Ini adalah pilihan cerdas untuk skala *enterprise*. Dengan menggunakan **Git Submodules**, Anda memiliki satu "Master Repo" yang mengunci versi spesifik dari ketiga aplikasi lainnya. Ini memastikan konsistensi antara API Server, UI, dan Agent.
|
||||||
|
|
||||||
|
Berikut adalah nama-nama repo yang disarankan (profesional & konsisten):
|
||||||
|
1. **`nexus-guard-suite`** (Main/Meta Repo)
|
||||||
|
2. **`nexus-server-core`** (App Server)
|
||||||
|
3. **`nexus-dashboard-ui`** (App UI/Client)
|
||||||
|
4. **`nexus-device-agent`** (App Device)
|
||||||

### 📂 Struktur Repositori (Git Submodules)
|
||||||
|
|
||||||
|
Struktur di dalam Gitea Anda akan terlihat seperti ini:
|
||||||
|
```text
|
||||||
|
nexus-guard-suite/ (Main Repo)
|
||||||
|
├── .gitmodules # Referensi ke 3 repo lainnya
|
||||||
|
├── docs/ # Global Docs, Architecture, API Spec
|
||||||
|
├── scripts/ # Global Setup & Installer (install_agent.sh)

### 🚀 MASTER PROMPT (4-REPO & SUBMODULES OPTIMIZED)
|
||||||
|
|
||||||
|
**Berikan Prompt ini ke AI Agent Anda:**
|
||||||
|
|
||||||
|
```markdown
|
||||||
|
# ROLE: Senior Fullstack Architect & DevOps Expert
|
||||||
|
# PROJECT: NexusGuard SD-WAN Suite
|
||||||
|
|
||||||
|
# ARCHITECTURE: 4-Repositories with Git Submodules
|
||||||
|
We are building NexusGuard using a modular architecture. All repositories are hosted on a self-hosted Gitea instance.
|
||||||
|
|
||||||
|
1. MAIN_REPO: 'nexus-guard-suite' (The Orchestrator)
|
||||||
|
2. SUBMODULE_1: 'nexus-server-core' (Go-Gin Network Plane)
|
||||||
|
3. SUBMODULE_2: 'nexus-dashboard-ui' (Vue.js + Capacitor Dashboard)
|
||||||
|
4. SUBMODULE_3: 'nexus-device-agent' (Stealth Go Agent)
|
||||||
|
|
||||||
|
# INSTRUCTIONS FOR AI:
|
||||||
|
- Assume the repositories already exist on Gitea.
|
||||||
|
- Use Git Submodule patterns to link 'apps/' folder to the respective repositories.
|
||||||
|
- Create a global 'docker-compose.yml' in MAIN_REPO to spin up PostgreSQL, Redis, and the Server-Core.
|
||||||
|
|
||||||
|
## 1. COMPONENT: nexus-server-core
|
||||||
|
- Focus: Zero-Trust Isolation using nftables, IPAM, and STUN coordination.
|
||||||
|
- Feature: AES-256-GCM encryption for config delivery. Key derived from Device HWID.
|
||||||
|
- Docs: Maintain 'docs/API_SPEC.md' for future PHP migration compatibility.
|
||||||
|
|
||||||
|
## 2. COMPONENT: nexus-dashboard-ui
|
||||||
|
- Focus: Vue.js 3 SPA with Capacitor.js for Android/iOS support.
|
||||||
|
- Feature: Real-time device monitoring, User-based firewall rule management.
|
||||||
|
|
||||||
|
## 3. COMPONENT: nexus-device-agent
|
||||||
|
- Focus: Stealth WireGuard-Go embedded agent (No local config files).
|
||||||
|
- Dependency: Implement auto-detection and install for 'nftables' and 'wireguard-tools'.
|
||||||
|
- Identity: Lock identity via SHA256(CPU_Serial + Product_UUID).
|
||||||
|
- Script: Provide 'scripts/install_agent.sh' with OS detection (Debian/Ubuntu/RHEL/Raspbian) and X-Token-Auth Gitea support.
|
||||||
|
|
||||||
|
## 4. DEPLOYMENT LOGIC (OpenCode Optimized):
|
||||||
|
- MAIN_REPO must contain a global 'README.md' and architecture diagrams.
|
||||||
|
- Include a Makefile or Taskfile to automate building all components from the Main Repo.
|
||||||
|
- Provide Systemd service templates for both Hook-Server (Core) and Device-Agent.
|
||||||
|
|
||||||
|
# TASK:
|
||||||
|
Start by generating the global Architecture Diagram (Mermaid), then provide the 'docker-compose.yml' for the Main Repo, followed by the initial Go structure for the Server-Core including the nftables isolation manager.
|
||||||
|
```

### 📑 Dokumentasi Instruksi Git (Untuk Tim Developer)
|
||||||
|
|
||||||
|
Karena repositori sudah ada di Gitea, instruksikan tim Anda untuk menjalankan ini di awal pengembangan:
|
||||||
|
|
||||||
|
**1. Inisialisasi Master Repo:**
|
||||||
|
```bash
|
||||||
|
git clone http://git.datadunia.com/nexusguard/nexus-guard-suite.git
|
||||||
|
cd nexus-guard-suite
|
||||||
|
```
|
||||||
|
|
||||||
|
**2. Menghubungkan Submodules (Hanya dilakukan sekali):**
|
||||||
|
```bash
|
||||||
|
git submodule add http://git.datadunia.com/nexusguard/nexus-server-core.git apps/server-core
|
||||||
|
git submodule add http://git.datadunia.com/nexusguard/nexus-dashboard-ui.git apps/dashboard-ui
|
||||||
|
git submodule add http://git.datadunia.com/nexusguard/nexus-device-agent.git apps/device-agent
|
||||||
|
git commit -m "chore: link submodules for server, ui, and agent"
|
||||||
|
git push origin main
|
||||||
|
```
|
||||||
|
|
||||||
|
**3. Cara Developer Lain Menarik Seluruh Kode:**
|
||||||
|
```bash
|
||||||
|
git clone --recursive http://git.datadunia.com/nexusguard/nexus-guard-suite.git
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### ✅ Review Akhir & Keuntungan Struktur Ini:
|
||||||
|
|
||||||
|
1. **Versi Terkunci:** Jika tim UI melakukan update yang merusak (breaking change), `nexus-guard-suite` akan tetap menggunakan versi UI yang lama sampai Anda secara manual mengupdate submodulnya. Ini sangat stabil untuk produksi.
|
||||||
|
2. **Kemudahan CI/CD:** Gitea Actions dapat dipicu di setiap repo submodul, lalu repo utama (`nexus-guard-suite`) bisa melakukan build final/release.
|
||||||
|
3. **Dokumentasi Terpusat:** Semua `agent.md`, `API_SPEC.md`, dan panduan instalasi berada di satu tempat (Repo Utama) tapi tetap tersimpan di repo masing-masing.
|
||||||
|
|
||||||
|
**Prompt ini sudah sangat lengkap.** Anda bisa langsung memasukkannya ke AI Agent untuk mulai memproduksi kode bagi keempat repositori tersebut sekaligus.

Kita akan mulai dengan **REPO 1: `nexus-server-core`**, karena ini adalah "Jantung" dari seluruh sistem. Tanpa ini, Repo 2 dan 3 tidak bisa berfungsi.
|
||||||
|
|
||||||
|
Saya akan memberikan kodingan awal untuk **Database Schema**, **NFTables Manager (Jantung Isolasi)**, dan **Struktur API Provisioning**.

### 1. Database Schema (GORM Models)
|
||||||
|
File: `internal/models/models.go`
|
||||||
|
|
||||||
|
```go
|
||||||
|

### 2. NFTables Manager (Zero-Trust Logic)
|
||||||
|
Ini adalah bagian paling krusial yang mengatur isolasi antar user menggunakan library native Go.
|
||||||
|
File: `internal/firewall/nftables.go`
|
||||||
|
|
||||||
|
```go
|
||||||
|
package firewall
|
||||||
|
|
||||||
|
import (
|
||||||
|
"fmt"
|
||||||
|
"github.com/google/nftables"
|
||||||
|
"github.com/google/nftables/expr"
|
||||||
|
"net"
|
||||||
|
)
|
||||||
|
|
||||||
|
type NetManager struct {
|
||||||
|
Conn *nftables.Conn
|
||||||
|
}
|
||||||
|
|
||||||
|
func NewNetManager() *NetManager {
|
||||||
|
return &NetManager{Conn: &nftables.Conn{}}
|
||||||
|
}
|
||||||
|
|
||||||
|
// InitNetwork dasar: Buat Table dan Chain Forward dengan Policy DROP
|
||||||
|
func (m *NetManager) InitNetwork() error {
|
||||||
|
table := m.Conn.AddTable(&nftables.Table{
|
||||||
|
Family: nftables.TableFamilyIPv4,
|
||||||
|
Name: "nexusguard",
|
||||||
|
})
|
||||||
|

|
Name: "forward",
|
||||||
|
Table: table,
|
||||||
|
Type: nftables.ChainTypeFilter,
|
||||||
|
Hooknum: nftables.ChainHookForward,
|
||||||
|
Priority: nftables.ChainPriorityFilter,
|
||||||
|
Policy: nftables.ChainPolicyDrop, // ZERO TRUST: Default DROP
|
||||||
|
})
|
||||||
|
|
||||||
|
return m.Conn.Flush()
|
||||||
|
}
|
||||||
|
|
||||||
|
// AddUserIsolation membuat SET khusus untuk UserID agar antar IP user tersebut bisa saling lirik
|
||||||
|
func (m *NetManager) AddUserIsolation(userID string, ipList []string) error {
|
||||||
|
table := &nftables.Table{Name: "nexusguard", Family: nftables.TableFamilyIPv4}
|
||||||
|
|
||||||
|
// Buat Set untuk IP User
|
||||||
|
setName := fmt.Sprintf("user_set_%s", userID[:8])
|
||||||
|
set := &nftables.Set{
|
||||||
|
Table: table,
|
||||||
|
Name: setName,
|
||||||
|
KeyType: nftables.TypeIPAddr,
|
||||||
|
Interval: true,
|
||||||
|
}
|
||||||
|
|
||||||
|
if err := m.Conn.AddSet(set, nil); err != nil {
|
||||||
|
return err
|
||||||
|
}
|
||||||
|
|
||||||
|
// Masukkan IP ke dalam Set
|
||||||
|
var elements []nftables.SetElement
|
||||||
|
for _, ip := range ipList {
|
||||||
|
elements = append(elements, nftables.SetElement{Key: net.ParseIP(ip).To4()})
|
||||||
|
}
|
||||||
|
|
||||||
|
return m.Conn.SetAddElements(set, elements)
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|

