Hello,
I'm working on a Mac OS X 10.5 application that captures packets from
the Apple Airport Extreme card in my MacBook. I was able to get it
into rfmon mode thanks to Kismac's source code but when trying to
capture packets with libpcap going between my iPod Touch and MacBook I
only get the packets going from the AP to the iPod Touch and not going
from the iPod Touch to the AP. I'm using a slightly modified version
of the example code from Tim Carsten's pcap tutorial on tcpdump.org, http://www.tcpdump.org/sniffex.c
with the only modification being the code to get the card into rfmon
mode.
I'm using an unencrypted wireless network for testing. Does anyone
know why it would only catch packets coming from the AP and not going
to the AP? If you want to see the actual code I'm using let me know
and I'll send it to you.
Thanks,
Chris Benedict
