[rabbitmq-discuss] RabbitMq and clustering

[Thomas Sanchez]

- *Open* port 5672, 4369 and the port for rabbit nodes wich is
dynamically
determined BUT it can be fixed by adding this lines:
-kernel inet_dist_listen_min PORT
-kernel inet_dist_listen_max PORT
as argument in file: /usr/lib/rabbitmq/bin/rabbitmq-server.

Sorry for the typo.
