Soda Hall Power Shutdown Tuesday 8/18 8am-8pm

August 12, 2020 by Derek Calderon

On Tuesday, August 18th, Soda Hall building power will be shutdown from approximately 8am to 8pm for required facilities work. There will also be sporadic brief outages to various IRIS services between 9am and 2pm due to network maintenance.

Our primary datacenter and network core will receive backup generator support and we generally expect all services to remain online throughout the day. However, we are taking the opportunity to perform a number of network maintenance items which would have otherwise necessitated multiple outages later in the year.

As a result there will be multiple brief interruptions to various services including NetApp file servers, DHCP and DNS service, and the login.eecs and winterm terminal servers. We expect each individual interruption will last for less than five minutes, and this work will be performed between 9AM – 2PM. This post will be updated when all network maintenance is complete.

After network services are fully restored, sysadmins may need to reboot their systems, restart/remount nfs file systems, etc. to get fully back online.

Making access to login.eecs “opt-in”

August 5, 2020 by Lars Rohrbach

The department unix login server, login.eecs, allows access for all EECS Standard account holders via SSH. Authentication uses one’s EECS username and EECS Windows/LDAP password.

Being open for all EECS users — even those who never intend to use login.eecs — increases our chance of being attacked by brute-force methods, or abuse by those with stolen credentials. In an effort to limit our attack surface, we will be restricting who can login on login.eecs.

Beginning Tuesday, August 11, SSH access to login.eecs will be restricted to members of a new LDAP group. Anyone who has used login.eecs recently has already been added to this group.

If you would like to utilize login.eecs, and have not yet been added to this access group, please email help@eecs.berkeley.edu to request login.eecs access.
