At Fusion 2018 we ran a two camera setup for recording only. With the flight cases for room 1 and room 2 came two tallycoms whose config differed from their label and whose config was inconsistent.

Getting voctolight on both tallycoms to (manually) work took unnecessarily much time. It boils down to being new to the matter, wrong labels, wrong config and different behavior after correcting the config, due to different base OS versions (https://www.raspberrypi.org/forums/viewtopic.php?t=187225).

Below is written from scratch, so that someone who brings their (linux) laptop and never worked with the VOC before, has a good starting point. This section can be moved to a separate page in true wiki fashion.

1. Ensure that you have access to this wiki. If you haven't, you can't read this. :brainexplosion: - Download + unzip the latest Raspbian lite - https://downloads.raspberrypi.org/raspbian_latest (at the time of writing April 2018)
   WARNING: 350 MB - A lot in case of shitty/shared uplink… <code> user@laptop$ cd ~/Downloads user@laptop$ wget http://director.downloads.raspberrypi.org/raspbian_lite/images/raspbian_lite-2018-04-19/2018-04-18-raspbian-stretch-lite.zip </code> - Unpack and write the Raspbian image to a microSD card (replace /dev/sdX with the correct device name)
   More details here: https://www.raspberrypi.org/documentation/installation/installing-images/linux.md <code> user@laptop$ cd ~/Downloads user@laptop$ unzip -p 2018-04-18-raspbian-stretch-lite.zip | sudo dd of=/dev/sdX bs=4M conv=fsync </code>

   == 2. Setup ansible + VOC cm repo == - Install ansible and git <code> user@laptop$ sudo {dnf,yum,apt-get} install ansible git </code> - Clone the VOC cm repo <code> user@laptop$ mkdir -p ~/Documents/voc/ user@laptop$ cd ~/Documents/voc/ user@laptop$ git clone https://github.com/voc/cm.git </code>

   == 3. Final ansible run == - Run on multiple tallycoms - WARNING: placeholder only <code> user@laptop$ cd ~/Documents/voc/cm/ user@laptop$ ./ansible-playbook-keepass -u voc –ask-pass –become –become-method=sudo –ask-become-pass \ -i event -t tally \ -l 10.73.1.15,10.73.1.16,10.73.2.15,10.73.2.16,10.73.3.16,10.73.4.15,10.73.4.16 \ -t tally \ tally-pis.yml </code>
