As in earlier Addison-Wesley books on the UNIX-based BSD operating system, Kirk McKusick and George Neville-Neil deliver here the most comprehensive, up-to-date, and authoritative technical information on the internal structure of open source FreeBSD. Readers involved in technical and sales support can learn the capabilities and limitations of the system; applications developers can learn effectively and efficiently how to interface to the system; system administrators can learn how to maintain, tune, and configure the system; and systems programmers can learn how to extend, enhance, and interface to the system. The authors provide a concise overview of FreeBSD's design and implementation. Then, while explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing the systems facilities. As a result, readers can use this book as both a practical reference and an in-depth study of a contemporary, portable, open source operating system.This book: *Details the many performance improvements in the virtual memory system *Describes the new symmetric multiprocessor support *Includes new sections on threads and their scheduling *Introduces the new jail facility to ease the hosting of multiple domains *Updates information on networking and interprocess communication Already widely used for Internet services and firewalls, high-availability servers, and general timesharing systems, the lean quality of FreeBSD also suits the growing area of embedded systems. Unlike Linux, FreeBSD does not require users to publicize any changes they make to the source code.

The most difficult part of building a server with FreeBSD, the Unix-like operating system, is arguably software installation and configuration. Finding the software is easy enough; getting everything up and running is another thing entirely. The only option for many people has been to hire a consultant.Building a Server with FreeBSD 7 is for those of us who prefer to build our own server. If you're a small business owner looking for a reliable email server, a curious Windows administrator, or if you just want to put that old computer in the closet to work, you'll learn how to get things up and running quickly. Then, once you have a working system, you can experiment, extend, and customize as you please.
You'll learn how to install FreeBSD, then how to install popular server applications with the ports collection. Each package is treated as an independent module, so you can dip into the book at any point to install just the packages you need, when you need them. The book s modules cover topics like:
- Running common FreeBSD admin commands and tasks
- Managing the FreeBSD ports collection
- Installing third-party apps like Apache, Courier-IMAP, SpamAssassin, CUPS, Cyrus SASL, MediaWiki, and WordPress
- Setting up MySQL, NTP, ISC DHCP, ISC BIND DNS, PHP, OpenLDAP, OpenSSH, OpenSSL, and OpenVPN
Building a Server with FreeBSD 7 will have you up and running fast, with minimum hassle. (Just be sure to send the money you save to the Unemployed Consultant Foundation.)

For over seven years, computer networking and security instructor and consultant, Dru Lavigne, meticulously documented her learning experiences with FreeBSD administration and open source software usage in a series of over 110 articles. Many readers praised and recommended the author's informative tutorials. The Best of FreeBSD Basics book contains most of these articles - updated to reflect the usage on FreeBSD 6.2. The Best of FreeBSD Basics provides practical advice for completing common tasks on FreeBSD and is a great way to get to know FreeBSD - and Unix in general. Darwin, DragonFly, Linux, Mac OS X, NetBSD, and OpenBSD fans will also find a lot of the book invaluable and useful. Covering a huge range of FreeBSD and open source topics, The Best of FreeBSD Basics includes step-by-step directions, things to watch out for, and hints for success. A sampling of the book's topics include installing an X11 server and setting up a desktop environment, comparing common tasks with Linux, playing audio and video files, user administration, system startup, finding and using documentation, managing backups, networking basics, IPsec, setting up several servers, filtering spam, improving security, enabling firewalls, and a lot more.

FreeBSD is by far the most popular version of BSD®, the legendary operating system that has contributed a great deal to every version of Unix® in use today (including Mac OS® X). Originally a community effort by the University of California at Berkeley, FreeBSD was aimed at making Unix a little friendlier and easier to use. By the time other free operating systems came along, BSD was firmly established and very reliable. And it continues to be today. For seven years, the FreeBSD community has relied on Greg Lehey's classic, The Complete FreeBSD, to guide them through its configuration and administration. The 4th edition, covering version 5 of FreeBSD, is now available through O'Reilly Community Press. The Complete FreeBSD is an eminently practical guidebook that explains not only how to get a computer up and running with the FreeBSD operating system, but also how to turn it into a highly functional and secure server that can host large numbers of users and disks, support remote access, and provide web service, mail service, and other key parts of the Internet infrastructure. The book provides in-depth information on installation and updates, back-ups, printers, RAID, various Internet services, firewalls, the graphical X Window system, and much more. Author Greg Lehey is a member of the FreeBSD core team and has been developing, documenting, and advocating for FreeBSD for nearly ten years. Whether you're an experienced Unix user or just interested in learning more about this free operating system and how you can put it to work for you, this do-it-yourself BSD documentation will provide the information you need. The Complete FreeBSD is the second release in the O'Reilly Community Press Series. Unlike classic O'Reilly animal books, which are created to fill an information void, the Community Press titles provide convenient printed copies of documentation that is already available online. O'Reilly's role in the series is limited to providing manufacturing and distribution services rather than editorial development, so that each Community Press title reflects the editorial voice and organization of the community that has created it.

