Router changes

by

I will be disabling several 1Gbit Ethernet links between EECS and campus and Millennium and campus at 0830 on Friday. The traffic was previously migrated to 10Gbit links.

This is stage 2 of the EECS border upgrade project.

During the same maintenance window, I will be installing new line cards into the Soda Hall core router.

This is in preparation for upgrading the edge switches in Soda Hall.

No disruption is expected from either change.

(This work was completed without incident.)

New SSL Certificate for gateway.EECS

by

The current 1024 bit SSL certificate for gateway.EECS.Berkeley.ED will expire soon.

The current Entrust SSL certificate is being replaced by a 2048 bit Entrust SSL certificate that utilizes the Entrust 2048 bit L1B chain root certificate.

Our testing suggests that thunderbird, pine, Outlook, Microsoft Windows Mail (replacement for Outlook Express) and Apple Mail should be able to use the 2048 bit SSL certificate on gateway.EECS.Berkeley.EDU for outgoing smtp service using STARTTLS without any problems.

If you have problems sending email using gateway.EECS.Berkeley.EDU with the new SSL certifciate please contact the IRIS help desk (help@eecs, 395 Cory M-F 9:30am-5pm, 642-7777).

https://iris.eecs.berkeley.edu/15-faq/15-software/#Email has documentation on configuring various mail user agents.

Note, if your mail user agent can not handle 2048 bit SSL certificates, the outgoing smtp server on calmail.Berkeley.EDU still uses a 1024 bit SSL certificate.

Emergency router reload 5pm

by

The main EECS border router is stuck in a state that prevents either viewing or saving its configuration.

While monitoring the route table during the transition, a command used to examine the hardware routing table status caused the router a fair bit of consternation, leaving it in a state where it is impossible to save or view the configuration.

I will be rebooting the router at 5pm. All external connectivity to EECS will be interrupted, hopefully for a very brief period.
