Seeing and Hearing Internet Background Radiation

Is there more Internet Background Radiation than what you see here? Absolutely. This page shows the chatter reaching our servers through 8 common protocols, but the internet is much noisier than that. Knock-knock is open source and extensible; we have already used it to listen for more specialized protocols beyond this public view. To explore the code or build your own listener, visit github.com/djkurlander/knock-knock.
