Packet injection problems with madwifi-ng

[niux]

Hello !

I have some problems with getting the madwifi-ng to inject packets with my D-Link G650.
The thing is I'm doing a school project on wireless encryption and I need to demo how a WEP key is cracked (Yes the school admin as approved this). So I have bin trying on my home network for days now. I do a airodump on the right interface and on the right channel - it captures packets alright. I then start up aireplay to inject packets - when it catches its first ARP request it starts flooding the network with packets - only problems is tho that ariodump does not capture more IVs !? aireplay can send 64023 packets and airodump still only captured 23 IVs...

Before I do all this I create another interface and place it in monitor mode:
wlanconfig ath1 create wlanmode monitor wlandev wifi0

No problems here. I then makes sure that both interfaces operates on the correct channel:
iwconfig ath0 channel 6
iwconfig ath1 channel 6

The madwifi-ng drivers I installed is from the suse repository:
madwifi
madwifi-devel
madwifi-kmp-bigsmp
madwifi-kmp-default
all version 0.9.2

Some sites says the drivers needs to be patched to support injection and some others say that the newest drivers already have the patch - I assume I get the newest when i use the repository!? Anyhow I also tried to patch the drivers but was unable to. When I try to build the modules (make && make install) i get an error saying: Makefile.inc:91: *** KERNELCONF: /lib/modules/2.6.18.6-jen43-bigsmp/build/.config does not exist.. Stop.

I've bin googling this for days now and I cant seem to find anything on this problem, so I hope you can help me.

Thanks,
Niux

I just booted up with Backtrack 2 Beta and ran the attack again against my own network and it all went by the book. Which also means that my problem in Suse 10.2 most likely is the drivers missing the patch. Also concluding that either does the newest madwifi-ng not have the patch included or you do no get the newest version from yast.
