Connecting to remote console on Dell iDRAC on R815 fails

  • 772

The iDRAC's virtual console uses jnlp.

I have installed:

sudo apt-get install icedtea-netx

Connecting to the iDRAC's webserver works using Firefox. When I click 'Launch Virtual Console' it starts the java app. The JVM then asks for a few permissions which I grant (the certificate is selfsigned). But it then fails with: "Connection failed".

I had this working when running Ubuntu 18.04, but it broke after upgrading the client to Ubuntu 20.04.

What am I missing?

drac dell-poweredge ubuntu-20.04

    iDRAC uses RC4 which is now considered insecure.

    It is disabled in:

    /usr/lib/jvm/java-11-openjdk-amd64/conf/security/java.security

    Remove RC4 from:

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

    And then it works.
