x. Download and install the Raspbian image, follow the install instructions:

https://www.raspberrypi.org/

x. install the micro SD card, connect keyboard, mouse, screen and finally power

Boot and wait for the GUI to load.

x. menu -> Preferences -> Raspberry pi configuration

change hostname

change default pi password

change timezone

when done navigate to finish

(optionally) you can change the boot behaviour to boot to CLI not GUI (saves CPU cycles and power if you’re using the unit “headless”).

reboot

x. sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=GB


network={

	ssid=“yourSSID”	
	psk=“password”
	key_mgmt=WPA-PSK

}

network={
  ssid=“WPA_EnterpirseSSID”
  scan_ssid=1
  key_mgmt=WPA-EAP
  pairwise=CCMP TKIP
  group=CCMP TKIP
  eap=PEAP
  identity=“domain_username@doman.com"
  password=“domain_password”
  phase1="peapver=0"
  phase2="MSCHAPV2"
}


x. disable wireless power management (some wifi dongles go to power save and cause issues)
sudo nano /etc/network/interfaces

add
iface wlan 0 inet manual 
	wireless-power off

iface wlan 1 inet manual
 	wireless-power off


x. now that you’re online update the software on your pi

sudo apt-get update
sudo apt-get upgrade
sudo rpi-update
reboot

x. install the display library

sudo curl -sS get.pimoroni.com/unicornhat | bash

x. install some useful packages like vim and mail utilities.

sudo apt-get install -y vim 
sudo apt-get install -y ssmtp 
sudo apt-get install -y mailutils

this one fixes the random number generator:
sudo apt-get install rng-tools

optional if you're using 'lite' version of rasbian:
sudo apt-get install python-requests

x. 

sudo git clone https://github.com/Kris-Sekula/ACI-Health
cd ACI-Health

sudo mv monitor.py /boot/
sudo mv mailmyip.sh /boot/
sudo mv vim-rc .vimdc
sudo mv ssmtp.conf /etc/ssmtp/ssmtp.conf


x. edit email settings, change hostname and outgoing smtp server
sudo vi /etc/ssmtp/ssmtp.conf

x. test email
echo "Hello world email body" | mail -s "Test Subject" me@domain.com

x. Install cron job to start the monitor function and send email 

sudo crontab -e

@reboot sleep 120 && bash /boot/mailmyip.sh
@reboot sudo /usr/bin/python /boot/monitor.py

x. disable ipv6 if you don’t need it
sudo vi /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 1
