Remote powershell scripts fail but local works

[lukel_3991]

I'm running a simple one-liner (ipconfig /all) to test a new Otter install and keep getting this error. It only happens when I run on a remote machine. Running against the Otter localhost work fine. I'm using powershell remoting to access, not the agent.

Hi @lukel_3991,

What version of Otter are you running and are you running it on Windows or Docker?

Thanks,
Rich

Hey Rich,

I'm running on windows server 2019 standard and Otter v3.0.15.

@lukel_3991 thanks.

So this works totally fine if you're using localhost instead of computername.domain.com then And then, computername.domain.com is a Windows server?

If that's the case, it means the agent (which is connected via PowerShell Remoting) isn't fully loading; basically, the Scripting extension isn't loading, or had an error.

Can you try using a different Temp path? Maybe there's a relation....

Thanks,
Alana

Yes that's all correct. I tried with a different local path and still no dice. The initial Otter folder is created but the extensions never get transferred.

Just for kicks I tried copying over the extensions from the otter server to C:\Otter\HostedAgent\extensions. This time it worked.

I can work around that by loading extensions in advance but the cleanup step was not able to delete the temp folder. Is this an easy fix?

Hi @lukel_3991,

I think we have two different issues that are happening here. The first one it seems to not be synchronizing over the extensions. What version of PowerShell do you have installed on your remote server and the otter server? The PowerShell based agent-less servers connect using PSRemoting over WSMAN. Could you please try to connect to your remote server using Enter-PSSession in PowerShell on your Otter server and try to run some commands to make a temp folder and write a file to it using the same credentials Otter users to connect to that server? It almost feels like there may be a permissions issue.

The other issue seems like their could an issue with your OtterScript itself. Would you be able to share the OtterScript you are trying to run?

Thanks,
Dan
