Note: This tip requires PowerShell 2.0 or above.
A few days ago, I was working on setting up Kemp Azure VLM. I will talk about this more in a detailed post later.
So, as part of this process, I had to upload the Kemp Azure VLM VHD to my Azure storage using Azure PowerShell cmdlets. However, my home proxy was not letting me do that and there was no way to provide proxy credentials when using Azure cmdlets. So, essentially, things like Add-AzureVHD will fail with a 407 error.
PS C:\> Add-AzureVhd -LocalFilePath C:\Scripts\LoadMaster-VLM-7.0-3-Azure.vhd -Destination "http://mystorage.blob.core.window s.net/kemp/kempvlm.vhd" Add-AzureVhd : "An exception occurred when calling the ServiceManagement API. HTTP Status Code: 407. Service Management Error Code: <NONE>. Message: <NONE>. Operation Tracking ID: <NONE>." At line:1 char:1 + Add-AzureVhd -LocalFilePath C:\Scripts\LoadMaster-VLM-7.0-3-Azure.vhd -Destination ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : CloseError: (:) [Add-AzureVhd], ServiceManagementClientException + FullyQualifiedErrorId : Microsoft.WindowsAzure.Management.ServiceManagement.StorageServices.AddAzureVhdCommand
That is not a very friendly message but there is an easy way to resolve the problem with a little help of .NET:
[System.Net.WebRequest]::DefaultWebProxy.Credentials = [System.Net.CredentialCache]::DefaultCredentials
The DefaultCredentials property of System.Net.CredentialCache represents the current security context in which the application is running. For a client-side application, these are usually the Windows credentials (user name, password, and domain) of the user running the application.
PS C:\> Add-AzureVhd -LocalFilePath C:\Scripts\LoadMaster-VLM-7.0-3-Azure.vhd -Destination "http://mystorage. blob.core.windows.net/kemp/kemp.vhd" -Verbose MD5 hash is being calculated for the file C:\Scripts\LoadMaster-VLM-7.0-3-Azure.vhd.
