ioctl(SIOCGIFINDEX) failed: No such device

[anarchoi]

Ok first off i have a Toshiba Satellite L300D with an Atheros AR700EG.

My laptop is not on the "supported hardware" list but i have read on google that all Atheros are supported... (could someone please confirm me that my hardware is supported?)

So i successfully managed to download and get Backtrack3 working on an usb key. I can boot it,

After aunching the console and typing "airmon-ng start wlan0" , here's what i get :

wifi0 Atheros madwifi-ng
ath0 Atheros madwifi-ng VAP (parent: wifi0)

(there is around 10 wlan around my house, and i don't see any, including the one i want to test with the proprietary's authorisation...)

then if i type "airodump-ng -w out -c 10 --bssid 00:16:41:C9:E0:3F wlan0" here's what i get :

Interface wlan0:
ioctl(SIOCGIFINDEX) failed: No such device

Any help would be greatly appreciated!

Hi anarchoi, actually there are threads that about atheros card just google "-=Xploitz=- VIDEO: Volume #1 "E-Z No Client WEP Cracking Tutorial""
but I am not yet allowed to post the link..

In backtrack3, the interface is not wlan0 but ath0...

Try:


bt ~ # iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wifi0 no wireless extensions.

ath0 IEEE 802.11g ESSID:"" Nickname:""
Mode:Managed Frequency:2.447 GHz Access Point: Not-Associated
Bit Rate:0 kb/s Tx-Power:18 dBm Sensitivity=1/1
Retryff RTS thrff Fragment thrff

Link Quality=0/70 Signal level=-96 dBm Noise level=-96 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0

bt ~ # airmon-ng start wifi0


Interface Chipset Driver

wifi0 Atheros madwifi-ng
ath0 Atheros madwifi-ng VAP (parent: wifi0)
ath1 Atheros madwifi-ng VAP (parent: wifi0) (monitor mode enabled)

Then you can work with ath1:

bt ~ # airodump-ng ath1

Another method you can try:

bt ~ # iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wifi0 no wireless extensions.

ath0 IEEE 802.11g ESSID:"" Nickname:""
Mode:Managed Frequency:2.447 GHz Access Point: Not-Associated
Bit Rate:0 kb/s Tx-Power:18 dBm Sensitivity=1/1
Retryff RTS thrff Fragment thrff

Power Managementff
Link Quality=0/70 Signal level=-96 dBm Noise level=-96 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

To destroy ath0 completely:

bt ~ # wlanconfig ath0 destroy
bt ~ # iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wifi0 no wireless extensions.

To create ath0 in monitor mode:

bt ~ # wlanconfig ath0 create wlandev wifi0 wlanmode monitor
ath0

Then you can work with ath0:

bt ~ # airodump-ng ath0

Hope this helps.
