Ich habe ein Authentifizierungsproblem in Windows Server 2016.
Ich habe einen lokalen Benutzer (keinen Administrator) erstellt, der eine Verbindung per SSH herstellen muss und sich mit seinem privaten Schlüssel authentifiziert.
Da Windows Server 2016 nicht mit der installierbaren OpenSSH-Funktion ausgestattet ist, habe ichdieser Leitfadenund erfolgreich die neueste Version von OpenSSH installiert vonPowerShell-GitHub-Repository. In den Windows Server-Diensten ist „OpenSSH SSH Server“ korrekt ausgeführt und auf automatischen Start eingestellt.
Ich habe außerdem eine spezielle eingehende Regel in der Windows-Firewall mit erweiterter Sicherheit erstellt, um Verbindungen über Port 22 nur von bestimmten IPs aus zuzulassen (tatsächlich funktioniert die Standardauthentifizierung mit Benutzername und Kennwort sowohl in Putty als auch in WinSCP).
Ich habe den öffentlichen Schlüssel des Benutzers in einer Datei „authorized_keys“ im Ordner „.ssh“ im username1Hauptverzeichnis des Benutzers (später „.ssh“ genannt) abgelegt. Ich habe es sowohl manuell (Ordner erstellen und Datei kopieren) als auch mit der WinSCP-Funktion „Öffentlichen Schlüssel auf Server installieren“ versucht. In beiden Fällen ist das Ergebnis dasselbe.
Der Ordner verfügt über Lese- und Schreibberechtigungen sowohl für die Administratoren als auch für den lokalen Benutzer, der sich authentifizieren muss. Der Schlüssel hat das Format „ssh-rsa XXXXXXX rsa-key-YYYYMMDD“.
Zuletzt habe ich den privaten Schlüssel in der Registerkarte SSH -> Authentifizierung in WinSCP eingefügt und versucht, eine Verbindung herzustellen. Ich habe den folgenden Fehler erhalten: „Der Server hat unseren Schlüssel abgelehnt“.
Ich habe sowohl in WinSCP als auch in Putty denselben Fehler erhalten. Ich habe nur zu Testzwecken neue private/öffentliche Schlüssel erstellt und eine Datei „administrators_authorized_keys“ in „C:\ProgramData\ssh“ mit demselben öffentlichen Schlüssel erstellt, aber ich erhalte denselben Fehler. Ich nehme an, dass etwas mit der Dateiberechtigung nicht stimmt.
Ich kann nicht herausfinden, was mir fehlt. Ich habe viele Fragen gelesen, aber sie drehen sich alle um Linux-Instanzen. Kann mir bitte jemand helfen?
Dies ist das WinSCP-Protokoll:

In beiden Protokollen username1ist der lokale Benutzer, der eine Verbindung herstellen muss, username2ein Administrator (nicht SYSTEM).

Antwort1
Ich glaube, diese Botschaft ist ziemlich klar:
3356 2019-12-17 19:31:45.556 debug3: Ungültige Berechtigungen. Versuchen Sie, die Berechtigungen für den Benutzer zu entfernen: VM-EPM\username2 (S-1-5-21-3826319457-1004635287-1909893433-1001) für die Datei C:/Users/username1/.ssh/authorized_keys.
No other user except for the user himself/herself (username1) can have write permissions to the authorized_keys file.
