EECS Border Firewall Changes, Mon. March 23

by

On Monday, March 23rd, we will be adding some new ports to the list of ports that are blocked by the EECS border firewall.

For detailed information about the changes, please see our EECS Firewall Ports page (this page requires login). The list of ports that we will add to the block list is at the bottom of that page.

Update 3/23 8:05AM: These changes have taken effect, and the new ports are now being blocked from off-campus. Please contact us at help@eecs.berkeley.edu if you have any questions or notice any issues.

Wireless Networks Offline, Monday 1/5

by

As of about 11:51 AM: wireless networks are offline due to a power issue in one of the campus network core sites. Wired networks are unaffected and continue to operate normally. We will update again when we have more information about the status of the campus network core.

Update 13:36: Campus has begun restoring power to the network core using temporary connections, so we expect to see some wi-fi service resume. However, wi-fi may experience some continuing instability as the work to restore full power goes on.

Update 17:02: Power has been restored and network services should be fully available. There may be some late-night wi-fi disruptions as staff perform some cleanup work.

Please contact us at help@eecs.berkeley.edu if you have any questions.

IT Support During Winter 2025 Energy Curtailment

by

Due to the Winter Holiday, Energy Curtailment, and New Year’s Holidays, the Berkeley campus is officially closed for the period Wednesday, December 24 to Thursday, January 1, reopening on Friday, January 2, 2026. Additionally, much of campus is on reduced support for December 22-23, January 2, and the week of January 5-9.

All departmental computing servers will remain on and should be available during the break, but there will be no staff on site to provide any computing support or handle any requests. Automatic monitoring systems will alert staff to critical infrastructure problems, and any such problems will be dealt with on a best-effort basis.

The IRIS Helpdesk office will be closed Monday, December 22 through Friday, January 2, re-opening fully on Monday, January 12. If you need assistance during the week of January 5-9, please email help@eecs, and we should be able to reply and schedule an appointment with you if needed. Problem reports can be left on the Helpdesk voice mail (510-642-7777) or emailed to help@eecs during the campus closure period, but staff may not receive or reply to these messages until at least January 5.

Requests for network support or new IRIS accounts that are received after noon Thursday, December 18 may not be processed until January 5, 2026.

During the break, Instructional labs will be locked, but the main servers will remain online (for details, see the Instructional website). Instructional support staff will occasionally monitor inst@eecs email over the break. Please be aware, though, that staff may not be able to respond or reply to messages until at least January 5.

Computing support staff will be monitoring their email when possible, so please use standard email addresses to report any urgent problems. As a reminder:

Instructional Computing Environment: inst@eecs

Research / Staff Computing Environment: help@eecs

Happy Holidays!

Corrected exports for EECS NetApp file server

by

A recent report of a discrepancy in our file server NFS exports helped us to discover an error in our NFS export policies. The error would allow shares with the default NFS export setting to be mounted on some systems within EECS networks that they were not intended to be exported to.

We have corrected the error, and audited our NFS export policies. If you discover any unexpected change to availability of your home directory or project space, please feel free to reach out to help@eecs.
