LIGO I Construction/LIGO Laboratory Administration (Lindquist)

LIGO Weekly Site Telecon (Lindquist)

A site teleconference was held on Thursday, October 9, 2003.  The following were among the issues discussed:

Action List  - Ed Jasnow is ready to implement the convenience checks for Livingston..

Budgets  - A FY 2004 budget model has been distributed.  I have received some comments from Florence and from Alan Weinstein.  There is no overt management reserve in the model.  We estimate $6 million of carry forward, and all $6 million has been allocated to tasks remaining from FY 2003.  However, delaying HAM Seismic Isolation work into FY 2005 will defer approximately $1 million.

EPI - The last of the EPI contracts that required NSF review and approval are out to the vendors.

Property - The trailers (plus some miscellaneous other equipment), will be posted for sale this week.  If they are not sold in two weeks the will be "abandoned," which means that the government will have to haul them away.
The list of current actions revised to reflect the status of open actions assigned through August 28, 2003 may be found at ACTION LIST.

LIGO Hanford Observatory (LHO) and Interferometer Operations (Raab)

Summary of Commissioning Activities at LIGO Hanford Observatory  (compiled by L.Matone)

H1

In the past week, H1 has been running in high sensitivity mode with all of the angular
DOF locked. However, the lock stretches have been observed to be only  4-6 hours long and
we are currently investigating the reason for these short stretches.

The inspiral range has been observed to vary from 1.7Mpc to 1.2Mpc (see elog). This was
due to non-stationary peaks around 100Hz coming from the ITMY (and X) bounce
modes (the "3-fingers" problem, see log). Despite the non-stationarity, signs of improvement
in acoustic coupling were seen due to the table work on the reflection port from last week (see elog).

The "3-fingers" problem was then resolved by adjusting the power recycling loop gain (see elog) which
eliminated the non-stationary behavior. Our current displacement sensitivity is shown in this elog which
also compares the sensitivity from a few months ago (note that the vertical scale is in m/rHz).

Measurements on frequency and intensity noise were also made (freq noise, intensity noise)
and they were found not to limit our sensitivity.
 

H2

Just like H1, we replaced the EO shutter on table ISCT7 with a rotable half-wave plate (see elog).
The Guoy phase telescopes were adjusted for WFS2 (on reflection), WFS3 and WFS4 (see elog.).
The Guoy phase telescope for WFS2 on POY was designed (see elog). All of the WFS loops were
successfully closed (see elog).
 

LIGO Livingston Observatory (LLO) and Interferometer Operations (Zucker)

LLO (Zucker et al)
---------------------------------------------------------------------
(some contributions missing due to LLO disk crash and GC net outage)
 

Interferometer commissioning:
--------------------------------------------------------------------
Tough week on L1. We now have robust locking during nighttime hours, but
have an excess noise problem which is proving difficult to track down.
It seems to originate somewhere in the common mode frequency control
system and only manifests itself when the interferometer is in
operation; off line, every component checks out fine. We have tested
numerous theories and are currently probing for a subtle nonlinearity
that could be associated with some recent electronics mods; in theory
this looks like a good candidate and could be easy to fix, but at this
writing it's too soon to tell.  Rana, Pradeep, Valera and Andri are on
the problem for tonight.
 

In the meantime we've made significant progress on many other fronts
(check the ilog for many more):
 

o Stefan Ballmer, Brian O'Reilly and others calibrated and tested shot
noise sensitivity for our new dark port "running" photodiodes; Rana and
Stefan were able to successfully hand off from the acquisition diode to
these as required for our eventual power up.
 

o Brian and Rus installed the new ETM Dewhitening filters and
characterized them. These should allow a bigger noise margin than S2-era
dewhiteners at high frequencies.
 

o Matt Evans, Rana Adhikari, Rupal Amin and Gaby Gonzalez have made
significant progress on the WFS control matrix. Due to the above problem
we didn't get to try full WFS control out properly before Matt took off.
 

o Matt also wrote an automatic lock-in servo script which processes the
alignment dither (a method borrowed from LHO last week) to automatically
converge arm alignment at the push of a button. Still in "beta test" but
the demo was slick.
 

