Python SSLError：客户端错误(EOF发生违反协议),服务器端错误(SS

首先,服务器代码如下所示：

class ThreadedTCPServer(SocketServer.ThreadingMixIn,SocketServer.TCPServer):

    def __init__(self,server_address,RequestHandlerClass,client_manager,recv_queue):
        SocketServer.TCPServer.__init__(self,bind_and_activate=True)

         <snipped out extra code>

class ThreadedTCPRequestHandler(SocketServer.BaseRequestHandler):

    def setup(self):

        while True:
            try:
                print 'trying to wrap in ssl'
                self.request = ssl.wrap_socket(self.request,certfile=(os.getcwd() + '/ssl_certs/newcert.pem'),keyfile=(os.getcwd() + '/ssl_certs/webserver.nopass.key'),server_side=True,cert_reqs=ssl.CERT_NONE,ssl_version=ssl.PROTOCOL_TLSv1,do_handshake_on_connect=False,suppress_ragged_eofs=True)
                break

            except Exception,ex:
                print 'error trying to wrap in ssl %s' % ex

    def handle(self):
        # Display message that client has connected
        print 'r[*] Received connection from %s:%sr' % (self.client_address[0],self.client_address[1])

        while self.stopped() == False:
            recv_msg = self.request.read(1024)

            if recv_msg == '':
                self.stop.set()
                server.recv_queue.put(recv_msg)
                break
            else:
                server.recv_queue.put(recv_msg)

        if self.stopped():
            print '[!] Received STOP signal from %s:%s; Exiting!' % (self.client_address[0],self.client_address[1])

其次,这是客户端代码,我在其中设置通过需要身份验证的代理连接所需的信息：

class proxyCommsHandler():

    def __init__(self,user,password,remote_host,remote_port,list_of_proxies):
        # information needed to connect
        self.user = 'username'
        self.passwd = 'password'
        self.remote_host = 'remote_host_ip'
        self.remote_port = 8008
        self.list_of_proxies = [['proxyserver.hostname.com',8080]]

        # setup basic authentication to send to the proxy when we try to connect
        self.user_pass = base64.encodestring(self.user + ':' + self.passwd)
        self.proxy_authorization = 'Proxy-authorization: Basic ' + self.user_pass + 'rn'
        self.proxy_connect = 'CONNECT %s:%s HTTP/1.1rn' % (self.remote_host,self.remote_port)
        self.user_agent = "User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:7.0.1) Gecko/20100101 Firefox/7.0.1rn"
        self.proxy_pieces = self.proxy_connect + self.proxy_authorization + self.user_agent + 'rn'

现在,这里是我最初连接到代理的地方,在那里我没有错误(我得到’200’状态代码)：

self.proxy = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
self.proxy.connect( (proxy_host,proxy_port) )
self.proxy.sendall(self.proxy_pieces)
self.response = proxy.recv(1024)

这是客户端失败的地方(我认为).我尝试使用self.proxy并将其包装在SSL中,如下所示：

sslsock = ssl.wrap_socket(self.proxy,server_side=False,do_handshake_on_connect=True,ssl_version=ssl.PROTOCOL_TLSv1)

这是我在客户端上看到的错误：

Traceback (most recent call last):
    File "C:Python27pyrevshell.py",line 467,in <module>
        proxyCommsHandler(None,None,list_of_proxies).run()
    File "C:Python27pyrevshell.py",line 300,in run
        ssl_version=ssl.PROTOCOL_TLSv1)
    File "C:Python27libssl.py",line 372,in wrap_socket
        ciphers=ciphers)
    File "C:Python27libssl.py",line 134,in __init__
        self.do_handshake()
    File "C:Python27libssl.py",line 296,in do_handshake
        self._sslobj.do_handshake()
    SSLError: [Errno 8] _ssl.c:503: EOF occurred in violation of protocol

客户端确实连接,如此处的输出所示：

trying to wrap in ssl
[*] Received connection from x.x.x.x:47144
[*] x.x.x.x:47144 added to the client list

但接下来是一个例外：

----------------------------------------
Exception happened during processing of request from ('x.x.x.x',47144)
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py",line 582,in process_request_thread

      return self._sslobj.read(len)
SSLError: [Errno 1] _ssl.c:1348: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
----------------------------------------

虽然我意识到这听起来像一个基于抛出的异常的明显问题,但有趣的部分是：

>我最初通过代理成功连接,如上所示
>我可以成功连接同一代理后面的Web浏览器,并且不会抛出任何异常;我可以将数据传递给浏览器
>我在服务器端和客户端尝试了不同的SSL协议版本,如Python documentation中的表所示;它每次都在客户端出错

我在连接的两端都使用了Wireshark.使用普通浏览器并连接到服务器时,我看到整个SSL握手和协商过程,一切运行顺利.

但是,当我使用上面显示的客户端时,一旦我连接它,我看到客户端发送客户端Hello消息,但然后我的服务器发送一个RST数据包来终止连接(我还没有确定这是否是之前或抛出异常后).

我再次道歉,但我迫切需要专家建议.
