    port [port..] 设置扫描的端口，用逗号分隔。
        默认：21, 22, 23, 25, 80, 135, 137, 139, 445, 1433, 1502, 3306, 3389, 8080, 9015
        example：port 21,23,25
        example: port 1000..2000
        example: port 80,443,1000..1500
    scan [IP] 扫描某一IP地址
        example: scan 192.168.1.5
    search [IP begin]-[IP end] 扫描某一IP段
        example: search 192.168.1.1-192.168.1.100
    time [timeout] 设置超时时间，默认为3秒
        example: time 5
