Lab:B209

B209 Fitzpatrick is a computer lab used by EGR 103, EGR 224, ECE 382, ME 131, and occasionally ME 141 and ME 160.

Specifications

• 49 networked Windows 8.1 computers with WIN domain credential logins split up into 24 lab benches
• 1 instructor station Windows 8.1 - equipped with a SMART Sympodium
• Projection system with screen
• WolfVision document camera
• 25 National Instruments NI PCI 6014e or NI PCI 6221 cards (one at instructor station, one per lab bench)
• 20 Circuit Specialists PBB 272 powered breadboards
• 20 Circuit Specialists MS8264 digital multimeters

Using the PCs to Run Unix Programs Remotely

Here is the somewhat long-form of the log-in procedure:

1. Pick a PC
2. Log in using your OIT WIN credentials
3. Start MobaXterm
4. Type

    ssh -XY NETID@teer##.oit.duke.edu
   

   where NETID is your NET ID and ## is the two digit number of the Teer machine you want to use.

5. If you are thinking about printing during this session, type

   lpq
   

   to check the line printer queue - if there are no entries, you are set. If there is a list of files, the particular Teer machine to which you have connected is detached from the ePrint queue. If you are planning to print anything out, you will want to log into a different Teer machine.

Problems Logging In

• If xterm will not work and if the error is something about "error in locking authority file"

  Go to the PuTTY page regarding Xauthority_file_locking

• If x-win needs a license, use the Activation License option and note that the license will be on the screen in the front of the room.
• If your password doesn't work or matlab "doesn't exist,"

  try logging in to a different Teer machine

• If PuTTY claims that you cannot connect to localhost or some other graphical problem:
  1. Make sure the Teer machine did not complain about an error in locking authority file - if it did, see solution above.
  2. Make sure X-Win 32 is running.
  3. Hover over the X-Win icon to make sure it is Display 0 - if not, see the X-Win 32 page for troubleshooting.
  4. Exit PuTTY, restart it, load the session you tried to open, go to X11 or Tunneling in the Category, and make sure X11 was checked
  5. If none of that works, find a TA or the instructor.

Software

Partial list:

Specifically for EGR 103

• Acrobat reader
• ePrint
• MATLAB with toolboxes (esp. Simulink, data acquisition, controls)
  • Be sure shortcut has "Start In" of C:\Documents and Settings\mrglocal\My Documents\MATLAB
• Microsoft Office
• National Instruments Measurements and drivers
• National Instruments LabVIEW (as of Fall 2010)
• PuTTY (including configuration file to log in to any Teer machines with X11 forwarding)
  • Fall 2013: The configuration files do not seem to be static at the moment - hopefully this can be fixed
• SSH (including file transfer)
• X-Win 32

Tech Notes

• After installing a new version of MATLAB 32-bit, be sure to:
  • Right-click and run as administrator
  • daqregister('nidaq')

Other courses
