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.

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.
