similar to: ntp server

I’m currently trying to install a new (primary) AD DC in a Linux container. It seems to me that being in a container, the DC is easier to maintain and backup than on bare metal, and I prefer a container over a VM for performance reasons. If the container setup will prove to be too much of hassle, I’ll switch to a VM, though. The first issue I’m facing is time synchronization. An container cannot

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

Hi Louis, In general, this sounds like the solution I was looking for. But I’m still a bit unclear about the practical implementation. So, the DC can be setup without ntpd as it will work based on the system clock which, in turn, is actually being updated by the container host using NTP. Which means we’ve got the DC itself covered. But if ntpd is not installed, then how can the DC serve 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 restrict default

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

Hi, I configured my NTP server in samba 4 according to the article " https://wiki.samba.org/index.php/Time_Synchronisation" however I verified that the NTP server does not respond to requests from Windows NTPv3 clients, it only responds to NTPv4. Following my ntp.conf: # /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help driftfile /var/lib/ntp/ntp.drift # Enable this if

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

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

I'm running a Samba AD DC v4.9.9 with Windows 10 clients connected to it and just noticed that the clients are not synchronizing time with the server. I'm not sure why not. My setup is a bit special in that the DC is running inside a (privileged) linux container. For that reason, it's not possible or necessary for the container to correct the system clock, this is done on the

Made the suggested adjustments (4 locations in the member server ntp.conf file) and restarted ntp. Still (member server) timing out. Not sure what you mean about removing "server 0.debian.pool.ntp.org iburst" lines. Those on the DC's. Aren't they necessary? Running 'ntpq -p' on DC's results in correct response. --- ------------------------- Bob Wooden of

Thank you, Rowland. Copied your simpler ntp.conf file into my member server. Made the appropriate changes. Restarted all the ntp service on all machines (just in case.) Ran 'ntpq -p' (on member server) and got the correct answer. Proper connection to DC's. --- ------------------------- Bob Wooden of Donelson Trophy 615.885.2846 (main) www.donelsontrophy.com [1] "Everyone

I guess your DC take the time from an external ntps server. But I want to serve time from the same DC, so this is my ntp config: #nano /etc/ntp.conf server 127.127.1.0 fudge 127.127.1.0 stratum 12 ntpsigndsocket /var/lib/samba/ntp_signd/restrict default mssntp ___________________________________________ Felipe_ González_Santiago KNOW THAT EVERYTHING WILL HAPPEN AT JUST THE RIGHT TIME,

We have a local time server and all of our machines are pointed at it for the time. How can the clock drift by a day and a half?

I have two DC's running Version 4.1.16-SerNet-Debian-9.wheezy and a member server running Version 4.1.11-Debian. When I 'ntpq -p' from the member server I get: localhost: timed out, nothing received ***Request timed out Member server ntp.conf file: cat /etc/ntp.conf # Local clock (this is not the localhost address!) server 127.127.1.0 fudge 127.127.1.0 stratum 10 # The source,

On my member server, running 'ntpq -p' yields: ntpq -p localhost: timed out, nothing received ***Request timed out The ntp.conf file is trying to use the DC's hostnames addresses: user at DC01:~# cat /etc/ntp.conf # /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help driftfile /var/lib/ntp/ntp.drift # Enable this if you want statistics to be logged. #statsdir

Copied Roweland's DC ntp.conf file into my two DC's. Restarted (all) ntp. Member still timing out! (I am starting to think that there is 'something' about the sernet packages that "they" do differently.) Rowland, Could I ask you to copy the ntp.conf from your client (appears to be your laptop) so I could review it's contents? --- ------------------------- Bob
