I have some raspberrys that run some softwares, I want to be able to connect and configure then, update the software or extract some paramters. What are the Standards for D2D via SSH communication?

My goals:

• A program that can connect with a Raspberry via SSH and run commands.

• The raspberrys already exists and are already configurated

• I have the IP, Password and User for each of then

• Fully automated
