similar to: NTP traffic blocked

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

Hello All, My name is Gaurav, and I am tasked with configuring a linux box with NTP. I am having a problem that I hope you can help me with. We have installed CentOS V5 on 1 processor down in the lab. The rest of the processors on the network are AIX boxes versions 3.2.5 and 5.2. I worked through the entire initial NTP configuration; setup the /etc/ntp.conf file to point to the server, etc.

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

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 thought I'd play with making my system an ntp server. I did the "service ntpd start" it started OK. on my laptop I did "ntpdate IP" and it says no server for sync found. My firewall has open ntp:udp What did I miss? Thanks, Jerry

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

I have a Centos 5 64-bit server that has ntp service enabled. Windows XP with SP2 cannot properly sync to it for time, but can communicate with it via samba, ssh, and anything else. I also disabled the Windows Firewall. The C5 system does not have any firewall enabled. Other C5 workstations can successfully sync to it via ntpdate. What else could cause the XP machine to not be able to

In our network we found some client with clock differences. Some machine have effectively some troubles, eg have NO 'Windows Time' service defined, probably some glitches happened when moving from our old NT-like domain. Anyway, catching for that, we have found some other strangeness. Windows time service run: C:\Users\gaio>sc query w32time NOME_SERVIZIO: w32time TIPO

Hello I am trying to sync via NTP locally (since I have no Internet access). None of the NTP stuff I read on the net seems to work right. I mean it works fine setting up a client going to something like 0.pool.ntp.org but when I want to make my LInux box a server, and I do an ntpdate to it from another machine, it says no suitable server found. I have tried every possible combination of

I noticed this morning that my ntp time was not correct on machines. So I manually ran "ntpdate time.apple.com" on my clients, I got 7 May 08:46:43 ntpdate[10550]: no server suitable for synchronization found then I ran "ntpdate -d time.apple.com" and it worked . filter offset: -163.446 -163.446 -163.446 -163.447 0.000000 0.000000 0.000000 0.000000 delay 0.20570,

I'm building a new Ubuntu 16.04 machine, including Dovecot. When I select the dovecot-core package in Synaptic, it also wants to install ntpdate. Problem: ntpdate has been replaced in Ubuntu with timedatectl. In fact, if ntpdate exists on the machine, ntpd will not work properly. See: https://help.ubuntu.com/lts/serverguide/NTP.html See:

Hello everybody, I just tried to run 'yum update' and got this error: Error: Package: ntp-4.2.6p5-19.el7.centos.x86_64 (@updates) Requires: ntpdate = 4.2.6p5-19.el7.centos Removing: ntpdate-4.2.6p5-19.el7.centos.x86_64 (@updates) ntpdate = 4.2.6p5-19.el7.centos Updated By: ntpdate-4.2.6p5-19.el7.centos.1.x86_64 (updates) ntpdate =

I've curious about where and how Centos 7 gets its ntp configuration from. When I installed the operating system, I went through this page and told it to use "network time", as shown: http://media.if-not-true-then-false.com/2014/07/06-centos-7-date-and-time-748x560.png I just discovered that i don't actually have ntp installed on this computer, though the rpm does exist when I

I think it''s perfect the way it is. Run NTP in dom0, all the domU''s then have synchronized time. I can still set timezones on all of these boxes independantly. Timezone has nothing to do with NTP synchronization. Tim:> > yeah, i''m already doing that, I was just saying, it *seemed* > like they were getting their time from domain0, and weren''t >

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, I''m trying to run ntpdate from domain zero and getting weird results. This used to work (prior to using xen). Is this related to xen at all or an entirely unrelated issue? Queries seem to work: # ntpdate -q time-b.nist.gov Looking for host time-b.nist.gov and service ntp host found : time-b.nist.gov server 129.6.15.29, stratum 1, offset 41.820087, delay 0.17027 17

I have read: http://thegeekdiary.com/centos-rhel-7-chrony-vs-ntp-differences-between-ntpd-and-chronyd/ My server is up all the time and will serve time to internal systems (via DHCP options). Caveat is that my server is an armv7 (Cubieboard2) which does not have an RTC (no battery). So whenever the system boots, the time is ZERO (Dec 31, 1969 or some such). Chrony fixes this really fast;

Hi all, my first post. After years with an old server, a couple of months ago I've installed a new one. We use IMAP. After research, I chosed dovecot. It has been running for several weeks but from one week ago or so, it suddently dies about once per day. The only change done in the server one week ago has been to install ntpdate, running once per day in cron-daily. In the cron