o Pradeep Sarin, Rupal Amin and Valera Frolov tuned up the mode cleaner
wavefront sensors (MCWFS) and built new digital control filters. The
mode cleaner holds alignment like a rock now, doesn't even notice the
nightly trains.
 

o Rich Abbott and Flavio Nocera (by phone) diagnosed an oscillation
problem with our new intensity stabilizer (ISS).
 

o Rolf Bork flew out to help Chethan Paramesewariah debug a nasty timing
bug in the end test mass EPICS processors. After exhaustive round-robin
component, code and location swaps it was traced to an apparent bug in
the MVME162 microprocessors themselves (probably only certain vintages,
as the problem was never seen at LHO). Today they recompiled the code
for MIPS CPU's and substituted these for the 162's, solving the problem.
 

o Rai has done significant work to modify and characterize the new Coil
Readout filter boards. These allow high-SNR readback of the actual
forces applied to the test masses during low noise operation. In the
process Rai also fully characterized all the new ETM electronics and
blessed their quietness.
 

o Harry O and Gary T have installed the LHO damping kits on all of our
periscopes and installed the new super-rigid periscope shipped from MIT
onto our dark port.  A second unit slated for the REFL port turned out
not to fit without modification, so we backtracked to the original.
 
 

Safety and security (Riesen)
--------------------------------------------------------------------
Completed weekly IR scans on PSL and IO/ISC tables, found zero
errant beams.
 

Weekly site tour gave no concerns or reports.
 

Continuing work on the revised LLO Laser SOP.
 
 

CDS Software (Khan)
--------------------------------------------------------------------
1) Developed and tested the Mode Cleaner Autolocker perl script.
 

2) Developing a method for monitoring the UPS
 

3) Developing scripts for XArm and YArm autolocking
 
 
 

Commissioning (Traylor)
--------------------------------------------------------------------
Installed constrained layer dampers on all of the ISC and IOT periscopes.
Completed the installation of the new and improved AS periscope on ISCT4
after modifying the mirror mounts and machining new shims for the mirror
mounts.
 
 
 

Commissioning (Peter King)
--------------------------------------------------------------------
 

I have been trying to diagnose the optically contacted pre-modecleaner.
After sorting out a few minor problems associated with running an NPRO
laser at low power, I managed to align the pre-modecleaner.  I did not
see any of the errant beams that were reported last month; either with
an IR viewer, IR flashcard or both.  It also checked out with the green
HeNe laser.  In short I think the cavity is okay but cannot explain what
was observed previously.
 

I tried to find out where New Focus get the cases for the photodetectors
in the hope of being able to use a similar package but apparently they
are custom made.  Whilst the prototype is packaged and heatsinked,
assembly and disassembly is not very convenient.  It may require a
designed housing.
 

Shally Saraf is coming down next week to fabricate the approx. 100 mm
round-trip length ring cavity.  All items are expected to be in hand by
tomorrow.
 

Commissioining and HEPI electronics (Abbott)
--------------------------------------------------------------------
1.  Finished all electronics for valve calibration stand.  7 units are
to be produced per Jonathan Kern.  All metal work, parts ordering, and
PCB ordering has been completed.  Units to arrive soon, and be sent to
stuffing house.  I opted to see the units first instead of sending them
directly to the stuffing house.  In the future, I will send them
directly to the stuffing house along with the necessary parts.
 

2.  Design is underway for the seismic interface chassis.  Received
prototype chassis for use in the design, and it looks good.  I will be
sending around the schematics as they are completed.
 

3.  Modified the ISS board to cure a crossover related instability.
System performing well.
 

4.  Tested a prototype FSS card with enhanced high speed HV amp.
Achieved ~500 kHz UGF, but design is far too prototypical to install
this close to a run.
 
 

Commissioning (Gretarsson)
--------------------------------------------------------------------
Made a simplified interface for getting RDS and NDS data to a Matlab
workspace including the workspace of functions (not possible e.g. with
DataLoad).  The GUI is called "datapuppy" and the idea is basically to
make getting small amounts of data (be it live or from a previous run)
into Matlab totally trivial, even for a complete newbie.   Should be
available on from the Matlab command line on GC at LLO by S3.
 
