→Set-up slave Name Server (birch)
#Create a '''regular user''' for this virtual machine using '''your Seneca userID'''.
#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).
