## Introduction
NetAssistant is a high-performance, modern network debugging tool built with Rust. It provides an intuitive interface for testing and debugging network communications, supporting TCP/UDP client and server modes.
## ✨ Features
- **Multi-protocol support**: TCP/UDP client and server modes
- **Chat-style message logging**: Intuitive display of message interactions
- **Configuration persistence**: Automatically saves connection configurations
- **Auto-reply functionality**: Supports test auto-replies
- **Periodic send functionality**: Supports timed periodic message sending
- **Multi-tab management**: Manage multiple connections simultaneously
- **Client message viewing**: Select specific clients to view their messages
## 📸 Interface Preview
### Client Mode
### Server Mode
## 🚀 Quick Start
### Prerequisites
- Rust 1.70 or higher
- Windows 10/11 or Linux
### Installation
#### Recommended Method: Install via winget
**Advantages**: Supports automatic upgrades, easier installation and management
1. First install winget (built-in on Windows 10 1809+ or Windows 11, or refer to [Microsoft official documentation](https://learn.microsoft.com/en-us/windows/package-manager/winget/) for installation methods)
2. Open Command Prompt or PowerShell and run:
```bash
winget install SunJary.NetAssistant
```
3. To upgrade later, simply run:
```bash
winget upgrade SunJary.NetAssistant
```
#### Alternative Method: Download from GitHub Release
Please visit the [GitHub Release page](https://github.com/sunjary/netassistant/releases) to download the latest version.
### Running
After downloading, extract the package and run the executable file.
## 💡 Usage
1. **Create Connection**
- Click the `[+New]` button in the left panel
- Select connection type (Client/Server)
- Select protocol (TCP/UDP)
- Fill in address and port
2. **Connect to Server**
- For client connections, click the `[Connect]` button
- For server connections, click the `[Start]` button
3. **Send Messages**
- Enter message content in the bottom input box
- Click the `[Send]` button or press Enter to send
4. **Periodic Send**
- Enable periodic send functionality in the connection tab
- Set send interval (milliseconds)
- Click the `[Send]` button to start periodic sending
- Uncheck periodic send to stop the sending task
5. **Auto-reply**
- Enable auto-reply functionality in the connection tab
- Set auto-reply content
- Auto-reply when receiving messages
6. **Manage Connections**
- Use tabs to switch between different connections
- Click the `×` on the tab to close the connection
- Right-click on the connection to delete saved configuration
7. **Client Message Viewing**
- In server mode, the left panel displays the list of connected clients
- Click a single client address to select it, and the right message list will only show messages from that client
- Click the selected client again to deselect and restore all messages
- Server replies to the client will also be included in the viewing results
