Let's say I have a couple of separate Linux NSD servers. How can I make the master server share changes with the slave servers?
NSD appears to have this functionality. It can declare zones as master or slave. I'm pretty sure I understand how to set up the communication in the config files.
What are the commands necessary after a zone update on the master server to propagate the changes to the slaves? Is it entirely automatic once NSD's cache is updated, or is some intervention necessary?
Edit: Solved, please remove.
