I moved myself to a new workstation and followed my previous steps to export my putty sessions.  This time around I am exporting my Virtual Infrastructure Client settings

  3. On the File menu, click Export
  4. In File name, enter a name for the registry file.
  5. Choose a location to save the file; You can now copy this file and import your the sessions data on the new system.

Tech-Short: Delete Virtual Switch in Hyper-V

And this happened . . .

I was introducing a change the Virtual Switch Manager of my Hyper-V host, where I attempted to give guest machines bridged network access.  After making my change I had lost access to the server.  On a good note, the server picked up a new address its virtual interface that I created.  However I am unable to connect to the Hyper-V services so I am taking steps to delete the interface and review my steps.

To do this I first attempted the following things:

Issued the command: Get-VMSwitch to list the name of the network adapter interface. I then attempted to remove the interface by entering:

After being prompted and selecting Y for “Yes” I was given an error:

Remove-VMSwitch : Failed while removing virtual Ethernet switch.
The virtual switch ‘Default VLAN’ cannot be deleted because it is being used
by running virtual machines or assigned to child pools.
The operation cannot be performed while the object is in use.
At line:1 char:16
+ Get-VMSwitch | Remove-VMSwitch
+ ~~~~~~~~~~~~~~~
+ CategoryInfo : ResourceBusy: (Microsoft.HyperV.PowerShell.VMTas
k:VMTask) [Remove-VMSwitch], VirtualizationOperationFailedException
+ FullyQualifiedErrorId : ObjectInUse,Microsoft.HyperV.PowerShell.Commands
.RemoveVMSwitchCommand

This error was thrown because of the virtual machine(s) I have running so I needed stop it (or them).

A quick issue of the command Get-VM to return the full name of the VM running in this lab followed by a quick issue of:

One all VM guests are off I was able to reissue the command Get-VMSwitch | Remove-VMSwitch at which point the previous IP became active again. A quick restart of the Hyper-V Server host and I was once again able to connect.

Now its time to learn what I did incorrectly to cause this issue.

TunnelBear – Simple, Private and Free

TunnelBear has just launched a Chrome extension that helps to protect your privacy on a Chromebook, Android, iPhone, iPad, PC & Mac

TunnelBear is a Canadian company famous for making super easy to use privacy tools. They specialize in VPN services that allow your phone and computers to be secure when using public WiFi hotspots. Their service also allows you to “tunnel” into another country to get around content blocking by governments or media companies.

Today TunnelBear is launching a public beta version of their new Chrome extension. When installed, it will protect everything you do in Chrome by running it through an encrypted web proxy.

For Chromebook users, almost everything you do should be encrypted, making it a great tool to have. For Windows, Mac, or Linux users, please note that only your Chrome connection will be secured – not the rest of your system’s traffic.

TunnelBear offers a free plan for those with low data usage, or a very cheap paid plan for everyone else.

Change Hostname On Windows Server 2012 R2 Server Core

Windows Server 2012 R2 Server Core is installed and now its time to change the hostname from the install default. To change the hostname I will issue the following command:

 

You will get the following message once completed:

Certain services, such as the Certificate Authority, rely on a fixed machine name. If any services of this type are running on WIN-BLABLA, then a computer name change would have an adverse impact.

Do you want to proceed (Y or N)?

Once completed the computer will need  to be restarted in order to complete the operation.

To this with the following command:

 

Retrieve MX records using nslookup

One of my new kids on the block asked me a question tonight; “Jermal, how do I get the mx record of a domain?”

To retrieve mx record information we need to use a tool called nslookup which is available in Windows and Linux

The quick syntax use is
