Java IDRAC 6 Ubuntu 18.04 setup

I recently acquired a Dell PowerEdge R610 and had a hard time getting its iDRAC to work properly on my ElementaryOS setup (Ubuntu 18.04 derivative.) I had two problems: Connection failed error and keyboard not working.

Connection Failed

After much searching I finally found this post:

The post explains the problem is with the security settings of Java 8+ preventing the connection. I didn’t know where my security file was so I first ran a quick find command to find it:

sudo find / -name java.security

In my case it was located in /etc/java-11-openjdk/security/java.security

The last step was to remove RC4 from the list of blacklisted ciphers, as this is the cause of the problem.

sudo vim /etc/java-11-openjdk/security/java.security

#change jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024, \ to be:
jdk.tls.disabledAlgorithms=SSLv3, DES, MD5withRSA, DH keySize < 1024, \

Save and exit, and iDRAC will now load!

Except now…

Keyboard doesn’t work

My system was defaulting to using JRE 11, which apparently causes the keyboard to not function at all. I found on this reddit post that you really need an older version of Java. To do so on Ubuntu 18.04 you need to install it along with the icedtea plugin and run update-alternatives

sudo apt install openjdk-8-jre icedtea-8-plugin

Edit /etc/java-8-openjdk/security/java.security and remove the restriction on the RC4 algorhythm. Then configure the system to run java 8:

sudo update-alternatives --config java
#select java 8

Lastly, configure the icedtea plugin to run Java 8 instead of 11, because for some reason this plugin ignores the system java settings. Launch the IcedTea Web Control panel (find it in your system menu) and then Navigate to JVM settings. Enter /usr/ in the section “Set JVM for IcedTea-Web – working best with OpenJDK” section. Then hit Apply / OK

Phew. FINALLY you should be able to use iDRAC 6 on your modern Ubuntu system.

  1. I don’t know if you’ve resolved the issue with iDRAC 6 but if you have enough memory say 8gb ram and a decent processor, I’d run a VM(virtual machine) put an evaluation of Windows 10 pro in it and download java 7 jdk, also read the dell iDRAC 6 manual for a supported version of desired browser ie chrome,Firefox or internet explorer to see exactly which version it supported up to. Please note that iDRAC 6 is retired and anything you do is at your own risk. I use a VM for management, Easier to snapshot if mistakes arise. I have several R10’s and R710’s in my lab setup. Depending on what your server is used for you could consider using bare metal hypervisor to host serval OS’s. Hope this helps sorry if you’ve already solved it.

    1. Having a VM for iDRAC stuff is a route I might go down. I was able to get it to work, but I must run and old version of Java which is indeed not ideal. Thanks for the input!

  2. This is a life saver..
    But the question is, why does the newer version not work with the keyboard?? Is it similar to the network security issue and can be diabled in the java config file..
    I too think its dumb to have to stay with old and likely buggy instance of java on your system..
    a VM looks like a resonable path, but my got thats a lot of disk and hard work to run a simple tool.

    There are so many Dell R610/710 units in the wold now, it would be great if there wa sa simply tool to run to do this console requirements..

    DELL!!!!!! as I slam my fisk into the table…

    1. Haha I have no idea why it does that. Maybe weird incompatibility with that version of Java? I’m glad this was helpful!
