linux下最简单的socket客户端报错

同样的程序，同样的IDE，同样的python2.7，在windows下可以正常运行，linux下就不行！为什么呢？ server没有问题，就client有问题！

1. #!/usr/bin/env python
   
2. import socket
   
3. import time
   
4. s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
   
5. s.connect(('localhost', 8002))
   
6. time.sleep(2)
   
7. s.send("1")
   
8. print s.recv(1024)
   
9. s.close()
