HostAP Ubuntu 7.04 Packet Injection

Ubuntu logo Feisty Fawn Do you have Z-Comax or other Prism based WiFi card (for example XI-626, XI-325)..? Ubuntu 7.04 Feisty Fawn, same as in the last version Dapper Drake can not do Packet Injection with hostAP driver. This is a short instruction how to change this situation. You need just to download 60MB source code, patch and install dpkg-dev and linux-kernel-devel. Start with creating the folder where the whole operation will run.

Make DIR and CD to directory

mkdir temp
cd temp

For outcome from compilation we create subfolder outemp and we copy into it the actual kernel config

mkdir outemp
cp /boot/config-2.6.20-16-386 outemp/
cp /usr/src/linux-headers-2.6.20-16-386/.config outemp/

Download linux image

apt-get source linux-image-2.6.20-16-386

Download packet injection patch

wget -nc http://rsappe.googlepages.com/hostap-kernel-injection-2.6.20-16.patch

Patch for older kernel 2.6.18 is at http://patches.aircrack-ng.org/hostap-kernel-2.6.18.patch

Run patch

patch -p1 < hostap-kernel-injection-2.6.20-16.patch

Modules compilation

cd linux-source-2.6.20-2.6.20/
make O=../outemp outputmakefile
make O=../outemp archprepare
make O=../outemp modules SUBDIRS=scripts
make O=../outemp modules SUBDIRS=drivers/net/wireless/hostap

Back up former modules and replace it for the new ones

cd /home/USER/temp/outemp/drivers/net/wireless/hostap/
sudo cp -dpR *.ko /lib/modules/2.6.20-16-386/kernel/drivers/net/wireless/hostap/

That’s all. Have fun.
