[ntp:questions] New ntp Server

[Mark C. Stephens]

Hi All, I am about to build a new NTP server for testing refclocks.

I believe that BSD is recommended over Linux, which is recommended over Windows?

Which is the *best* OS for an NTP server?

Secondly, I picked up a server out of the Junk pile today, it an HP Dl145G2.

Please advise What I should set the following BIOS settings:
Disable Jitter Bit - enable/disable Function 2 register 94 bit 15
Enable Multimedia Timer enable/disable


Many thanks,
Mark

Windows is so bad for this job, I'd almost say it's broken.

Between BSD and Linux, it used to be that BSD was the winner for
precision timekeeping but new recent Linux comes with PPS in the
kernaland a nanosecond clock and is equal or BSD.But I suspect
many will say that BSD is still the more conservative option, it
changes slower and typically comes with less "stuff".Id go with
BSD unless you intend to do anything else with the computer

BTW dumpster servers are NOT economical unless you have free electric
power.   They will burn up well more then $200 or power a year.   That
is $1,000 over a reasonable life. Look around and buy main board
that uses the single core Atom CPU.  Look for one that does NOT have a
fan on the heat sink.  No fan is a good clue that the CPU uses very
little power  Intal makes one that was a REAL serial port.  That is
the #1 thing you must have.   You can find a main bard with CPU
soldered to it for about $80.  It will pay for itself in very short
time.

Choose the OS which:

a) Provides the development environment you want / need for ref-clock
testing

b) Provides an acceptable level of performance on your hardware

c) Is reasonably maintainable for _you_

Between Linux and BSD I do not think there is much difference. But both
are far better than windows.

Yes, it is a computer, and a pretty good one at that. What is the

Nothing except that he wrote down an incomprehensible line of numbers
and expected people to know that was a computer, rather than a
printer, or an atomic clock.

You were expecting maybe an HP 4972A?-) (10 Mbit/s Ethernet network
analyzer from *many* years ago) or perhaps an HP P/N 19511-80014?-)

No idea. I am afraid that I am not familiar with the arcana of HP model
numberings at all, as I suspect most readers here are not, which is why
telling us that what he refered to was a computer would have been
helpful.

Though he did say "server" and perhaps I'm behind on what that might
imply, but a server is either a computer or someone who brings you
food.  The existence of 'Lunch The HP Way" (*) notwithstanding, it would
seem that HP would be unlikely to make people/things which bring one
food :)

Re: [ntp:questions] New ntp Server

[Mark C. Stephens]

Oh no I am quite happy with my hp3325A ;)


Well Okay, after a slight detour trying to get ilo100 to work, I loaded centos 
6.0 x64 on the DL165 G2 (computer) and found it has 3.3V PCI slots. So none of 
my Serial I/O cards fit, being 5V. I have seen people take a dremel to them to 
cut a 3.3V notch, but I am not a 100% sure this works. 

Centos 6.0 is really impressive I have to say. Also the PPS kernel module is 
already built and installed, just need to load it.

So the plan now is to connect a HP58534A GPS Timing Antenna to the only serial 
port and compare the difference.

On a windows box with the same antenna, I get offset of 0.010 and jitter 0.001 
off the PPS, and ~0.020 offset on the NMEA.
 I think I will try to split the output of the GPS timing antenna into both the 
windows and Linux boxen to compare accuracy on the different O/S's. 

I'll let you know how it goes!

Not sure what you mean when you say you get offset of .010 (I assume the
units a ms, not sec) Ie, what are you using to determine the offset? 
For nmea and offset of .02 sec is not unreasonable, so maybe you are

Hello Sir Unrah,


I just use ntpq -p. I am using Dave Harts rather excellent port to windows:

C:\Program Files\NTP\bin>ntpq -p
 remote refid   st  t   whenpoll
reach   delay   offset   jitter
==
*GPS_NMEA(1).GPS.0   l  1   16  
377 0.000   -0.139  0.059
oPPS(1) .PPS.   0l   -  
16  377 0.000   -0.007  0.002

I restarted ntpd a couple of hours ago so these number will improve.

That is a good question, are we talking seconds for offset and jitter here?

The kernel includes general PPS support, but there is no support for
PPS on serial devices (pps_ldisc module). You'll probably need to use
a newer version of kernel or backport the module to the old version.
You'll also need to recompile the ntp package with the timepps.h
header.

It might be easier to try a newer distro. For instance, Fedora 14 and
later have kernel, ntp and chrony packages compiled with PPS support
and it should work out of the box, even with SELinux enabled :).

They are milliseconds. If ntpd on Windows can really keep the clock
stable to to ~10 microseconds, the recent suggestion posted here to
never use Windows for serious timekeeping might need to be revisited.

It can, with the stars aligned properly.  It's far from assured.  The
best results come from WS2003/WinXP and earlier versions of Windows,
where the Windows port of ntpd is nearly always able to interpolate a
high-precision clock from the combination of the stepping system clock
(10-15ms tick) and the so-called performance counter.  The challenge
is adaptively aligning the two counters, and the scheme currently used
breaks down with Vista and later due to being unable to schedule
sampling of the correlation at a multiple of the clock rate: typically
the clock ticks every 0.5 or 1 msec yet scheduling is limited to 1
msec precision.  With a little luck, ntpd automatically uses the
native windows clock directly (typically showing precision=-10), but
setting NTPD_USE_SYSTEM_CLOCK to any value in the system environment
variables might be useful to force the correct choice with ntpd 4.2.7.

