Linux-Server-SSH fragt ständig nach dem Passwort. Was ist die richtige Konfiguration, was fehlt?

Linux-Server-SSH fragt ständig nach dem Passwort. Was ist die richtige Konfiguration, was fehlt?

Ich versuche, eine Verbindung zum SSH2-Server herzustellen. Ich kann mich per Passwort verbinden, aber ich musste SSH einrichten, also habe ich es ssh-keygenlokal erstellt und mit dem Befehl auf den Server kopiert ssh-copy-id root@IP_ADDRESSund noch einmal überprüft, es ist im Ordner gespeichert ~/.ssh/authorized_keys.

Ich habe es geändert homeund .sshund, authorized key permissionsaber nichts scheint zu helfen und der Server fragt ständig nach dem Passwort.

chmod go-w ~/
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

Außerdem habe ich nachgeschaut, /etc/ssh/sshd_configob alles in Ordnung ist. Nachfolgend sind die Konfigurationen aufgeführt

RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile      %h/.ssh/authorized_keys

Ich habe den SSH-Dienst auch jedes Mal neu gestartet, wenn ich eine Änderung vorgenommen habe sudo systemctl restart ssh.service. Das ist jetzt wirklich frustrierend. Eine einfache Einrichtung funktioniert nicht und dauert Stunden.
