With the following script we monitor the SSH login on a server and send a notification via Telegram API.

This way you will get a notification in real time when someone logs in to your server via SSH. For me this is a valuable security feature.

Telegram Notification on successful SSH Login

telegram-send Python Script

First, we create the following Python script, which is used to send messages to Telegram’s API.

You can use this script for the SSH-watcher, but also for cronjobs or other commands that send output to the CLI.

vim telegram-send.py

import sys
import requests

TELEGRAM_API_KEY = "<your_api_key>"
TELEGRAM_CHAT_ID = "<your_chat_id>"

message = " ".join(sys.argv[1:])

if not message:
    print("Please provide a message to send.")

# Use the Telegram API to send the message with markdown formatting
response = requests.get(

if response.status_code == 200:
    print("Message sent successfully.")
    print("Failed to send message. Please check your API key and chat ID.")

To use this script, you will need to replace <your_api_key> and <your_chat_id> with your own API key and chat ID. You can get your API key by creating a new bot with the BotFather and chat ID by starting a conversation with your bot and sending a message to it.

You can then run the script like this: python telegram-send.py Message

Now move the script to a persistent location, such as: mv telegram-send.py /usr/bin/telegram-send.py

/etc/login.d/ Script

Now it is about creating a script which will be executed on every SSH login.

For this it is enough to put a bash script in the /etc/login.d/ directory. Once a user successfully logs in, the script is called and we are notified of a login via Telegram.

vim /etc/profile.d/login-notify.sh


login_ip="$(echo $SSH_CONNECTION | cut -d " " -f 1)"
login_date="$(date +"%a %e %b %Y, %R")"

message="*Host:* $HOSTNAME"$'\n'"*User:* $login_name"$'\n'"*IP:* $login_ip"$'\n'"$login_date"

python3 /usr/bin/telegram-send.py "$message"

Exclude yourself from the notification

If you want to exclude your own IP address from the warning, you can use this example. This will not trigger a notification if the SSH login is coming from your own IP address.


login_ip="$(echo $SSH_CONNECTION | cut -d " " -f 1)"
login_date="$(date +"%a %e %b %Y, %R")"

message="*Host:* $HOSTNAME"$'\n'"*User:* $login_name"$'\n'"*IP:* $login_ip"$'\n'"$login_date"

if [[ $login_ip != "<your-ip-address>" ]]
    python3 /usr/bin/telegram-send.py "$message"

Replace <your-ip-address> with your own static IP-address.


Open a new Terminal and try to connect with ssh [email protected].


You should receive an instant notification from your Telegram Bot.
