So for example:

This looks like the port simply isn't listening. But it really is. The issue is that the docker container lacks a netstat binary and doesn't have net-tools installed.

I would expect to see the exception raised from mixlib-shellout here or some other error indicating "netstat: command not found" more or less, but it seems like inspec is silently swallowing the error.

(for super bonus points you could also do pure-ruby parsing of the /proc filesystem on linux and avoid the external netstat binary dependency, but i don't really expect that...)
