Various how-to questions and instructions for IT-related matters.

Request help from IT

Post a ticket to the RT ticket system. Indicate if the issue is urgent or high-priority. Issues that prevent you from doing your work are high-priority. Use a concise subject for the email.

RT will issue you a username and password upon your first ticket. Please log into RT and change your password to one you can easily recall.

You can also create tickets directly in RT if you have received a username and password previously.

In case of an emergency, stop by Jon Auman's office during working hours, or call the IT emergency number 919-668-9105 (89105 from within NESCent) during off-hours. It will ring to the NESCent IT person on call, currently usually Jon Auman.

If you don't need immediate attention to your problem, creating a trouble ticket is the best way of making sure your issue will be tracked, communicated, and resolved, as well as providing us with the ability to allocate our time most effeciently.

Getting set up

Obtain a Duke NetID

The Duke NetID is an electronic alphanumeric identifier that authenticates users to systems and services on the Duke computing network. For example, it is used to authenticate you for using the high-performance compute cluster nodes, and in the future we will also use it for authenticating users to internal applications and web resources. For NESCent fellows, the NetID will usually be associated with an email address <NetID>@duke.edu as well.

Regulary paid fellows will automatically get a NetID assigned once their records are in the Duke system. Contact the OIT Help Desk at 684-2200 if you have not been notified about your NetID but should have.

Duke also can create NetIDs for "anyone formally associated with Duke as long as they are sponsored by a Duke sponsor." Please see Karen Henry if you need to be sponsored, or if you need to sponsor visitors for receiving a NetID. The information needed from each person to be issued a NetID is documented on the OIT helpdesk page for NetIDs. The Duke sponsor needs to email the information for each sponsored person to dukeid@duke.edu. Please allow 1-2 weeks of advance processing time for bulk requests. If the NetIDs are needed for access to the compute cluster, Jon Auman, NESCent's DSCR liaison, needs to transmit the NetIDs to be granted access to the HPC staff. Allow an additional week for this step to complete.

Setup Duke Email

The Duke mail server settings for an email client are:

  • Incomming mail server address: ... imap.duke.edu

Ensure that the connection is set to "SSL." This will change the port number to 993 instead of 143.

  • Outgoing mail server address: ...... smtp.duke.edu

If you are on campus, you should use this address with port number 25
If you are off campus, you have two choices:

  • If you are setting this up on a laptop, use smtp.duke.edu and set the connection to use "SSL"
  • If you are setting this up on a desktop, use your Internet Service Provider's (ISP) outgoing mail server address.

EXAMPLE: If your ISP is Road Runner, the address is smtp-server.nc.rr.com
All ISPs have this address usually posted in their FAQs or help sections.

Get on the NESCent internal mailing list

Sign up with your email address on the subscription page.

Long term science visitors and staff, including students, will be signed up automatically to this mailing list, and also to the postdocs or sabbatical scholars list if appropriate.

For students, please send an email to help@nescent.org once a student leaves so that IT can remove him/her from the internal mailing list.

Install the NESCent shared B/W and color printers

Setup the printers as IP printers:

NESCent Black White printer (HP LaserJet 4250)

IP Address: 152.3.58.89

In Windows:

First download a driver and run the exe. You can download it here:
http://internal.nescent.org/software/printers/HP4250/lj4x50pcl6win2kxp2003.exe

By default. it will unzip the drivers to this location:
c:\HP LaserJet 4x50
You'll need to know this later on.

  1. Start > Settings > Printers and Faxes
  2. Add a Printer
  3. Next
  4. Choose Local printer, uncheck automatically detect plug and play printers if selected.
  5. Select "create a new port" and Type of port : standard tcp/ip port
  6. Next > Next
  7. Printer name or IP address : 152.3.58.89
  8. Next
  9. default of "Standard: generic network card" is fine
  10. Next & Finish
  11. Select Have Disk
  12. Browse to the location where you unzipped the drivers (e.g. 'c:\HP LaserJet 4x50') and hit next
  13. Select the HP LaserJet 4250 PCL6
  14. Printer Name: whatever you want, i call the NESCent HP LJ4250-B&W
  15. Default printer? your choice
  16. Print test page? your choice
  17. Hit Next & Finish if necessary

IN OSX

As long as you are on the WIRED network, you will be able to see the NESCent printers via Bonjour/Rendezvous service. However, this will not work under wireless. Therefore, I recommend setting up the printer as a LPD printer.

  1. Go to System Preferences>Print & Fax
  2. Hit the + sign in the bottom left hand of the screen (to add a printer)
  3. For protocol, choose Line Printer Daemon - LPD
  4. For address, type 152.3.58.89
  5. You can leave queue blank
  6. The name will default to IP address, but i like to make it more meaningful, like "NESCent B&W HP 4250"
  7. Print using : click on HP, then click on HP Laserjet 4250
  8. Click on Add.
  9. In the next screen, click on duplex continue.
  10. Click continue, and you're done.

NESCent Color printer (HP LaserJet 4650)

By default. it will unzip the drivers to this location:
c:\HP color LaserJet 4650
You'll need to know this later on.

Same as above, except use 152.3.58.90 for IP address.
Use HP LaserJet 4650 PCL6 as the model

IN OSX

As long as you are on the WIRED network, you will be able to see the NESCent printers via Bonjour/Rendezvous service. However, this will not work under wireless. Therefore, I recommend setting up the printer as a LPD printer.

