PowerCLI Invoke-VMScript Error

[SheldonA]

Hello,

When running the Invoke-VMScript commandlet I receive an error similar to the following:

Invoke-VMScript :    Invoke-VMScript         An error occurred while sending the request.

At line:1 char:1

+ Invoke-VMScript -ScriptText "get-service" -VM $VM -GuestUser Administ ...

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : NotSpecified: (:) [Invoke-VMScript], ViError

    + FullyQualifiedErrorId : Client20_VmGuestServiceImpl_DownloadFileFromGuest_DownloadError,VMware.VimAutomation.ViC

   ore.Cmdlets.Commands.InvokeVmScript

My code is as follows:

add-type @"

using System.Net;

using System.Security.Cryptography.X509Certificates;

public class TrustAllCertsPolicy : ICertificatePolicy {

    public bool CheckValidationResult(

        ServicePoint srvPoint, X509Certificate certificate,

        WebRequest request, int certificateProblem) {

        return true;

    }

}

"@

$AllProtocols = [System.Net.SecurityProtocolType]'Ssl3,Tls,Tls11,Tls12'

[System.Net.ServicePointManager]::SecurityProtocol = $AllProtocols

[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy

Invoke-VMScript -vm "test centos7" -scripttext "ls" -guestuser root -guestpassword #####

I tried the resolution outlined in the following thread with no success:

Error running Invoke-Vmscript - An error occurred while sending the request. FullyQualifiedErrorId :...

I'm running PowerCLI 12.0 on vSphere 6.5.0.30000 with VMware Tools version 10346.

Is my code sound or is there something that I missed?

Thanks in advance.

The error seems to occur when the Invoke-VMScript downloads the file with the output from the target VM.

As the user in the thread, you pointed to also experienced, you might want to try my Invoke-VMScriptPlus with the Verbose switch.

That should give you more information on what goes wrong.
And while you are at, try the NoIPinCert switch as well.

Hello,

I tried your script and received the errors below.  I configured an IP on the VM and put hosts file entries on the host running the script.  I did some research on the error and found references to proxy configurations which I am not using.

Is there perhaps a proxy between your station and the VM?

Also, did you use the -NoIPinCert switch or not?

Update: I just noticed you stated there is no proxy involved.

Update2: could it be that port 902 between your station and the ESXi node on which the target VM is running, is not open?

[SheldonA]

Looks like port 902 wasn't opened from the host I was running the script from to the ESXi hosts. That what was causing the issue.

Thanks a lot for your help.

We have two vCenters BLR and NJDC. When I have executed the below script ,it is working in NJDC VC and not working in BLR VC.Please find the reference screenshots.

add-type @"

    using System.Net;

    using System.Security.Cryptography.X509Certificates;

    public class TrustAllCertsPolicy : ICertificatePolicy {

        public bool CheckValidationResult(

            ServicePoint srvPoint, X509Certificate certificate,

            WebRequest request, int certificateProblem) {

            return true;

        }

    }

"@

[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy

        $VMName = 'XXXXXX'

        $vCenterIP = 'https://XXXXXXXX/sdk'        

        $vCenterUser=  'XXXXXX'

        $vCenterPassword = 'XXXXXXX'

        $desktopGuestUser = 'XXXXXXX'

        $desktopGuestPassword = 'XXXXXXXX'

        $APIUserName = 'XXXXXXX'

        $APIPassword ='XXXXXXX'

        $DomainPassword = 'XXXXXXX'

        $vCenterIP=$vCenterIP.split('/')[2];

        $Password=ConvertTo-SecureString -string $vCenterPassword -AsPlainText -Force

        $ViServerCred=New-Object System.Management.Automation.PSCredential($vCenterUser,$Password)

Can you help with this? We have already allowed port 902.when run the below script for one of VCSA.it is not showing output.

[LucD]

Try the same with my Invoke-VMScriptPlus function and use the Verbose switch.
It might provide more feedback.
