Script to automatically provide internet access to a PiZero connected to a Linux host over a USB-network (only tested on Ubuntu 14.04)
#!/bin/bash
# Automatically setup routing and DNS for a PiZero connected over a USB-network
# NOTE: Before running this script for the first time, you need to run the
# following two commands on your Linux PC
# sudo sysctl -w net.ipv4.ip_forward=1
# sudo iptables -t nat -A POSTROUTING -s 169.254.0.0/16 -o eth0 -j MASQUERADE
# (replace eth0 in the second command with your internet-facing network device,
# e.g. wlan0 on a laptop)
# The Avahi-discovered hostname

Simple guide for setting up OTG modes on the Raspberry Pi Zero

Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int
