Read the newsletter!

Nearly every week, the CLASSE Computer Group publishes a newsletter for the CLASSE user community; a pdf is emailed to everyone in the lab, and copies are also posted in public locations (bulletin boards in elevators and other public locations). Please take the time to read each newsletter, as you will be affected by the items it contains.

Where to go for support

  1. CLASSE Computer Group (CCG)
  2. Cornell Information Technology (CIT)
    • Services/Support for: Red Rover wireless networks, Exchange email, Cornell Box, Kronos, Workday, and others; see http://www.it.cornell.edu/services/ for a complete list
    • Services centrally provided by CIT are supported by CIT. See https://www.it.cornell.edu/support/ to get started getting support for centrally provided services.
    • The CLASSE Computer Group can provide minimal ("best effort") assistance in dealing with CIT.
  3. For other (personal, e.g.) computer support, various OutsideSupport providers may be able to help.

File Storage

  1. files for your personal work-related use
    • Windows: \\samba\user\userid (replace userid with your CLASSE userid)
    • UNIX: /nfs/user/userid
  2. large files or files that other members of your work group will need should be stored in project or group file systems. Please see DataStewardship for more information.
  3. temporary (easily regenerated) files
    • Windows: \\samba\tem, \\samba\tem2, or C:\TEMP
    • UNIX: /cdat/tem, /cdat/tem2, /tmp, or /var/tmp
Important Notes
  • Files in 1. above are backed up. Please see BackupSchedule for a complete list of backed-up file systems.
  • NEVER store important files on a local disk - files on disks physically connected to your computer are NOT BACKED UP.
  • Files stored in C:\TEMP, /tmp, /var/tmp, /cdat/tem or /cdat/tem2 will be deleted if free space on those volumes goes below a preset threshold. Please see TemDisk for more information
For more information on where to store files, please see https://wiki.classe.cornell.edu/Computing/DataStewardship.

Simulation and development applications (multi-platform apps such as: Matlab, Mathematica, Python, etc)

It is likely that the app you want to use is already available in our standard Linux install. Please see LinuxSupport for an introduction to Linux Support at CLASSE.

To use a Linux application, log into a Linux computer
  • directly using the local login window
  • from a Mac: open Terminal, type ssh -Y userid@lnx201.classe.cornell.edu, enter your password when requested
    • Note: X11 or XQuartz required
  • from a Windows PC: double-click on "RunXming" (located on your desktop)
    • put lnx201.classe.cornell.edu in the "Host" box (and press the "Save" button if lnx201 is not in the list of saved hosts)
    • supply user credentials when requested
    • Please see ConnectingToALinuxMachineFromWindows for more information.
Once you are logged in, at the command line prompt type /path_to_app/appname

Windows Apps from Linux or MacOS (Excel, Outlook, Project, etc)

Similarly, Windows applications can be accessed from desktop Linux and Macintosh computers

Printer Locations

The CLASSE Printer List has a table of CLASSE printers along with their locations and other parameters. Please print only what you need to and where you need to - we recycle many printouts sent to the "wrong" printer.

CLASSE Credentials

Please see UserAccountsAndPasswords.
