Making Persistent (Permanent) Network Setting Changes
<ol>
<li value="7">Edit the '''ifcfg-''interfacename''''' file for each of your VMs to use a static IP address (refer to previous OPS235 lab on networking: [ [http://zenit.senecac.on.ca/wiki/index.php/OPS235_Lab_6_-_CentOS7#Part_4:_Configuring_VM_Network_Setup_via_Command_Line_.28centos3.29 Network Config - CLI] ].<br> You should be configuring the BOOTPROTO ('''static''' instead of dhcp), IPADDR, NETMASK, GATEWAY, and DNS1 for this file. Note the following information for this setup:<ul><li>Set your IPADDR for each VM with the following rules:<ol type="a"><li>Your IPADDR's third octet will use the last 2 digits in your student number.</li><li> Make certain that the 4th octet for your VMs does not start with '''1''' since that is reserved for the '''GATEWAY''' or '''DNS'''.<br>For example, the forth octets: '''2 for vm1''', '''3 for vm2''', and '''4 for vm3'''.</li></ol></li><li>Don't forget to set the default gateway and DNS server for your VMs. You can use your host's IP address as a DNS server<br>(''libvirt'' will proxy the requests to the real DNS server).</li><li> You can refer to your previous lab to obtain information for setup of these options: [ [http://zenit.senecac.on.ca/wiki/index.php/OPS335_Installation_Lab#Configuring_a_VM_host Configuring a VM Host] ]<br><br></li></ul><li>Make note of the files used and entries required and note them in your lab log-book.</li><li>Save your editing session, and then restart each VM and run the following command to ensure they still have the network configuration you set:</liul></olli::'''ping''' (what is the purpose of this command?). Try to ping matrix and google from your host machine. <br>Try to ping matrix and google from each of your VM's to ensure you can reach the outside world.::</li><li>'''ssh''' (into another server, like Matrix) </li></ul></ol>
