We run some dell servers that have idrac cards in them. Some of the older ones have older v6 cards in them. Connecting to these via a mac has been a bit of a bear lately with all the java changes. Doing a bit of research and using the terminal, I found a way to connect to these.
The way that I found was to manually call javaws from the command line specifying which version I wanted to run. Since it seems that the only issue is with java > 1.6, you can just call the java 1.6 javaws. I got the idea from reading this post.
In terminal I found the javaws in my path. It was located in /usr/bin. I checked to see what that was symlinked to. It ended up in a ‘versions’ directory that had many different versions. I created my own symlink in /usr/bin pointing to the v1.6.0 path vs the current path. Once I did this, I had a 1.6.0 version of javaws in my path, aptly named javaws-1.6.0.
When you are logged into the drac, using safari, you can click on the launch virtual console button. This will download a .jnlp file. I didnt write a script or anything, but just found the .jnlp file in the finder via the download window in safari, moved it to the desktop and then in terminal ran javaws-1.6.0 filename.jnlp. This fired it up correctly.
For reference, these are the two versions of javaws I have linked:
/usr/bin/javaws -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/javaws
/usr/bin/javaws-1.6.0 -> /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Commands/javaws
My pain in the bean, your glean.
