cronus down time – no NIS, time or DNS service Tuesday March 27, 2018 7am-7:30am

by

cronus will not be providing NIS, time and DNS services
starting at 7am Tuesday March 27, 2018.

A new server will become cronus shortly after 7am.

Though the scheduled downtime is 7am to 7:30am, we expect actual
downtime to be less. Devices on the IRIS networks
should be able to use rhea for NIS, time and DNS services
while cronus is down.

If you have any questions or notice any issues, please
contact help@eecs aka the IRIS help desk (395 Cory M-F 9:30am-5pm,
642-7777)

EECS Network Border Filtering Coming Soon

by

We plan on implementing greater security measures at the EECS network border in the near future. Specifically, ingress and egress filtering similar to what is described in RFC2827 / BCP38.

This filtering is designed to block two types of traffic:
* traffic leaving EECS, which has a source IP outside of valid EECS IP space
* traffic entering EECS, which has a source IP within EECS IP space

This will prevent spoofed IP traffic from entering or leaving the department network.

If your work or research relies on spoofed IP packets, in the ingress or egress directions, please contact us at help@eecs.berkeley.edu so that we can work with you to find a solution.
