# GuruRMM

## Summary

GuruRMM is a Remote Monitoring & Management platform built by Arizona Computer Guru LLC for internal MSP operations and eventual productization. The server (Rust/Axum) and dashboard (React/TypeScript) are production-deployed at https://rmm.azcomputerguru.com with approximately 55 enrolled agents across multiple client sites. The agent runs on managed Windows, Linux, and macOS endpoints.

**Current version:** 0.6.38 (as of 2026-05-24; fleet converged within ~10 minutes of publish)

**Repo:** `azcomputerguru/gururmm` on Gitea (internal: http://172.16.3.20:3000). The copy at `D:\claudetools\projects\msp-tools\guru-rmm` is a stale reference submodule — do NOT develop there; all real work happens in the Gitea repo.

**Goal:** Full-featured MSP platform rivaling commercial RMMs, with a companion PSA (GuruPSA, separate future repo) designed as a truly integrated unified system — not bolted-together products.

## Development

### Current Focus

As of 2026-05-24 (v0.6.38):

- **Tray IPC + peer authorization** — Linux tray merged (PR #13+#14). Open: Windows peer authz (#16), logind console-user resolution (#17), macOS tray (#18), subscriber broadcast (#19).
- **Agent self-update hardening** — ProtectSystem=strict needs `ReadWritePaths=/var/log /usr/local/bin /etc/gururmm` and `RuntimeDirectory=gururmm`. Fixed in PR #21.
- **Auto-update reliability** — BB-SERVER and RECEPTIONIST-PC (Cascades) miss dispatch windows due to flaky WebSockets. Re-querying pending updates on reconnect: incomplete as of 2026-05-24.
- **Watchdog alerts UI** — backend complete but `PUT /watchdog-alerts/:id/resolve` and `DELETE /watchdog-alerts/:id` routes missing on server (found in 2026-05-23 audit).
- **MSP360 backup integration** — Phase 1 complete (monitoring, alerts, mapping, storage thresholds). Phase 2 (management) not started.
- **Security audit backlog:** `credentials/:id/reveal` horizontal privilege escalation (HIGH), `internal_err()` raw DB errors at ~130 call sites (HIGH).

### Patterns & Anti-Patterns

**Anti-patterns — never repeat:**

| Pattern | What Went Wrong |
|---|---|
| `useMemo` with stable deps for data-dependent values | queryClient is stable, memo never recomputes after queries resolve. Use `useQuery` instead. |
| CSS variable text colors inside the sidebar | Sidebar bg is hardcoded dark; CSS vars flip in light mode. Use `text-white` explicitly inside sidebar. |
| Deploying without stopping the server first | "text file busy" kernel error. Always `systemctl stop` before `cp`. |
| Building without `DATABASE_URL` | sqlx compile-time macros fail. `DATABASE_URL` is in `/home/guru/.cargo/env`. |
| DB migrations without inserting into `_sqlx_migrations` | Server crashes on start. Must insert SHA-384 checksum manually. |
| WiX MSI builds on Linux | WiX requires `msi.dll`. MSI must be built on Pluto (Windows). |
| Manual builds via SSH | All builds go through `webhook-handler.py`. Never SSH and run `cargo build` + artifact copy manually. |
| TOML/config for agent endpoint or site_id | Server URL compiled into binary, site_id baked into MSI. No runtime config files for these values. |
| `path.find('\\')` in `#[cfg(windows)]` files | Compiles on Linux silently, fails on Pluto MSVC with unterminated char literal. Use `'\\\\'`. |
| `STATUS_BADGE_CLASSES` Record const | Vite/Rollup may optimize away the lookup. Use explicit `getStatusBadgeClass()` if/else function. |
| SSH heredoc for TypeScript edits | Shell strips double-quote characters. Edit locally in submodule, push to Gitea, pull on server. |
| `Restart-Service GuruRMMAgent -Force` in command scripts | Kills agent before it can report result. Commands stay forever `running`. Use scheduled task with delay instead. |
| `sudo -u guru git` in systemd build context | git rejects repo as dubious ownership when running as root on guru-owned repo. Use `safe.directory` config or `sudo -u guru git`. |
| Self-updating running bash script | bash reads line-by-line from disk; replacing mid-execution silently skips remaining blocks. |
| `+1.77` legacy builds without `--ignore-rust-version` | Fail MSRV check after adding `rust-version` to Cargo.toml. Add `--ignore-rust-version` to legacy build lines only. |
| `StrictHostKeyChecking=no` for Pluto SSH | Replaced with pinned known-hosts at `/opt/gururmm/pluto_known_hosts`. MITM would compromise build artifacts. |
| CRLF line endings in migration files | sqlx SHA-384 checksum mismatch causes server crash on start. `.gitattributes` + `core.autocrlf=false` + pre-commit hook prevents this. |
| Dead WebSocket write half | WS write fails, send task dies, receive loop keeps agent in `ConnectedAgents` with dead write half. Commands silently fail. Fix: `tokio::select!` monitoring both tasks. |

