WWDC is telling me that TCP port 2278 is open, and as you can tell by that link, there is no specific information available on that port. I'm concerned that a malicious program of some time (virus or other) is using that port, and I know there are software apps that allow you to see the endpoint that a process is connecting to. I've seen this feature on various firewalls, but I'm not running a software firewall anymore, so I don't have access to such a feature. Can anyone recommend an app that can tell me what server that process is connecting to via 2278?
