ilo4ctrl

ilo4ctrl is a simple command-line tool designed to control the fan speeds of HP servers via the iLO (Integrated Lights-Out) interface using SSH.

Prerequisites

• .NET 9.0 SDK (to build the project)
• An HP server with iLO access (SSH enabled)

Configuration

Before using the tool, you must create a configuration file to store your iLO connection details.

1. Create the directory: ~/.ilo4ctrl
2. Create a file named config.ini inside that directory.
3. Add the following content, replacing the placeholders with your actual iLO credentials:

[ilo]
host=YOUR_ILO_IP_ADDRESS
username=YOUR_ILO_USERNAME
password=YOUR_ILO_PASSWORD

Usage

Run the tool providing the desired fan speed as a percentage (0-100).

./ilo4ctrl <fan-speed-percentage>

Example

To set the fans to 35% speed:

./ilo4ctrl 35

Building

You can build the project using the standard dotnet build command.

Building a Self-Contained Binary

To build a single, self-contained binary for Linux (x64) that does not require the .NET runtime to be installed on the target machine, use the following command:

dotnet publish -c Release -r linux-x64 --self-contained true /p:PublishSingleFile=true /p:IncludeAllContentForSelfExtract=true

The resulting binary will be located in the bin/Release/net9.0/linux-x64/publish/ directory.
