Unable to Connect to localhost:8000

I am trying to use Sage by SSH into my university's computer system. I succeeded in getting into the computer which has Sage installed on it. However, when I try to actually run the program, I run into problems. I type

sage -n

and get the following

| Sage Version 4.5.3, Release Date: 2010-09-04 |

When I try to open http://localhost:8000 in an in internet window, I get "Unable to Connect" from Firefox, and a similar message when I try to open it in Internet Explorer.

I'm very new to Sage and Linux, and have no idea what's going wrong here. I haven't been able to find any instructions on how to run Sage through ssh, so I'm wondering if I'm missing a step somewhere.

Thanks.
