Pluto is a Windows Server VM on Jupiter. It is the **general-purpose Windows build machine** for any project needing a native Windows executable — not just GuruRMM.

- **Hostname:** PLUTO (VM on Jupiter)
- **Static IP:** 172.16.3.36 (confirmed static 2026-04-19)
- **SSH:** `ssh -i ~/.ssh/id_ed25519 Administrator@172.16.3.36` (key auth)
- **Authorized keys (verified via RMM 2026-05-26):** `gururmm-build@gururmm-server` and `guru@gururmm-build` (the build server's keys), present in both `C:\ProgramData\ssh\administrators_authorized_keys` and `Administrator\.ssh\authorized_keys`. The old `guru@DESKTOP-0O8A1RL` key (retired machine) has already been rotated out. NOTE: no personal-workstation key (e.g. GURU-5070) is currently authorized — the `ssh -i ~/.ssh/id_ed25519 Administrator@172.16.3.36` workflow below works only from a host whose pubkey is in the file; add GURU-5070's pubkey to `administrators_authorized_keys` if you need direct workstation SSH.

## Installed Toolchain

- **Rust:** stable-x86_64-pc-windows-msvc (rustup at `C:\Users\Administrator\.cargo\bin`)
- **VS Build Tools:** Installed with `Microsoft.VisualStudio.Workload.VCTools` (MSVC linker, CRT, Windows SDK)
- **Git:** v2.47.1.windows.2
- **OpenSSH:** Win32-OpenSSH, sshd set to Automatic startup

## Use Cases

Use Pluto when you need a **native Windows MSVC build** — produces proper `.exe` files with no MinGW runtime dependency. Examples:
- Utilities (internal tooling, one-off scripts compiled to EXE)
- Howard's tech tools (MasterBooter, Slint GUI apps, etc.)
- GuruRMM agent MSVC builds (when MSVC target is preferred over the automated MinGW build on the Linux server)
- Anything using Windows-only APIs or needing code signing via signtool

**Note:** Routine GuruRMM agent builds are automated on the Linux server (172.16.3.30) via MinGW + jsign. Use Pluto for MSVC-specific builds or one-off tooling.

## Directory Layout

- `C:\builds\` — general project builds (create a subdirectory per project)
- `C:\gururmm\` — GuruRMM repo clone

## Typical Build Workflow

```bash
# 1. SSH in
ssh -i ~/.ssh/id_ed25519 Administrator@172.16.3.36

# 2. Clone or pull project
git clone https://azcomputerguru:<token>@git.azcomputerguru.com/azcomputerguru/<repo>.git C:\builds\<project>

# 3. Build
cd C:\builds\<project>
cargo build --release

# 4. SCP output back
# From workstation:
scp -i ~/.ssh/id_ed25519 Administrator@172.16.3.36:"C:/builds/<project>/target/release/<name>.exe" ./
```

## Not Neptune

Neptune is a separate existing server (email/web hosting). Pluto is only for builds.
