How do I find my server's connection information?

The two important connection information items are the computer’s IP and the port number the server listens at. Both these can be found on the main tab of the server, as shown in the picture. Note that the computer may have multiple IPs (if it has multiple network cards). In that case, they are displayed by holding the mouse over the blue link, and you have to try them one at a time.
