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:

Updated winterm.eecs now available

by

An updated winterm.eecs, running Windows Server 2025, is now available as a Windows Remote Desktop Server. As soon as the new DNS records propagate, your connection to winterm.eecs will find this updated OS with updated software versions.

Access and software is much like the previous winterm.eecs, though with a desktop experience that’s similar to Windows 11. See our EECS Login Servers page for more information on using winterm.eecs.

If you need to access the previous winterm.eecs (e.g. to copy files kept locally), it will remain online for the next week or two as winterm-old.eecs.berkeley.edu. Feel free to contact help@eecs if you need us to copy your profile from winterm-old to the new winterm.

New DNS Nameserver: themis.eecs

by

System administrators in EECS may be familiar with our DNS nameservers cronus and rhea. We now have a new nameserver, physically located in Cory Hall, named themis. If your systems are typical DHCP clients, or you don’t use the EECS wired network, then you should have nothing to change.

We are planning to replace and retire rhea according to the following schedule:

  • Thu Oct 15 — We will update our DHCP configuration, telling Cory Hall DHCP clients to use themis and cronus, and telling other DHCP clients to use cronus and themis.
  • November/December — We will monitor any continued usage of rhea for DNS, and periodically alert system administrators so they can update their systems to use themis instead.
  • early January — We will retire rhea, but will point its name and IP address at cronus.

Announcing Retirement of the EECS-PSK Wireless Network

by

EECS-PSK Broadcast Ceases May 19th

On Friday, May 19th at 6:30AM, we will cease public broadcast of the EECS-PSK wireless network. The network will continue to exist and devices already configured to use it will be able to continue to do so throughout the Summer semester. However, it will not be available as a visible option to new devices which are not currently configured to connect to EECS-PSK. In other words, EECS-PSK will become a hidden SSID.

We recommend users of EECS-PSK immediately begin transitioning to either eduroam or Berkeley-IoT. eduroam is appropriate for devices such as laptops, desktops, phones and tablets; whereas Berkeley-IoT is appropriate for simpler devices which are not capable of authenticating to eduroam (i.e. devices which cannot perform 802.1X authentication).

Information about how to connect to eduroam and Berkeley-IoT is available at https://technology.berkeley.edu/wi-fi.

Please read the full post below for more information, including the final shutdown date for EECS-PSK. Contact us at help@eecs.berkeley.edu if you have any questions or concerns.

IRIS to begin syncing names from CalNet

by

Currently, when an IRIS account is created, the account name is set by the person requesting the account. It can be changed afterward, but such requests are processed manually.

In order to facilitate compliance with the new Gender Recognition and Lived Name policy, beginning on April 4, IRIS will begin syncing the following fields from the CalNet Directory to our systems:

  • First Name
  • Last Name

These fields are under the direct control of the owner. You can use a form on the CalNet website to update these fields.  We strongly recommend everyone review their current name settings so they are not surprised by any changes. You may have one of those accounts where your last name is in all capital letters – this is where you can change that.

We will sync these fields over from CalNet once a day at about 7am.  The updated fields will appear in these places:

One added benefit of this is that we will begin supporting Unicode characters in these name fields so that we can properly display non-Latin characters.  You can add Unicode characters using the CalNet update form.

Campus Wi-Fi Support for Fall Start

by

As many return to campus for the beginning of Fall Semester, we fully expect to experience some issues with campus Wi-Fi. Campus has made many improvements to our growing Aruba Wi-Fi infrastructure, but increased traffic may reveal additional avenues for improvement. And some people will need assistance with individual devices on Wi-Fi.

Beginning next Monday, August 22, campus is increasing drop-in and phone support for Wi-Fi, for the first few weeks of the semester. Anybody with Wi-Fi issues is encouraged to call or drop-in, for quickest Wi-Fi support. An Instructor Hotline is available, and Hotspots can be requested. Please see the following page for details:

It’s important to troubleshoot any issues on a case-by-case basis, so that service can be improved for everyone.
