josephb | Update | Computers | Y end simulated plant progress |
Currently, the y end plant is yep.mdl. In order to compile it properly (for the moment at least) requires running the normal makefile, then commenting out the line in the makefile which does the parsing of the mdl, and rerunning after modifying the /cds/advLigo/src/fe/yep/yep.c file.
The modifications to the yep.c file are to change the six lines that look like:
"plant_mux[0] = plant_gndx" into lines that look like "plant_mux[0] = plant_delayx". You also have to add initialization of the plant_delayx type variables to zero in the if(feInt) section, near where plant_gndx is set to zero.
This is necessary to get the position feedback within the plant model to work properly.
#NOTE by Koji
CAUTION:
This entry means that Makefile was modified not to parse the mdl file.
This affects making any of the models on megatron. |

To prevent this confusion in the future, at Koji's suggestion I've created a Makefile.no_parse_mdl in /home/controls/cds/advLIGO on megatron. The normal makefile is the original one (with correct parsing now). So the correct procedure is:
1) "make yep"
2) Modify yep.c code
3) "make -f Makefile.no_parse_mdl yep" |

josephb | Configuration | Computers | yum update fixed on control room machines |
I went to Ottavia, and tried running yum update. It was having dependancy issues with mjpegtools, which was a rpmforge provided package. In order to get it to update, I moved the rpmforge priority above (a lower number) that of epel ( epel -> 20 from 10, rpmforge -> 10 to 20). This resolved the problem and the updates proceeded (all 434 of them). yum update on Ottavia now reports nothing needs to be done.
I went to Rosalba and found rpmfusion repositories enabled. The only one of the 3 repositories in each file enabled was the first one.
I then added priority listing to all the repositories on Rosalba. I set CentOS-Base and related to priority=1. I set CentOS-Media.repo priority to 1 (although it is disabled - just to head off future problems). I set all epel related to priorities to 20. I set all rpmforge related priorities to 10. I set all rpmfusion related priorities to 30, and left the first repo in rpmfusion-free-updates and rpmfusion-nonfree-updates were enabled. All other rpmfusion testing repositories were disabled by me.
I then had to by hand downgrade expat to expat-1.95.8-8.3.el5_4.2.x86_64 (the rpmforge version). I also removed and reinstalled x264.x86_64. Lastly I removed and reinstalled lyx. yum update was then run and completed successfully.
I installed yum-priorities on Allegra and made all CentOS-Base repositories priority 1. I similarly made the still disabled CentOS-Media priority 1. I made all epel related repos priority 20. I made all lscsoft repos priority=50 (not sure why its on Allegra and none of the other ones). I made all rpmforge priorities 10. I then ran "yum update" which updated 416 packages.
So basically all the Centos control room machines are now using the following order for repositories:
CentOS-Base > rpmforge > epel > (rpmfusion - rosalba only) > lscsoft (allegra only)
I'm not sure if rpmfusion and lscsoft are necessary, but I've left them for now. This should mean "yum update" will have far fewer problems in the future.

josephb | Update | Computers | Updated bitwise.pm in RCG SVN plus other fixes |
To fix a problem one of the models was having, I checked the CVS version of the Bitwise.pm file into the SVN (located in /home/controls/cds/advLigoRTS/src/epics/util/lib), which adds left and right bit shifting funtionality. The yec model now builds with the SVN checkout.
Also while trying to get things to work, I discovered the cdsRfmIO piece (used to read and write to the RFM card) now only accepts 8 bit offsets. This means we're going to have to change virtually all of the RFM memory locations for the various channels, rather than using the values from its previous incarnation, since most were 4 bit numbers. It also means it going to eat up roughly twice as much space, as far as I can tell.
Turns out the problem we were having getting to compile was nicely answered by Koji's elog post. The shmem_daq value was not set to be equal to 1. This caused it to look for myrimnet header files which did not exist, and caused compile time errors. The model now compiles on megatron.
[Edit by KA: 4 bit and 8 bit would mean "bytes". I don't recall which e-log of mine Joe is referring.]

josephb | Update | Computers | Ottavia has moved |
Ottavia was moved this afternoon from the control room into the lab, adjacent to Mafalda in 1Y3 on the top shelf. It has been connected to the camera hub, as well as the normal network. Its cables are clearly labeled. Note the camera hub cable should be plugged into the lower ethernet port. Brief tests indicate everything is connected and it can talk to the control room machines.
The space where Ottavia used to be is now temporarily available as a good place to setup a laptop, as there is keyboard, mouse, and an extra monitor available. Hopefully this space may be filled in with a new workstation in the near future. |

