Connection failing between Raspberry Pi and Mac

I have the following

a) a rabbitmq-server and Pika installed on a Mac Yosrmite machine. I have a rabbutmq.config /usr/local/etc/rabbitmq/rabbitmq.config that I have the statement: {loopback_users, []}

b) On the raspberry pi I have pika installed. I also installed the rabbtmq-server.

The send.py and receive.py, using pika, work locally on both machines.

The send from the Mac to the RPi works; but, the send from the RPi to the Mac fails as follows:

Traceback (most recent call last): File "send.py", line 5, in '192.168.1.4')) File "/usr/local/lib/python2.7/dist-packages/pika/adapters/blocking_connection.py", line 339, in init self._process_io_for_connection_setup() File "/usr/local/lib/python2.7/dist-packages/pika/adapters/blocking_connection.py", line 374, in _process_io_for_connection_setup self._open_error_result.is_ready) File "/usr/local/lib/python2.7/dist-packages/pika/adapters/blocking_connection.py", line 395, in _flush_output raise exceptions.ConnectionClosed() pika.exceptions.ConnectionClosed

======================================== My firewall is not enabled in the Mac. There is no errors noted in the server log.

The send.py code is:

#!/usr/bin/env python
import pika

connection = pika.BlockingConnection(pika.ConnectionParameters(
               '192.168.1.4'))
channel = connection.channel()

channel.queue_declare(queue='hello')

channel.basic_publish(exchange='',
                      routing_key='hello',
                      body='Hello World!')
print(" [x] Sent 'Hello World!'")

connection.close()

=========================== I am getting the activity on the port, in both machines: sudo tcpdump port 5672

Any help would be deeply appreciated.

Solution

I found the fix at Open port 5672/tcp for access to RabbitMQ on Mac I deleted the "NODE_IP_ADDRESS=127.0.0.1 " statement in the /usr/local/etc/rabbitmq/rabbitmq-env.conf fiile. This was in addition to the above fix I made to the accessing.
