Initially designed to run on a Raspberry PI, probably it can run on many other Linux distributions.

Estimated time: 20'

• Unistall process

1.1 - Install 'Raspberry Pi OS'

• Instructions https://www.raspberrypi.org/documentation/installation/installing-images/
• Lite version (without Desktop) is enough for Pi.Alert

1.2 - Activate ssh

• Create a empty file with name 'ssh' in the boot partition of the SD

1.3 - Start the raspberry

1.4 - Login to the system with pi user

user: pi
password: raspberry

1.5 - Change the default password of pi user

passwd

1.6 - Setup the basic configuration

sudo raspi-config

1.7 - Optionally, configure a static IP in raspi-config

1.8 - Update the OS

sudo apt-get update
sudo apt-get upgrade
sudo shutdown -r now

2.1 - Links & Doc

• https://pi-hole.net/
• https://github.com/pi-hole/pi-hole
• https://github.com/pi-hole/pi-hole/#one-step-automated-install

2.2 - Login to the system with pi user

2.3 - Install Pi-hole

curl -sSL https://install.pi-hole.net | bash

• Select "Install web admin interface"
• Select "Install web server lighttpd"

2.4 - Configure Pi-hole admin password

pihole -a -p PASSWORD

2.5 - Connect to web admin panel

hostname -I

or this one if have severals interfaces

ip -o route get 1 | sed 's/^.*src \([^ ]*\).*$/\1/;q'

• http://192.168.1.x/admin/
• (replace 192.168.1.x with your Raspberry IP)

2.6 - Activate DHCP server

• Pi-hole admin portal -> Settings -> DHCP -> Mark "DHCP server enabled"

2.7 - Add pi.alert DNS Record

hostname -I

or this one if have severals interfaces

ip -o route get 1 | sed 's/^.*src \([^ ]*\).*$/\1/;q'

• Pi-hole admin portal -> Local DNS -> DNS Records -> Add new domain /IP
  • pi.alert 192.168.1.x
  • (replace 192.168.1.x with your Raspberry IP)

2.8 - Deactivate your current DHCP Server (usually at your router or AP)

2.9 - Renew your computer IP to unsure you are using the new DHCP and DNS server

• Windows: cmd -> ipconfig /renew
• Linux: shell -> sudo dhclient -r; sudo dhclient
• Mac: Apple menu -> System Preferences -> Network -> Select the network -> Advanced -> TCP/IP -> Renew DHCP Lease

If you have installed Pi.hole, lighttpd and PHP are already installed and this block is not necessary

3.1 - Install apt-utils

sudo apt-get install apt-utils -y

3.2 - Install lighttpd

sudo apt-get install lighttpd -y

3.3 - If Pi.Alert will be the only site available in this webserver, you can redirect the default server page to pialert subfolder

sudo mv /var/www/html/index.lighttpd.html /var/www/html/index.lighttpd.html.old
sudo ln -s ~/pialert/install/index.html /var/www/html/index.html

3.4 - Install PHP

sudo apt-get install php php-cgi php-fpm php-sqlite3 -y     

3.5 - Activate PHP

sudo lighttpd-enable-mod fastcgi-php
sudo service lighttpd restart

3.6 - Install sqlite3

sudo apt-get install sqlite3 -y

4.1 - Install arp-scan utility and test

sudo apt-get install arp-scan -y
sudo arp-scan -l

4.2 - Install dnsutils & net-tools utilities

sudo apt-get install dnsutils net-tools -y

4.3 - Test Python

New versions of 'Raspberry Pi OS' includes Python. You can check that Python is installed with the command:

python -V

New versions of Ubuntu includes Python 3. You can choose between use python3 command or to install Python 2 (that includes python command).

If you prefer to use Python 3, in the next installation block, you must update pialert.cron file with the correct command: python3 instead of python.

python3 -V

4.4 - If Python is not installed in your system, you can install it with this command:

sudo apt-get install python

Or this one if you prefer Python 3:

sudo apt-get install python3

5.1 - Download Pi.Alert and uncompress

cd
curl -LO https://github.com/pucherot/Pi.Alert/raw/main/tar/pialert_latest.tar
tar xvf pialert_latest.tar
rm pialert_latest.tar

5.2 - Public the front portal

sudo ln -s ~/pialert/front /var/www/html/pialert

5.3 - Configure web server redirection

If you have configured your DNS server (Pi.hole or other) to resolve pi.alert with the IP of your raspberry, youy must configure lighttpd to redirect these requests to the correct pialert web folder

sudo cp ~/pialert/install/pialert_front.conf /etc/lighttpd/conf-available
sudo ln -s ../conf-available/pialert_front.conf /etc/lighttpd/conf-enabled/pialert_front.conf
sudo /etc/init.d/lighttpd restart

5.4 - If you want to use email reporting with gmail

• Go to your Google Account https://myaccount.google.com/
• On the left navigation panel, click Security
• On the bottom of the page, in the Less secure app access panel, click Turn on access
• Click Save button

5.5 - Config Pialert parameters

sed -i "s,'/home/pi/pialert','$HOME/pialert'," ~/pialert/config/pialert.conf          
nano  ~/pialert/config/pialert.conf

• If you want to use email reporting, configure this parameters

  REPORT_MAIL     = True
  REPORT_TO       = 'user@gmail.com'
  SMTP_SERVER     = 'smtp.gmail.com'
  SMTP_PORT       = 587
  SMTP_USER       = 'user@gmail.com'
  SMTP_PASS       = 'password'

• If you want to update your Dynamic DNS, configure this parameters

  DDNS_ACTIVE     = True
  DDNS_DOMAIN     = 'your_domain.freeddns.org'
  DDNS_USER       = 'dynu_user'
  DDNS_PASSWORD   = 'A0000000B0000000C0000000D0000000'
  DDNS_UPDATE_URL = 'https://api.dynu.com/nic/update?'

• If you have installed Pi.hole and DHCP, activate this parameters

  PIHOLE_ACTIVE   = True
  DHCP_ACTIVE     = True

5.6 - Update vendors DB

python ~/pialert/back/pialert.py update_vendors

or

python3 ~/pialert/back/pialert.py update_vendors

5.7 - Test Pi.Alert Scan

python ~/pialert/back/pialert.py internet_IP
python ~/pialert/back/pialert.py 1

or

python3 ~/pialert/back/pialert.py internet_IP
python3 ~/pialert/back/pialert.py 1

5.8 - Update crontab template with python3

If you prefer to use Python 3 (installed in the previous block), you must update pialert.cron file with the correct command: python3 instead of python

sed -i 's/python/python3/g' ~/pialert/install/pialert.cron

5.9 - Add crontab jobs

(crontab -l 2>/dev/null; cat ~/pialert/install/pialert.cron) | crontab -

5.10 - Add permissions to the web-server user

sudo chgrp -R www-data ~/pialert/db
chmod -R 770 ~/pialert/db

5.11 - Check DNS record for pi.alert (explained in point 2.7 of Pi.hole installation)

• Add pi.alert DNS Record

  hostname -I
  

  or this one if have severals interfaces

  ip -o route get 1 | sed 's/^.*src \([^ ]*\).*$/\1/;q'
  

  • Pi-hole admin portal -> Local DNS -> DNS Records -> Add new domain /IP
    • pi.alert 192.168.1.x
    • (replace 192.168.1.x with your Raspberry IP)