This is a reminder (mainly for Steve, who somehow doesn't believe these things) that op540m is not to be used for your general pleasure.
No web, no dataviewer, no DTT. Using these things often makes the graphical X-Windows crash. I have had to restart the StripTool, our seismic BLRMS and our Alarms many times because someone uses op540m, makes it crash, and then does not restart the processes.
Stop breaking op540m, Steve! |

josephb | Summary | Computers | Removed scaling fonts from medm on Allegra |
Because it was driving me crazy while working on the new medm screens for the simulated plant, I went and removed the aliased font entries in /usr/share/X11/fonts/misc/fonts.alias that are associated with medm. Specifically I removed the lines starting with widgetDM_. I made a backup in the same directory called fonts.alias.bak with the old lines.
Medm now behaves the same on op440m, rosalba, and allegra - i.e. it can't find the widgetDM_ scalable fonts and defaults to a legible fixed font. |

josephb | Summary | Computers | 40m computer security issue from last night and this morning |
The following is not 100% accurate, but represents my understanding of the events currently. I'm trying to get a full description from Christian and will hopefully be able to update this information later today.
Last night around 7:30 pm, Caltech detected evidence of computer virus located behind a linksys router with mac address matching our NAT router, and at the IP 131.215.114.177. We did not initially recognize the mac address as the routers because the labeled mac address was off by a digit, so we were looking for another old router for awhile. In addition, pings to 131.215.114.177 were not working from inside or outside of the martian network, but the router was clearly working.
However, about 5 minutes after Christian and Mike left, I found I could ping the address. When I placed the address into a web browser, the address brought us to the control interface for our NAT router (but only from the martian side, from the outside world it wasn't possible to reach it).
They turned logging on the router (which had been off by default) and started monitoring the traffic for a short time. Some unusual IP addresses showed up, and Mike said something about someone trying to IP spoof warning coming up. Something about a file sharing port showing up was briefly mentioned as well.
The outside IP address was changed to 131.215.115.189 and dhcp which apparently was on, was turned off. The password was changed and is in the usual place we keep router passwords.
Update: Christian said Mike has written up a security report and that he'll talk to him tomorrow and forward the relevant information to me. He notes there is possibly an infected laptop/workstation still at large. This could also be a personal laptop that was accidently connected to the martian network. Since it was found to be set to dhcp, its possible a laptop was connected to the wrong side and the user might not have realized this.

We rebooted c1iovme, c1susvme1, and c1susvme2 during lunch. Frank is going to write a thrilling elog about why c1iovme needed some attention.
C1susvme 1&2 have had their overflow numbers on the DAQ_RFMnetwork screen red at 16384 for the past few days. While we were booting computers anyway, we booted the suses. Unfortunately, they're still red. I'm too hungry right now to deal with it....more to follow. |

Jenne | Update | Computers | Some channels not being recorded!!! |
[Rana, Jenne]
We discovered to our great dismay that several important channels (namely C1:IOO-MC_L, but also everything on c1susvme2) are not being recorded, and haven't been since May 17th. This corresponds to the same day that some other upgrade computers were installed. Coincidence?
We've rebooted pretty much every FE computer and the FrameBuilder and DAQ_CONTROL approximately 18 times each (plus or minus some number). No matter what we do, or what channels we comment out of the C1SUS2.ini file, we get a Status on the DAQ_Detail screen for c1susvme2 of 0x1000. Except sometimes it is 0x2000. Anyhow, it's bad, and we can't make it good again.
I have emailed Joe about fixing this (with some assistance from Alberto, since we all know how much he likes doing the Nuclear Reboot option for the computers :) |

josephb | Update | Computers | Some channels not being recorded!!! |
This has been fixed, thanks to some help from Alex. It doesn't correspond to new computers being put in, but rather corresponds to a dcu_id change I had made in the new LSC model.
The fundamental problem is way back when I built the new LSC model using "lsc" as the name instead of something like "tst", I forgot to go to the current frame builder master file (/cvs/cds/caltech/chans/daq/master) and comment out the C1LSC.ini line. Initially there was no conflict with c1susvme, because the initially was dcu_id 13. The dcu_id was eventually changed to 10 from 13 , and thats when it conflicted with the c1susvme2 dcu_id which was also 10. I checked it against wiki edits to my dcu_id list page and I apparently updated the list on May 20th when it changed from 13 to 10, so the time frame fits. Apparently it was previously conflicting with C0GDS.ini or C1EXC.ini, which both seem to have dcu_id = 13 set, although the C1EXC file is all commented out. The C0GDS.ini file seems to be LSC and ASC test points only.
The solution was to comment out the C1LSC.ini file line in the /cvs/cds/caltech/chans/daq/master file and restart the framebuilder with the fixed file.

Just as I expected, since these hunuman didn't actually check MC_L after doing this stuff, MC_L was only recording ZERO. Joe and I reset and restarted c1susmve2 and then
verified (for real this time) that the channel was visible in both the Dataviewer real time display as well as in the trend.

