Network interruption at EECS border

by

A little after 1pm today, we experienced a loss of network traffic at the EECS border. Typical network use within EECS continued to work, though it appeared we were cut off from the rest of campus, and the outside world.

Staff investigation found the problem to be at or with one of the department border firewall devices. The secondary firewall device has been made primary now, and traffic is routing properly. Staff will further examine the problem firewall device, to narrow down the specific cause.

Adobe CC 2017 now available on SWW

by

Installer files for campus site-licensed versions of Adobe Creative Cloud 2017 are now available on both WinSWW and MacSWW. This includes separate installers for Adobe Acrobat, Photoshop, and others. Note that access to WinSWW and MacSWW is restricted to those who have Standard IRIS accounts (Limited IRIS accounts do not have access).

These installers are intended for use on university-owned machines that are not managed by Campus Shared Services. For personally-owned machines and further information about Adobe and Microsoft licensing on campus, please visit the campus Software Central website.

Moving wins1.eecs, March 27 9pm

by

Windows Internet Name Service (WINS) is used for name resolution, typically by Microsoft clients, to map hostnames to IP addresses. It allows clients to find machines by name even if they don’t have fixed IP addresses in DNS. In EECS, we have two WINS servers for redundancy, wins1.eecs.berkeley.edu and wins2.eecs.berkeley.edu.

On Monday night at 9pm, in an effort to simplify network routing architecture, we will be replacing the current wins1.eecs with a machine in Cory Hall. Service from wins1.eecs may be unavailable for about an hour.

Because of WINS redundancy, most clients should not notice the downtime.

WINS is a relatively old Microsoft service, and in the coming year we will be examining WINS usage to see if we can plan for retirement of WINS in EECS.

Disable SMBv1 on Windows systems

by

Due to critical vulnerabilities in Windows SMB (file sharing) services, the
campus Information Security & Policy (ISP) group advises
disabling of SMBv1 on all campus Windows systems, and that you prepare to update
all Windows systems quickly on Patch Tuesday (Feb 14) to patch more
recent versions of SMB (SMBv2 and SMBv3).

IT Support During Winter 2016 Energy Curtailment

by

Due to the Winter Holiday, Energy Curtailment, and New Year’s Holidays, the Berkeley campus is officially closed for the period Monday, December 26 to Monday, January 2nd, reopening on Tuesday, January 3, 2017.

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. IRIS staff will be taking advantage of the holiday to do maintenance on some systems which will result in scattered outages, but any such downtime will be separately announced and posted on the IRIS website.

The IRIS Helpdesk will close early at noon on Friday December 23, and will reopen on Tuesday January 3. Problem reports can be left on the Helpdesk voice mail (510-642-7777) or emailed to help@eecs, but staff may not receive or reply to these messages until January 3.

Requests for new IRIS accounts that are received after 5pm December 21 will be processed on January 3, 2017.

During the break, Instructional labs will be locked, but the main servers will remain online (for details, see [the Instructional website](http://inst.eecs.berkeley.edu/End-of-Semester)). Instructional support staff will occasionally monitor inst@eecs email over the break. If you are unable to contact inst@eecs, you can leave a message at 510-643-6141. Please be aware, though, that staff may not be able to respond or reply to messages until January 3.

We recommend that all desktop computers be shutdown during the Energy Curtailment Period. If your Windows computer needs to stay on during the break, we recommend that you check with your system administrator to ensure that Automatic Updates are enabled with the option ???Automatically download the updates and install them on the schedule that I specify??? with a daily update schedule.

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