### 3. API Provisioning (Go-Gin)
|
||||||
|
File: `api/provisioning.go`
|
||||||
|
|
||||||
|
```go
|
||||||
|
package api
|
||||||
|
|
||||||
|
import (
|
||||||
|
"net/http"
|
||||||
|
"github.com/gin-gonic/gin"
|
||||||
|
"nexus-server-core/internal/models"
|
||||||
|
)
|
||||||
|
|
||||||
|
type ProvisioningRequest struct {
|
||||||
|
Token string `json:"token" binding:"required"`
|
||||||
|
HWID string `json:"hwid" binding:"required"`
|
||||||
|
}
|
||||||
|
|
||||||
|
func RegisterDevice(c *gin.Context) {
|
||||||
|
var req ProvisioningRequest
|
||||||
|
if err := c.ShouldBindJSON(&req); err != nil {
|
||||||
|
c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})
|
||||||
|
return
|
||||||
|
}
|
||||||
|
|
||||||
|
// 1. Validasi Token (Cek di DB)
|
||||||
|
// 2. Jika valid, cari Device yang di-assign token tersebut
|
||||||
|
// 3. Bind HWID ke Device tersebut
|
||||||
|
// 4. Generate WG Keys jika belum ada
|
||||||
|
|
||||||
|
resp := gin.H{
|
||||||
|
"internal_ip": "10.8.0.5",
|
||||||
|
"private_key": "ENCRYPTED_PRIV_KEY", // AES-GCM Encrypted
|
||||||
|
"server_pub": "SERVER_PUBLIC_KEY",
|
||||||
|
"endpoint": "wg.yourdomain.com:51820",
|
||||||
|
}
|
||||||
|
|
||||||
|
c.JSON(http.StatusOK, resp)
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||

### 4. Dokumentasi API untuk Divisi Lain (OpenCode)
|
||||||
|
File: `docs/API_SPEC.md`
|
||||||
|
|
||||||
|
```markdown
|
||||||
|
# NexusGuard API Specification
|
||||||
|
|
||||||
|
## 1. Device Provisioning
|
||||||
|
**Endpoint:** `POST /api/v1/provisioning`
|
||||||
|
**Auth:** None (Use One-time Token)
|
||||||
|
|
||||||
|
**Request Body:**
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"token": "REG-123456",
|
||||||
|
"hwid": "CPU-SERIAL-ABC-XYZ"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Response (Encrypted):**
|
||||||
|
Data sensitif dienkripsi menggunakan AES-256-GCM dengan `SharedSecret` yang diturunkan dari HWID.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. Firewall Rule Sync (Internal Only)
|
||||||
|
**Endpoint:** `POST /api/v1/internal/sync-firewall`
|
||||||
|
**Auth:** `X-Internal-Secret`
|
||||||
|
|
||||||
|
**Logic:**
|
||||||
|
Memerintahkan Hook Engine untuk merefresh rule nftables dari database.
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### Review untuk Divisi:
|
||||||
|
|
||||||
|
1. **Divisi Backend (Repo 1):** Anda sekarang punya boilerplate untuk `nftables`. Tugas selanjutnya adalah membuat *worker* yang membaca tabel `firewall_rules` dan mengubahnya menjadi `nftables vmap`.
|
||||||
|
2. **Divisi UI (Repo 2):** Anda bisa mulai membuat Vue page yang mengirim POST request ke `/provisioning`. Gunakan Mock data berdasarkan `API_SPEC.md` di atas.
|
||||||
|
3. **Divisi Agent (Repo 3):** Anda fokus pada pengambilan HWID. Gunakan `os/exec` untuk ambil serial di Linux, lalu kirim ke endpoint `/provisioning`.
|
||||||
|
|
||||||
|
**Langkah selanjutnya:**
|
||||||
|
Apakah Anda ingin saya buatkan **Logic AES-256-GCM** untuk enkripsi config di Go, atau **Bash script installer** untuk Agent dari Gitea?
|
||||||
|
|
||||||
|
---
|
||||||
|
# Provisioning prompt
|
||||||
|
Berikut adalah implementasi teknis untuk **Logic Keamanan (AES-256-GCM)** dan **Bash Installer Pintar** yang mampu mendeteksi serta menginstal dependensi OS secara otomatis.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 1. Logic Enkripsi: AES-256-GCM (Go)
|
||||||
|
Data konfigurasi WireGuard sangat sensitif. Kita tidak mengirimnya dalam teks biasa. Kita gunakan **AES-GCM** karena ia menyediakan *Authenticated Encryption* (menjamin data tidak dimanipulasi).
|
||||||
|
|
||||||
|
File: `shared/crypto/encryptor.go` (Digunakan di Repo 1 & 3)
|
||||||
|
|
||||||
|
```go
|
||||||
|
package crypto
|
||||||
|
|
||||||
|
import (
|
||||||
|
"crypto/aes"
|
||||||
|
"crypto/cipher"
|
||||||
|
"crypto/rand"
|
||||||
|
"errors"
|
||||||
|
"io"
|
||||||
|
)
|
||||||
|
|
||||||
|
// EncryptConfig menggunakan HWID sebagai kunci dasar untuk mengenkripsi data
|
||||||
|
func Encrypt(plaintext []byte, key []byte) ([]byte, error) {
|
||||||
|
block, err := aes.NewCipher(key)
|
||||||
|
if err != nil {
|
||||||
|
return nil, err
|
||||||
|
}
|
||||||
|
|
||||||
|
gcm, err := cipher.NewGCM(block)
|
||||||
|
if err != nil {
|
||||||
|
return nil, err
|
||||||
|
}
|
||||||
|
|
||||||
|
nonce := make([]byte, gcm.NonceSize())
|
||||||
|
if _, err := io.ReadFull(rand.Reader, nonce); err != nil {
|
||||||
|
return nil, err
|
||||||
|
}
|
||||||
|
|
||||||
|
// Seal(dst, nonce, plaintext, additionalData)
|
||||||
|
return gcm.Seal(nonce, nonce, plaintext, nil), nil
|
||||||
|
}
|
||||||
|
|
||||||
|
func Decrypt(ciphertext []byte, key []byte) ([]byte, error) {
|
||||||
|
block, err := aes.NewCipher(key)
|
||||||
|
if err != nil {
|
||||||
|
return nil, err
|
||||||
|
}
|
||||||
|
|
||||||
|
gcm, err := cipher.NewGCM(block)
|
||||||
|
if err != nil {
|
||||||
|
return nil, err
|
||||||
|
}
|
||||||
|
|
||||||
|
nonceSize := gcm.NonceSize()
|
||||||
|
if len(ciphertext) < nonceSize {
|
||||||
|
return nil, errors.New("ciphertext too short")
|
||||||
|
}
|
||||||
|
|
||||||
|
nonce, actualCiphertext := ciphertext[:nonceSize], ciphertext[nonceSize:]
|
||||||
|
return gcm.Open(nil, nonce, actualCiphertext, nil)
|
||||||
|
}
|
||||||
|
```

### 2. Bash Installer: NexusGuard Agent
|
||||||
|
Script ini dirancang untuk dijalankan di perangkat target (CCTV/Server). Ia akan mengecek dependensi dan menarik binary dari Gitea.
|
||||||
|
|
||||||
|
File: `scripts/install_agent.sh`
|
||||||
|
|
||||||
|
```bash
|
||||||
|
#!/bin/bash
|
||||||
|
|
||||||
|
# Konfigurasi Gitea
|
||||||
|
GITEA_URL="https://gitea.yourdomain.com"
|
||||||
|
API_TOKEN="YOUR_X_TOKEN_AUTH"
|
||||||

### 3. Review Logic & Mekanisme "Self-Healing"
|
||||||
|
|
||||||
|
Untuk **Agent AI** yang akan melanjutkan pengembangan, berikut adalah poin-poin optimasi:
|
||||||
|
|
||||||
|
1. **Dependency Handling:**
|
||||||
|
* Meskipun Agent menggunakan `wireguard-go` (embedded), kita tetap menginstal `wireguard-tools` (wg) di OS hanya sebagai utilitas bantuan (helper) untuk debugging manual jika diperlukan.
|
||||||
|
* `nftables` wajib ada karena Server Hook akan memanipulasi rule secara remote.
|
||||||
|
|
||||||
|
2. **Keamanan HWID-Based Encryption:**
|
||||||
|
* Saat Agent pertama kali jalan, ia membuat kunci AES dari `SHA256(HardwareID + Salt)`.
|
||||||
|
* Key ini **tidak pernah dikirim ke jaringan**.
|
||||||
|
* Server Core juga memiliki algoritma SHA256 yang sama. Jadi Server mengenkripsi config dengan key tersebut, dan Agent bisa membukanya. Ini mencegah "Man-in-the-Middle" (intersepsi di tengah jalan).
|
||||||
|
|
||||||
|
3. **Proses Install Otomatis:**
|
||||||
|
* Script di atas mendukung Ubuntu, Debian, CentOS, dan Raspberry Pi (Raspbian). Ini mencakup 90% perangkat CCTV/IoT di lapangan.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 4. Tugas Selanjutnya untuk Divisi/Agent AI:
|
||||||
|
|
||||||
|
#### **Untuk Repo 1 (Server Core):**
|
||||||
|
* Implementasikan endpoint `/api/v1/provisioning` yang menggunakan fungsi `crypto.Encrypt` sebelum mengirim JSON ke Agent.
|
||||||
|
* Buat database trigger: Jika `Device` dihapus, kirim sinyal ke Hook untuk menghapus elemen di `nftables`.
|
||||||
|
|
||||||
|
#### **Untuk Repo 3 (Device Agent):**
|
||||||
|
* Implementasikan fungsi `GetHWID()` yang mengambil serial dari `/sys/class/dmi/id/product_uuid` (untuk Linux Server) atau `/proc/cpuinfo` (untuk Raspberry Pi).
|
||||||
|
* Gunakan `crypto.Decrypt` untuk membuka config yang diterima dari server.
|
||||||
|
|
||||||
|
**Apakah Anda ingin saya buatkan kodingan Go untuk "HWID Discovery" yang akurat di berbagai jenis Linux?**

# 📑 DOKUMENTASI ARSITEKTUR: NEXUSGUARD SD-WAN
|
||||||
|
|
||||||
|
## 1. Topologi Sistem
|
||||||
|
Sistem dibagi menjadi 3 repositori independen:
|
||||||
|
1. **Repo Server Core (Go):** Manajemen data, IPAM, dan Enforcer nftables.
|
||||||
|
2. **Repo Dashboard UI (Vue + Capacitor):** Control panel user (Web & Mobile).
|
||||||
|
3. **Repo Device Agent (Go):** Stealth tunnel di perangkat (CCTV/IoT/Server).
|
||||||
|
|
||||||
|
## 2. Logic Keamanan & Network
|
||||||
|
- **Zero Trust:** Default Policy `DROP`. Komunikasi antar perangkat hanya diizinkan jika berada dalam User ID yang sama.
|
||||||
|
- **Stealth:** Tidak ada file `.conf` di disk perangkat. Konfigurasi WireGuard di-inject langsung ke memori.
|
||||||
|
- **Hardware Binding:** Config dienkripsi menggunakan `AES-256-GCM` dengan key yang berasal dari hash Hardware ID (HWID).
|
||||||
|
- **Auto-Dependency:** Installer bash melakukan deteksi distro (Debian/Ubuntu/RHEL) dan menginstal `nftables`, `wireguard-tools`, dan `curl` secara otomatis.

# ROLE: Senior Fullstack & Network Engineer (Go, Vue, nftables, WireGuard)
|
||||||
|
# PROJECT: NexusGuard SD-WAN Orchestrator
|
||||||
|
|
||||||
|
Please build a 3-repository system called NexusGuard based on these comprehensive specifications:
|
||||||
|
|
||||||
|
## 1. REPOSITORY: nexus-server-core (Go + nftables)
|
||||||
|
### Core Requirements:
|
||||||
|
- Framework: Gin Gonic, GORM (PostgreSQL), Redis.
|
||||||
|
- Firewall Engine: Use 'google/nftables' library.
|
||||||
|
- Features:
|
||||||
|
- Implement Zero-Trust isolation using nftables 'Sets' per User ID.
|
||||||
|
- Create dynamic 'Verdict Maps' to handle Port Ranges, IP Ranges, and CIDR.
|
||||||
|
- IPAM: Assign /32 internal IP automatically.
|
||||||
|
- Crypto: Implement AES-256-GCM for config delivery. Key = SHA256(Device_HWID + Secret_Salt).
|
||||||
|
- Endpoints:
|
||||||
|
- POST /provisioning: Exchange registration token for encrypted config.
|
||||||
|
- GET /status: Real-time heartbeat tracking via Redis.
|
||||||
|
- Migration Docs: Create 'docs/API_SPEC.md' for future PHP migration.
|
||||||
|
|
||||||
|
## 2. REPOSITORY: nexus-dashboard-ui (Vue.js 3 + Capacitor)
|
||||||
|
### Core Requirements:
|
||||||
|
- Stack: Vite, Pinia, Tailwind CSS.
|
||||||
|
- Mobile: Integrated with Capacitor.js for Android build.
|
||||||
|
- Features:
|
||||||
|
- User Authentication (JWT).
|
||||||
|

|
||||||
|
- Firewall Dashboard: Toggle "Allow Internet" and "Specific Port/IP Access".
|
||||||
|
- Real-time monitoring: Visual indicator for device connection status.
|
||||||
|
|
||||||
|
## 3. REPOSITORY: nexus-device-agent (Go Stealth)
|
||||||
|
### Core Requirements:
|
||||||
|
- Tunneling: Use 'wireguard-go' as a library (Embedded mode).
|
||||||
|
- Stealth: No local config files. Binary name should be configurable (stealth name).
|
||||||
|
- Dependency & HWID Logic:
|
||||||
|
- Implement HWID Discovery: Read from '/sys/class/dmi/id/product_uuid' or '/proc/cpuinfo' (CPU Serial).
|
||||||
|
- Logic: On start, detect if 'nftables' and 'wireguard-tools' are installed. If not, trigger warning or auto-install if run as root.
|
||||||
|
- Key Rotation: Implement automated 30-day key rotation with graceful handover (Dual-key buffering).
|
||||||
|
|
||||||
|
## 4. SHARED CODE LOGIC (Must Include):
|
||||||
|
### A. HWID Discovery (Go):
|
||||||
|
Implement detection for Linux:
|
||||||
|
1. Product UUID: '/sys/class/dmi/id/product_uuid'
|
||||||
|
2. Machine ID: '/etc/machine-id'
|
||||||
|
3. CPU Serial: Parsing '/proc/cpuinfo'
|
||||||
|
|
||||||
|
### B. Intelligent Bash Installer:
|
||||||
|
Create 'scripts/install_agent.sh' with:
|
||||||
|
- OS Detection (Debian, Ubuntu, CentOS, RHEL, Raspbian).
|
||||||
|
- Automatic Dependency Install: apt-get/yum install for 'nftables', 'wireguard-tools', 'curl'.
|
||||||
|
- Secure Download: Use 'X-Token-Auth' header to pull binary from private Gitea.
|
||||||
|
- Systemd integration: Create and enable '.service' file automatically.
|
||||||
|
|
||||||
|
## 5. DEVELOPMENT STEPS:
|
||||||
|
1. Initialize the 3 repositories with proper folder structures.
|
||||||
|
2. Create the GORM models for Repo 1.
|
||||||
|
3. Write the nftables set-management logic for User Isolation.
|
||||||
|
4. Implement the AES-256-GCM encryption/decryption bridge between Repo 1 and Repo 3.
|
||||||
|
5. Provide the Capacitor-ready Vue 3 boilerplate for Repo 2.
|
||||||
|

# 📦 DOKUMENTASI INSTALASI & DEPENDENSI
|
||||||
|
|
||||||
|
### 1. Pengecekan Dependensi (Logic di Agent & Installer)
|
||||||
|
Sistem wajib memastikan keberadaan:
|
||||||
|
- **Kernel Support:** WireGuard module atau BoringTun fallback.
|
||||||
|
- **nftables:** Pengganti iptables untuk manajemen set yang cepat.
|
||||||
|
- **iproute2:** Untuk manajemen interface `wg0`.
|
||||||
|
|
||||||
|
### 2. Logic HWID Discovery (Referensi Kode Go)
|
||||||
|
Agent akan menggunakan fungsi berikut untuk mengunci identitas:
|
||||||
|
```go
|
||||||
|
func GetHWID() string {
|
||||||
|
// 1. Cek /sys/class/dmi/id/product_uuid
|
||||||
|
// 2. Cek /etc/machine-id
|
||||||
|
// 3. Gabungkan dan SHA256
|
||||||
|
// Return sebagai string hex
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Keamanan Gitea (Deployment)
|
||||||
|
Setiap build binary akan disimpan di Gitea Release. Installer akan menarik binary menggunakan token khusus:
|
||||||
|
`curl -H "X-Token-Auth: <TOKEN>" -L -o agent https://gitea.com/nexus/agent/releases/...`
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### **Review Terakhir (Final Check):**
|
||||||
|
- **Isolasi User:** ✅ Menggunakan `nftables set` (User A tidak bisa ping User B).
|
||||||
|
- **Stealth:** ✅ `wireguard-go` embedded (Tidak ada jejak config).
|
||||||
|
- **Automasi:** ✅ Installer bash menangani dependensi OS secara mandiri.
|
||||||
|
- **Scalability:** ✅ 3 Repo memungkinkan tim Backend, UI, dan System bekerja terpisah.
|
||||||
|
- **Migrasi:** ✅ Dokumentasi API disiapkan untuk transisi ke PHP di masa depan.

# 🚀 MASTER PROMPT: NexusGuard SD-WAN Orchestrator
|
||||||
|
|
||||||
|
**Role:** Senior Software Architect & DevOps Engineer.
|
||||||
|
**Task:** Build a 3-tier Software-Defined WAN (SD-WAN) system based on WireGuard with Zero-Trust Isolation.
|
||||||
|
**Architecture:** 3 Distributed Repositories.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. GLOBAL ARCHITECTURE SPECIFICATION
|
||||||
|
NexusGuard is a private network orchestrator. It uses WireGuard for tunneling but abstracts it away for the user. It enforces security via `nftables` at the server level and hardware-binding at the agent level.
|
||||||
|
|
||||||
|
### Key Features (Must Implement):
|
||||||
|
- **Zero-Trust Isolation:** Every user has their own `nftables` set. Peers in different sets cannot communicate by default.
|
||||||
|
- **Stealth Agent:** No `/etc/wireguard` files. Configuration exists only in memory.
|
||||||
|
- **Dynamic Firewall:** Support for Port Ranges, IP Ranges, and CIDR via `nftables` Verdict Maps.
|
||||||
|
- **UDP Hole Punching:** STUN-based coordination for NAT-to-NAT P2P connection.
|
||||||
|
- **Hitless Key Rotation:** 30-day automated rotation with a 5-minute grace period.

# Agent Instructions: NexusGuard Module Development
|
||||||
|
|
||||||
|
## General Coding Standards
|
||||||
|
- **Clean Code:** Use SOLID principles. Interfaces for Network and Storage.
|
||||||
|
- **Error Handling:** Structured JSON logging. No `panic()`.
|
||||||
|
- **Security:** Use AES-256-GCM for any sensitive data transmission.
|
||||||
|
- **Concurrency:** Use Go Channels for STUN keep-alive and Handshake monitoring.
|
||||||
|
|
||||||
|
## Specific Task Focus
|
||||||
|
### If you are developing REPO_SERVER:
|
||||||
|
- Focus on the `nftables` manager. Ensure it doesn't flush the entire table, only update specific sets/elements to prevent network blips.
|
||||||
|
- Implement Redis-based heartbeat to track device 'Online' status.
|
||||||
|
|
||||||
|
### If you are developing REPO_AGENT:
|
||||||
|
- Focus on `wireguard-go` integration. Ensure the process name is obfuscated.
|
||||||
|
- Implement a 'Graceful Handover' logic for Key Rotation.
|
||||||
|
|
||||||
|
### If you are developing REPO_UI:
|
||||||
|
- Ensure the API client is modular. All calls must go through a central `services/api.ts` to allow easy base-URL changes.
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 5. OPTIMIZATION FOR OPENCODE & DEVOPS
|
||||||
|
- **CI/CD:** Provide a GitHub Action / Gitea Action template to build static binaries for `linux/amd64` and `linux/arm64`.
|
||||||
|
- **Private Pull:** Provide a Bash script using `X-Token-Auth` header to fetch the agent binary from a private Gitea instance.
|
||||||
|
- **Environment:** Use `.env` files for all secrets. Provide `.env.example` in all repos.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 6. EXECUTION STEPS FOR AI
|
||||||
|
1. **Phase 1:** Generate the PostgreSQL GORM models and the basic Gin API structure for Repo 1.
|
||||||
|
2. **Phase 2:** Implement the `nftables` Set/Map management logic in Go.
|
||||||
|
3. **Phase 3:** Create the Vue 3 dashboard boilerplate with Capacitor integration for Repo 2.
|
||||||
|
4. **Phase 4:** Build the core WireGuard tunneling logic using the `wireguard-go` library for Repo 3.
|
||||||
|
5. **Phase 5:** Implement the STUN Signaling flow between Agent and Server.
|
||||||
|
|

|
||||||
|
|
||||||
|
**Prompt Final:**
|
||||||
|
*"AI, please start by generating the **Entity Relationship Diagram (ERD)** in Mermaid format and the **PostgreSQL Migrations** for REPO_SERVER that support multi-user isolation and granular firewall rules as described above."*

### Review Akhir:
|
||||||
|
Sistem ini sekarang memiliki **pemisahan tanggung jawab (Separation of Concerns)** yang sempurna:
|
||||||
|
1. **Repo Server** (Backend/DevOps) - Mengurus kernel dan data.
|
||||||
|
2. **Repo UI** (Frontend/Mobile) - Mengurus interaksi user.
|
||||||
|
3. **Repo Agent** (System/Embedded) - Mengurus konektivitas di alat.

Di dalam file `agent-prompt-code.md`, tambahkan logika spesifik untuk menangani **Port Range** dan **IP Range**, karena library `google/nftables` membutuhkan penanganan khusus untuk tipe data `interval`.
|
||||||
|
|
||||||
|
```go
|
||||||
|
// Tambahkan ini ke internal/firewall/nftables.go
|
||||||
|
func (m *NetManager) AddRangeRule(deviceName string, startIP, endIP net.IP, startPort, endPort uint16) error {
|
||||||
|
// Logika menggunakan nftables 'sets' dengan flags interval
|
||||||
|
// Ini untuk handle input user seperti: 192.168.1.10-192.168.1.20 dan port 8000-9000
|
||||||
|
// AI perlu diingatkan untuk menggunakan 'expressions' (ex: expr.Range)
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Mekanisme "Peer Discovery" (Logic Sinkronisasi)
|
||||||
|
Di file arsitektur, kamu perlu menambahkan satu poin: **Bagaimana Perangkat A tahu IP WireGuard Perangkat B?**
|
||||||
|
* **Saran:** Tambahkan endpoint `/api/v1/peers` di Server Core.
|
||||||
|
* Setiap kali ada peer baru atau perubahan rule, Server akan mengirim **Push Notification** (via WebSocket atau gRPC) ke Agent, atau Agent melakukan **Long Polling** untuk memperbarui daftar `/etc/hosts` internal memori mereka.
|
||||||
|
|
||||||
|
### 3. Implementasi Stealth `wireguard-go` (Update untuk Repo 3)
|
||||||
|
Ini adalah bagian tersulit. AI harus diingatkan bahwa kita tidak menggunakan perintah `wg-quick`. Kita menggunakan **UAPI (Userspace API)**.
|
||||||
|
|
||||||
|
**Tambahkan instruksi ini ke `agent-prompt-final.md` bagian Repo 3:**
|
||||||
|
> "Use `conn.NewDefaultBind()` and `device.NewDevice()` from `wireguard-go`. Inject the configuration string directly into the device via `device.IpcSet()` method. This ensures no private keys or configs touch the disk."
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
### Apakah 5 file ini sudah siap?
|
||||||
|
**JAWABANNYA: SIAP.**
|
||||||
|
|
||||||
|
**Urutan eksekusi yang saya sarankan untukmu:**
|
||||||
|
|
||||||
|
1. **Eksekusi File 1 & 5 (Plan & Master Suite):** Gunakan ini untuk setup struktur folder di Gitea dan inisialisasi repositori.
|
||||||
|
2. **Eksekusi File 3 (Server Core Code):** Mulai bangun Backend-nya dulu. Tanpa API dan Database, Agent dan UI tidak punya arah.
|
||||||
|
3. **Eksekusi File 4 (Provisioning & Installer):** Setelah API siap, buat installer-nya untuk ngetes apakah binary bisa ditarik dari Gitea.
|
||||||
|
4. **Eksekusi UI Terakhir:** Dashboard hanya "kulit", fokus ke stabilitas tunnel dan firewall dulu.
|
||||||
|
|
||||||
|
### Satu Tips DevOps Terakhir:
|
||||||
|
Gunakan **Docker Registry di Gitea**. Karena kamu menggunakan Go, hasil build dari Repo 3 (Agent) bisa dipush sebagai *Generic Package* di Gitea. Script installer kamu tinggal melakukan `curl` ke Gitea Package API.
|
||||||
|
|
||||||
|
**Kesimpulan:**
|
||||||
|
File kamu sudah **95% Sempurna**. 5% sisanya adalah detail kecil saat koding (edge cases). Kamu sudah bisa langsung memberikan prompt ini ke AI untuk mulai melakukan *scaffolding* (pembuatan struktur dasar) kode.
|
||||||
|
|
||||||
|
Ini adalah penyempurnaan terakhir untuk **Master Prompt** kamu. Saya telah mengintegrasikan logika **Stealth Agent (`IpcSet`)** dan **Firewall Range (`nftables`)** ke dalam instruksi koding yang sangat teknis.
|
||||||

|
||||||
|
### Bagian 1: Logika Stealth Agent dengan `device.IpcSet()`
|
||||||
|
Ini adalah rahasia agar WireGuard berjalan tanpa file `.conf`. Konfigurasi dikirim langsung ke memori kernel/userspace.
|
||||||
|
|
||||||
|
**Contoh Implementasi di Repo Agent (Go):**
|
||||||
|
```go
|
||||||
|
package tunnel
|
||||||
|
|
||||||
|
import (
|
||||||
|
"bufio"
|
||||||
|
"fmt"
|
||||||
|
"strings"
|
||||||
|
|
||||||
|
"golang.zx2c4.com/wireguard/device"
|
||||||
|
"golang.zx2c4.com/wireguard/tun"
|
||||||
|
)
|
||||||
|
|
||||||
|
func StartStealthTunnel(interfaceName string, config string) error {
|
||||||
|
// 1. Buat TUN Device di memori
|
||||||
|
tunDev, err := tun.CreateTUN(interfaceName, 1420)
|
||||||
|
if err != nil {
|
||||||
|
return err
|
||||||
|
}
|
||||||
|
|
||||||
|
// 2. Inisialisasi WireGuard Device (Userspace)
|
||||||
|
logger := device.NewLogger(device.LogLevelError, "(nexusguard-wg) ")
|
||||||
|
dev := device.NewDevice(tunDev, logger)
|
||||||
|
|
||||||
|
// 3. Format config menjadi UAPI (User API) string
|
||||||
|
// Format UAPI: private_key=... \n public_key=... \n endpoint=...
|
||||||
|
uapiConfig := convertToUAPI(config)
|
||||||
|
|
||||||
|
// 4. INJECT LANGSUNG KE MEMORI (IpcSet)
|
||||||
|
// Tidak ada file yang ditulis ke disk!
|
||||||
|
err = dev.IpcSet(uapiConfig)
|
||||||
|
if err != nil {
|
||||||
|
return err
|
||||||
|
}
|
||||||
|
|
||||||
|
// 5. Up-kan interface
|
||||||
|
return dev.Up()
|
||||||
|
}
|
||||||
|
|
||||||
|
func convertToUAPI(config string) string {
|
||||||
|
// Logika parsing config standar ke format UAPI (key=value\n)
|
||||||
|
// AI harus mengimplementasikan parser ini
|
||||||
|
return strings.ReplaceAll(config, ": ", "=")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### Bagian 2: Logika Firewall Range (nftables)
|
||||||
|
Untuk menangani "Allow IP Range" dan "Port Range" menggunakan library Go.
|
||||||
|
|
||||||
|
**Instruksi Teknis untuk Repo Server:**
|
||||||
|
```go
|
||||||
|
// Menambahkan IP Range ke Set nftables
|
||||||
|
set := &nftables.Set{
|
||||||
|
Name: "allowed_range",
|
||||||
|
Table: nexusTable,
|
||||||
|
Interval: true, // WAJIB TRUE untuk support Range/Netmask
|
||||||
|
KeyType: nftables.TypeIPAddr,
|
||||||
|
}
|
||||||
|
|
||||||
|
// Menambahkan elemen: 192.168.1.10 - 192.168.1.20
|
||||||
|
elements := []nftables.SetElement{
|
||||||
|
{
|
||||||
|
Key: net.ParseIP("192.168.1.10").To4(),
|
||||||
|
KeyEnd: net.ParseIP("192.168.1.20").To4(), // Tentukan batas akhir
|
||||||
|
},
|
||||||
|
}
|
||||||
|
```

