			In the process, I discovered a few things.

			===By The Way: Modifying Headless Raspberry Pi Boot Sequence===

			Part of my struggles in debugging the issue above led me to the <code>rc.d</code> and <code>init.d</code> on the SD card, and modifying the services that start on boot on the headless Raspberry Pi.

			Here's how to add and modify startup services and configurations on the Pi:

			First load up the SD card and mount it (as described at [[Kali_Raspberry_Pi/Installing#How_the_Kali_Linux_Startup_SD_Card_Works]]).

			Now you can modify files in the Linux partition, to change what starts up at different runtime levels. Debian Raspberry Pis start in runtime level 2, so anything you want to start up should go in <code>etc/rc2.d</code>.

			Actually, what you should do is, put a service script in <code>etc/init.d/myservice</code>, make it executable, then create a symbolic link in <code>etc/rc2.d</code>.

			More details here: http://raspberrywebserver.com/serveradmin/run-a-script-on-start-up.html

			===By The Way: Modifying Configuration Files on the Raspberry Pi===

			Note that the above handy trick, editing the Linux partition on the SD card, can also be used to modify configuration files for programs. Want SSH to listen on port 8080? You can edit the <code>etc/ssh/ssh_config</code> file to change the SSH configuration. Want to edit the crontab file? Go for it.

			YOU CAN DO... ANYTHING... YOU... WANT!!!

	==Setting a Static IP==		==Setting a Static IP==

	You'll want to set a static IP address for the Raspbery Pi before you boot. Assuming we're connecting the Pi directly to the laptop with a crossover cable, we'll use an IP address in the range <code>169.254.X.Y</code>. ~~This~~ is for networks ~~where~~ the IP ~~addresses are self-assigned~~. (~~I don't understand~~ this ~~exactly, but it works. More info~~ [https://pihw.wordpress.com/guides/direct-network-connection/in-a-nut-shell-direct-network-connection/ here]).		You'll want to set a static IP address for the Raspbery Pi before you boot. Assuming we're connecting the Pi directly to the laptop with a crossover cable, we'll use an IP address in the range <code>169.254.X.Y</code>. The IP prefix 169.254, like the IP prefixes 192.168 or 10.X, is a special IP address for special networks. In this case, 169.254 is the "link-local address" - an IP address range for devices connected directly to the computer with a crossover cable. (Original source of this IP address was [https://pihw.wordpress.com/guides/direct-network-connection/in-a-nut-shell-direct-network-connection/ here], but a search for 169.254 will point you toward the "link-local address" Wikipedia page [https://en.wikipedia.org/wiki/Link-local_address here]).

	My favorite IP address in this space happens to be <code>169.254.113.200</code>.		My favorite IP address in this space happens to be <code>169.254.113.200</code>.

Double Check your Pi Version

	==~~Double Check your Pi~~ Version==		==Download Correct Image Version==

	~~Although it's best to do this before you wait 30 minutes while your computer flashes an image to an SD card, you should probably check~~ to make sure your Kali Pi image matches your Raspberry Pi version. Version B+ has two USB ports, and Version 2 has four USB ports.		Check to make sure your Kali Pi image matches your Raspberry Pi version. Version B+ has two USB ports, and Version 2 has four USB ports. You can download your Raspberry Pi Kali image from the Offensive Security webpage: https://www.offensive-security.com/kali-linux-arm-images/

			There are 3 Raspberry Pi images listed on that page. I downloaded the "Raspberry Pi" image kali-2.0.1-rpi.img and this worked on the Raspberry Pi B (older design, 2 USB ports). If you have a B+ (newer design, 4 USB ports), get the "Raspberry Pi 2" image.

			Once you've downloaded the image. it will be named something like kali-2.0.1-rpi.img.xz. The xz extension means it is a compressed file, so decompress it with `tar xf kali-2.0.1-rpi.img.xf`.

			You can use the resulting image file to flash the SD card that your Raspberry Pi will use.
