NetTool — Network Engineer Toolkit

NetTool is a high-performance, modern desktop utility application designed specifically for network engineers, system administrators, and developers. Built on a cutting-edge stack of React 19, TypeScript, and Electron, it brings together essential diagnostic tools, remote terminals, subnet scanners, and utility engines into a single, unified, and beautiful glassmorphic dark-mode application.

Key Features

Multi-Tabbed Web Terminal

Manage multiple remote connections concurrently using xterm.js terminal emulation:

• SSH Client: Secure Shell shell sessions with custom port, credential options, and support for legacy Diffie-Hellman algorithms.
• Telnet Client: Raw TCP socket sessions with custom Interpret As Command (IAC) option filtering to ensure clean and correct character rendering.
• Serial Port Manager: Connect to hardware interfaces (COM ports) featuring a natural-sorting port list, custom baud rates, and live port auto-refresh.

Ping, Traceroute & Jitter Diagnostics

• Live Latency Analytics: Real-time round-trip latency tracking calculating minimum, maximum, and average times with live packet loss percentages.
• Jitter Verification: Advanced ping variation calculations crucial for VoIP diagnostics and high-stability network validations.
• Traceroute: Live path discovery charting routing hops to destination hosts.

Network Discovery

• Ping Sweep: Fast subnet scanning engine to discover active IP addresses and responsive devices across local networks.

Quick File Servers

Spin up local file-sharing servers instantly with a single click:

• FTP Server: Configurable port, anonymous or credentialed access.
• TFTP Server: Fast file transfer server for firmware upgrades.
• HTTP & HTTPS Servers: Static file servers with support for automatic self-signed SSL certificate generation.

Network Utilities

• Wake-on-LAN: Broadcasts Magic Packets to remote MAC addresses to wake up offline nodes.
• MAC Vendor Query: Identifies hardware manufacturers using MAC address queries.
• DNS Resolver: Performs full DNS record resolution (A, MX, TXT, CNAME, etc.) for specified domains.
• WHOIS Lookup: Queries domain registration records.
• ARP Table Diagnostics: Inspects Address Resolution Protocol mappings.

Integrated Speed Test

• Measurement Engine: Diagnostic speed check measuring latency, download, and upload rates using a parallel HTTP stream architecture connected to Cloudflare infrastructure.

Design & Craftsmanship

The interface has been meticulously designed following advanced design engineering principles:

• Glassmorphic Theme: Sophisticated dark-mode panel transparency using hardware-accelerated backdrop filters.
• Snappy Micro-animations: Custom timing curves (cubic-bezier(0.23, 1, 0.32, 1)) for UI interactions, active button presses (scale(0.97)), and smooth dropdown reveals.
• Mobile/Touch Protection: Touch devices are shielded from "sticky hovers" using fine-pointer media query wrappers.

Technology Stack

• Frontend: React 19 (Hooks, Context, Conditional Rendering), TypeScript, Tailwind CSS, Xterm.js
• Backend: Electron, Node.js, Express, Socket.IO (for real-time communication), SSH2, SerialPort

Getting Started

Prerequisites

• Node.js (v18 or higher)
• npm (Node Package Manager)

Local Development

1. Clone the repository:

   git clone https://github.com/alicicek-dev/network_tool.git
   cd network_tool

2. Install the dependencies:

   npm install

3. Launch the development server and Electron container:

   npm run dev

Production Build

To compile and package the application into standalone Windows installers (NSIS) and portable binaries:

1. Ensure all active NetTool runtime instances are closed.
2. Run the build script:

   npm run build

3. Standalone binaries will be compiled and saved to the release/ directory.
