The administrator's guide to understanding Linux routing systems and techniques, written by authors with vast experience in implementing network solutions in a variety of operating systems and hardware arenas. The book provides comprehensive, coverage of routing solutions readers can set up on a Linux box, not just a look at what Cisco routers can do.

Summary This classic howto was written in 2002, but it is still a must-read howto for any Linux networking professionals today. Many practical examples are included in the book.It is a very hands−on approach to iproute2, traffic shaping, policy routing and a bit of netfilter.This is a book you should have on your bookshelf.

Benvenuti describes the relationship between the Internet's TCP/IP implementation and the Linux Kernel so that programmers and advanced administrators can modify and fine-tune their network environment.

Will show readers how to work with Cisco IOS 12.x rated routers, or to build a stand alone Linux router .17 - 21% of network servers are currently running Linux, and the Linux share of the market continues to grow. The Linux kernel is the only OS that supports policy routing except for certain versions of Cisco IOS 12.x. Covers policy routing under IPv4 and IPv6. Policy Routing on Linux is an advanced book covering all critical aspects of Linux Policy Routing from the authors extensive experience. It provides documentation and best practice usage for implementing policy routing under Linux with references and comparisons to Cisco IOS policy routing. Readers of this book will be able to: Understand the theory and basic concepts of policy routing; design and install a policy-routed network under IPv4 on a Linux based network using the IP utility for Linux; differentiate between and integrate policy routing structures and dynamic routing protocols; analyse and tune complex policy routed networks on Linux and possibly Cisco networks; and understand the role of policy routing structures and implementations within the Linux IPv6 network stack.

Linux Routers, Second Edition shows you exactly how to reduce your costs and extend your network with Linux-based routing. You'll find step-by-step coverage of software/hardware selection, configuration, management, and troubleshooting for today's key internetworking applications, including LANs, Internet/intranet/extranet routers, Frame Relay, VPNs, remote access, and firewalls. Extensive new coverage includes dynamic routing, Quality of Service, the current Linux kernel - even next-generation IPv6 routing.

This introduction to networking on Linux now covers firewalls, including the use of ipchains and Netfilter, masquerading, and accounting. Other new topics in this second edition include Novell (NCP/IPX) support and INN (news administration).

This soup-to-nuts collection of recipes covers everything you need to know to perform your job as a Linux network administrator, whether you're new to the job or have years of experience. With Linux Networking Cookbook, you'll dive straight into the gnarly hands-on work of building and maintaining a computer network. Running a network doesn't mean you have all the answers. Networking is a complex subject with reams of reference material that's difficult to keep straight, much less remember. If you want a book that lays out the steps for specific tasks, that clearly explains the commands and configurations, and does not tax your patience with endless ramblings and meanderings into theory and obscure RFCs, this is the book for you. You will find recipes for: Building a gateway, firewall, and wireless access point on a Linux network Building a VoIP server with Asterisk Secure remote administration with SSH Building secure VPNs with OpenVPN, and a Linux PPTP VPN server Single sign-on with Samba for mixed Linux/Windows LANs Centralized network directory with OpenLDAP Network monitoring with Nagios or MRTG Getting acquainted with IPv6 Setting up hands-free networks installations of new systems Linux system administration via serial console And a lot more. Each recipe includes a clear, hands-on solution with tested code, plus a discussion on why it works. When you need to solve a network problem without delay, and don't have the time or patience to comb through reference books or the Web for answers, Linux Networking Cookbook gives you exactly what you need.

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 in choosing one solution over another. A large number of flowcharts and other diagrams enhance the book's understandability.

“As an author, editor, and publisher, I never paid much attention to the competition—except in a few cases. This is one of those cases. The UNIX System Administration Handbook is one of the few books we ever measured ourselves against.” —Tim O’Reilly, founder of O’Reilly Media “This edition is for those whose systems live in the cloud or in virtualized data centers; those whose administrative work largely takes the form of automation and configuration source code; those who collaborate closely with developers, network engineers, compliance officers, and all the other worker bees who inhabit the modern hive.” —Paul Vixie, Internet Hall of Fame-recognized innovator and founder of ISC and Farsight Security “This book is fun and functional as a desktop reference. If you use UNIX and Linux systems, you need this book in your short-reach library. It covers a bit of the systems’ history but doesn’t bloviate. It’s just straight-forward information delivered in a colorful and memorable fashion.” —Jason A.
