LDAP & Jabber outage this morning, May 15, 2013

by

The department’s primary LDAP server ldap.eecs stopped responding early this morning around 12:30am. This affected a few other services which rely on ldap.eecs; we had reports of problems accessing Repo, and jabber.eecs stopped accepting connections at some point.

ldap.eecs was restarted at 7:00am and this would have restored most affected services. However, the jabber server seemed to be hung and had to be restarted; this was not noticed until around 10:30am.

Our ldap servers are aging and there is a current project underway to upgrade them to more modern hardware and software. An announcement about the scope of this project will be made in the coming weeks.

We are also planning to implement better monitoring of our jabber server so that future outages will be detected much more quickly.

Mailing list mail delayed over the weekend

by

The department’s mailing list server ran out of disk space late Friday, April 26, around 4:30pm. A single very large message to one list caused what should have been a temporary issue. I removed some unnecessary files on Friday and thought that everything was working normally, but this morning noticed messages were not being distributed.

The server was restarted and has since caught up with all outstanding messages. Because of this you may notice messages sent over the last 3 days just showing up in your mailbox today, but no mail has been lost.

An investigation is underway as to why our old monitoring software did not alert us to this problem sooner. A new monitoring solution is being deployed in IRIS and this server will be moved to this new monitoring solution as soon as possible.

Retiring web redirects on www.eecs.berkeley.edu

by

IRIS offers a redirect service for our account holders to forward their http://www.eecs.berkeley.edu/~username (and www.cs.berkeley.edu) web page to another location. This is typically used when an account is closed.

We promise this forwarding for one year after an account is closed, but have never done a bulk cleanup, and the list has grown quite large. As a first step to cleaning these up, we are now checking the destination URLs to make sure they are still valid. On 9am on April 30, 2013, the attached list of URLs will be removed from the server configuration.

If you have an update for any of these redirects, please contact the IRIS helpdesk.

[Note: In the attached list, the URL we are redirecting is on the left side, the destination is on the right, and the HTTP response code is listed, or -1 if the remote host cannot be found or does not answer.]

Web and mailing list server patching, Apr 10 at 7am

by

The department’s web server (www.eecs, www.cs), mailing list server (lists.eecs), wiki server (wiki.eecs), application server (apps.eecs) and jabber server (jabber.eecs) will be restarted Wednesday, April 10 at 7am.

On Tuesday evening these servers will have operating system patches installed which require a restart. They will be restarted automatically at 7am Wednesday morning and should be back in service by 7:15am.

These servers will now be patched (and rebooted if necessary) on the morning following first Tuesday of each month, the same schedule as our Windows servers.

Department Jabber (XMPP) server down for maintenance, Feb 13 6pm

by

The department’s Jabber / XMPP server jabber.eecs.berkeley.edu will be down for maintenance beginning at 6pm Wednesday, Feb 13, 2013. Total downtime is expected to be less than one hour.

During this maintenance window, the [Openfire server software](http://www.igniterealtime.org/builds/openfire/docs/latest/changelog.html) will be upgraded to the latest version (3.8.0), and the server will be moved to a new host. This is part of an ongoing project to retire old hardware and migrate services to more modern infrastructure.

If this downtime is very inconvenient for you, let help@eecs know as soon as possible.

IT Support During Winter 2012 Energy Curtailment

by

Due to the Winter Holiday, Energy Curtailment, and New Year’s Holidays, the Berkeley campus is officially closed for the period Monday, December 24 to Tuesday, January 1st, reopening on Wednesday, January 2, 2013. Additionally, many staff are expected to be out until Monday, January 7th.

All departmental computing servers will remain on and should be available during the break, but there will be no staff on site to provide any computing support or handle any requests. Automatic monitoring systems will alert staff to critical infrastructure problems, and any such problems will be dealt with on a best-effort basis. IRIS staff will be taking advantage of the holiday to do maintenance on some systems which will result in scattered outages, but any such downtime will be separately announced and posted on the IRIS website.

The IRIS Helpdesk will be closed beginning Friday December 21 at 3pm, and will reopen on January 2. Problem reports can be left on the Helpdesk voice mail (510-642-7777) or emailed to help@eecs, but staff may not receive or reply to these messages until January 2.

Requests for new IRIS accounts that are received after 3pm December 20 will be processed on January 2, 2013.

During the break, Instructional labs will be locked, but the main servers will remain online (imail.eecs, inst.eecs, cory.eecs, c199.eecs and fileservice.eecs). Instructional support staff will occasionally monitor inst@eecs email over the break. If you are unable to contact inst@eecs, you can leave a message at 510-643-6141. Please be aware, though, that staff may not be able to respond or reply to messages until January 2.

We recommend that all desktop computers be shutdown during the Energy Curtailment Period. If your Windows computer needs to stay on during the break, we recommend that you check with your system administrator to ensure that Automatic Updates are enabled with the option “Automatically download the updates and install them on the schedule that I specify” with a daily update schedule.

Computing support staff will be monitoring their email when possible, so please use standard email addresses to report any urgent problems. As a reminder:

* Instructional Computing Environment: inst@eecs
* Research / Staff Computing Environment: help@eecs

Enjoy your holiday break!
