====== Aircrack-ng+Ubuntu+EeePC ======
I recently migrated my original 160GB drive to Ubuntu 10.10 Netbook Remix. I found it to work flawlessly on my 10" Asus netbook. I plan on using this as my pen-testing machine on the sandbox network I'm building at work. I figured I would get Aircrack-ng installed and running on the stock Wi-Fi card as an initial tool to try out. Plus, I have never actually got it working 100% and wanted to actually crack a wireless key. I didn't drive around the neighborhood looking for a WAP to crack. I just used my Droid with Barnacle to setup a network to break into.
Some preliminary installations:
sudo apt-get install gcc g++ build-essential libssl-dev libnl-dev
I also had to install the "negative one" patch. When I would try to run some of the aircrack tools, the channel would show up as -1.
wget http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2.6.tar.bz2 -O compat-wireless-2.6.tar.bz2
wget http://patches.aircrack-ng.org/channel-negative-one-maxim.patch -O channel-negative-one-maxim.patch
tar -xzvf compat-wireless-2.6.tar.bz2
cd compat-wireless-2.6.35-1/
sudo patch ./net/wireless/chan.c ~/Downloads/channel-negative-one-maxim.patch
sudo ./scripts/driver-select ath5k
sudo make
sudo make install
Reboot
Now download and install the Aircrack-ng suite.
Run airmon-ng once to look for any conflicting services or processes.
sudo airmon-ng
Stop services and kill processes it lists. I had to do the following:
sudo service network-manager stop
sudo service avahi-daemon stop
You may also have to kill the wpa_supplicant process.
Now you can go to the [[http://www.aircrack-ng.org/doku.php?id''simple_wep_crack|Simple WEP Crack Tutorial]] on the Aircrack-ng site.
When you're done capturing and want to utilize your Wi-Fi card normally, restart the two services stopped earlier.
sudo service avahi-daemon start
sudo service network-manager start
