[MD] # VelocityMultiAccountLimit **A lightweight Velocity proxy plugin that prevents multiple accounts from connecting from the same IP address + anti-bot detection.** --- ## Features - 🛡️ **Per-IP Connection Limit** — Set a maximum number of concurrent connections per IP address - 🤖 **Anti-Bot Detection** — Three-layer bot detection: username pattern analysis, rapid reconnection detection, and banned-IP reconnection blocking - **Bilingual Support** — Built-in Chinese (zh_CN) and English (en_US) language files - **Colored Console Logs** — Real-time colored console output (green for allowed, red for blocked/bot) - **Hot Reload** — Reload config and language without restarting the proxy (`/vmultireload`) - **Thread-Safe** — Concurrent connection tracking with synchronized IP counting - **Customizable Kick Message** — Supports color codes and multi-line messages - **Editable Language Files** — YAML-based language files in the plugin's `lang/` directory ## How It Works When a player connects to the proxy, the plugin runs two stages of checks: **Stage 1 — Anti-Bot Detection** (v1.1.0+): - Analyzes username patterns (vowel density, case transitions, consonant runs) to detect randomly-generated script bot names - Tracks rapid reconnection attempts from the same IP - Blocks banned IPs from reconnecting with new accounts **Stage 2 — IP Connection Limit**: - **Below limit** → Player is allowed in, connection count increases - **At or above limit** → Player is kicked with a configurable message, connection is logged in red - **Player disconnects** → Connection count decreases automatically The plugin operates at the `LoginEvent` stage — after authentication but before the player joins a server. ## Commands | Command | Permission | Description | |---------|-----------|-------------| | `/vmultireload` | `velocitymultilimit.reload` | Hot-reload config and language files | Alias: `/vmlreload` ## Permissions | Node | Default | Description | |------|---------|-------------| | `velocitymultilimit.reload` | OP / Console | Allows using the reload command | ## Installation 1. Place the JAR in your Velocity proxy's `plugins/` folder 2. Restart the proxy (or use `/velocity plugin load` if supported) 3. A default `config.properties` will be created in `plugins/VelocityMultiAccountLimit/` 4. Language files (`zh_cn.yml`, `en_us.yml`) will be created in `plugins/VelocityMultiAccountLimit/lang/` ## Configuration ### `config.properties` | Option | Default | Description | |--------|---------|-------------| | `language` | `zh_CN` | Language setting (`zh_CN` or `en_US`) | | `max-connections-per-ip` | `3` | Max connections per IP (`-1` = unlimited) | | `kick-message` | *(empty)* | Custom kick message (uses language default if empty). Supports `&` color codes and `\n` for new lines. | | `anti-bot.enabled` | `true` | Enable anti-bot detection | | `anti-bot.name-pattern.enabled` | `true` | Enable username pattern analysis (separate toggle; disable if false-positives occur) | | `anti-bot.score-threshold` | `0.55` | Username pattern score threshold (0.0~1.0, recommended 0.50~0.65) | | `anti-bot.rapid-connect.enabled` | `true` | Enable rapid reconnection detection | | `anti-bot.rapid-connect.max-attempts` | `5` | Max connection attempts within the time window | | `anti-bot.rapid-connect.window-minutes` | `10` | Time window in minutes for rapid connect detection | | `anti-bot.kick-message` | *(empty)* | Custom kick message for bot detection (uses language default if empty) | ### Example ```properties language=en_US max-connections-per-ip=2 kick-message=&cYou already have an account on this server!\n&eLimit: &6%d anti-bot.name-pattern.enabled=true anti-bot.score-threshold=0.55 anti-bot.rapid-connect.max-attempts=5 ``` ## Language Files Language files are stored in `plugins/VelocityMultiAccountLimit/lang/` as YAML files. You can edit them directly to customize any message. The plugin will copy default files from the JAR if they don't exist. **Available languages:** - `zh_cn.yml` — Chinese (Simplified) - `en_us.yml` — English (US) ## Console Output Example ``` [VelocityMultiLimit] Allowed: Steve (IP: 192.168.1.100) - Current IP online: 1 [VelocityMultiLimit] Blocked: Alex (IP: 192.168.1.100) └─ Exceeded alt-account limit (Blocked: 1/1) [VelocityMultiLimit] Bot blocked: DxZZfVyhAtBQ (IP: 14.150.218.209) └─ Suspicious username pattern (score: 0.79/0.55) [VelocityMultiLimit] Player disconnected: Steve (IP: 192.168.1.100) ``` ## Requirements - **Velocity** 3.0.0 or higher (4.0.0 supported) - **Java** 21 or higher ## Changelog ### v1.2.0 — Anti-Bot Detection - **New**: Three-layer anti-bot detection system - Username pattern analysis (vowel ratio, case transitions, consonant runs) - Rapid reconnection detection (same IP, many accounts, short time window) - Banned-IP reconnection blocking - **New**: Each detection layer has its own enable/disable toggle - `anti-bot.name-pattern.enabled` — toggle username pattern analysis independently - `anti-bot.rapid-connect.enabled` — toggle rapid reconnection detection independently - **New**: Configurable detection threshold and time windows - `anti-bot.score-threshold` — sensitivity (0.0~1.0) - `anti-bot.rapid-connect.max-attempts` — max attempts per window - `anti-bot.rapid-connect.window-minutes` — time window - **New**: Bot detection stats tracking - **New**: `anti-bot.*` configuration options in `config.properties` - **New**: Bilingual anti-bot messages in language files - **Update**: `/vmultireload` now re-initializes bot detector with new config - **Update**: Enhanced console logging with bot detection reasons ### v1.1.0 — *(Skipped, internal version alignment)* ### v1.0.0 — Initial Release - Per-IP connection limit - Bilingual support (zh_CN / en_US) - Hot reload capability - Customizable kick messages - Colored console output ### v1.0.0 — Initial Release - Per-IP connection limit - Bilingual support (zh_CN / en_US) - Hot reload capability - Customizable kick messages - Colored console output ## Support - Issues: [GitHub Issues](https://github.com/LiquidTeam/VelocityMultiAccountLimit/issues) - Source: [GitHub](https://github.com/LiquidTeam/VelocityMultiAccountLimit) [/MD]
