So I guess the lesson I learned is always use the full DVD???
Or at least be really sure of whats on each version

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

Should definitely be the same.

@scottalanmiller But it is no firewall is running by default
Ah, it is installed but not running.
no, it is not installed at all see my above screen shot..
and wow that post keeps moving down..

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

Yeah, I htought that you were posting it over and over. Then I realized it just woudn't leave teh bottom . Very odd.

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
diffon 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.

Installing firewalld catches a bunch of those.

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 firewalldor addfirewalldto 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
