NDISAPI

Crates.io Documentation License

NDISAPI is a Rust crate for interacting with the Windows Packet Filter driver. It provides an easy-to-use, safe, and efficient interface to efficiently filter (inspect and modify) raw network packets at the NDIS level of the network stack with minimal impact on network activity.

Windows Packet Filter (WinpkFilter) is a high-performance, lightweight packet filtering framework for Windows, enabling developers to efficiently inspect, modify, and control raw network packets at the NDIS level. With user-friendly APIs and support for various Windows versions, WinpkFilter simplifies network packet manipulation without requiring kernel-mode programming expertise.

Features

  • Enumerate network adapters
  • Query and set network adapter properties
  • Capture and analyze packets
  • Filter and modify packets
  • Send raw packets

Dependencies

Installation

Add the following to your Cargo.toml file:

[dependencies]
ndisapi = "0.6.0"

Usage

Here's an example of how to enumerate network adapters and print their information:

use ndisapi::{MacAddress, Ndisapi};

fn main() {
    let ndis = Ndisapi::new("NDISRD").expect("Failed to create NdisApi instance");

    let adapters = ndis
        .get_tcpip_bound_adapters_info()
        .expect("Failed to enumerate adapters");

    for adapter in adapters {
        println!("Adapter: {:?}", adapter.get_name());
        println!(
            "Description: {:?}",
            Ndisapi::get_friendly_adapter_name(adapter.get_name()).unwrap_or("Unknown".to_string())
        );
        println!(
            "MAC Address: {:?}",
            MacAddress::from_slice(adapter.get_hw_address()).unwrap_or_default()
        );
        println!("-------------------------------");
    }
}

Following is the demonstration of the async-packthru example. For this scenario, we will assume that vEthernet (WLAN Virtual Switch) is the default internet connection

PS D:\github.com\ndisapi-rs> cargo run --example async-packthru -- --interface-index 11
    Finished dev [unoptimized + debuginfo] target(s) in 0.11s
     Running `target\debug\examples\async-packthru.exe --interface-index 11`
