# Server Management Tool

This is a simple Go application designed to manage your servers, providing functionalities to list, wake up (Wake-on-LAN), shut down, and reboot them. It offers both a command-line interface (CLI) and a web-based interface for convenient management.

## Features

- **Server Dashboard:** A responsive table view displaying all servers with real-time status, IP, and MAC addresses.
- **Web Terminal:** Integrated xterm.js terminal for direct SSH access to your servers from the browser.
- **Manage Power:**
  - **Wake-on-LAN:** Send magic packets to wake up offline servers.
  - **Shutdown/Reboot:** Gracefully restart or power off servers via SSH.
- **Status Monitoring:** Reliable active health checks (ICMP ping) compatible with macOS and Linux.
- **Server Management:** Add, edit, or remove servers directly from the UI.
- **MAC Address Lookup:** Automatically discover MAC addresses for local servers.

## Prerequisites

- [Go (1.24 or newer)](https://golang.org/doc/install)
- [Docker](https://docs.docker.com/get-docker/)
- `git`

## Getting Started (Local)

1.  **Clone the repository:**

    ```bash
    git clone git@git.hnrx.net:hnrx/manage-servers.git
    cd manage-servers
    ```

2.  **Run the application:**

    ```bash
    go run . serve
    ```

    The application will automatically create a configuration file (`servers.yaml` used by Viper) if one doesn't exist.
    Access the web interface at `http://localhost:8080`.

## Getting Started (Docker)

The project uses standard Docker Hub images (`golang:latest` and `alpine:latest`).

1.  **Build the image:**

    ```bash
    docker build -t manage-servers:latest .
    ```

2.  **Run the container:**

    For Wake-on-LAN to broadcast correctly, the container **must** run in host networking mode:

    ```bash
    docker run -d \
      --name manage-servers \
      --network host \
       manage-servers:latest
    ```

    _Note: Port mapping (`-p 8080:8080`) is not required when using `--network host` as the container shares the host's networking stack._

## Configuration

Servers can be managed entirely through the web UI ("Register Server" button).
Under the hood, the application persists configuration to `config.yaml` or `servers.json` depending on the environment.

### Required Fields for Full Functionality

- **Wake-on-LAN**: Requires valid `MAC Address`.
- **Shutdown/Reboot**: Requires `SSH User` and `SSH Password`.
- **Terminal**: Requires `SSH User` and `SSH Password`.
