Hello !
I come here because i have to install an NTP client software on a
windows PC (I've already have a server which run under Linux) . I
would like to do a software on Labwindows/CVI which save the value of
the Transmit Timestamps, the delay and the offset...
I see two solutions to do that:

Thanks for the answer Heiko, and you're right it's Vivien.

I have some trouble setting up a Brandywine Communications PCI-
SyncClock32Univ as a reference clock in a Linux computer.
refclock_gpsvme.c seems to support the Brandywine Communications PCI-
SyncClock32Univ. The memory map in struct psc_regs do match.

I've just intalled this new version...and suddently my ntpd doesn't
work anymore
Windows told me that : "ntpd.exe have detected a problem and have been
closed" (translation from spanish).
What could have happened ?
I tried to reinstaller an earlier version : [EMAIL PROTECTE
hat the error message, sorry...
I've just reinstalled the earlier version : [EMAIL PROTECTED]
o-win32-setup. It works and i'm fine with that.

Vivien

Hello,
Has anybody been able to make the orphan mode work with manycast
clients/servers?
I am new to NTP and have seen some rather contradicting information on
this on Internet.
Thanks in advance.

My ntpd produce two types of stat files : peerstats and rawstats...
I know what each field is for each file but the question is for each
execution of the ntpd, the peerstats receive three lines and the
rawstats four...

Hello,
I would like to edit my ntp.conf file to make it easier to administer.
Currently my ntp.conf contains:

It seems sensible to change this to:

or to:

My NTP server is run at the local phone company. They already have a
GPS fed stratum 2 (?) time source fed via GPS on the roof. The CO guy
told me that they have lots of leads off their "composite clock" and
we could have one if we needed. Apparently this timing source feds all

Is there a way to log each request from a client to a file? I'd like
to keep a running log of whenever someone requests time from me. Then
I can graph over time if usage has gone up or down using MRTG or
something. Is this possible?

Is this supported or possible in Windows 2000?
I've managed to edit the registry to point at my local NTP server and
this works fine. The NTP host supports MD5 authentication and,
ideally, I'd like the Windows 2000 client to use this when requesting
from the NTP server.

I'm doing NTP exchanges to determine my clock offset. I use this to
adjust my clock frequency, but there's a lot of lag so I overshoot by
too much and it oscillates around the reference frequency. This is an
audio clock so I have to do my own NTP stuff. I think I want to use a
phase lock loop as de

Just that changes I make to correct for frequency offset take a while
to fully take effect. If I detect that my current frequency is off by
5 Hz, I reduce my frequency by 5 Hz, but in 2 seconds when I do my
next NTP packet exchange, I see that I'm now off by say
> Are you interested in time as well as frequency, or just frequency?
Just frequency. This frequency controls a counter. I use a more
traditional NTP-sync'd time (which is accurate to a few PPM) to map
that counter value to an absolute time (e.g at counter X, the NTP time
is Y). Then I do NTP pack

When I do an NTP exchange of timestamps, I take the resulting

I implemented a PID in software and after a little experimenting with
the gain parameters, I'm able to get and maintain sync. There is a
