#Setup a DNS server on your '''balsam''' 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.</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 (outside the '''coniferous.trees.ops.''' zone) to perform DNS lookups among ALL virtual machines within the '''coniferous.trees.ops''' network.</li><li>Any machine in the '''coniferous.trees.ops''' network may use this machine to perform queries of machines outside the network, however it will route all such queries through the DNS server you created in lab #3.</li></ol>
=== Set-up slave Slave Name Server ('''spruce''') ===
Perform the following steps for this section:
#Create a clone virtual machine called '''spruce''' from the '''seedling''' cloning-source. Refer to the table below for '''address''' and '''hostname'''.
#Create a '''regular user''' for this virtual machine using '''your Seneca userID'''.
#Setup a DNS server on your '''balsamspuce''' 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 '''balsam.coniferous.trees.ops'''.</li><li>Only machines within the '''coniferous.trees.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>
