Monitoring mode for Alfa (RTL8187)

[johndoesenior]

For some reason the produced image doesn't have the drivers for the Alfa.

More over - it doesnt support monitoring mode at all (even for the built in wireless card).

Any suggestions?

Offensive security patches the kernel sources before building the arm-kernels:
echo "Patching kernel"
wget http://patches.aircrack-ng.org/mac80211.compat08082009.wl_frag+ack_v1.patch -O mac80211.patch
patch -p1 --no-backup-if-mismatch < mac80211.patch

I think, this patch is missing now, to get it work. But that's where the trouble begins:
Until now, I'm still not able to build my own kernel. That's the only reason I used the prebuild boot-image from the descriped ubuntu-Image from above. I tried the instructions at http://radxa.com/Rock/Booting_Linux (with and without kernel-patch, using the descriped cross-compiler as well as the following https://github.com/offensive-security/gcc-arm-linux-gnueabihf-4.7) without success yet.

You can find the scripts for building a kernel in my radxa workspace. The workflow would look like this:
./getKernelSource.sh (This would also apply the descripted kernel patch).
./createKernelConfig.sh (creates the .config file and allows you to modify it, if needed)
./createBootImage.sh (compiles the kernel and creates a Boot-Image)

But as mentioned before, the created BootImage didn't worked for me so far. So I left these scripts out of the build-process and just used an extracted, working boot-image from a ubuntu-Image -> but of course without the descripted patch.

Are you able to build a working boot-Image? Maybe, you see what I'm doing wrong creating a boot-Image. It would be a great improvement to use a self created boot-Image, since it would be possible to build the kali-Image from scratch and modifications like this patch could be applied.

Anyway, maybe it would also be possible to apply this patch on the builded image? I don't know...

I want for sure be able to build my own kernel, but the next weeks, I don't have much time to search the error here, so any help would be very welcome! :-)

RTL8187L is supported by airodump for Linux, but need patch.
RTL8188 is not supported.

I will try to patch it the next days... not much time left due to christmas

Hi everyone, thank you frep for your incredible work, And for continuing my first rock project. I have localy made some changes to my first script, I have embedded the kernel build commands for kali inside it. I will post my work as soon as possible. Keep up the good work.
