Prerequisites: Running iLat on a Unix Desktop Machine

• FTOOLS (see NASA's HEASARC: Software)
• Secure Shell (SSH) for Unix (see SSH for Unix)
• CVS: Linux Machines (see instructions below)

CVS: Linux Machines

1. The Concurrent Versions System (CVS) utility should already be installed on your system. To verify that it is installed, enter a command such as cvs -v from the command line.

If CVS is not installed on your system, contact your system administrator to have it installed.

2. Create the following environment variables so that you have access to the GLAST cvs respository:

Troubleshooting Tip: If your userid on your local machine is different from your userid for SLAC, you must specify your SLAC userid.

For example, if your SLAC userid is mySLACid then, in the second export command above:

:ext:centaurusa.slac.stanford.edu

   should be replaced with:

:ext:yourAccountName@centaurusa.slac.stanford.edu:/nfs/slac/g/glast/ground/cvs

3. To verify that you can access the GLAST CVS server, issue a query.

For example, the start of output for a cvs rlog command on a module
in the GLAST repository:

If the command does not produce a reasonable response, make sure that the environment variables are set correctly, and that ssh was set up as specified by the instructions in Basic Prerequisites.
