Innocuous Returned Mail 2/25 1:03 PM – 1:12 PM

by

Due to human error, two of the departmental Mail eXchangers had a temporary problem between 1:03 p.m. and 1:12 p.m. PDT on Monday February 25, 2008.

In addition to the normal delivery to @ERSO.Berkeley.EDU, @CS.Berkeley.EDU, and @EECS.Berkeley.EDU e-mail addresses during that time, bounces were sent to the envelope sender typically with a “Subject: Returned Mail” and text about either “mailtest.cs.berkeley.edu: host not found” or “mailtest.EECS.Berkeley.EDU>… User unknown”

No email was lost. We are sorry for the inconvenience.

Network Maintenance 2/27 7:00 am – 8:00 am

by

There will be network maintenance at Soda 2nd floor on Wed Feb 27th between 7:00AM and 8:00AM. During this network downtime, both cronus and rhea will be off the network. Departmental NIS and time services will be down. Well-configured systems such as dhcp clients should be able to use their third DNS server during the downtime.

We expect the actual down time to only be several minutes but we are scheduling a larger window for the outage in case we encounter any unexpected problems.

Please make your plans accordingly.

AirBears/AirBearsBeyond Wireless Outage

by

AirBears and AirBearsBeyond service went down last evening and magically came back about 03:00 this morning. All clients were unable to get a lease. IS&T is investigating the Soda Hall Access Manager again as this has happened before in recent weeks and is still a mystery. All EECS WLANs were unaffected.

LDAP Server Issues

by

The departmental mail server (imap.eecs) and LDAP servers should now be working mostly properly. However, there are a few unresolved technical problems. You may encounter SSL certificate validation errors on our LDAP server (ldap.eecs and ldap.cs). As such, it may not be completely reliable for the remainder of today, and possibly across this weekend as well. We are actively working on solving the underlying problem, and will post an update as soon as we can.

No incoming or outgoing email was lost.

Technical background: Earlier today, the SSL certificates on our LDAP servers expired. This caused the LDAP daemon on ldap.eecs to hang, and refuse new connections. This cacscaded into a failure of part of IMAP system, and the IMAP daemon on imap.eecs similarly hung. We’ve managed to restart the daemons on both servers. Unfortunately, we’re running into a problem on the LDAP server, and are unable to install new, un-expired SSL certificates. As a result, we’re not completely confident that our LDAP servers won’t crash again, and take the IMAP server with it. Again, we’re continuously working on trying to fix this.

IRIS Website Offline Tonight for Server Migration

by

The IRIS website will be offline for about 30 minutes this evening (Wed Feb 06) in order to redeploy parts of the site using the [Mongrel](http://mongrel.rubyforge.org) HTTP server.

Currently, the portions of the site written in Ruby are being served using fcgid, which isn’t the most stable option. The switch to Mongrel will bring more stability to the site and be faster to boot!

Matlab License Renewed (until 2/2/09)

by

Due to a misunderstanding, IST thought that there was a 30 days grace period built into the license file, and so they thought the license file wouldn’t expire until 03/01/08. But as it turned out, that wasn’t true.

As a result, the matlab license server was down on 02/02/08 and 02/03/08.

The matlab license file has been renewed to 02/01/09.

We apologize for any inconvenience for the matlab downtime.
