11 * Description:
12 *
13 * This plugin will attempt to open an FTP connection with the host.
14 * Successul connects return STATE_OK, refusals and timeouts return
15 * STATE_CRITICAL, other errors return STATE_UNKNOWN. Successful
16 * connects, but incorrect reponse messages from the host result in
17 * STATE_WARNING return values.
