Enviro6 - IPv6 DHCP & DNS Server Configuration Tool and Sniffing Tool

This tool is designed to automatically set up and configure a Linux-based server (e.g., Kali Linux) as an IPv6 DHCP, DNS, and Router Advertisement Daemon (RADVD) server. The script facilitates the deployment of a fully functional IPv6 environment, where the server can act as the default gateway, DNS server, and DHCPv6 server for the network clients.

Key Features

• DHCPv6: Automatically set up a DHCPv6 server with a unique ULA (Unique Local Address) to assign IPv6 addresses to devices on the network.
• DNS: Configure a DNS server that maps domains to IPv6 and IPv4 addresses as specified by the user.
• Router Advertisement (RA): Broadcast router advertisements in the network to inform devices about router addresses and other configurations.
• Sniffing: Monitor and listen to Neighbor Discovery Protocol (NDP) activity in the network.
• Restore: Restore network settings to their previous state before any changes were made by the tool.

Installation

The tool is Python-based and requires a few dependencies to be installed on a Kali Linux environment.

1. Clone the repository:

   python3 -m venv Enviro6
   Source Enviro6/bin/active
   cd Enviro6
   git clone https://github.com/ShkudW/Enviro6.git
   cd Enviro6

2. Install the necessary dependencies:

   sudo apt-get update
   sudo apt-get install isc-dhcp-server dnsmasq radvd python3-pip netplan
   pip3 install colorama

Examples

• Setting up DHCPv6 and DNSv6:

  python3 Enviro6.py -iface <eth0> -dns -domain <example.co.il>

• Sniffing NDP traffic:

  python3 Enviro6.py -iface <eth0> -sniff

• Restoring configurations:

  python3 Enviro6.py -restore
