We may need to have a simple bash service which launches a server listening on the port and then launches a client to connect to that port. There is this description of nmap. There is also this description. Since the ephemeral port range is very large, we only need to verify that a couple of the ports are open - a sampling.
Output of the pre-flight checks. This will appear after we test access to the repositories.
