OLAGuruPlug

This describes how to setup OLA on a GuruPlug. These devices make excellent low cost DMX512 nodes.

Prerequisites

This assumes you have a shell on the guru plug and that it can contact the internet to download the packages. Note that the default guru plug is insecure and comes with a lot of extras (samba, myqls, lighthttpd etc.) that aren't required. Fixing this is outside the scope of this tutorial.

Setup

Add a user ola for the daemon to run as:

 $ adduser ola 

If you intend to use USB devices, you need to add this user to the plugdev & dialout groups. Modify the lines in /etc/group:

 dialout:x:20:ola
 plugdev:x:46:ola

Finally add any udev rules that you'll need. See OLA Device Specific Configuration

Running

Change to the ola user and the start the daemon:

 $ su ola
 $ olad -l 3
