Errno 10061 : 无法建立连接，因为目标机器主动拒绝它（客户端-服务器）

Question

新手上路，请多包涵

我对这些客户端和服务器代码有问题，我不断收到 [Errno 10061] 无法建立连接，因为目标机器主动拒绝它

我在装有 Windows XP SP3 的虚拟机上运行服务器，在 Windows 7 64 位上运行客户端，我的 python 版本是 2.7.3。我想知道的是我应该如何编辑代码以在不同网络上使用客户端和服务器！谢谢！

服务器：

 #!/usr/bin/python           # This is server.py file

import socket               # Import socket module
s = socket.socket()         # Create a socket object
host = '0.0.0.0' # 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
while True:
  msg = c.recv(1024)
  print addr, ' >> ', msg
  msg = raw_input('SERVER >> ')
  c.send(msg);
  #c.close()                # Close the connection

客户：

 #!/usr/bin/python           # This is client.py file

import socket               # Import socket module

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))

while True:
  msg = raw_input('CLIENT >> ')
  s.send(msg)
  msg = s.recv(1024)
  print 'SERVER >> ', msg
#s.close                     # Close the socket when done
