How to detect Sonos devices on your network

A potential project requires me to detect Sonos devices on a network and find their IP addresses. Since Sonos only has 2 Mac Address OUIs an ARP scanner seemed the best way to do this. As such, I rightfully reinvented the wheel and wrote a slightly glorified ARP scanner with detection for Sonos OUIs. Sadly, PHP wasn’t quite suitable for this due to it’s lack of AF_PACKET sockets so it’s in C.

It’ll run on Linux and scan a network when given an interface name. Tweaks more than welcome as GitHub Pull Requests.

Code’s on my GitHub at https://github.com/phil-lavin/sonos-detector.
