Virtual Machine Cluster Maintenance: Wednesday, 22-Sep-2021 @ 10:30 AM

On Wednesday, 22-Sep-2021, between 10:30 AM and 12:00 noon, we will perform routine testing and maintenance of the CLASSE Virtual Machine (VM) cluster. The CLASSE VM cluster provides many central services, such as printing, networked licenses, AppsAnywhere, ScreenConnect, and WinAPP2. We do not anticipate any service interruptions, but any VM reboots will be announced on the CLASSE-IT-NEWS-L mailing list.

ScreenConnect Update: Tuesday, 28-Sep-2021 @ 10:30 AM

On Tuesday, 28-Sep-2021, starting at 10:30 AM, the ScreenConnect service will be unavailable for up to an hour for a server update. During this time, you will be disconnected from existing remote sessions, and you will not be able to start new remote sessions. We will distribute client updates during the next standard maintenance window.

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.

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.
