Aircrack

Install aircrack-ng

For compiling injection drivers.

install kernel-headers

Optionally install kismet.

install injection enabled network drivers. I use a netgear 122 with a ra73 driver.

Remove maybe conflicting driver.

mv /lib/modules/`uname -r`/kernel/drivers/net/wireless/rt2x00/* /tmp/rt2x00
depmod -ae

Build drivers.

wget http://homepages.tu-darmstadt.de/~p_larbig/wlan/rt73-k2wrlz-2.0.1.tar.bz2
tar -xjf rt73-k2wrlz-2.0.1.tar.bz2
cd rt73-k2wrlz-2.0.1/Module
make
make install
modprobe rt73

Load and tweak driver.

ifconfig rausb0 up
iwconfig rausb0 mode monitor
iwpriv rausb0 rfmontx 1
iwconfig rausb0 rate 1M
iwconfig rausb0 mode monitor
