Login into to one of the grid portal computers - polaris or sierra. Both have AFS home directories so the files are same on both.  The condor software that we will use does not work with AFS so we will make a new directory in the /scratch directory. The next step is to obtain a  Globus proxy certificate using the Globus command grid-proxy-init.  The proxy certificates are good for  a limited amount of time, the default life span is 12 hours. You can use the command grid-proxy-info to view your proxy certificate.
