Raspi 3

A project log for Raspberry Pi MAC/IP Monitor

A Raspberry Pi network monitor, specifically an appliance that watches for new MACs, and IP addresses.

I picked up a couple of Raspberry Pi 3's at MicroCenter this weekend. I had some issues getting them started (I switched one of my installs with the new board). It turns out that they're going to be finicky about power supplies (duh). My previous Raspi 2 was running on a .7 amp power supply. The 3 did not like that and booted erratically.

However, I eventually figured it out, and got things running and configured (anyone know a great way to apply the same configuration to multiple Pi's, quickly?). I cloned the project repo to the Pi, and ran it. Typically, the Raspi 2's have been scanning the network over 25 seconds or so (scanning just the final octet, or /24 CIDR, or the last 255 addresses). That's a LOT slower than I wanted. Switching over to the 3, and it is scanning the same network space in just over a second. That is going to work. However, I'm getting different results from the two systems, and I can't explain that.

So... more work to be done! I'll keep this page updated with progress on this portion of the home sensor network project: https://hackaday.io/project/9754-raspberry-pi-sensor-network
