Is there a setting or extension that allows SSH/SFTP access to remote servers using ssh keys? I can’t seem to find one and the server I’m trying to access will only accept SSH keys for authentication.
File access via ssh has nothing to do with LibreOffice, even if the files happen to be office documents.
I am referring to the “Open Remote…” option that takes you to the connection manager. There, you can add an SSH connection. It gives the option to authenticate using user/pass, but does not appear to have a method of using an SSH key to authenticate. Is there a way to use an SSH key here or have it reference the file ~/.ssh/config?
Mount that remote device in your operating system. The "Open Remote… " dialog is dysfunctional.