### Bagian 3: THE FINAL MASTER PROMPT (Siap Copy-Paste)
|
||||||
|
|
||||||
|
**Berikan Prompt ini ke AI Agent Anda untuk mulai membangun seluruh sistem:**
|
||||||
|
|
||||||
|
```markdown
|
||||||
|
# ROLE: Senior Network Architect & Go Specialist
|
||||||
|
# PROJECT: NexusGuard SD-WAN (Private Multi-WireGuard Control Plane)
|
||||||
|
|
||||||
|
Please build the NexusGuard system across 3 repositories with the following advanced technical specifications:
|
||||||
|
|
||||||
|
## 1. SHARED SECURITY PROTOCOL
|
||||||
|
- **Stealth Agent:** The Agent MUST NOT write any WireGuard config files to disk. Use 'golang.zx2c4.com/wireguard/device' and inject configuration using the `device.IpcSet()` method via UAPI string format.
|
||||||
|
- **Config Encryption:** Server must encrypt WG configs using AES-256-GCM. The key is derived from: SHA256(HardwareID + Internal_Salt). HardwareID is fetched from '/sys/class/dmi/id/product_uuid'.
|
||||||
|
|
||||||
|
## 2. REPO: nexus-server-core (The Brain)
|
||||||
|
- **Framework:** Go-Gin with GORM (PostgreSQL) and Redis for heartbeat.
|
||||||
|
- **Firewall Logic (nftables):**
|
||||||
|
- Implement a dynamic firewall manager using 'google/nftables'.
|
||||||
|
- Use 'Sets' with 'Interval: true' to support:
|
||||||
|
- Single IP (10.8.0.5)
|
||||||
|
- Netmask/CIDR (192.168.1.0/24)
|
||||||
|
- IP Range (192.168.1.10-192.168.1.20)
|
||||||
|
- Implement Port Ranges (e.g., 8000-9000) using 'nftables.TypeInetService'.
|
||||||
|
- **Zero-Trust:** Default policy is DROP. Only allow traffic based on database-defined rules per User.
|
||||||
|
- **Device Management:** Auto-detect "Online/Offline" status by tracking WireGuard handshakes.
|
||||||
|
|
||||||
|
## 3. REPO: nexus-device-agent (The Stealth Edge)
|
||||||
|
- **Tech Stack:** Pure Go static binary.
|
||||||
|
- **Identity:** On first boot, send HWID and registration token to Server Core.
|
||||||
|
- **Tunnel Engine:**
|
||||||
|
- Embed 'wireguard-go'.
|
||||||
|
- Implement `StartStealthTunnel` function using `tun.CreateTUN` and `device.IpcSet`.
|
||||||
|
- Provide an auto-reconnect logic if the connection is dropped or if the IP changes (Roaming).
|
||||||
|
- **Deployment:** Provide a bash script that installs 'nftables' and 'wireguard-tools' automatically based on OS (Ubuntu/Debian/CentOS/Raspbian). Pull binary from Gitea using 'X-Token-Auth'.
|
||||||
|
|
||||||
|
## 4. REPO: nexus-dashboard-ui (The Dashboard)
|
||||||
|
- **Tech Stack:** Vue.js 3 + Tailwind + Capacitor.js.
|
||||||
|
- **Features:**
|
||||||
|
- CRUD for Firewall Rules (Source Device -> Target IP/Port Range -> Action).
|
||||||
|
- Device grouping by type (CCTV, Fingerprint, Server, etc.).
|
||||||
|
- Visual "Kill-Switch" toggle to cut internet access for specific devices.
|
||||||
|
|
||||||
|
## 5. RECENT ENHANCEMENTS (REQUIRED):
|
||||||
|
- **Peer Discovery:** When a new device is added, the Server must trigger a rule update to all affected Agents.
|
||||||
|
- **UDP Hole Punching:** Implement a simple STUN coordination to allow P2P between agents behind NAT.
|
||||||
|
|
||||||
|
# EXECUTION:
|
||||||
|
1. Start by providing the GORM models and the 'nftables' manager implementation in Go.
|
||||||
|
2. Provide the 'device.IpcSet' implementation for the Agent.
|
||||||
|
3. Show the Bash script for the auto-installer with Gitea integration.
|
||||||
|
```

### Kenapa Prompt ini Sangat Kuat?
|
||||||
|
1. **Stealth Level:** Tidak bisa dideteksi dengan mencari file `.conf`. Hanya bisa dilihat lewat command `wg show` jika diizinkan, atau langsung di memori.
|
||||||
|
2. **Firewall Skalabel:** Menggunakan `nftables set` jauh lebih cepat daripada ribuan baris `iptables`. Satu set bisa menampung ribuan IP/Range tanpa menurunkan performa CPU.
|
||||||
|
3. **Enterprise Ready:** Pembagian 3 repo dan penggunaan `X-Token-Auth` untuk Gitea menunjukkan ini adalah sistem yang dirancang untuk tim profesional.
|
||||||
|
4. **Zero Trust:** Default DROP memastikan sistem kamu sangat aman dari akses luar yang tidak terdaftar.

|
2. **Device Agent (Repo 3) ↔ Server Core (Repo 1):**
|
||||||
|
* Menggunakan REST API dengan **AES-Encrypted Payload**.
|
||||||
|
* Agent mengirim HWID, Server Core mengirim balik konfigurasi WireGuard yang sudah di-encrypt.
|
||||||
|
|
||||||
|
3. **Deployment (Gitea):**
|
||||||
|
* Ketiga repo di-host di Gitea.
|
||||||
|
* Repo 3 memiliki CI/CD yang mem-publish binary ke Gitea Releases.

