Linux Device Drivers, 3rd Edition
by Jonathan Corbet
from O'Reilly Media, Inc.
Updated to cover version 2.4.x of the Linux kernel, the second edition of Linux Device Drivers remains the best general-purpose, paper-bound guide for programmers wishing to make hardware devices work under the world's most popular open-source operating system. The authors take care to show how to write drivers that are portable--that is, that compile and run under all popular Linux platforms. That, along with the fact that they're careful to explain and illustrate concepts, makes this book very well suited to any programmer familiar with C but not with the hardware-software interface. It's worth noting that the emphasis in the title is on "device drivers" as much as "Linux." This book will make sense to you if you've never written a driver for any platform before. It helps if you have some Linux or Unix background, but even that is secondary as a prerequisite to C skill.
For a programming text--and one concerned with low-level instructions and data structures, at that--this book is remarkably rich in prose. You'll typically want to read this book straight through, more or less skipping the code samples, before sketching out your plan for the driver you need to write. Then, go back and pay closer attention to the sections on specific details you need to implement, like custom task queues. For coding-time details about specific system calls and programming techniques, count on the index to point you to the right passages. --David Wall
Topics covered: Techniques for writing hardware device drivers that run under Linux kernels 2.0.x through 2.2.x. Sections show how to manage memory, time, interrupts, ports, and other details of the hardware-software interface.
Device drivers literally drive everything you're interested in--disks, monitors, keyboards, modems--everything outside the computer chip and memory. And writing device drivers is one of the few areas of programming for the Linux operating system that calls for unique, Linux-specific knowledge. For years now, programmers have relied on the classic "Linux Device Drivers" from O'Reilly to master this critical subject. Now in its third edition, this bestselling guide provides all the information you'll need to write drivers for a wide range of devices.
Over the years the book has helped countless programmers learn:
how to support computer peripherals under the Linux operating system
how to develop and write software for new hardware under Linux
the basics of Linux operation even if they are not expecting to write a driver
The new edition of "Linux Device Drivers" is better than ever. The book covers all the significant changes to Version 2.6 of the Linux kernel, which simplifies many activities, and contains subtle new features that can make a driver both more efficient and more flexible. Readers will find new chapters on important types of drivers not covered previously, such as consoles, USB drivers, and more.
Best of all, you don't have to be a kernel hacker to understand and enjoy this book. All you need is an understanding of the C programming language and some background in Unix system calls. And for maximum ease-of-use, the book uses full-featured examples that you can compile and run without special hardware.
Today Linux holds fast as the most rapidly growing segment of the computer market and continues to win over enthusiastic adherents in many applicationareas. With this increasing support, Linux is now absolutely mainstream, and viewed as a solid platform for embedded systems. If you're writing device drivers, you'll want this book. In fact, you'll wonder how drivers are ever written without it.

from Course Technology
Linux+ Guide to Linux Certification, Second Edition offers the most up-to-date information which empowers students to successfully pass CompTIA's Linux+ Certification exam.
LPI Linux Certification in a Nutshell (In a Nutshell (O'Reilly))
by Steven Pritchard
from O'Reilly Media, Inc.
You may not have heard of the Linux Professional Institute (LPI) or its professional certifications, but they're becoming an important part of proving professional competence in the Linux operating system. That aside, LPI Linux Certification in a Nutshell is a fantastic introductory Linux book, well suited to introducing a curious newcomer to the environment and bringing an intermediate user up to expert status.
The book is organized around the LPI's published standards for two Level 1 exams (exams 101, which deals with key commands and file-system concepts, and 102, which places more emphasis on hardware, networking, and shell scripting). The organization works well even if you're not specifically preparing for either exam.
LPI Linux Certification in a Nutshell assumes nothing in early chapters, going so far--to cite one example--as to walk readers through the concept of commands with parameters separately from the concept of commands alone. Later, the pace picks up, and strategic advice is substituted (such as how to partition a disk for maximum speed and reliability) for "type-this" instructions.
Throughout, the book makes effective use of O'Reilly's time-tested and remarkably clear format for presenting Unix commands and configuration files. Each chapter concludes with a series of exercises designed to help you discover behaviors on your own, and includes the practice questions you expect in a test-prep aid. --David Wall
Topics covered: The knowledge that's tested on the Linux Professional Institute's exams 101 and 102, which includes everything from basic Linux commands and concepts to installation of the operating system, essential network configuration, and kernel recompilation.
"LPI Linux Certification in a Nutshell," Second Edition is an invaluable resource for determining what you need to practice to pass the Linux Professional Institute exams. This book will help you determine when you're ready to take the exams, which are technically challenging and designed to reflect the skills that administrators need in real working environments.
As more corporations adopt Linux as the networking backbone for their IT systems, the demand for certified technicians will become even greater. Passing the LPI exams will broaden your career options because the LPIC is the most widely known and respected Linux certification program in the world. "Linux Journal" recognized the LPI as the best Training and Certification Program. The exams were developed by the Linux Professional Institute, an international, volunteer-driven organization with affiliates in a dozen countries.
The core LPI exams cover two levels. Level 1 tests a basic knowledge of Linux installation, configuration, and command-line skills. Level 2 goes into much more depth regarding system troubleshooting and network services such as email and the Web. The second edition of "LPI Linux Certification in a Nutshell" is a thoroughly researched reference to these exams. The book is divided into four parts, one for each of the LPI exams. Each part features not only a summary of the core skills you need, but sample exercises and test questions, along with helpful hints to let you focus your energies.
Major topics include: GNU and Unix commands Linux installation and package management Devices, filesystems, and kernel configuration Text editing, processing, and printing The X Window System Networkingfundamentals and troubleshooting Security, including intrusion detection, SSH, Kerberos, and more DNS, DHCP, file sharing, and other networking infrastructure Email, FTP, and Web services
Praise for the first edition:
""Although O'Reilly's Nutshell series are intended as 'Desktop Reference' manuals, I have to recommend this one as a good all-round read; not only as a primer for LPI certification, but as an excellent introductory text on GNU/Linux. In all, this is a valuable addition to O'Reilly's already packed stable of Linux titles and I look forward to more from the author."" --First Monday

Understanding Linux Network Internals
by Christian Benvenuti
from O'Reilly Media, Inc.
If you've ever wondered how Linux carries out the complicated tasks assigned to it by the IP protocols -- or if you just want to learn about modern networking through real-life examples -- "Understanding Linux Network Internals" is for you.
Like the popular O'Reilly book, "Understanding the Linux Kernel," this book clearly explains the underlying concepts and teaches you how to follow the actual C code that implements it. Although some background in the TCP/IP protocols is helpful, you can learn a great deal from this text about the protocols themselves and their uses. And if you already have a base knowledge of C, you can use the book's code walkthroughs to figure out exactly what this sophisticated part of the Linux kernel is doing.
Part of the difficulty in understanding networks -- and implementing them -- is that the tasks are broken up and performed at many different times by different pieces of code. One of the strengths of this book is to integrate the pieces and reveal the relationships between far-flung functions and data structures. "Understanding Linux Network Internals" is both a big-picture discussion and a no-nonsense guide to the details of Linux networking. Topics include:
Key problems with networking
Network interface card (NIC) device drivers
System initialization
Layer 2 (link-layer) tasks and implementation
Layer 3 (IPv4) tasks and implementation
Neighbor infrastructure and protocols (ARP)
Bridging
Routing
ICMP
Author Christian Benvenuti, an operating system designer specializing in networking, explains much more than how Linux code works. He shows the purposes of major networking features and the trade-offs involved inchoosing one solution over another. A large number of flowcharts and other diagrams enhance the book's understandability.
