Computer network and telephone upgrades in June and July, 2011
During June and July, 2011, the computer network in Geology Corner, Mitchell Earth Sciences, and Green Earth Sciences buildings will be upgraded to provide gigabit (1,000 megabits/second) speed to all computers (ten times our current standard), and support new Voice-over-IP (VoIP) network telephones with advanced features that will replace all our old analog phones. Only selected network jacks will be activated for gigabit service as described in the article; all others will be de-activated. The Y2E2 building already has gigabit network service with VoIP phones, so it will not be upgraded.

Exception: Desktop and Documents folder files for users who don't have a home share, including most undergraduates and visitors, will be erased because they are stored on the local hard drive.

July 30, 2010

Door codes changed for Mitchell computer labs
The combination codes needed to open the doors to the School of Earth Sciences computer labs have been changed. This is done periodically as a security measure and to limit use of the labs to authorized people. Anyone in the School of Earth Sciences may request the new codes.

July 1, 2010

Power management to be implemented on supported computers
As part of the university's sustainability intiatives, power management features will be centrally enabled on CRC supported computers in Earth Sciences using the BigFix program on July 14, 2010. The basic setting for all School computers will be to put the monitor to sleep after 15 minutes of inactivity. Office computers (but not lab computers) will be targeted for more aggressive energy savings by putting the entire computer to sleep after 30 minutes of inactivity. Users can switch between the two settings or "opt out".

OS upgrade on Sesfs improves compatibility with Mac OS X 10.5
The March 31 operating system upgrade of the School of Earth Sciences file server, sesfs.stanford.edu, fixed problems of compatibility among files created by different versions of Mac OS X, and problems saving files from Mac OS X 10.5 connections. An essential part of this fix is the presence of the special file com.apple.smb.streams.off file at the top level of every file share. Do not remove this file, or you will create problems for Mac OS X 10.5 connections.

Earth Sciences network firewall tightened on June 25, 2007
A final change to the Earth Sciences network firewall rules at 9:00 a.m. on June 25, 2007, blocks all incoming connections to random TCP ports. Only the connections listed in the Earth Sciences firewall ruleset will be allowed. This change will increase security, but may block many peer-to-peer file sharing programs.

June 7, 2007

Improved anonymous ftp service on pangea
"Anonymous ftp" is a method for allowing anyone on the Internet to access files in a special directory on pangea's disks. It can be used to distribute files to colleagues or collect files from them. This service has been recently improved so it can be used without any special setup.

May 18, 2007

Computer network firewall coming on May 30!
A "firewall" will be enabled on May 30 to protect the Earth Sciences computer network from hacker probes of insecure services and self-propagating virus and worm attacks. Incoming connections will be filtered; outgoing connections will not. Average computer users will see no change; power users and research groups may find some services on their Earth Sciences computers are now blocked.
