How to Start a Fresh Raspberry Pi without Monitor


I mean using SSH, because HDMI, mouse, keyboard, and monitor will eat up the whole space in my desk.

Prepare the Raspberry Pi OS

Firstly we need to get our microSD card with bootable Raspberry Pi OS. I recommend to use Raspberry Pi Imager to make this process easier. We just need 3 steps, download the Raspberry Pi Imager then chose our preferred OS, select the SD card, then write.

Access SSH to Raspberry Pi

By default, SSH access is not allowed. After we wrote the image of Raspbian on our SD card. Create an empty file called ssh inside the boot partition. This will enable the SSH access to your Raspberry Pi.

Raspberry Pi WIFI Auto Connect

Next, just access the Raspberry Pi using ethernet cable by using the IP address. But if we prefer to use wifi, we need to enable the auto-connect to the wifi. Still inside the boot partition, in the same folder, create a file called wpa_supplicant.conf and write down like this:

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
scan_ssid=1
ssid="your_wifi_ssid"
psk="your_wifi_password"
}

Change the paramater wifi SSID and password to match our router and save the file.

Now each time you boot up the Raspberry Pi, using your PC in the same network, you can find your Raspberry Pi already connected to the network without any user interface needed.

Finding the Raspberry Pi IP Address

There are many ways to find the Raspberry Pi IP address if we connect the Raspberry Pi via DHCP router or local network. Usually I used arp-scan for this. Install the arp-scan on your host PC:

sudo apt install arp-scan

Then scan your local network by using:

sudo arp-scan -l

ibndias@shaheen:~$ sudo arp-scan -l
 Interface: eno1, type: EN10MB, MAC: xx:xx:xx:xx:xx:xx, IPv4: 10.0.3.XXX
 Starting arp-scan 1.9.7 with 256 hosts (https://github.com/royhills/arp-scan)
 10.0.3.X    xx:xx:xx:xx:xx:xx   (Unknown)
 10.0.3.XX    xx:xx:xx:xx:xx:xx   EFM Networks
 10.0.3.XX    xx:xx:xx:xx:xx:xx   NETGEAR
 10.0.3.XXX    xx:xx:xx:xx:xx:xx   Samsung Electronics Co.,Ltd
 10.0.3.XXX    xx:xx:xx:xx:xx:xx   Apple, Inc.
 10.0.3.176    xx:xx:xx:xx:xx:xx   Raspberry Pi Trading Ltd

Here you can see that our Raspberry Pi IP is 10.0.3.176. We can start to connect via SSH by using default account.

ssh pi@10.0.3.176

And the default password is raspberry.

ibndias@shaheen:~$ ssh pi@10.0.3.176

 SSH is enabled and the default password for the 'pi' user has not been changed.
 This is a security risk - please login as the 'pi' user and type 'passwd' to set a new password.
 pi@raspberrypi:~ $

That’s it, now we can use our Raspberry Pi without cluttering our desk. 😉
