unable to restart iptables from ansible ( Interactive authentication required)

Question

How to restart iptables service from Ansible (in order to reload config file /etc/sysconfig/iptables)

I have handler restart iptables defined as

service: name=iptables enabled=yes state=restarted

But it produces following error message:

fatal: [xx.xx.xx.xx]: FAILED! => {"changed": false, "failed": true, "msg": "Failed to stop iptables.service: Interactive authentication required.\n Failed to start iptables.service: Interactive authentication required.\n"}

I am working with CentOS Linux release 7.2.1511 (Core)

Answer 1

I was not running my handler command as root. If handler contains become: yes then handler works fine.

- name: restart iptables
  become: yes
  service: name=iptables enabled=yes state=restarted

Another way of refreshing iptables configuration, without restarting it is

- name: reload iptables
  become: yes
  shell: iptables-restore <  /etc/sysconfig/iptables
