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.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

Here’s how to fix the issue on the client side:<\/p>\n\n\n\n

jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024<\/p>\n<\/blockquote>\n\n\n\n

Comment it out, copy it, delete the word „MD5“.<\/p>\n\n\n\n
