Correct NTP Settings for Samba 4.0.6?
Hello,
I recently compiled Samba 4.0.6 (as an AD DC) and am running it on Ubuntu 12.04.
I followed the instructions on the Samba wiki (https://wiki.samba.org/index.php/Configure_NTP)
for how to configure ntp, however the domain clients are rejecting the DCs as
being acceptable time sources. Below is my ntp.conf:
server 127.127.1.0
fudge 127.127.1.0 stratum 10
server 0.pool.ntp.org iburst

Samba4, NTP, and Ubuntu 12.04
Hello,
I have a question regarding signed NTP support for Samba4 on Ubuntu 12.04. I have followed most of the steps outlined here:
https://wiki.samba.org/index.php/Configure_NTP
These steps I did differently are:
* I did not install from source because the latest Ubuntu package for ntp available on Ubuntu 12.04 includes ntp-signd support already
* I did not install Samba4 to /usr/local/samba, so

ntp and samba43 on FreeBSD-103.
Recently we have been having a lot of trouble with time
synchronisation between our samba DC and the domain clients. We are
not sure what started this issue since the Samba domain went live on
October 11, 2016 and the issues only began to surface this past
January but at some point the time on the clients and the DC diverged
enough that we began to get strange network errors. Once we figured

HOWTO Stratum 1 NTP server under CentOS 7
Hello everyone,
If anyone is interested, I have created a HOWTO
on running a Motorola GPS receiver connected to
a CentOS 7 box via serial port (com1),
with 1PPS over DCD.
The trick here is that CentOS 7 uses systemd
and setup was a bit different. Anyway,
everything works.
The result is a highly accurate NTP server, Stratum 1.
Here is the documentation.

ntp revisited (so what to do ?)
OK,
So what you people say is :
1. Run "ntpdate" during startup only once
2. After that, keep time with ntpd
Right ?

NTP
Greets!
Ok. I'm looking at a client that needs to keep their server time close
as reasonably possible (within a minute) of the actual time of day.
I've installed the RPM for NTP and I'm looking for tips on what the
simplest setup should be, ie:
What server(s) should I be using for sync?
Should I just run it from a cron every 20 minutes or so?
thx.

NTP on CentOS 3.4
Running CentOS 3.4, I enabled the ntpd service and noticed that it
opens up a hole in the firewall for ntp from 127.127.1.0. I look in
the ntpd initscript and see that it's reading in servers from
/etc/ntp/step-tickers. However, that file is empty...
/etc/ntp/ntpservers contains clock.redhat.com and clock2.redhat.com,
but ntpservers isn't used *anywhere*.
This looks like a bug, but

HOWTO Stratum 1 NTP server under CentOS 7
Alexander,
First off, CentOS7 came with cronyd. Which was very annoying
because when I tried to remove it, it had 2 prereqs:
anaconda
initial-setup
Now, I don't know why the setup program kept these
2 around. I think CentOS7 needs a bit growing up.
Anyway, I disabled chrony:
systemctl disable time-sync
systemctl stop time-sync
Then I installed ntp. However, when I started it
it seems that

ntp server
I have a need to run a centos server CUT-off from any connected network.
So the NTP server that is running on this very small network cannot
connect to
any other site to do what NTP does.
however, I have devices on this small network that I wish to use the
centos server
as the time source and run ntpd.
However - it seems like ntpd server does not like to run this way.
There is a LONG delay

NTP and virtual guests
We encountered a problem with respect to KVM virtual host restore and
NTP. Specifically, our VM test host was shutdown by an extended power
outage and when power returned all of the restored guests were
immediately shutdown by ntp because the time differential between the
restored systems and that of the ntpd sync servers exceeded the panic
threshold.
This is not an acceptable situation so in the

Strange NTP problem
I have 30 identical Lenovo desktop systems running CentOS 5.1. On
one of those systems the clock is running slow (5+ minutes from
yesterday to this morning and another minute since this morning)
despite the fact that NTP is running on all of them and they all have
the exact same /etc/ntp.conf file (I compared the MD5 sums of that
file on all the systems). Here is the output of

NTP and hardware clock
Hi,
I had the following problem today. Because of a misconfigured
network switch one system suddenly didn't have any network.
After a reboot (with the network still unavailable) NTPD refused to start.
Most likely because the initial ntpdate failed to work. I find this
troubling, because when the network was restored, NTPD could have resumed
working (like I'd expect from a true

NTP Service Running on Local Host does not Sync System Time
Hi List
I have ntp running as a service on a PC, with the expectation that it
would keep time in synch to my ntp server.
However, while I can manually update the time using "ntpdate -u ...",
I find that if I manually force the wrong time, the ntpd service does
not automatically re-synch the system time with the ntp server:
- Current time:

chronyd configuration as a local ntp server
This is for centos 7 that has chronyd 2.1.1
I am looking into how to use chronyd as my local ntp server.
On my old servers with ntpd I had local access control lines like:

But in looking for documentation on chronyd I did not find anything on

ntp will not drift to correct time
Hi
On 5.3 i have a situation where some boxes have been 3 or 4 seconds out
and restarting ntpd has fixed the issue.
What i dont understand is why the clocks did not drift to the correct
time when the config seems correct in that restarting ntp did correct
the time.
Is there something 'special' i need to do in order for the drift to work?
$ cat /etc/ntp.conf
