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

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 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

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

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

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

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.

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

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

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

Hello, I see manage of firewall in CentOS (called security), and seems difficult to manage, not enough powerful. I am searching a middle term between scripts of iptables to manage and Security manager of CentOS. I know FireStarter, another similar? -- Devel in Precio http://www.pas-world.com

Hi, I'll need to buy a new wireless card. I need a recommendation for PCMCIA wireless card that simply works with CentOS out of the box. By "works out of the box", I mean that it doesn't need ndis wrapper (or whatever it is called), kernel hacks, or whatever. Thanks

Hi Friends, I have an Excalibur 4GB USB Pen Drive Model Number EXC4. I think it is getting detected by the Centos but I am not sure about the mount point or the device point it is taking /dev/s??

I tracked down a createrepo rpm "for RHL 7.x, AS 2.1" etc (hosted by Dag), but it's uninstallable. Eventually I managed to create an rpm from the source (actually, that's fairly easy when onw knows to say "python2"), but python-urlgrabber has completely defeated me. According to Dag, the problem is that "upstream" doesn't see the need to support

hi gang! I'm interested in setting up incoming PPP on a system at work that has a fresh (not upgrade) Centos 4.4 on it. All the documentation I've found for that shows using mgetty to do it, and seems pretty straightforward. However, that machine doesn't have a binary named mgetty anywhere. It does have a mgetty-sendfax RPM installed, but it does not provide a binary named mgetty.

Hi, Does CentOS 5 / RH 5 ship with a similar windows active directory and able to support windows workstations? I've of heard OpenLDAP and FDS. Does windows support those? regards

Hi Guys, I'm creating an ldap server for my network. I'm quite confuse about /etc/ldap.conf and /etc/openldap/ldap.conf files. What are the difference of those two config files?

I just setup CENTOS 4.7 with latest patches on DELL server. I also configured NTP point to out time server. I found /var/log/messages file every 20 to 30 minutes will generate a error message : Mar 15 14:28:15 SER1 ntpd[25037]: sendto(172.29.21.16): Invalid argument Mar 15 14:45:22 SER1 ntpd[25037]: sendto(172.29.21.16): Invalid argument Mar 15 15:02:29 SER1 ntpd[25037]: sendto(172.29.21.16):

OK, So what you people say is : 1. Run "ntpdate" during startup only once 2. After that, keep time with ntpd Right ? Regards, spyros ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis
