# VirtualDDNSRouter (VDR)
|
||||
|
||||
VirtualDDNSRouter (VDR) is a lightweight dynamic DNS router solution that consists of two components:
|
||||
- **Client**: Updates the server with the current IP address of a service
|
||||
- **Server**: Acts as a reverse proxy that redirects requests to the correct IP address
|
||||
|
||||
This solution is particularly useful for accessing services running on dynamic IP addresses through consistent URLs.
|
||||
|
||||
## Quick Start (Recommended Method)
|
||||
|
||||
The easiest way to use VDR is by downloading the pre-built binaries:
|
||||
|
||||
1. Download the latest release for your platform from [https://git.mahdium.ir/mahdium/VDR/releases/latest](https://git.mahdium.ir/mahdium/VDR/releases/latest)
|
||||
2. Extract the archives for both client and server
|
||||
3. Configure each component using the provided examples
|
||||
4. Run the server and client applications
|
||||
|
||||
## Components
|
||||
|
||||
- [Client Documentation](VirtualDDNSRouter.Client/README.md) - For updating IP addresses
|
||||
- [Server Documentation](VirtualDDNSRouter.Server/README.md) - For routing requests
|
||||
|
||||

```
|
||||
|
||||
## Alternative Deployment Methods
|
||||
|
||||
### Using Docker
|
||||
|
||||
You can also run VDR using Docker:
|
||||
|
||||
```bash
|
||||
# Build the images
|
||||
docker-compose build
|
||||
|
||||
# Run the services
|
||||
docker-compose up
|
||||
```
|
||||
|
||||
See the [compose.yaml](compose.yaml) file for details.
|
||||
|
||||
### Building from Source
|
||||
|
||||
If you prefer to build from source:
|
||||
|
||||
```bash
|
||||
# For the server
|
||||
cd VirtualDDNSRouter.Server
|
||||
dotnet build
|
||||
dotnet run
|
||||
|
||||
# For the client
|
||||
cd VirtualDDNSRouter.Client
|
||||
dotnet build
|
||||
dotnet run
|
||||
```

# VirtualDDNSRouter Client
|
||||
|
||||
The VirtualDDNSRouter Client is a lightweight application that periodically updates the IP address of a service with the VirtualDDNSRouter Server.
|
||||
|
||||
## Configuration
|
||||
|
||||
The client uses a YAML configuration file named `settings.yaml`. You can create this file by copying and modifying the provided example:
|
||||
|
||||
```bash
|
||||
cp settings.example.yaml settings.yaml
|
||||
```
|
||||
|
||||
The configuration file has the following structure:
|
||||
|
||||
```yaml
|
||||
host: example.com # The hostname of the VDR server
|
||||
path: odoo # The path identifier for your service
|
||||
destination_port: 8081 # The port of your service
|
||||
api_key: abc123XYZ # The API key for authentication
|
||||
refresh_interval_minutes: 3 # How often to update the IP address (in minutes)
|
||||
```
|
||||
|
||||
## Running the Client
|
||||
|
||||
### Method 1: Downloading Pre-built Binaries (Recommended)
|
||||
|
||||
1. Download the latest client binary from [https://git.mahdium.ir/mahdium/VDR/releases/latest](https://git.mahdium.ir/mahdium/VDR/releases/latest)
|
||||
2. Extract the archive
|
||||
3. Create your `settings.yaml` file based on `settings.example.yaml`
|
||||
4. Run the client:
|
||||
|
||||
```bash
|
||||
./VirtualDDNSRouter.Client
|
||||
```
|
||||
|
||||
### Method 2: Using Docker
|
||||
|
||||
```bash
|
||||
docker run -v ./settings.yaml:/app/settings.yaml virtualddnsrouter.client
|
||||
```
|
||||
|
||||
### Method 3: Building from Source
|
||||
|
||||
```bash
|
||||
dotnet build
|
||||
dotnet run
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
After starting the client, it will:
|
||||
1. Read the configuration from `settings.yaml`
|
||||
2. Send an update to the server every `refresh_interval_minutes`
|
||||
3. Continue running until stopped with Ctrl+C
|
||||
|
||||
The client will output logs showing when updates are sent and whether they were successful.

# VirtualDDNSRouter Server
|
||||
|
||||
The VirtualDDNSRouter Server is a lightweight reverse proxy that maintains dynamic mappings between paths and IP addresses. Clients can update their IP addresses, and users can access services through consistent URLs.
|
||||
|
||||
## Configuration
|
||||
|
||||
The server uses a YAML rules file named `rules.yaml`. You can create this file by copying and modifying the provided example:
|
||||
|
||||
```bash
|
||||
cp rules.example.yaml rules.yaml
|
||||
```
|
||||
|
||||
The rules file has the following structure:
|
||||
|
||||
```yaml
|
||||
- name: Odoo Server # A descriptive name for the service
|
||||
api_key: abc123XYZ # The API key for authentication
|
||||
path: odoo # The path identifier for the service
|
||||
|
||||
- name: Backup server
|
||||
api_key: def456ABC
|
||||
path: bk
|
||||
```
|
||||
|
||||
Each entry defines a service with:
|
||||
- `name`: A descriptive label (for documentation purposes)
|
||||
- `api_key`: A secret key used by clients to authenticate updates
|
||||
- `path`: The URL path that users will use to access the service
|
||||
|
||||
## Running the Server
|
||||
|
||||
### Method 1: Downloading Pre-built Binaries (Recommended)
|
||||
|
||||
1. Download the latest server binary from [https://git.mahdium.ir/mahdium/VDR/releases/latest](https://git.mahdium.ir/mahdium/VDR/releases/latest)
|
||||
2. Extract the archive
|
||||
3. Create your `rules.yaml` file based on `rules.example.yaml`
|
||||
4. Run the server:
|
||||
|
||||
```bash
|
||||
./VirtualDDNSRouter.Server
|
||||
```
|
||||
|
||||
By default, the server listens on port 8080. You can change this by setting the `ASPNETCORE_HTTP_PORTS` environment variable:
|
||||
|
||||
```bash
|
||||
ASPNETCORE_HTTP_PORTS=8081 ./VirtualDDNSRouter.Server
|
||||
```
|
||||
|
||||
### Method 2: Using Docker
|
||||
|
||||
```bash
|
||||
docker run -p 8080:8080 -v ./rules.yaml:/app/rules.yaml virtualddnsrouter.server
|
||||
```
|
||||
|
||||
### Method 3: Building from Source
|
||||
|
||||
```bash
|
||||
dotnet build
|
||||
dotnet run
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
The server provides two main endpoints:
|
||||
|
||||
1. **IP Update Endpoint** (used by clients):
|
||||
```
|
||||
GET /setip/{path}/{port}/{api_key}
|
||||
```
|
||||
Clients call this endpoint to update their IP address.
|
||||
|
||||
2. **Service Access Endpoint** (used by users):
|
||||
```
|
||||
GET /goto/{path}
|
||||
```
|
||||
Users access this endpoint to reach the service associated with the path.
|
||||
|
||||
For example, if a client has configured a service with path "odoo", users can access it at:
|
||||
```
|
||||
http://your-server:8080/goto/odoo
|
||||
```
|
||||
|
||||
The server will redirect users to the IP address and port that the client last reported.
