If I read between the lines correctly, the faster operation happens when youe add that line to /etc/hosts on your Ansible machine, not all the target machines. If that's true, it appears an Ansible process running on the Ansible machine is triggering a forward lookup of the hostname (i.e., trying to obtain the IP address) as connections to target nodes are initiated. I'm not familiar with Red Hat based distros, so I don't know if if could be an ssh client config thing, or an ssh agent config thing, or a paramiko thing, or something else. -Greg -- You received this message because you are subscribed to the Google Groups "Ansible Project" group.
