Evaluation of Workstation Ergonomics Now Required for CS Staff

All Computing Sciences employees who work more than four hours a day at
their computers must now have their workstation evaluated for ergonomic
factors. Previously, this was an optional evaluation, but in the latest
Performance Review and Development process, the EH&S section for
Computing Sciences was changed to make evaluations a specific

It now reads: "Complete a workstation evaluation if working on a
computer four or more hours per day (a) at the time of employment and
(b) following an office move. Each employee is expected to be proactive
in ensuring that the recommended workstation modifications (if any) are

Like other required training, this requirement is listed in the
employee's training profile. To view your training profile, go to
https://training.lbl.gov/default1.asp and log in using your LDAP name
and password. For questions or assistance with your training profile,
contact Computing Sciences Safety Coordinator Martin Dooly, at

To schedule an evaluation, contact Computing Sciences EH&S Liaison Kam
Tung at KFTung@lbl.gov.

New Feature: Latest CS Job Postings and a Reminder About Rewards for Referrals

Beginning with today's edition of InTheLoop, the CS HR staff will
feature some of the top job openings in CS' three divisions. Employees
are also reminded that the Lab's Employee Referral Incentive Program
(ERIP) is still in effect and pays $1,000 (net) to employees who refer
successful candidates. For ERIP details, go to
http://www.lbl.gov/Workplace/HumanResources/ERIP/index_erip.html. To
qualify for the ERIP bonus, candidate resumes must be submitted to
central HR, not through CS recruiting.

This week's top CS job listings (and links to the postings) are:

NERSC Division:

Advanced Systems Group Leader

Server Team - Systems Administrator


Information Technologies and Services Division:

Database Specialist, Information Systems and Services Department

Web Developer, Information Systems and Services Department


All Current job openings in Computing Sciences can be read at

And Now -- It's the Gaobot Worm

A new worm, W.32.Gaobot, has been attacking Windows systems intensively.
This worm spreads through shares by either entering a blank password for
the Administrator account or by running a password cracking attack
against accounts such as Administrator, Guest, owner, and others. Once
it connects to a share, it installs Trojan horse programs, woinggg.exe
and sysldr32.exe or sysmgr.exe, in the system32 directory of the victim
system. It then creates an outbound connection on TCP port 9900 and then
scans other systems on TCP port 445. Gaobot is a very serious threat.
Your best recourse is to ensure that you do not share your Windows
system's hard drive if you do not need to, that all accounts on your
system have strong (difficult-to-guess) passwords (visit
http://www.lbl.gov/ITSD/Security/guidelines/password.html#choose for
guidelines concerning how to create good passwords), and that your
system's anti-virus software is up-to-date.

New LBLnet Port Blocking Is in Place

Several worms (see preceding article) have compromised a large number of
Windows computers recently. The worms all attempt to gain access to the
"Admininstrator" account and others through ports 139 and 445 by
entering several trivial passwords (including no password at all). These
ports are used for Windows network file sharing. Because of the current
high risk (which is growing because new, more powerful variants of these
worms are surfacing) and the small amount of LBLnet traffic that
utilizes ports 139 and 445, traffic bound for these two ports is now
being blocked. This block will stay in effect for at least two weeks, at
which time the risk will be reassessed. The Computer Protection Program
apologizes for any inconvenience this interim solution may cause, and
urges you to contact the Help Desk (help@lbl.gov or 486-HELP) if you
need assistance.

About Computing Sciences at Berkeley Lab

The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.

ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 7,000-plus scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are Department of Energy Office of Science User Facilities.

Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
