ICMPWatch – Advanced Sniffing & Analysis of ICMP Packets

ICMP Packet Sniffer is a Python program that allows you to capture and analyze ICMP (Internet Control Message Protocol) packets on a network interface.

It provides detailed information about the captured packets, including source and destination IP addresses, MAC addresses, ICMP type, payload data, and more.

The program can also store the captured packets in a SQLite database and save them in pcap format.

Features

  • Capture and analyze ICMP Echo Request and Echo Reply packets.
  • Display detailed information about each ICMP packet, including source and destination IP addresses, MAC addresses, packet size, ICMP type, and payload content.
  • Save captured packet information to a text file.
  • Store captured packet information in an SQLite database.
  • Save captured packets to a PCAP file for further analysis.
  • Support for custom packet filtering based on source and destination IP addresses
  • Colorful console output using ANSI escape codes.
  • User-friendly command-line interface.

Requirements

  • Python 3.7+
  • scapy 2.4.5 or higher
  • colorama 0.4.4 or higher

Installation

  1. Clone this repository:
git clone https://github.com/HalilDeniz/ICMPWatch.git

2. Install the required dependencies:

pip install -r requirements.txt

Usage

python ICMPWatch.py [-h] [-v] [-t TIMEOUT] [-f FILTER] [-o OUTPUT] [--type {0,8}] [--src-ip SRC_IP] [--dst-ip DST_IP] -i INTERFACE [-db] [-c CAPTURE]
  • -v or --verbose: Show verbose packet details.
  • -t or --timeoutsniffing timeout in seconds (default is 300 seconds).
  • -f or --filtera BPF filter for packet sniffing (default is “icmp”).
  • -o or --outputan Output file to save captured packets.
  • --type: ICMP packet type to filter (0: Echo Reply, 8: Echo Request).
  • --src-ipsource IP address to filter.
  • --dst-ipdestination IP address to filter.
  • -i or --interfacea Network interface to capture packets (required).
  • -db or --databasestore captured packets in an SQLite database.
  • -c or --capturea Capture file to save packets in pcap format.

Press Ctrl+C to stop the sniffing process.

Examples

  • Capture ICMP packets on the “eth0” interface:
python icmpwatch.py -i eth0
  • Sniff ICMP traffic on interface “eth0” and save the results to a file:
python dnssnif.py -i eth0 -o icmp_results.txt
  • Filtering by Source and Destination IP:
python icmpwatch.py -i eth0 --src-ip 192.168.1.10 --dst-ip 192.168.1.20
  • Filtering ICMP Echo Requests:
python icmpwatch.py -i eth0 --type 8
  • Saving Captured Packets
python icmpwatch.py -i eth0 -c captured_packets.pcap
