Pinned topic java application blocked vnc.VncViewer

‏2014-03-19T21:24:47Z |

I am at a loss trying to fight this so am looking for some help.

Ever since I updated my MM to the latest code, I can no longer Remote Control any of my blades. I have tested this using two separate BldeCenter chassis along with XP, win7 in various flavors. Nothing works and I keep getting the Application Blocked errors.

 

I have completely deleted my java installs and re-installed from scratch the very latest version yet same problem.

    Finally... a solution!!!

    This weak security is rejected by default on new versions of java.

    The solution is to edit the java.security file and comment out the following line

    jdk.certpath.disabledAlgorithms=MD2

     

    Works perfectly so long as you're not worried about java security on that particular win machine.

    Hi,

    Go to your All programs/Java/Configure Java

    Select Security tab

    Under Exception Site list -

    Add the ip addresses of your AMM.

    That was one of the first things I did, to completely lower and turn off java security. Does not work.

    Also, IP cannot be entered but http://10.0.0.30/ for example can be, which I have.

    Always;

    Failed to validate certificate. The application will not be executed

    vnc.VncViewer

    Failed to validate certificate. The application will not be executed

    com.ibm.asm.remotedisk.RemoteDisk

     

    I also cleared out all certs in both ie and firefox, no good.

    Made sure all certs are cleared in java, no good.

    Have you changed/lowered your browser security settings?  Either try adding the Java certs to the exception list or the MM IP addresses?  I don't have any MMs so I can't test it, but I've had to do similar for the AMMs when using FireFox.

    Josh, are you the only person left on the IBM forums??? LOL

     

    Yes, I've done all of that, lowering security to nothing, clearing out all certs, adding exceptions, you name it. What ever I've not done yet is probably the answer.

    I also started wondering about drivers, this only began once I upgraded the MM software on both chassis.

    Just a thought.....

    If you check the Release Notes, find the minimum level that supports the blades you need in question and flash it to that level, will you see the same Java errors?

    It's something to try.