 

LLO Seismic retrofit (Kern)
--------------------------------------------------------------------
All of the drawings for manufactured and machined parts have now been
released for production.  Working with Linda T. to complete the last
large contract, however the shop has been given the go-ahead.  The
machine shop manufacturing complete sets of parts for 12 actuators by
November 14 still seems to be on schedule, have had a few conversations
with the manufacturing engineers at JPL and should have a milestone
spreadsheet completed this week. Sent the parker valve test manifold
back to the shop for manufacture and installation of sleeve bushings in
the plug valve bores.  Ordered misc VCO fittings from Whitey valve.
I've reported the difficulties we've experienced using SolidWorks,
managing the integrated models of the HEPI/HAM and HEPI/BSC. I have
installed PDMWorks on a local server. PDMWorks is a digital analog of
old fashioned 'flat files' in drafting rooms, keeping track of who is
working on what part of the model as well as revision history. We've
archived the LLO Seismic retrofit to a PDMWorks vault.  Ken Mason is
here to go over the integrated model with us, and we've arranged for a
tutorial on S
 
 
 

Interferometer commissioning, AdLIGO simulation, and data analysis (Franzen)
--------------------------------------------------------------------
1) Weili Ke and myself finished installing the f2p filters. See our
entry in the e-log on Oct.2 for a summary. We would still like to fine
tune the actuator coil gains a little if given a window of opportunity
and if it is judged to be worthwhile to do it.
 

2) I have prepared and tested scripts for running a WaveMon LLO S2 veto
analysis on alvar. However, some S2 data is still not available on this
machine. Igor is now fixing this.
 

3) I resumed my AdLIGO MC simulation work using MELODY.
 

Detector/Technical Support (Coyne)

