SiLK is a powerful toolset for analyzing netflow and pcap data
generated from TCPDUMP. It's a slight learning curve, but worth it
IMHO. Fairly good documentation too.
From that toolset, you can use "rwptoflow" to generate flow records
from TCPDUMP to SiLK format.
You might also look at "softflowd"  or similar tool to export
netflow records from whatever box your using TCPDUMP to capture
data. Then you can output netflow records directly to most of the
aforementioned netflow packages. Having the actual packet data is
useful later once you've found something suspicious, or for snort.. etc.
