socket.error:[Errno 111]连接被拒绝

标签: python openssl tcpserver socketserver

我正在尝试准备原型并且无法获得连接。我正在为客户端和服务器使用OpenSSL。

#!/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()

客户:

#!/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。我觉得我错过了一些简单的东西,但我不熟悉网络编程。

服务器运行时输出

netstat -tpn

致电时

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

在您的子类中,ThreadingTCPServer将创建一个套接字并执行bind / listen。在那行之后你做

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

创建SSL套接字。虽然这个套接字没有绑定。你需要做的是以不同的方式调用超类的构造函数:

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,请调用self.server_bind()self.server_activate(),以便正确设置您创建的套接字。

总之,请尝试将服务器更改为:

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]
