You're doing it wrong, you're supposed to use aireplay to fake the data packets, waiting for 20k packets can take hours, with aireplay you just need a couple of real packets and it will fake the rest. 20k packets -> 3min

@ThumbsUpCauseImRight Not really wrong, just using the most basic method. Aireplay generates traffic with various injection techniques like deauthentication and ARP injection. Packet injection involves more steps than I wanted in this basic tutorial. On a busy network, you can get 20k packets in 10-15 minutes. Injection works better for inactive networks. Maybe I should make an aireplay tutorial to go with this vid.

is aircrack already installed in backtrack? i dont have to install it to backtrack? and u do no if its include in with backtrack 4 also?

[crazypcdude]

The thing now that it is very slow to get data packests now I had Linux backtrack 3 run for like 10 hours and itstill did not came to 1000 data packes do you know why? I run linux backtrack 3 on Vmware workstation with 512 ram.

@Chakchi34 I could be that the computer you were trying to hack was not doing anything on the internet

[azneagledog]

one more thing, I got backtrack to run on my usb and aircrack works fine, but when I put backtrack in vmware player and virtualbox it wont work. It doesnt either say I have a wireless card and I'm doing this on my laptop. When I type airmon-ng, zero devices show up. Can u have?

it write me

@IrishPuglover3565 The more traffic on the network, the easier this will be. It doesn't necessarily have to be a person using it. Automatic updates and downloads will generate a lot of traffic at times. Once you get the handshake, you will be generating most of the traffic yourself.
