Su funktioniert nicht

Ich installiere einen OrangePi (leistungsstärker als der Rasp). Nach der Installation des Systems mit dem Standardbenutzer root möchte ich einen neuen Benutzer hinzufügen und eine Verbindung von ssh herstellen

adduser foobar

Ich habe alle Dateien erstellt /home/foobar

Ich kann den Benutzer aber nicht wechseln

# su foobar
#

Auch wenn ich versuche, mich von ssh anzuschließen

ssh foobar@ip

Die Verbindung schließt gleich danach.

Wenn ich ssh -v -v -v foobar@ip

und

Irgendeine Idee ?

Wenn deine Aufforderung tatsächlich ist # Wie in dem Beispiel, das Sie gezeigt haben, sind Sie bereits root.

— gronostaj

Tun /bin/bash und /bin/zsh existieren?

— Paul

Ich möchte nicht root sein. Ich möchte mein Benutzer sein. Ich kann mich nicht als Benutzer mit ssh oder mit der guten alten Tastatur am Anmeldebildschirm anmelden. @Paul ja bash und zsh existieren.

— Ragnar

Welche Linux-Distribution hast du installiert?

— Paul

Ich installiere Raspbian

— Ragnar

Entschuldigung für die Antwort, nicht das Kommentieren. Die Situation, die Sie angezeigt haben, ist auf Benutzer zurückzuführen foobar hat keine Standard-Shell.

Um es zu überprüfen, versuchen Sie es auszuführen su diesen Weg: su -s /bin/bash foobar als Wurzel

Ob foobar@pi und das Dollarzeichen erscheint, dann ist meine Antwort richtig.

Vielen Dank für Ihre Antwort, aber wie ich im Kommentar meiner Fragen gesagt habe: Der Benutzer, den ich erstellt habe, hat eine Standard-Shell: /etc/passwd gil:x:1002:1006:Gil,,,:/home/gil:/bin/zsh Ich habe eine neue mit bash als Standard erstellt. Ich kann mich auch nicht einloggen. Ihr Befehl funktioniert auch nicht. Aber danke.

— Ragnar

Su funktioniert nicht - Raspbian