Once you have a system where ntpd interpolation works well, the next
challenge is PPSAPI.  The windows port can use PPSAPI provider DLLs
and includes sample skeleton source code.  So far the only such DLL is
paired with a lightly tweaked Windows serial.sys known as
serialpps.sys.  Search for serialpps-ppsapi-provider to find it and
decide if you're willing to install unsigned driver code that claims
to timestamp DCD.

The results are worse than FreeBSD or Linux  I suspect the difference
is mostly due to the interpolation code having to guess at when, on
the counter timescale, the system clock ticked up to the present
value.  Some ugly busy-looping logic might help refine that and also
overcome the incompatibility with newer Windows versions' clocks.

Here's what I see on my Windows PCs:

 http://www.satsignal.eu/mrtg/performance_ntp.php

PCs Feenix, Stamsund, Alta and Bacchus have PPS sources.  For the best one 
(Feenix, which runs XP), I would only claim "a couple of hundred 
microseconds".  The PC Pixie at the top of that page is an Intel Atom 
system running FreeBSD 8.0.


For many purposes, with one millisecond is quite adequate, for other 
purpose, it's not.

It's a pity the system doesn't provide a function for precise clock
reading.

What resolution has the clock frequency adjustment? I'm reading
about the SetSystemTimeAdjustment function and the adjustment is in
100-ns units applied over an lpTimeIncrement interval. If the interval
is too short I suspect this could also limit the time and frequency
accuracy of the system clock.

Clock interrupt period 15.600 msec (startup slew 19.5 usec/period)
Windows clock precision 1.001 msec, min. slew 6.410 ppm/s

That's from typical ntpd startup on Vista and later.
SetSystemTimeAdjustment operates here in 100ns units per 15.600 msec
fictional tick.  The result is a unit adjustment to the
SetSystemTimeAdjustment argument results in a 6.4 PPM rate change.
sys_residual carry allows finer adjustments over multiple seconds.

I just tried Fedora 16, its quite full of bugs from Anaconda to gnome and 
everything in between!

I understand the political reasons for making the full kernel source so 
obfuscated to install but I wish they would have some mercy on us guys out in 
userland.

I may end up installing something like slackware because it doesn't go off the 
beaten path like the RH based distros.


Amazing

The kernel includes general PPS support, but there is no support for PPS on 
serial devices (pps_ldisc module). You'll probably need to use a newer version 
of kernel or backport the module to the old version.
You'll also need to recompile the ntp package with the timepps.h header.

It might be easier to try a newer distro. For instance, Fedora 14 and later 
have kernel, ntp and chrony packages compiled with PPS support and it should 
work out of the box, even with SELinux enabled :).

Re: [ntp:questions] New ntp Server

[Mark C. Stephens]

I only have one BSD box, and that is running PFSense, and fortunately (for me, 
anyway) I don't have to visit the OS.

I wouldn't have a clue with regards to BSD I am afraid.

So I downloaded the latest slackware and installed it.

I was up running straight away, no issues or bugs apparent.

Kernel source is installed with the distribution and I was able to tailor and 
recompile the kernel without any hassle whatsoever.

I tried, Scientific, Centos, Fedora and RHEL, they seem to have decided rolling 
your own kernel is a big fat no-no in all of these RH based dists. Fedora16 was 
an absolute shocker, just about everything was buggy or not working. 
Scientific, well is too much hassle to set up, RHEL is just plain annoying, 
Centos is about the best for me, but hey, I like to make my own kernel with 
only the bits I need and can't even do that on centos.

Slackware to the rescue :)


Many thanks,
Mark

Very easy... Add options PPS_SYNC to the file
/usr/src/sys/i386/conf/GENERIC.

Run

# cd /usr/src/sys/i386/conf
# config GENERIC
# cd ../.. (I believe but config tells you the correct path)
# make depend
# make
# make install

You know have a kernel with PPS support.

So I downloaded the latest slackware and installed it.

rolling out your on kernel is harder... as you say.

CentOS is also the best for me but only for standard servers.

My NTP servers are embedded machines that run FreeBSD (NanoBSD).

OK, here is a "clue".  BSD is enough like Slackware that you will do
just fine.When  Slackware came out (I remember when it was new and
came on a stack of floppy discs)  no one knew a lot about Linux and
BSD as the model.   My experience at that time was with SunOS (before
Solaris) and SunOS was basically BSD.  Slackware required almost zero
learning, just install and go and al my SunOS exprerience was usable

BTW I'm typing this on  a Fedora system at the office.  Not happy with
it any more.  I think I'm going back to BSD based Mac OS X.

BSD sounds too good to be true!

I'll try out BSD today if you try out the latest Slackware?

I remember downloading the 17x 1.44 floppies at 1200 baud.. 

There were no ISP's in Australia those days, we dialled straight into the 
internet backbone.

We had to install our own modem/server at Apana which is still going strong: 
<http://www.apana.org.au/>

Gosh, that was many moons ago..

[ntp:questions] New NTP server to add in the pool

[Elia S.]

Hello
I am the owner of an Italian small ISP, and I would like to donate a little

Thanks for helping to provide pool.ntp.org service -- we can always
use more pool servers to spread the load.

For future reference, adding a server to pool.ntp.org is a
self-service operation via http://www.pool.ntp.org/ (don't omit

operation.

You are confused between two different lists of NTP servers.

That is not true. The Pool has code to retrieve the PoolMembers from