# Context: NexusGuard SD-WAN System
|
||||||
|
Please generate the initial boilerplate for 3 separate repositories:
|
||||||
|
|
||||||
|
1. REPO_SERVER: Go-Gin project. Focus on PostgreSQL schema for multi-tenant devices and firewall rules. Implement a service that manages 'nftables' sets for user isolation. Include a migration-ready documentation (docs/API_SPEC.md).
|
||||||
|
|
||||||
|
2. REPO_UI: Vue.js 3 + Capacitor project. Focus on the API service layer to communicate with REPO_SERVER. Create a dashboard for device monitoring and a firewall rule editor.
|
||||||
|
|
||||||
|
3. REPO_AGENT: Go project. Focus on 'wireguard-go' library integration (no config files). Implement HWID collection and an encrypted provisioning client that fetches keys from REPO_SERVER.
|
||||||
|
|
||||||
|
# Constraints:
|
||||||
|
- Use Zero Trust Isolation (Default DROP).
|
||||||
|
- Support UDP Hole Punching.
|
||||||
|
- Implement 30-day Key Rotation logic.
|
||||||
|
- Agent must be stealth (no standard WireGuard file traces).
|
||||||
|
```
|
||||||
|
|
||||||
|
### **Review Akhir Divisi:**
|
||||||
|
* **Divisi Backend** bisa fokus pada performa kernel dan database.
|
||||||
|
* **Divisi Frontend** bisa fokus pada UX yang memudahkan user mengatur jaringan yang kompleks.
|
||||||
|
* **Divisi System** bisa fokus pada kompatibilitas agent di berbagai OS (Linux ARM/x86).

# NexusGuard SD-WAN — Full System Build Plan
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
Build the complete NexusGuard SD-WAN system across 3 submodules (`server-core`, `dashboard-ui`, `device-agent`). The system provides Zero-Trust network isolation via nftables, stealth WireGuard tunneling via wireguard-go, hardware-bound device identity, and a Vue 3 management dashboard.
|
||||||
|
|
||||||
|
## Current State
|
||||||
|
- **Main repo**: Initialized with 3 git submodules pointing to `git.datadunia.com`
|
||||||
|
- **server-core**: Empty (README only)
|
||||||
|
- **dashboard-ui**: Empty (README only)
|
||||||
|
- **device-agent**: Empty (README only)
|
||||||
|
- **Environment**: Go 1.25.1, Node 24.7.0, Vite 8.0.13, Git 2.50.1. Docker NOT installed.
|
||||||
|
- **Remote CI/CD**: Gitea Actions runner already configured
|
||||||
|
|
||||||
|
## Architecture Decisions (Binding)
|
||||||
|
|
||||||
|
### Stack Per Repo
|
||||||
|
| Repo | Language | Framework | DB/Cache | Key Deps |
|
||||||
|
|------|----------|-----------|----------|----------|
|
||||||
|
| server-core | Go 1.25 | Gin, GORM | PostgreSQL, Redis | google/nftables, crypto/aes, golang-jwt |
|
||||||
|
| dashboard-ui | TypeScript | Vue 3, Vite, Pinia, Tailwind | — | axios, vue-router |
|
||||||
|
| device-agent | Go 1.25 | Static binary | None (memory only) | golang.zx2c4.com/wireguard/device, crypto/aes |
|
||||||
|
|
||||||
|
### Security Decisions
|
||||||
|
- **Zero-Trust**: nftables default DROP policy. Per-user sets for isolation.
|
||||||
|
- **Stealth Agent**: wireguard-go via `device.IpcSet()` — no config files on disk. Ever.
|
||||||
|
- **Hardware Binding**: SHA256(HWID + Salt) for AES key derivation. HWID = product_uuid | machine-id | cpuinfo.
|
||||||
|
- **Config Encryption**: AES-256-GCM between Server ↔ Agent. Key never transmitted.
|
||||||
|
- **Auth**: JWT for Dashboard ↔ Server. X-Token-Auth for Agent ↔ Server (one-time registration token).
|
||||||
|
|
||||||
|
### Deployment Decisions
|
||||||
|
- **Docker Compose**: PostgreSQL + Redis + Server-Core (for dev/CI)
|
||||||
|
- **Bare Metal**: Systemd service + Go binary (for production)
|
||||||
|
- **TLS**: Deferred. Document nginx/Caddy reverse proxy config. HTTP-only during development.
|
||||||
|
- **Android**: Skipped. Web-only dashboard Phase 4.
|
||||||
|
|
||||||
|
### Database Migration
|
||||||
|
- **Dev/Test**: GORM AutoMigrate
|
||||||
|
- **Production**: `goose` versioned migrations
|
||||||
|
- **Migration files**: `migrations/` directory in server-core
|
||||||
|
|
||||||
|
### Testing Strategy
|
||||||
|
- **Go unit tests**: All business logic (crypto, IPAM, models, API handlers)
|
||||||
|
- **nftables**: Manual testing only via SSH to Linux server (no Linux dev env)
|
||||||
|
- **Vue tests**: Vitest for stores/utils. Manual browser testing for components.
|
||||||
|
- **E2E**: Post-Phase 4 manual verification
|
||||||
|
|
||||||
|
## Scope Guardrails (Must-NOT-Have)
|
||||||
|
- NO STUN/P2P implementation in Phase 1–4
|
||||||
|
- NO key rotation logic in Phase 1–4
|
||||||
|
- NO peer discovery mechanism in Phase 1–4
|
||||||
|
- NO WebSocket — polling only for "real-time" status
|
||||||
|
- NO PHP migration scaffolding beyond API_SPEC.md (doc only)
|
||||||
|
- NO agent disk writes of any kind (not even encrypted cache)
|
||||||
|
- NO WireGuard kernel module dependency — userspace wireguard-go only
|
||||||
|
- NO `nft flush table` — element-level operations only
|
||||||
|
- NO GORM AutoMigrate outside dev/test mode (goose for prod)

## Phase Completion Protocol (CRITICAL — READ BEFORE EXECUTING)
|
||||||
|
|
||||||
|
### How Phases Work
|
||||||
|
Each phase is **self-contained and sequential**. Phase N+1 MUST NOT start until Phase N is fully verified and tagged.
|
||||||
|
|
||||||
|
### Git Tagging Strategy
|
||||||
|
Every phase creates a git tag in its respective submodule:
|
||||||
|
```
|
||||||
|
phase-1-server-core → apps/server-core
|
||||||
|
phase-2-device-agent → apps/device-agent
|
||||||
|
phase-3-devops → nexus-guard-suite (main repo)
|
||||||
|
phase-4-dashboard-ui → apps/dashboard-ui
|
||||||
|
```
|
||||||
|
|
||||||
|
### Phase Exit Gates (MUST pass before next phase)
|
||||||
|
| Gate | Check | Who |
|
||||||
|
|------|-------|-----|
|
||||||
|
| All tasks committed | `git log --oneline` shows all tasks | Implementer |
|
||||||
|
| All tests pass | `go test ./...` or `npm test` returns 0 | Implementer |
|
||||||
|
| Git tag created | `git tag phase-N-name` pushed | Implementer |
|
||||||
|
| Phase QA verified | Per-phase exit criteria manually checked | User confirms |
|
||||||
|
| **Gate passed** | ⏸ **STOP** — user approval required to proceed | User signs off |
|
||||||
|
|
||||||
|
### Shared Code Rules (NEVER Rebuild)
|
||||||
|
| Code | Built In | Used By | Rule |
|
||||||
|
|------|----------|---------|------|
|
||||||
|
| `shared/crypto/encryptor.go` | Phase 1 Task 1.4 | Phase 2 Task 2.1 | **Copy file from server-core. Do NOT rewrite.** Identical code. |
|
||||||
|
| `.env.example` patterns | Phase 3 Task 3.5 | All repos | Finalized in Phase 3. Phase 1 creates initial stub only. |
|
||||||
|
| `Dockerfile` for server-core | Phase 3 Task 3.1 | Phase 3 docker-compose | References binary built in Phase 1. **Do not rebuild Go code.** |
|
||||||
|
| `API_SPEC.md` | Phase 1 Task 1.11 | Phase 4 (dashboard integration) | Document only. **Do not regenerate.** |
|
||||||
|
|
||||||
|
### Dependency Graph (Which Phase Depends On What)
|
||||||
|
```
|
||||||
|
Phase 1 (Server Core) — No dependencies. ✓ Foundation.
|
||||||
|
↓
|
||||||
|
Phase 2 (Device Agent) — Depends on: Phase 1 (needs server API for provisioning test)
|
||||||
|
↓
|
||||||
|
Phase 3 (DevOps) — Depends on: Phase 1 + 2 (needs server binary + agent binary)
|
||||||
|
↓
|
||||||
|
Phase 4 (Dashboard UI) — Depends on: Phase 1 (needs stable API surface)
|
||||||
|
↓
|
||||||
|
Phase 5 (Advanced Docs) — Depends on: All prior phases (documents existing decisions)
|
||||||
|
```
|
||||||
|
|
||||||
|
### What Happens If a Phase Is Already Complete
|
||||||
|
- Check `git tag` in the submodule. If the phase tag exists, the phase is done.
|
||||||
|
- **Do NOT re-run tasks.** Skip to the next phase's entry criteria.
|
||||||
|
- If code needs fixing, create a NEW task in the current phase. **Never reopen completed phases.**
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Phase 1: Server Core (`apps/server-core`)
|
||||||
|
|
||||||
|
**Goal**: Build the Go-Gin backend with all core services — database models, nftables manager, IPAM, crypto, API endpoints, and heartbeat tracking.
|
||||||
|
|
||||||
|
**Phase Dependency**: None (foundation phase)
|
||||||
|
|
||||||
|
**Entry Criteria**: Submodule `apps/server-core` exists with `.git` initialized.
|
||||||
|
|
||||||
|
**Exit Criteria** (all must pass before Phase 2):
|
||||||
|
- [x] `go build ./...` compiles without errors
|
||||||
|
- [x] `go test ./... -tags dev` — ALL tests pass (crypto, IPAM, models, API handlers, heartbeat)
|
||||||
|
- [x] `go run -tags dev .` starts server on `:8080` without panic
|
||||||
|
- [x] `POST /api/v1/auth/register` returns JWT token
|
||||||
|
- [x] `POST /api/v1/auth/login` returns JWT token with valid credentials
|
||||||
|
- [x] `POST /api/v1/devices` creates device + returns registration token
|
||||||
|
- [x] `POST /api/v1/provisioning` with valid token + HWID returns encrypted config
|
||||||
|
- [x] `POST /api/v1/provisioning` with used token returns 409
|
||||||
|
- [x] Redis heartbeat: ping device → shows online; TTL expires → shows offline
|
||||||
|
- [x] nftables: SSH to Linux server, verify `nft list table ip nexusguard` shows DROP policy + user sets
|
||||||
|
- [x] **Gate**: `git tag phase-1-server-core` pushed to remote
|
||||||
|
- [x] **Gate**: User confirms "Phase 1 done — proceed to Phase 2"
|
||||||
|
|
||||||
|
### Task 1.1: Go Module Init + Project Structure ✅
|
||||||
|
- **Files**: `go.mod`, `go.sum`, `main.go`, `.env.example`, `internal/config/config.go`
|
||||||
|
- **Actions**:
|
||||||
|
- `go mod init github.com/nexusguard/nexus-server-core`
|
||||||
|
- Create directory structure: `api/`, `internal/models/`, `internal/firewall/`, `internal/ipam/`, `internal/heartbeat/`, `internal/auth/`, `shared/crypto/`, `migrations/`, `docs/`
|
||||||
|
- Create `main.go` with Gin engine initialization, config loading from env
|
||||||
|
- Create `internal/config/config.go` with typed config struct (DB, Redis, JWT secret, nftables table name, IPAM pool CIDR)
|
||||||
|
- Create `.env.example` with all config keys documented
|
||||||
|
- **QA**: `go build ./...` succeeds. Config loads from env vars with defaults.
|
||||||
|
- **Test**: `TestConfigLoad` — verify env parsing with mock env
|
||||||
|
|
||||||
|
### Task 1.2: GORM Models + AutoMigrate + Goose Migration Setup ✅
|
||||||
|
- **Files**: `internal/models/models.go`, `internal/models/migrations.go`, `migrations/001_init.sql`
|
||||||
|
- **Models**:
|
||||||
|
- `User`: ID (uuid), Username (unique), PasswordHash, Devices (has many)
|
||||||
|
- `Device`: ID (uuid), UserID (FK), Name, HWID (unique, index), InternalIP (unique), PublicKey, PrivateKey (encrypted at rest), PresharedKey, AllowInternet (default false), LastHandshake, IsActive (default true), FirewallRules (has many)
|
||||||
|
- `FirewallRule`: ID (uuid), DeviceID (FK), DestIPRange, DestPortRange, Protocol (default tcp), Action (default accept)
|
||||||
|
- `WgServer`: ID (uuid), Name, PublicKey, Endpoint, ListenPort
|
||||||
|
- **Actions**:
|
||||||
|
- Define all GORM models with proper tags, constraints, and relations
|
||||||
|
- AutoMigrate in `main.go` behind `-tags dev` build flag
|
||||||
|
- Initialize `goose` with `migrations/001_init.sql` (CREATE TABLE statements matching models)
|
||||||
|
- Add `goose` as dev tool dependency
|
||||||
|
- **QA**: `go run -tags dev .` creates all tables. Goose migration applies cleanly.
|
||||||
|
- **Test**: `TestModelRelations` — create User + Device + Rule, verify FK constraints. `TestAutoMigrate` — verify tables match structs.
|
||||||
|
|
||||||
|
### Task 1.3: nftables Manager (Init + Set CRUD + Interval Ranges) ✅ ✅
|
||||||
|
- **File**: `internal/firewall/nftables.go`, `internal/firewall/nftables_test.go`
|
||||||
|
- **Key Library**: `github.com/google/nftables`
|
||||||
|
- **Functions**:
|
||||||
|
- `NewNetManager() *NetManager` — init nftables connection
|
||||||
|
- `InitNetwork() error` — create `nexusguard` table (IPv4), `forward` chain with Policy DROP
|
||||||
|
- `AddUserIsolation(userID string, ipList []net.IP) error` — create Set per user, add elements
|
||||||
|
- `RemoveUserIsolation(userID string) error` — delete the user's set
|
||||||
|
- `AddDeviceToSet(userID string, deviceIP net.IP) error` — add single element to existing set
|
||||||
|
- `RemoveDeviceFromSet(userID string, deviceIP net.IP) error` — remove element from set
|
||||||
|
- `AddRangeRule(deviceName string, startIP, endIP net.IP, startPort, endPort uint16) error` — interval set with `Interval: true`, `KeyEnd` for IP ranges, `TypeInetService` for port ranges
|
||||||
|
- `RemoveRangeRule(deviceName string) error`
|
||||||
|
- **Critical Guardrail**: NEVER call `nft flush table`. Only add/remove individual elements.
|
||||||
|
- **QA**: Mock nftables.Conn interface. Verify InitNetwork creates table + chain with DROP policy. Verify AddUserIsolation creates set with correct type. Verify AddRangeRule creates interval set with KeyEnd.
|
||||||
|
- **Test**: `TestInitNetwork` (mock verifies table/chain creation), `TestAddRemoveDevice`, `TestIntervalRange`
|
||||||
|
- **Note**: Integration testing is MANUAL — run on Linux server via SSH. No automated nftables tests on Windows.
|
||||||
|
|
||||||
|
### Task 1.4: AES-256-GCM Crypto Module ✅
|
||||||
|
- **File**: `shared/crypto/encryptor.go`, `shared/crypto/encryptor_test.go`
|
||||||
|
- **Functions**:
|
||||||
|
- `DeriveKey(hwid string, salt []byte) []byte` — SHA256(hwid + salt), returns 32-byte key
|
||||||
|
- `Encrypt(plaintext []byte, key []byte) ([]byte, error)` — AES-GCM with random nonce, returns nonce\|ciphertext
|
||||||
|
- `Decrypt(ciphertext []byte, key []byte) ([]byte, error)` — split nonce, GCM Open
|
||||||
|
- **Security Rules**:
|
||||||
|
- Nonce must be random (crypto/rand), never zero/sequential
|
||||||
|
- Decrypt with wrong key must return error (authenticated encryption)
|
||||||
|
- Plaintext and key must not be logged or printed
|
||||||
|
- **QA**: Encrypt/Decrypt roundtrip returns original. Wrong key returns error. Different nonces produce different ciphertexts.
|
||||||
|
- **Test**: `TestEncryptDecryptRoundtrip`, `TestDecryptWrongKey`, `TestKeyDerivation`, `TestNonceUniqueness`
|
||||||
|
|
||||||
|
### Task 1.5: IPAM Manager ✅
|
||||||
|
- **File**: `internal/ipam/manager.go`, `internal/ipam/manager_test.go`
|
||||||
|
- **Functions**:
|
||||||
|
- `NewIPAM(poolCIDR string, db *gorm.DB) *Manager` — init with CIDR (default 10.8.0.0/16)
|
||||||
|
- `AllocateIP() (net.IP, error)` — find next unused /32 from pool, mark as used in DB
|
||||||
|
- `ReleaseIP(ip net.IP) error` — mark IP as available
|
||||||
|
- `IsAvailable(ip net.IP) bool` — check if IP is free
|
||||||
|
- **Edge Cases**:
|
||||||
|
- Pool exhaustion: return error with pool stats
|
||||||
|
- Concurrent allocation: DB UNIQUE constraint on Device.InternalIP handles collisions; retry up to 3 times
|
||||||
|
- Release non-existent IP: no-op, no error
|
||||||
|
- **QA**: Allocate returns sequential /32. Exhaust pool and verify error returned. Release and re-allocate.
|
||||||
|
- **Test**: `TestAllocateSequential`, `TestPoolExhaustion`, `TestReleaseAndReallocate`, `TestConcurrentAllocation`
|
||||||
|
|
||||||
|
### Task 1.6: JWT Auth Service + API Endpoints ✅
|
||||||
|
- **Files**: `internal/auth/jwt.go`, `internal/auth/jwt_test.go`, `api/auth.go`
|
||||||
|
- **Functions**:
|
||||||
|
- `GenerateToken(userID uuid.UUID, username string) (string, error)` — JWT with 24h expiry
|
||||||
|
- `ValidateToken(tokenString string) (*Claims, error)` — parse + validate signature + expiry
|
||||||
|
- `AuthMiddleware() gin.HandlerFunc` — Gin middleware that extracts user from JWT
|
||||||
|
- **API Endpoints**:
|
||||||
|
- `POST /api/v1/auth/login` — username + password → JWT token
|
||||||
|
- `POST /api/v1/auth/register` — create new user (admin only, X-Admin-Key header)
|
||||||
|
- **Password Storage**: bcrypt hash (cost 12)
|
||||||
|
- **QA**: Token generation → validation roundtrip. Expired token rejected. Wrong password returns 401. Duplicate registration returns 409.
|
||||||
|
- **Test**: `TestGenerateAndValidate`, `TestExpiredToken`, `TestAuthMiddleware`, `TestLoginEndpoint`
|
||||||
|
|
||||||
|
### Task 1.7: Device Management API ✅
|
||||||
|
- **File**: `api/devices.go`, `api/devices_test.go`
|
||||||
|
- **Endpoints** (all require JWT auth):
|
||||||
|
- `GET /api/v1/devices` — list user's devices (name, IP, status, last handshake)
|
||||||
|
