🔴 ICMP Packet Sender Tool

📌 Overview

This project is a Python-based interactive tool that uses Scapy to create and send custom ICMP (ping) packets. It allows you to define the source IP, destination IP, and ICMP ID, then sends the crafted packet and displays the response if one is received.
This makes it useful for:

• Learning how ICMP works
• Debugging networks
• Security testing in controlled environments

---

⚙️ Features

• Interactive mode:
  • Enter Source IP (spoofing possible if allowed)
  • Enter Destination IP
  • Enter ICMP ID
• Sends ICMP Echo Request and waits for a reply
• Displays response details using Scapy’s .show()
• Graceful error handling
• Loop option (send multiple packets in one run)

---

🚀 Usage

1️⃣ Create & activate a virtual environment

python -m venv venv
source venv/bin/activate # Linux / Mac
venv\Scripts\activate # Windows

---

2️⃣ Install Scapy in the virtual environment

pip install scapy

---

3️⃣ Run the tool

python icmp.py

---

🛠️ Example Session

$ python icmp.py

src ip > 192.168.1.10

dst ip > www.google.com

icmp id > 123

Response packet will be displayed if received

Continue? (y/n) > y

If there is a reply, you’ll see packet details printed (IP/ICMP headers and more). If no reply is received, you’ll see:

No response received.

📄 Requirements
