[expert] netflow-like tool under linux???

[jose orlando t. ribeiro]

Hi!

there is some network tool like Cisco's Netflow for Linux?

I want to do some network shaping at work but I don't have Netflow at my 
department and I don't know any tool like that for Linux (or any other 
OS, to be sincere)... we did some experiences enabling Netflow packets 
in our routers and collected some data, but we are short of ideas how to 
treat it in a pratical manner... so I'm looking for a ready-made option...

TIA
