Is the KVM Console not working cause of damn Java?

Do you get the following “IOException – Authentication Failure!” error when you are just simply trying to connect to your server (CS24-SC) via the built in KVM/Console in BMC? – Turns out this is a really easy fix

 

It turns out you’re just using the wrong version of Java…

You will need to install the 32 bit version of Java. Since the CS24-SC is older hardware, Java updates will likely break your remote access. In the case that you have updated Java or for some reasons the KVM just stopped working, you should roll back your Java version. I have found success with Java 7 Version 55 and 51, I have seen others have success with most other versions of 7, but this is working for me, so why change it. I’ve put a link to the java archive below:

NOTE:Also make sure you are opening your .jnlp file with javaws.exe if you continue to see this error after installing the 32bit version. This may happen if you have both 64bit and 32bit versions installed.
