→PART 2: DNS OVERVIEW
* Understand the principles of how DNS works.
* Set up an authoritative DNS server.
* Test your DNS server to confirm that it works as expected.
* Configure an operating system to use a specific DNS server.
= PART 1: PREREQUISITES =
DNS is technically not a required part of the internet, but effectively it's indispensable for nearly all services of every sort on the internet. We'll spend a couple of weeks on topics related to DNS.
Read sections 1-3 13 from the [https://en.wikibooks.org/wiki/Communication_Networks/DNS Wikibooks DNS page].
= PART 3: YOUR OWN DNS SERVER =
# Once you are certain that the ''named'' service had started and runs without errors, then set it to '''start automatically''' (i.e. enable the named service) when this virtual machine boots.
# Now that you know the service works, '''add the resource records necessary for it to provide forward lookups of the other machines in your virtual network''' (hint: You should only need two more records) and restart the service.
# Test the server on lin2 using the dig command, for example:<source>dig c7host.andrew.ops @192.168.210.12</source>
