Now have got Network UPS Tools (NUT) working for UPS in the ctalab
- This will shutdown the server automatically in the event of a power outage, and notify me, Bill, and Massimo

Brief summary of what was done:

Mostly followed directions from here: https://kinavu.org/install-and-configure-nut-on-ubuntu/

sudo apt install nut
Add to files in /etc/nut/
- ups.conf
  - [nevis-ctalab-ups]
    driver = snmp-ups
    port = nevis-ctalab-ups.nevis.columbia.edu
    community = public
    mibs=apcc
- upsd.users
  - [monups]
    password = acdc
    upsmon master
- upsmon.conf
  - MONITOR nevis-ctalab-ups@localhost 1 monups acdc master
    NOTIFYCMD /home/bin/notify.sh
- nut.conf (this addition was done later in the process, may have been the cause of failures [previously MODE=none])
  - MODE=standalone
Created file /home/bin/notify.sh and made it executable
- echo "$*" | /bin/mail -s "upsmon on ${HOSTNAME}" sysadmin@nevis.columbia.edu ca2762@columbia.edu capasso@nevis.columbia.edu
did sudo cp /lib/udev/rules.d/62-nut-usbups.rules /etc/udev/rules.d/ and followed it with a reboot
/var/run/nut already existed, so did:
- sudo chown root:nut /var/run/nut
- sudo chmod 770 /var/run/nut
- Not sure if either of these were necessary
[TESTING COMMANDS] The upsdrvctl stuff that was being used in the tutorial was having issues, so I just tried out what Bill shared which was:
- sudo systemctl enable nut-server
  sudo systemctl enable nut-monitor
  sudo systemctl start nut-server
  sudo systemctl start nut-monitor
- and then: sudo upsc nevis-ctalab-ups to see if it was working
The first time I ran the testing commands, there wasn't a whole lot of output, except with the start nut-monitor I got out:
- Job for nut-monitor.service failed because the service did not take the steps required by its unit configuration.
  See "systemctl status nut-monitor.service" and "journalctl -xe" for details.

So I ran systemctl status nut-monitor.service and it told me:

o nut-monitor.service - Network UPS Tools - power device monitor and shutdown controller
Loaded: loaded (/lib/systemd/system/nut-monitor.service; enabled; vendor preset: enabled)
Active: failed (Result: protocol) since Tue 2020-12-29 16:12:07 EST; 10s ago

Dec 29 16:12:07 ctalab-Precision-3630-Tower upsmon[2734]: Then set MODE to a suitable value in /etc/nut/nut.conf to enable it
Dec 29 16:12:07 ctalab-Precision-3630-Tower systemd[1]: nut-monitor.service: Can't open PID file /var/run/nut/upsmon.pid (yet?) after start: No such file or directory
Dec 29 16:12:07 ctalab-Precision-3630-Tower systemd[1]: nut-monitor.service: Failed with result 'protocol'.
Dec 29 16:12:07 ctalab-Precision-3630-Tower systemd[1]: Failed to start Network UPS Tools - power device monitor and shutdown controller.

Following this, I:
- Installed the server with sudo apt install nut-snmp
- Changed in the nut.conf file: MODE=none -> MODE=standalone
- Rebooted again

This seemed to work, full output:

(base) ctalab@ctalab-Precision-3630-Tower:~$ sudo systemctl enable nut-server
Synchronizing state of nut-server.service with [[SysV][SysV]] service script with /lib/systemd/systemd-sysv-install.

NMC for UPS now working
- Will adjust the details of the networking section of the NevisLabsSetup page to reflect additional changes

Setting up all the networking and devices
- ctalab machine
  - # host odo
    odo.nevis.columbia.edu is an alias for ctalab.nevis.columbia.edu.
    ctalab.nevis.columbia.edu has address 10.44.2.10
  - Started ssh server following direction on this page:
    - https://linuxize.com/post/how-to-enable-ssh-on-ubuntu-18-04/
- Smart UPS
  - # host nevis-ctalab-ups
    nevis-ctalab-ups.nevis.columbia.edu has address 10.44.1.204
  - account: admin
    password: ctaups
  - NOT WORKING CURRENTLY
Switched capacitors on test board to power Hamamatsu SiPM (Nancy)
- Did this to accommodate higher bias voltage needed
- C1, C3, C4: replace with 100nF, 100V (1206 package)
- C5, C6, C7: replace with 2.2uF, 100V (1206 package)

Tried to find the network card for the UPS
- Not located upstairs in the supply room as was initially thought
- Found one that looked like it could be it in Bill's office, but not sure how it could've gotten there with Bill absent
Programmed the Aim TTi EL302P -USB PSU
- added as a class of the dcps python package, new class called 'AimTTiEL302P"
- can find the code at /home/ctalab/anaconda3/envs/cta/lib/python3.8/site-packages/dcps/AimTTiEL302P.py
  - So far implemented commands to do:
    - Write voltage
      - setVoltage(self, voltage)
    - Write current
      - setCurrent(self, current)
    - Read the set voltage
      - queryVoltage(self)
    - Read the set current
      - queryCurrent(self)
    - Measure voltage
      - measureVoltage(self)
    - Measure current
      - measureCurrent(self)
    - Turning output on/off
      - outputOff(self)
      - outputOn(self)
    - Checking if output is on
      - isOutputOn(self)
  - Start-up code is:
    - from dcps import AimTTiEL302P
    - aim = AimTTiEL302P ('ASRL/dev/ttyACM0::INSTR')
    - aim.open()
  - and then use the `aim` object to do all the commands
- Still need to implement commands for
  - switching between local/remote (this isn't an option for the model we have)
