Creating a Domain Trust with Red Hat IdM/FreeIPA and Active Directory

This is something I wrote quite some time ago, and some how it was never published. Apologies for the late release.

Splunk is a web based tool that can help you filter through all of those logs, but give you the exact results you are searching for.

This article will take you through setting up Splunk in your environment, and how to quickly search for information for exactly what you are looking for.

Adding CloneZilla to your existing PXE deployment model

Firstly, thanks again to Gavin Spurgeon for his assistance with getting this solution working smoothly.

Two days ago I wrote an article about setting up PXE network booting. This is very useful when it comes to quick provisioning with Kickstarts or other utilities.

In this article, I’ll be covering for those Windows users amongst you, how to use CloneZilla (Open Source alternative to Symantec Ghost) combined with PXE to quickly deploy your company Standard Operating Environments (SOE’s).
