Slackware Notes

Here you'll find an overview of some guides and various technical notes I've written while playing with various operating systems.

Enable orinoco monitor mode on Slackware 10.2 (i.e. patch the orinoco drivers)
October 11th, 2005 - 08:39 am

Download the Orinoco version 13e driver: http://prdownloads.sourceforge.net/orinoco/. Local mirror here.
$ wget http://www.cilinder.be/orinoco/orinoco-0.13e.tar.gz
Download the monitor mode patch (orinoco-0.13e-patch.diff): http://airsnort.shmoo.com/orinocoinfo.html. Local mirror here. This patch enables an Orinoco wireless network card to be placed into monitor mode sending raw packets to the user via the PF_PACKET interface.
$ wget http://www.cilinder.be/orinoco/orinoco-0.13e-patch.diff
Download the dragorn performance patch (orinoco-0.13e-dragorn3.diff): http://www.kismetwireless.net/download.shtml#orinoco. This patch addresses problems related to slow channel changing performance while scanning in monitor mode. Channel changing performance is improved with this patch. Again, I've locally mirrored this patch here.
$ wget http://www.cilinder.be/orinoco/orinoco-0.13e-dragorn3.diff
Unpack the orinoco driver:
$ tar zxpvf orinoco-0.13e.tar.gz
Change to the newly created directory:
$ cd orinoco-0.13e

Apply the rfmon patch:

$ patch -p1 < ../orinoco-0.13e-patch.diff

Apply the dragorn patch:

$ patch -p1 < ../orinoco-0.13e-dragorn3.diff

Compile the driver:
$ make
Become root:
$ su
Install the driver:
# make install
Unplug your wireless card and re-insert it. You should be able to issue the monitor command now...
