Option 2: Use the raspi-config command.
In the terminal, enter sudo raspi-config.
Select Interfacing Options.
Enabling SSH requires you to reboot your Raspberry Pi. Go ahead and do that now if you haven't already.
For more information on SSH, review the official Raspberry Pi Secure Shell access tutorial.
Once SSH is configured, you just need to send a few commands for the connection to go through and you'll be able to control your Raspberry Pi-controlled-RVR+ or RVR from your laptop, desktop, or other device!
Getting your Raspberry Pi IP Address
You'll need the IP address of the Raspberry Pi to SSH into it, so the next thing we'll need to do is gather that information. Get the IP address of the Pi by jumping into its terminal and entering:
Your IP address is often the same, especially as long as you stay on the same wifi network, but it can change, so, if you are having issues connecting, you can run the above command again (from the Raspberry Pi, with a monitor/mouse/keyboard plugged in) to check if there have been any changes.
Try out an SSH connection
It's a good idea to test the SSH connection (in the terminal on your desktop/laptop) and make sure that it works before completely abandoning your Raspberry Pi's monitor/mouse/keyboard setup.
On Remote Computer
The device you want to use to control the RVR+/RVR must be on the same wifi network as your Raspberry Pi. On your laptop/desktop/etc., open the the terminal and use this command to access your Raspberry Pi. Make sure to replace "ipaddress" with the IP Address of your Pi.
Once you run this command, you'll be prompted for the password to your Raspberry Pi. For security, you'll get no indication that your password is being typed as you type it.
If you have installed a new Raspberry Pi OS and have previously used SSH you may encounter an error at this step. Try regenerating your SSH keys with this command.
ssh-keygen -R ipAddressOfYourPiHere
You should now get a success message and be able to work in the terminal to control your Raspberry Pi the same way you could when you had a monitor plugged into it.
Type the following command to shutdown your Raspberry Pi and get ready to connect it to RVR+/RVR in the next step.
sudo shutdown now
You should try to always shut down your Raspberry Pi properly before removing power (unplugging it or turning off a RVR+/RVR that is powering it). SD card corruption may occur if your Pi is not shut down properly.
