socket.error：[Errno 111]连接被拒绝

我想要准备一个原型，并且无法获得连接。我为客户端和服务器都使用OpenSSL。socket.error：[Errno 111]连接被拒绝

#!/usr/bin/env python 

import SocketServer 
import json 
from OpenSSL import SSL 
import os 
import socket 

TERMINATION_STRING = "Done" 

CERTIFICATE_PATH = os.getcwd() + '/CA/certs/01.pem' 
KEY_PATH = os.getcwd() + '/CA/private/key.pem' 

class SSLThreadingTCPServer(SocketServer.ThreadingTCPServer): 
    def __init__(self, address, handler): 
     SocketServer.ThreadingTCPServer.__init__(self, address, handler) 

     ctx = SSL.Context(SSL.SSLv23_METHOD) 

     #ctx.use_privatekey_file(KEY_PATH) 
     #ctx.use_certificate_file(CERTIFICATE_PATH) 
     self.socket = SSL.Connection(ctx, socket.socket(self.address_family, self.socket_type)) 

     print "Serving:", address[0], "on port:", address[1] 



class MemberUpdateHandler(SocketServer.BaseRequestHandler): 
    def setup(self): 
     print self.client_address, "connected" 

    def handle(self): 
     data = "" 
     while True: 
      data += self.request.recv(1024).encode('utf-8').strip 
      if data[-4:] == "Done": 
       print "Done" 
       break 

      dataStrings = data.split(' ') 
      for item in dataStrings: 
       print item 
if __name__ == "__main__": 
    ADDRESS = 'localhost' 
    PORT = 42424 
    HOST = (ADDRESS, PORT) 

    s = SSLThreadingTCPServer(HOST, MemberUpdateHandler) 
    s.serve_forever()

而且客户端：

#!/usr/bin/env python 

from OpenSSL import SSL 
import socket 
import os 

HOST = 'localhost' 
PORT = 42424 
ADDRESS = (HOST, PORT) 

CERTIFICATE_FILE = os.getcwd() + '/CA/certs/02.pem' 

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 

ctx = SSL.Context(SSL.SSLv23_METHOD) 
sslSock = SSL.Connection(ctx, sock) 
sslSock.connect(ADDRESS) #THIS IS WHERE IT FAILS 

items = "this is a test Done" 

sslSock.sendall(items) 

sslSock.close()

最后，错误：

File "SSLClient.py", line 19, in <module> sslSock.connect(ADDRESS) 
File "<string>", line 1, in connect 
socket.error: [Errno 111] Connection refused

任何帮助，将不胜感激。我感觉我错过了一些简单的东西，但我是网络编程的新手。

netstat -tpn输出，而在服务器运行：

首先，你的端口号太高。端口号从0-65535。 – Neal

将端口号更改为范围内并仍然出现错误。 – Lunchbox

你在哪个操作系统上运行，服务器运行时'netstat -tpn'的输出是什么？你有没有配置防火墙？ – phihag

当您在子类中调用

SocketServer.ThreadingTCPServer.__init__(self, address, handler)

，该ThreadingTCPServer将创建一个套接字，并执行绑定/听。之后，你做

self.socket = SSL.Connection(ctx, socket.socket(self.address_family, self.socket_type))

创建您的SSL套接字。这个套接字虽然没有绑定。你需要做的是调用父类的构造函数是不同的：

SocketServer.ThreadingTCPServer.__init__(self, address, handler, bind_and_activate=False)

注意最后一个参数。这将阻止超类绑定它创建的套接字。然后，在创建套接字后，请致电self.server_bind()和self.server_activate()，以便您创建的套接字已正确设置。

总之，试着改变你的服务器：

class SSLThreadingTCPServer(SocketServer.ThreadingTCPServer): 
    def __init__(self, address, handler): 
     SocketServer.ThreadingTCPServer.__init__(self, address, handler, bind_and_activate=False) 

     ctx = SSL.Context(SSL.SSLv23_METHOD) 

     #ctx.use_privatekey_file(KEY_PATH) 
     #ctx.use_certificate_file(CERTIFICATE_PATH) 
     self.socket = SSL.Connection(ctx, socket.socket(self.address_family, self.socket_type)) 
     self.server_bind() 
     self.server_activate() 


     print "Serving:", address[0], "on port:", address[1]

谢谢，这清除了连接被拒绝的问题。现在我无法完成握手。进展！ – Lunchbox

在Debian 4.7.2-5 x64上没有适用于我。打电话给'netstat -tpn'没有显示任何感兴趣的东西 –
