Hello every one Smiley
 
It is my first tuto so be gentle Cheesy
Ok folks i see that this post is quite popular so i will make a little tutorial to guide you to achieve injection whit an intel centrino A/G/B (ipw3945)
 
First you all need to know that i am a newbie on linux so most of the time i won't be able to sort problems if they occurred!
The second thing is that this driver is under development so if you are lucky it will work and if not, the people from intellinuxwireless.org will be happy to receive bug reports.
 
Packages required :  
 
kernel 2.6.20.1 and above.
kernel source (according to the kernel version)
kernel compiler (any of your choice)
GIT package (http://www.kernel.org/pub/software/scm/git/)
Wget package
 
 
a) Install the right kernel, information can be found at  (http://www.digitalhermit.com/linux/Kernel-Build-HOWTO.html) on how to install and configure your kernel.
b) Install GIT software, read the readme file in the .tgz file for a how to install.
 
!!!!! IMPORTANT make sure to have a kernel backup if things go wrong !!!!!!!
!!!!! If you are not sure what you are doing don't follow this tutorial !!!!!!!
 
First you will need the Latest iwlwifi uCode :
 
now make :
% wget http://intellinuxwireless.org/iwlw [...] 2.14.1.tgz
% tar xzvf iwlwifi-ucode-2.14.1.tgz
# cp ipwlwifi-ucode-2.14.1/iwlwifi-3945.ucode /lib/firmware
 
To download the rest of the drivers  in your home directory make :
 
% mkdir wifi
% cd wifi
% git clone http://intellinuxwireless.org/repos/ipwraw.git
% git clone http://intellinuxwireless.org/repos/mac80211.git
 
If all went ok two new folder should appeared now.
 
Do now :
 
% cd mac80211
% make patch_kernel
% cd /lib/modules/$(uname -r)/build
% make menuconfig
 
in the menu go to “networking”
there will be an entry “Generic IEEE 802.11 Networking Stack (dscape) (NEW)”
select it and press the “M” key.
exit and save.
 
now make :
 
# make modules modules_install
# make all install
 
Now you will need to reboot! so bookmark this page and see u in 2 min.
 
Now go back to your home directory and make :
 
% cd wifi/ipwraw
% make all
# make install
# cp util/wifi_tx /bin
 
now you just can load the module by :
 
# ./load [target channel]
 
If there was no problem until here that is it ! The injection interface name should be called wifi0
and the monitor interface should be rtap0
 
IMPORTANT before using airodump-ng you need to :
# ifconfig wifi0 up
 
This is not a stable version so some attack of airodump-ng will not work!
you will need to use “wifi_tx” see later posts.
 
have fun with centrino injection Cheesy

now make :
 
# make modules modules_install
# make all install

Pourquoi faire un lien symbolique de /lib/modules/... vers /usr/src/... ??
Tu ne peux pas patcher directement dans /usr/src ?
