Scheduled Campus Wide Air Bears (outage)

by

Description: All control servers and access managers for the AirBears Network are going to receive a software upgrade on Wednesday, October 7, 2009, from 5am to 7am. There will be an initial loss of AirBears network service for the entire campus as the primary and secondary gateways are upgraded. Once the gateways are returned to service, there will be intermittent interruptions of service, from 10 to 20 minutes in length, as the access managers are updated and restored. The entire network should be returned to normal operation by 7:00am.

The only buildings not effected by this outage are Earl Warren Hall (2195 Hearst) and 2484 Shattuck, as they have a different authentication system.

The IST service status page for this incident is http://ucbsystems.org/?s=6399

Campus Wide Emergency Unscheduled Airbears Outage

by

Due to numerous reports of slowness that can be isolated to the primary AirBears gateway device, we will be reconfiguring the network to make the secondary AirBears gateway device the primary. This should not have an impact on authenticated users, but new users will not be able to get a login page during the outage. The anticipated resolution is 12:20pm.

IRIS Network Policy change: Local Switches

by

We’ve relaxed the portion of the [IRIS Network Policy](https://iris.eecs.berkeley.edu/30-policies/network-policy/) that governs use of local switches on the IRIS network.

You may now use almost any model of unmanaged Ethernet switch to connect multiple registered devices to any single network jack on the IRIS network. Additionally, local switches no longer have to be registered by serial number to a specific network jack’s Cable ID.

The [Helpdesk](https://iris.eecs.berkeley.edu/help/) has [recommended models](https://iris.eecs.berkeley.edu/30-policies/network-policy/best-practices.html#recommended-switches) of 5-port switches available for sale, and we encourage you to choose these; they’re known to work well.

Please review the [Best Practices](https://iris.eecs.berkeley.edu/30-policies/network-policy/best-practices.html#local-switches) for use of switches. Routers (including NAT,) managed switches (anything with it’s own MAC address,) and Ethernet hubs are still prohibited.

Soda 2nd Floor Network Outage

by

A switch failure disrupted networks on the Soda 2nd floor.

After seeing an alert at 11:20, network administrators discovered a failed management module in the 2nd floor switch. The module was swapped and the configuration reloaded. The switch was returned to service at 11:53am. Instructional support staff had to reboot several servers which had become stuck due to disrupted NFS traffic. All 2nd floor Instructional Labs were operational as of 12:30.

Mathematica 7 online seminar

by

The following online seminar invitation is extended to the EECS community.

Note that Mathematica 7 is now available on WINSWW, MACSWW, our Linux SWW, and on CD at the Helpdesk for loan.

—-

Mathematica has changed a lot over the past two years, and one thing I’ve noticed is that faculty often don’t realize all of the fields that it can be applied to and all of the amazing things that can be done with it. So I’d like to invite you to a free, online seminar called “Overview of Mathematica for Education,” where we illustrate Mathematica’s applicability in a number of different areas, from incorporating Mathematica into the classroom to parallel computing. Because Mathematica is available on campus to use for teaching and research, this seminar will help you better understand how to apply this versatile tool to your projects.

You can register for an upcoming session here:
http://url.wolfram.com/129U9-U/

Whether you’ve never used Mathematica before or have been using it for 20+ years, you’re sure to find this seminar beneficial, and perhaps even enlightening. During the seminar you can ask your own questions and get answers from the presenter or through the interactive chat.

If you’ve already attended “S01: An Overview of Mathematica for Education,” check out some of the other free seminars that are available to you: http://url.wolfram.com/1fVh3f6/

If you have questions, let me know. Otherwise, I look forward to “seeing” you there!
