can u give more info?
I just got an eeepc 4G, and i have no experience on the madwifi driver, i cannot set it to master/ap mode. How did u do it?
Also u may have to edit a couple of files into the karma directory. I had to edit modules/servers/AccessPoint/module.xml cause it was pointing iwcommands into the /usr/sbin folder when in BT3 final, they are in /sbin/
and u may have to edit a couple of other files two (maybe comment out some useless features in some modules, eg. take out the "change mac address function" cause we are doing pen-testing so we dont wanna hide our mac right?..)
edit: never mind, i found out how to set ath0 into master mode.
but still i dont get the karma option from the iwpriv...
anyway, i suggest u to try this new approach from H.D.Moore since it uses aircrack-ng tools to work, and doesn't mess with drivers etc. it only requires injection support:
