New Print Server

by

With the ending of Microsoft support for Server 2008, we are moving a new version of print.eecs into production, running Server 2016, effective Wednesday morning, January 15, 2020.

All print queues have been migrated to the new print server, and lpd service as well, so existing print clients should not need any configuration changes, and should just be able to keep printing as expected.

If you do have any problems with printing via print.eecs, please report them to help@eecs, and we’ll attempt to fix them as soon as possible.

IT Support During Winter 2019 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 23 to Wednesday, January 1, reopening on Thursday, January 2, 2020.

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.

The IRIS Helpdesk will close early at noon on Friday, December 20, and will reopen on Thursday, 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.

Recommendation: Delay Upgrading to MacOS 10.15 (Catalina)

by

As with any major OS release, we recommend a cautious approach, especially where your primary device is concerned. Major releases often bring new issues or bugs, which may take some time for the vendor to address with patches and updates.

We have reports that Mac users who have upgraded to Catalina from a prior version of MacOS (or who have transferred data from a system using a prior version of MacOS) have experienced problems with wireless networking. In particular, users may see no wireless network SSIDs available, and users may be unable to connect to any captive portal wireless network (frequently used at public hotspots).

Intermittent Network Trouble at EECS Border

by

Staff are investigating intermittent disturbances in network traffic at or around the EECS border. We’ll provide updates here as we learn more.

Final Update 11/4 12:09:
This issue was caused by a DDoS or DDoS-style traffic which was overloading our firewall, which is near the end of its life. Using a number of active and passive mitigation techniques, we believe the impact of this traffic has been fully mitigated and there should be no further issues; the firewall has been stable since Friday morning. We are also accelerating the project already in the works to replace this firewall.

Oct 26 Planned Power Outage

by

We’ve been notified of another impending PG&E power outage scheduled to begin Saturday evening, October 26; campus Co-Generated power should take over, similar to the last outage earlier this month (https://iris.eecs.berkeley.edu/news/resolved-incidents/potential-campus-power-outage/)

We are planning to keep essential services up and running, including networking, fileservice, web services (people.eecs and group project sites), DHCP, DNS, login.eecs, WINTERM, and lists.eecs (maillists). Some redundant systems may be powered down (e.g. cronus will stay up for DNS/NIS, but rhea may be shut down).

We encourage everyone to shut down all non-essential systems at the end of day today (Friday). Any reduction in power consumption will make it easier to keep other essential services running.
