In order to identify yourself to the computer, you'll need to know your UWA PIN number, available by request from the Student Administration desk at Hackett Hall, and you'll also need your student card handy as well. The handouts are located in the fifth tier down in the grey trays near the support desk. However, it is important to note that pretty much any computer with a modem will be able to access the Internet - to some degree. You don't necessarily need foreign access to dial up to UWA - see the next bit. Your Tartarus username and password are used for dialup authentication.
Foreign access is used as an anti-hacking measure, among other things.
Dialing up only falls into this category if you make your Internet connection through another Internet provider, such as Curtin, or iiNet. Foreign access also has its use if you're planning to travel to another country and know in advance which ISP you'll be logging in from. If you're an international student and wish to access Tartarus from home, you need to arrange foreign access with us. This is probably because you've failed to tell your home computer about the UWA Web proxy. You need to do this or your computer won't be able to access outside sites.
