socket.error: [Errno 111] Connection refused
I am trying to get a prototype ready and am having trouble getting a connection. I'm using OpenSSL for both the client and the server.
#!/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()
And the client:
#!/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()
Finally, the error:
File "SSLClient.py", line 19, in <module> sslSock.connect(ADDRESS)
File "<string>", line 1, in connect
socket.error: [Errno 111] Connection refused
Any help would be appreciated. I get the feeling I'm missing something simple, but I am new to network programming.

Answer
When you call
SocketServer.ThreadingTCPServer.__init__(self, address, handler)
in your subclass, the ThreadingTCPServer will create a socket and do the bind/listen. After that line you do
self.socket = SSL.Connection(ctx, socket.socket(self.address_family, self.socket_type))
to create your SSL socket. This socket does not get bound though. What you need to do is call the super class' constructor differently:
SocketServer.ThreadingTCPServer.__init__(self, address, handler, bind_and_activate=False)
Note the last argument. This will prevent the superclass from binding the socket that it creates. Then, after you create your socket, call self.server_bind() and self.server_activate() so that the socket you created is properly setup.
In summary, try changing your server to:
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]
