pingcheck is a bash script tool to monitor a network ip and alert when host is unreachable.
My routers in my local area network need rebooted every so often. This tool lets me know what router or device needs rebooted. It can also be used for general network/host connectivity monitoring.
Usage: ./pingcheck [network ip address] [network nickname]
Example: ./pingcheck 192.168.1.1 Home
You need to run the following commands to enable cron to launch a gui tool (notify-send). These will add localhost to the access control list, then enable the access control we created
$ xhost +local:
$ xhost
The we need to update cron for the user this will run under
$cron -e -u username
Add this to your cron file
* * * * * env DISPLAY=:0.0 /home/username/bin/pingcheck 192.168.1.1 HomeRouter 2>&1
This bash script depends on notify-send command in the notify-osd package.
sudo apt-get install notify-osd
Here is an example screenshot of what the notifcation looks like
