使用pexpect在虚拟机上侦听端口

Question

我想在python中使用pexpect创建tcplistener（如果有必要）在Windows XP主机上侦听来自Ubuntu的虚拟机中的tcp连接。我真的很感激，如果你们中的一个能够指引我正确的方向。谢谢。

P.S：我在该地区的经验有限，任何帮助将受到欢迎。

Python已经在标准库中提供了一个简单的套接字服务器，该套接字服务器名称为SocketServer。如果你想要的是一个基本的倾听者，看看这个example straight from the documentation：

import SocketServer 

class MyTCPHandler(SocketServer.BaseRequestHandler): 
    """ 
    The RequestHandler class for our server. 

    It is instantiated once per connection to the server, and must 
    override the handle() method to implement communication to the 
    client. 
    """ 

    def handle(self): 
     # self.request is the TCP socket connected to the client 
     self.data = self.request.recv(1024).strip() 
     print "%s wrote:" % self.client_address[0] 
     print self.data 
     # just send back the same data, but upper-cased 
     self.request.send(self.data.upper()) 

if __name__ == "__main__": 
    HOST, PORT = "localhost", 9999 

    # Create the server, binding to localhost on port 9999 
    server = SocketServer.TCPServer((HOST, PORT), MyTCPHandler) 

    # Activate the server; this will keep running until you 
    # interrupt the program with Ctrl-C 
    server.serve_forever()
