From the Back Cover
Discover how to solve real-world system administration problems with this collection of end-to-end shell scripts

This comprehensive book takes you step-by-step through the process of writing shell scripts to solve real-world Unix problems and tasks. Each chapter begins by presenting a typical Unix challenge that you'll most likely experience at your job. With each challenge, you'll learn how to identify a specific goal and start the shell script by defining the correct command syntax to solve the problem. You'll find out how to build the shell script around the commands, filter the commands output to strip out the unneeded data, and add options that give users more flexibility on the command line.

The approach used will teach you how to attack problems logically. It will also empower you to take the basic command syntax and turn it into a shell scripting solution.

Throughout the book, you'll find end-to-end shell scripts that you can use to automate repetitive tasks and solve real-world system administration problems. These tasks include:
* Communications such as automated event notification, monitoring processes locally and on remote systems, and automated FTP file transfers
* Information gathering and monitoring for file systems, paging/swap space, system load, applications, processes, and capturing the system's configuration
* Print queue management to keep the printers printing
* Floating point mathematics in shell scripts using the bc utility

The companion Web site contains all of the shell scripts and most of the functions that are discussed in the book as well as bonus shell scripts for various tasks.

In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow disks.

The third edition of "Understanding the Linux Kernel" takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the book covers more than just the functioning of the code; it explains the theoretical underpinnings of why Linux does things the way it does.

This edition of the book covers Version 2.6, which has seen significant changes to nearly every kernel subsystem, particularly in the areas of memory management and block devices. The book focuses on the following topics:

Memory management, including file buffering, process swapping, and Direct memory Access (DMA)

The Virtual Filesystem layer and the Second and Third Extended Filesystems

Process creation and scheduling

Signals, interrupts, and the essential interfaces to device drivers

Timing

Synchronization within the kernel

Interprocess Communication (IPC)

Program execution

"Understanding the Linux Kernel" will acquaint you with all the inner workings of Linux, but it's more than just an academic exercise. You'll learn what conditions bring out Linux's best performance, and you'll see how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments. This book will help you make the most of your Linux system.

About the Author
Daniel P. Bovet got a Ph.D. in computer science at UCLA in 1968 and is now full Professor at the University of Rome, "Tor Vergata," Italy. He had to wait over 25 years before being able to teach an operating system course in a proper manner because of the lack of source code for modern, well-designed systems. Now, thanks to cheap PCs and to Linux, Marco and Dan are able to cover all the facets of an operating system from booting to tuning and are able to hand out tough, satisfying homework to their students. (These young guys working at home on their PCs are really spoiled; they never had to fight with punched cards.) In fact, Dan was so fascinated by the accomplishments of Linus Torvalds and his followers that he spent the last few years trying to unravel some of Linux's mysteries. It seemed natural, after all that work, to write a book about what he found. Marco Cesati received a degree in mathematics in 1992 and a Ph.D. in computer science (University of Rome, "La Sapienza") in 1995. He is now a research assistant in the computer science department of the School of Engineering (University of Rome, "Tor Vergata"). In the past, he served as system administrator and Unix programmer for the university (as a Ph.D. student) and for several institutions (as a consultant).

Design, build, and operate integrated gateway routing systems

• Learn how to design, build, and administer integrated gateway routing systems
• Identify the advantages and disadvantages of Cisco/UNIX integrated designs
• Review lab exercises throughout the book that bring concepts to life
• Encounter the fascinating world of dynamic UNIX routing and TCP/IP stacks
• Understand the way forwarding and signaling are implemented in the UNIX world
• Gain proficiency with tunnels and VPNs
• Utilize advanced features such as high availability, NAT, bandwidth management, policy routing, and multicast architectures
• Explore Linux and BSD networking concepts

UNIX gateways introduce massive performance possibilities at a fraction of the price of dedicated proprietary appliances by performing network tasks entirely in software. With Cisco Systems routers dominating the Internet and enterprise networking and UNIX routing and gateway solutions spreading from within server farms and data centers, new opportunities and possibilities arise for system and network administrators who understand the benefit of integrated designs. For example, the use of UNIX gateways can enable intrusion detection, firewalling, cable and DSL access, terminal servers and access concentrators, VPNs, roaming user support, and other LAN and WAN services. Far from being mutually exclusive, Cisco devices, UNIX operating systems, and open source applications can enjoy a peaceful, perhaps even inevitable, coexistence for years to come. Integrated Cisco and UNIX Network Architectures shows how Cisco routers, switches, and firewalls seamlessly work together with UNIX operating systems in an integrated networking and security environment.

Integrated Cisco and UNIX Network Architectures reveals not just the feasibility but also the desirability of Cisco/UNIX integrated routing with regard to systems integration, interoperability, and feature requirements. Detailed, progressively complex lab scenarios emphasize enterprise and ISP requirements, casting light on the similarities and differences of these two worlds. Platform issues, such as behavior of firewall filters, kernel features, and proper standards compliance, are discussed, analyzed with sniffers, and tested with handcrafted traffic from packet generators and test applications.

If you want to master and maximize the operation of your UNIX and Cisco network architectures, this book shows you how.

This book is part of the Networking Technology Series from Cisco Press¿ which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

Amazon.com Review
Part basic primer, part reference guide, this slim volume will make your life with UNIX much simpler. This book is specifically designed for those who are new to UNIX and contains neither introductory-level condescension nor advanced-level gibberish. Well-indexed and clearly mapped, Learning the UNIX Operating System will show you how to use and manage files and get your e-mail as well as how to perform more advanced tasks, such as redirecting standard input/output and multitasking your processes. Those new to the UNIX world will appreciate its concise presentation, and those reasonably familiar with UNIX will learn many new shortcuts, tricks, and tools. --Jennifer Buckendorff 

Review
'Ah, what a lovely little book. My list of classics include: K&R, Pike and Kernighan's The Practice of Programming, their The Unix Programming Environment, The Perl Cookbook and The Awk Programming Language. To that list I can now add the current volume. What more can I say: this is a good buy, especially for anyone approaching Unix/Linux for the first time. Even older hands might find it useful to have a copy, if only to give away. It won't provide all that is needed but it is good starting point. I am convinced that computers are getting uglier by the day. This ugliness stems from a quest for glitz at the expense of simplicity and elegance. Like a breath of fresh air, 'Learning the Unix Operating System' is a reminder that it doesn't need to be that way. ' - Joe McCool,
