I'm here again guys.
Now I have a little small doubt.
After I make the login without password between Front-end and my node.
I see this out:
*oneadmin at PacsOnCloud-FrontEnd:~$ ssh oneadmin@<my-ip>

If we look closely, we see that the prompt for oneadmin remote only has a*$
*prefix.
It is look like a limited prompt. I can do nothing with this kind of
prompt. ls, cd, cat, nothing works.
Only the command 'exit' works fine.
Is that correct?
Any hints?
Thank you so much.
Best regards.
