I found myself wanting to enable the SSH service on my ESXi hosts. I could use Host Profiles to enable it but I decided to PowerShell script it! To enable SSH there are three parts to it:
You will need to start the SSH service and set it to Start and Stop with Host:
And you will need to suppress the SSH is enabled warning message:
