As I understand it, it is free to download. It doesn't include the source to
the driver or library because they are built on a licensed tool but the example
program code should be there and there is a whole library available for you to
code your application against.

Does open source ntpd support using IPv6 link local addresses for
client/server/peer modes? I have not been able to use link local addresses to
peer 2 servers on the same subnet.
Thanks...Greg

Can I set the value of flag1 for a reference clock driver using ntpq? I'd like
to toggle some behavior back and forth without restarting ntpd.

Wow, that is an old piece of equipment. I may be able to find
something. One of my first jobs at Datum was to add the SNMP and NTP
HMAC options to the TS2000. It is an old PC based design using Ampro
modules. If I can't find the manual, do you have a specific ??.
-Original Message-
No, this was the replacement to the TS2000. Completely different
cpu/os/codebase. And it came out in 1996 which just goes to show how
old that TS2000 is.

In CDMA, the time that you see displayed on your phone is a data
service, not necessarily related to the GPS timebase directly pulled
from the TDM layer.

The normal method, and the cleanest, is to provide a reference clock
driver and let ntp keep the kernel clock synchronized to the card
timebase. If you are bound and determined to make your own code, the
place to start is in configure to specify your clock model and then
systime.c in libntp. Be
I see this has an event capture input. Has anyone tried using this vs
bringing in the pps to see if they can lower the jitter on interrupt
handler?

I think it is the original rfc1305 (NTPv3) language that determined that
the bits only show up on the day of the event. While the actual
requirement is merely that they are set before 23:59 and cleared after
midnight, the supporting text is shown below.

I'm not quite sure what you mean. A reference clock doesn't compute an
offset, it acquires, formats and returns a time value from an external
source. NTP takes care of the rest.

Aah. Good point Dave. I remember that USRobotics Sportster external
modems had dip switches. That was always an issue for us as the
switches took precedence over software commands. Maybe that's the case
here John?

To be clear, I am not part of the support organization, or even the test
and measurement division which manufactures these products anymore but I
have a long history of assocation with them.

to distribute. Turns out that no matter what I say, there is quite a
lot of legal precedent stating implicit support with any corporate
sponsored distribution. I know that the world is changing but legal
departments are very conservative by design.

with multiple network load generators connected through and across

developed a healthy respect for many of the various sampling and

Are you sure the clock wasn't set in between? Is this a one-time or a
consistent state? What mode packet is this, mode 3 or 4? And why do
you say they are only a few seconds apart? The receive timestamp is the
time the request was received by the server if in a mode 4 packet. In a
mode 3, it
