The University of Chicago has a Mathematica license that covers all Computer Science Department computers. Before you can use Mathematica, you should make sure the license is configured. Here are two ways that should work:
mathematica(this requires X), and choose the "Network License" option. Type in
license.uchicago.eduand hit OK.
Run these commands at the shell:
mkdir -p ~/.Mathematica/Licensing
echo '!license.uchicago.edu' > ~/.Mathematica/Licensing/mathpass
