I found a very inspirational story: http://en.wikipedia.org/wiki/Discovery_of_cosmic_microwave_background_radiation Unless more flaws show up in the idea[1] a start at "cbbd" will be coming soon to a git repo near you. -- Dave Taht http://nex-6.taht.net 1: one flaw already - ntp rawstats output is inadequate. Parsing tshark -f "src or dst port 123" output would allow us to distinguish between natted and non-natted sources.
