1. Executive Summary

nx9-wg is a sovereign, self-hosted, Linux-native VPN and network control plane built directly around the Linux kernel's in-tree WireGuard implementation (wireguard.ko).

Rather than functioning as a fragile user interface wrapper that shells out to external command-line utilities (wg, ip, nft, sysctl), nx9-wg establishes an integrated, single-binary architecture. It combines authoritative SQLite desired-state persistence, direct kernel Netlink execution (RTNETLINK and WireGuard Generic Netlink), in-process Netfilter firewall/NAT compilation (libnftables.so.1), continuous closed-loop reconciliation, a multi-format native CLI, and an embedded zero-dependency Single Page Application (SPA) Web UI.


2. The NX9 Philosophy in Implementation

Every design and architectural choice in nx9-wg directly reflects the core philosophy of the NX9 Ecosystem (https://nx9.in):

NX9 Principle Core Intent nx9-wg Implementation
🔑 Operator Ownership Full control over binaries, configurations, databases, keys, and backups with zero dependency on cloud-hosted control planes. 100% local operation. Private keys, configuration data, and encryption parameters never leave the operator's host.
🖥️ Self-Hosting First Built to be deployed and operated effortlessly by a single administrator without requiring Kubernetes or external infrastructure. Self-contained single executable. Bootstrapped with a single command (nx9-wg init), running seamlessly under standard systemd.
⚡ Simplicity Over Complexity One binary, one configuration file, one SQLite database, one administrator. No multi-daemon orchestration, no external message queues, no Node.js runtime, no Python scripts, and zero shell wrappers.
🛡️ Privacy by Default Zero analytics, zero telemetry collection, zero third-party tracking, and zero assumptions of external cloud connectivity. No phone-home telemetry. Completely air-gapped capable with all static assets, fonts, and scripts embedded in the binary.
🔒 Security by Design Modern cryptography, strict invariants, and append-only audit logging embedded from day one. Argon2id password hashing, SHA-256 token digests, X25519 key generation, single-admin database constraint (CHECK (id=1)), and strict secret redaction.
🔧 Operational Excellence Diagnostics, backup/restore, migration tools, CLI management, and comprehensive documentation built-in. Multi-subsystem automated health inspections, atomic online SQLite VACUUM INTO snapshots with SHA-256 manifests, and 100% CLI parity.
⏳ Long-Term Stability Avoid dependency churn. Build software that remains understandable and maintainable years into the future. Built in stable native Rust (Edition 2024), standard SQLite 3 storage, standard TOML configuration, and POSIX-compliant systemd integration.
🌐 Open Source First 100% free and open-source software under permissive licensing. Dual-licensed under MIT OR Apache-2.0. Complete freedom to inspect, audit, build, and extend.
♾️ Zero Vendor Lock-In Standard data formats, open protocols, and zero proprietary cloud lock-in. Standard SQLite database, standard WireGuard .conf files, standard RFC-compliant JSON/YAML/CSV output formats, and open Netlink sockets.

Disadvantages: Fragile process spawning, race conditions, lack of atomic state, broken host routing, vulnerability to configuration drift, and heavy runtime dependency footprints.

The Six Reconciliation Lifecycle States

  1. Plan: Read-only calculation of drift between SQLite and kernel.
  2. Applying: In-progress dispatch of native mutations across execution planes.
  3. Verifying: Querying live kernel state to confirm applied changes took effect.
  4. Converged: 100% synchronization achieved with zero remaining drift.
  5. PartialFailure: One or more execution planes failed during apply (e.g. permission error).
  6. DriftRemains: Apply completed without fatal error, but post-verification detected unapplied state.

8. Embedded Single Page Application (SPA) & WebSockets

The nx9-wg frontend is a zero-dependency HTML5/CSS/JavaScript SPA embedded directly into the Rust binary:

  • Zero External Toolchains: No Node.js, npm, Webpack, Vite, React, or external CDN dependencies.
  • Embedded In-Memory Delivery: Bundled at compile-time via include_str!() and served from memory.
  • Design Tokens: Custom CSS token system (crates/nx9-wg-ui/src/css.rs) supporting Light and Dark modes.
  • Real-Time WebSocket Stream: Subscribes to ws://<host>/api/v1/ws for live handshakes and drift alerts without polling.
  • 15 Interactive Views:
    1. #dashboard — System overview, uptime, interface/peer counts, health cards.
    2. #interfaces — WireGuard interface CRUD, listen port, MTU, state toggles.
    3. #peers — Enrolled peer table, real-time handshakes, profile resolution, .conf export, SVG QR modal.
    4. #networks — Subnet network ranges, CIDR masks, available IP inspector.
    5. #routes — Kernel route definitions, gateway assignments, interface scoping.
    6. #firewall — nftables packet filtering rules in table inet nx9_wg, priority sorting.
    7. #nat — Managed subnet NAT masquerade status and instant toggle.
    8. #forwarding — Kernel IPv4/IPv6 packet forwarding status and toggle.
    9. #reconciliation — Real-time kernel drift overview, action plan table, interactive Apply button.
    10. #diagnostics — Automated multi-subsystem health checks with remediation hints.
    11. #live-state — Raw Linux Netlink telemetry, active kernel interfaces, live routing table.
    12. #settings — Key-value appliance parameters and danger zone reset controls.
    13. #backups — Online SQLite backup snapshots list, instant backup creation, .db download.
    14. #audit — Append-only security and administrative audit trail.
    15. #administrator — Admin account verification, password rotation, and one-time API token generation.

11. Security Model & Capability Isolation

A. Single Administrator Identity

  • Database-level integrity constraint: CHECK (id = 1) in admins table.
  • Eliminates multi-tenant privilege escalation and role-confusion attack surfaces.

B. Credential Protection

  • Passwords: Hashed with Argon2id using unique cryptographic salts.
  • API Tokens: Stored exclusively as SHA-256 digests in SQLite; raw tokens are displayed once upon creation.
  • Secret Redaction: Private keys, preshared keys, and password hashes implement custom std::fmt::Debug implementations returning [REDACTED].

C. Hardened systemd Sandbox (nx9-wg.service)

12. Disaster Recovery, Backups & Upgrades

Atomic Online Backups

  • Uses SQLite VACUUM INTO to produce non-blocking, consistent binary database snapshots while the daemon is actively serving traffic.
  • Generates SHA-256 manifest records for each snapshot.
