Sorry, Tomas, it's not Gene, it's me who has a special question
concerning ssh.
If you create a new user account ("test"), doing as root
adduser --disabled-password test

How can you access this new account to generate an ssh key pair there?
I cannot login to the account selecting "test" as user in the login
screen on system startup, it's deactivated.
I cannot try accessing it by ssh because I need to generate a key pair
first. Could one generate a key pair for "test" from another account?

If I try
ssh test@localhost
ssh: connect to host localhost port 22: Connection refused

or, temporary enabling password authentication for a moment in
sshd_config, it prompts for a password (that has never been created
because of the --disabled-password option, see above).

Or, what am I missing?

Thanks in advance.

Stephan

I also read the doc you linked to in your other message of this thread,
but I cannot find my use case.
