Setting up a Raspberry Pi B

Here's how to set the hostname: http://xmodulo.com/how-to-change-hostname-on-linux.html

Prerequisites

My pi didn't have git and was out of date:

sudo apt-get update
sudo apt-get install git

Need the media player:

sudo apt-get mplayer

Now get the doorbell projects:

mkdir projects
cd projects
git clone https://github.com/bradxn/doorbell.git

Install rmate on the pi:

sudo wget -O /usr/local/bin/rmate https://raw.github.com/aurora/rmate/master/rmate
sudo chmod +x /usr/local/bin/rmate

To make changes from the Mac:

Install an editor or editor extension that supports rmate.

Start the rmate tunnel on the Mac in a terminal:

ssh -R 52698:127.0.0.1:52698 [email protected]

(Change the IP address to match the pi). In VSCode: Press F1 and type Remote: Start server, and press ENTER

Now, on the pi, run:

[sudo] rmate <file-to-edit>
