设备：  
自己的笔记本电脑和jetsonnano一台+显示屏  
同一个wifi 查看ubuntu和windows的ip地址

注意：windows和ubuntu关闭防火墙！

## ubuntu作为服务端，windows客户端传输数据和文件： ##

服务端用python（jetsonnano)  
客户端用java写:(自己笔记本）  
服务端接收到文件并输出：

    port = 8888               # 设置端口号
     
    s.connect((host, port))
    s.send('yes!'.encode('utf-8'))	#发送 TCP 数据，将 string 中的数据发送到连接的套接字。返回值是要发送的字节数量，该数量可能小于 string 的字节大小。
    
    s.close()
