Shutting Down Multiple Raspberry Pi Linux Systems: Network SSH Access Control

Shutting Down Multiple Raspberry Pi Linux Systems: Network SSH Access Control

In this article, we will discuss how to control SSH access to multiple Raspberry Pi Linux systems within a local network (50.100.x.x with IP addresses ranging from 50.100 to 50.106). The goal is to shut down the Raspberry Pi systems remotely via SSH without having to physically access each device.

Prerequisites

• Multiple Raspberry Pi systems with Raspbian OS installed
• SSH enabled on all Raspberry Pi systems
• Local network with IP addresses ranging from 50.100 to 50.106

Setting Up SSH Access Control

To control SSH access to multiple Raspberry Pi systems, we need to set up a centralized management system. One way to achieve this is by using a configuration management tool such as Ansible. In this example, we will demonstrate how to use Ansible to manage multiple Raspberry Pi systems and control SSH access.

Step 1: Installing Ansible

To install Ansible, run the following command on your local system:

sudo apt-get install ansible

Step 2: Configuring Ansible Inventory

Create a new inventory file called rpi in the /etc/ansible/hosts directory:

sudo nano /etc/ansible/hosts

Add the following lines to the inventory file:

[rpi]
50.100.x.x
50.101.x.x
50.102.x.x
50.103.x.x
50.104.x.x
50.105.x.x
50.106.x.x

Step 3: Creating Ansible Playbook

Create a new playbook file called shutdown.yml in a new directory called ansible:

mkdir ansible
nano ansible/shutdown.yml

Add the following lines to the playbook file:

---
- hosts: rpi
  become: yes
  tasks:
    - name: Shutdown Raspberry Pi system
      command: shutdown -h now
      async: 0
      poll: 0
      ignore_errors: yes

Step 4: Running Ansible Playbook

Run the following command to execute the playbook:

ansible-playbook -i rpi shutdown.yml

In this article, we have discussed how to control SSH access to multiple Raspberry Pi Linux systems within a local network. We have demonstrated how to use Ansible to manage multiple Raspberry Pi systems and control SSH access. By following the steps outlined in this article, you can shut down multiple Raspberry Pi systems remotely via SSH without having to physically access each device.
