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.
