      @MattSpeller Minimal should be Minimal regardless of media used.

      Should definitely be the same.

          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 🙂

                  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.
