Are you interested in getting URL information from NetFlow?  The nProbe NetFlow probe or the nBox can do it.  Paul at Plixer International recently wrote a blog on Recommended nProbe Templates.  For a foundation on this topic, check out his blog.  As an extension of his blog, I’ll explain how to get URLS from the nProbe.

Below we see the filter on the left for the domain and the URL filter. Host is our culprit.

What other URLs is this host visiting?  Just click it to find out!  nProbe and Scrutinizer make network traffic analysis that simple!
