View source for Slave mode

It's possible to have two or more HDAs in one network.

One of them would (optionally) be the DHCP server, or "master".

The rest would be "slaves" to that one. The idea is that each one of the rest of the slaves should have their DHCP server turned off, so that it does not conflict with the master.

Then the slaves can be "chained" .. by using:

      hda-change-dns IP-OF-THE-MASTER IP-OF-THE-MASTER

So that they use the master for DNS resolution, therefore having visibility to the apps in that one.
