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.
