How to Bake an Onion Pi

I’ve always been kinda lazy or convenient I see no use of re-inventing the wheel again and found a great guide in how to make an onion pi from  http://makezine.com/projects/make-36-boards/how-to-bake-an-onion-pi/

Once downloaded the script file an unpacked and ran it.

There it should work but i was using a ralink 5370 usb wifi dongle so no joy at all since the guide was based on another brand.

I actually had to open pifi.sh script and a make a few modifications.

But the script that is working is pasted here.

#!/bin/bash
# Based on Adafruit Learning Technologies Onion Pi project
# More info: http://learn.adafruit.com/onion-pi

if (( $EUID != 0 )); then
echo ”This must be run as root. Try ‘sudo bash $0′.”
exit 1

After reboot service isc-dhcp-server will probably have error message to have that fixed enter

sudo nano /etc/default/ifplugd

and change INTERFACES=”auto”
HOTPLUG_INTERFACES=”all”

to

INTERFACES=”eth0″
HOTPLUG_INTERFACES=”eth0″

exit with ctrl-x and choose save.

This guide is based on

http://sirlagz.net/2013/02/10/how-to-use-the-raspberry-pi-as-a-wireless-access-pointrouter-part-3b/

Reboot and you should be good to go.

Good Luck !!
