In case you are a Linux user unsuccessfully trying to connect to your IPMI/LOM Console using IcedTea / OpenJDK 8 or newer, you will likely run into this error.
You know, because if you’re a major hardware vendor selling expensive enterprise class servers, you don’t care about your IPMI hardware once you sold it.
Here’s how to fix the issue on the client side:
Find the java.security file. In my case it is located in /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/java.security
Then find the row
jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024
Comment it out, copy it, delete the word „MD5“.
#jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024 jdk.jar.disabledAlgorithms=MD2, RSA keySize < 1024
