Port Forwarding in Mavericks

Since Mavericks stopped using the deprecated ipfw (as of Mountain Lion), we'll be using pf to allow port forwarding.

####1. anchor file Create an anchor file under /etc/pf.anchors/<anchor file> with your redirection rule like:

Raspberry Pi and the USB to TTL Serial Cable on Mac (unfinished)

I took it to heart when @kassandra_perch said to document everything durring her talk at EmpireJS. So I documented my whole process, what went right and what went wrong.

This document is unfinished and is not a complete tutorial

The primary way to interact with a Raspberry Pi is to use WiFi and SSH. The problem with this is that the WiFi on the Pi needs to be configured and in order to do that you'll need a monitor. I've tried to edit the wpa_supplicant.conf by using the SD card's file system. I achieved this with minimal success the problem with this is that you still need to get the IP address of the Pi, even if it's connected.

Alas, there's another way! Using a wire referred to as the "USB to TTL Serial Cable - Debug / Console Cable for Raspberry Pi".

The "intellibook" netbook contains a rtl8192se pci network chip that is not currently included in the android-x86 builds. I could not get a complete self-build image to work so I decided to add the neccessary drivers to the existing release from 20120101. This has the added benefit that the installation contains the google apps, which are not included in the source download. The image can be downloaded from http://www.android-x86.org/releases/build-20120101 (android-x86-4.0-asus_laptop-20120101.iso).

Extract the iso image and the contained squashfs image and mount the contained filesystem image as a loopback device.

$ bsdtar -C android-image -xf android-x86-4.0-asus_laptop-20120101.iso
$ cd android-image
$ unsquashfs system.sfs
$ sudo mkdir /mnt/iso
$ sudo mount ./squashfs-root/system.img /mnt/iso  -o loop
