build.bat was broken by the contract extraction: it staged the loose Launcher .cs files into temp folders and published from there, but the projects now have a ProjectReference to ..\Contract\Tesla.Contract.csproj which cannot resolve from a temp dir. Publish the projects IN PLACE instead, and target net8 / win-x64 (self-contained single-file) to match the runtime/arch uplift. The resulting TeslaLauncher\ package (Service\ + Agent\ + install.bat) installs on a pod with no .NET runtime prerequisite. - Launcher/README.md: correct net6->net8, x86->x64, BinaryFormatter->framed JSON, and note wire types now come from ../Contract. - Launcher/.gitignore: ignore the TeslaLauncher-*.zip deployment package. - Console/.gitignore: ignore the published TeslaConsole-app\ package + its zip (framework-dependent net48 console build for running against a test pod).

# TeslaLauncher
|
|
|
|
.NET 8 (win-x64, self-contained) rewrite of the original Elsewhen Studios LLC software (Windows 2000 / .NET Framework 2.0).
|
|
|
|
## Architecture
|
|
|
|
TeslaLauncher has three components that work together:
|
|
|
|
### TeslaLauncherService (Windows Service, Session 0)
|
|
- Runs at boot before any user logs in
|
|
- Listens on **TCP 53290** for OFB-encrypted framed-JSON RPC from TeslaConsole
|
|
- Forwards commands to the Agent via Named Pipe (`TeslaLauncherIPC`)
|
|
- Handles first-boot network configuration (SecureConfig)
|
|
- Handles game file transfers from the Console (InstallProduct)
|
|
|
|
### TeslaLauncherAgent (WinForms tray app, user session)
|
|
- Runs in the logged-in user's desktop session
|
|
- Executes commands that require desktop access: launching/killing apps, volume control
|
|
- Manages `LaunchApps.xml` (installed games registry)
|
|
- On first boot, displays SecureConfig Request ID and Passphrase
|
|
|
|
### SecureConfig (first-boot protocol)
|
|
- Assigns a temporary IP and broadcasts a UDP beacon so the Console can discover the pod
|
|
- Operator reads the Passphrase off the pod screen and enters it into the Console
|
|
- Console sends AES-encrypted network configuration (IP, mask, gateway, DNS, hostname)
|
|
- TCP handshake establishes an OFB-encrypted session with RSA key exchange
|
|
- Session key is saved for all subsequent Console connections
|
|
|
|
## Communication Flow
|
|
|
|
```
|
|

## Files
|
|
|
|
| File | Description |
|
|
|------|-------------|
|
|
| `TeslaLauncherService.cs` | Windows Service implementation |
|
|
| `TeslaLauncherService.csproj` | Service project (net8.0-windows, x64, self-contained) |
|
|
| `TeslaLauncherAgent.cs` | Userspace Agent implementation |
|
|
| `TeslaLauncherAgent.csproj` | Agent project (WinForms, net8.0-windows, x64) |
|
|
| `LaunchModels_Shared.cs` | Service↔Agent IPC types (Tesla.Launcher.Shared). Wire types (Tesla.Net) now come from `../Contract/Tesla.Contract.csproj` |
|
|
| `SecureConfig.cs` | First-boot secure configuration protocol |
|
|
| `build.bat` | Builds both components |
|
|
| `install.bat` | Installs on a cockpit PC (run as Administrator) |
|
|
|
|
## Building
|
|
|
|
Requirements:
|
|
- .NET 8 SDK
|
|
- Internet access for NuGet restore (first build only)
|
|
|
|
```
|
|
build.bat :: build both components + assemble the package
|
|
build.bat /service :: build Service only
|
|
build.bat /agent :: build Agent only
|
|
```
|
|
|
|
Output goes to `TeslaLauncher\` with `Service\` and `Agent\` subdirectories plus
|
|
`install.bat`. The projects are published in place (self-contained, single-file,
|
|
win-x64) — they reference `../Contract`, so they cannot be staged into a temp
|
|
folder. No .NET runtime is required on the target pod.
|
|
|
|
## Installation
|
|
|
|
1. Copy the `TeslaLauncher\` folder to each cockpit PC
|
|
2. Run `TeslaLauncher\install.bat` as Administrator
|
|
|
|
The installer:
|
|
- Registers the Service (delayed auto-start)
|
|
- Configures the Agent for auto-login startup
|
|
- Installs OpenAL and DirectX runtimes
|
|
- Enables SMB1 file sharing
|
|
- Creates `C:\Games` with appropriate permissions
|
|
- Resets network adapters to DHCP for SecureConfig
|
|
|
|
## First Boot
|
|
|
|
1. Cockpit boots with DHCP (unconfigured state)
|
|
2. Service runs SecureConfig: broadcasts beacon, displays codes on screen
|
|
3. Console operator sees the pod's Request ID and enters the Passphrase
|
|
4. Console sends encrypted network configuration
|
|
5. Pod applies the configuration and is ready for normal operation
|
|
|
|
## Normal Operation
|
|
|
|
The Console connects to each configured pod on TCP 53290 and can:
|
|
- Install/uninstall simulation games
|
|
- Launch/kill applications
|
|
- Get/set volume level
|
|
- Query pod status (FullUpdate)
|
|
- Shutdown or reboot the pod
|
|
|
|
## Key Paths
|
|
|
|
| Path | Purpose |
|
|
|------|---------|
|
|
| `C:\ProgramData\TeslaLauncher\TeslaKeyStore.key` | Session key (32 bytes) |
|
|
| `C:\ProgramData\TeslaLauncher\LaunchApps.xml` | Installed games registry |
|
|
| `C:\ProgramData\TeslaLauncher\configuring.json` | Transient: SecureConfig codes for Agent display |
|
|
| `C:\Games\` | Game installation directory |
|
|
|
|
## Wire Protocol
|
|
|
|
The Console talks to the Service with **length-prefixed System.Text.Json frames**
|
|
over the OFB-encrypted TCP stream (dispatch by method name) — see
|
|
`../Contract/PodRpcProtocol.cs`, shared by both ends. This replaced the original
|
|
`BinaryFormatter` + serialized-`MethodBase` scheme. The `Tesla.Net` wire types now
|
|
live in `../Contract/Tesla.Contract.csproj`, the single source of truth shared with
|
|
the Console.
|
|
|
|
The Service-to-Agent IPC uses length-prefixed JSON over a Named Pipe, with flat types
|
|
that avoid the nested struct layout of the wire format.
