MudNetMon

Introduction

MudNetMon (Mudfish Network Monitor) is a terminal-based tool that shows real-time network usage for each program on your computer. You can see which applications are using the network and how much data they are sending or receiving.

MudNetMon works correctly even when you are connected to a VPN (such as Mudfish)—it shows which program generated the traffic, not the VPN.

Features

• Per-program monitoring: See how much network traffic each program uses
• Connection details: View which servers (IP address and port) each program connects to
• VPN-aware: Shows the correct program even when VPN is active
• Export: Save the data to a CSV file for later review

Platform Support

Running

MudNetMon must be run with Administrator (Windows) or Root (Linux/macOS) privileges to monitor network traffic.

• Windows: mudnetmon.exe binary is found at the Mudfish installation directory. Normally it's under C:\Program Files (x86)\Mudfish Cloud VPN\ folder. Right-click the program and select "Run as administrator".
• Linux / macOS: Run with sudo (e.g., sudo ./mudnetmon)

On Windows, mudnetmon will open in Windows Terminal if it is installed, for a better display.
