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.
Dublin Traceroute is a NAT-aware multipath traceroute tool that extends the Paris-traceroute technique to enumerate ECMP load-balanced paths and detect NATs. It forges UDP packets with custom payloads to control the UDP checksum, which is used as a per-flow identifier and embedded in the IP ID field for NAT correlation. The system listens for ICMP Time Exceeded and Destination Unreachable responses, matches them to sent probes using IP ID (IPv4) or payload length (IPv6), and computes a NAT ID from checksum differences. Output is provided in JSON or DOT format for visualization. The repository contains two independent implementations: a primary C++ library/CLI using libtins and jsoncpp, and an experimental Go implementation with IPv6 support and additional tooling (routest for integration testing). The Go implementation demonstrates cleaner separation of concerns with reusable network protocol modules (ICMP, UDP, IPv6) and a layered protocol abstraction.
