It should be a huge embarrasment to the designers. They survive on low price
and unique features. It would be quite amazing to have a CLI
I've responded in bits and pieces to this thread and haven't done an
excellent job expressing my overall opinion. This is probably because my
initial goal was to point out that GPS-transmitted time is no less subject
to being attacked than your garden variety NTP-transmitted time. Since this

Yeah, that's a reasonable course of action for most networks.
For most data centers with time sensitive transactions, at least.
*sigh*
Forrest,
I think you’re gilding the lilly. My original recommendation was to use GPS as
primary, for its superior accuracy and resistance to attack, and have anti-GPS
back up. If you want automatic fail over, do that in an intermediate server on
your site that makes a conscious test and

We're going to have to somewhat disagree here...
I may not have been 100% clear about what I see as the most common risks
for GPS. The reason I suggest that NTP risks and GPS risks are similar is
not primarily due to intentional time injection hacks (although that is a
risk). Instead, it's
Replying to two posts at once...
One can definitely get inexpensive and high-quality rubidiums for dirt
cheap on the second-hand market. I've specifically ignored those when
discussing price as options as one can never be sure about their accuracy
or long-term reliability, and I try to filter
Hi group!
Not sure if this is even allowed but worth a shot;
Does anyone/is anyone an engineer with Frontier in Connecticut?
I have some questions regarding their FTTH/FTTB products, and their wonderful
tier 1 support is useless and has been for the last month of me paying for this
service.

There are lots of ways to improve a GPS-based NTP server. Better antenna
positioning. Better GPS chipset. Paying attention to antenna patterns.
Adding notch filters to the GPS feed. And so on.
They are not a very meaningful improvement.
But, in
Forrest seems to have posted a good general overview and perspectives about
"good enough for the use case" while others continue to be pedantic about
nuances that don't seem to be relevant to most use cases.
