Thanks Josh,

it took me a while to find a timeslot (and the java.security file) to try this out, but it worked for my as well.

For macOS users: the file path is /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/lib/security/java.security

All,
To follow up on this, I've had a couple messages sent to me and I've confirmed this my self that there is only a single item to remove from your java.security file to retain the IDRAC6 functionality.

*jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 1024, \*
*    EC keySize < 224, DES40_CBC, RC4_40*, 3DES_EDE_CBC
*

*jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 1024, \*
*    EC keySize < 224, DES40_CBC, RC4_40*

*Effectively it's only `3DES_EDE_CBC` instance should be removed from this directive and nothing more.*


Additionally i would reccommend you make the following change in the IDRAC webpage: iDRAC Settings --> Network/Security --> Services:  Change the SSL Encryption to 256-bit or higher. This doesn't negate the above change thats needed in your java.security file until Dell makes a Fix.

(Thanks to Ivan & Libor for the notes)

    Same problem with IDRAC6, 7, and 8 with latest Java.  Upgrade to
    IDRAC 7&8 fixes it for them, but IDRAC 6 still doesnt' work.

    Work around is to disable some of the security settings for JAVA
    in your java.security file:

    I commented out the following lines:
    #jdk.certpath.disabledAlgorithms=MD2, MD5, SHA1 jdkCA & usage
    TLSServer, \
    #    RSA keySize < 1024, DSA keySize < 1024, EC keySize < 224

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

    #jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize <
    1024, \
    #    EC keySize < 224, DES40_CBC, RC4_40, 3DES_EDE_CBC

    #jdk.tls.legacyAlgorithms= \
    #        K_NULL, C_NULL, M_NULL, \
    #        DH_anon, ECDH_anon, \
    #        RC4_128, RC4_40, DES_CBC, DES40_CBC, \
    #        3DES_EDE_CBC

    Everything worked perfectly after words.  Keep in mind though,
    this does lower your security of JRE, use at your own risk.

        Subject: [Linux-PowerEdge] iDRAC 6 enterprise console not
        working with
                newest java
        Message-ID: <[email protected]

        Hello,

        after updating from Java 8/162 to 8/171 I can't connect to the
        console
        using the Virutual Console Client (i.e, by opening the downloaded
        viewer.jnlp).

        The screenshot shows the "Connection failed." message I got.

        I this on tested this in various combinations, with two R610
        as iDRAC
        "server", and connecting to the them from windows and macos
        systems.
        Finally I found a macbook with an older Java and there it
        still works.


        Any known cure? Otherwise it would be a service call since my
        machines
        are in ProSupport.


        Thanks in advance,
        Peter
