 Okay. The measurements in comment:22 look ok to export, even if they get
 accidentally disclosed. I'm thinking it's prudent to keep the IP address
 authentication for port 9100, to mitigate against potential
 vulnerabilities in prometheus-node-exporter itself.

 It's probably better not to modify /etc/init.d/prometheus-node-exporter
 because that will cause a conflict when upgrading. It looks to me like
 /etc/default/prometheus-node-exporter is the right place and is
 sufficient.
