If I see a Wifi network, how can check what's the type of the Wifi host - a router, a computer, a smartphone, a tablet? Is there something like a fingerprint, similar to User-Agent headers in browsers? Probably I can do that with BackTrack / Kali Linux, but I don't know which of the included tools to use. I am open to suggestions for any other tools.
What's a "WiFi Host" ? That's not common terminology. WiFi topology comes in two main flavors, ad-hoc and using access points. – MSalters – 2014-03-05T15:18:54.717
Sorry for the wrong terminology. I mean the device, to which I would connect if I join the WiFi network. – Alex Popov – 2014-03-05T15:20:28.703
