Setting up your Raspberry Pi to receive commands by email
Before we get started, you will need to set up your Raspberry Pi to receive and execute commands by email. Follow these steps:
Step 1: Install and configure Postfix on your Raspberry Pi
Postfix is a mail transfer agent that will allow your Raspberry Pi to receive emails. Here is how you can install and configure Postfix:
– Open the terminal on your Raspberry Pi and enter the following command:
“`
sudo apt-get install postfix
“`
– During the installation, you will be prompted to select the “Internet Site” configuration. Follow the prompts and enter the required information.
– Once the installation is complete, edit the Postfix configuration file by entering the following command:
“`
sudo nano /etc/postfix/main.cf
“`
– Add the following lines to the end of the configuration file:
“`
virtual_alias_maps = hash:/etc/postfix/virtual
“`
– Save and exit the configuration file by pressing `Ctrl+X`, then `Y`, and finally `Enter`.
Step 2: Set up a virtual alias
In this step, you will set up a virtual alias that will allow your Raspberry Pi to execute commands sent by email.
– Enter the following command to edit the virtual alias file:
“`
sudo nano /etc/postfix/virtual
“`
– Add the following line to the end of the file:
“`
command@yourdomain.com pi
“`
– Save and exit the file by pressing `Ctrl+X`, then `Y`, and finally `Enter`.
– Run the following command to apply the changes you have made:
“`
sudo postmap /etc/postfix/virtual
“`
– Finally, restart Postfix to ensure that it is using your new configuration:
“`
sudo service postfix restart
“`
Sending commands to your Raspberry Pi by email
Now that your Raspberry Pi is set up to receive commands by email, you can send commands to it from any email address. Here’s how:
– Open your email client and create a new email.
– In the “To” field, enter `command@yourdomain.com` (replace `yourdomain.com` with your actual domain name).
– In the email body, enter the command you want to run on your Raspberry Pi. For example, to update your Raspberry Pi, you can enter the following command:
“`
sudo apt-get update && sudo apt-get upgrade -y
“`
– Send the email.
– Your Raspberry Pi will receive the email and execute the command.
