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. | ||
