Chrony vd NTP
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;

dovecot and ntp: Fatal: Time just moved backwards
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

NTP Service Running on Local Host does not Sync System Time
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:

DC Time Problems
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

NTP traffic blocked
I have multiple VM's on the same KVM host. One of the VM's is running NTP.
All VM's can reach eachother, no firewall in between. But the problem is,
the VM's cannot communicate over port 123/udp to the NTP VM.
Network: 172.24.100.0/22
KVM: 172.24.101.50
VM ntp: 172.24.102.10
VM foo: 172.24.102.20

time synchronization problem (using NTP)
Hi,
using SLES10 I''m unable to synchronize the time of DomU with that of Dom0. There
is a persistent offset of about 3 seconds!

Dovecot dies, maybe ntpdate related. I'm new to dovecot
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.

ntp queries not being answered
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.

ntp server
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

date differs permanent some 3450 sec.
Hi,
the date jumps within 30 seconds to a wrong value. ntp service is
stopped at the beginning.
Whereas hwclock seems more precise.

NTP strangeness...
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:

Fwd: ntp help
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
