Scientific Linux 5.7

As announced last week, all LEPP SL5 systems have been upgraded to SL5.7. Please note that this update included a new kernel and graphics driver. If you have not already, please reboot your computer at your convenience to start using the new kernel and driver. If you would like help rebooting any computers, please submit a Service Request: either send email to service-lepp@cornell.edu or fill out the Request form at https://wiki.lepp.cornell.edu/lepp/bin/view/Computing/ServiceRequest

For the SL5.7 release notes and additional information on this update, please see http://www.scientificlinux.org/distributions/5x/57/ .

CESR Control System

Maintenance is scheduled for CESR Linux systems from 10am to 12pm on Tuesday, October 4. Any processes running on the new CESR Linux cluster at 10am Tuesday may be killed. In addition, periodic delays may be seen accessing the CESR Online filesystem and CESR Control Account Home Directories during this maintenance.

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.
