Getting Started

Download and install the Citrix client for your platform:

  • For a simplified web-only version of the Windows client, install this .msi file http://ter.ps/vclwin and you can then launch applications from the web page without further configuration
  • Windows XP, Vista, 7 and 8 - Choose the Download button for "Citrix Receiver".
    When prompted, enter https://virtlab.eng.umd.edu as the web server, UMD.EDU\your UM directory ID as the domain, and your UM directory password as password.

    Receiver Log on
    Once you set up Receiver Enterprise, you can access VCL applications from the Start menu < Programs < ENGR VCL (you can still launch apps from the webpage as well).

Login

After installing the client, go to Login page and enter your Directory ID in lowercase and your directory password.

Run Application

After logging in, click on an application to run the program. When prompted, choose "Permit all access" to allow the VCL to access your machine for opening and saving files. Check the "Do not ask me again for this site" box to not be asked every time you use the VCL from your computer.

Saving Files

Saving to your personal computer:

  • Save in either \\Client\C$ or V:(location will vary depending on the application you’re using). You cannot save to the C: drive, because it belongs to the server. On Windows, \\Client\C$ or V: is the root directory of your client computer. On a Mac, \\Client\C$ or V: is your Mac Home folder.
    drives
  • Windows users can save files to either the Documents or the Desktop folders on the VCL, as they correspond to the folders on your local machine. Before saving, you should verify that files in Documents or Desktop are indeed pointing to your local system; if not, they will be lost when your session ends.

Saving to VCL Server User Folder (U):

A new option to save to a user folder on a VCL server share. Your folder will be mapped as the (U:) drive.

  • 100MB storage per user, saved files available to you in future sessions
  • Available via Secure FTP, such as WinSCP on Windows or Fetch on a Mac, hostname: vclfs.eng.umd.edu
  • May have better performance with applications that use a lot of disk I/O
  • Alternative if you are having an issue saving locally, or some applications which have issues saving locally such as Cadence

Save to U drive, VCL.Userspace

Saving to TerpConnect:

Some applications will allow you to use your TerpConnect space (1 GB of online space for file storage or website hosting). You can access those applications from the VCL's TerpConnect folder.
terpconnect

After launching one of the applications in the VCL TerpConnect folder, you should see your own TerpConnect account as the T: drive on the VCL for opening and saving files.

Files saved on TerpConnect can be accessed outside of the VCL by either logging into its web interface, or by using secure-FTP software, such as WinSCP on Windows or Fetch on a Mac.

You may also access your Terpconnect space from the T: drive in our physical computer labs.

Saving to USB & External Hard Drives:

On many applications, you will be able to save to other drives on your client machine, such as a USB device or additional hard drive.

Saving to your iPad:

To save files onto your iPad, you will need to turn on Shared Documents.

  • From the iPad Citrix Receiver click the Gear icon in the upper right, choose Advanced, and then turn on Shared Documents.
    iPad
  • Relaunch your session
  • Save locally via the \\Client\C$(V:) just as you would do from a typical VCL session from a PC or Mac.

Note: Files saved from the VCL are not accessible from other iPad apps.

Logging Out

Windows

In most cases, exiting an application will close your session; however, closing some applications (such as ProE, Cadence, and Gambit) don’t always fully your session properly. If you are having trouble running an application you recently closed, your session may not have fully terminated.

To fully end your session:

  1. Right-click on the Citrix icon in the icon tray in lower right-hand corner of the screen.
  2. Select Online Sessions.
  3. Choose Connection Center.
  4. Highlight the server, then Log Off.
    logoff

Mac

  1. Right click on the Citrix Viewer icon in the Dock and choose Quit.
    Quitting Citrix Viewer
  2. Choose Log Off.
    Log Off

Browsers

Internet Explorer 9

You may need to add https://virtlab.eng.umd.edu to your trusted sites list. To do so from the VCL applications page:

  1. Click the gear icon on the far right of IE9.
  2. Click Security tab.
  3. Click Trusted Sites icon.
  4. Click Sites button.
  5. Enter https://virtlab.eng.umd.edu in the “Add this website to the zone:” text box
  6. Choose Add.
  7. Hit Close and OK.

Timeouts

Your VCL session will disconnect if you do not use your keyboard or mouse for over 3 hours.

If network connectivity is lost, sessions will automatically end after 10 minutes.

The web interface will timeout after 30 minutes; however, this timeout will NOT quit your application. You only need to be logged in to the web interface to LAUNCH an application. Once you have launched an application, the VCL session is independent from the web browser session (you could close the browser you used to launch the application and your app will still be running).

Disregard the following messages:
VCLerror

Time out

Application-specific information

Cadence/PSpice: You must use your TerpConnect space (T: drive) on Windows PCs! Trying to open/save file on the \\Client\C$ or V: drive will result in an unrecoverable error. Saving locally on a Mac is fine.
