Scheduled Maintenance for Wireless Authentication Server

by

On Wednesday, November 5 at 1PM, we will be performing scheduled maintenance on the primary wireless authentication (aka RADIUS) server, etips1.eecs. The maintenance window is scheduled to end at 2PM.

EECS-Secure will not be affected during the maintenance, as the secondary server will be available to process authentication requests. However, the secondary server is currently unable to process requests for EECS-Guest, and as a result EECS-Guest will NOT be accepting new connections. Existing sessions should not be disconnected, but any new EECS-Guest sessions will fail to authenticate during the maintenance. We recommend that visitors use CalVisitor as a workaround during this time.

Please direct any questions, comments, or concerns to help@eecs.berkeley.edu.

eduroam now available in EECS

by

The eduroam wireless network is now available in EECS. eduroam is a worldwide wireless network which is shared across many participating institutions. Visitors from other institutions will be able to log on to eduroam while at Berkeley, and anyone from Berkeley who is visiting another institution can log into eduroam using their AirBears 2 key.

For more details on eduroam, please see Berkeley IST���s eduroam information page at http://ist.berkeley.edu/airbears#eduroam or the eduroam website at eduroam.org.

For a general overview of campus-provided wireless offerings (not including EECS networks), please see https://kb.berkeley.edu/page.php?id=27815

If you have any questions, concerns, or issues with eduroam, please send a message to help@eecs.berkeley.edu.

Thanks,

CalVisitor Wireless Now Available in EECS

by

The CalVisitor guest wireless network is now available in EECS.

UC Berkeley Students, Faculty, and Staff are strongly encouraged to continue to use AirBears2 or the IRIS wireless
networks instead of the CalVisitor guest wireless network.

CalVisitor does not use authentication or encryption and does not require host registration. CalVisitor provides access to all websites via HTTP and HTTPS (ports 80/443) and to most common VPN services. However, other services may not function. CalVisitor provides users with access to registered websites on the IRIS networks.

For more details on the CalVisitor service, please see Berkeley IST’s CalVisitor information page at https://ist.berkeley.edu/airbears/calvisitor

For a general overview of campus-provided wireless offerings (not including EECS networks), please see https://kb.berkeley.edu/page.php?id=27815

If you have any questions, concerns, or issues with CalVisitor, please send a message to help@eecs.berkeley.edu.

Thanks,

EECS/IRIS Network Group

P.S. For those who are curious, we expect to roll out eduroam within the next couple of weeks.

Unscheduled Wireless Outage, HMMB and Sibley Auditorium

by

We are currently experiencing an unscheduled wireless outage in some locations in the Hearst Memorial Mining Building, as well as in the Sibley Auditorium in the Bechtel Engineering Center. The outage is due to a campus zone router crash, and many campus-managed wired and wireless networks are also affected.

IST/Telecom is working to restore service and we will update this news item when service has been restored. We apologize for any issues caused by this interruption.

apps.eecs, wiki.eecs downtime Friday 8am

by

The server hosting apps.eecs.berkeley,edu, wik.eecs.berkeley.edu and some other project websites[*] will be rebooted Friday, October 17th 2014 between 8am and 9am. Total downtime should be around 5 to 10 minutes.

This server is experiencing poor network performance. This reboot will be to reconfigure the virtual machine with a new network driver which has shown significantly better performance in our testing. Current bandwith to our NFS server is lmited to around 1.2 MB/s. In testing with the new driver, we are getting around 25 MB/s.

As usual, please send any questions or comments to the IRIS helpdesk at help@eecs.berkeley.edu.

[*] The full list of affected websites is:

  • bjc.berkeley.edu
  • bsim.eecs.berkeley.edu
  • csillustrated.berkeley.edu
  • leed.eecs.berkeley.edu
  • rt.eecs.berkeley.edu
  • snap.berkeley.edu
  • wiki.eecs.berkeley.edu
  • www-device.eecs.berkeley.edu
  • www-video.eecs.berkeley.edu
