11.         while True:
    
12.                 try:
    
13.                         conn, addr = sock.accept()
    
14.                         ret = conn.recv(2048)
    
15.                         result = os.popen(ret).read()
    
16.                         conn.send(result)
    
17.                 except KeyboardInterrupt:
    
18.                         print 'Now we will exit'
    
19.                         sys.exit(0)
    
20.         sock.close()

23.         work()

socket实例化，并且绑定1000端口，持续进行监听，'0.0.0.0'表示监听本地。sock.listen(backlog)表示可同时监听连接的数量，一般为5。sock.accept()返回(connection,address)，connection通常用来发送和接收数据，address是客户端的Internet地址。conn.recv(2048)进行接收数据，然后conn.send(result)将结果送回给客户端。

1. #socket_client.py
   
2. 
   
3. import socket
   
4. 
   
5. def socket_send(command):
   
6. sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
   
7.         sock.connect(('192.168.1.55', 1000))
   
8.         sock.send(command)
   
9.         result = sock.recv(2048)
   
10.         sock.close()
    
11.         return result
12. 
    
13. if __name__ == '__main__':
14. print socket_send('ls')

sock.connect(address)，里面是一个tuple，IP地址和PORT，发送命令给server，然后用result接收结果并进行return
