#Setup a DNS server on your '''elm''' virtual machine with noting the following items below:<ol type="a"><li>This virtual machine will be the '''Master DNS server'''.</li><li>This machine will provide '''forward''' and '''reverse''' lookups of ALL virtual machines in the '''coniferous.trees.ops''' zone, including resource records for virtual machines that do not currently exist, but will exist when you perform your assignment #2.</li><li> Make certain to include an '''MX record''' for your admin e-mail contact: '''yoursenecaid@coniferous.trees.ops'''</li><li>This machine will allow other machines to perform DNS lookups among ALL virtual machines within the '''coniferous.trees.ops''' network (i.e. recursive lookups).</li><li>Only this Master Name Server will be allowed to transfer zone files from this machine.<br><br></li></ol>

#As you will now have a functioning primary DNS server, modify your network configuration file to specify its new IPADDR.

#Setup a DNS server on your '''elm''' virtual machine with noting the following items below:<ol type="a"><li>This virtual machine will be the '''Slave DNS server''' (in case the Master Name Server goes down).</li><li>This virtual machine will obtain its zone files by copying them from the Master Name Server.</li><li>This Slave DNS server will check for updated records from the Master DNS server every day. If the initial attempt fails, then it will attempt every hour until it succeeds.</li><li>This machine will provide '''forward''' and '''reverse''' lookups of ALL virtual machines in the '''coniferous.trees.ops''' zone, the zone files for which will be obtained from '''elm.coniferous.trees.ops'''.</li><li>Only machines within the spiral.galaxies.ops domain will be allowed to query this machine.</li><li>This machine will not provide recursive lookup capabilities for any machines.<br><br></li></ol>

#As you will now have a functioning secondary DNS server, modify your network configuration file to specify its new IPADDR. You will also have to add another IPADDR for your DNS server you setup in lab #1 to allow DNS queries from your virtual machines to outside server (TIP: You cannot use your '''primary''' or '''secondary''' DNS option).
