Ich habe ein Problem, mich per SSH mit einem Server zu verbinden. Authetifizierung soll über einen RSA-Schlüssel laufen.
Ich habe per ssh-keygen -t rsa einen Schlüssel erstellt, dabei den Default-Speicherort belassen und ein Passwort angegeben. Den öffentlichen Schlüssel habe ich dann dem Kunden geschickt, der diesen - davon gehe ich bisher aus - korrekt für dem sshd des Servers hinterlegt hat.
Wenn ich mich jetzt mit dem Server Verbinde, erhalte ich folgende Ausgabe:
