net_sentinel_shield - NetSentinel Shield: A high-performance, Rust-based

项目说明

NetSentinel Shield

NetSentinel Shield is a high-performance, command-line security tool written in Rust. It allows users to manage network security by blocking access to specified domains at the operating system level via the hosts file.

Features

System-le: Effectively blocks websites across all browsers and system applications.

Non-Destructive: Uses custom markers to ensure it only manages the domains you add, leaving the rest of your hosts file untouched.

High Performance: Lightweight and optimized using Rust for fast execution.

Installation

Ensure you have Rust installed on your system.

Clone the repository:

Build the project in release mode:

You can find the executable in target/release/net_sentinel_shield.exe.

Usage

Important: This application modifies system files (hosts). You must run your terminal or command prompt as an Administrator for the tool to function correctly.

1. Preparing your blocklist
Create a simple text file (e.g., domains.txt) and list the domains you wish to block, one per line:

facebook.com

www.facebook.com

instagram.com

www.instagram.com

chess.com

www.chess.com

monkeytype.com

www.monkeytype.com

2. Blocking Domains
To block the domains listed in your text file, run:

3. Restoring Access
To remove the blocked domains and restore your hosts file to its original state, run:

Troubleshooting

Permissions: Always run your terminal as Administrator.

Browser Caching: If a blocked site still loads, please clear your browser's DNS cache:

In Chrome/Yandex/Edge, na to chrome://net-internals/#dns and click "Clear host cache".

Alternatively, run ipconfig /flushdns in an Administrator Command Prompt.

Secure DNS: If you use "Secure DNS" (DNS o) in your browser settings, the hosts file might be bypassed. Consider disabling it for local blocking to work reliably.
