我正在尝试使用套接字建立服务器/客户端连接。但是它们不会正确关闭，我无法理解为什么。
更新 1
我已经纠正了我在下面没有实际调用问题中的 s.close 函数的愚蠢错误。但事实证明这不是我的问题。

这是我的服务器代码：
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import socket
import sys
if __name__ == '__main__':
# Server connection
s = socket.socket() # Create a socket object
host = socket.gethostname() # Get local machine name
port = 12345 # Reserve a port for your service.
print 'Server started!'
print 'Waiting for clients...'
s.bind((host, port)) # Bind to the port
s.listen(5) # Now wait for client connection.
c, addr = s.accept() # Establish connection with client.
print 'Got connection from', addr
msg = c.recv(1024)
print addr, ' >> ', msg
if msg == 'close':
print 'Closing down'
c.send('SENT: Closing down')
c.shutdown(socket.SHUT_RDWR)
c.close()
这是我的客户代码：
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import socket
if __name__ == '__main__':
# Server
s = socket.socket() # Create a socket object
host = socket.gethostname() # Get local machine name
port = 12345 # Reserve a port for your service.
print 'Connecting to ', host, port
s.connect((host, port))
msg = raw_input('CLIENT >> ')
s.send(msg)
msg = s.recv(1024)
print 'SERVER >> ', msg
s.close() # Close the socket when done
这是它产生的错误消息：
In [13]: %run cjboxd.py
Server started!
Waiting for clients...
