Implementation Details

Server

The Raspberry PI is running an apache2 server. The main config file is located at /etc/apache2/apache2.conf. The Sinatra roomba server runs on port 4567 be default. We wanted to enable access to the server through port 80, simply by typing roomba.local in the browser address bar. In order to do that, we added a reverse proxy configuration to apache:

1. Installed a revesre proxy module via a2enmod proxy_http (see this link).
2. We created /etc/apache2/sites-available/roomba.
3. We created a symlink to that file: /etc/apache2/sites-enabled/roomba.
4. We removed all other symlinks from /etc/apache2/sites-enabled/, so that they don't collide with our reverse proxy configuration.
5. Then we restarted apache by calling sudo /etc/init.d/apache2 restart.
