Domain controller down

by

One of our domain controllers is down, causing intermittent problems such as taking a long time to log into your Windows account on the EECS domain. I have re-routed services to the remaining two. This should be resolved next week.

Network Maintenance Monday and Tuesday

by

As part of our network upgrade plan, we will be moving some switch up link fibers on Monday and Tuesday mornings from 06:30-07:30. There will be some brief outages to several Soda Hall nets during this time. I am expecting that these outages should last less than 60 sec. each. We appreciate your understanding.

Possible Security Breach

by

The UC Berkeley campus received an FBI report with evidence that
multiple computer accounts and systems was compromised in the time
frame of 2003-2005. The campus SNS (System and Network Security)
group believes that all evidence from the FBI report is consistent
with this being the UC Berkeley portion of the legacy of the
world-wide cyber attack by the infamous “Stakkato” alias. For more
information about Stakkato:

SNS forwarded information to EECS from the FBI report with what we
have identified as a copy of the department NIS domain
passwd file from November 18, 2004. This date appears to
correlate with activity via a compromised non-privileged user
computer account in EECS (this unauthorized activity was
presumably by Stakkato). Since Stakkato had access to very
powerful computing, Stakkato could have used “brute force” to guess
UNIX passwords.

Today’s Network Outage

by

We had a brief network outage this afternoon, from about 12:05-1:15 pm. A clerical error occurred in preparation for switching to the new network core hardware. This caused a VLAN to appear in the network core where it should not have been. This was the cause of the outage. My apologies.
