Visualizing Network Traffic with Netflow and FlowScan

My previous article explained how to gather session-level network information with Netflow. This article shows how to convert all that nifty data into pretty multicolored pictures on a web server. If you found this article by a web search, you really do need to read the previous article. I will discuss the details of flowscan as appropriate for the setup discussed in that article; if you are not using softflowd and flow-tools to collect your flows, and if you don't have Cflow.pm properly installed, this may or may not work for you.
