I'm novice in OS X (mountain-lion) world, and learning how to use this system.

Now, I have a problem about network. I run a application that try to connect its update server, but I got "connect to update server timeout" message.

I think my network works well, so I want to know which update server that the application try to connect to, the request address.

So, how can I view connect request of this application, especially update server address. I try to use netstat tool in network utility, but didn't find information I need.

Could you teach me to use a tool (freeware) or give me a command in terminal?

Thank you!
