cronus.cs remains down after neighborhood power outage

by

A power outage to Soda Hall which began around 12:30pm on June 21, 2017 took out many IRIS services.

At about 3:00pm, power was restored to Soda Hall and staff are bringing up network equipment now. The power conditioner in the main Soda machine room had problems recovering, and campus electricians required additional time to get it back online. Our IRIS staff then were able to begin bringing infrastructure online, including dhcp, fileservice, DNS, etc.

By 6:50pm, most IRIS services were restored.

cronus.cs, one of our DNS and NIS servers, remains down at this time. This may cause delays or timeouts for various machines and services.

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.
