In fact, Aircrack-ng is a set of tools for auditing wireless networks.
Step 1 :
sudo apt-get install build-essential sqlite3 subversion ethtool
svn co http://trac.aircrack-ng.org/svn/trunk aircrack-ng
make sqlite=true ext_scripts=true unstable=true
make sqlite=true ext_scripts=true unstable=true install
Step 2 :
To run it with ALFA AWUS036NH (802.11 b/g Long-Range USB Adapter), you can run the command at any directory.
airmon-ng start wlan1
airodump-ng mon0 -c 1
To test it if is is injectable or not.
aireplay-ng -9 mon0
Step 3 (Optional) :
For Intel Corporation PRO/Wireless 5100 AGN [Shiloh], you need the following commands :
airmon-ng start wlan3
airodump-ng wlan3mon -c 1
At this writing, I cannot find a way to solve the problem in airmon-ng or airmon-zc for ALFA AWUS036NHR. However, Pentoo 2013.0 RC1.1 is working perfectly for that adapter.
That's all! See you.
