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

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

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, I'm currently sinking my teeth into NTP, to build a local time server. So far, configuring a local NTP server and getting the clients to connect to it works well. Now, I'm thinking about securing the whole thing. BTW, I made a copy of the original ntp.conf file and started my own from scratch. Right now, I have five printed books opened on the corresponding chapters (Carla

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

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

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 am running ntpd on the same machine as asterisk in order for the grandstream phones to display the time. After a while the time display fails until the phone is re-booted. Has anyone run into this problem before? Is it simply a bug in the GS firmware? Sean

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: restrict 192.168.128.0 mask 255.255.255.0 nomodify notrap But in looking for documentation on chronyd I did not find anything on this at: https://chrony.tuxfamily.org/doc/2.1/manual.html In the actual /etc/chronyd.conf

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

AFAIK the only thing needed to make your host an NTP server using chrony is to set the allow line to the network address in CIDR format of the network you want to be served, and uncomment it. The restart chronyd. You also need to ensure that port 123 (NTP) is open to your internal network on your filrewall. I have a CentOS 6 box that is an NTP server for my network. CentOS 7 works the same

It appears that none of our windows clients are syncing their time with the samba DC.??? From what I can tell they are not able to get a response from the DC.? For example, where the DC is named athena: >w32tm /monitor /computers:athena athena[10.10.1.10:123] ? ICMP: 0ms delay ? NTP: error ERROR_TIMEOUT - no response from server in 1000ms From a Linux machine there is

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.

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

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
