My life and times.

This is my story and I'm sticking to it.

Netflow and IPv6

Now that I’m handing out IPv6 addresses to various VLANs on my network, I needed a way to see what percentage of my traffic was actually using IPv6. Enter pf, pflow, and ntop. pf is used by my router/firewall to process packets, and mark them for pflow processing. pflow is a psuedo device on the router/fw which exports pflow accounting data to a remote collector. ntop (and nprobe) is a collector and visualization application for digging into packet statistics.
