NetFlow Generator

This project simulates and generates NetFlow data in pcap file, typically used for network monitoring and analysis.

Setup Instructions

1. Clone the repository:

   git clone https://github.com/GavinITP/netflow-generator.git
   cd netflow-generator

2. Compile the code:

   clang++ -std=c++20 -O3 main.cpp netflow.cpp utils.cpp -o netflow_pcap_writer

   or

   g++ -std=c++20 -O3 main.cpp netflow.cpp utils.cpp -o netflow_pcap_writer

3. Run the program:

   ./netflow_pcap_writer

Code Overview

• main.cpp: Generate raw packets with NetFlow data and writing them to a .pcap file.
• netflow.cpp: Contains the logic to generate and serialize NetFlow data.
• utils.cpp: Provides utility functions like generating random numbers and converting IP addresses to uint32_t.
