I cannot login as root to my mac mini from a linux computer

From my Linux desktop (Fedora), I am trying to log in as root to my Mac mini computer.

$ ssh root@my-mac-mini
Connection closed by 10.0.1.12

10.0.1.12 is the mac mini ip address.

In the log file /var/log/system.log, I see:

Apr 30 11:57:05 my-mac-mini.my-domain.com sshd[8903]: fatal: Access denied for user root by PAM account configuration [preauth]

With more verbose:

$ ssh -v root@my-mac-mini

In /etc/sshd_config, I have

PermitRootLogin yes

How can I fix this?

Solution 1:

I had similar problem which is solved by following answer:

Check your Remote Login settings under System Preferences > Sharing > Remote Login

Specifically, who is allowed to log in?
