Add-PSSnapin through SSH - InvalidArgument ?

[Diegasus]

Hello,
i'm trying to start PowerShell on the Veeam Server through SSH connection. This work but when i try to add the VeeamPSSnapIn i have some errors.

I have installed freeSSH (i'm testing with freeSSH, in the future the connection will be started from a Linux server) on the VeeamBackup Server. I open the SSH connection from my laptop , i can reach the Veeam Server and start powershell:

Code: Select all

C:\Windows\system32>cd C:\Users\Veeam
C:\Users\Veeam>powershell
Windows PowerShell
Copyright (C) 2009 Microsoft Corporation. All rights reserved.
Veeam@xxx.xxx.xxx.xxx's password:
PS C:\Users\Veeam>

The command Get-PSSnapin return a list of snapin. The VeeamPSSnapIn is not in the List, also i try to add the VeeamPSSnapIn:

Code: Select all

PS C:\Users\Veeam> Add-PSSnapin VeeamPSSnapIn
Add-PSSnapin : No snap-ins have been registered for Windows PowerShell version
2.
At line:1 char:13
+ Add-PSSnapin <<<<  VeeamPSSnapIn
    + CategoryInfo          : InvalidArgument: (VeeamPSSnapIn:String) [Add-PSSnapin], PSArgumentException
    + FullyQualifiedErrorId : AddPSSnapInRead,Microsoft.PowerShell.Commands.Ad
   dPSSnapinCommand

PS C:\Users\Veeam>

but i have an error.... InvalidArgument...

When i try on the Veeam Server (starting the cmd, then powershell, Add-PSSnapin..) it work...

Why when i try with SSH it don't work? Is something not correct loaded when i start powershell on the SSH connection?
Any idea?

I will search a solution, but if you have some feedback this will be appreciated

Are you logging in through SSH with an administrative account or the same account you installed Veeam with? Make sure your account is added to the local administrative group.

Hi Sethbartlett,

yes i'm using a user "veeam" that is in the Administrators group and i'm logging in through ssh with this user.
This should not be the problem.

Try doing Remote Powershell locally from the veeam box and see if you run into the same issues or not.

Hi,
i will now explane two case that i tested:
In the first case i login on the Veeam Server and i execute the command on the cmd prompt windows (NOT launching PowerShell from Veeam B&R Interface).
In the second case i will do the same but i start an SSH connection to the Veeam Server from a remote client.

Case1:
- LogIn to the server with the user "veeam" (the user is the installation user for veeam and is in the Administrators group)
- Start cmd prompt
- Start powershell

- check which SnapIn are registered

Code: Select all

PS C:\Users\Veeam> Get-PSSnapin -registered

Now i see that "VeeamPSSnapIn" in already registered and i can load it.

Code: Select all

PS C:\Users\Veeam> Add-PSSnapin VeeamPSSnapIn
PS C:\Users\Veeam>

Now if i re-check the loaded SnapIns i find the new one

Code: Select all

Now when i try to run a VBR cmdlet, for example

Code: Select all

PS C:\Users\Veeam> Get-VBRJob

it work.

This case work as expected

Case2:

- login from my client to the Veeam Server through SSH:

Code: Select all

ssh Veeam@xxx.xxx.xxx.xxx

Code: Select all
