Hey all,

I have a tiny linux router based on ubuntu and sometimes I get a
massive load of UDP traffic because of one of the PCs in the network.
Usually I handle the situation with a strict block using iptables.
The main issue is to find it due to the load.
For now I am monitoring the traffic load using MRTG but it won't
notify me.
I can try to use nagios to monitor traffic load for a period of time
but before I start working on it I want another person opinion and
options.

I have seen netflow in the past but never actually used it.

Thanks in advance,
Eliezer
