PowerProtect: Data Domain-registrering mislykkes, og ADS0005 angiver SSL-handshake-fejl

PowerProtect-grænsefladen viser, at Data Domain-certifikatet mangler under "Administration ->Certifikater".  Kommandolinjeværktøjet PowerProtect Data Manager Tool kan også bruges til at validere de tilgængelige certifikater: ppdmtool -listcert

Ikonet /var/log/brs/discovery-service/discovery-service.log viser ADS0005 Advarsel:

Ikonet /var/log/brs/secretsmgr/secret-mgr.log viser en 'SSL-undtagelser':

OpenSSL-forbindelsen til Data Domain viser en SSL handshake Fejl:

The Data Domain adminaccess Kommandolinjeværktøj viser, at certifikaterne stadig er gyldige:

The Data Domain /ddr/var/log/debug/sm/sms.info log Viser "no shared cipher" Fejl:

Data Domain og PowerProtect-enheden har ikke en delt kryptering til at fuldføre SSL handshake med succes. 
 
Ikonet adminaccess Kommandolinjeværktøjet kan bruges til at validere Data Domain-cifrene:

sysadmin@datadomain# adminaccess option show cipher-list
Adminaccess option "cipher-list" set to "ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256".

Ikonet /usr/local/brs/lib/secretsmgr/config/application.yml fil kan bruges til at validere PowerProtect-cifrene:

admin@ppdm:~> cat /usr/local/brs/lib/secretsmgr/config/application.yml
myserver:
  ssl:
    enabled-protocols: TLSv1.2,TLSv1.3
    ciphers: |
      TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,
      TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,
      TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,
      TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
    key-alias: secretsmgr
    key-store: "${sm.ssl.keystore-path}/secretsmgr.keystore"
    key-store-provider: SUN
    key-store-type: JKS
    protocol: TLS
    trust-store: "${sm.ssl.keystore-path}/secretsmgr.truststore"
    trust-store-provider: SUN

    client-auth: want
    enabled: true

Føj DHE-pakkerne til Data Domain-krypteringslisten. Eksempel:

adminaccess option set cipher-list DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256
