNIX system, including multiple variants of UNIX. Author Kirk Bauer briefly overviews tools and technologies—and assumes preliminary knowledge about editing a configuration file or mounting a file system.

The techniques, methods, and tools in this book will help you manage a single system—but will prove especially powerful across multiple systems. No matter if the systems are desktops, servers, or Beowulf clusters—all of them will benefit from this automation. And managing five to five thousand systems will become a simpler task!

The Ubuntu distribution simplifies Linux by providing a sensible collection of applications, an easy-to-use package manager, and lots of fine-tuning, which make it possibly the best Linux for desktops and laptops. Readers of both Linux Journal and TUX Magazine confirmed this by voting Ubuntu as the best Linux distribution in each publication's 2005 Readers Choice Awards. None of that simplification, however, makes Ubuntu any less fun if you're a hacker or a power user.

Like all books in the "Hacks" series,Ubuntu Hacks includes 100 quick tips and tricks for all users of all technical levels. Beginners will appreciate the installation advice and tips on getting the most out of the free applications packaged with Ubuntu, while intermediate and advanced readers will learn the ins-and-outs of power management, wireless roaming, 3D video acceleration, server configuration, and much more.

This book is a guide to FreeBSD for network administrators; therefore it does not cover basic installation and configuration of FreeBSD, but is about using FreeBSD to build, secure, and maintain networks. After introducing the basic tools for monitoring the performance and security of the system the book moves on to cover using jails-FreeBSD virtual environments-to secure your network. Then it shows how to overcome the different bottlenecks that you may meet depending on the services you are running by tweaking different parameters to maintain a high performance from your FreeBSD server. Next it covers using the ifconfig utility to configure interfaces with different layer protocols and about connectivity testing and debugging tools. After covering using User PPP or Kernel PPP for Point-to-Point Protocol network configuration it explains basic IP forwarding in FreeBSD and the use of the built-in routing daemons, routed and route6d, which support RIPv1, RIPv2, RIPng, and RDISC. Next it covers the OpenOSPFD and OpenBGPD daemons that you can install to run OSPF and BGP on your host. Then it covers setup and configuration of IPFW and PF, and finally looks at some important internet services and how to set them up on your FreeBSD server

A step-by-step guide to building PHP web sites and applications using the Smarty templating engine
- Bring the benefits of Smarty to your PHP programming
-Give your designers the power to modify content and layout without PHP programming
-Produce code that is easier to debug, maintain, and modify
-Useful for both Smarty developers and users

Smarty is a templating engine for PHP. Designers who are used to working with HTML files can work with Smarty templates, which are HTML files with simple tags while programmers work with the underlying PHP code. The Smarty engine brings the code and templates together. The result of all this is that designers can concentrate on designing, programmers can concentrate on programming, and they don't need to get in each others way so much. Even if you are developing a site on your own, Smarty is a powerful way to make your code clearer to you and others, as well as easier to debug and modify later.

This book is a comprehensive guide to all aspects of using Smarty. It will help you to:
-Install and configure Smarty on your Web server
- Understand how Smarty affects your web site architecture, and build site foundations that make the most of what Smarty offers
- Designers will learn to work with templates that contain variables and logic, to modify layouts or content of Smarty web sites
- See how Smarty caching can improve the performance of your sites
- Develop custom Smarty functions and plug-ins to incorporate into your templates

Using a step-by-step approach based on realistic examples, the expert authors show you how to use Smarty in your own PHP development. The book is ideal for PHP developers who are new to Smarty, and for web designers who are working with PHP developers who are using Smarty.

FreeBSD and OpenBSD are increasingly gaining traction in educational institutions, non-profits, and corporations worldwide because they provide significant security advantages over Linux. Although a lot can be said for the robustness, clean organization, and stability of the BSD operating systems, security is one of the main reasons system administrators use these two platforms.

There are plenty of books to help you get a FreeBSD or OpenBSD system off the ground, and all of them touch on security to some extent, usually dedicating a chapter to the subject. But, as security is commonly named as the key concern for today's system administrators, a single chapter on the subject can't provide the depth of information you need to keep your systems secure.

FreeBSD and OpenBSD are rife with security "building blocks" that you can put to use, and Mastering FreeBSD and OpenBSD Security shows you how. Both operating systems have kernel options and filesystem features that go well beyond traditional Unix permissions and controls. This power and flexibility is valuable, but the colossal range of possibilities need to be tackled one step at a time. This book walks you through the installation of a hardened operating system, the installation and configuration of critical services, and ongoing maintenance of your FreeBSD and OpenBSD systems.

Using an application-specific approach that builds on your existing knowledge, the book provides sound technical information on FreeBSD and Open-BSD security with plenty of real-world examples to help you configure and deploy a secure system. By imparting a solid technical foundation as well as practical know-how, it enables administrators to push their server's security to the next level. Even administrators in other environments--like Linux and Solaris--can find useful paradigms to emulate.

Written by security professionals with two decades of operating system experience, Mastering FreeBSD and OpenBSD Security features broad and deep explanations of how how to secure your most critical systems. Where other books on BSD systems help you achieve functionality, this book will help you more thoroughly secure your deployments.

Like any other software system, Web sites gradually accumulate “cruft” over time. They slow down. Links break. Security and compatibility problems mysteriously appear. New features don’t integrate seamlessly. Things just don’t work as well. In an ideal world, you’d rebuild from scratch. But you can’t: there’s no time or money for that. Fortunately, there’s a solution: You can refactor your Web code using easy, proven techniques, tools, and recipes adapted from the world of software development.

In Refactoring HTML, Elliotte Rusty Harold explains how to use refactoring to improve virtually any Web site or application. Writing for programmers and non-programmers alike, Harold shows how to refactor for better reliability, performance, usability, security, accessibility, compatibility, and even search engine placement. Step by step, he shows how to migrate obsolete code to today’s stable Web standards, including XHTML, CSS, and REST—and eliminate chronic problems like presentation-based markup, stateful applications, and “tag soup.”

The book’s extensive catalog of detailed refactorings and practical “recipes for success” are organized to help you find specific solutions fast, and get maximum benefit for minimum effort. Using this book, you can quickly improve site performance now—and make your site far easier to enhance, maintain, and scale for years to come.
