Resolved Incidents

EECS network border upgrade

by

On Monday morning at 7:00-7:45am, I will update the configuration on the EECS border routers to enable BGP peering with campus and bring new 10Gbps links into production.

Subsequently, I will enable direct connectivity between EECS and the Millennium research network at 10Gbps, allowing the research systems to use the 10Gbps uplinks as well.

I have spent considerable time testing the individual changes, and no discernible disruption of connectivity is planned. However given the complexity of the changes, I’m reserving a 45 minute maintenance window.

This work will affect all networks maintained by IRIS, including Soda, Cory, Sutardja Dai, BWRC, & BID, not including AirBears.

This upgrade has been funded in part by the RAD Lab and DETER projects.

EECS border route flapping

by

Following IST’s scheduled move of inr-201, the EECS border router experienced frequent route flaps affecting all outbound traffic, resulting in minor packet loss. Pending further investigation, traffic has been diverted to inr-202.

Mailing List Messages Delayed

by

The Department’s mailing list server, lists.eecs.berkeley.edu, ran out of memory last night around 12:45am. The service was restarted at 8:45am, and all delayed email has now been delivered.

More memory has recently been purchased and installed. The server will be reconfigured later this week to use the new memory. We hope this will resolve this problem.

Matlab license renewal

by

IRIS staff have been working for several months to renew EECS department Matlab licenses.

IST is responsible for license agreements with Mathworks and distributes Matlab license to individuals and departments. IST has assured us that our renewal has been processed, and that there is a 30-day “grace period” after the license expires on January 1st.

We understand Matlab is a critical tool for many researchers, and we are doing everything we can to prevent the license from expiring.

IMAP Certificate Validation Error

by

A new SSL cert was installed on imap.eecs on Thursday night. This unfortunately required a new “chain” certificate as Entrust is moving to 2048 bit keys (current keys are 1024 bits). Normally the IMAP server should present this chain cert to the user’s mail client so that the process would be invisible to the end user. However, the chain cert was not installed on the server initially, so the server could not present the cert, and clients were getting a certificate validation error.

Around 2:30pm on Friday, the chain cert was properly installed on the server and after that most of clients began working again. At least one user is still experiencing issues with Windows Mobile and Xpressmail.
