In OPS235, you learned how to configure a virtual private network via graphical applications for the '''centos1''' and , '''centos2''' machines. In the previous lab, you have created and cloned VMs that are text-based only ('''like centos3''')virtual machines. All of the virtual machines in this course will be CLI (text-based (), just like as centos3 was CLI in your OPS235) for this courselabs. 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 set configure a network connection for your VMs, whether via command line for trouble-shooting purposes, or to create a persistent (preferable configurepermanent) a network connection that uses static IP address, default gateway, (as well as your DNS server from the command lineopposed to DHCP).
