Setup Headless RaspberryPi With SSH and WLAN

From time to time I have to setup a Raspberry Pi including ssh and wlan. But it's always super annoying to connect keyboard and screen to setup ssh and wifi. And there are other ways:

1. Use dd or etcher to flash your (raspbian) image to the Pi
2. Enable SSH
   • Mount sd card on your Computer (not on your raspberry pi)
   • Create an empty file named ssh and store it on the sd card on /boot

3. Enable Wifi

   • create /boot/wpa_supplicant.conf

   ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
   network={
       ssid="YOUR_SSID"
       psk="YOUR_WIFI_PASSWORD"
       key_mgmt=WPA-PSK
   }
   

   • Pi will get an IP adress from your DHCP-Server
   • unmount
4. Start Rarspberry Pi
   • put in sd card
   • power on

5. Get IP Adress

   On your computer:

   nmap -sP 192.168.XXX.1/24  # replace XXX
   

   • most likely the hostname you are locking for is rasberrypi ;)

6. Connect to Raspberry Pi:

   ssh pi@IpFromPrevCommand
   # pw: raspberry
   

7. Configure system

   sudo raspi-config
   # Change default password!
   # Update System
   # Change settings
