Detecting the presence of wifi devices

  • Is it possible, with a normal wifi adapter, to detect present wifi devices in the surrounding? Let's say, is it possible to detect an Iphone with wifi switched on in the range of my wifi adapter?

    Perhaps it's possible to create a fake AP with an ESSID and encryption thats stored in the favorites list of the device that should be detected, but actually I am searching for a more generic way, without knowing the favorite networks.

    Also, I remember I had found special hardware once for this purpose, but again, I am looking for a method where standard hardware can be utilized.

    You will need a wireless nic that permits a 'monitor' mode, and that requires some special drivers and special nics.

    • Kismet's list of cards for Linux
    • tests on different cards
    • pineapple device (special device)
    • airpcap nic (specialized nic for Windows)

    Once you get a card, you will need software to deal with the data and Kismet is the leader in this area right now.

    +1 Backtrack makes a very easy environment for wireless site surveys - Kismet and associated packages let you also map wireless devices along with google map plugins - very useful for larger sites.

    I've got a few alfa usb adapters in the lab. there are the recommended ones for aircrack, I think they might work, I will give it a try. thanks!
