Discovered the issue, because my Zimaboard cannot connect to a 2TB drive on my Nvidia Shield. It is ethernet connected to my home network. The INTERNAL IP works to connect to the Zimaboard from my iMac (also ethernet connected to same network).
I attempted to ping the drive from my iMac (successfully), but a ping command from the Zimaboard fails. Likewise, when I attempted to ping an external site from the Zimaboard (ping google.com), I got no results. When I open a terminal window on my iMac, I can ping.
I have attempted several things. For example:
Evidently, there is no firewall. When I type the command in Zima OS terminal:
sudo ufw disable
I get the message: “sudo: ufw: command not found”
If I give the command:
sudo apt update
I get the message: “sudo: apt: command not found”
As a NOOB, I WANT to learn, but I am in “over my head.”
Who can help me?
