Kismet and Leopard
dr
So, Apple changed some things around when they did Leopard, and broke the recently-added
Kismet support.  BUT, it's fixed now in SVN, and as soon as some Maemo stuff is done I'll
package it into a release.  For those who want to get into it now, a *very* current libpcap
is a must.  From CVS current.  This is because it seems Leopard subtly changes how it does
DLT enumeration, which means existing libpcap releases won't find the 802.11 DLT and won't
be able to figure out how to flip it into rfmon mode.

With Leopard, the wltN device has gone away, give Kismet the enX device.  The device 
initialization code on the darwin source will figure out your kernel version and try to
Do The Right Thing.
