Hi all,
This is my first post from just joining the mailinglist. I apologize
for starting a new thread, but I didn't see a way to reply to a
pre-existing thread. A number of comments were made about Cuckoo, which
is our new product (http://airchitex.com/cuckoo.html). I'd like to have
a chance to respond.
* It's very expensive.
I won't argue that you can make your own time server for cheaper. If
you've got a PC gathering dust in a closet already, you can make your
own NTP server with Linux distributions theoretically for free, or maybe
for the cost of a GPS receiver and antenna. The point is that you have
to have the skill, time and patience to do that. What we are trying to
do is bring a device that requires no setup, and very little if any
configuration and maintenance. If you have the ability to do this
yourself, please feel free. There are a number of reasons that you may
want your own time server. If you want one and you don't want the
hassle of setting it up yourself, we provide an option. Note that we're
nowhere near as expensive as a standalone *NTP* server. But we aren't a
full fledged NTP server, and are attempting to fill the niche below that
for small- to mid-sized businesses that can't afford or don't need a
complete NTP server.
* It's only SNTP.
Yes, that's correct. Nowhere do we imply that we are NTP. We do use
the NTP *protocol*, because there is no such thing as an SNTP-specific
protocol. A client cannot tell the different between an NTP server or
SNTP server, and vice versa.
* The charts on the FAQ page are deliberately misleading.
They're not intended to be, but they are intended to show that if you're
using an SNTP client that relies on a single snapshot (like the Windows
default implementation), latencies from off-network servers can be
suprisingly inaccurate. The text surrounding the chart does point these
differences out, but also points out that NTP will correct for them.
* Is it really a scale of 2000 to -500 ms on the chart?
Unbelievably, yes. That represents the local clock's drift as well as
some outliers on the NTP request latencies.
I'm certainly not trying to be argumentative here, just trying to clear
up some comments. If you have other questions, I'd be happy to answer them.
