+ -h HOST | --host=HOST Host or IP under test
+ -p PORT | --port=PORT TCP port under test
+ Alternatively, you specify the host and port as host:port

+ -q | --quiet Don't output any status messages
+ -t TIMEOUT | --timeout=TIMEOUT
+ Timeout in seconds, zero for no timeout
+ -- COMMAND ARGS Execute command with args after the test finishes
