Usage of lnx201

Over the past year, we have been promoting lnx201.classe.cornell.edu as a general purpose Linux login node, to be used in conjunction with the Linux compute farm (https://wiki.classe.cornell.edu/Computing/GridEngine). Given the recent spike in usage of lnx201, we would like to remind everyone of some basic usage guidelines: Thank you for your cooperation. We would appreciate any suggestions for improvements to our computing infrastructure.

Upcoming network maintenance

Please be aware that during the summer down, there will be occasional and brief network interruptions of one minute or less as we update network configurations around the lab. Each interruption will be announced beforehand. Please do not hesitate to contact the IT group at service-classe@cornell.edu with any questions or concerns.

RedRover-Secure retiring tomorrow

On July 15 (tomorrow!), CIT will discontinue the RedRover-Secure wireless service. For more information, see http://itnews.cornell.edu/help-itcornell-get-message-out-redrover-secure-retiring-july-15.

For secure wireless service, please use eduroam instead: http://www.it.cornell.edu/services/wifi/. Eduroam is a global service that can also be used at other participating institutions.

Regular RedRover (not secure) will remain in place.

TeX Live 2014 distribution is available to all CLASSE SL6 Linux systems. Please see the LaTeX wiki page for details and instructions on use.

The HyperNews email distribution list (acc-code-lepp@lnx122.lns.cornell.edu) will no longer receive the Accelerator Libraries Rotation notifications - all notifications will now be sent to the CLASSE-ACC-COMP-L listserv email list. If you are not subscribed the CLASSE-ACC-COMP-L and wish to join, please send an email message to:

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.
