IP(v4) notifier

This shell script just notifies you on telegram if the IP of the host machine has changed:

Dependencies

• curl
• Telegram bot: How do I create a bot?

Set up guide

Clone the repo and change directory to the downloaded folder:

git clone https://github.com/marcFernandez/ip-notifier.git && cd ip-notifier

Give the script execution permissions:

chmod +x check_ip.sh

In order for it to work, you just need to replace the variables noted with <YOUR_whatever> in the script. First, obtain your bot token using @BotFather on Telegram (guide) and replace it in the following line:

# line 8
BOT_TOKEN="<YOUR_BOT_TOKEN>"

Then, retrieve your chat id by sending a message to your bot and quickly checking the url https://api.telegram.org/bot<YOUR_BOT_TOKEN>/getUpdates, replacing <YOUR_BOT_TOKEN> by your actual token. You should see a JSON in the browser:

Replace it in the following line:

# line 17
CHAT_ID="<YOUR_CHAT_ID>"

You can test it by just executing the script:

./check_ip

Execution

I personally run it using a cron in my Raspberry Pi every 20min, but you can execute it using any other method.