The lesson here is that you NEVER trust that the problem has been fixed until you check for yourself. Also, we must always
specify a very precise test that must be used when we ask for help debugging some complicated software problem.

josephb | Update | Computers | Fb40m and a few other machines turned off briefly just before 11am |
I turned off fb40m2 and fb40m temporarily while we added an extra power strip to the (new) 1X6 rack at the bottom in the back. This is to allow for the addition of the 4600 computer given to us by Rolf (which needs a good name) into the rack above the fb machine. The fb40m2 was unfortunately plugged into the main power connectors, so we unplugged two of its cables, and put them into the new strip. While trying to undo some of the rats nest of cables in the back I also powered down and unpluged briefly the c0dcu1, the pem crate, and the myrinet bypass box.
I am in the process of bringing those machines back up and restoring the network.
Also this morning, Megatron was moved from the end station into the (new) 1X3 rack, along with its router. This is to allow for the installation of the new end computer and IO chassis.

josephb | Update | Computers | Added channel to ADCU_PEM (C0DCU1) |
I modified the C1ADCU_PEM.ini file in /cvs/cds/caltech/chans/daq/ (after making a backup), and added a temporary channel called C1:PEM-TEMP_9, the 9 corresponding to the labeled 9 channel on the front of the BNC breakout in the 1Y7 rack. The chnnum it was set to is 15008 (it was commented out and called C1:PEM-PETER_FE). I also set the data rate to 2048.
I then did telnet fb40m 8087, and shutdown, and also hit the blue reconfig button on the DAQ status screen for the C0DCU1 machine. The framebuilder came back up. I confirmed the temporary channel, as well as the Guralp channels were still working from C0DCU1.
We have strung a cable in the cable trays from the SP table to the 1Y7 rack, which has been labeled as "Phasecam PD". This will be used to record the output of an additional photodiode.

josephb,kiwamu | Update | Computers | New X end FE and IO chassis work |
We finished setting up the new X end front end machine (still temporarily called c1scx), and attached it to its IO chassis. We're preparing for a test tomorrow, where we redirect the Limo breakout box to the new front end and IO chassis, so Kiwamu can test getting some green locking channels into his controls model.
We strung a pair of blue fibers from the timing master to the new X end (and labeled them), so we have a timing signal for the IO chassis. I also labeled the orange fiber Alex had repurposed from the RFM to timing for the new Y end when I noticed he had not actually labelled it at the timing master. |

josephb | Update | Computers | Possible solution for the last ADC |
After talking with Jenne, I realized the ADC card in the c1ass machine was currently going unused. As we are short an ADC card, a possible solution is to press that card into service. Unfortunately, its currently on a PMC to PCI adapter, rather than PMC to PCIe adapter. The two options I have are to try to find a different adapter board (I was handed 3 for RFM cards, so its possible there's another spare over in downs - unfortunately I missed Jay when I went over at 2:30 to check). The other option is put it directly into a computer, the only option being megatron, as the other machines don't have full length PCI slot.
I'm still waiting to hear back from Alex (who is in Germany for the next 10 days) whether I can connect both in the computer as well as with the IO chassis.
So to that end, I briefly turned off the c1ass machine, and pulled the card. I then turned it back on, restarted all the code as per the wiki instructions, and had Jenne go over how it looked with me, to make sure everything was ok.
There is something odd with some of the channels reading 1e20 from the RFM network. I believe this is related to those particular channels not being refreshed by their source (which is other suspension front end machines), so its just sitting at a default until the channel value actually changes.

Today I noticed that the FE SYNC counters of c1susvme1/2 on the RFM network screen were stuck at 16384. I tried to reboot the machines to fix the problem but it didn't work.
The BS watchdog tripped off when I did that, because I had forgotten to disable it. I had to wait for a few minutes before it settled down again.
Later I also re-locked the mode cleaner. But before I could do it, Rana had to reduce the MC_L offset for me. |

josephb, kiwamu | Update | Computers | Megatron temporarily disconnected, c1iscex firewalled, green FE test |
We are moving towards a first test of getting Kiwamu's green locking signals into the new front end at the new X end, as well as sending signal out to the green laser temperature control.
Towards that end, we borrowed the router which we were using as a firewall for megatron. At the moment, megatron is not connected to the network. The router (a linksys N wire router), was moved to the new X end, and setup to act as a firewall for the c1iscex machine.
At this point, we need to figure which channels of the DAC correspond to which outputs of the anti-imaging board (D000186) and coil driver outputs. Ideally, we'd like to simply take a spare output from that board and bring it to the laser temperature control. The watchdogs will be disabled when testing to avoid any unfortunate mis-sent signals to the coils. It looks like it should be something like channels 6,7,8 are free, although I'm not positive if thats the correct mapping or if there's a n*8 + 6,7,8 mapping.
The ADC should be much easier to determine, since we only have a single 16 channel set coming from the lemo breakout box. Once we've determined channels, we should be all set to do a test with the green system. |

1 yum remove python-numpy
2 yum install python-matplotlib numpy scipy --enablerepo=epel --disablerepo=rpmforge
This is all to support the LIGO data listener which now has a shortcut on rosalba and allegra's desktop. It seems to work for (live mode) right now.

