Kuzz007 9408424959 fix(panel): forward the panel's proxy to update.sh's own downloads (#6259)
* fix(panel): route update.sh's own downloads through the resolved proxy

startUpdate already fetches update.sh itself via a proxy-aware HTTP
client (NewProxiedHTTPClient), but the process that actually runs it
never got a proxy hint of its own -- so update.sh's own curl calls to
GitHub always went direct, even when the panel has a working proxy
path configured. This matters most for the systemd-run launch path,
which doesn't inherit the caller's environment at all (only --setenv
passes through), so a systemd host with a real ambient proxy would
silently lose it for this one hop.

curl already honors https_proxy/all_proxy natively, so no changes to
update.sh itself are needed -- only the launcher needs to forward a
proxy URL into the environment it hands to that detached process.

updateProxyEnvVars() prefers an already-set ambient proxy env var
(never silently overriding an admin's own proxy config) and only
falls back to the panel's own configured panel outbound
(PanelEgressProxyURL) when nothing is set, then forwards the result
to both launch paths.

* test(panel): cover updateProxyEnvVars' ambient-proxy path

Regression test for the fix in the previous commit -- an ambient
https_proxy must reach update.sh's own downloads, not just the
panel's own outbound requests. Scoped to the ambient-env branch only,
which never touches PanelEgressProxyURL/the database.

* fix: drop the panel-outbound fallback in updateProxyEnvVars

Per review: PanelEgressProxyURL() returns a loopback SOCKS bridge
living inside the panel's own Xray child. update.sh stops that child
partway through its run (systemctl stop x-ui, no KillMode override --
the default cgroup kill takes Xray with it) and removes the service
unit, but still needs curl afterwards for x-ui.sh and sometimes the
service unit itself. With the bridge dead, those downloads fail and
update.sh exits with no service unit installed and nothing to restart
it -- a host with a panel outbound configured and no ambient proxy
would be bricked by its next update.

Keep only the ambient-env-var forwarding, which is safe (an OS-level
var, not torn down when the panel dies), and fold in three smaller
fixes: forward no_proxy/NO_PROXY too, since install_base's apt/dnf
calls honor them; stop promoting a deliberately HTTP-only http_proxy
into https_proxy/all_proxy; and drop the now-redundant re-append on
the bash fallback path, which already inherits everything via
os.Environ().

3x-ui

Release Build GO Version Downloads License Go Reference

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)

To install a specific version, append its tag (e.g. v3.4.0):

bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh) v3.4.0

To install the rolling dev build (latest per-commit pre-release from main, not a stable release), pass dev-latest:

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

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

The installer also runs non-interactively for cloud-init. 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

XUI_TUNNEL_HEALTH_PROXY Proxy the probe is sent through; point it at a local xray inbound so the probe tests the tunnel (e.g. socks5://127.0.0.1:1080). Empty means the probe only checks host connectivity
