PTR Record error in Failover clustering

"The PublishPTRRecordsWarn property for network name 'Name: xxxxx' is set to 1 For the current cluster configuration this value should be set to 0."

This is one of the most common error of cluster validation people encounter with. It is best practice to allocate Static IP addresses for the cluster nodes but mostly engineers forget to correctly configure the network settings.
PublishPTRRecords Property is enabled when your cluster node is getting IP address dynamically from a DHCP Server because in that situation Your DNS server will not be aware of the newly assigned IP of the node.

atleast the PTR Record will not be updated even if you enable DDNS setting on your DHCP Server. hence if you are using Static IP then no need to enable this setting.

Change the value to zero and run the cluster validation wizard again.

Spoofing MAC Address on Android Devices

Introduction to MAC: 
A Media Access Control address (MAC address) is a 12-character unique identifier assigned to a specific piece of hardware such as the network adapter of your WiFi device. In simple words, a MAC address can be used to uniquely identify your Android phone on the Internet or the local network.

Spoofing MAC Address on Android Devices:-

Even though MAC address is embedded on the hardware device during manufacture, it can still be spoofed to input a new one of your choice. Here is a detailed instruction on how to spoof MAC address on your Android phone.

Before you spoof the MAC address, you need to record the original/current MAC address of your device which can be done according to the instruction below:

1. On the Home Screen of your phone, tap Menu button and go to Settings.
2. Tap About Device and go to Status.
3. Now scroll down to record the 12-digit code shown under Wi-Fi Mac address. An address would read something like:
   
   1	Example MAC address: E5:12:D8:E5:69:97

Requirements for Spoofing the MAC Address:-

• Rooted Android Phone.
• BusyBox app installed on your phone.
• Once BusyBox is installed, you need to install Terminal app.

Once the above requirements are satisfied, follow the instructions below to spoof your MAC address:

1. Open the Terminal app and type the commands as listed below:

1	$ su [HIT ENTER]

1	$ busybox iplink show eth0 [HIT ENTER]

(This will show your current MAC address, just for your confirmation).

2. Now, type the following command:

1	$ busybox ifconfig eth0 hw ether XX:XX:XX:XX:XX:XX [HIT ENTER]

(In the above command, replace XX:XX:XX:XX:XX:XX with your new MAC address)

3. You have now spoofed your MAC address successfully. To check for the change enter the following command again:

1	$ busybox iplink show eth0 [HIT ENTER]

(Now you should see your new MAC address)

Please suggest Customer to engage with OS vendor and troubleshoot further on bugcheck error to avoid system reboot in future.

LiveCD Player Virtual Machine

LiveCD Player Virtual Machine

I've used LiveCDs in the past for checking out new operating systems or applications. They are a very handy way to do this without having to trash a computer... Then VMWare came along. It was easy to create a VM and try out new stuff. But that still took time. I found myself going back to playing with LiveCDs because I could boot into a pre-configured environment. One that looks just like the developer wanted it to look (provided you have all the right and supported hardware). The best way to do this would be if every developer realized the power of virtualization and made a VM for their project. But since they don't all do that and some still take the time to do a LiveCD, I've now gone to booting LiveCDs within virtual machines. Normally you'd have to be using VMware Workstation to pull this off... (And, yes, I know there are tools out there for creating VMs, but I figured this would just be easier.) But now with Player being free and all, it is something that you can have ZERO virtualization experience and get up and running LiveCDs on your PC - within a virtual machine - in no time flat. I'm assuming, though that you have VMware Player or Workstation installed. If you don't go here to get player. 1) First, download and unzip this file. Don't worry, this file is only about 4kb in size (and it is only that large because I included a 2gb drive since some LiveCDs were complaining about the lack of a hard drive).

2) Then download the LiveCD of your liking. For this example I downloaded the Knoppix version 4 LiveCD. 3) Once you have the LiveCD ISO file on your computer, copy or move it to the folder where you extracted the files in step 1. and rename the file "livecd.iso" I put a blank file there with that name as a placeholder. You'll need to delete it before renaming your real LiveCD ISO. 4) Now that the files are in place it should look something like this: 5) Now you should be able to open the vmx file with VMware player or workstation... Here's the splash screen of knoppix starting and then a screen-cap of the whole desktop after it booted:
