Errno 10061 : No connection could be made because

Question

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.

Answer 1

Hint: actively refused sounds like somewhat deeper technical trouble, but...

...actually, this response (and also specifically errno:10061) is also given, if one calls the bin/mongo executable and the mongodb service is simply not running on the target machine. This even applies to local machine instances (all happening on localhost).

➪ Always rule out for this trivial possibility first, i.e. simply by using the command line client to access your db.

See here.

Answer 2

Using the examples from: https://docs.python.org/3.2/library/socketserver.html I determined that I needed to set the HOST port to the machine I had the server program running on. So TCPServer on 192.168.0.1 HOST = TCPServer IP 192.168.0.1 then I had to set the TCPClient side to point to the TCPServer IP. So the TCPClient HOST value = 192.168.0.1 - Sorry, that's the best I can describe it.

Answer 3

the short term solution is to use the default iis host and port normally 120.0.0.1 and 80 respectively. However am still looking for a more versatile solution.

Answer 4

if you have remote server installed on you machine. give server.py host as "localhost" and the port number. then client side , you have to give local ip- 127.0.0.1 and port number. then its works

Answer 5

I was facing a similar problem when I was calling REST API using python library and what I found that my server was going into sleep mode which was leading to this. As soon as I logged in to the server via Remote Desktop Connection, my API call used to work.

Answer 6

The solution is to use the same IP and Port number in both client and server. Try, in client to use TCP_IP = 'write the ip number here' TCP_PORT = writ the port number here s.connect((TCP_IP, TCP_PORT))
