This is part #3 of my adventures in Building the Internet of Things with the Raspberry Pi. You can read about Getting started with Raspberry Pi 3 and my first Hello Blinky 1.0 with the Raspberry Pi 3.
In this post I want to install Raspbian via NOOBS, configure the security-critical settings and install the necessary packages to access the Raspberry Pi GUI from a computer with a Remote Desktop Connection.
Install Rasbian via NOOBS
This step is pretty straightforward: you will need a monitor, keyboard and mouse. If you have a pre-installed SD card with NOOBS, select to install Raspbian. Otherwise you can prepare an SD card with NOOBS. See here.
Connect the RPi to the internet via Wifi.
sudo apt-get install xrdp (Remote Desktop)
sudo apt-get install geany (Notepad++ for Linux)
- the console remembers commands after reboot.
- sudo – super user do
- apt – package manager
Menu => Preferences => Add/Remove software
Do every few weeks:
sudo apt-get update
sudo apt-get update
Hint: gets the new list of packages.
sudo apt-get upgrade
Hint: downloads and installs the updates.
Check ip address:
Hint: Similar to ipconfig and displays following configuration: eth0 – cable, lo – localhost, wlan0.
Set static ip address
Hint: run Geany with admin rights to change configuration files, otherwise it’s write-protected. Important: it’s another session!
/etc – contains config files
/etc/network/interfaces – network configuration
Add following configuration:
iface eth0 inet static
iface eth0 inet manual
sudo etc/init.d/networking restart
Control panel => Network and Internet => Connections => Local network => Properties => IPv4 => Set IP address and Mask
ping RPi IP
Remote desktop to RPi IP
Hint: we can have multiple sessions with same user directly on the RPi and with remote desktop at the same time.
Changing the login information is critical, default login is the same for all RPi.
Menu => Raspberry Pi Configuration
– change password,
– change hostname,
– boot to desktop/CLI (command line shell, can start GUI anytime from CLS)
– autologin is ok
– SSH server; DON’T run on port 22
– Don’t connect RPi direct in internet, use router, vpn
– Rename default username Pi: create temporary user without home, make user admin, rename pi and move home
Menu => Interfaces
- Enable SSH (Putty)
24/7 continuous operation
- Watchdog – auto-restart when problems occur => activate, configure and install Watchdog
- fail2ban – for connection via SSH, 5 tries to login and lock out for 10 minutes, against brute force attacks
sudo apt-get install fail2ban
sudo nano filename (GNU Nano text editor)
