How to open firewall port with ansible firewalld task on Centos 7


I have a task in my ansible-playbook script to open TCP port on a remote machine. but when I run my ansible playbook it throws an error. But when i run "firewall-cmd --permanent --zone=public --add-port=1234/tcp" and "firewalld-cmd --reload" I can see port is added in public zone.

Environment Ansible local: OS x El Capitan Ansible remote: AWS Centos 7 minimum version Ansible version: 2.1.1.0 Remote python version: 2.7.5

My task

- name: open management console port
  firewalld: port=1234/tcp zone=public permanent=true state=enabled immediate=yes

The error I am getting

fatal: [X.X.X.X]: FAILED! => {"changed": false, "failed": true, "module_stderr": "", "module_stdout": "Traceback (most recent call last):\r\n  File \"/tmp/ansible_MojhHQ/ansible_module_firewalld.py\", line 605, in <module>\r\n    main()\r\n  File \"/tmp/ansible_MojhHQ/ansible_module_firewalld.py\", line 456, in main\r\n    is_enabled = get_port_enabled_permanent(zone, [port, protocol])\r\n  File \"/tmp/ansible_MojhHQ/ansible_module_firewalld.py\", line 170, in get_port_enabled_permanent\r\n    fw_zone = fw.config().getZoneByName(zone)\r\n  File \"<string>\", line 2, in getZoneByName\r\n  File \"/usr/lib/python2.7/site-packages/slip/dbus/polkit.py\", line 103, in _enable_proxy\r\n    return func(*p, **k)\r\n  File \"<string>\", line 2, in getZoneByName\r\n  File \"/usr/lib/python2.7/site-packages/firewall/client.py\", line 52, in handle_exceptions\r\n    return func(*args, **kwargs)\r\n  File \"/usr/lib/python2.7/site-packages/firewall/client.py\", line 1505, in getZoneByName\r\n    path = dbus_to_python(self.fw_config.getZoneByName(name))\r\n  File \"/usr/lib64/python2.7/site-packages/dbus/proxies.py\", line 70, in __call__\r\n    return self._proxy_method(*args, **keywords)\r\n  File \"/usr/lib/python2.7/site-packages/slip/dbus/proxies.py\", line 50, in __call__\r\n    return dbus.proxies._ProxyMethod.__call__(self, *args, **kwargs)\r\n  File \"/usr/lib64/python2.7/site-packages/dbus/proxies.py\", line 145, in __call__\r\n    **keywords)\r\n  File \"/usr/lib64/python2.7/site-packages/dbus/connection.py\", line 651, in call_blocking\r\n    message, timeout)\r\ndbus.exceptions.DBusException: org.fedoraproject.slip.dbus.service.PolKit.NotAuthorizedException.org.fedoraproject.FirewallD1.config: \r\n", "msg": "MODULE FAILURE", "parsed": false}

Solution

  • dbus.exceptions.DBusException: org.fedoraproject.slip.dbus.service.PolKit.NotAuthorizedException.org.fedoraproject.FirewallD1.config indicates there's some sort of permissions error. The task probably needs to elevate its privileges with become: yes.

    See the become documentation for more details.
