Ich habe eine Verbindung zu einem Dienst mit Client-Authentifizierung schwer. Der Dienst ("SecureService") ist auf AWS. Die Clients befinden sich auf einer Linux-VM auf meinem Mac. Nginx auf SecureService erzwingt die Client-Authentifizierung für die Ressource, auf die ich über Port 443 zugreife. Ich kann eine erfolgreiche Antwort von derselben VM auf denselben SecureService erhalten, indem ich eine eigenständige Java-Standalone-Anwendung (openjdk 1.8.0_60) oder andere Clients verwendet (wget, openssl), aber nicht von demselben Java-Code, der auf Websphere AS gehostet wird (wobei er sich auf ältere Bibliotheken und IBM J9 VM, Build 2.6, JRE 1.6.0 verlässt). Bei der Neuzuordnung des SecureService-Hostnamens zu 127.0.0.1 in/etc/hosts wird derselbe Java-Code für Websphere AS erfolgreich mit einem lokalen openSSL-Server verbunden, der eine Clientauthentifizierung von derselben Zertifizierungsstelle erfordert. Die Antwort von SecureServer in der fehlgeschlagenen Verbindung meldet "400 Kein erforderliches SSL-Zertifikat wurde gesendet" ... "400 Ungültige Anforderung", aber tcpdump Paket-Captures zeigen, dass es KEINE Zertifikatsanforderung sendet, während es in allen anderen Fällen ist. Das ist rätselhaft und führt mich zu der Annahme, dass die ClientHallo-Nachricht etwas enthält, was der Server nicht mag, obwohl ClientHello-Nachrichten bei erfolgreichen und fehlerhaften Verbindungen sehr ähnlich sind.SSL-Verbindung fehlgeschlagen mit keine Zertifikatsanforderung vom Server, Verbindung zu Nginx auf AWS von einer lokalen Websphere AS unter Java 6
Ein ziemlich seltsames Detail ist auch, dass tcpdump nie das erste TCP-SYN-Paket von meinem Client auf den Server in der fehlerhaften Kommunikation erfasst, während es den Rest erfasst (SYN + ACK vom Server, dann ACK vom Client) und alle Pakete (SYN, SYN + ACK, ACK) auf allen anderen Kommunikationen.
Alle Kommunikation verwenden TLSv1.2 in allen ihren Teilen.
