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

            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?

              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 🙂

                    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.