40 Meter Interferometer (Weinstein)

• Commissioning (Miyakawa, Kawamura):
• Osamu and Seiji re-measured the PSL frequency noise using the mode cleaner, and the new procedure outlined in T030239.pdf. After some time trying to reconcile a difference in normalization between the old procedure and the new, they determined that the new procedure is more reliable, and the old method had a couple of mistakes in the normalization; the old noise curves were underestimated by a factor of around 2.8. With the new normalization, the frequency noise still meets specs above 50 Hz, except for a set of acoustic spikes in the 200-1000 Hz range; the re-layout of the PSL (reducing the number of folding mirrors and placing the FSS pickoff after the PMC) has improved things considerably areound 800 Hz and above 1 kHz. The noise around 100Hz is lower due to the dewhitening filter in the MC2 suspension controller. The peak at 180 Hz noticed last week is now gone.
• Osamu and Seiji used the transmission of the 33.2MHz sidebands to re-measure the length of the MC, and found it had changed by 5 Hz (out of 33.2MHz) during the vent; ie, not at all. They also find that the detection of the 33.2MHz sidebands is shot-noise limited, even if the MC length varies by the equivalent of 40 Hz.
• Osamu and Seiji are now working to understand the origin of the large (as much as 8%) intensity variation in the MC transmitted beam. The PSL intensity servo cannot be commissioned until this anomalous intensity variation is eliminated.
• LSC Electronics (B. Abbott, Heefner, Taylor)
• Mohana installed the LSC auxiliary controls target code (c1iscaux), operator screens and databases. The lsc aux database has been loaded on the processor and everything appears to be OK. The XY212, VMIC 3113A and VMIC 4116s addresses were set. Jay and Ben checked all auxilary controls for the LSC system, and they are operational.
• The next step will be to inject signals into the LSC front end ADCs and propogate them through the code. If all goes well and all field cabling is completed, the system should be ready operation by the end of next week.
• In the process of checking out the LSC analog boards through the auxiliary controls, Ben smoked two LSC PD Interface boards. The problem was found to be a bad cable on the XY212 that was connected to both boards. Replacements are being obtained from Todd.
• The processor for the LSC front end was replaced and the system appears to be a bit more stable, but still crashes every once in a while.
• Ben moved the PZT Drivers to 1X3 to get them away from the analog crate where they were originally placed.
• Bob and Art continue to work on cross connect and internal rack cabling for the LSC and ASC, as well as the cables to the photodetectors. They can get 5000 ft folls of SpectraStrip multi-conductor twisted-pair cable, for the long runs. They are making great progress.
• Bob and Art powered up the LSC/ASC analog rack (1X2) with the Kepco linear power supplies, and discovered that the WFS demod boards are power hogs. We'll need to buy more power supplies to keep those boards happy, but we won't need them for a while.
• Digital suspension controllers (Sakata, Goggin, B. Abbott, Heefner)
• Ben has balanced the electronic offsets on the MC2 coil dewhite board. So, switching from mode cleaner lock acquisition mode (dewhitening turned off to increase dynamic range at the expense of noise, to make lock acquisition robust) to low noise mode will not disturb the optic.
• Jay and Ben have checked out all the whitening / dewhitening switches on the XYCOM screens for all the suspension controllers. Finally, they all work as they should.
• Ben redrew the schematics for the end station wiring to reflect recent changes to the layout. They are now a current representation of the as-built condition.
• Shihori continues to make DTT spectra of all the core optics OSEM sensors, to find and diagnose problems. Most of the problems she is encountering are in DTT!
• Lisa and Shirori (with help from Ben) re-did the input sensing matrix for the MC optics, in an attempt to fix the intensity variation problem in the MC transmitted beam. But, it didn't help. Now she's re-doing the output coil matrix for MC2. Lisa is documenting the diagonalization procedure that we have been using.
• PSL:
• Flavio cannot commission the ISS servo until the large intensity fluctuation mentioned above is fixed.
• Meanwhile, he finished installing all the permanent cables and DAQ channels.
• Rolf has a list of all the ISS DAQ channels, and will need to modify the code running in the c1iovme processor to read them in and make them available to DAQ, etc.
• Mike has the info he needs to update the PSL table layout with the locations of the ISS photodiodes.
• Optical levers (Kawazoe, Heefner, Abbott):
• Jay used DTT to measure the transfer function from The OLYAW_EXC input to the OLYAW_IN1 TP for ETMY. The transfer function was as expected, flat to a peak at ~0.6Hz and then falling as f^-2. Foton was then used to generate filters for a DC coupled OL servo. The servo was engaged and appears to work. The same filters were installed on PIT and the optic damped in PIT and YAW using only the optical levers. The filters used had poles at 0.1, 100, 100 and zeros at 0.5, 0.5.
• Fumiko continues to refine her calibration of all the oplev QPDs in terms of angular displacement of the optic, in radians. She is now working on getting calibrated angular motion spectra, and comparing with the detector system noise and dynamic range.
• Ben increased the gain in the Oplev photodiodes by a factor of 10 as is called for on Note 2 on its schematics.
• Optical sensing (Smith):
• PZT1 STEERING MIRROR: Awaiting repair by Piezojena of the PZT1 pitch amplifier.
• ELECTROOPTIC SHUTTER: Awaiting delivery of 3rd EOS.
• QPD MOUNTS: Awaiting delivery of mounts.
• POX and POY: A preliminary ACAD optical layout for the POX and POY beams was completed. The design of the focussing lenses for the QPD, video camera, LSC, WFS, and power meter paths is in process. The final choice of lenses will require a slight change of the path lengths and component locations.
• INITIAL POINTING: A mount for the 10 X telescope in the initial pointing ANG beam was designed; working drawings were completed and will be released to the DCC.
• Mike is updating the ACad drawing with the as-modified PSL table.
• Computing:
• We continue to have lots of problems with DTT. It only runs on one computer (op140m), but not on op240m or dmt140m. With Peter Shawhan's help, we suspect that the problem is with the way op140m NFS-mounts the disk that has the DTT executable libraries.
• Even on op140m, it often freezes, gets out of synch with the data, or fails to access test points. Alex Ivanov is trying to figure it out, and in the meantime, showed us how to release and set test points manually.
• Alex also changed the GPS IRIG B slave in the AWG, which helped with the synch problems.
• Meanwhile, it is clear that our online computers, which are Blade 100's, are not up to the task of running DTT, Dataviewer, many copies of medm, etc. We are trying to get one or two surplus Sun 450's to replace these machines.
• Modeling (Miyakawa, Kawamura):
• Seiji continues to use his Finesse model of the 40m to study lock acquisition. He tried to use the scheme employed at the Garching 30m, using non-resonant sidebands to robustly lock the PRC (l+). He found, again, that the desired locking point has much sensitivity to the position of the SRM and Michelson degrees of freedom (ls and l-). However, it may be possible to lock l+, and keep it locked while acquiring lock on ls and l- in a second step. He is investigating.
• South Annex Bake Ovens (Taylor):
• Bob continues to keep an eye on the 40m vacuum system while Steve is on vacation.

