telegram-ssh-login-notification

A simple script to check whenever a user log in or log out from your system.

Based on this script but fixed, using only PAM.

Requirements

1. A server (tested on ubuntu)
2. A telegram account
3. Create a telegram bot from the BotFather and start a chat with it.

The url of your newly created bot will look like http://t.me/your_bots_name

Copy the HTTP API: token generated by the BotFather.

4. Use @getmyid_bot bot to get your user ID. Should be in the form

Your user ID: XXXXXXXXX 
Current chat ID: XXXXXXXXX

5. Edit the script as below

What to do

1. Check your /etc/ssh/sshd_config: UsePAM yes it's mandatory.
2. git clone https://github.com/Matteounitn/telegram-ssh-login-notification.git
3. cd telegram-ssh-login-notification and here nano script.sh

HERE you HAVE TO SET:

USERID="<YOUR-ID>"
KEY="<API-KEY-OF-YOUR-BOT>" 

4. sudo nano /etc/pam.d/sshd and add the following snippet at the end of the file

session optional pam_exec.so /path/to/your/cloned/repo/telegram-ssh-login-notification/script.sh

5. sudo chmod a+x /path/to/your/cloned/repo/telegram-ssh-login-notification/script.sh
6. Not mandatory, but reccomended: sudo service ssh restart or sudo systemctl restart sshd or sudo systemctl restart ssh
