3. Boot the Raspberry Pi: Insert the SD card into the Raspberry Pi, connect it to a monitor, keyboard, and power supply, and then turn it on. The Raspberry Pi will boot up with SSH enabled.
4. Connect to Wi-Fi (optional): If you plan to use Wi-Fi instead of Ethernet to connect your Raspberry Pi to the network, you can create a file named “wpa_supplicant.conf” in the root directory of the SD card. Edit the file to include your Wi-Fi network details, such as SSID and password, following this format:
“`
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=
network={
ssid=””
psk=””
key_mgmt=WPA-PSK
}
“`
5. Find the IP address: To establish an SSH connection to your Raspberry Pi, you need to know its IP address. You can find this by logging in to your router’s administration panel or using a network scanner tool like ‘nmap’ or ‘Angry IP Scanner’.
