Open Lighting Architecture
Link:  Linux Compatible Sends DMX Receives DMX Free
LLA Live is a stand-along bootable cd containing software from the Linux Lighting Architecture project.
LLA allows DMX sent using various DMX over IP protocols to be converted from one format to another. This enables devices from different manufacturers to talk to each another (for example a Strand Console can send DMX to an Enttec EtherGate).
When combined with a DMX USB Pro, LLA Live can send and receive data from traditional wired DMX networks.
