TODO

EMAILING ALL THE USERS https://wiki.cs.earlham.edu/index.php/Sysadmin:Old:Contacting_All_Users
SHUTDOWN SCHEDULED FOR SUNDAY (APRIL 16)
- Check/update instructions - one version is at https://wiki.cs.earlham.edu/index.php/Sysadmin:ImportantInfo:PowerFailure, there are others too
- Notify users
Fix certs for gitlab, etc.
Secure 1-2 admins for the summer
Prep layout for May-June usage
Practice shutdown-startup procedure (with Michael)
Nsswitch consistency across all machines
Document tools: startup / shutdown - Charlie
Use Sysadmin namespace for all our pages - All
- Testing usefulness of documentation - Dave
Al Salam: configure switch, re-rack. - Vitalii
- HP switch should be reset and tested.
LDAP cleanup of system users / old groups - James
Layout - Nirdesh
- Lo0 RAID (mdadm)
- 10GB from Dali to lo0 (adding rules on compute node routing tables as a possible fix)
- BIOS reset
10Gb, perfsonar, ...
Monitoring: (Ganglia, Shinken)
- Getting consistency among all the machines(check_nrpe regularly stops working).
Whedon: configured and available
Change passwords (on everything). Postgres, shenken, ...
Webcam on office whiteboard (new office location?)
Learn virtual machine architecture and modules - Dave
- Document in a format for future admin training?
- Find existing introduction material
Mirror control for testing, swapping, etc.

DONE (19 Jan 2017)

Examine extra "layout" node. - Adam
- Differences are: Single PSU, Single GPGPU, No VGA.
- It has Infiniband and 10GB cards installed.
Networking - Adam, Charlie
- IP over Infiniband working on layout
  - Resolved by resetting IB switch configuration: ibwarn: [3349] mad_rpc_rmpp: _do_madrpc failed; dport (Lid 1)

