DOWNTIME - 3/28/2015 - All Day - FAB LL South Networking
Written by Janaka Jayawardena   
Tuesday, 24 March 2015

Our final major network renovation happens on Saturday, March 28th.  The downtime will begin at 10am and could last all the way through 10pm due to the network closet complexity of the affected areas.  Outages will be concentrated in the South part of the FAB Lower Level and affect:

FAB 25-01 - NEAR Lab

FAB 60 - ECE lab areas

FAB 82 - CAT suite

FAB 85 - ECE office areas

FAB 88 - CS lab suite

FAB 89 - ECE lab areas

The work being performed only affects the network closets driving these areas. The rest of FAB should not be affected.

We are finally ready to try the web server operating system upgrade that was postponed last year. On the evening of Wednesday, March 25th, under cover of the systems patching that will be taking place at the same time, two web servers will be upgraded to the current version of Ubuntu Linux supported by the CAT - Ubuntu 14.04 (Trusty Tahr).

This change will affect all websites at:

and many “project” websites that are hosted by the CAT.  This change could cause some issues for websites running code written for older versions of PHP.


Google Chrome profile changes for MCECS Windows users

We are going to change where Chrome stores its own “profile” information by placing it in your N: drive where there is more storage. This is to address some User Profile overflows caused by new versions of Chrome.

Logging in to our supported Windows systems AFTER late Wednesday (March 25, 2015) will transition you to this new scheme. You may experience some “slowness” during your first login after this date. This is because it is copying the data to the new location and changing settings.


DOWNTIME - 3/25/2015 - 6pm - Patching all UNIX/Linux Systems

Monday, 23 March 2015

We will be patching all our UNIX/Linux systems on Wednesday evening (March 25th, 2015).  The work will begin at 6pm and could last as long as 10pm. While end-user Linux systems will see direct reboots, the environment will be unstable during the work as various back-end services will be rebooting as well.


Spring Break Downtime - EB 325 and FAB 55-17 MCECS Computer Labs
Written by Janaka Jayawardena   
Tuesday, 17 March 2015

The two main MCECS Computer Labs (EB 325 and FAB 55-17) will be unavailable for much of the week of Spring Break (March 23 to March 27). We will be going through the lengthy process of replacing all the computers in those labs.

We expect FAB 55-17 to be unavailable first (starting Monday - 3/23/2015).  EB 325 will be down starting on Wednesday (3/25/2015).  We hope to have everything done by the end of the week.  (It is likely that FAB 55-17 will be back in service for users first.)

During this time, the CAT will be extremely busy.  If faculty have any software requests for Spring quarter, please get these in this week if possible.  If we are unable to get to your request before the lab reconfiguration, it may need to wait until the week after the break.

Urgent Alert for owners of Lenovo laptops
Written by fester   
Saturday, 21 February 2015

If you are the owner of a recent (as in mid-to-2014 to Feb 2015) Lenovo Laptop AND you are using the original Windows load that came with it, you may be affected by a dangerous piece of adware (called “Superfish”) that comes preloaded with the operating system. This adware can be compromised to eavesdrop on a user’s secure web communications.

You can check if you are affected by visiting this website from your Lenovo laptop (from each of your browsers) and waiting while it performs a check:

After pressure from various quarters, Lenovo has agreed to provide a removal mechanism for this adware. If you have received a Lenovo laptop recently, go through this Lenovo advisory and use their removal tool if you are affected.

Microsoft has also provided a Defender update to neutralize superfish (although it may leave Firefox still vulnerable).

The CERT announcement about the vulnerability is here:

A more disruptive (but thorough) fix is to reload your laptop with a clean Windows load (not supplied via the Lenovo recovery mechanism).
