A real-time network monitoring dashboard for Linux, built with SFML.
Visualizes active connections, network devices, HTTP traffic, system tool versions and external IP info - all in one graphical interface.
⚠️ Requires root privileges (sudo) - needed for packet capture via libpcap.
| Block | Description |
|---|---|
| System Info | Versions and status of: OpenSSH, Docker, OpenSSL, NetworkManager, systemd, iptables and more |
| Request Log | Live HTTP request capture via libpcap - method, path, source IP, timestamp |
| External IP | Your public IP, ISP and location via HTTPS API |
| Network Devices | All devices visible in ARP table - IP, MAC, interface |
| Connection Visualizer | Animated graph of active TCP/UDP connections with status colors |
| Library | Purpose | Install (Arch) |
|---|---|---|
| SFML 3.x | Graphics, window, events | sudo pacman -S sfml |
| libcurl | HTTPS requests to IP APIs | sudo pacman -S curl |
| libpcap | Packet capture | sudo pacman -S libpcap |
| xorg-xhost | Allow root to access display | sudo pacman -S xorg-xhost |
