Just a short blog about accessing the java remote console on DRAC7 using servers from a Fedora client (mostly so I can find this again in a few years and remember what I had to do):

If you just try and launch it, everything goes great until the end, and you get “Connection Refused”. This is of course a completely wrong error message. Really the problem is that it can’t find cacerts. You must:

mkdir -p ~/.java/deployment/security

ln -s /usr/lib/jvm/java-1.7.0-openjdk- ~/.java/deployment/security/trusted.certs

Of course you need to fill in your openjdk version that you have installed. Once you do that, launch the console and it should connect and work fine. 

Many thanks to Patrick Uiterwijk for figuring this out. 🙂
