    Talking Im new. I need help. ioctl (SIOCSIFFLAGS) failed: No such file or directory

    Hi guys.. Im new with this Backtrack thing, I dont know anything bout programming or hacking etc. , but I just wanted to find the WEP of a wifi that Im detcting. I watched some YouTube videos and I kind of learned how to do it. I think its pretty easy. But my problem is that when I oppen the first Konsole in BT4, I type "airodump-ng wlan0" and i only get a message that says:

    ioctl (SIOCSIFFLAGS) failed: No such file or directory

    So Im not able to get the BSSID and the Chanel, I also tried "airodump-ng mon0" but I get the same answer.
    Well prety much thats all, I hope someone can help me. Thanks alot.

    What model of wifi access point is it that you are trying to crack?
    Capitalisation is important. It's the difference between "Helping your brother Jack off a horse" and "Helping your brother jack off a horse".

    The Forum Rules, Forum FAQ and the BackTrack Wiki... learn them, love them, live them.

    Read up on the program airmon-ng and your specific wireless card.

    Did you set your wireless card into monitor mode first? Then you can see which wireless you have to run with airodump-ng.
