How to use two HDAs on the same network

Make sure both HDA use different domain names.

You'll need to re-apply this fix on every update of hdactl.

You'll need to run the commands below on both your HDAs.
On your main HDA: replace home.com with your second HDA domain name, and 192.168.1.10 with your second HDA real IP address. On your second HDA: replace home.com with your main HDA domain name, and 192.168.1.10 with you HDA real IP address.
