Hello Eliezer. Netflow will be the best solution to find the host that's generate load. First you need decide what netflow analyzer you'll use. I know about some plugin to Cacti. Than you need install IPT-NETFLOW to your Ubuntu router. Also you have another way, you can monitor (snmp traffic) all ports on switches and then find analyze. B.R. Murat

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 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1
