Hi,
I am using Labview 2025 Q3 Windows 64 bit on my machine.
My machine is connected to a machine running on Linux (Fedora 64 bit) through ethernet cable, I am trying to connect to the linux machine using SSH library through labview. However I am getting standard error "Host key verification failed".
I have followed steps given in this article
What could be the possible mistake?
PS: I tried running same command in windows powershell and am able to login to the linux machine.

The article isn't very clear on what to actually type, but I believe that "user" is the user name and "IP_Address" is the IP address of the Linux box. I don't think you're supposed type it in verbatim. Just in case you hadn't thought of that already.

Hi billko,
Thanks for the reply. I have carefully replaced user with the actual user name and IP address with the valid IP address. Also I am able to communicate with Linux box using the very same user name and IP address using windows PowerShell.
The issue is faced only when I try to communicate through Labview. So I am trying to understand what makes it different in labview or am I missing something in the code.

You can set an option to enable trust on first use. Does it work then?
Trust on First Use (TOFU)
Why do you execute an SSH command on the remote host? The LabVIEW SSH library does not maintain a connection, so this will not work. I also do not think that it supports jump hosts.
