CLASSE Duo for CHESS Remote Logins: Tuesday, 11-Jan-2022 @ 10:00 AM

As previously announced, CLASSE has adopted Duo for two-factor authentication, and we are gradually phasing in its use with CLASSE web services and remote logins. As the next step in this process, on Tuesday, 11-Jan-2022 at 10:00 AM, CLASSE Duo will be enabled for remote access to the CHESS station computers via NoMachine, SSH, and X2Go. If you have not done so already, please enroll in CLASSE Duo using our web-based management portal. CLASSE Duo operates very similarly to Cornell's Duo service, although a separate CLASSE registration is required. If you have any questions or concerns about CLASSE Duo, please submit a ServiceRequest.

[PSA] CIT Network Interruption: Sunday, 16-Jan-2022 @ 5:00 AM

On Sunday, 16-Jan-2022, between 5:00 AM and 10:00 AM, CIT Network Engineering will upgrade and reboot all Ithaca campus routers. Both wired and wireless network connectivity will be disrupted for approximately 10–15 minutes during this window. For CLASSE personnel, the main impact will be on off-campus connectivity and RedRover/eduroam wireless. For more information, please see https://itservicealerts.hosting.cornell.edu/view/6542.

OpenVPN Retirement: Monday, 28-Feb-2022

On Monday, 28-Feb-2022, we plan to shut down the legacy CLASSE VPN service, OpenVPN. At this point, CLASSE personnel should begin to use our new VPN, known as Pritunl. Instructions for using Pritunl from CLASSE-managed and personal computers are available at ClasseVPN. For enhanced security, our Pritunl deployment includes two-factor authentication via CLASSE Duo.

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.
