Imagine this situation that there are some smartphones and computer around with their WiFi adapter (wireless adapters) on, but not necessary connected to a network.

Is there a way to look the MAC addresses via a Linux machine?

Any insights are appreciated.

You can use a tool such as kismet,, to scan for wireless networks. I believe it can show you all wireless devices in your vicinity without having to have the devices being actively connected to same network.

This post should give you a rough idea of how to accomplish the scanning of the network using Kismet.

Also as a side note you can use this tool, fing,, to find out all the MAC addresses of the devices on your network.

% sudo fing