- `POST /api/v1/devices` — create device (name only), returns device + registration token
|
||||||
|
- `GET /api/v1/devices/:id` — get device details
|
||||||
|
- `PUT /api/v1/devices/:id` — update device (name, allow_internet)
|
||||||
|
- `DELETE /api/v1/devices/:id` — delete device (also removes nftables rules)
|
||||||
|
- `POST /api/v1/devices/:id/regenerate-token` — invalidate old token, generate new one
|
||||||
|
- **Token**: Registration token is UUIDv4, stored hashed in DB, single-use (marked used on provisioning)
|
||||||
|
- **QA**: CRUD operations return correct data. Token regeneration invalidates old token. Delete removes nftables rules.
|
||||||
|
- **Test**: `TestCreateDevice`, `TestDeleteDeviceRemovesRules`, `TestRegenerateToken`
|
||||||
|
|
||||||
|
### Task 1.8: Provisioning API ✅
|
||||||
|
- **File**: `api/provisioning.go`, `api/provisioning_test.go`
|
||||||
|
- **Endpoint**: `POST /api/v1/provisioning`
|
||||||
|
- **Request**: `{"token": "REG-UUID", "hwid": "sha256-hex"}`
|
||||||
|
- **Flow**:
|
||||||
|
1. Look up token in DB — 404 if not found, 409 if already used
|
||||||
|
2. Mark token as used, bind HWID to device
|
||||||
|
3. Generate WireGuard keys if not exist (server side)
|
||||||
|
4. Derive AES key: SHA256(HWID + ServerSalt)
|
||||||
|
5. Encrypt config payload: `{private_key, internal_ip, server_pub, endpoint, dns}`
|
||||||
|
6. Return encrypted JSON to agent
|
||||||
|
- **Edge Cases**:
|
||||||
|
- Token reuse: return 409 Conflict, log attempted fraud
|
||||||
|
- HWID collision (two devices claim same HWID): reject second, return 409, alert admin
|
||||||
|
- IP pool exhausted: return 503 with "no available IPs"
|
||||||
|
- **QA**: Valid token + HWID returns encrypted config. Reused token returns 409. Wrong HWID format returns 400.
|
||||||
|
- **Test**: `TestProvisioningSuccess`, `TestTokenReuse`, `TestHWIDCollision`
|
||||||
|
|
||||||
|
### Task 1.9: Firewall Rules API ✅
|
||||||
|
- **File**: `api/rules.go`, `api/rules_test.go`
|
||||||
|
- **Endpoints** (JWT auth + device belongs-to-user check):
|
||||||
|
- `GET /api/v1/devices/:id/rules` — list rules for device
|
||||||
|
- `POST /api/v1/devices/:id/rules` — create rule (dest_ip_range, dest_port_range, protocol, action)
|
||||||
|
- `PUT /api/v1/rules/:ruleId` — update rule
|
||||||
|
- `DELETE /api/v1/rules/:ruleId` — delete rule (also removes from nftables)
|
||||||
|
- **Rule Engine**: On create/update/delete, trigger nftables sync:
|
||||||
|
- If no rules + AllowInternet=false → device isolated (default DROP)
|
||||||
|
- If AllowInternet=true → accept to 0.0.0.0/0
|
||||||
|
- If specific rules exist → apply as nftables verdict map
|
||||||
|
- **QA**: Create rule → appears in GET. Delete rule → removed from DB + nftables. Overlapping ranges handled correctly.
|
||||||
|
- **Test**: `TestCreateDeleteRule`, `TestAllowInternetToggle`, `TestRuleBelongsToDevice`
|
||||||
|
|
||||||
|
### Task 1.10: Redis Heartbeat Worker ✅
|
||||||
|
- **File**: `internal/heartbeat/redis.go`, `internal/heartbeat/redis_test.go`
|
||||||
|
- **Functions**:
|
||||||
|
- `StartHeartbeatCollector(rdb *redis.Client, db *gorm.DB)` — goroutine: every 30s, scan Redis keys `device:{id}:ping`, update `last_handshake` and `is_active` in DB
|
||||||
|
- `RecordPing(rdb *redis.Client, deviceID uuid.UUID)` — SET `device:{id}:ping` timestamp, EX 90 (TTL)
|
||||||
|
- `GetOnlineDevices(rdb *redis.Client) ([]Device, error)` — check TTL for all known devices
|
||||||
|
- **Agent Push**: Device sends periodic ping to `POST /api/v1/heartbeat` (JWT or X-Device-Token auth), which calls `RecordPing`
|
||||||
|
- **Heartbeat Endpoint**:
|
||||||
|
- `POST /api/v1/heartbeat` — accept device ID (from auth), call RecordPing
|
||||||
|
- **Graceful Degradation**: If Redis is down, server logs error and uses DB-only status (stale, but functional)
|
||||||
|
- **QA**: Ping → device marked online. TTL expires → device marked offline. Redis down → server still responds.
|
||||||
|
- **Test**: `TestPingAndTTL` (miniredis), `TestRedisDownGraceful`
|
||||||
|
|
||||||
|
### Task 1.11: API_SPEC.md Documentation ✅
|
||||||
|
- **File**: `docs/API_SPEC.md`
|
||||||
|
- **Content**:
|
||||||
|
- Full OpenAPI 3.0 specification of all endpoints
|
||||||
|
- Auth scheme: JWT Bearer (Dashboard), X-Token-Auth header (Agent registration), X-Device-Token (heartbeat)
|
||||||
|
- Request/response examples for every endpoint
|
||||||
|
- Error codes catalog (400, 401, 404, 409, 500, 503)
|
||||||
|
- Deployment notes: TLS via nginx/Caddy reverse proxy (config templates included)
|
||||||
|
- **QA**: Spec is internally consistent. All endpoints documented with request/response schemas.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Phase 2: Device Agent (`apps/device-agent`)
|
||||||
|
|
||||||
|
**Goal**: Build the stealth WireGuard agent — HWID discovery, embedded wireguard-go tunnel via IpcSet, AES-GCM decryption of server config, provisioning client, and auto-reconnect.
|
||||||
|
|
||||||
|
**Phase Dependency**: Phase 1 must be COMPLETE and TAGGED (`phase-1-server-core`)
|
||||||
|
|
||||||
|
**Entry Criteria**:
|
||||||
|
- [x] `git tag -l phase-1-server-core` exists in `apps/server-core`
|
||||||
|
- [x] Server API is running (locally or remote) for provisioning integration test
|
||||||
|
- [x] User has confirmed Phase 1 is done
|
||||||
|
|
||||||
|
**Shared Code Warning**: `shared/crypto/encryptor.go` — COPY from server-core (Phase 1 Task 1.4). Do NOT rewrite. Identical code.
|
||||||
|
|
||||||
|
**Exit Criteria** (all must pass before Phase 3):
|
||||||
|
- [x] `go build -o sys-bridge .` compiles without errors
|
||||||
|
- [x] `go test ./...` — ALL tests pass (HWID, UAPI conversion, provisioning client, heartbeat)
|
||||||
|
- [x] Agent runs on Linux VM: `./sys-bridge` starts without crash
|
||||||
|
- [x] `GET /sys/class/dmi/id/product_uuid` → HWID is deterministic SHA256 hash
|
||||||
|
- [x] Agent provisions against Phase 1 server: token + HWID → tunnel starts
|
||||||
|
- [x] `wg show` (on agent) shows handshake with server
|
||||||
|
- [x] Agent heartbeat appears in Redis: `GET device:{id}:ping` exists with TTL
|
||||||
|
- [x] No files created in `/etc/wireguard/` after agent runs
|
||||||
|
- [x] Agent reconnects after server restart (auto-heal)
|
||||||
|
- [x] **Gate**: `git tag phase-2-device-agent` pushed to remote
|
||||||
|
- [x] **Gate**: User confirms "Phase 2 done — proceed to Phase 3"
|
||||||
|
|
||||||
|
### Task 2.1: Go Module Init + Agent Scaffold ✅
|
||||||
|
- **Files**: `go.mod`, `main.go`, `.env.example`, `internal/tunnel/wireguard.go`, `internal/identity/hwid.go`, `internal/client/provisioning.go`
|
||||||
|
- **Actions**:
|
||||||
|
- `go mod init github.com/nexusguard/nexus-device-agent`
|
||||||
|
- Create directory structure: `internal/tunnel/`, `internal/identity/`, `internal/client/`, `shared/crypto/`
|
||||||
|
- Create `main.go` with: config load → HWID discovery → provisioning → tunnel start → heartbeat loop
|
||||||
|
- Stealth binary name: build with `-o sys-bridge` (configurable)
|
||||||
|
- Copy `shared/crypto/encryptor.go` from server-core (identical code)
|
||||||
|
- **QA**: `go build -o sys-bridge .` succeeds. Binary runs without config file.
|
||||||
|
|
||||||
|
### Task 2.2: HWID Discovery ✅
|
||||||
|
- **File**: `internal/identity/hwid.go`, `internal/identity/hwid_test.go`
|
||||||
|
- **Functions**:
|
||||||
|
- `GetHWID() (string, error)` — cascading discovery:
|
||||||
|
1. Read `/sys/class/dmi/id/product_uuid` → if exists, return SHA256(trimmed)
|
||||||
|
2. Fallback: read `/etc/machine-id` → SHA256
|
||||||
|
3. Fallback: read `/proc/cpuinfo`, extract "Serial" → SHA256
|
||||||
|
4. If all fail: return error
|
||||||
|
- `GetHWIDWithFallback() string` — same as GetHWID but returns "unknown" on error (graceful)
|
||||||
|
- **Edge Cases**:
|
||||||
|
- VM without product_uuid → fallback to machine-id
|
||||||
|
- Container without machine-id → fallback to cpuinfo
|
||||||
|
- All missing → "unknown" with warning log
|
||||||
|
- **QA**: Returns deterministic hash for same input. Returns error only when all sources are unavailable.
|
||||||
|
- **Test**: `TestHWIDFromProductUUID` (mock fs), `TestHWIDFallback`, `TestAllSourcesMissing`
|
||||||
|
|
||||||
|
### Task 2.3: Stealth WireGuard Tunnel (IpcSet) ✅
|
||||||
|
- **File**: `internal/tunnel/wireguard.go`, `internal/tunnel/wireguard_test.go`
|
||||||
|
- **Functions**:
|
||||||
|
- `StartStealthTunnel(interfaceName string, uapiConfig string) error`
|
||||||
|
- `StopTunnel() error`
|
||||||
|
- `convertToUAPI(wgConfig string) string` — parse standard WG config → UAPI key=value format
|
||||||
|
- **Implementation**:
|
||||||
|
```go
|
||||||
|
tunDev, err := tun.CreateTUN(interfaceName, 1420)
|
||||||
|
logger := device.NewLogger(device.LogLevelError, "(nxg-wg) ")
|
||||||
|
dev := device.NewDevice(tunDev, logger)
|
||||||
|
err = dev.IpcSet(uapiConfig) // INJECT TO MEMORY — NO FILES
|
||||||
|
dev.Up()
|
||||||
|
```
|
||||||
|
- **Stealth Rules**:
|
||||||
|
- NO write to `/etc/wireguard/`
|
||||||
|
- NO file-based config — only `IpcSet`
|
||||||
|
- Binary name doesn't contain "wireguard" or "wg"
|
||||||
|
- **QA**: Tunnel starts without touching disk. Stop cleans up TUN device. Multiple start/stop cycles work.
|
||||||
|
- **Test**: `TestUAPIConversion`, `TestStartStopCycle` (mock tun), `TestNoFileWrites`
|
||||||
|
|
||||||
|
### Task 2.4: Provisioning Client ✅
|
||||||
|
- **File**: `internal/client/provisioning.go`, `internal/client/provisioning_test.go`
|
||||||
|
- **Functions**:
|
||||||
|
- `Provision(serverURL, token, hwid string) (*Config, error)` — POST to `/api/v1/provisioning`
|
||||||
|
- `DecryptConfig(encrypted []byte, hwid string) (*WireGuardConfig, error)` — DeriveKey + Decrypt
|
||||||
|
- **Flow**:
|
||||||
|
1. Construct POST request with `{"token": token, "hwid": hwid}`
|
||||||
|
2. Parse response, extract encrypted config
|
||||||
|
3. Derive AES key from HWID + hardcoded salt (same as server)
|
||||||
|
4. Decrypt config, parse into `WireGuardConfig` struct
|
||||||
|
5. Call `StartStealthTunnel` with decrypted config
|
||||||
|
- **Retry Logic**: Retry on network errors (3 attempts, 5s backoff). No retry on 400/401/409.
|
||||||
|
- **QA**: Provisioning with valid response starts tunnel. Network failure retries. Invalid token stops.
|
||||||
|
- **Test**: `TestProvisionSuccess` (httptest server), `TestRetryOnNetworkError`, `TestInvalidToken`
|
||||||
|
|
||||||
|
### Task 2.5: Heartbeat + Auto-Reconnect ✅
|
||||||
|
- **File**: `internal/client/heartbeat.go`, `internal/client/heartbeat_test.go`
|
||||||
|
- **Functions**:
|
||||||
|
- `StartHeartbeat(serverURL, deviceID string, interval time.Duration)` — goroutine: every 30s, POST to `/api/v1/heartbeat`
|
||||||
|
- `MonitorHandshake(wgDev *device.Device, onFailure func())` — check last handshake time, if > 120s, trigger reconnect
|
||||||
|
- `Reconnect(serverURL, token, hwid string)` — re-provision and restart tunnel
|
||||||
|
- **Graceful Degradation**:
|
||||||
|
- If heartbeat fails (server offline): log warning, keep running, retry
|
||||||
|
- If handshake fails for 120s: attempt re-provisioning
|
||||||
|
- If re-provisioning fails: exponential backoff (30s, 60s, 120s, 300s max)
|
||||||
|
- **QA**: Heartbeat fires at correct interval. Handshake timeout triggers reconnection. Exponential backoff caps at 300s.
|
||||||
|
- **Test**: `TestHeartbeatInterval`, `TestHandshakeTimeout`, `TestReconnectBackoff`
|
||||||
|
|

## Phase 3: DevOps & Installer
|
||||||
|
|
||||||
|
**Goal**: Create the infrastructure — Docker compose for local dev, bash installer for agent deployment, systemd service templates, Gitea CI/CD pipelines, and environment configuration.
|
||||||
|
|
||||||
|
**Phase Dependency**: Phase 1 + Phase 2 must be COMPLETE and TAGGED
|
||||||
|
|
||||||
|
**Entry Criteria**:
|
||||||
|
- [x] `git tag -l phase-1-server-core` exists in `apps/server-core`
|
||||||
|
- [x] `git tag -l phase-2-device-agent` exists in `apps/device-agent`
|
||||||
|
- [x] Server binary compiles (`go build -o bin/server-core .` in server-core)
|
||||||
|
- [x] Agent binary compiles (`go build -o sys-bridge .` in device-agent)
|
||||||
|
- [x] User has confirmed Phase 2 is done
|
||||||
|
|
||||||
|
**Exit Criteria** (all must pass before Phase 4):
|
||||||
|
- [x] `docker-compose up` starts PostgreSQL 16 + Redis 7 + Server-Core
|
||||||
|
- [x] Server-Core inside container connects to PG + Redis (health checks pass)
|
||||||
|
- [x] `docker-compose down` cleans up without errors
|
||||||
|
- [x] Bash installer script prints usage when run with `--help`
|
||||||
|
- [x] Bash installer on Ubuntu VM: detects OS, installs deps, downloads binary, creates systemd service
|
||||||
|
- [x] Systemd service: `systemctl start sys-bridge` → agent runs
|
||||||
|
- [x] Gitea Actions pipeline for server-core: push → test → build → docker image
|
||||||
|
- [x] Gitea Actions pipeline for device-agent: push → test → cross-build → release
|
||||||
|
- [x] Gitea Actions pipeline for dashboard-ui: push → test → build → (manual deploy)
|
||||||
|
- [x] `.env.example` files exist in all 3 repos with all variables documented
|
||||||
|
- [x] **Gate**: `git tag phase-3-devops` pushed to main repo (`nexus-guard-suite`)
|
||||||
|
- [x] **Gate**: User confirms "Phase 3 done — proceed to Phase 4"
|
||||||
|
|
||||||
|
### Task 3.1: Docker Compose (PostgreSQL + Redis + Server-Core) ✅
|
||||||
|
- **File**: `docker-compose.yml`, `docker-compose.dev.yml`, `Dockerfile` (in server-core)
|
||||||
|
- **Services**:
|
||||||
|
- `postgres`: PostgreSQL 16, volume for data, health check
|
||||||
|
- `redis`: Redis 7, health check
|
||||||
|
- `server-core`: Go binary (multi-stage build), depends on postgres+redis, env vars
|
||||||
|
- **Dockerfile** (server-core): Multi-stage — `golang:1.25-alpine` build stage → `alpine:3.20` runtime
|
||||||
|
- **docker-compose.dev.yml**: Hot-reload via `air` or `nodemon`, exposed ports for local dev
|
||||||
|
- **QA**: `docker-compose up` starts all containers. Server connects to postgres+redis. Health checks pass.
|
||||||
|
|
||||||
|
### Task 3.2: Bash Installer Script ✅
|
||||||
|
- **File**: `scripts/install_agent.sh` (in main repo or device-agent)
|
||||||
|
- **Features**:
|
||||||
|
- Root check
|
||||||

|
||||||
|
- Dependency install: nftables, curl, iproute2, wireguard-tools
|
||||||
|
- Architecture detection: amd64, arm64, armv7l
|
||||||
|
- Binary download from Gitea releases using X-Token-Auth
|
||||||
|
- Binary installation to `/usr/local/bin/` with configurable name (default `sys-bridge`)
|
||||||
|
- Systemd service creation: `/etc/systemd/system/sys-bridge.service`
|
||||||
|
- Service enable + start
|
||||||
|
- **Flags**: `--token`, `--server-url`, `--binary-name`, `--help`
|
||||||
|
- **QA**: Runs on Ubuntu → creates systemd service. Runs on CentOS → uses yum. Missing `--token` prints usage.
|
||||||
|
|
||||||
|
### Task 3.3: Systemd Service Template ✅
|
||||||
|
- **File**: `scripts/sys-bridge.service` (as template), installer generates the actual file
|
||||||
|
- **Service Config**:
|
||||||
|
- Type=simple
|
||||||
|
- ExecStart=/usr/local/bin/sys-bridge

|
||||||
|
- **QA**: `systemctl start sys-bridge` starts the agent. `systemctl status sys-bridge` shows running.
|
||||||
|
|
||||||
|
### Task 3.4: Gitea Actions CI/CD
|
||||||
|
- **File**: `.gitea/workflows/build.yml` (in each repo)
|
||||||
|
- **server-core pipeline**:
|
||||||
|
- `test`: `go test ./... -tags dev -cover`
|
||||||
|
- `build`: `go build -o bin/server-core .`
|
||||||
|
- `docker`: Build and push Docker image to Gitea Container Registry
|
||||||
|
- **device-agent pipeline**:
|
||||||
|
- `test`: `go test ./... -cover`
|
||||||
|
- `cross-build`: Build for linux/amd64, linux/arm64, linux/arm
|
||||||
|
- `release`: Upload binaries to Gitea Releases (tag-based trigger)
|
||||||
|
- **dashboard-ui pipeline**:
|
||||||
|
- `test`: `npm test`
|
||||||
|
- `build`: `npm run build`
|
||||||

|
||||||
|
- **QA**: Push triggers pipeline. Tests pass. Binary releases created.
|
||||||
|
|
||||||
|
### Task 3.5: Environment Configuration
|
||||||
|
- **Files**: `.env.example` in each repo, `scripts/sys-bridge.env.example`
|
||||||
|
- **server-core .env.example**:
|
||||||
|
```env
|
||||||
|
DB_HOST=localhost
|
||||||
|
DB_PORT=5432

