All EECS instructional computers will be offline from Friday Jan 10 at about 5pm through Monday Jan 13 at about 10am Exceptions: Our email server (imail.eecs) and WEB server (inst.eecs) will be down only on Saturday Jan 11 from 10am-6pm. Email that is sent to the server during that time will be queued by the sender for later delivery. The EECS network will be down for maintenance on Saturday, so our computers will be inaccessible from the network and from each another. Any users on our systems would experience interruptions and possible loss of data. For more information about the EECS network maintenance, please see http://iris.eecs.berkeley.edu.
Starting the morning of Dec 19, some of our UNIX systems have denied logins or been missing the home directories. This is caused by a failure in LDAP authentication caused by some new certificates. This was fixed by 1pm today; please notify "email@example.com" (510-643-6141) if you are still unable to login to our systems. You can list our login servers at http://inst.eecs.berkeley.edu/cgi-bin/clients.cgi?choice=servers.
Starting the morning of Dec 5, logins at some workstations on 200 SDH (Macs) and 2xx Soda (Linux) experienced delays and timeouts. It is most noticable with Firefox and Chrome WEB browsers. If the WEB site you want times out, you can usually get it after clicking "Reload" a few times. The browsers may refuse to close when you try to logout. The sypmtoms are more severe on the Macs than on the Linux systems. We are trying to diagnose this will get help from the dept network staff on Friday. We'll post updates here.
The EECS network has been restored to service. Thanks to the EECS network staff for discovering the cause. The network problem occurred from 1:30am - 3:30pm today. It caused delays and timeouts for logins and for access to WEB servers and email servers on EECS computers. AirBears was down.

Printers that are spooled via the "iprint.eecs" server were down from about 8am Saturday (Nov 2) through 10:30am Monday (Nov 4). This includes the printers: lw199@iprint (lw199a@iprint, lw199b@iprint) in 199 Cory lw119@iprint in 119 Cory lwh30@iprint in 200 Sutadja Dai lw274@iprint (print274a@iprint, print274b@iprint) in 274 Soda lw330@iprint in 330 Soda lw349@iprint in 349 Soda All print jobs that were queued during that time have been canceled, and will not count against the user's print quota.
We are transitioning to new Synopsys licenses during October. The TecPlot program is replaced by the Sentaraus Visual (Svisual), and some functions of the INSPECT scripting language will no longer work. For details please see http://inst.eecs.berkeley.edu/cgi-bin/pub.cgi?file=synopsys.help. To give GSIs, researchers and students time to test the new Svisual features, we'll run the new licenses from about noon-6pm each weekday until Oct 25, 2013. After that, Tecplot will become obsolete. Please report questions or problems to email@example.com.
The Instructional email server refused incoming mail from 8pm on Thursday until 10am on Friday. All backlogged mail seems to be delivered now (10:30am Friday). Email that is refused is cached on the senders' computers and retried periodically until it gets through, so emails were delayed but not lost.
There was a campus power failure yesterday. (http://newscenter.berkeley.edu) EECS Instructional services were restored by noon today (Oct 1). Please report any problems to firstname.lastname@example.org
At about 8:15am, a transformer near Evans Hall broke and caused a power outage in Cory, Soda, Etcheverry, Sudarja Dai and other buildings. Soda Hall was closed until about noon. The computers, servers and networks for the instructional labs were restored to service by 2pm. There is a notice about the power failure on the campus IST Service Status page at http://ucbsystems.org/. This power outage was a result of an explosion in a manhole outside of Evans hall which damaged several high-power electrical cables. Campus reported that up to 15 buildings lost power completely and up to 30 more lost partial power.
Please see http://inst.eecs.berkeley.edu/End-of-Semester.
The National Instruments bus came to campus for the day and was visited by about 75 faculty, students and staff.
Yahoo donated 24 servers to instructional computing and bought pizza lunches for EECS students!
Please see http://inst.eecs.berkeley.edu/cgi-bin/pub.cgi?file=lab-safety.help for information about seeking help while you are in one of our labs.
- when you try to login the screen freezes - you see the error message "home directory is /" - session hangs up if you try to 'ssh' into an Instructional computer - unable to read WEB pages from the http://inst.eecs.berkeley.edu - lots of annoying "NFS timeout" error messages on your screen While the server is down, you may not be able to logout in our labs because you can't type any commands. On a SunRay, even turning it off doesn't log you out. The support staff check the labs after events like this to be sure everyone gets logged out. We also post information about the problem at http://inst.eecs.berkeley.edu to help students find out when the problem has been fixed. So all you can really do in this case is to wait until the problem is fixed, go back to the lab (or login to the SunRay server for that lab) and log yourself out, or let us log you out. We disable email receipt and relaying through imail.eecs when the home directory server is down. No mail is lost. Computers that send mail queue messages that are not accepted by a remote server, and they resend the messages periodically until they are received.
