[Beowulf] Intel motherboard BMC

This sounds so much like a common JavaScript problem. I thought this might
be valuable here:
https://www.gnu.org/software/freeipmi/freeipmi-hostrange.txt
When test a JavaScript file the browser will shortcut to running the file
not the browser itself via a "server" resulting in s omething like this:
///localhost/3000/myNewApp
For what it's worth.
All meaning according to the rest of your shop the cluster is dead.
