I'm trying to monitor what devices are active in a Wifi network. This is specifically about mobile phones that connect to a Wifi-Router. While I do know how to enumerate Wifi networks in reach I would also like to enumerate devices that are connected to those networks. I do not have access to the routers, or to be precise, they run software that cannot be used to monitor them, but I do have a Notebook sitting next to the router.
Would something like airodump allow me to periodically enumerate the devices and write them to a file?
What OS is the notebook running? Kismet was written with this task in mind and is a standard package on most Linux distributions.
You could cron a script that redirects the output of
nmapto a file, and parse that file however you want.
