Python – Errno 10061 : No connection could be made because the target machine actively refused it ( client – server )

pythonsockets

I have a problem with these client and server codes, I keep getting the [Errno 10061] No connection could be made because the target machine actively refused it

I'm running the server on a virtual machine with Windows XP SP3 and the client on Windows 7 64bit, my python version is 2.7.3. What I want to know is how should I edit the code to use the client and server on different networks! Thanks!

server :

#!/usr/bin/python           # This is server.py file

import socket               # Import socket module
s = socket.socket()         # Create a socket object
host = '0.0.0.0' # Get local machine name
port = 12345                # Reserve a port for your service.


print 'Server started!'
print 'Waiting for clients...'

s.bind((host, port))        # Bind to the port
s.listen(5)                 # Now wait for client connection.
c, addr = s.accept()     # Establish connection with client.
print 'Got connection from', addr
while True:
  msg = c.recv(1024)
  print addr, ' >> ', msg
  msg = raw_input('SERVER >> ')
  c.send(msg);
  #c.close()                # Close the connection

client :

#!/usr/bin/python           # This is client.py file

import socket               # Import socket module

s = socket.socket()         # Create a socket object
host = socket.gethostname() # Get local machine name
port = 12345                # Reserve a port for your service.

print 'Connecting to ', host, port
s.connect((host, port))

while True:
  msg = raw_input('CLIENT >> ')
  s.send(msg)
  msg = s.recv(1024)
  print 'SERVER >> ', msg
#s.close                     # Close the socket when done

PS : code is from internet.

10061 is WSAECONNREFUSED, 'connection refused', which means there was nothing listening at the IP:port you tried to connect to.

There was a firewall product around the year 2000 that issued refusals instead of ignoring incoming connections to blocked ports, but this was quickly recognised as an information leak to attackers and corrected or withdrawn.
