Virtual Computer Lab

The Engineering Virtual Computer Lab is a way for you to gain access to most of the Engineering lab's software from a remote location. By using this tool you will be able to do homework or projects from your home or dorm room.

The Virtual Computer Lab uses a program called "Citrix" to connect to the Engineering network. Read these instructions to connnect. Click on the question mark near the Virtual Lab login form for additional help.

Follow this link to access the Virtual Lab. The link will open in a new browser window.

Supported Web Browsers

We recommend using Firefox, Opera, or Internet Explorer. These browsers will recognize the Citrix client and load the published application correctly.

Chrome and Safari may work, but are not ideal. These browsers start the published application using the Java plugin. One of the problems with the Java plugin is that it does not correctly utilize Ctirix load balancing or recognize which computers are currently in the "farm" (i.e., the pool of computers available for this resource). At times the Java plugin connects to computers in the farm and then at other times it tries to connect to servers that are not in the farm.

Policies

Please read this section carefully! You may be denied access to the Virtual Lab if you fail to abide by these policies.

  1. This resource is for academic teaching purposes only. Do not use this resource for any non-academic or commercial purposes.
  2. You may not use this resource outside of the United States.
  3. Due to the scarcity of session licenses, any Virtual Lab session that is idle for over 24 hours will be automatically logged off so that others can use this resource.
  4. Engineering students have access to the Virtual Lab. By default, faculty and staff do not. Faculty and staff may pay an annual fee to access the Virtual Lab for course-related purposes; please contact ENS for details.
  5. Please do not consider the Virtual Lab a purely distance education tool, or a substitute for the physical computer labs. The Virtual Lab is meant to be used as a convenient supplement to the physical computer labs. It is a student-funded project and thus only students have access.
  6. Specifically for ANSYS software products, you may not use the software installed on the Virtual Lab outside of a 50-mile radius of the Fort Collins CSU campus.

Many of the restrictions above are based upon licensing restrictions from the software companies, which we must agree to in order to use their software.

Tips & Troubleshooting

Make sure you have the latest Citrix Receiver installed.
We recommend you uninstall existing versions of the Citrix Receiver that are on your computer, then install the latest Citrix Receiver from the Citrix web site.
You receive the following error message: "You already have an instance of this application open and are not allowed to run more than one instance. Please contact your System Administrator."
Your old session may not have disconnected properly. You can perform the following procedure to fix it yourself:
  1. Log into the Virtual Lab web interface using the link above.
  2. Use the Disconnect link on the grey toolbar on the upper right-hand side of the page.
  3. This will disconnect your session on the server and log you out of the web interface.
  4. Log back in to the web interface. At this point you can restart your session.
  5. If this method does not work, please contact ENS.
I can't find Xming (or similar X-forwarding tool) to log in to the Linux servers.
This is intentional. It is an inefficient use of resources (yours and ours) to use the Virtual Lab to connect to another remote resource. Instead, we recommend that you use Remote Desktop to connect to the Linux servers directly.
The Virtual Lab window is too small.
Mac OS: Follow this procedure to resize the window: Access the Virtual Lab. Select the 'Preferences' tab, then select the 'Session Settings' option. Change 'Window size' to your desired size. Click Save, then log on to the Virtual Lab as usual.
