Hi,

I'm pretty sure there isn't a quick way. You'd have to have a wireless interface that supports 802.11 monitor mode, which not all AirPort cards do, and you'd need to snoop for the probe responses from the AP you're associated with (you'd need to initiate the probes somehow), and you'd have to parse the raw 802.11 packets yourself. None of the functions for doing that in the AirPort drivers are visible in the network interface API.

Yeah, I'm familiar with the external methods (passive mode grabbing probe frames, etc.). For that I could use KisMac and Wireshark. I just wasn't sure if there was anything even remotely close in the API. I'm asking because a member of the University for which I work was hoping to create an A-based network; forcing client cards to use 802.11a and having some sort of tool to verify. I was going to whip up something quick for him. Oh well.


Not publicly available.

I don't want to pry, and if the question is not appropriate, it's OK to disregard: Is the lack of these two functions due to security concerns or Apple dev manpower?
