This displays the host key in a box and is, hopefully, easier to recognise than a string of numbers. ssh/known_hosts # use Ansible to ping all hosts in inventory # connect as 'ubuntu' user, -k is 'ask for password' $ ansible all -m ping -u ubuntu -k In this case, we will use the inventory file in the local directory and will be connecting to the remote server as root. Ansible connections are done by default with ssh, you can change them using inventory_parameters and also disable host-key-checking. The next time you connect to the remote server, the client compares this key to the one the server supplies. ansible disable host key checking