**Good patterns:**

- **Platform parity rule** — any agent feature goes on Windows + Linux + macOS in the same commit. If a real implementation isn't feasible, add a working stub + `// TODO(platform): <os> — <reason>`. No silent no-ops.
- **Per-platform last-built-commit tracking** — Linux builds succeed and record progress independently of Windows builds.
- **Holistic feature development** — every feature ships backend + API + dashboard UI + docs together. Backend-only features are rejected.
- **sqlx offline mode** — compile-time query validation requires DB reachable or offline cache present.
- **`RuntimeDirectory=gururmm` in systemd unit** — systemd-native way to give agent writable `/run/gururmm/` for IPC socket.
- **Registry-first path resolution** — read `HKLM:\SOFTWARE\GuruRMM` for install dir, fall back to service PathName, then hardcoded default.
- **`interrupt_running_commands()` at reconnect** — flips all `status='running'` commands for reconnecting agent to `status='interrupted'`.

### Build & Deploy

**CRITICAL: Never trigger builds manually via SSH. All builds go through the webhook pipeline.**

```
Gitea push to main
  -> webhook-handler.py (172.16.3.30:9000, parallel threads per platform)
    -> build-shared.sh   (auto-version bump, git sync — runs once)
    -> build-linux.sh    (cargo build on .30; log: /var/log/gururmm-build-linux.log)
    -> build-windows.sh  (SSH -> Pluto 172.16.3.36 via pinned known-hosts
                          cargo build --release x64 MSVC + i686 MSVC
                          +1.77 legacy builds with --ignore-rust-version
                          WiX MSI build for site-specific base
                          sign-windows.sh (jsign + Azure Trusted Signing)
                          SCP artifacts back; log: /var/log/gururmm-build-windows.log)
    -> build-mac.sh      (stub — no build machine configured yet)
  -> artifacts -> /var/www/gururmm/downloads/ with sha256 + -latest symlinks
  -> per-platform last-built-commit files updated
  -> systemctl restart gururmm-agent (local agent on .30)
```

**Auto-version:** `build-shared.sh` diffs `agent/`, `server/`, `dashboard/` against last built SHA. For each changed component, bumps patch version in `Cargo.toml` or `package.json`, commits `[ci-version-bump]`, pushes. Webhook skips builds where all commits are version bumps.

**Server code changes** — separate manual step, NOT in agent pipeline:
```bash
sudo /opt/gururmm/build-server.sh
```

**Dashboard deploy** — also separate:
```bash
cd /home/guru/gururmm/dashboard && sudo -u guru npm run build
sudo rsync -av --delete /home/guru/gururmm/dashboard/dist/ /var/www/gururmm/dashboard/
```

**DB migrations** — manual; must insert SHA-384 checksum into `_sqlx_migrations` or server crashes on start.

**Pluto (172.16.3.36):**
- Windows Server 2019 VM on Jupiter (Unraid)
- SSH: `ssh -o UserKnownHostsFile=/opt/gururmm/pluto_known_hosts Administrator@172.16.3.36`
- Rust stable 1.95.0 + 1.77 pinned for legacy builds
- VS Build Tools (MSVC), sccache at `C:\sccache`, WiX v4, Gitea clone at `C:\gururmm\`

**Auto-update delivery:**
- Server scans every 300s; dispatches update command on agent heartbeat
- Gated on effective policy `auto_update` (default on when policy is null)
- Agent: downloads to PrivateTmp, verifies SHA-256, replaces binary, restarts service
- Force-trigger: `POST /api/agents/:id/update`

---

## Active State

**Fleet (as of 2026-05-24 12:33 MST):**
- ~55 enrolled agents total; ~39 online
- 37 of 39 online agents on 0.6.38
- Laggards on 0.6.37: BB-SERVER (BirthBiologic, `6c02baa7-...`) and RECEPTIONIST-PC (Cascades of Tucson, `9c91d324-...`) — flaky WebSockets, miss dispatch windows. Force-update via API when their WS is up.

