Analyze DNS traffic with EchoDNS

EchoDNS is a powerful tool designed to analyze DNS traffic by acting as a DNS server, intercepting and forwarding requests to a real DNS server of your choice without being detected. It offers a multithreading feature to process requests more efficiently, and a built-in garbage collector automatically cleans up stuck threads, ensuring optimal performance.

Features

• Intercept and analyze DNS traffic
• Forward DNS packets to a real DNS server (default: Google DNS)
• Efficient multithreading for improved performance
• Automatic thread cleanup using a built-in garbage collector
• Command-line configuration for customizing various parameters

Prerequisites

• sudo (admin) privileges: EchoDNS requires administrative privileges to operate effectively because port 53 is usually reserved. You need root permission to use that port.

Getting Started

Follow these simple steps to get started with EchoDNS:

1. Clone this repository to your local machine.
2. Ensure you have Python 3+ installed (link to Python installation guide).
3. Install the required dependencies using pip:

pip install -r requirements.txt

4. Modify the configuration using command-line arguments:

usage: echodns.py [-h] [-d DNS] [-t THREADS] [-a AGE] [-p PORT] [-i IP] [-l LOG_SIZE]

optional arguments:
  -h, --help            show this help message and exit
  -d DNS, --dns DNS     DNS server to forward requests to (default: Google DNS)
  -t THREADS, --threads THREADS
                        Max amount of threads (default: 100)
  -a AGE, --age AGE     Max age of thread in seconds (default: None)
  -p PORT, --port PORT  Local port to listen (default: 53)
  -i IP, --ip IP        Local IP to listen (default: 127.0.0.1)
  -l LOG_SIZE, --log-size LOG_SIZE
                        Max size of log in KB (default: 100KB)

5. Run the EchoDNS script with sudo privileges and customize the parameters as needed:

sudo python echodns.py -d 8.8.8.8 -t 200 -a 3 -p 53 -i 192.168.1.10 -l 512000

Example output:

Filter your output with grep

If you are using Linux (or anything else with grep), just pipe the output through it to filter for an explicit domain.

sudo python3 echodns.py | grep google.com
