Respondus LockDown Browser

Respondus LockDown Browser is a piece of proprietary online testing software developed by Respondus, Inc, and used by departments, including the Department of Engineering Education. Success in running under Wine varies from version to version, and may involve complex installation procedures, and the software actively prevents itself from running in a virtual machine.

Official Description

From the Product page:

LockDown Browser® is a custom browser that locks down the testing environment within Blackboard, ANGEL, Brightspace by D2L, Canvas, Moodle, and Sakai. When students use LockDown Browser they are unable to print, copy, go to another URL, or access other applications.

Malware

LockDown requires administrative privileges to run, and cannot be run as an unprivileged user. Features of the browser could be construed to violate Virginia Tech Acceptable Use Policy by engag[ing] in any activity that might be purposefully harmful to systems or to any information stored thereon..., however its use is not widespread enough for this to gain any note.

Running the Software

Wine

There are multiple tutorials available by a quick web search which claim to get this working in Wine, however, to date, no member of VTLUUG has succeeded in doing so and existing information indicates it varies by version of the browser.

Virtual Machine (KVM)

This refuses to run in a Virtual Machine. It may be possible to add the -cpu kvm=off flag to Qemu to prevent it from detecting a virtualized environment, but this has not been tested to date. It may also be necessary to disable Virtio drivers and devices.

Natively (Windows or OS X)

To run on Windows, the software requires administrative privileges. Previous versions were shown to have used Internet Explorer with certain modifications executed on the fly, to add the "Lock Down" features, however it currently appears to be a stand-alone browser with some resemblance to Google's Chrome.

On Mac OS X, it requires that The Safari browser must be configured to the minimum requirements for the Learning Management System being used, indicating that it piggybacks off of Safari features, although it is unknown if it requires administrative privileges on Mac OS X.

A version for iOS (iPad-only) is also available.
