Name: email.organicbrownsugar.com
Address: 192.10.1.10
If this is what you see we can be almost sure our DNS server is working well. Now test some of the other names we created before such as
Name: email.organicbrownsugar.com
Address: 192.10.1.10
Aliases: imap.organicbrownsugar.com
Great! You can now call yourself a BASIC-DNS-LINUX-INSTALLER. But now let's see if our reverse lookup zones work as well by typing:
192.10.1.244
Now if you're your really lucky and didn't make any typo's you should most likely see
Server: email.organicbrownsugar.com
Address: 0.0.0.0
Name: netikus.organicbrownsugar.com
Address: 192.10.1.244
Before we make an end to our endless DNS verifications, we make sure that email servers will have use of our DNS server by finding a mail exchanger (MX) for our domain @organicbrownsugar.com by typing:
set query=mx
organicbrownsugar.com
This should yield
organicbrownsugar.com preference = 10, mail exchanger = email.organicbrownsugar.com
organicbrownsugar.com nameserver = email.organicbrownsugar.com
email. organicbrownsugar.com internet address = 192.10.1.10
Okay now, if all this worked our DNS server is configured correctly for stand alone operation and we can type exit to leave nslookup. Please note that we do not have a secondary server at this time which inevitably results in absolutely now redundancy. But since we only have one server for all our services anyways it doesn't really matter for our scenario. You can say a little prayer to the hardware god before you go to bed tonight.
Now the only thing that's missing to make our name resolution life wonderful is to make our DNS daemon start automatically after every boot.
