Invoke-NcSsh complaining PuTTy not installed when executed from scheduled tasks

eugene_t — Wed, 04 Jun 2025 12:06:17 GMT

Hi all,

I have a .ps1 script that consists of a combination of PoSh cmdlets and Invoke-NcSsh. The script works as expected when it's executed from PoSh but throws errors saying "Error: Please install putty ( version putty-64bit-0.70(64bit) or putty-0.70-installer(32bit) ) on your machine to use this cmdlet.. Code: . Message: Unable to connect <cluster>" when the script is triggered from a scheduled task.

PuTTy is installed and permissions of its registry key is configured as reported elsewhere in this forum. Does anyone else have this problem / knows how to rectify this?

Info:

Windows Server 2012 R2

PoSh 5.1.14409.1018

NetApp PoSh toolkit version 4.5.0

Hi,

There have been a number of issues with Invoke-NcSsh and Putty

Have you considered using "Invoke-NcSystemApi" as an SSH replacement? What SSH commands are running in your script?

Hi Matt,

Yeah I've considered using "Invoke-NcSystemApi" as an alternative but haven't got round to testing it.

These are the "Invoke-NcSsh" commands I'm trying to run,

Invoke-NcSsh -Command "system timeout show"
Invoke-NcSsh -Command "security ssh show"
Invoke-NcSsh -Command "vserver services web show -ssl-only false -name spi"
Invoke-NcSsh -Command "vserver services web show -ssl-only false -name ontapi"
Invoke-NcSsh -Command "system services ndmp show"

I'll be more than happy to switch to their native cmdlets if one exists and if not, "Invoke-NcSystemApi" but I'll probably need some help with "Invoke-NcSystemApi".

have been using putty-64bit-0.70-installer.msi for NetApp_PowerShell_Toolkit_9.6.0.msi.

I also make the regestory change to Local Machine software\simontatham and Add the local User/ System Full Control in the permissions.

I find running powershell as administrator works well.

Thanks PhillipUdel but I have no problems with executing normally "Invoke-NcSsh" from a PoSh console. The problem only comes in when the command is executed from a scheduled task.
