iDRAC (Sun) Java console not working from Linux

Question

Hi,

I'm trying to use the iDRAC6 (version 1.50) Java console for a Dell R815 server, but it does not work with the Sun JRE (java6), on my Linux Ubuntu 10.04 64-bit system, using Firefox 3.6.10. When I click on the "Launch" button, I can see the Sun Java Web Start logo, but after a while I get the error reported below [1].

However, I managed to run the remote console by installing the openjdk JRE and its browser plugin, and explicitly selecting the openjdk javaws when launching the Java console.

Is there a way to let the Sun JRE work with iDRAC ?

Thanks, regards.

I have the exact same problem except on an R710. Windows7 using Mozilla 3.6.13

If I remember correctly, the DRAC wants Java 6 Update 11.  Give that version a shot and see what it does?  Also you can just switch to ActiveX aka Native mode.

Yup, use the latest Sun's JRE (or IcedTea 1.0.2 and above). BTW: Is there a chance that Dell will fix the issue with Chrome? (you cannot open a console with Chrome and the Java plugin).

Hi, I encountered the same thing with Ubuntu 10.10 64-bit with Firefox 3.6.22 and here's how I got it to work. YMMV.

Install Sun's version of Java. Good instructions here: https://help.ubuntu.com/community/Java

To make sure your system is configured for Sun Java:

sudo update-alternatives --config java

Then select the number for java-6-sun.

In the location bar of Firefox: about:plugins

Determine which version of Sun Java Plugin you have installed.

If it says "IcedTea NPR Browser Plugin...", then remove this plugin from the browser or remove it entirely with Synaptic.

Restart Firefox.

Firefox should be able to find the new version of Java and install the appropriate plugin. If not, then you may need to install it manually.

If so, you may see "Java(TM) Plug-in 1.6.0_26" in about:plugins.

Now try to use the DRAC virtual console in.

If you still can't, you may need to manually copy some Firefox DRAC plugin files.

There's a good tutorial here: http://techblog.roethof.net/dell-drac5-and-firefox-on-linux/

Try to use the DRAC virtual console again.
