===== Injection Walkthrough =====

This is for an intel PRO/Wireless 3945ABG WLAN (802.11a/b/g) card.

I've tested this on [[http://www.ubuntu.com/getubuntu/download|Ubuntu]] 7.10 Gutsy Gibbon - x86 architecture - 32 Bit, but I don't see why it shouldn't work on other OS's. Some commands might be different however, especially the ones involving apt-get.

You need a Internet Connection with your LAN Cabel.

Open a Terminal and type...

**Pre requirements**
<code>
sudo apt-get install build-essential
sudo apt-get install libssl-dev
</code>

// For openSUSE and other RPM-based distros, this is different (replace "zypper" with your distro's package manager): //
<code>
sudo zypper install gcc
sudo zypper install libopenssl-devel
</code>


**Installation**

  * Download ipwraw-ng from http://homepages.tu-darmstadt.de/~p_larbig/wlan/ or http://dl.aircrack-ng.org/drivers/ (2.3.4 is the latest as of 11 February 2008)

  * Install the modules and ucode

  * Blacklist ipwraw (so it's not automatically loaded at boot time)

<code>
wget http://dl.aircrack-ng.org/drivers/ipwraw-ng-2.3.4-04022008.tar.bz2
tar -xjf ipwraw-ng*
cd ipwraw-ng
make
sudo make install
sudo make install_ucode
echo "blacklist ipwraw" | sudo tee /etc/modprobe.d/ipwraw
sudo depmod -ae
</code>

**Use ipwraw-ng**

  * Unload the ipw3945 module
  * Load ipwraw-ng

The device created will automatically be in monitor mode. 

<code>
sudo modprobe -r ipw3945
sudo modprobe ipwraw
</code>

The new device name for injection should should be called wifi0 and the monitor interface should be rtap0.  iwconfig can be used to display the current wireless interfaces.

<code>ubuntu@ubuntu:~$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

wifi0     unassociated  ESSID:off/any 
          Mode:Monitor  Channel=11  Bit Rate=1 Mb/s

rtap0     no wireless extensions.</code>


IMPORTANT before using airodump-ng you need to :
# ifconfig wifi0 up

**Configure your Wireless Card**

You can use iwconfig to set the channel and rate and transfer power. 

<code>
iwconfig eth1 channel 11 (on which you want to sniff)
iwconfig eth1 rate 1M (min=1M and max=54M)
iwconfig eth1 txpower 16 (min=-12 and max=16)
</code>

And when you're done,

<code>
sudo modprobe -r ipwraw
sudo modprobe ipw3945
</code>
