Dennis,

You might try FlowViewer https://sourceforge.net/projects/flowviewer

Fairly easy Linux install over top of SiLK, netflow capture and analysis software from Carnegie-Mellon. SiLK is very robust and FlowViewer provides a web-based interface with extensive analysis, graphing and tracking tools. Filtering includes by AS. You can create an MRTG-like set of long-term graphs for each AS and as a group of top 10 ASes (Last 24 Hours, 7 Days, 4 Weeks, 3 Years.)

Best,

Joe

I am looking for a free program to take netflow and output what the top traffic ASes to and from my AS are.   Something that we can look at every once in a while, and/or spin up and get data then shutdown..  Just have two ports need netflow from currently. 

 

Thanks in advance.
