Hi guys, im here trying to find a replacement for my nfsen / nfdump
platform.
Im trying free version of ntop-ng , so here are some questions:

1) How to properly create a netflow analisis platform with ntop-ng?
I already installed ntop-ng + nprobe packages.
It seems to work ok but , but flows are limite to 25k.
Is there some free version for this ?

2) Is it possible to create custom traffic profiles from netflow data ?
For instance , I use to create some filters like:
src net x.x.x.x/24 and out if 13.
It seems to be a similar feature but it is only available at pro version.

3) How can I analize my traffic?
Is it possible to filter (as above) and sort by flow duration , traffic
rate, etc.
If so , please provide some howto, I can not get it.

Regards;
Leandro.