  1. Got to System Preferences>Print & Fax
  2. Hit the + sign in the bottom left hand of the screen (to add a printer)
  3. For protocol, choose Line Printer Daemon - LPD
  4. For address, type 152.3.58.90

          Interrupt:7
Use whatever comes after HWaddr. In this case, it is 00:A0:D1:E4:53:22

Wireless access

I usually only register the wireless card for working groups and meetings unless the user cannot use wireless or really need wired for some reason.

  1. Go to http://netreg.duke.edu/ and click on "Enter".
  2. Login with your NetID
  3. Click "Register New Machine"
  4. Under Select the Subnet, Select "TLS Wireless (152.3.149.0/24)"
  5. Next to hostname, give it a name of your choice. I usually do like GMOD1, GMOD2, etc, using a shortname for the visiting working group. If it is a staff member, I usually use their name. The name cannot contain spaces and shouldonly contain alphanumeric characters.
  6. Under hardware address, paste in the users MAC address (aka hardware address) for the wireless card.
  7. Under affiliation, select "National Evolutionary Synthesis Center"
  8. Hit Continue.
  9. You are done, and can now logout.

Please allow about 5 minutes for the connection to become active. You may need to repair the network conneciton on windows, or deactivate and reactivate the airport under OS X.

Wired access

You should not need to do this very often, but here are the insturctions anyways.

  1. Go to http://netreg.duke.edu/ and click on "Enter".
  2. Login with your NetID
  3. Click "Register New Machine"
  4. Under Select the Building, Select "Erwin Square Mill"
  5. Next to hostname, give it a name of your choice. I usually do like GMOD1, GMOD2, etc, using a shortname for the visiting working group. If it is a staff member, I usually use their name. The name cannot contain spaces and shouldonly contain alphanumeric characters. Also, you may have a choice of which domain to use. First choice is aas.duke.edu, if not available, then bootp.duke.edu.
  6. Under hardware address, paste in the users MAC address (aka hardware address) for the wired network card.
  7. Under affiliation, select "National Evolutionary Synthesis Center"
  8. Hit Continue.
  9. You are done, and can now logout.

Polycom

Use the audio PolyCom for teleconferencing

  • Phone number is 919-668-4568

Setup

The polycom has got two peices. One piece has the phone line, and connects to the wall. This is the smaller piece. The other piece is the voicepiece that looks like a triangle.

Connect the phone cord of the smaller piece into the analog wall jack. In conference rooms #1 & #2, this jack is under the table. In #3, it is near the window. Plugin the powercord.

Plugin the triangle unit. It will find the wall unit and once connected you should be able to get a dial tone.

Usage

  • Making a call
To connect to just one party, press the large button on the left hand side with the icon of a phone receiver. Dial the phone number with area code. You do not need to dial 9, but you will need an access code to dial long distance (oustide the 919 area code).
  • Making Conference calls
You may conference with two parties. Our setup does not allow more than that. To add a second party:
  1. While on an active call, press the Conference button . The first call is automatically placed on hold.
  2. Dial the number you wish to call. You may use the Redial or Direct Dial method.
  3. Press the Conference button or JOIN soft key to join the second call. To drop the second call, press the Conf key again.
-OR-
  1. Press the HOLD soft key to place the first call on hold.
  2. Press the Conference button and enter the number you wish to call. You may use the Redial or Direct Dial method.
  • Receiving a call: To receive an incoming call, just hit the phone button.
  • Answering a Second Call: If you are on a call when another call is received, you will hear a Call Waiting tone.
    • Press the Conference button (picture of a bunch of people, just under the phone button) to answer the incoming call. This first call will be automatically placed on hold.
    • Switch back and forth between calls using the conference button.

Consult the the full user manual for further details.

Use the PolyCom for a videoconference with collaborators outside the center

Setup

Setup the videoconferencing cart where you want. Make sure you are close enough to a network jack in order to connect the polycom unit. Plug in the master power cable in the back. Plug in the network cable.

Turn on the monitors with the silver remote control. You can each individual monitor by stepping close to that indiviual monitor and aiming directly at it, otherwise the remote will control both. By default the left hand side will show the remote connection, and the right hand side will show your local camera, or your laptop if connected and setup correctly (to be discussed later).

To turn off the machine, disconnect all calls, turn off the monitors, and unplug the machine.

Dial a call

Use the black remote. Simply enter the IP address or IP name in the dialing field, and press the green call button at the upper left hand corner.

Sympodium

The following directions where taken from the "Sympodium ID370 Interactive Pen Display Installation Guide" which can be downloaded here Media:Sympodium ID370 Interactive Pen Display Installation Guide.pdf

Software Installation

  • If you haven’t done so already, turn on the computer and the interactive pen display.
  • Close all open applications on the computer.
  • Insert the SMART Board software CD into the CD drive.
For most systems, the CD is self-starting. If the CD doesn’t start automatically: (Windows operating systems) select Start > Run, and enter x:\autorun.exe (where x: is your CD drive).
(Mac computers) open your CD drive, and double-click the install file.
  • Follow the on-screen instructions.
NOTE: You’ll have to use the connected keyboard and mouse, because the pen doesn’t work until the SMART Board tools are running. If SMART Board software doesn’t recognize the interactive pen display, you may have to activate the port manually using an attached keyboard or mouse. For further information, read the SMART Board software online Help. Also, if the interactive pen display is your secondary monitor, you may need to enable it in your Display Properties Control Panel.
