I downloaded and "burned" to a microsd the following prebuild images for the Radxa Pro:
When the computer booted up from the microsd, I used SSH and attempted to login as root using the "root" password - this did not work.
I then used SSH and logged in as rock and changed the rock password.
Next I executed "sudo su" and became root.
I changed the root password and rebooted the Radxa.
When the computer booted up, after I had previously changed the root password, I used SSH and attempted to login as root using the new password - this did not work.
I then used SSH and logged in as rock and executed "sudo su" and became root.
I checked the file /etc/ssh/sshd_config and verified that PermitRootLogin was set to yes (which it was).
Does anyone know how to configure Linaro to allow root login via SSH?
