I found my problem. Two issues:

1. I didn't have CEF enabled on the router (not mentioned in the CICSO
docs!)

2. netstat showed high RECV-Q stats for 2055 on my Linux box. Restarting
NTOP resolved this.

My NetFlows still does not show any packets or traffic? I don't know if this
is important since I am getting data from netflow.

I have to give credit to a doc I found on google. Read it at:

Actually IIRC the module doesn't give the kind of stats you were looking
for. I
mean even if it recieves che netflow datagrams and calculates the stats,
that
counters are incremented. They actually don't work. Just switch to the
netflow-device and look at the ntop host or traffic stats, and see if
everything
is fine. I don't know if the NTOP team reccomends a particular distro, but i
wouldn't say there's one.
