Features

Basic Diagnostics

• Advanced ping testing with detailed statistics
• Multi-type port scanning (SYN, UDP, Connect, FIN, XMAS, NULL)
• Comprehensive DNS resolution with multiple record types
• Network speed testing with server selection
• Traceroute analysis
• Advanced SSL certificate checking

Advanced Features

• Network interface monitoring and statistics
• Real-time packet analysis and sniffing
• WHOIS information lookup
• Detailed network interface information
• Colored output for better readability
• Report generation and export
• Concurrent operations support
• Detailed logging

Prerequisites

• Python 3.6 or higher
• Linux operating system
• Root privileges for some operations (like port scanning and packet sniffing)
• Required system packages:

  sudo apt-get install python3-scapy
  sudo apt-get install traceroute

Installation

1. Clone this repository or download the files:

   git clone <repository-url>
   cd <repository-directory>

2. Install the required dependencies:

   pip install -r requirements.txt

Usage

The tool can be used with various command-line arguments:

python network_diagnostics.py [options]

Options

• --host <hostname>: Target host to diagnose (e.g., example.com or 192.168.1.1)
• --domain <domain>: Domain for DNS lookup and SSL certificate check
• --interface <interface>: Network interface to monitor (e.g., eth0, wlan0)
• --speed: Run network speed test
• --scan-type <type>: Port scan type (SYN, UDP, Connect, FIN, XMAS, NULL)
• --duration <seconds>: Duration for interface monitoring (default: 10)
• --all: Run all available diagnostics
• --output <file>: Save the report to a file

Examples

1. Run all diagnostics on a specific host with custom scan type:

   python network_diagnostics.py --host example.com --scan-type SYN,UDP --all

2. Monitor network interface and analyze packets:

   python network_diagnostics.py --interface eth0 --duration 30

3. Check domain information and SSL certificate:

   python network_diagnostics.py --domain example.com --output report.txt

4. Run speed test and save results:

   python network_diagnostics.py --speed --output speed_report.txt

Data Structure

Advanced Features

Network Interface Monitoring

• Real-time monitoring of network interface statistics
• Packet counts and byte statistics
• Interface status and MTU information

Packet Analysis

• Capture and analyze network packets
• Source and destination IP tracking
• Protocol analysis
• Packet size statistics
