MTR Matrix

Real-time MTR (traceroute) monitoring from multiple source IPs to multiple destinations, displayed in a web-based matrix view.

Features

• Multi-source MTR: Run MTR from multiple source IPs simultaneously
• Real-time updates: WebSocket-based live updates
• Matrix display: Sources as columns, destinations as rows
• Hover details: TTL, IP, PTR (reverse DNS), latency stats, packet loss
• Shared destinations: Continuous monitoring to configured destinations
• Custom destinations: Users can add temporary destinations (60s duration)
• Dynamic interface binding: Automatically detects interface for each source IP

Requirements

• Linux (uses raw sockets)
• Root privileges or CAP_NET_RAW capability
• Rust 1.70+

Installation

cargo build --release

Configuration

Edit config.toml:

custom_duration_secs = 60
max_custom_per_user = 10
max_custom_global = 75

[[sources]]
name = "source1"
ip = "192.168.1.1"

[[sources]]
name = "source2"
ip = "192.168.1.2"

[[destinations]]
host = "1.1.1.1"

[[destinations]]
host = "8.8.8.8"

Network Setup

Run the setup script to configure IPs and routing:

sudo ./setup-network.sh

This script:

• Adds source IPs to the interface
• Configures policy routing via iptables marking
• Sets up the gateway route

Running

sudo ./target/release/mtr-matrix

Access the web UI at http://localhost:10000

Usage

• The matrix shows average latency to each destination from each source
• Hover over a cell to see detailed hop-by-hop information
• Use the input field to add custom destinations (limited per user and globally)
• "N/A" indicates the destination is unreachable from that source
