Fix for Java 8+ & iDRAC 6 Connection Failed

For work I recently had to stand up a temporary system that has the old iDRAC 6 in it. Many will know that Java 8+ (from my testing) seems to have a disliking for that version of iDRAC. I spent a day grumbling at the error while standing next to the offending system in the data center watching the OS hang on install. After doing some digging this morning I found the key that kills the connection. SSLv3.

So thanks to MathieuW on the dell community forums for posting this info!

Go to Java installation folder.
Open {JRE_HOME}\lib\security\java.security -file in text editor.
Delete or comment out the following line “jdk.tls.disabledAlgorithms=SSLv3”.

My notes, open the file in notepad++ as admin, just comment out the whole line. Save. Re-Launch your virtual console.

    Fantastic, thankyou so much!!!! I’ve been trying for ages to get the virtual console to work since java was updated to 8! Life saver.

    Thank you so much have been keeping V8 162 on my machine for a while and not updating Java because of this issue. I was hoping that V8 191 would have solved the issue. NOT the case.

    You can get Java 8 191 to connect.

    Its a horrible recommendation but you it will connect if you remove all the disabledAlgorithms.

    C:\Program Files\Java\jre\lib\security\java.security
    C:\Program Files (x86)\Java\jre\lib\security\java.security

    # jdk.certpath.disabledAlgorithms=MD2, MD5, SHA1 jdkCA & usage TLSServer, \
    # RSA keySize < 1024, DSA keySize < 1024, EC keySize < 224

    # jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024, \
    # EC keySize < 224, 3DES_EDE_CBC

    # jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024, DSA keySize < 1024
