Book description

Network Troubleshooting Tools helps you sort through the thousands of tools that have been developed for debugging TCP/IP networks and choose the ones that are best for your needs. It also shows you how to approach network troubleshooting using these tools, how to document your network so you know how it behaves under normal conditions, and how to think about problems when they arise so you can solve them more effectively.
Full Description

Over the years, thousands of tools have been developed for debugging TCP/IP networks. They range from very specialized tools that do one particular task, to generalized suites that do just about everything except replace bad Ethernet cables. Even better, many of them are absolutely free. There's only one problem: who has time to track them all down, sort through them for the best ones for a particular purpose, or figure out how to use them? Network Troubleshooting Tools does the work for you--by describing the best of the freely available tools for debugging and troubleshooting. You can start with a lesser-known version of ping that diagnoses connectivity problems, or take on a much more comprehensive program like MRTG for graphing traffic through network interfaces. There's tkined for mapping and automatically monitoring networks, and Ethereal for capturing packets and debugging low-level problems. This book isn't just about the tools available for troubleshooting common network problems. It also outlines a systematic approach to network troubleshooting: how to document your network so you know how it behaves under normal conditions, and how to think about problems when they arise, so you can solve them more effectively. The topics covered in this book include:
  • Understanding your network
  • Connectivity testing
  • Evaluating the path between two network nodes
  • Tools for capturing packets
  • Tools for network discovery and mapping
  • Tools for working with SNMP
  • Performance monitoring
  • Testing application layer protocols
  • Software sources
If you're involved with network operations, this book will save you time, money, and needless experimentation.

"The information is well organized, easy to find, and well presented; over and above that, the book is a good read. Anyone interested in getting an insight into how TCP/IP Networks tick should read it."
--Major Keary, PC Update Nov 2002

"'Network Troubleshooting Tools' is a good primer for administrators who are working or interested in highly networked environments. It does a fine job of providing administrators and system programmers with a toolkit and methodology for troubleshooting connectivity related issues. This is a good well-rounded text. It covers simple things, such as how ping and traceroute work, to more complex tasks, such as using nemesis and hping to test firewalls with hand-crafted packets...certainly recommend Network Troubleshooting Tools for all but the most experienced system and network administrators. If you are less than a genius, there is something in it for you."
--Dengue, OpenBSD Journal

"If you're new to network admin, have inherited a network or are switching from one OS to another, this book will definitely come in very useful. Not only about pure problem solving, chapters on discovery, analysis and documentation round out a comprehensive book that discusses near my estimation, over 100 tools."
--Helen McManus, linuxchix.org

"an excellent collection of the best freely available tools for debugging and troubleshooting computer networks...If you are involved with computer network operations, this book will save you time, money, and needless experimentation?an invaluable tool for anyone currently administering a computer network. As is usually the case with all O'Reilly works, very busy systems administrators will find the attention to detail and the superbly organized material very helpful as they attempt to integrate the valuable information in this book in their daily work."
--Dale Farris, Golden Triangle PC Club, Feb 2002

"We highly recommend it for ay sysadmin bookshelf."
--Netsurfer Digest, Jan 24, 2002

"a truly useful and enlightening programming resource...a well-organized, comprehensive, readable work...Simply stated, O'Reilly has the best typography, page design, and graphical conventions in the industry."
--Mark Cyzyk, ColdFusion Developer's Journal, Jan 2002

"Must read!!!"
--Today's Books, Jan 28, 2002

"Sloan's 'Tools' is another neat book from O'Reilly. I especially liked his tool approach (after all, that's what I consider one of the most important and distinctive features of Unix). His list of tools and sources--from Analyzer and Argus through MRTG and nemesis to xplot and xv--is simply superb...one of the Top Ten Books for 2001."
--Peter H. Slaus; login: Dec 2001

"'Network Troubleshooting Tools' gets full marks for content. Of itself, content can be of little value if disorganized or poorly presented. In this instance the information is well organized, easy to find, and well presented; over and above that, the book is a good read. Anyone interested in getting an insight into how TCP/IP networks tick should read it-- one doesn't need a technical background. 'Network Troubleshooting Tools' should be on every network administrators bookshelf."
--Major Keary, Book News, Dec 2001

"an excellent collection of the best of the freely available tools for debugging and troubleshooting computer networks. If you are involved with computer network operations, this book will save you time, money and needless experimentation. O'Reilly Hits Another Homer. The O'Reilly publishing firm, famous for their emphasis on a common-sense approach to explaining very technical material, depth of detail, and focus on the practical, has released an invaluable tool for anyone currently administering a computer network. As is usually the case with all O'Reilly works, very busy systems administrators will find the attention to detail and the superbly organized material very helpful as they attempt to integrate the valuable information in this book in their daily work."
--Dale Farris, Golden Triangle PC Club, Sept 2001
