I would like to have a fingbox-like home netwok monitor. I have a raspberry pi that I could run 24/7 (linux - ARMv8 architecture), and I also need a web interface. The solution has to be free (or open source). I'd like to detect if a new device connects to a network and get a notification (in any form, e-mail is fine). It'd be great if I would have access to the connection information concerning the devices connected to the network. I don't know if it's possible, but blocking devices from accessing the internet (you can do this on a real FingBox) would be an awesome feature to have. Is there a program that I could use to achieve the things I mentioned above? (I've found Nagios, but it doesn't run on the raspberry pi).
