Perhaps I don't even need to do this, so, if I don't, fine.
I have a machine with one IP. I decided to add a second nic and IP and move all the domain and services EXCEPT the DNS to the new nic.
I successfully configured the nic and added the IP. Then I went to Addresses and Networking -> Change IP Addresses. I selected "all servers" and entered the IP I want to change them to.
When I tried to load the web pages from any of the formerly working domains, I just get an empty directory listing in the browser.
I was able to successfully set the IP back to the old one... but I'm not sure what's up with that. What am I doing wrong?
How can I move the three domains and all the services to the new nic's IP address, and leave only the name server on the old nic? Is it even worth doing?
