Raspberry Pi TODO

A collection of resources, links, and todo items as I tinker with the amazing little Raspberry Pi.

Reference

Raspberry Pi: BitTorrent Sync

This Gist will install and configure BitTorrent Sync on a Raspberry Pi running Raspbian. By default, BT Sync will be bound to the address 127.0.0.1. Meaning the web interface is not accessible from any machine besides the Pi. This script will enable access from any machine on the network.

Installation

To perform the default installation of BT Sync, simply execute the following after SSHing onto the Pi.

curl -s -L http://go.trav.sh/pi_btsync | bash
