Hi, I’m trying to set up a Paraview client/server. I’m using the client in Windows & server in Ubuntu. I’m writing the pvsc file to set up, and I’m stuck at authentication.

when I try to connect to a server, I can enter the password in the terminal, but there is no automated setup. For this, I’m playing around with the delay option by setting a longer time so that I can enter the password before the client tries to connect to the server.

I’m trying to set up a public/private key setup, but I don’t see any tag in to pass a key file to authenticate.

Help me with the correct approach to authenticate clients with the server from a windows machine.

I have set the SSH key, but how do I pass it to PVSC, i mean what is the tag for it in `<SSHConfig>`

currently, I’m using as below, though it works there is no standard way

```auto
<SSHConfig user="$SSH_USER$">
	  <Terminal/>
	  <SSH exec="ssh -i <PATH>" />
	</SSHConfig>

```

I’m looking for something like `<SSHIdentityFile>` or something similar

There is nothing to put in the pvsc, it will “just work”.

So `<SSH exec="ssh -i <PATH>" />` this the correct way to use the ssh key?

Yes, if you want to use a specific ssh key, but you should be able to set that in your `.ssh/config`

</div>

how can i set up ssh-add for autologin with this setup in Windows instead of passing `ssh -i` ?  
because in the default terminal(CMD) it doesn’t hold values & prompt asks to enter password.
