Ich versuche, einen öffentlichen Schlüssel auf einen Remote-Server zu kopieren. Ich bin lokal als [localname] angemeldet und der Schlüssel befindet sich lokal unter ~/.ssh/. Ich bin auch per SSH als [remotename] bei [remote.com] angemeldet und versuche, den Schlüssel folgendermaßen hochzuladen:
scp [localname]@localhost:~/.ssh/id_rsa.pub [remotename]@[remote.com]:/home/[remotename]/.ssh/uploaded_key.pub
Ich sehe die Willkommensnachricht für [remote.com], aber dann werde ich gefragt:
[localuser]@localhost's password:
Aber das Passwort von [localuser] (das, mit dem sich [localuser] beim lokalen Computer anmeldet) wird nicht akzeptiert:

Hier ist die ausführliche Ausgabe:

Kann jemand bestätigen, dass dies die richtige Verwendung von scp ist, oder Tipps zur Fehlerbehebung geben?

Antwort1
Das scheint zu kompliziert. Versuchen Sie es mit dem Folgenden von localhost:
scp ~/.ssh/id_rsa.pub [remotename]@[remote.com]:.ssh/uploaded_key.pub
Antwort2
Interessante Frage, ich habe gerade das Gleiche versucht und bin auf den gleichen Fehler gestoßen. Ich habe -vvvswitch verwendet, um herauszufinden, was unter der Haube vor sich geht, und im Grunde wird per SSH auf Ihren lokalen Host zugegriffen und ausgeführtscp -v ~/.ssh/id_rsa.pub remoteuser@remoteserver:~/
Das sollte jedoch problemlos funktionieren.der Befehl versucht, das Kennwort von der Standardeingabe zu lesen, aber ohne steuerndes TTY gibt es kein Kennwort und daher die Meldung „Zugriff verweigert“.
Hier ist eine gekürzte Version des Debuggens, die meinen Standpunkt erklärt:
debug3: authmethod_lookup password
debug3: remaining preferred: ,password
debug3: authmethod_is_enabled password
debug1: Next authentication method: password
dpac@localhost's password:
debug3: packet_send2: adding 64 (len 60 padlen 4 extra_pad 64)
debug2: we sent a password packet, wait for reply
debug1: Authentication succeeded (password).

Ich habe bisher keine Version gefunden scp, die die Verwendung der „Remote“-Spezifikation für Quelle UND Ziel unterstützt.