Jenne | Omnistructure | Computers | op540m dead |
I think op540m has finally bitten the dust. I noticed that both of its screens were black, so I assumed that it had crashed due to known graphics card issues or something. But upon closer inspection, it is way more dead than that. I checked that it does have power (at least the power cable is securely plugged in at both ends, and the power strip its on is successfully powering several other computers), but I can't make any lights or anything come on by pressing the power button on the front of the computer tower.
Immediate consequences of op540 not being operational are the lack of DMT, and the lack of Alarms.
Joe is doing an autopsy right now to see if its really dead, or only 'mostly dead'.
EDIT: Joe says maybe it's the power supply for the computer. But he can't turn it on either. |

- in the GRUB screen edit the boot command by pressing the appropriate key listed in the screen
- in the boot command-line put " single" in the end (no other change is normally needed), don't save
- press ENTER and the system will reboot to a root shell (# prompt)
- cd /root
- run the NVIDIA driver script
- exit the shell (ctrl-d), let the system reboot
- it should flash (mostly green) "nvidia" screen before starting X
- in case of problems run system-config-display and revert to vesa driver
- login as "root" and run "nvidia-settings" from command line or GUI menu to add/configure display

Why are we running CentOS 4.8 instead of 5.5 ? What runs at LLO? What runs in Downs? |

At LLO the machines are running Centos 5.5. A quick login confirms this. Specifically the release is 2.6.18-194.3.1.el5.

* rossa needs to be able move windows between monitors: Xinerama?
* there are permissions problems: controls on rossa can't
make and delete directories made by 'controls' elsewhere.
Some sort of user# or group issue? |

Alberto | Configuration | Computers | Netgear Network Switch fan broken. |
The Netgear Network Switch in the top shelf of Nodus' rack has a broken fan. It is the one interfaced to the Martian network.
The fan must have broken and it is has now started to produce a loud noise. It's like a truck was parked in the room with the engine running.
Also the other network switch, just below the Netgear, has one of its two fans broken. It is the one interfaced with the General Computer Side.
I tried to knock them to make the noise stop, but nothing happened.
We should consider trying to fix them. Although that would mean disconnecting all the computers. |

The controls group is user id 500 by default on most new machines. Unfortunately, the user ID used across the already existing machines is 1001. One method of doing this switch is in this elog. You can also do the change of the controls ID by becoming root and using the graphical command system-config-users. This will let you change the user ID and group ID for controls to 1001. This graphical interface also lets you change the login shell.
Unfortunately, I had some minor difficulty and I ended up removing the old controls and creating a new controls account with the correct values and using tcsh. The .cshrc file has been recreated to source cshrc.40m. The controls account now has correct permissions, although some of the preferences such as background will need to be reset.

Alberto | Configuration | Computers | Nodus connection not working. Fixed |
[Joe, Alberto]
The Nodus connection to the Martian network stopped working after someone switched cables on the Netgear router. Apparently that router doesn't like to have the 23 and 24 ports connected at the same time.
Joe fixed the connection just freeing either the 23 or the 24 port. |

sanjit | Configuration | Computers | aldabella network configuration |
added name server 192.169.113.20 as the first entry in /etc/resolv.conf
changed the host IPs in /etc/hosts to 192.168.xxx.yyy
made:
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhos6
as the first two lines of /etc/hosts
/cvs/cds mounts
on ethernet, DNS look-up works without the explicit host definitions in /etc/hosts,
but those entries are needed for wifi only connection.

I wiped out the old CentOS install on rossa and installed CentOS 5.5 on there. The DVDs are on a spindle in the control room; there were 2 iso's, but I only needed the first to install most things.
It still needs to get all of the usual stuff (java, flash, nvidia) installed as well as setting up the .cshrc and the NFS mount of /cvs/cds. The userID and groupID are set to 1001 as before. Whoever
sees Sanjit first should steer him towards this elog entry.

I found Sanjit's instructions for doing the Nvidia settings too complicated and so I followed these instructions from Facebook:
http://www.facebook.com/notes/centos-howtos/installing-nvidia-display-drivers-on-centos-55/399295987425
After installations, the monitors were autodetected and the Xinerama effect is working. |
