similar to: ntpd heavy CPU consumption

I could use some input to point out the error in my configuration, which eludes me. Previously I operated a 225-node cluster with samba 4.3 and sssd on the Linux boxes. Everything worked OK. Now I am using samba 4.11.6 on CentOS 7.7, patched up to date. The DC, on a KVM VM, is the only node configured so far. I am using winbind in place of sssd (my first experience with winbind).

This idea is intruiging... Suppose one has a set of file servers called A, B, C, D, and so forth, all running CentOS 6.5 64-bit, all being interconnected with 10GbE. These file servers can be divided into identical pairs, so A is the same configuration (diks, processors, etc) as B, C the same as D, and so forth (because this is what I have; there are ten servers in all). Each file server has

Hi, I have got problems with the ntp daemon. It is enabled in systemd but is not started on boot. # systemctl status ntpd ? ntpd.service - Network Time Service Loaded: loaded (/usr/lib/systemd/system/ntpd.service; enabled; vendor preset: disabled) Active: inactive (dead) Starting manually works # systemctl start ntpd # systemctl status ntpd ? ntpd.service - Network Time Service

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

Hello, all. I would like to use ntpd for time sync not rdate or ntpdate. but after installation the ntpd, I found that listened at all interfaces like below. udp 0 0 192.168.111.2:123 0.0.0.0:* 11528/ntpd udp 0 0 xxx.xxx.62.20:123 0.0.0.0:* 11528/ntpd udp 0 0

Hi, I'm in the middle of migrating our oracle servers to RHEL and C6; while testing ntpd I'm seeing time resets. I see in sysconfig/ntpd the option g is set which means huge offset is one time ignored. But my understanding of ntpd is, it slows or accelerated kernel clock but does not make huge jumps... Is this really expected behaviour? The file step-tickers is empty, ntp.conf is

I am running a server inside of VMWare, and the clock gains ~30 seconds every 1000 seconds or 1.03X. I need to keep the drift under the magic 1000 limit that ntpd kills its self, but despite setting maxpoll really low I get: Dec 11 23:58:14 host ntpd[4909]: kernel time discipline status change 41 Dec 11 23:59:17 host ntpd[4909]: kernel time discipline status change 1 Dec 11 23:59:17 host

This is really stupid question. But referring to: http://lists.centos.org/pipermail/centos/2009-October/083791.html I don't see any line related to ntpd in my /var/log/messages . Do I need to turn-on ntpd for timekeeping on VMs? Some people say not to use ntpd on VMs for timekeeping or is it ntpdate cron job? Can someone please elaborate on this? Thanks, Jonathan. -------------- next part

Hello *, strange happening yesterday. See this logfile lines: Sep 10 20:45:52 seymour ntpd[9104]: synchronized to 192.53.103.108, stratum 1 Sep 10 20:58:07 seymour ntpd[9104]: synchronized to 134.34.3.18, stratum 1 Sep 10 21:21:02 seymour dovecot: dovecot: Fatal: Time just moved backwards by 434 seconds.

Scenario: server PC abruptly switched off due to power cable problems (an UPS cannot solve this issue), so during shutdown Linux was not able to resinchronize the system clock. After a few hours the server come back on, Linux booted and the services (ntpd, dovecot and many others) started But the system clock was 45 minutes ahead, so: Jan 19 11:13:39 gw ntpd[2112]: synchronized to LOCAL(0),

Hi guys, Thanks for your reply. I originally used the following command to synchronize time: ntpdate 192.168.0.191 but got the error: ntpdate[16715]: the NTP socket is in use, exiting So i used the way of stopping ntpd service. Now I have known that using command "ntpdate -u 192.168.0.191" can solve the above error, and also know using ntpdate command is an improper way, i.e. should use

Hi, As Centos 7 and Fedora defaults to chronyd [2] , should I use ntpd for some reason [3] ? I based my configurations on [1] which use ntpd ... but I thinking change for chronyd , change ntp deamons could outage the samba service and client computers ?

Hi All, Currently CentOS site contains the below version of ntpd. ntp-4.2.6p5-3.el6.centos.x86_64.rpm<http://mirror.centos.org/centos/6.6/updates/x86_64/Packages/ntp-4.2.6p5-3.el6.centos.x86_64.rpm> :- 16 mar 2015. Does anybody have any information about when the new version of ntpd is expected to release containing new vulnerabilities fixes? Thanks Vijendra.

Hi there, I've been a happy djbdns+tinydns user for many, many years. I want to keep using it, so answers of the form "bletch! Use ISC BIND the way BSD intended" will be ignored :-) Having said that, one annoying consequence of my transition some time ago to using ntpd, rather than just setting the clock once-off with ntpdate as I used to, is that the /etc/rc.d mechanism starts

I'm running latest CentOS 4.3 (2.6.9-34.0.2.ELsmp) and found that the included 'ntpd' 4.2.0a at 1.1190-r will not accept NTP broadcast packets. There is a documented bug in ntpd 4.2.0 to this effect, resolved way back in 2004: https://ntp.isc.org/bugs/show_bug.cgi?id=267 Any chance someone can include a more recent version of 'ntpd' in the next CentOS RPM update

A CentOS 6.3 box ("host") runs several KVM virtual machines, each of which has two interfaces attached to the two bridges br1 and br2 (and each thus has two IP's; one on 192.168.0.0/22 and one on 192.168.4.0/22); net.ipv4.ip_forward on the host is 1. Simplified diagram: host +---------------+ |

CentOS 5.7 x86_64. Lots of hosts NFS mounting a file system. All are configured identically (same LDAP servers, same DNS, same autofs config, same patches, etc). On some of them I see an NFS mount displaying a host name: % df -P | grep smt <hostname>:/mnt/foo 1651345888 264620688 1386725200 17% /fs/home/smt and on some just the IP address: % df -P | grep smt aa.bb.cc.dd:/mnt/foo
