Powershell – Get GPO Report for an Active Directory domain

Sometimes you want to be able to quickly create a GPO report for an Active Directory domain. And ofcourse you can do this manually using the GUI as well, but with a PowerShell script you can automate and schedule it.

So here’s my script that will automatically save a time stamped GPO report for the current domain.

 

Powershell – Get Percentage of Pysical and Virtual Servers from your VMware and Cisco UCS combined for each location

In a previous blog post I’ve already shown this script that use PowerCLI to get the percentage of physical and virtual servers from your VMware environment for each Virtual Center server. This script however only took into account ESX hosts and VM’s in each Virtual Center server separately.

This means that:

  • The UCS blades weren’t taken into account as physical servers.
  • No percentage was being calculated for each physical location.

This new script automates determining for each location the number of physical and virtual servers in VMware vSphere and Cisco UCS.

PS: You can get more detailed information from the script, but it has been disabled using comments by default.

PowerShell – Get UCS Blade Count

PowerShell has been adopted by many companies already including VMware and Cisco with its Unified Computing System (UCS).

This simple script will use the Cisco UCS PowerTool to connect to UCS and determine the blade count for each UCS server you’ve defined.

PowerShell – Get the percentage of physical and virtual servers from your VMware environment

With the current focus on Corporate Social Responsibility (CSR) including Green IT, it might be important to know what percentage of servers has been virtualized.

This script I made will use PowerCLI to get the percentage of physical and virtual servers from your VMware environment for each Virtual Center server. You can specify multiple Virtual Center servers if desired.

Security – Java releases update for major Java vulnerability

Last sunday I warned about a major vulnerability in Java.

It wasn’t expected that Java would come have an update available this quickly, but it is good that they did. So be sure to update to Java 7 Update 11 : http://java.com

Free training – Microsoft Virtual Academy (MVA) hosting 3 virtualization related Jump Starts

Microsoft Virtual Academy (MVA) is hosting 3 virtualization related Jump Starts in January and February:

  1. Introduction to Hyper-V Jump Start (January 24th, 2013)
  2. Microsoft Virtualization for VMware Professionals Jump Start (January 30th, 2013)
  3. Microsoft Tools for VMware Migration and Integration (Late February)

I’ve attended a couple of Jump Starts including those of Office 365, Windows 8 and Windows Server 2012 already and I think it’s a great way to quickly get up-to-date about a subject. Also there’s a great team of people working behind the scenes to answer questions and provide more detailed resources. Other attendees often also share their experiences and provide valuable insights.

The links above provide include a course outline and a link to register for the Jump Start.

I hope to see you there.

Security – Major Java vulnerability, don’t become a victim

[EDIT 14-01-2013]

Oracle release Java 7 Update 11 to fix this security issue. Be sure to update: http://java.com/

[EDIT]

Normally when I read about security vulnerabilities, I don’t really get a sense of urgency.

With the current Java vulnerability however, I do feel like people have to act quick because there are so many respected companies and even countries actively taking action:

Apparently this vulnerability is actively being exploited already and Oracle hasn’t released a Java fix yet. You might want to consider a combination of the options below:

Personally I like the way FireFox is handling the issue because it blocks by default, but allows users to easily override this behavior for specific sites. Also I’m getting quite fed up with all these Java security vulnerabilities lately 😦

I’d like to know what you’ll be doing. Have you or are you going to disable Java ? Which methods will you use ? Why ?

Home LAB – Virtualization and how to enable nested ESXi and other hypervisors in VMware vSphere 5.1

As a passionate ICT person, I work with multiple virtualization products including Microsoft Hyper-V and VMware vSphere.

At home I’m running Server 2012 with Hyper-V in my home lab and even though it works perfectly, I miss the option to be able to run multiple other hypervisors beneath it like by example multiple Hyper-V, VMware ESXi or Citrix XenServer instances.

With VMware products like VMware Fusion, VMware Workstation you can enable this with only a couple of minor adjustments as described in these great articles:

For me personally, I’ll stay with my Hyper-V based home server and my Windows 8 Client with Client Hyper-V installed. For testing purposes however, I’ll have to use VMware Workstation 9 on my Windows 8 machine.  (even though I have Client Hyper-V installed). This way I can still run other hypervisors when needed.

I still hope though that Microsoft will add a similar feature to Hyper-V in the future.