FUTURE

-After creating your own 3D model follow this steps:
-* Render and compile your code by pressing F6
-* Export the design as .stl
-* If the file is in your own computer, move the file(name.stl) to the Mac found in Turing lab(CST 222)
-=== '''Overhang / Supports''' ===
-Software: Meshmixer
-Once you import a pre-existing model:
+<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>
-* Use the align tool under the Edit tab to place model on bed
-* Use the overhang tool under the Analysis tab to generate supports for the model
-* Export as " *.stl " when finished
-=== '''Instructions on how to use the 3D printers:''' ===
-==== '''Robo R1+ 3D Printer''' ====
-Software for the printer: MatterControl
-Printing from an SD card:
-*Insert a microSD card into the Mac and get rid of any files in it.
-*Open MatterControl and drag your .stl file into the QUEUE section of the application.
-*On the top-left section, click on “Select Printer.” Select “Robo 3D TM Turing” in the window that pops out.
-*Towards the bottom of the QUEUE section, you will find a “Queue” button. Click on it to get a list.
-*On the list, below GCode, select “Export to Folder or SD Card.” Click on the microSD card under “Devices” in the side panel and click on “Export”
-*Now, in Finder, browse to the microSD card and rename the file you just exported as “auto0.g” (auto zero dot g). Choose “Use.g” if a prompt appears.
-*Then, safely remove the microSD card from the Mac and insert it into the Robo 3D printer.
-*Prep the build plate using one the following:
-**Glue Stick
-**Vinyl Sheeting
-**Hairspray
-:Apply whichever product on the surface of the build plate enough to cover the surface you will be printing on.
-*Turn the printer on. Your print will start after about 5 minutes.
-*After the print is over, wait for the temperature to cool down and carefully remove the 3D printed object from the build plate.
-*Clean the build plate.
-Printing from the computer:
-*Open MatterControl and drag your .stl file into the QUEUE section of the application.
-*On the top-left section, click on “Select Printer.” Select “Robo 3D TM Turing” in the window that pops out.
-*Under "Settings" ensure that the correct material is selected.
-*Under "Controls" an offset of 0.9 typically shows the best results.
-*Pre-heat the extruder and bed on the same page.
-*Alternatively, near the top center of the screen, an extruder temperature and a bed temperature will be shown, mouse over and click "pre-heat" for both.
-*Prep the build plate using one the following:
-**Glue Stick
-**Vinyl Sheeting
-**Hairspray
-*Click print once the printer has heated up.
-*After the print is over, wait for the temperature to cool down and carefully remove the 3D printed object from the build plate.
-*Clean the build plate.
-==== '''Taz Lulzbot 3D Printer''' ====
-Software for the printer: Cura
-Steps to follow in order to print:
-*Insert a microSD card into the Mac.
-*Open Cura and press “Load Model” to upload the stl file you want to print.
-*Right click “Control” and select the “Save gcode” and then choose the SDcard under the “Devices” panel.
-*Make sure the Taz 3D Printer is turned on.
-*Safely eject the sdCard from the Mac and insert it into Taz Printer (on left side of the LCD screen)
-**Make sure the SD card has the pins facing towards you when insert it
-*Back on the LCD screen, rotate the knob counter-clockwise to decrease the print speed to ~50%
-*Press the knob, scroll down by rotating the knob clockwise and select “Temperature”.
-*Select “Custom Temp” and set the "Nozzle" to 240 and "Bed" to 64
-*After a few seconds, the LCD will display the info screen again and the printer will start heating up. Wait until the temperatures reach 240C and 64C.
-*In the info screen, press the knob again. Scroll down and select “Print from SD” Select your file and it will start printing right away.
-*Once the printing has finished, wait for the bed to cool down and carefully remove the 3D printed object.
-==== '''MakerBot 3D Printer''' ====
-Software for the printer: ReplicatorG
-Steps to follow in order to print:
-*Insert a microSD card into the Mac.
-*Open ReplicatorG, drag and drop your stl file into application screen.
-*Adjust your model if you need to.
+== Switches ==
-*Select “Generate GCode” on the bottom right.
-*Make sure the values are set as shown in the image below and then select “Generate GCode”
-:[[File:Replicator_values.png|thumb|250px|center]]
-*If prompted with an “Acceleration Warning” select “OK”
+{| style="float:left; margin-right:2px;"
-*Wait until it generates the gcode.

+=== TODO ===
+* EMAILING ALL THE USERS https://wiki.cs.earlham.edu/index.php/Sysadmin:Old:Contacting_All_Users
+* SHUTDOWN SCHEDULED FOR SUNDAY (APRIL 16)
+** Check/update instructions - one version is at https://wiki.cs.earlham.edu/index.php/Sysadmin:ImportantInfo:PowerFailure, there are others too
+** Notify users
+* Fix certs for gitlab, etc.
+* Secure 1-2 admins for the summer
+* Prep layout for May-June usage
+* Practice shutdown-startup procedure (with Michael)
+* Nsswitch consistency across all machines
+* Document tools: startup / shutdown - Charlie
+* Use Sysadmin namespace for all our pages - All
+** Testing usefulness of documentation - Dave
+* Al Salam: configure switch, re-rack. - Vitalii
+** HP switch should be reset and tested.
+* LDAP cleanup of system users / old groups - James
+* Layout - Nirdesh
+** Lo0 RAID (mdadm)
+** 10GB from Dali to lo0 (adding rules on compute node routing tables as a possible fix)
+** BIOS reset
+* 10Gb, perfsonar, ...
+* Monitoring: (Ganglia, Shinken)
+** Getting consistency among all the machines(check_nrpe regularly stops working).
+* Whedon: configured and available

+=== DONE (19 Jan 2017) ===
+* Examine extra "layout" node. - Adam
+** Differences are: Single PSU, Single GPGPU, No VGA.
+** It has Infiniband and 10GB cards installed.
+* Networking - Adam, Charlie
+** IP over Infiniband working on layout
+*** Resolved by resetting IB switch configuration: <code>ibwarn: [3349] mad_rpc_rmpp: _do_madrpc failed; dport (Lid 1)</code>
