Router ping and notification in private messages via telegram bot

Installation

1. Download the necessary files or clone this project anywhere.

git clone https://github.com/dog1912/ping-and-notifications-to-telegram.git

2. Add your domain name or ip address for the router to the ping.sh script files. For convenience, you can add an entry in the hosts:

8.8.8.8 host1
1.1.1.1 host2

3. Edit the value of TOKEN and "chat id channel" to send a notification to telegram

TOKEN="Token bot from telegram"
TARGETS=([host1]="chat id channel" [host2]="chat id channel")

4. Add the task to the crontab with flock to prevent re-runs. Instead of /scripts/ you need to specify your path

*/1 * * * * flock -n /var/tmp/host1.lock -c "/scripts/ping.sh host1"  >/dev/null 2>&1
*/1 * * * * flock -n /var/tmp/host2.lock -c "/scripts/ping.sh host2"  >/dev/null 2>&1
