Network traffic monitoring

Hello!

I'd like to do quite a simple thing: I have a (Suse) Linux file server
and internet gateway for my Home-LAN. I need to monitor the traffic to
the internet (separate for each computer in the LAN).

I tried ntop and it looks good, but it doesn't save the data
permanently. I activated the rrdplugin and it did create many files with
many data. But at first, it gathers more than I need, and it's quite
complicated to present the data in a graph or something.

My questions: Is there an easier way to achive what I want (using ntop
or some other tool)? Is there something like a script which can create
graphs automatically from all those rrd-files automatically?

Thanks, Nicolas

ipac-ng is an iptables+mrtg solution.

You define your rules (by ip/port/...) in a simple table and it add
iptables rules to your configuration ans send the output to mrtg to graph
the result.
