# 🌐 Wireless Network Analyzer/ Network Packet Sniffer

A C++ program that captures and analyzes network packets using the libpcap library. This tool displays packet information including timestamps, packet length, and MAC addresses.

## ✨ Features

- 📡 Real-time packet capture

- 🔍 MAC address extraction and formatting

- ⏱️ Packet timestamp logging

- 📊 Packet size analysis

- 🔄 Continuous packet monitoring

## 📋 Prerequisites

- 🖥️ Linux/Unix Operating System

- ⚡ GCC/G++ Compiler

- 📦 libpcap-dev package

- 👑 Root/Administrative privileges

## 🚀 Installation

1. Install libpcap development package:

```bash

sudo apt-get install libpcap-dev

```

2. Clone this repository:

```bash

git clone https://github.com/ybigsur5/packet-sniffer.git

```

3. Compile the program:

```bash

g++ packet_sniffer.cpp -o packet_sniffer -lpcap

```

## 💻 Usage

1. Run the program with root privileges:

```bash

sudo ./packet_sniffer

```

The program will:

- 🔍 Automatically detect network interface

- 📡 Start capturing packets

- 📊 Display packet information in real-time

- 🔄 Continue until manually stopped (Ctrl+C)

## 📝 Output Format

For each captured packet, the program displays:

```

Packet captured!

Timestamp: [seconds].[microseconds]

Packet length: [length] bytes

Source MAC: xx:xx:xx:xx:xx:xx

Dest MAC: xx:xx:xx:xx:xx:xx

```

## ⚠️ Limitations

- 👑 Requires root privileges

- 🐧 Linux/Unix systems only

- 🔌 Depends on libpcap library

## 🔒 Security Considerations

- ⚠️ Only run on networks you have permission to monitor

- 🛡️ Be aware of privacy and legal implications

- 🔐 Handle captured data responsibly

## 🚀 Future Enhancements

1. Add protocol analysis (TCP/IP, UDP)

2. Implement packet filtering

3. Add packet payload inspection

4. Create packet statistics

5. Add GUI interface
