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

      Still not working

      @DustinB3403 said in Salt-Minion can't talk to Salt-Master:

      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.

            Here is a decent man page and examples.

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

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

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

                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

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

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

                              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.

                                      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.
