CLASSE Windows Laptops: Monday Night Updates

If you are using a CLASSE-managed Windows laptop, please make sure it is on a CLASSE network every Monday night through Tuesday morning to receive weekly updates. You may connect to the CLASSE VPN or an LNS Protected ethernet cable, and please plug in your power cord. Doing so will ensure that your laptop is kept up to date. As usual, these Monday night updates might require multiple reboots of your laptop. More information about connecting laptops to a CLASSE network can be found in our LaptopUsersGuide.

New Windows Printer Queues

As previously announced, all Windows printer queues have now been migrated from CUPS to PrinterLogic. If your CLASSE-managed Windows computer no longer shows any printers available, please reboot twice and wait 30 minutes for the printer list to repopulate. If your printer list remains empty after rebooting, please submit a ServiceRequest to report the problem. The most up-to-date queue names can be found in our printer documentation.

CLASSE Duo: Two-Factor Authentication

In light of the increased threat posed by ransomware and account compromises, CLASSE is adopting the use of Duo two-factor authentication for enhanced security of web services and remote logins. CLASSE Duo operates very similarly to Cornell's Duo service, although a separate CLASSE registration is required. To enroll in CLASSE Duo, please see these instructions for our web-based management portal. CLASSE Duo is currently required for the new VPN (Pritunl), and we plan to enable it for additional services in the future. If you have any questions or concerns about CLASSE Duo, please submit a ServiceRequest.

CULearn and Vivaldi: Enabling Pop-Up Windows

The Vivaldi web browser is compatible with CULearn, even though it is not explicitly listed as a supported browser (Vivaldi and Chrome share the same Chromium codebase). In order to launch CULearn trainings in Vivaldi, please follow these instructions for enabling pop-up windows on the CULearn site. Also, we have received reports of the CULearn server being overloaded with high demand, so if you find that a CULearn training fails to launch, please wait until later in the day and try again.

General network and server maintenance will occur every Tuesday from 12:00 noon to 2:00 PM. The CLASSE-IT group will always announce any expected disruptions in our NewsLetter and via CLASSE-IT-NEWS-L, but with the size and complexity of our network there is always the potential for something to go wrong. We will do our best to contain all network maintenance and planned outages to Tuesdays from 12:00 noon to 2:00 PM.

Unless other arrangements have been made, CLASSE-managed Windows systems may be updated and rebooted on Tuesday morning at 2:00 AM, so please avoid critical or lengthy operations at that time. For more details, please see SystemExpectations.
