I have created two containers(both using IBM db2 express-c as base image) containing IBM MQ on both.
container_1 has Queue Manager mqm1 listening on port 1414
container_2 has Queue Manager mqm2 listening on port 1415
When I am telnetting from container_1 to container_2 on port 1415 it says connection refused. Similar error occurs while telnetting from container_2 to container_1. For example :
docker exec -it container_1 telnet container_2 1415
But if I change the port on which queue manager is listening to any port number greater than 60000, I am able to telnet to the container on that port.
What is the reason that I am not able to telnet to container using port no 1415?
