      And you've reloaded the firewall with firewall-cmd --reload?

      Still not working

      Just for laughs check the status of setenforce.

      Enforcing

      Try setting setenforce to permissive or disabled for now and test.

      Finally, got the minion to talk to the master. Thanks

      Cool so now you need create an exclusion in setenforce.

      How do I do that? Help the newb here please.

      You'll need to use semanage to allow this.

      semanage port -a -t http_port_t -p tcp 4505-4506

      What would http_port_t translate to? Everything else I understand except that.

      -t specifies a type of service http_port_t is all "type 80 traffic"

        @black3dynamite said in Salt-Minion can't talk to Salt-Master:

        Will you show the command for adding the firewall rules for 4505-5606?
        The reason I'm asking is because if you include --zone=FedoraServer but your active firewall zone is public then that could be the issue.

        I've tried a number of commands

        firewall-cmd --permanent --zone=trusted --add-port=4505-4506/tcp
        firewall-cmd --permanent --zone=default --add-port=4505-4506/tcp
        firewall-cmd --permanent --add-port=4505-4506/tcp

        In that order, but not all at the same time. I reloaded the firewall and retested between each line.

        None of those is expected to work. The default zone is FedoraServer

        Followup question. Is this a security risk? Do they need to be removed? Or they just won't work?

          It's bloating the firewall with rules you don't need.

            yea. . but semanage is so much easier.

              No, they are just ignored.

                setenforce is not a permanent solution. Has soon as you reboot, the setting will revert back to enforcing.

                    Just did the following commands

                    semanage port -a -t http_port_t -p tcp 4505-4506

                    then

                    setenforce enforcing

                    So far, still good.

                      @NerdyDad try restarting and seeing if the issue persists.

                        Oh, no issues. They're still communicating.

                          Dont specify a zone when you run a firewall-cmd and it automatically uses the whatever the current zone is.

                          By the way because your zone is Fedora Server, you installed a full server instance and not a minimal instance.

                          Unless that changed in 29 for minimal.