Bob continues to spend most of his time cabling the LSC/ASC racks.

LASTI (Ottaway)

HEPI Progress (McInnes, Mittleman)
 

  The hydraulic plumbing has been completed and leak check by the
installers. We are in the process of transferring the 8 hydraulic
actuators from the BSC to the HAM and hope to have fluid flowing by early
next week.
 

LASTI Planning
 

A LASTI reveiw will be held at the LSC meeting, hopefully the issues such
as weigh budgets and cavity configurations can be settled there.

Data Analysis and Computing (Lazzarini)

---------------------------------------------------------
LIGO Data Analysis and Computing (Anderson for Lazzarini)
---------------------------------------------------------
-----------------------------
LDAS Software Team (Blackburn)
------------------------------
 

Focused on closing out critical and important problem report over the
past week. More than 50 problem reports were closed out. There still
remain 2 critical and 20+ important to be addressed before the release
next week.
 

The Standard Template Library's string class has been identified as one
of the major contributors to core dumps in the frameAPI. We have written
our own substitute string class which is thread save. It has partially
been integrated into the frameCPP code as of this week and has greatly
reduced the rate of core dumps on the LDAS TEST system where it is
primarily being tested. We will continue to advance the integration of
this new string class for the release, but have not committed yet to
using the optimized level of inlining that this is intended to fix in
the science run. Without the optimization, we are seeing only about
40% of the performance in the frameAPI.
 

A bug was discovered in the LDAS user account cgi script which caused
it to report to the database that new user account were created when
in fact they were not. This has been fixed and the user accounts at
the sites and in the database synchronized.
 

Developed a new test to validate that the frameAPI does not corrupt
data. This test will be run tens of thousands of times before the LDAS
release to verify that no data corruptions is taking place.
 

On Monday we commenced the mock data challenge for S3 data reduction.
Three levels of data were being produced at LHO and LLO on Mon-Wed (LLO
has stopped producing reduced data at the moment because of problems with GC
servers. It should be back online today). Level 1 reduced data is being
produced at a rate about 1.7 times faster than real-time while it is
catching up to the current time. Level 2 (AS_Q, DARM_CTRL and EXC channels)
and Level 3 (AS_Q only) data are being produced several times faster than
real-time. The server outage at Livingston and the harddisk failure in the
CIT archive have caused testing to temporarily pause at these two sites.
 

After some initial problems with installation, the new LDR has now been
successfully installed on all machines (cit, lho, llo, mit) by Hari this
morning and we will be publishing data to LDR today.

E2E Weekly Physics Meeting
----------------------------
Luca and Matt described current status and problems at sites.
Matt explained his ezlockin script.
 

At LLO
-----------
(Matt) Worked on ASC system at LLO.  Also developed generic script for system
 diagonalization (ezlockin).  ezlockin can be used to diagonalize drives,
 align cavities, and generally decouple bilinear degrees of freedom.
 

WFS
--------
(Biplab) Large changes in demodulation angle for differential heating in two
 arms have been observed in simulation. For example, for change in temperature
 only in Y-arm from a state half-way between "cold" and "Final hot" state,
 while keeping X-arm in "Final-hot" state, the demodulation angle for WFS2 signals
 for rotations in the recycling mirror changed by about 0.4*pi=72 degrees, while
 the maximum value of the signal increased by about 33%.
 

