Book 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.

Book Description
Today's rapidly changing technology offers increasingly complex challenges to the network administrator, MIS director and others who are responsible for the overall health of the network. This Network Maintenance and Troubleshooting Guide picks up where other network manuals and texts leave off. It addresses the areas of how to anticipate and prevent problems, how to solve problems, how to operate a healthy network and how to troubleshoot. Network Maintenance and Troubleshooting Guide also provides basic technical and troubleshooting information about cable testing, Ethernet and Token Ring networks and additional information about Novell's IPX(R) protocol and TCP/IP. Examples are shown as either diagrams and tables, or screen captures from Fluke instruments. Network professionals will appreciate the guide's "real world" orientation toward solving network crises quickly, by guiding readers to solutions for restoration of end to end data delivery as quickly as possible. The network novice will learn from the simplified descriptions about networking technology in the Appendices.

Book Description
Nowadays, the Internet is becoming more and more complex due to an everincreasing number of network devices, various multimedia services and a prevalence of encrypted traffic. Therefore, in this context, this book presents a novel efficient multi modular troubleshooting architecture to overcome limitations related to encrypted traffic and high time complexity. This architecture contains five main modules: data collection, anomaly detection, temporary remediation, root cause analysis and definitive remediation. In data collection, there are two sub modules: parameter measurement and traffic classification. This architecture is implemented and validated in a software-defined networking (SDN) environment.

In doing so he exposes the reality of monopoly capitalism in its contemporary global form.In a bravura conclusion, Amin argues that the current capitalist system is not viable and that implosion is unavoidable. The Implosion of Capitalism makes clear the stark choices facing humanity - and the urgent need for a more humane global order.
