NETworkManager is a comprehensive Windows-based network administration and troubleshooting tool built with WPF and the MVVM pattern. It provides an integrated suite of network utilities including remote access (RDP, PowerShell, PuTTY, TigerVNC, WebConsole), network diagnostics (WiFi scanner, IP/port scanners, ping monitor, traceroute, DNS lookup), configuration tools (firewall, hosts file editor), and various network utilities (subnet calculator, bit calculator, OUI/port lookup, RDAP/Whois, IP geolocation). The application features a tabbed interface where each tool operates as a separate tab, profile-based configuration management for saving host/group settings, settings persistence with system-wide policy support, localization for 16+ languages, and data export capabilities (CSV, XML, JSON). The architecture follows clean separation of concerns with dedicated projects for Controls, Converters, Models, Profiles, Settings, Utilities, and ViewModels/View pairs.
RustDesk is a full-featured, open-source remote desktop application written primarily in Rust with a Flutter frontend. In production, it enables remote control, file transfer, clipboard synchronization, audio/video streaming, TCP tunneling, printer sharing, and camera streaming across Windows, macOS, Linux, Android, and iOS. The architecture is a client-server model with a rendezvous/relay server for NAT traversal, a plugin system for extensibility, and platform-specific backends for screen capture (DXGI, X11, Wayland, Quartz, Android MediaProjection), input simulation (enigo), and clipboard file transfer (RDP-based protocol with FUSE on Unix). Key entry points include `src/main.rs` (CLI), `src/server.rs` (host service), `src/client.rs` (remote session), and the Flutter UI in `flutter/`. Data flows involve encrypted peer-to-peer connections (NaCl), adaptive video codec selection (VP8/VP9/AV1/H264/H265 with hardware acceleration), and IPC via named pipes with OS-level authentication. External dependencies include libvpx, libyuv, FFmpeg, Opus, and platform-specific SDKs (Windows IddCx, macOS CoreGraphics, Linux Wayland/D-Bus). The codebase is actively maintained with frequent commits, CI/CD pipelines, and a large community (120k+ stars).
Aspia is a comprehensive, cross-platform remote desktop and system administration suite. The codebase is decomposed into four primary components: a **host** (the machine being controlled), a **client** (the controlling machine), a **router** (session brokering and NAT traversal), and a **relay** (traffic forwarding). It supports Windows, Linux, macOS, and Android, with platform-specific implementations for screen capture (DXGI, X11, Wayland/PipeWire, KMS/DRM, Android MediaProjection), audio (WASAPI, PulseAudio, Oboe), input injection, and clipboard integration. The system uses encrypted communication with SRP authentication, X25519 key exchange, and AEAD ciphers (AES-256-GCM, ChaCha20-Poly1305) with key ratcheting. Beyond desktop sharing, it provides file transfer, text chat, remote terminal, task manager, system information collection, and video recording. The client features both a Qt-based desktop GUI and a custom Android UI built with native widgets. The router manages host discovery, two-factor authentication (TOTP), and relay session keys, while the relay handles peer-to-peer forwarding. The codebase is built with CMake, uses protobuf for messaging, and relies on libraries like asio, OpenSSL, libvpx, libyuv, and zstd.
NanaBox is a virtual machine management tool for Windows, built using C++ and the Windows API. It utilizes the Windows.UI.Xaml namespace for creating the user interface and has a modular design with separate classes for different features. The application is actively maintained with recent commits and updates.
This repository provides a comprehensive, modular set of Bash scripts to automate the installation and configuration of Apache Guacamole—an open-source remote desktop gateway. The primary orchestrator '1-setup.sh' handles interactive prompts and silent install variables to deploy Guacamole server and client from source, integrate MySQL/MariaDB as the backend database, set up Nginx as a reverse proxy, and optionally configure TLS (self-signed or Let's Encrypt), multi-factor authentication (TOTP, Duo, LDAP), and extra UI features like quick-connect and session recording storage. The scripts are well-structured with extensive error checking, logging, distro-specific workarounds, and support for modular post-install add-ons. Though not a library for reuse, the code demonstrates solid shell scripting craftsmanship, security hardening (fail2ban integration, firewall rules), and separation of concerns. The repository serves as a turnkey deployment toolkit for production-grade Guacamole environments.
