== OBJECTIVE & PREPARATION==
In OPS235, you learned how to configure a virtual private network for the '''centos1''', '''centos2''' and '''centos3''' virtual machines. All of the virtual machines in the OPS335 course for labs and assignments will be CLI or "text-based" (just as centos3 was CLI for your OPS235 labs). All of the services that we are configuring in this course '''require a working network connection'''; therefore, it is very important that you know how to configure a network connection for your VMs, whether via command line for trouble-shooting purposes, or to create a persistent (permanent) network connection that uses static IP address (as opposed to DHCP).
This lab is a <u>review</u> of the material from labs 6 ( [http://zenit.senecac.on.ca/wiki/index.php/OPS235_Lab_6_-_CentOS7#Part_4:_Configuring_VM_Network_Setup_via_Command_Line_.28centos3.29 CLI Network Configuration] ), but will also show other commands in the process.
