I can say that before I submitted this article, I sent it to two different people on two different networks to review and follow. It worked for them.

Netflow setup is a complete nightmare. Perhaps it worked more smoothly back when these tools were new, I don't know. Getting cflow.pm working is the worst part by far. Flowdumper is just the simplest front end and test for cflow.pm.

I know of people working on new flow capturing tools, but they're not ready yet. :-(
