DNP3 Time Sync Tool (dnp3time)

dnp3time is a CLI tool designed to synchronize time on systems using the Distributed Network Protocol (DNP3). It enables users to send time synchronization commands to DNP3 outstations with either user-specified or interactively provided timestamps.

Features

• Synchronize time to DNP3 outstations with user-defined timestamps.
• Interactive prompting for timestamp entry.
• Support for LAN time-sync procedure per DNP3 standards.
• Cross-platform builds for Linux and Windows.

Installation

dnp3time is available on crates.io. You can easily install it using cargo:

cargo install dnp3time

This will install the dnp3time binary and make it available globally on your system.

From Source

Alternatively, you can build the tool from source. First, clone the repository and use cargo to build it:

git clone https://github.com/ladderlogix/DNP3TimmingAttack.git
cd DNP3TimmingAttack
cargo build --release

The binary will be located in the target/release/ directory.

Prebuilt Binaries

Prebuilt binaries for Windows and Linux are available on the Releases page. You can download them directly instead of building the tool manually.

Usage

Run the tool with the following command:

dnp3time --ip <outstation_ip:port> --time <YYYY-MM-DD HH:MM:SS>

Example:

dnp3time --ip 10.152.152.152:20000 --time "2023-11-12 14:23:00"

Alternatively, you can run the command interactively without the --time flag to input a timestamp at runtime:

dnp3time --ip 10.152.152.152:20000

Arguments

• --ip (-i): The IP address and port of the DNP3 outstation (default: 10.152.152.152:20000).
• --time (-t): The target date and time in the format YYYY-MM-DD HH:MM:SS (optional).

Example Workflow

A typical use case involves specifying the outstation's IP address and port along with the desired timestamp. If the timestamp is omitted, the tool will prompt for it interactively. This makes the tool flexible for both pre-configured and ad-hoc time synchronization.

CI/CD Workflow

This repository includes CI/CD pipelines via GitHub Actions for:

• Building binaries for Windows and Linux.
• Code signing for Windows binaries using Azure Trusted Signing.
• Creating releases and publishing prebuilt binaries to GitHub Releases.
• Publishing the crate to crates.io.
