Basic Network Scanner

This script written with Python scans the local network for identifying active devices. Useful for network monitoring to check the unapproved device on your network.

Code Example:

import os

def scan_network(network):

print("Scanning network : " + network)

response = os.popen("ping -c 1 " + network).read()

if response.find('1 packets transmitted, 1 received') >= 0:

print("The network is online-" + network)

else:

print("The network is offline-" + network)

for i in range(1, 255):

scan_network("192.168.1." + str(i));

Use Case: This can be used further in the audit of networks to identify unauthorized devices that may have connected to your system.

Tip: You can modify the script to scan your entire subnet and produce an inventory of devices connected to your network.