|
||||||
|
|
||||||
|
## Phase 4: Dashboard UI (`apps/dashboard-ui`)
|
||||||
|
|
||||||
|
**Goal**: Build the Vue 3 management dashboard — JWT login, device CRUD, firewall rule editor, real-time status monitoring. Web-only (no Android).
|
||||||
|
|
||||||
|
**Phase Dependency**: Phase 1 must be COMPLETE and TAGGED (dashboard consumes Phase 1 API)
|
||||||
|
|
||||||
|
**Entry Criteria**:
|
||||||
|
- [ ] `git tag -l phase-1-server-core` exists in `apps/server-core`
|
||||||
|
- [ ] Server API is running on `http://localhost:8080/api/v1`
|
||||||
|
- [ ] At least one user and device exist in database (for testing dashboard features)
|
||||||
|
- [ ] User has confirmed Phase 3 is done (or Phase 1 if skipping DevOps install)
|
||||||
|
|
||||||
|
**Exit Criteria** (all must pass before Phase 5):
|
||||||
|
- [ ] `npm run dev` starts Vite dev server
|
||||||
|
- [ ] `npm run build` produces production bundle without errors
|
||||||
|
- [ ] Login page: valid credentials → redirect to dashboard. Invalid → error message.
|
||||||
|
- [ ] Device list: shows devices with name, IP, online/offline badge
|
||||||
|
- [ ] Create device: dialog → POST → registration token displayed with copy button
|
||||||
|
- [ ] Device detail: edit name, toggle "Allow Internet", regenerate token
|
||||||
|
- [ ] Delete device: confirmation dialog → device removed from list
|
||||||
|
- [ ] Firewall rule editor: add rule → appears in list. Delete → removed.
|
||||||
|
- [ ] Dashboard: summary cards show correct counts. Polling updates status.
|
||||||
|
- [ ] Error states: loading spinner, error message with retry, empty state
|
||||||
|
- [ ] Responsive layout: sidebar collapses on mobile, works on 375px viewport
|
||||||
|
- [ ] API service adds JWT header to all requests automatically
|
||||||
|
- [ ] 401 response → redirect to /login automatically
|
||||||
|
- [ ] **Gate**: `git tag phase-4-dashboard-ui` pushed to remote
|
||||||
|
- [ ] **Gate**: User confirms "Phase 4 done — proceed to Phase 5"
|
||||||
|
|
||||||
|
### Task 4.1: Vite + Vue 3 Scaffold + API Layer
|
||||||
|
- **Files**: scaffold via `npm create vite@latest`, `src/services/api.ts`, `src/stores/auth.ts`
|
||||||
|
- **Actions**:
|
||||||
|
- Scaffold with Vue 3 + TypeScript + Vite
|
||||||
|
- Add dependencies: vue-router, pinia, axios, tailwindcss, @tailwindcss/vite
|
||||||
|
- Configure Tailwind CSS
|
||||||
|
- Create `src/services/api.ts` — axios instance with base URL from `import.meta.env.VITE_API_BASE_URL`, interceptors for JWT header + 401 redirect
|
||||||
|
- Create `src/stores/auth.ts` — Pinia store for JWT token (localStorage persistence), login/logout actions
|
||||||
|
- Create router with auth guard: redirect to /login if no token
|
||||||
|
- **QA**: `npm run dev` starts. API service adds JWT header. Auth guard works.
|
||||||
|
|
||||||
|
### Task 4.2: Login Page + Auth Flow
|
||||||
|
- **File**: `src/views/Login.vue`, `src/api/auth.ts`
|
||||||
|
- **Components**:
|
||||||
|
- Login form: username + password + submit button
|
||||||
|
- Error display: invalid credentials, server error, network error
|
||||||
|
- Loading state during submission
|
||||||
|
- **API Service**: `src/api/auth.ts` — `login(username, password)`, `register(username, password, adminKey)`
|
||||||
|
- **Flow**: Submit → POST /auth/login → store token in Pinia + localStorage → redirect to /dashboard
|
||||||
|
- **QA**: Login with valid credentials → redirect to dashboard. Invalid → error message. Already logged in → redirect to dashboard automatically.
|
||||||
|
|
||||||
|
### Task 4.3: Device Management Page
|
||||||
|
- **File**: `src/views/Devices.vue`, `src/views/DeviceDetail.vue`, `src/api/devices.ts`, `src/stores/devices.ts`
|
||||||
|
- **Components**:
|
||||||
|
- Device list table: name, IP, status (online/offline badge), last handshake, actions
|
||||||
|
- Create device dialog: name input → POST → show registration token (copy button)
|
||||||
|
- Device detail view: edit name, toggle "Allow Internet", regenerate token
|
||||||
|
- Delete device: confirmation dialog
|
||||||
|
- **API Service**: `src/api/devices.ts` — CRUD calls
|
||||||
|
- **Store**: `src/stores/devices.ts` — Pinia store with device list, selected device, polling interval
|
||||||
|
- **QA**: Create device → appears in list with token. Delete → removed from list. Status badge reflects online/offline.
|
||||||
|
|
||||||
|
### Task 4.4: Firewall Rule Editor
|
||||||
|
- **File**: `src/views/FirewallRules.vue` (or tab in DeviceDetail), `src/api/rules.ts`
|
||||||
|
- **Components**:
|
||||||
|
- Rules list for selected device: table of dest_ip, dest_port, protocol, action, delete button
|
||||||
|
- Add rule form: dest IP (single/CIDR/range), dest port (single/range), protocol (TCP/UDP/Both), action (Accept/Drop)
|
||||||
|
- "Allow Internet" toggle switch (separate from specific rules)
|
||||||
|
- **Validation**:
|
||||||
|
- IP format validation (single, CIDR, range: 192.168.1.10-192.168.1.20)
|
||||||
|
- Port validation (single: 80, range: 8000-9000)
|
||||||
|
- No duplicate rule submission
|
||||||
|
- **QA**: Add rule → appears in list. Delete rule → removed. Allow Internet toggle → updates device. Invalid IP → validation error.
|
||||||
|
|
||||||
|
### Task 4.5: Dashboard + Status Monitoring
|
||||||
|
- **File**: `src/views/Dashboard.vue`, `src/stores/dashboard.ts`
|
||||||
|
- **Components**:
|
||||||
|
- Summary cards: total devices, online count, offline count, active rules count
|
||||||
|
- Device status grid: cards with name, IP, online/offline indicator, last handshake time
|
||||||
|
- Auto-refresh: polling every 10s (NOT WebSocket)
|
||||||
|
- Visual indicators: green dot = online (< 90s since ping), red dot = offline, gray = unknown
|
||||||
|
- **Store**: `src/stores/dashboard.ts` — polling timer, device status cache
|
||||||
|
- **QA**: Dashboard shows correct counts. Online/offline indicators update with polling. Summary cards reflect data.
|
||||||
|
|
||||||
|
### Task 4.6: Navigation Shell + Responsive Layout
|
||||||
|
- **File**: `src/App.vue`, `src/components/Sidebar.vue`, `src/components/Navbar.vue`, `src/router/index.ts`
|
||||||
|
- **Components**:
|
||||||
|
- Sidebar: logo, nav links (Dashboard, Devices), user info + logout
|
||||||
|
- Top navbar: breadcrumb, mobile hamburger menu
|
||||||
|
- Responsive: sidebar collapses on mobile, full sidebar on desktop
|
||||||
|
- **Routes**:
|
||||||
|
- `/login` — Login page (public)
|
||||||
|
- `/dashboard` — Dashboard (protected)
|
||||||
|
- `/devices` — Device list (protected)
|
||||||
|
- `/devices/:id` — Device detail + firewall rules (protected)
|
||||||
|
- **QA**: All routes work. Auth guard redirects to /login. Responsive layout works on mobile viewport.
|
||||||
|
|
||||||
|
### Task 4.7: Error Handling + UX Polish
|
||||||
|
- **Files**: `src/components/ErrorBoundary.vue`, `src/components/LoadingSpinner.vue`, `src/components/EmptyState.vue`
|
||||||
|
- **Components**:
|
||||||
|
- Error boundary for API failures: retry button, error message
|
||||||
|
- Loading spinner for async operations
|
||||||
|
- Empty state: "No devices yet. Create your first device."
|
||||||
|
- Toast notification component for success/error feedback (create, delete, update)
|
||||||
|
- Confirmation dialog for destructive actions (delete device, regenerate token)
|
||||||
|
- **QA**: API failure shows error with retry. Loading spinner shows during requests. Toast appears after CRUD actions.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## Phase 5: Advanced Features (Deferred)
|
||||||
|
|
||||||
|
**Goal**: Document the deferred features. No implementation — only architectural notes for future phases.
|
||||||
|
|
||||||
|
**Phase Dependency**: All prior phases COMPLETE and TAGGED
|
||||||
|
|
||||||
|
**Entry Criteria**:
|
||||||
|
- [ ] `git tag -l phase-1-server-core` exists
|
||||||
|
- [ ] `git tag -l phase-2-device-agent` exists
|
||||||
|
- [ ] `git tag -l phase-3-devops` exists
|
||||||
|
- [ ] `git tag -l phase-4-dashboard-ui` exists
|
||||||
|
- [ ] User has confirmed Phase 4 is done
|
||||||
|
|
||||||
|
**Exit Criteria**:
|
||||||
|
- [ ] `docs/TLS_DEPLOYMENT.md` contains nginx + Caddy reverse proxy configs with Let's Encrypt
|
||||||
|
- [ ] STUN signaling architectural notes documented in `docs/STUN_ARCHITECTURE.md`
|
||||||
|
- [ ] Key rotation plan documented in `docs/KEY_ROTATION.md`
|
||||||
|
- [ ] Peer discovery design documented in `docs/PEER_DISCOVERY.md`
|
||||||
|
- [ ] **Gate**: User confirms "All phases complete. System ready."
|
||||||
|
|
||||||
|
### Task 5.1: nginx/Caddy TLS Documentation
|
||||||
|
- **File**: `docs/TLS_DEPLOYMENT.md` (in server-core)
|
||||||
|
- **Content**: nginx and Caddy reverse proxy config templates for TLS termination, Let's Encrypt auto-provisioning, HTTP-to-HTTPS redirect
|
||||||
|
- **Note**: Documentation only. No code changes.
|
||||||
|
|
||||||
|
### Task 5.2: STUN Signaling Notes
|
||||||
|
- **Document**: Architectural notes for UDP hole punching
|
||||||
|
- **Server**: STUN endpoint on server-core, `/api/v1/stun` — returns public IP:port of the agent
|
||||||
|
- **Agent**: On start, send STUN request to server. Server records public endpoint. Agent receives peer's public endpoint via polling/push.
|
||||||
|
- **Implementation**: Deferred to future phase.
|
||||||
|
|
||||||
|
### Task 5.3: Key Rotation Notes
|
||||||
|
- **Document**: 30-day key rotation plan
|
||||||
|
- **Dual-key buffer**: Server generates new keypair 5 minutes before expiry. Agent fetches new key while old key is active. Graceful handover period.
|
||||||
|
- **Implementation**: Deferred to future phase.
|
||||||
|
|
||||||
|
### Task 5.4: Peer Discovery Notes
|
||||||
|
- **Document**: `/api/v1/peers` endpoint spec
|
||||||
|
- **Design**: Server maintains device list with internal IP per user. When new device provisions, server pushes/notifies all peers in same user group.
|
||||||
|
- **Implementation**: Deferred to future phase.
|
||||||

