I have been playing outside of the maemo repositories and decided to give everyones favourite ’security’ program Aircrack (aircrack-ng) a go. After setting up a debian repository from an official mirror installation was easy via the command line, a simple sudo apt-get install aircrack-ng.

Once installed, you cannot use the program straight away. This is because your wireless card will already be in use, or have been set up for ‘Managed mode’ where the operating system deals with setting up wireless networks. To get out of this, and into Monitor mode, you will need root access and go through the following commands:

root

ifconfig wlan0 down

iwconfig wlan0 mode Monitor

ifconfig wlan0 up

If you wish to use a different mac (useful when doing a fake auth,) go through the same process but instead of setting monitor mode use macchanger (e.g. macchanger mac=11:22:33:44:55:66). You can now use monitor mode and aircrack in all it’s glory! See the following for an injection test:

I crashed out early, due to my battery being on its last legs!

This is the result of a dump, the command used here was airodump-ng wlan0 -c 6

As you can see the N900 captured my WPA handshake, so I could crack my own WPA network; but that would be silly!

Airodump running on the N900: hope you like my faked mac address!

So aircrack looks like it can simply be moved to Maemo-extras (devel or testing.) It just needs more testing to check if inject is really working. My N900 had been up for 48 hours at this point, so didn’t wish to comply with testing
