First Release: October 2020 (QR)

Step 1: Connect to machine over SSH using PuTTY or Terminal


  1. Establish a command line session over SSH.

    • Windows PC: you will need to install an SSH client. We recommend PuTTY.

      • Once PuTTY is installed and launched, we'll just need to input the IP address ( if connecting over USB) to the Host Name field, everything else can be left default.

  • Macs: this can be done with the default MacOS Terminal

    • Open a Terminal window and enter ssh pocketnc@

    • You will be prompted for a password, which is pocketnc

Step 2: Create Missing Directories


  1. Copy and paste the below command into terminal and hit enter (make sure there is no trailing whitespace after the "done":

for i in {0..7}; do sudo mkdir -p "/media/usb$i"; done

2. Verify success. Check that the directories have been created with below command:

ls /media

The SSH window should look similar to the picture below when finished.
