Alright, I need some help. If you don't know how to successfully make a server on a Mac with OS X, please do not post. So, I made this server today, but I left the "server-ip=" blank under server.properties

I could connect using localhost, but nothing else. I am trying to find out my IP, but whenever I type in "ifconfig" in terminal, it gives me several ip addresses all starting with "inet" and then a number. I'm not sure which one is mine, or if putting it as my server ip under server.properties would change anything.

I have tried most of the ip's and every time I try to join it says "Permission Denied", unless I connect with localhost.

Any help?
