Getting Kismet to work with Intel wifi Centrino 2230 on Ubuntu 12.10

I had some trouble setting up my laptop with kismet, so I just leave this here for anyone interested doing the same with similar wifi device.
Tried lsmod and modinfo, but nothing worked. Finally stumbled upon a couple of forum posts that led me to the solution.

su
apt-get install kismet
vi /etc/kismet/kismet.conf

#edit sources to this.
source=iwl4965,wlan0,iwlagn

#now running kismet will get you the following error:
---
Launching kismet_server: //usr/bin/kismet_server
Suid priv-dropping disabled. This may not be secure.
No specific sources given to be enabled, all will be enabled.

#This will fix that for ya.

ifconfig wlan0 down
iwconfig wlan0 mode monitor

kismet


that's all.
