Karma and madWifi

[thomaspu]

I've been searching the net form some more info on my problems and I'm wondering if anyone here has encountered and figured it out.

First, I was trying to get the Karma scan part running. I got the card in monitor mode but it craps out with some init_pcap error:

bt ~ # ifconfig ath0 down
bt ~ # wlanconfig ath0 destroy
bt ~ # wlanconfig ath create wlandev wifi0 wlanmode monitor
ath0
bt ~ # iwconfig ath0
ath0      IEEE 802.11g  ESSID:""  Nickname:""

          Tx excessive retries:0  Invalid misc:0   Missed beacon:0
...omitted the rest

bt karma # ./bin/monitor-mode.sh ath0
+ INTERFACE=ath0
++ which iwconfig
+ IWCONFIG=/usr/sbin/iwconfig
++ which ifconfig
+ IFCONFIG=/sbin/ifconfig
+ '[' 1 -lt 1 ']'
+ '[' linux-gnu = FreeBSD ']'
+ /sbin/ifconfig ath0 down
+ /usr/sbin/iwconfig ath0 channel 1 mode monitor essid any
+ /sbin/ifconfig ath0 up

bt karma # ./src/karma ath0
init_pcap: no suitable datalink decoder found

Any pointers as to what I'm doing wrong with that part would be helpful. I've had it running once before... I just can't get it going now.

Then theres the 2nd part I'm having issues on. I'm running: bin/karma etc/karma.xml and the error that I'm seeing is this:
SIOCSIFHWADDR: Invalid argument
Error for wireless request "Set Mode" (8B06)
SET failed on device ath0: Invalid argument
normal or supposed to happen?

bt karma # ./bin/karma etc/karma.xml

From what I've found elsewhere, I've seen one or two people who were able to get their setup working and didn't have that error. My wireless network card is a Netgear WG511T.

Anyone have any ideas/suggestions?

Thanks,
Paul

Ok, I've managed to make some progress. This error:

SIOCSIFHWADDR: Invalid argument

means that one of the scripts attempted to change the MAC address of our network card. Commenting out that part in the scripts got rid of that problem. The code they ran was:

ifconfig ath0 hw ether xx:xx:xx:xx:xx:xx

which the madwifi driver doesn't allow. I could probably keep the functionality if I changed the MAC address according to how the madwifi user guide says to.

The next error I had was in ./modules/servers/AccessPoint/accesspoint.rb:

Error for wireless request "Set Mode" (8B06)
SET failed on device ath0: Invalid argument

Was that the script(s) were trying to run:

ifconfig ath0 mode manage

also do not work on the madwifi driver in BT3. The correct way to do it is to run:

wlanconfig ath0 destroy
   wlanconfig ath0 create wlandev wifi0 wlanmode master

But Now I have a new problem that I'm stuck on. I'm trying to run

bt karma # ./bin/karma ./etc/karma.xml

Anyone? Help!