Though rootkits have a fairly negative image, they can be used for both good and evil. Designing BSD Rootkits arms you with the knowledge you need to write offensive rootkits, to defend against malicious ones, and to explore the FreeBSD kernel and operating system in the process.Organized as a tutorial, Designing BSD Rootkits will teach you the fundamentals of programming and developing rootkits under the FreeBSD operating system. Author Joseph Kong's goal is to make you smarter, not to teach you how to write exploits or launch attacks. You'll learn how to maintain root access long after gaining access to a computer and how to hack FreeBSD.
Kongs liberal use of examples assumes no prior kernel-hacking experience but doesn't water down the information. All code is thoroughly described and analyzed, and each chapter contains at least one real-world application.
Included:
- The fundamentals of FreeBSD kernel module programming
- Using call hooking to subvert the FreeBSD kernel
- Directly manipulating the objects the kernel depends upon for its internal record-keeping
- Patching kernel code resident in main memory; in other words, altering the kernel's logic while it's still running
- How to defend against the attacks described
Hack the FreeBSD kernel for yourself!

This is a revised version of this volume. Changes in this edition include: Code has been updated to use ANSI C and the UNIX operating systems (POSIX). Covers SLIP connections (a popular program that allows TCP/IP access to the Internet over dial-up phone systems. Latest changes in Network File System protocol (NFS3). This edition focuses on the BSD version of UNIX. This volume answers the question “How does one use TCP/IP?” — focusing on the client-server paradigm, and examining algorithms for both the client and server components of a distributed program. Describes the AT&T TLI interface and uses it in all examples. The principles underlying distributed programs and all server designs are emphasized. Thoroughly covers the many ways to design interactive and concurrent client and server software, as well as their proper use and application. Concepts apply to Client-Server programs in general; not just TCP/IP. Any communications professional who wants to put TCP/IP to use. This is everyone working on Internet communications.

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

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.

The FreeBSD Corporate Networker's Guide is written for the beginning FreeBSD administrator who wants to take advantage of the power and cost savings afforded by use of this operating system on their organization's production network. FreeBSD is a UNIX-like operating system that takes its name from the Berkeley Software Distribution group. FreeBSD is a direct descendent of the original BSD UNIX code that the Computing Science Research Group of the University of California, Berkeley, released. That code was used as a base for many other commercial UNIX systems, such as early HP/UX and Sun's SunOS 4.1.XIn keeping with the spirit of freely available Open Source software, this book has operating with the Microsoft (MS) operating system and Microsoft networking as a primary goal. Use of FreeBSD to solve problems in a corporate network environment is emphasized.
Basing an organizational production network on standards-based methods and protocols such as TCP/IP, is important as it permits you to mix and match FreeBSD and Windows servers and clients as you see fit. Using FreeBSD and Windows on the same network is an excellent way to do this.
The first section of this book, Chapters 1 through 3, covers preinstallation and installation of FreeBSD. Chapters 4 through 9 are intended to be taken piecemeal. Do you need a FreeBSD router to connect to the Internet? If so, skip to Chapter 5. Do you need a FreeBSD mailserver? If so, skip to Chapter 9. Although there is some order, in that later topics do build on some material introduced in earlier chapters, the main idea is to concentrate first on the sections for which you have an immediate need. Chapter 10, Advocacy, contains material that polarized the reviewers. Some loved it, some hated it; nobody lacked an opinion about it. This chapter presents all the reasons to use FreeBSD instead of Windows, and it includes some background information about FreeBSD.
The book includes a CD of the Release version of FreeBSD 4.2, this is the same CD as used in CD#1 of the 4-CD set of FreeBSD 4.2 published by BSD Inc./Walnut Creek. There is also a companion website that the Author maintains specifically for this book.

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

BSD Sockets Programming from a Multi-Language Perspective is written for software developers who need to create a variety of network applications. It begins by detailing the efficient and effective uses of the BSD Sockets API for networked application development in multiple languages. From there the BSD API is covered in detail and the purpose of each function and socket option is identified, including the advanced behavioral side-effects of each. Having a thorough understanding of these issues and techniques is often the difference between being a novice and professional network application developer. Optimizing networked applications and avoiding common pitfalls are also addressed. After the solid foundational coverage of the Sockets API in Part I, Part II investigates it from a variety of language perspectives. Using six different languages in all, including imperative languages (C), object-oriented languages (Java), and scripting languages (Perl), you learn the advantages and disadvantages of each language as they relate to the development of networked applications and the Sockets API. Finally, in Part III, a set of software patterns is discussed for each language. Patterns include a simple HTTP server and SMTP client, and various Sockets communication styles (stream, datagram, multicast, and broadcast). These patterns can be used as the basis for more complex applications or to give you a quick-start when building networked applications. The patterns also illuminate the differences between the network APIs for each language and identify how certain languages make patterns simple and others make them complex. The accompanying CD-ROM includes all of the source code from the book, including the patterns detailed in Part III, as well as open source interpreters and other tools.
