When you're paying for bandwidth, you want to make sure that it's efficiently used -- which is why tools like dsniff are so valuable. In this tutorial, Duane Dunston explains how to implement dsniff and why it's important to monitor network traffic:
This is a practical step by step guide showing how to use Dsniff, MRTG, IP Flow Meter, Tcpdump, NTOP, and Ngrep, and others. It also provides a discussion of how and why we should monitor network traffic.
In order to properly understand how your network operates and to debug any problems with network congestion, and other network issues, network monitoring is essential. It helps to quickly find out if your local network is having a problem, a particular host, or if some hosts are using up an excessive amount of bandwidth. It can also be used to just provide a historical analysis of how the network is being used.
