      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

      Was it SELinux?

      I think that was part of it. The other part as not to specify a port to the server in the minions config file.

        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.

              Here is a decent man page and examples.

              Since you're allowing ports through you'd want to do that.

                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.

                  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.

                              No, they are just ignored.

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

                                  setenforce is not a permanent solution. Has soon as you reboot, the setting will revert back to enforcing. Unless you disable it permanently, which isn't recommended.

                                    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.

                                            Weird.. I didn't have to do anything with SELinux to get it working:
