Server configuration - not just localhost

[Matthew Baynham]

Hi

I'm trying to setup my first RabbitMQ server, I have some python code that sends a message to localhost and it gets to the server, that is good.

I want to be able to use the code to send a message from another machine.

So I use the exact same python code to send a message and instead of localhost I have the IP address 172.17.0.1 which is the machine.  (I've checked the IP address this is correct.)

(Note: At the moment everything is on the same computer but I want to be able to connect from other computers.)

But it doesn't work for IP address 172.17.0.1

What do I need to check with the server configuration?

Or is there something else I'm missing?

This is my Python:

#!/usr/bin/env python
import pika

def send_to_queue(message):
    credentials = pika.PlainCredentials('test001', 'Gs3g!eJ3rb4v')
    #credentials = pika.PlainCredentials('guest', 'guest')
    #parameters = pika.ConnectionParameters('localhost', 5673, '/', credentials)
    parameters = pika.ConnectionParameters('172.17.0.1', 5673, '/', credentials)
    #parameters = pika.ConnectionParameters('amqp://172.17.0.1', 5673, '/', credentials)
    connection = pika.BlockingConnection(parameters)
    channel = connection.channel()
    channel.queue_declare(queue='hello')
    channel.basic_publish(exchange='', routing_key='hello',body=message)
    connection.close()
    return "Message Sent!  "

send_to_queue("helloooo")

This is what I get when I run it.
