A Few Easy Steps: Python, Build a multi-device ping tool

In this session of A Few Easy Steps, we will build a multi-device ping tool in Python.

Session Prerequisites:

  • You must have Python 2.7 installed on the host your are running this from.
  • You need at least two host to test against

Our goals for this session are:

  • Build a quick ping testing tool with Python

Lets Get Started:

Open your text editor.

Copy the following code snippet into the text editor:

# Import required libraries
import os
#
# Open Text file with host list
with open('device_file1.txt') as fname:
# Set Variable Switches to read each line int file we opened
switches = fname.read().splitlines()
# Create a for loop named switch that iterates throug the lines in switches
for switch in switches:
# Run a ping against the switch loop with 1 ping each
response = os.system("ping -c 1 " + switch)
#
#and then check the response and print is up or is down
if response == 0:
print switch, 'is up!'
else:
print switch, 'is down!'

Save the files as ping.py

Create a file called device_file1.txt

Input the hosts you want to ping as follows:

10.0.0.2
10.0.0.6
10.0.0.10
10.0.0.14
10.0.0.18
10.0.0.22
10.0.0.26
10.0.0.30
10.0.0.34
10.0.0.38

Save device_file1.txt to the same directory as ping.py

Open your terminal application

Navigate to the directory that ping.py and device_file1.txt are located

run this command

python ping.py

Your output should look something like this:
