Exposing it
The default guest/guest account only works from localhost, but people disable that. Do not.
Checking it is listening
sudo lsof -i :5672 # macOS, Linux
netstat -ano | findstr :5672 # Windows
nc -zv host 5672 # from elsewhereAn "address already in use" error on a port nothing appears to be holding usually means the socket is in TIME_WAIT rather than that a process has it — the ports reference covers that and the ephemeral range.
