The NTP Pool Needs More Servers — Yours, If Available
Do you have a static IP or two? If so, you might be able to spread some Internet infrastructure well-being with very little effort. An anonymous reader writes "The NTP Pool project is turning 10 soon, and needs more servers to continue serving reasonably accurate time to anyone in the world."
Some quick searching shows one can get a USB GPS receiver for $27 and the comments say it works with linux/gpsd, showing up as /dev/ttyUSB0.
Somebody could make a simple OS image that would narrow the scope of the problem to the availability of ~$60 and an available public IP address.
My God, it's Full of Source!
OUTSIDE_IP=$(dig +short my.ip @outsideip.net)
Until somebody hard codes your server into their commercial firmware and screws up the NTP implementation.
