Setting Up a Raspberry Pi for Remote Access Without a Monitor or Keyboard

Install the following software for this tutorial

• Raspberry Pi Imager
• RealVNC

First, start the raspberrypi Imager

When opened, the following configuration screen will be launched.

This time, I'll install Raspberry Pi OS (64-bit) Desktop on a 32GB microSD card, using the Desktop version for graphical display via VNC.

Write with the following settings

Press 「Next」

When asked 「Would you like to apply OS customisation settings?」, press 「EDIT SETTINGS」.

Under the 「GENERAL」 category, set up Wi-Fi and password in the 「OS Customization」 screen.

Select 「SERVICE」 and enter your Wi-Fi and password. If you wish to configure using a public key, select 「SERVICE」 next to 「GENERAL」 and choose 「Allow public-key authentication only. Set authorized_keys for 'pi':'」

And click「SAVE」

When asked 「Would you like to apply OS customisation settings?」, press「YES」.

Please wait a moment while the Raspberry Pi OS is being written to the microSD card.

The display will show 「verifying...」 and after a short while, the process will be completed.

Click 「CONTINUE」 and then follow the on-screen instructions to remove the microSD card.

Next, insert the microSD card into the Raspberry Pi and power it on.

Enter the following command in the terminal to connect to the Raspberry Pi via SSH. If a password has been set, enter the password to log in.

ssh [e-mail]

or

ping [e-mail]

Check IPAdress

ssh [e-mail]（IP Address）

If configured as follows, the 'hostname,' 'Username,' and 'Password' will be as follows.

「hostname」: 「raspberrypi」
「Username」：「pi」
「Password」：「raspberry」

During the first login, you will be asked a question like the following, to which you should respond with 'yes'.

ssh pi@(IPAdress)
The authenticity of host '10.207.171.xxx (10.207.171.xxx)' can't be established.
ED25519 key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxx.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])?

Yes

Once logged in, you will see a prompt like 「pi@raspberrypi:~ $」, indicating that you have successfully SSH connected to the Raspberry Pi.

Linux raspberrypi 6.1.0-rpi7-rpi-v8 #1 SMP PREEMPT Debian 1:6.1.63-1+rpt1 (2023-11-24) aarch64

pi@raspberrypi:~ $

Having established a connection via SSH in the CLI, I would now like to connect graphically using VNC. To do this, it's necessary to enable VNC connections by running 「sudo raspi-config」.

sudo raspi-config

The screen will change to a blue background, switching to the interface for configuring Raspberry Pi settings.

Select 「3 Interface Options」, Click「Enter」

Select「I2 VNC」

「When asked 'Would you like the VNC server to be enabled?」 select 「Yes」.

This will momentarily switch back to the original black screen. Afterwards, 「The VNC Server is enabled」 will be displayed, so select 「OK」.

Now that VNC is enabled, next launch Real VNC.

Enter the IP address in the input field at the top

Finally, enter the Username and Password you set earlier

If the IP address is entered correctly, the following screen will be displayed for the first time, so click 「Continue」.

Finally, enter the Username and Password you set earlier.

Doing so will display the Raspberry Pi's home screen.
