A Journey Through Discovery

  • ESXi 6.5 STIG Welcome Message

    So the ESXi 6.5 Security Technical Implementation Guide (STIG) finally released in May 2019. Unfortunately, some of the items I would have liked to see fixed or updated were not. One of the biggest pet peeves is the Annotations.WelcomeMessage advanced setting check. This setting updates the /etc/vmware/welcome file in the filesystem. If the STIG fix…

  • Making a REST API Request in vRealize Orchestrator

    This was a tough nut to crack for me. I definitely don’t ever want to struggle through learning this topic again. I hope if you are reading this, I can save you a ton of lost time. I use Postman to scope out the concepts before trying to translate them in vRealize Orchestrator (vRO). When…

This is how it all started…

I started this site with the intent to aggregate as much information as possible in one place. I use this to record lessons learned or frustrating configurations I have experienced on the job or just tinkering (learning) and just couldn’t find a better resource available. I have tried to be as thorough and accurate as possible, but technology is rapidly evolving and every environment is different. I may miss things along the way and my setup most likely differs compared to yours.

I hope you find this site has some value to you.
