How to connect your Raspeberry PI at the first time boot after flash the image
井民全, Jing, mqjing@gmail.com
This document show you how to wirelessly ssh connect to your Raspberry PI that without the monotor and keyboard for the first time boot after downloaded the image. Briefly, In order to configure the WI-FI WPA, you should mount the SD card to your host, create the wpa_supplicant.conf on the boot partition, enable the ssh function and put it back to the Raspberry Pi for boot system. Wait a seconds, try to use arp-scan to scan the subnet to find out the raspberry PI IP. Now, you can get access to the Pi. Here is the quick guide.

2.2. Detal Procedure
Step 1: Enable ssh
|
cd to the boot device touch ssh |
Step 2: Setup Wirlesss WPA
vi wpa_supplicant.conf
File: wpa_upplicant.conf
|
country=us update_config=1 ctrl_interface=/var/run/wpa_supplicant network={ scan_ssid=1 ssid="MyNetworkSSID" psk="Pa55w0rd1234" } |
If you are in Windows, plase notice the EOL conversion.
Step 3: Boot the system
2.3. Scan the Raspberry PI IP
2.3.1. Linux
Command
sudo arp-scan - I ens33 --localnet
Where the ens33 is my nic name, you can find yours by using ip a command. See the detail info.
E.g.
Or you can use following instructions to find the PI's IP.
sudo arp-scan - I ens33 --localnet | grep pi
2.3.2. Windows
Command
arp -d :: Delete ARP entry at first
arp -a :: List ARP entry
E.g.
Power on the Raspeberry PI
Run the command:
arp -a
Look-up the Mac-add
Or
arp -a | find "b8-27-eb"
