NMLinux

NMLinux is a free, open-source network management toolkit for Linux and macOS that brings 29 network utilities into a single desktop application. Built with Python and PySide6, it targets sysadmins and power users who want a native GUI without juggling a dozen separate tools.

A universal right-click context menu connects every module — discover a host in the IP Scanner, right-click it, and send it instantly to Ping, Port Scanner, SSH, Traceroute, Topology, or Asset Inventory.

Analysis & Inspection — DNS multi-record lookup, WHOIS, TLS certificate inspector with expiry watchlist — Firewall viewer (iptables/nft), SNMP browser, SpeedTest

Remote Access & File Operations — SSH with embedded full PTY terminal (zsh/bash/fish, agent forwarding) — RDP, VNC, WinRM, SMB/NFS share browser — Built-in TFTP and HTTP file transfer servers

Inventory & Management — Asset Inventory: multi-host SSH/WinRM scan (OS, CPU, RAM, disk, uptime) — Connection Manager, Export Manager (JSON/Markdown/PDF), Command Palette (Ctrl+P)
