LNX201 Reboot: Tuesday, 11-Jun-2024 @ 10:30 AM

On Tuesday, 11-Jun-2024 at 10:30 AM, the general Linux login node, LNX201, will be unavailable for approximately 20 minutes while it is rebooted. Please log out of your LNX201 sessions before the scheduled reboot.

Scientific Linux 7 Deprecation

In preparation for the end of support for Scientific Linux 7 (SL7) on 30-Jun-2024, we will be upgrading all CLASSE Linux systems to AlmaLinux 9 over the next few weeks. If you have a CLASSE-managed Linux desktop or laptop system, we will contact you via a ticket to schedule the upgrade. Please also consider switching from lnx201.classe.cornell.edu (SL7) to lnx209.classe.cornell.edu (AlmaLinux 9) as a general-purpose landing pad.

Microsoft Teams

Microsoft is deploying a new version of Teams. You may see a notification banner to switch to the new Teams in Classic Teams. Although you can ignore the banner and there is nothing you need to do now, this is a real notice. Sometime in the indefinite future, Microsoft will disable Classic Teams. When this happens, you will need to use Vivaldi to access teams on CLASSE-managed Windows and Linux computers (teams.microsoft.com).

Beware of Targeted Phishing

In the past month, we have seen an increase in phishing scams directed at CLASSE personnel. Often, these fraudulent emails or texts are sent by someone impersonating a colleague or supervisor, and they usually include an urgent request ("Are you available?"). Before responding to such messages, please check that the sender's email address or phone number is one that you recognize. For more information, please refer to these resources from the Cornell IT Security Office:

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.
