  • Connection type/encryption: TLS
  • Username: your Math username
  • Password: for the username above
  • Outgoing/SMTP server:, port: 587, protocol: STARTTLS; authenticate with Math username and password

Backing up Your Files

Ask Laurie Johnson in 102B about backing up your Mac or Windows.

Making X Connections to Linux Machines

We recommend using Cygwin/X. Cygwin installer can be downloaded from After installation is complete, run Cygwin Terminal and then start X by giving a startxwin command. Wait for the (green) “X Applications” icon to appear on your Windows taskbar. The icon gives access to Cygwin/X apps and settings. If the application you are seeking is not listed, you still might be able to run it by first starting XTerm and the running your app from there by typing its name. To run an X application on a remote Linux machine, e.g. gauss, while in XTerm type:
    ssh -X username@gauss program_name


If you really want to view PostScript files on Windows, then you will have to install Ghostscript and Ghostview. The main site is here.



  1. Download “Current Stable Release” from
  2. Start the installer and click through usual “Next >” prompts. Here are the important ones:
    • Choose install type: Join an existing HTCondor pool.
    • Hostname of Central Manager:
    • Submit jobs to HTCondor pool: check.
    • Hosts with Read access: *
    • Hosts with Write access: *
    • Hosts with Administrator access: $(FULL_HOSTNAME).
  3. Restart Windows. HTCondor service should start automatically. Installer should have also added several exceptions to Windows firewall (service names starting with “condor_”).
    N.B.: HTCondor can be started/stopped from the Command Prompt by, for example, “net start condor”. For some reason stopping/restarting fails when attempted from Control Panel - Administration Tools.
  4. Check whether Math HTCondor pool is accessible (Command Prompt):
    Response should be similar to this:
