I'm currently setting my laptop and raspberry pi to have a sshfs link between the two for quick file transfer. I was able to log into the users of each machine using my password with no issue, so that allows me access to their directories. However, I'm hoping to be able to mount the root of each machine to each other. When I attempt to do this using
sshfs email@example.com:/ /path/to/mount/
It prompts me for the root users' passwords (for each machine). However, the password which I use on each machine to access the root user is not working. Is there a default password that root users tend to have when it comes to SSH?
