Raspberry Pi GPIO Control Scripts

This repository contains a collection of Bash and Python scripts designed to modify the GPIO pins of a Raspberry Pi via SSH, allowing remote device control or simulation of manipulation attacks.

Project Description

The project includes:

A Bash script (ssh_preconfig.sh):

• Configures the Raspberry Pi.
• Generates SSH keys for passwordless authentication.
• Transfers the SSH keys to the Raspberry Pi.
• Installs required dependencies (WiringPi, Paramiko).
• Executes the Python script responsible for GPIO modification.

A Python script (Gpio_Mod_exit.py):

• Connects to the Raspberry Pi via SSH.
• Modifies GPIO pins based on a specified PLC input.
• Keeps the output in a high state (1) continuously.

Requirements

Hardware

• Raspberry Pi (any model with functional GPIO)
• Controlled device (e.g., LED, relay, motor, etc.)

Software and dependencies

• Raspbian OS (or any compatible Linux distribution)
• Python 3.x

Required packages

• paramiko (for SSH connection in Python)
• sshpass (for automating SSH authentication in Bash)
• WiringPi (for GPIO manipulation on Raspberry Pi)

Usage

Pre-configuration on the Raspberry Pi

Before running the scripts, make sure to:

• Enable SSH access on the Raspberry Pi.
• Create a user with SSH access permissions.
• Configure the proper GPIO access permissions.

Running the Pre-Configuration Script

To automatically set up everything, run the following command from another Linux machine:

curl -sL https://raw.githubusercontent.com/L1LBRO/Modify-GPIO-Raspberry-Pi/refs/heads/main/ssh_preconfig.sh \
| sudo bash -s <Raspberry_IP> <Passphrase> <User> <PLC_Input> <Raspberry_Password>

Where

Parameter	Description
<Raspberry_IP>	IP address of the Raspberry Pi
<Passphrase>	Security phrase for the SSH key
<User>	Raspberry Pi username
<PLC_Input>	PLC input associated with the GPIO (e.g., %IX0.4)
<Raspberry_Password>	Password of the Raspberry Pi user

PLC Input to GPIO Mapping

PLC Input	Raspberry GPIO
%IX0.0	GPIO 17
%IX0.1	GPIO 18
%IX0.2	GPIO 27
%IX0.3	GPIO 22
%IX0.4	GPIO 23
%IX0.5	GPIO 24

Notes

The script keeps the GPIO state set to 1 indefinitely, checking every 5 seconds. To stop the process, press Ctrl + C. It is recommended to test with an LED before connecting higher-power devices.