**Known enrolled clients/sites:**
- Cascades of Tucson — site CascadesTucson (RECEPTIONIST-PC, CS-SERVER)
- BirthBiologic — site BRIGHT-PEAK-5980
- Paul Key — site IRON-WOLF-5819
- ACG internal — AD2, DESKTOP-0O8A1RL, GURU-KALI, and one agent labeled "Saturn" [Saturn is DECOMMISSIONED as of Apr 2026; IP 172.16.3.21 reused by Uranus — this agent entry may be stale or may actually be Uranus]

**API auth:**
- `POST /api/auth/login` → JWT (~24h)
- Creds: vault `infrastructure/gururmm-server.sops.yaml` → `credentials.gururmm-api.admin-email` / `admin-password`
- Key endpoints: `GET /api/agents`, `POST /api/agents/:id/command`, `GET /api/commands/:id`, `POST /api/agents/:id/update`
- Command fields: `command_type` (powershell/shell/exec), `command` (script text, JSON-encoded). Windows agent runs as LocalSystem.
- Response: `stdout`, `stderr`, `exit_code`, `status` (running/completed/failed/timeout/interrupted)

**Dashboard — complete and working:**
Agents management, Clients/Sites CRUD, Commands execution + terminal, Logs + AI analysis, Alerts, Metrics (CPU/RAM/disk/network, process drill-down modal), Auto-update triggering, Network state, Entra ID SSO, Policies Dashboard (all tabs), Registry editor, MSP360 backup status card.

**Dashboard — incomplete (see UI_GAPS.md):**
- Temperature monitoring (BUG-001) — UI ready, agent-side collection never wired
- Enrollment management UI (revoke keys, audit log, duplicate hostname warnings)
- Watchdog alerts UI — blocked on 2 missing server routes
- MSPBackups management UI — backend complete, no frontend
- Organizations management UI — multi-tenancy backend done, no frontend
- Tunnel session management (interactive terminal — backend skeleton, not production-ready)

**Open Gitea issues:**
- #15 — Pipeline tray build (publish tray binary to downloads)
- #16 — Windows IPC peer authz
- #17 — logind console user resolution
- #18 — macOS tray
- #19 — subscriber broadcast

**Security backlog (HIGH):**
- `credentials/:id/reveal` — horizontal privilege escalation (no ownership scope check)
- `internal_err()` — ~130 call sites returning raw DB errors to callers

## Key Architecture Decisions (LOCKED)

These decisions are locked. Do not reverse without explicit user approval.

1. **Per-agent enrollment keys** — MSI contains server URL + site_id only. Agent calls `POST /api/enroll` on first run; server issues unique per-agent key stored hashed. Enables revocation, clone detection, audit trail.
2. **Site-specific MSI generation** — Universal base MSI from CI; dashboard endpoint generates site-specific MSI with site_id baked in via WiX property → `HKLM\SOFTWARE\GuruRMM\SiteId`.
3. **No TOML/config for endpoints** — Server URL compiled into binary. No runtime config files for server URL or site_id.
4. **Policy inheritance chain** — global → site → client → agent. Server computes merged effective policy and pushes via `ConfigUpdate` WebSocket message.
5. **Platform parity rule** — Any agent feature ships on Windows, Linux, and macOS in the same change. Stub + TODO required if a real implementation is not yet feasible.
6. **Watchdog as separate process** — Main agent cannot reliably restart itself after a crash.
7. **Build pipeline is the only path to production** — Enforces signing, checksum generation, consistent artifact layout.
8. **Multi-tenancy identity model (ADR-001)** — Dev team with partner impersonation. Three levels: Dev → Partner → Client. Computer Guru is partner #1.
9. **Holistic feature development (DESIGN.md)** — Every feature requires backend + API + dashboard UI + documentation. Backend-only features are rejected.
10. **AI-optional operation** — GuruRMM must be fully functional without AI. AI features are enhancements, not requirements.

## Compilation Notes

- macOS build status: Phase 1 was deployed manually from Mikes-MacBook-Air (2026-05-12). `build-mac.sh` is a stub as of 2026-05-24 — unclear if automated pipeline includes macOS yet. [unverified]
- Tunnel subsystem: agent-side substantially complete; server-side is dead-code skeleton. Current live status unconfirmed. [unverified]
- Pre-commit hook on 172.16.3.30 lacks execute bit (noted 2026-05-23) — likely still unfixed. [unverified]
- Auto-update reliability fix for BB-SERVER and RECEPTIONIST-PC was incomplete at 2026-05-24 save. [unverified]
