Network Port Traffic Monitoring System

Introduction

This system is a network port traffic monitoring tool based on Python and PyQt5. It can capture and analyze network packets in real-time, providing detailed traffic statistics and visual reports.

Features

1. Real-time Capture: Capable of capturing network packets in real-time and performing real-time analysis.
2. Traffic Statistics: Provides detailed traffic statistics, including packet count, traffic size, etc.
3. Visual Reports: Generates detailed traffic statistics reports and provides visual charts for display.
4. User-friendly Interface: Developed using PyQt5, the interface is simple, intuitive, and easy to operate.

Installation and Usage

1. Install Dependencies: Using pip:

   pip install -r requirements.txt

   Or using conda:

   conda install --file requirements.txt

2. Run the Program: On macOS, you need to run the program with sudo privileges:

   sudo python main.py

   On Windows, run the program directly:

   python main.py

Database Configuration

In order to use the database, you need to configure the database first.

Database Setup

1. The system uses MySQL for data persistence and historical analysis
2. Create a new MySQL database and execute the following SQL:

CREATE TABLE capture_sessions (
  id INT AUTO_INCREMENT PRIMARY KEY,
  start_time DATETIME,
  end_time DATETIME
);

CREATE TABLE packets (
  id INT AUTO_INCREMENT PRIMARY KEY,
  session_id INT,
  packet_data JSON,
  capture_time DATETIME,
  FOREIGN KEY (session_id) REFERENCES capture_sessions(id)
);

Database Settings

1. Access database settings through the toolbar settings icon
2. Configure the following parameters:
   • Host: MySQL server address
   • Port: MySQL server port (default 3306)
   • Database: Database name
   • Username: MySQL username
   • Password: MySQL password

Database Features

1. Data Persistence

   • Automatically saves captured packet information
   • Stores detailed packet metadata in JSON format
   • Maintains capture session history

2. Historical Analysis

   • View historical traffic patterns
   • Generate traffic statistics by time period
   • Compare traffic across different capture sessions

3. Data Security

   • Encrypted database credentials storage
   • Secure connection handling
   • Password protection for sensitive data

Usage Examples

1. View Historical Data

   • Click the "Historical Chart" button in the toolbar
   • Select date range for analysis
   • Choose specific processes or view all traffic

2. Export Data

   • Export captured data to CSV/JSON format
   • Generate custom reports from historical data
   • Backup capture sessions for later analysis

Notes

1. Administrator privileges are required to capture network packets.
