Overview

Python program that log public IP address in SQLite database.
Only new/change IP is added to DB, if IP is same as last time program was run, then only last_time_seen is updated.
Made for Raspberry Pi Zero 2 W.
Raspberry Pi Zero 2 W, at least in my experience get stuck ever few days, so there is gap table to track when it got stuck.

Usage

git clone https://github.com/sasa-buklijas/ip_logger
cd ip_logger

python -m venv venv-3_11_2
. ./venv-3_11_2/bin/activate

python -m pip install -r requirements.txt

python ip_to_sqlite.py
# this will make 2x files
# public_ip.db -> what is SQLite DB
# index.html   -> HTML report with IP addresses, first seen, last, duration, etc

Idea is to run python ip_to_sqlite.py in crontab

@reboot
* * * * * cd /home/pi/ip_logger && ./venv-3_11_2/bin/python ip_to_sqlite.py

# look at index.html via web browser
# you can also server index.html as static webpage with web server (eg. apache, nginx, etc)

Supported Python Version

Supported Python version is .python-version
Others are probably also working, this one is used/tested by myself.

SQLite database structure

2x tables:

$ sqlite3 public_ip.db ".schema"

CREATE TABLE public_ip (
	id INTEGER NOT NULL,
	ip TEXT,
	first_time_seen FLOAT,
	last_time_seen FLOAT,
	PRIMARY KEY (id)
);

CREATE TABLE gap (
	id INTEGER NOT NULL,
	start FLOAT,
	"end" FLOAT,
	PRIMARY KEY (id)
);
