Howdy is a biometric authentication system for Linux that uses infrared cameras to provide passwordless login and privileged access. It functions as a Pluggable Authentication Module to integrate facial recognition into the standard Linux authentication pipeline. The system relies on near-infrared camera feeds and facial models to verify identity, ignoring visible light interference. Biometric data is stored as encrypted mathematical templates on the local disk to ensure that facial models are not transmitted over a network. The project includes tools for face model management, infrared came

ejabberd is a multi-protocol communication gateway and scalable server that implements XMPP for instant messaging and presence. It serves as a federated messaging platform, enabling interoperable communication and user discovery between different remote servers. The project functions as an MQTT message broker for lightweight IoT device communication and a SIP signaling server for managing voice and multimedia signaling traffic. It allows for the hosting of multiple domains on a single instance using virtual hosting to isolate configurations and prevent username conflicts. The system provides

Maddy is a modular mail server that assembles a complete email system by connecting small, single-purpose modules through a declarative configuration file. Rather than a monolithic stack, it lets operators compose message processing, storage, authentication, and security enforcement from interchangeable building blocks, with each module handling a specific function like receiving SMTP connections, verifying credentials, or applying policy checks. The server distinguishes itself through its flexible authentication and security architecture. It delegates user verification to external systems in

AliSQL is a fork of MySQL by Alibaba that extends the relational database management system with enhancements for high performance, scalability, and enterprise-grade availability. It retains the core MySQL identity as a SQL-based database for storing, organizing, and retrieving structured data, while adding optimizations for large-scale transactional and analytical workloads. The project differentiates itself through a set of Alibaba-specific improvements, including a columnar engine for accelerating analytical queries directly on MySQL tables, and a distributed, shared-nothing NDB Cluster en

PgBouncer is a lightweight middleware proxy server and connection pooler for PostgreSQL. It acts as a database connection manager and load balancer, reducing system overhead by managing a pool of reusable connections and distributing incoming traffic across multiple backend servers. The project distinguishes itself through a protocol-level proxying approach that handles authentication and TLS encryption without parsing underlying SQL queries. It provides specialized support for mapping named prepared statements across different backend connections and implements a socket-sharing process model

هذا المشروع عبارة عن وحدة مصادقة قابلة للتوصيل (PAM) لأنظمة Linux تفرض التحقق من الهوية متعدد العوامل. يتكامل مباشرة في مكدس مصادقة النظام لطلب كلمات مرور لمرة واحدة قائمة على الوقت إلى جانب بيانات اعتماد المستخدم القياسية، مما يوفر آلية لتأمين الوصول إلى الصدفة (shell) المحلية والبعيدة. تتميز الوحدة بتنفيذها لخوارزمية كلمة المرور لمرة واحدة القائمة على الوقت، والتي تتضمن دعماً مدمجاً لتعويض انحراف الساعة لمراعاة تباينات الوقت بين الخوادم وأجهزة المستخدم. وتدير مفاتيح سرية لكل مستخدم من خلال آلية استمرار قائمة على الملفات المحلية وتدعم التكديس النمطي، مما يسمح للمسؤولين بتمرير بيانات الاعتماد بين وحدات مصادقة متعددة ضمن تدفق تسجيل دخول واحد. بعيداً عن التحقق الأساسي، توفر الأداة إعدادات سياسة قابلة للتهيئة تسمح للمسؤولين بتحديد فترات السماح وإدارة مواقع الملفات السرية. وتسهل مزامنة أسرار المصادقة الفريدة مع تطبيقات الهاتف المحمول، مما يضمن بقاء الإنفاذ متعدد العوامل فعالاً مع الحفاظ على معايير أمن النظام.
