      The current status is that a default minimal install leaves the system exposed. My only guess is that they decided that with the move to a new management interface that they decided that people needed to choose which to install before moving forward no matter what?

        @MattSpeller a minimal install should be minimal install regardless of media used.

        Ah I didn't understand that was the issue, thought you were doing full install from full media

            Should we contact someone about this? Does anyone care? It seems like a huge security problem to me, but I tend to over react 🙂

              Need to know if I need to rebuild all my servers 😞

              Just install the firewalld component, I would assume.

                  Yeah, same here. Very weird that we both got the same glitch and it appeared to be on the client side!

                    @JaredBusch Do you know of anyway to compare the two installs to see what packages are different? It would be interesting to know.

                    rpm -ql >> list

                    On each box. The do a diff on the two lists.

                    [root@testcos7 ~]# rpm -ql
                    rpm: no arguments given for query

                      @MattSpeller I was doing a minimal install from the minimal install media. Regardless, you should get the same result if you do a minimal install from the DVD media. You do not, and this makes me a sad panda.

                        Once I figure out how to get the package lists I will get the differences for you.

                                  Then it all works.

                                  [root@testcos7 ~]# systemctl start firewalld
                                  [root@testcos7 ~]# systemctl enable firewalld
                                  [root@testcos7 ~]#

                                    So if you follow my guides, you will simply need to add yum -y install firewalld or add firewalld to one of the existing lines where i install packages.

                                    and then add the start and enable commands also.

                                    yum -y install firewalld
                                    systemctl enable firewalld
                                    systemctl start firewalld

                                      That is annoying as f[moderated] though.

                                          Why would they include WiFi in the minimal? That doesn't seem to make any sense.
