Dell RAC – Error when reading from SSL socket connection

You may find when trying to connect to the DRAC console, you might see an error – “Error when reading from ssl socket connection”

This of course, always happens at the worst possible time when you really need to connect to the RAC.

drac ssl error

In Control Panel > Java > Security:

  1. Check “Enable java content in the browser”
  2. Set security level to “High”
  3. Add each DRAC IP to exception list
  4. In C:\Program Files (x86)\Java\jre1.8.0_91\lib\security\java.security, comment this line out:
    • jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024
  5. In C:\Program Files (x86)\Java\jre1.8.0_91\lib\security\java.security, comment this line out:
    • jdk.tls.disabledAlgorithms=DH keySize < 768

As soon as I made those changes, I was able to connect, and rescue the server I was working on.
