PythonPing to determine if Router is Up

We can use ping to determine whether a host is up or down, in my case I use it to determine whether a power failure has occurred. I needed a script to automatically ping my router and if it does not respond, it will trigger something like an automated emergency shutdown of my server. To do this using python, I researched on a package from the net.

PythonPing – A simple way to ping in Python

I found this PythonPing, it is a simple python package that allows you to ping using python (hence the name), but your script must run with root privileges.

Install pythonping package as root

$ sudo python3 -m pip install  pythonping

Script to check if router is pingable, return true if yes.

from pythonping import ping
import time

routerA = ping('172.16.1.1')
isAliveA = str(routerA._responses[0].success)

print(str(time.ctime(time.time())))
if (isAliveA == "False"):
    print("ROUTER A FAIL")
else:
    print("ROUTER A OK")

Sample output:

$ sudo python3 ./ping.py
Sun Mar  1 20:15:58 2020
ROUTER A OK
