Traceroute Implementation in Rust

A simple traceroute utility written in Rust using the pnet crate. This program sends ICMP Echo Request packets with increasing Time-To-Live (TTL) values to map the network path to a specified destination IP address.

Features

• ICMP Packet Handling: Sends ICMP Echo Request packets and listens for responses.
• TTL Management: Increments the TTL value to trace each hop to the destination.
• Round-Trip Time Measurement: Calculates the time taken for each packet to reach the hop and return.
• Destination Detection: Stops tracing once the destination is reached.

Prerequisites

• Rust: Ensure you have Rust and Cargo installed. You can install Rust using rustup.
• Administrator Privileges: Root or administrator rights are required to send raw ICMP packets.

Installation

1. Clone the Repository

   git clone https://github.com/junfengyu/traceroute_rust.git
   cd traceroute_rust

2. Update Dependencies

   Ensure that your Cargo.toml includes the necessary dependencies:

   [dependencies]
   pnet = "0.28.0"
   pnet_packet = "0.28.0"
   pnet_transport = "0.28.0"

   Then run:

   cargo update

3. Build the Project

   Build the release version for optimal performance:

   cargo build --release

Run the Program**

Run the program with root privileges, specifying the destination as a command-line argument:

• Linux/macOS:

  sudo ./target/release/traceroute-rust example.com

• Windows:

  Open the Command Prompt or PowerShell as Administrator and run:

  .\target\release\traceroute-rust.exe 8.8.8.8

Example Output
