cannot start containers

[ghost]

I am running the splunknbox script on an Ubuntu 16.04 server with docker-ce installed in Vmware workstation 12. I am unable to build the splunk containers as I get an error message stating that docker cannot bind to address xxx.xxx.xx.x:9997 cannot assign address.

All my research has shown that this is an indication that the port is being used and to select another port, however I do not have any other containers running, and nor do I have anything on the host running. It should be noted that the error picks a random IP address from the /24 that is selected to use in the start and end alias portions of the script.

Any assistance would be appreciated.