Code development and maintenance
---------------------------------
(Melody) Performing code cleanup for the framework to do the on-the-fly
 compiling & dynamic linking.
 Extending the code base for a 1x1, 2x2, VxV, and 2VxV new FUNC primitives.
 

Alfi
--------------
(Bruce) Attempting to track down a difficult edit-window initialization problem.

Data Analysis Activities (Anderson)
-----------------------------------
 

Shawhan:
 

* Looked at loud inspiral event candidates found in the H2 S2 playground
  data, and tried to find veto conditions which could eliminate them.
  I found that a veto condition using LSC-POB_I with a certain band-pass
  filter was very effective for some of the event candidates, but there
  were others for which I could not find any good veto condition.
 

* Went through the LHO trend data from S2, checking the Epics channels
  which indicate timing problems in the front end.  There seem to have
  been some problems.  Waiting for advice from Dave Barker and/or Rolf
  Bork to see whether any data should be excluded from analysis because
  of these problems.
 
 

Reilly:
 

* In preparation for running the sgwb DSO on the recently released ldas,
  I recompiled lal and lalwrapper under RH9 on ldas-pcdev1.  I also
  compiled the standalone wrapper there.  After some debugging of
  the DSO (removing printf statements) I was able to get it to
  run on the new system and I was able to test the frequency masking.
  All necessary preparations were made to *finally* get through the S2 data
  set but the ldas system seems to have a bug which cause the frameAPI
  to shutdown during my jobs. The cause of this problem is still unknown.
  Further delays are expected because the file system used by ldas-cit
  has crashed.
 

Yakushin:
 

* Finished working on using the calibration data in the waveburst.

LDAS System Administration (Anderson)
-------------------------------------

Caltech
-------
(Dan Kozak)
 

* Encountered "stuck" file in archive (ls -l of it would hang), rebooted
  ldas-archive, ran samfsck, got it working again.
 

* Got QFS licenses for new gateway boxes at LLO/LHO (waiting on a permanent
  one for MIT)
 

* Relabeled tapes in archive to make obsolete (9940A format) tapes
  available again.
 

* Migration from 9940A to 9940B format tapes continues.  We've got 6%
  left to go as of this writing.
 

* Continued to copy E7 data from HPSS.
 

* Finished copying all S2 L1 RDS files from IDE-RAID into SAM-QFS.  Am now
  doing some housekeeping work in order to ship tapes to the observatories.
 

* Recovered from failure when a 3510 disappeared from the FC fabric and
  the FC switch reset it's port (i.e. a piece of the filesystem
  disappeared).  This involved finding the data that had been corrupted
  and ensuring that a good copy went into the archive.
 

* Fixed stuck silo robot.
 

* Started copying RDS from IDE-RAID into SAM-QFS at LLO.
 

* Tracked "stale inode" message at LLO--a benign message as best I can tell.
 

* Assisted with exporting tapes from silos at the observatories for the MDC.
 
 

(Hari Pulapaka)
 

* Installed the old LDR on test machine and tested the RDS publish
  script. Ironed out a few bugs in it.
 

* Requested certificates for all the hosts in the MDC run and installed them.
 

* Installed LDR on the hosts in the MDC run.
 

* Publishing data as a part of the MDC run.
 
 

(Al Wilson)
 

* Installed RH9 on ldas-pcdev1 and m26 .
 

* Replaced motherboard in 3 pc's: datacachetest1, ldasbox4,5.  The new board
  so far is working just fine.
 

* Rack mounted pc's and cleaned up cables in 215 Synchrotron.
 
 
 

(Stuart Anderson)
 

* Upgraded several LDAS servers (hardware and software) in preparation
  for S3.
 

* Upgraded all the Lab LDAS systems to a pre-release version for the
  currently ongoing Reduced Data Set (RDS) Mock Data Challenge (MDC)
  which is testing our ability to generated reduced frame files
  and distribute them throughout the collaboration.
 

