Raspberry Pi 3 Model B+ 4 USB Ports

Connecting a Raspberry Pi 3 to Wifi and add defaults

  1. Connect the Raspberry to an existing local area network by cable.
    –  I used the Ubuntu “Shared to other computers”-Network manager Setting to bridge my eth0 to my wlan0 connection providing internet access.
  2. Connect via ssh to this device
    username: pi
    password: raspberry
    – usually you don’t now the ip of the device use nmap -p 22  to search for open ssh devices
  3. Scan for local wifi networks: sudo iwlist wlan0 scan 
  4. sudo nano /etc/wpa_supplicant/wpa_supplicant.conf  and add your wifi connection data:

  5. restart the wifi and bring it to connection sudo ifdown wlan0 && sudo ifup wlan0
  6. Get the latest software status lists: sudo apt-get update
  7. Update all installed software: sudo apt-get upgrade -y
  8. Install common software to harden the system:
    sudo apt-get install x11vnc htop bmon fail2ban vnstat ufw
    x11vnc: nice tool to use VNC connections on the main x session
    htop: visualizes processes and load in color
    bmon: visualizes network traffic
    fail2ban: handles bruteforce attacks by banning Ips for a certain amount of time
    vnstat: counts network traffic over time
    ufw: makes it easier to handle ipables and configure your firewall
  9. Start the Raspberry Pi 3 Configuration Programm: raspi-config
    – expand file system to match your sd card size
    – set hostname in advanced settings
  10. enjoy your new Raspberry Pi 3 \o/
