I'm running 9.2-RC4 on a handful of desktop and server machines (both i386 and amd64). I have seen three panics (all vm_page_unwire) on one of those systems only (amd64 server) during the past week. The first two panics were triggered when shutting down the ntpd daemon (a recent development snapshot version of ntpd: 4.2.7p387). Exiting a later release (p388) has not triggered the panic.

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: [admin at lol ~]# date Wed Jan 27 10:54:21

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

Hello everyone, I was trying to configure NTP server in my samba4 server but it's not working. I am using CentOS 6.3 (32 bit) for my samba4 server. I installed ntp using yum and the ntp version is 4.2.4 added this line in /etc/ntp.conf restrict mynet mssntp signdsocketdir /data/samba/samba4/prefix/var/run/ntp_signd/ and restarted the ntpd server but my clients are not syncing with the

I have installed samba AD in centos 7, but I have an inconvenience to synchronize my clients with the NTP service, the status is in failed, it has to do with the socket. What permissions should be assigned? [root @ adsserver ~] # systemctl status ntpd ● ntpd.service - Servicio de hora de red Cargado: cargado (/usr/lib/systemd/system/ntpd.service; habilitado; proveedor preestablecido:

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

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 out

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):

Robert, If your NTP server will be on 7/24, I would uninstall chrony and install ntpd which is still included in CentOS 7. Configure as usual. For the differences between chrony and ntpd reference: http://thegeekdiary.com/centos-rhel-7-chrony-vs-ntp-differences-between-ntpd-and-chronyd/ Essentially, chrony is more for laptops with intermittant network connections, and ntpd is better suited to

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

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

A shell script is deployed to synchronize time, the script is invoked hourly by crontab, and its content is as follows: #!/bin/bash service ntpd stop ntpdate 192.168.0.191 #it's a valid ntpd server in LAN service ntpd start chkconfig ntpd on Inspected the Linux log(Centos6.4 /var/log/messages), found the following fragment: Jan 7 14:00:01 host1 ntpd[32101]: ntpd exiting on signal 15 Jan 7

Hallo, I am running dovecot on a PC (a workstation) to have a mail client independent storage for my mails. Now I would like to have the system clock set correctly by using ntpd or ntpdate (using debian/sid). The problem is, that the PC is not online at boot time, but is set online on demand manually using "pon" to start the pppd later. So ntpd cannot sync the time on boot time

Hello Dear Friends, it is CentOS Release 6.2, ntpd is running but do not see bounded to the port udp:123 any guidelines would be very much appreciable. [root at jet mavi]# netstat -ntlp | grep ntpd <nothing in output> [root at jet mavi]# netstat -ntl | grep 123 <nothing in output> But the service is running - [root at jet mavi]# /etc/init.d/ntpd status ntpd (pid 15876) is

Hi all, I have a problem with ntpd daemon in my CentOS7 vm. When I try to list peers, command fails: [root at c7tst ntpstats]# ntpq ntpq> pe ntpq: read: Connection refused ntpq> My actual ntp.conf: # For more information about this file, see the man pages # ntp.conf(5), ntp_acc(5), ntp_auth(5), ntp_clock(5), ntp_misc(5), ntp_mon(5). driftfile /var/lib/ntp/drift # Permit time

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

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

What Marco and Robert already did say.   This is what i mean ( and Robert ). Marco's option to disable though kernel is also an option.   Maybe a bit cryptic but like this.   HOST              - CONTAINER - SambaDC- samba-AD distibuting time to PC's. ||                         ||| HOST_its_NTP_Service  => get Internet time  |||| OTHERHOSTS NTP Client - COINTAINER - SambaMember  -

FreeBSD-12.1p7 Samab-4.10.15 running in FreeBSD Jail I just wish to ensure that my conclusion respecting Samba, FreeBSD Jails, and NTP is correct. 1. Unless configured otherwise Windows domain clients will query and obtain their time from the samba_server DC. 2. Samba_server obtains its time from the OS, in this case a FreeBSD Jail. 3. FreeBSD Jails get their time from their host. 4. If

Default install with local_unbound and ntpd can't be functional with incorrect date/time in BIOS: Unbound requred correct time for DNSSEC check and refuseing queries ("Jul 1 20:17:29 yellowrat unbound: [3444:0] info: failed to prime trust anchor -- DNSKEY rrset is not secure .