* Testing replacement motherboards for IDE-RAID and stand-a-lone
  Linux LDAS development machines. The initial results are very
  positive. If no errors are found during weekend testing all
  ~20 of these systems will be upgraded.
 
 
 

MIT
---
(Keith Bayer)
 

* Installed SSH patch on gateway machine.
 

* Installing cable trays when possible.
 

* Installing 280R new gateway server.
 

* Moving cables into existing trays in ceiling when possible
  enoki / lancelot back in production DMT mode .
 
 
 

Livingston
----------
(Igor Yakushin)
 

* This week we are running MDC to test the raw data
  archival and RDS generation.
  Several problems have been uncovered as a result.
 

  a) dd that is used in Ben's script to copy raw data
     from /frames to /samrds worked extremely slow at LLO
     (but not LHO) unless one changes the default block
     size. Currently I am using bs=128k.
  b) The current version of diskcacheAPI has trouble learning
     about new directories added to MOUNT_PT. To fix this problem
     Phil had to increase the number of threads from 2 to 8.
  c) Ben's script copying raw data crashed. Ben has
     fixed the bug.
  d) Yesterday the whole GC system went down and as a
     result we can no longer run createrds script on
     ldas-jobs since it uses NIS and mounts user accounts
     from GC. It is down until GC problem is fixed.
 

* I tried running DB2 administration server under RH9
  and so far was unable to do so. Without it we cannot
  use replication.
 
 
 

Hanford
-------
(Ben Johnson)
 

* The new 280R gateway server has been installed and has been working
  as the ldas/gateway box during the MDC this week.
 

* I have now been set up as part of the GC dsorun group. I can now
  administer and run createRDS jobs on the ldas-jobs box at LHO.
 

* The disk2disk copy script (/frames -> /samraw) has been copying data
  for the MDC this week at both LLO and LHO. I have been working with Igor
  on getting rid of bugs in the script.
 

* I have also been working on scripts to allow for easy monitoring of
  the  archiving processes; disk2disk copying and archiving+staging in samfs.

Hanford:
(Christine)
 

-  It's been a very busy week.  Our network has been bombarded with
pings followed by short bursts of TCP packets originating from about 100
different IP addresses.  Most of the ip addresses were dhcp addresses
from Stanford University.  I sent an e-mail to ITS Security at Stanford,
but just received an automated e-mail back saying they were so
overwhelmed with computer security issues they would try to get to my
problem.  There were also ip addresses from Germany, Japan, Mexico, and
several USA ISP companies.  I started blocking the ip addresses at the
router firewall, but it was just too many.  As soon as I would block one
batch of addresses another batch of new addresses would show up.  At
first it looked like they were just targeting my dhcp server, so I got
dhcp running on another computer, took my original dhcp server off the
network, reinstalled the Solaris OS, took this opportunity to upgrade
from Solaris 8 to Solaris 9, installed all of the Solaris 9 patches, and
finally got dhcp running again on the re-built server.  This is when the
pings started going to all the computers on site and not just the dhcp
server.  As a last resort to stop the hacking I blocked ping to all of
our computers.  Blocking ping stopped all the hacking packets at the
router firewall, they are no longer getting into our network.  The
hacker traffic to the router is slowing down our legitimate WAN traffic
and now that the access list on the router is much longer this also
slows down legitimate network traffic which has to be compared to the
access list.
- I ran into the same problem that Shannon experienced back in April or
May.  I used the new Solaris Management software to add a user to a
group in the NIS+ tables and it messed up the NIS+ tables and the
ownership of all the files in the home directories for every user.  It
took me three days to correct everything in the NIS+ tables and the
files.
- Last Friday night the network to Caltech went down causing us to loose
our DNS servers.  I modified all our local DNS tables to use the DNS
servers at MIT.  At Larry's suggestion I'm looking into building our own
secondary DNS server.
 