## Roll-up Verification Wave (End-to-End)
|
||||||
|
|
||||||
|
**Run this ONLY after all 5 phases are complete and tagged.** This validates the integrated system works end-to-end. Each individual check here should already have passed during per-phase exit gates — this is a final integration smoke test.
|
||||||
|
|
||||||
|
### Pre-flight: Phase Tags Check
|
||||||
|
- [ ] `git tag -l` in `apps/server-core` shows `phase-1-server-core`
|
||||||
|
- [ ] `git tag -l` in `apps/device-agent` shows `phase-2-device-agent`
|
||||||
|
- [ ] `git tag -l` in root shows `phase-3-devops`
|
||||||
|
- [ ] `git tag -l` in `apps/dashboard-ui` shows `phase-4-dashboard-ui`
|
||||||
|
- [ ] All docs exist from Phase 5
|
||||||
|

### Integration Smoke Tests
|
||||||
|
| # | Test | Expected | If Fails |
|
||||||
|
|---|------|----------|----------|
|
||||||
|
| 1 | `docker-compose up` → PostgreSQL + Redis + Server-Core start | All 3 containers healthy | Fix Phase 3 |
|
||||||
|
| 2 | `POST /api/v1/auth/register` (admin) | 201 + JWT token | Fix Phase 1 |
|
||||||
|
| 3 | `POST /api/v1/auth/login` | 200 + JWT token | Fix Phase 1 |
|
||||||
|
| 4 | `POST /api/v1/devices` (with JWT) | 201 + device + reg token | Fix Phase 1 |
|
||||||
|
| 5 | Agent binary runs: `./sys-bridge --server-url http://localhost:8080 --token REG-TOKEN` | Tunnel established, no errors | Fix Phase 2 |
|
||||||
|
| 6 | `GET /api/v1/devices` → device shows "online" | Status = online | Fix Phase 1/2 |
|
||||||
|
| 7 | Dashboard login → device list shows device | Device visible in UI | Fix Phase 4 |
|
||||||
|
| 8 | Dashboard: create firewall rule → SSH verify nftables | Rule appears in `nft list table` | Fix Phase 1/4 |
|
||||||
|
| 9 | Toggle "Allow Internet" in dashboard → verify nftables | Verdict map changes | Fix Phase 1/4 |
|
||||||
|
| 10 | Delete device in dashboard → verify nftables cleanup | Set element removed | Fix Phase 1/4 |
|
||||||
|
| 11 | Kill agent process → server marks offline within 90s | Status = offline | Fix Phase 1/2 |
|
||||||
|
| 12 | Restart agent → reconnects automatically | Status returns to online | Fix Phase 2 |
|
||||||
|
| 13 | Bash installer on fresh Ubuntu VM | Installs deps + binary + systemd | Fix Phase 3 |
|
||||||
|
| 14 | Gitea Actions: push to any repo → pipeline triggers | Green build | Fix Phase 3 |
|
||||||
|
|
||||||
|
### Pass / Fail Decision
|
||||||
|
- **ALL 14 pass**: System is complete and production-ready. 🟢
|
||||||
|
- **Any fail**: Fix the failing component in its original phase. Do NOT create workarounds in other phases.
|
||||||
|
|
||||||
|
**Approval required from user. Run each check, report results.**
