Airodump-ng with iwn0

eyebone · Oct 23, 2011

hello folks,

i am using a

Code:

iwn0: <Intel(R) Centrino(R) Ultimate-N 6300> mem 0xf2500000-0xf2501fff irq 17 at device 0.0 on pci3

in a x220.

i just tried to use airocrack-ng suite without any success.

Code:

airodump-ng wlan0

 BSSID              STATION            PWR   Rate    Lost  Packets  Probes

airodump-ng is not able to find any stations, never the less i know there are like 20 different networks(i could even proof it with a windows 7 machine next to me

).
so i tried to enable monitor mode on both devices iwn0 and wlan0 with:

Code:

ifconfig iwn0 monitor
ifconfig wlan0 monitor

same result in airodump-ng as before.
can anybody tell me if this piece of software is working together with iwn on fbsd or what to change/enable else?

if this is not possible, any other software to propose?

thanks and best regards,
eyebone

How are you enabling monitor mode?
# ifconfig wlan create wlandev iwn0 wlanmode monitor

Many thanks for your reply. I get the following output on a FreeBSD 9-RC1:

Code:

# ifconfig wlan1 create wlandev iwn0 wlanmode monitor
ifconfig: SIOCIFCREATE2: Input/output error

Is the card not capable of the function? Wrong commandline command?

Destroy wlan0 first.

iwn driver supports only one wlan interface at time.

Errrm, I think that you should use
# airmon-ng stop iwn0
# airmon-ng start iwn0
airmon will automatically create an interface mon0 (iwconfig should show 2 interfaces now) and you can run all commands through mon0. This also is the needed structure when you have 2 terminals open, 1 monitoring and the other injecting through iwn0. To stop mon0:
# airmon-ng stop mon0
I believe this is the preferred way to use the tool.
