I am using two Raspberry Pis : one gets triggered from the particle cloud, connects to the second over ssh and executes a bash script on it. I got it running using the following code: First Pi, firmware: #include <fcntl.h> #include <unistd.h> #include <stdio.h> #include "Particle.h" void doCall(…

I think when the Pi calls the script through the firmware it does it as root. You should check if the ssh fingerprint works with root/sudo.

can a maintainer please try to reproduce? I see no reason why a normal ssh fingerprint should not work. If what @nrobinson2000 says is true, and the firmware runs a Process::run as root, it should at least have an overload specifying the user one would like to run as.

Ashamed I didn’t think about it earlier. Thank you loads, @nrobinson2000 ! It works now.
