Network Hound

This is a network packet sniffer that captures and analyzes network packets on a given interface. The tool is implemented using Scapy and Pandas. The packets can be saved to a csv file for later analysis. The tool can filter the packets based on TCP and/or UDP protocols and source and destination IP adresses.

Features

• Sniff packets on a given interface
• Filter packets based on TCP and/or UDP protocols and source and destination IP addresses
• Display captured packets on the console (in a readable table format)
• Save captured packets to a csv file for later analysis

Usage

python network_hound.py [-h] [-i INTERFACE] [-t] [-u] [-s SOURCE] [-d DESTINATION] [-o OUTPUT]

optional arguments:
-h, --help show this help message and exit
-i INTERFACE, --interface INTERFACE
The interface name (default: wlo1)
-t, --tcp Sniff TCP packets
-u, --udp Sniff UDP packets
-s SOURCE, --source SOURCE
Source IP address to filter by
-d DESTINATION, --destination DESTINATION
Destination IP address to filter by
-o OUTPUT, --output OUTPUT
Save packets to a file

Requirements

• Scapy
• PrettyTable
• Pandas
• argparse
• socket
• time

Installation

Recommended Way of using pip

python -m pip install scapy pandas argparse socket time prettytable

OR

python -m pip install -r requirements.txt

Examples

To sniff TCP packets on the default interface(wlo1):

python network_hound.py

To sniff both TCP and UDP packets on the default interface:

python network_hound.py -t -u

To filter packets based on source and destination IP addresses:

python network_hound.py -t -u -s <source_ip> -d <destination_ip>

To save captured packets to a file:

python network_hound.py -t -o <file_name>

Warning!

CSV files will be write-protected, don't try to rewrite them again.
