net_glance: Investigate into the use of scapy

[henryj320]

Figure out how to use scapy.

To prove you know it, output all devices on the network (in any format).

Completed the investigation. Seems useful.

Only limit of Scapy is that it cannot get the hostname. socket.gethostbyaddr() is an option, but seems to fail on anything that is not localhost.

My solution is a JSON file containing key : value pairs of MAC-address : hostname which can be accessed. It will work for all of my devices, but will have to say "Unknown device" for anything not usually on the network.

{
     MAC-address: [ hostname , alias ]
     "C0:33:5E:2E:CC:0B": ["ubuntu-surface-3", "henry-ubuntu-surface-3"]
}

The format for aliases should be: person-os-model

On Ubuntu, you can use hostname to get the hostname or just look in the setings for hostname and MAC address.
