[Tutor] No connection could be made because the target machine actively refused it (despite mongod running) and unable to insert data into MongoDB

[Arjun Srivatsa]

Hello everyone,

I have been trying to insert data (a 'hello world' string) from PLC into
MongoDB using Python API (which pulls the data from PLC and pushes it into
MongoDB). I have been getting the error message '*line 222, in meth  return
getattr(self._sock,name)(*args) error: [Errno 10061] No connection could be
made because the target machine actively refused it*' despite having mongod
running in the Services background for the code I have written below. Also,
the server IP address on which MongoDB is present is 10.52.124.186 and
address of PLC (which I am using it on my PC) is 10.52.124.135. I am have
tried almost everything to sort it out and yet I haven't got a clue as to
how to get past it. Where am I going wrong?







#!/usr/bin/python


import socket

import socket

import pymongo

from pymongo import MongoClient

import datetime


# Connection to server (PLC) on port 27017

server = socket.socket()

host = '10.52.124.135'

port = 27017


server.connect((host, port))

print server.recv(1024)


server.close


#Connection to Client (Mongodb) on port 27017

IP = '10.52.124.186'

PORT = 27017

BUFFER_SIZE = 1024


client = MongoClient('10.52.124.186', 27017)

db = client.RXMMongoDB


s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

s.bind((IP, PORT))

s.listen(1)


#connections loop

while True:

conn, addr = s.accept()

print 'Connection address:',addr

try:

# read loop

while True:

data = server.recv(BUFFER_SIZE)


if not data:

break

# send to Mongo

mongodoc = { "data": data, "date" : datetime.datetime.utcnow() }

db.AAAA.insert(mongodoc)

finally:

conn.close()
