module: ping
version_added: historical
short_description: Try to connect to host, verify a usable python and return V(pong) on success
description:
  - A trivial test module, this module always returns V(pong) on successful
    contact. It does not make sense in playbooks, but it is useful from
    C(/usr/bin/ansible) to verify the ability to login and that a usable Python is configured.
  - This is NOT ICMP ping, this is just a trivial test module that requires Python on the remote-node.
  - For Windows targets, use the M(ansible.windows.win_ping) module instead.
  - For Network targets, use the M(ansible.netcommon.net_ping) module instead.
options:
  data:
    description:
      - Data to return for the RV(ping) return value.
      - If this parameter is set to V(crash), the module will cause an exception.
    type: str
    default: pong
