CLASSE Windows License Server outage (PC176) Tuesday at 10AM

We will be migrating the CLASSE Windows License server (PC176) to winlm.classe.cornell.edu on our HA cluster starting at 10AM. We expect the license server to be back up and running by 11AM. The actual expected outage is likely to be < 5 minutes, but if there are issues could take a little longer. Users should see no impact after the outage, the existing naming continues to work.

Use your CLASSE userid and password for VPN with RedRover

RedRover wireless access will replace "LNS Protected" wireless access in Newman Lab on Wednesday, May 15. If you need to print on Lab printers or access Inventor's Vault while connected to the RedRover wireless network, you'll have to connect to the CLASSE VPN. Many people already make use of the CLASSE VPN when they work from home or elsewhere outside the Lab. Information about the CLASSE VPN is available at https://wiki.lepp.cornell.edu/lepp/bin/view/Computing/Private/OpenVPN

Wired access to the "LNS Protected" network will not be going away. There is no need to use the VPN if your laptop computer is connected to the wired "LNS Protected" network. With Windows 7, it is important to make sure you go into network and sharing center, change adapter settings, and right click and disable the wireless network to actually connect to the wired "LNS Protected" network. Just plugging in a cable will not cause this change. If you have a CLASSE laptop and need to use the wired "LNS Protected" network instead of wireless RedRover and currently do not have wired access, please contact the CLASSE computer group immediately by sending email to service-classe@cornell.edu

Note: All students get charged for their use of off-campus bandwidth (aka NUBB charges), so Lab-supplied devices should be registered for RedRover by staff or faculty.

Newman Telephones

Most of the telephones in Newman Lab were replaced by Voice Over IP (VOIP) sets this past week. If you have any issues with your new telephones or telephone service in general, ask for help from the IT Service Desk by phone at (607) 255-5500, by e-mail at itservicedesk@cornell.edu, or by stopping into the IT Service Desk at 119 CCC.
Please also send email to service-classe@cornell.edu if there is any need for the Computer Group to get involved in resolving the issue.

The instruction booklet for your new IP phones:

This will describe features specific to your new set type and in addition to the telephone system features.

CLASSE Printing

As we proceed with the migration to a unified CLASSE computing facility, we will be standardizing our management of and support for CLASSE printers. Moving forward, all managed CLASSE computers will automatically be given access to all CLASSE printers via the CUPS print server. Rather than requiring individual users to install their own printers and drivers, we have chosen this centralized model based on our experience with LEPP printers. Adopting the CUPS print server at LEPP has significantly reduced the lab's support costs, and it enhances collaboration between our numerous buildings and groups. Users on CLASSE managed computers have the ability to set their default preferred printer, and when needed they have the ability to print to any other printer in the lab.

In the next week, we will begin adding what have historically been CHESS printers to the list of printers available on all managed CLASSE computers. Detailed documentation on printing at CLASSE can be found at https://wiki.lepp.cornell.edu/lepp/bin/view/Computing/PrintingAtCLASSE.



General network and server maintenance will occur every Tuesday from 12 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 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.
