I see a list on the KisMAC website of a bunch of adapters that are
known to work. What's required to make them work with KisMAC? Does
there need to be a driver so that OS X can use the adapter as a
network connection, or does KisMAC talk to the USB adapter directly?
And would I need to load any KisMAC drivers to talk to a USB adapter?
KisMAC does two types of scanning; active, and passive.
Active works much like Netstumbler under Windows, and for the same
reasons - it basically sends out packets on every channel, and
'detects' AP's by getting a response back from one. Advantages: As
long as you have a wireless card with drivers, and KisMAC has basic
support for it (channel swapping, etc), it'll probably work.
Disadvantage: It's very possible to tell there's somebody wardriving,
and you're only going to see AP's that will talk back to you.
Passive mode talks directly to the card - it sticks it into a certain
mode, and *listens* for any traffic on the channels its scanning.
Advantage: Absolutely nothing is sent out, so nobody knows you're
scanning, and you'll pick up a hell of a lot more - tunnels, adhoc
peers, AP's with SSID hiding. Disadvantage: KisMAC needs to understand
very specifically the chipset of the card itself, regardless of drivers
(you don't even *need* drivers installed for KisMAC to talk to a
Your best bet is something Prism based. The 200mW cards are especially
(Does KisMAC support /any/ USB adapters in passive mode, regardless of
chipset? If so, I'm impressed.)
Signature space for rent.
