Headless First-Time Boot of RPi

This post describes how to connect the raspberry pi (with a interface by Raspberry Pi foundations) to the internet and enable the ssh, all on the first boot. This post is meant mainly for my reference, while also giving the actual reference.

Connecting to WiFi on first boot

Download the raspbian image and write the image to the SD card.
Navigate to the boot directory of the image.
Create a new file there with the name wpa_supplicant.conf.

In the above created file, add the following into it:

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
      ssid="SYSLink123"
      psk="hellowifi"
      key_mgmt=WPA-PSK
}

In the same navigated directory, create a file without any extension and name it as ssh.

Checking the connection

To find if process was successful, run the following command: $ sudo nmap -sn 192.168.0.0/24
