Hi,

It is not clear if you set this up twice (A->B and B->A)?

The tutorial you mention sets up a passwordless client (A) to server (B) connection for (open)SSH for a specific user. It does not set up the reverse (passwordless from server (B) to client (A).

Hope this clears things up.

Try to be precise -- following to your documentation, there's one server and one client. It says, "The system from which the ssh session is started via the ssh command is the client."

Can you be more specifc? How does it fail? What does the server log? It can be helpful to run in the server debug mode, and maybe on a different port, e.g.,
Root privilege is lets it read the host key file. There are ways around this (and good reasons not to be root when you don't need to), but sudo is simplest here.

I advise to use ssh, and not to use rlogin.
