This guide will show you how to access a computer located on your home network from outside of your local area network. For the purposes of this guide, let’s assume we are trying to access a HOME SERVER such as a Mac Mini located on your home WiFi router. The home computer could just as easily be a Ubuntu, or similarly flavored Linux machine. The first thing that we will need to do is determine your home IP address, and then we will setup port forwarding on your wireless router.

Having trouble accessing a favorite Web site? Perhaps the site was taken offline, or the computer hosting it is down for maintenance. However, the cause could be something more mysterious. At any given moment, a portion of Internet traffic ends up being routed into information “black holes.” These are situations where advertised paths exist to the destination, but messages - a request to visit a Web site, an outgoing e-mail - get lost along the way.

Hubble is a system that operates continuously to find persistent Internet black holes as they occur.