CIT:
(Mike)
-Ghosted Cindy Akutagawa and Calum Torrie's computer.
-Updated all NTSRV's this week with windows update and Norton anti-virus. I
also check the security logs for intrusions.
-Setup a user account for a visitor that is working with Hiro.
-Worked on a hardware problem for Mike Smith. This PC was having a problem
with the CDROM I was able to correct this problem. He is back up and running.
-Reloaded Calum Torrie's engineering workstation. This computer had a bad
hard disk. I tried to perform a mirror image of the damaged drive to a new
hard disk, by using multiple restore utilities that were suppose to handle
these types of problems. This got me know where, but I was able to get most
of this users data off the old drive and transfer over to the new drive.
This is a big project due to reloading OS, GC software and multiple
engineering software packages that needed to be loaded. There was a problem
logging into solid works to download the latest service packs, due to some
licensing issues that required many phone calls to solid works tech
support. This issue is now resolve!
-Worked with Cindy Akutagawa showing her how to work with and get the best
performance out of her new scanner.
-Worked on a virus problem that was on Gina Salone's computer. I ended up
having to download and run a removal tool for this virus, cleanup registry,
update windows and virus scan software. Plus I loaded zone alarm to prevent
this from happening again. This bug also corrupted her e-mail, which needed
to be un-installed and re-installed. It is possible that this computer
might have to be reloaded from scratch, due to this computer having a few
more glitches that are still present.
-Burned end of the month NTSRV's ghost images to DVD.
-Started going through and updating some of our loaner laptops, that
were brought back from travel. This includes updating installed software,
and most installed virus scan software and windows updates and cleaning up
the users old data that was left on these computers.
-Called in Linda Turner's old Dell laptop. The LCD went out on this laptop
and had to go through multiple diagnostic tests with Dell's tech support
people. After being on the phone with these for a few hours they decided to
send me out a tech to replace the LCD.
 

(Lisa)
- Updated the mail code on acrux. Spent some time talking to the developer of
the pop code we use regarding a problem with webmail and pop.  I know why there
was a problem but have not yet recompiled the code.
- Reconfigured the web server on lsc1 to accommodate the stochastic website.
- Installed castor in the server room.  It is a special use web server.
- Spent many hours demo'ing the next generation of wireless access points.
There are some management issues with the new models that will take me some time
to resolve.
- Got a quote for the update the webmail software.
 

(Veronica)
- LSC website: Finished scripting and images for the upcoming meeting
website. After some troubleshooting, installed the website at the LSC
webserver. Posting updates as they arrive almost hourly.
Worked with Kaice Reilly on migrating the website for the stochastic group
to the LSC webserver. This involved working out some server configuration
issues.
- LIGO website: Set up and monitored the VRVS videoconferencing for the
last seminar. Working with Larry and Mike on bulletproofing the system;
we were testing a combined VNC-VRVS setting to allow more detailed view of
the viewgraphs, which is sometimes difficult with the current setup. So
far, the desktop sharing system that VRVS offers seems to be an
alternative.
Briefly worked with George Stokes regarding updates of the DCC
architecture. We need to meet and discuss his proposed changes in more
detail.
Posted various updates to the LIGO website, doing several document
transfers and conversions in the process. Provided user support.
- CaJAGWR: Videotaped the opening talk by Massimo Tinto; captured and
compressed the video, which is ready to be transferred to the streaming
media server and posted online. Provided user support.
- Project Science website: Posted the bulk of the presentations from the
last workshop. Converted them to pdf. Updating the database of attendees
and generating an e-mail distribution list.
 

(Larry)
-Worked a number s/w licensing issues. The Ansys pkg has been renewed for
another year. We still have a few pkgs. that need to get the new licensing
worked out.
Purchased a number of supply items for different people.
-Assisted the DCC with a number of document issues. Most just getting files
put into the correct locations.
-Worked with the Observatories on a variety of items. The majority of the time
was spent with the Livingston site. The WAN has been a hot topic and then
assistance with their recovery from a major server crash.
-Spent time working on PC's. All were minor issues with one exception where
reloading a couple of pkgs. from scratch was needed.
-Worked a number of user and account issues.
-Continue rewriting a number of documents.
 

(Sears)
 

* (BS) Systems Work:                                    (1.0 days)
       - Ilog upgrade to disable some link features which affect privacy.
       - Created new Caltech site Ilog group and added users.
