      So explain to me why you skipped turning on networking in the GUI?

      In my experience with novice users, you avoid an entire host of issues if you additionally setup networking on that installation screen.

      It is not like the desired networking information will change between the GUI install and time you first login.

            Good point, I'm modifying it now.

              Here is the thread where each of the lessons is coordinated. Kind of the "Table of Contents."

                I do realize, that it is not hard to setup networking in CentOS, but if your target is novice users, I think enabling networking in the GUI is the best thing to do. Because then you can drop straight to SSH next.

                        One other thing that trips people up is it doesn't enable the NIC by default. If you don't configure it and enable autloading, there is no networking until you configure the ifcfg file.

                          That is what I just said. Turn it on in the GUI during initial config.

                                It is partially written and open on my desktop (I write in Atom then post over to keep my browser from crashing and losing it.) Hopefully later today.

                                  If anyone has specific topic ideas, feel free to share. I have covered this material for decades but have never taught someone from the ground up and so am trying to figure out how to teach, and cover, the basic stuff both for a beginner and for someone coming from a Windows Admin background and not have huge gaps making things hard to understand.

                                    @scottalanmiller Logging in using SSH with public/private keypairs instead of username/password to increase security might be a good topic or subtopic. Enjoying what has been posted so far!

                                      That's definitely coming. SSH and key management will be major topics.

                                          Something that I'd like a better grasp on is how the mindset is different. Coming from a decade+ of Windows admin work, some of the things that others call easy, or assume that it should be understood, I don't get. There are many examples, but today I ran across an irritating one: installing RAID drivers. In Windows, this is either easy, or undoable. In Linux (during install) it appears to require a significant background. "Just compile from source." is not an easy answer for me at this point because I don't even know where on my mental grid to fit that, much less how to do it for the variety of needed scenarios.

                                            Wait. What? You shouldn't really be installing RAID drivers at least not to my knowledge. As far as the OS is concerned that is just raw disk right?
