So this has popped up a few times now and as I kept forgetting which bit to disable I figured I’d make a note!
I have the joy of still supporting a number of systems with older DRACs. These really don’t like current versions of Java – oh and good luck getting the ActiveX options working in newer versions of IE! Logging on to a DRAC5 this morning and needing to get to the remote console the below message decides to pop up when loading the Java App –
To fix this you’ll need to follow the below steps:
Update – Looks like a few more protocols have now been killed off so having tried to connect to an old DRAC again this morning (19/07/16) there’s some additional items to remove:
1. Open up Notepad or Notepad++ (make sure it’s in Administrator mode)
2. Browse to your Java install, most likely C:\Program Files (x86)\Java\jre1.version\lib\security
3. In this directory open the java.security file
4. Look for the string jdk.tls.disabledAlgorithms=
5. Remove the SSLv3, RC4 and MD5withRSA text or simply add a # to the front of the line disabling it completely.
6. Look for the string jdk.certpath.disabledAlgorithms=
7. Remove the MD5 text or again simply add a # to the front of the line disabling it completely.
8. Save the file and enjoy being able to use DRACs again!
As a side note this is of course a security measure that the newer versions of Java have implemented so please consider the risk before disabling.
