Ich habe gerade meine AWS Deep Learning-Instanz eingerichtet und mit einer neuen Schlüsselpaardatei verknüpft, die ich erstellt habe.Amazon ssh-Berechtigung verweigert (öffentlicher Schlüssel) mit Fehlermeldung
aber wenn ich versuche, mit folgendem Befehl ssh:
ssh -v -i /Users/username/aws-deep-learning-ami.pem [email protected]_IP.compute.amazonaws.com
erhalte ich die ziemlich lange Fehlermeldung: Zugriff verweigert (öffentlicher Schlüssel).
die Details mit -v Drucken zeigt dies:

Das bedeutet nur, dass die Anmeldeinformationen nicht funktionieren - falsche Anmeldeinformationen, falscher Benutzer, was auch immer. Das ist nicht wirklich eine Programmierfrage, vielleicht besser bei [su] oder [sf] – pvg
Danke für die schnelle Antwort! Sollte ich für jedes Schlüsselpaar einen anderen Benutzer verwenden? – user3642173
Versuchen Sie stattdessen den Benutzer ec2-user. – stdunbar
