Supermicro KVM over IP

Supermicro's old KVM over IP machines rely on Java Web Start. When you log into the KVM web interface, you can't actually view the console until after you have downloaded the .jnlp file that has the appropriate KVM UI available via a JAR.

If you have the JAR, you can launch it, but if you only have the .jnlp file, the easiest way is to use the IcedTea runtime to get it going.

On Ubuntu 22.04 LTS you can get this with:

sudo apt install icedtea-netx

And then starting the .jnlp file like so:

javaws launch.jnlp
