Rouzbeh† dab0add191 feat(finalmask): support Salamander packetSize (Gecko) and Realm tlsConfig for Hysteria2 (#5278)
* feat(finalmask): support salamander packetSize (Gecko) and realm tlsConfig

Hysteria v2.9.1/v2.9.2 added two finalmask features that the pinned
Xray-core (26.6.1, 94ffd50) already supports but the panel UI did not
expose: Salamander's packetSize range (Gecko, XTLS/Xray-core#6198) and
the Realm UDP hole-punching mask's optional tlsConfig (XTLS/Xray-core#6137).

Add typed schemas and form fields for both, keeping UdpMaskSchema.settings
permissive per the existing finalmask design note. packetSize reuses the
existing dash-range preprocess (like udpHop.ports) so it round-trips under
the fm= share-link param with no new URI key; realm tlsConfig emits xray's
flat TLSConfig shape (serverName/alpn/fingerprint/allowInsecure).

Verified against the bundled Xray 26.6.1: configs with packetSize and
realm tlsConfig validate (Configuration OK.), plain salamander stays
backward-compatible, and a malformed packetSize is correctly rejected by
the salamander mask builder.

* test(finalmask): add snapshots for salamander-gecko and realm-tls fixtures

vitest run does not auto-create missing snapshots in CI mode, so the two
new fixtures need committed snapshot entries. Verified under node:22 that
finalmask.test.ts passes (6/6) with these snapshots.

* feat(finalmask): polished Gecko UX with core-grounded validation

Fold PR #5281's Gecko work into the Realm tlsConfig base:

- Replace the plain packetSize input with a Salamander/Gecko mode
  selector and validated Min/Max number inputs.
- parseGeckoPacketSize enforces xray-core's real bound
  (1 <= min <= max <= 2048, the gecko buffer size) so the panel
  rejects configs core would reject at runtime.
- Accurate Gecko description; add parser unit tests.
- Drop the unused Salamander/Realm settings schemas; settings stay
  permissive and are validated at the form level.

3x-ui

Release Build GO Version Downloads License Go Reference Go Report Card

3X-UI is an advanced, open-source web control panel for managing Xray-core servers. It provides a clean, multi-language interface for deploying, configuring, and monitoring a wide range of proxy and VPN protocols — from a single VPS to multi-node deployments.

Built as an enhanced fork of the original X-UI project, 3X-UI adds broader protocol support, improved stability, per-client traffic accounting, and many quality-of-life features.

Important

This project is intended for personal use only. Please do not use it for illegal purposes or in a production environment.

Features

  • Multi-protocol inbounds — VLESS, VMess, Trojan, Shadowsocks, WireGuard, Hysteria2, HTTP, SOCKS (Mixed), Dokodemo-door / Tunnel, and TUN.
  • Modern transports & security — TCP (Raw), mKCP, WebSocket, gRPC, HTTPUpgrade, and XHTTP, secured with TLS, XTLS, and REALITY.
  • Fallbacks — serve multiple protocols on a single port (e.g. VLESS and Trojan on 443) using Xray's fallback support.
  • Per-client management — traffic quotas, expiry dates, IP limits, live online status, and one-click share links, QR codes, and subscriptions.
  • Traffic statistics — per inbound, per client, and per outbound, with reset controls.
  • Multi-node support — manage and scale across multiple servers from a single panel.
  • Outbound & routing — WARP, NordVPN, custom routing rules, load balancers, and outbound proxy chaining.
  • Built-in subscription server with multiple output formats and custom page templates.
  • Telegram bot for remote monitoring and management.
  • RESTful API with in-panel Swagger documentation.
  • Flexible storage — SQLite (default) or PostgreSQL.
  • 13 UI languages with dark and light themes.
  • Fail2ban integration for enforcing per-client IP limits.

Quick Start

bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh)

During installation a random username, password, and access path are generated. After installation, run x-ui to open the management menu, where you can start/stop the service, view or reset your login credentials, manage SSL certificates, and more.

For full documentation, please visit the project Wiki.

Unattended install & cloud images

The installer also runs non-interactively for cloud-init and golden images. Set XUI_NONINTERACTIVE=1 (or pipe with no TTY) and it installs end-to-end with zero prompts, generating random credentials and writing them to /etc/x-ui/install-result.env. See deploy/ for:

Supported Platforms

Operating systems: Ubuntu, Debian, Armbian, Fedora, CentOS, RHEL, AlmaLinux, Rocky Linux, Oracle Linux, Amazon Linux, Virtuozzo, Arch, Manjaro, Parch, openSUSE (Tumbleweed / Leap), Alpine, and Windows.

Architectures: amd64 · 386 · arm64 (aarch64) · armv7 · armv6 · armv5 · s390x.

Database Options

3X-UI supports two backends, chosen during the install:

  • SQLite (default) — a single file at /etc/x-ui/x-ui.db. Zero setup, ideal for small and medium deployments.
  • PostgreSQL — recommended for high client counts or multi-node setups. The installer can install PostgreSQL locally for you, or accept a DSN to an existing server.

At runtime the backend is selected via environment variables (the installer writes these to /etc/default/x-ui for you):

XUI_DB_TYPE=postgres
XUI_DB_DSN=postgres://xui:password@127.0.0.1:5432/xui?sslmode=disable

Migrating an existing SQLite install to PostgreSQL

x-ui migrate-db --dsn "postgres://xui:password@127.0.0.1:5432/xui?sslmode=disable"
# then set XUI_DB_TYPE and XUI_DB_DSN in /etc/default/x-ui and restart:
systemctl restart x-ui

The source SQLite file is left untouched; remove it manually once you have verified the new backend.

Docker

The default docker compose up -d keeps using SQLite. To run with the bundled PostgreSQL service, uncomment the two XUI_DB_* env lines in docker-compose.yml and start with the profile:

docker compose --profile postgres up -d

The image bundles Fail2ban (enabled by default) to enforce per-client IP limits. Fail2ban bans offenders with iptables, which requires the NET_ADMIN capability. docker-compose.yml already grants it via cap_add; if you start the container with docker run instead, add the capabilities yourself, otherwise bans are logged but never applied:

docker run -d --cap-add=NET_ADMIN --cap-add=NET_RAW ... ghcr.io/mhsanaei/3x-ui

Environment Variables

Variable Description Default
XUI_DB_TYPE Database backend: sqlite or postgres sqlite
XUI_DB_DSN PostgreSQL connection string (when XUI_DB_TYPE=postgres)
XUI_DB_FOLDER Directory for the SQLite database file /etc/x-ui
XUI_DB_MAX_OPEN_CONNS Maximum open connections (PostgreSQL pool)
XUI_DB_MAX_IDLE_CONNS Maximum idle connections (PostgreSQL pool)
XUI_INIT_WEB_BASE_PATH The initial URI path for the web panel /
XUI_ENABLE_FAIL2BAN Enable Fail2ban-based IP-limit enforcement true
XUI_LOG_LEVEL Log verbosity (debug, info, warning, error) info
XUI_DEBUG Enable debug mode false

Supported Languages

The panel UI is available in 13 languages:

English · فارسی · العربية · 中文(简体) · 中文(繁體) · Español · Русский · Українська · Türkçe · Tiếng Việt · 日本語 · Bahasa Indonesia · Português (Brasil)
