Your home folder on the conversion computers is your AFS home folder -- allowing access to your data from any CNF computer with the AFS software installed.

Logging in from CNF Thin

  2. Choose Korat to login to Korat or Minx to login to Minx -- you will not be prompted for your password

Logging in from Windows

For use from the Virtual CAD Rm Service, you must use the Microsoft Remote Desktop client to connect to the Virtual CAD Rm

Problems with Exceed

If, upon starting exceed, you receive an error message about a file, "mgc.fdb", being too large, just delete that file.

You may wish to leave the error message box open so that you can follow the Windows directory structure path down to the mgc.fdb file. However, you will not be able to actually delete the mgc.fdb file until you click "OK" in the error box.

Problems with .Xauthority locking

Local /scratch Disk Space

Both Korat and Minx include a large shared disk space located in the top level /scratch folder. Working directly out of /scratch will provide faster disk access than working out of your networked home folder.

This disk space is shared by all users and is not backed up. 

Create a subfolder with your name under /scratch and work in that subfolder. When done, remember to copy any files you care to keep back to your networked AFS home folder. And then remove any remaining files in /scratch to free up disk space for other users.
