General :: Synchronize The Time Of VM Server With Ntpd?
Mar 22, 2010
I am trying to synchronize the time of my VM server with ntpd. I have the following configuration. And in the /etc/ntp.conf, I have the following line:
restrict default ignore
restrict 127.0.0.1.
server time1.server
server time2.server
Whenever I have this line, the erver is not able to synchronize its time... So far as I understood, this line prevents other servers using this machine as a time server. And the second line says to allow localhost to use as time server. But why do I need to use its own time server when I have specified to use time1.server and time2.server ? ( firewall for tcp and udp ports 123 is open)
However, when I replace the first line of the configuration with the following line, it works. restrict default kod nomodify notrap noquery But with this, i am allowing other servers to use this server a ntp (which I wouldn't like to). Why this machine tries to use ntp server of its own (to snyc time) and why it is not working though i have the entry "restrict 127.0.0.1" ??

I have a set of machines on a disconnected network. Periodically, one of the machines connects to the internet and synchronizes its time with a time server that is not known until the connection is established. (The machine queries a central command server for the address of the time server it should synchronize to.)
I then use a custom tool to do some calculations to call adjtimex() and adjust the clock so that it runs fairly accurately.
I know ntpd is supposed to be able to handle disconnected networks but I thought you had to preconfigure the servers in the configuration file.
My intent is to run ntpd on this machine (without configured "server"s) so that it can serve time to the internal network. (Periodic synchronization using ntpdate from the internal machine to the bridge machine.)
The problem: ntpd wants to fuss with the values I set using adjtimex(). I want it to quit thinking it needs to adjust the clock and just serve time to the internal network. (Maybe I have a GPS time source hooked directly to the machine!)

I'd like to have a copy of a web site on my local drive. Then when I make changes to that copy, have those changes automatically updated on the site's server. Ideally I'd like to tell it to only do this for certain file types. Does anybody know of a way to do this with Linux?

I just installed antix. It asked for time zones and I set all of that up but it is 3hrs off. My computer clock is correct, why can't I just set up antix to recognize my computer clock? Or why doesn't it just use that as a default?

I have a server running VMWare Server on it with 4 virtual machines running. I am trying to use NTPD to keep the time correct on all of the virtual machines. On my physical server, I have installed ntpd and this is it's config file:
Quote:# ntpd.conf
tinker panic 0
restrict 127.0.0.1
restrict default kod nomodify notrap
server 0.vmware.pool.ntp.org
server 1.vmware.pool.ntp.org
server 2.vmware.pool.ntp.org

I'm having a problem with the time on one of my servers jumping forward into the future. We run serveral CentOS 5.4 servers running Xen, some up to date and some a little older. The one in question is running 2.6.18-164.el5xen, with xen-libs-3.0.3-94.el5_4.2 and xen-3.0.3-94.el5_4.2. On this server are several Xen virtual machines, also running CentOS 5.4 with kernel 2.6.18-164.el5xen. One in particular has problems with the clock keeping proper time.
We use NTP (ntpd) to sync time to a central server in the company. Our NTP set-up works fine, and we have problems on only a couple of servers out of many. The problem I see is that one one particular Xen virtual machine, the clock will suddenly jump forward into the future, usually by several minutes but once by more than an hour. This has obvious implications for software running on the machine. Software such as Oracle grid control agent will restart itself under the (incorrect) assumption that it has been hung for several minutes with no activity. Oracle database will cope gracefully, but applications that refer to the clock will be confused.
We detect these time jumps because we have Nagios checking the clock on each host against the centralised time server (Nagios's check_ntp plugin). Nagios will suddenly report a clock offset that is miles into the future. Following the time jump, ntpd on the host in question will re-sync the time. Ntpd keeps the time steady, ticking just a few milliseconds per second until real time catches up with the server. i.e. Nagios will report the time as being 10 minutes ahead, then a minute later the host will be 9 minutes ahead, and then a further minute later the host will be 8 minutes ahead of real time. The clock on the host stays running very slow until it eventually is correct.

I have an OpenSuSE 11.1 web server. For some reason the time will not stay with what I set it to.I go into Personal Settings and adjust the date/time and no matter what it keeps defaulting back to december of 2007.This is a virtual machine sitting on VMware ESXi 3.5. I noticed that the time in the BIOS was also off by the same date. I adjusted it there and still the time is incorrect within the OS.As soon as I boot into the OS, it displays december of 2007. I check the BIOS again and it reverts back.

I am having a situation with an NTPD server.
Code:
remote refid st t when poll reach delay offset jitter
plesk2.datacent .INIT. 16 u - 64 0 0.000 0.000 0.000
91.198.87.118.b .INIT. 16 u - 64 0 0.000 0.000 0.000
core.fr.zeroloo .INIT. 16 u - 64 0 0.000 0.000 0.000
178-26-105-100- .INIT. 16 u - 64 0 0.000 0.000 0.000
and it remains so no matter how long I wait...
Hoping to get better results with ntpdate, I stopped NTPS and tried :
Code:
# ntpdate ntp.skynet.be
29 Mar 09:12:26 ntpdate[4715]: no server suitable for synchronization found
# ntpdate -ud ntp.skynet.be
29 Mar 09:14:02 ntpdate[4814]: ntpdate 4.2.4p4@1.1520-o Sun Nov 22 16:14:35 UTC 2009 (1)
transmit(195.13.23.5)
receive(195.13.23.5) .....
I am running Debian Lenny 64b, and every packages are totally updated. I have 25 identical servers. And there is just one giving me this problem. From what I see, it is not a connection/FW issue since ntpdate get replies from the ntp server (ntp.skynet.be is my isp's stratum 2 ntp server).

What configuration options in /etc/ntp.conf do I have to set to allow other computers to receive time from a ntpd server? I've tried removing "nopeers" and "noquery" from the restrict lines, but I can't see anything on port 123.

I cant get ntpd to synchronize with the ntp servers. I have a CentOS 5.3 32 bit Virtual Machine. I'm in USA on Pacific Standard Time. Here's all configuration and other important information for troubleshooting. Is there anything wrong with my config? btw, I used wireshark to look at the UDP packets - I dont get any responses from any of the servers back. I only see requests going out from my server, but no response. Is this a firewall Issue? If it is, then do I need to just enable UDP port 123 on the firewall?

I have installed the synckolab add-on in thunderbird to synchronize with my citadel server. The calendar and tasks in te server are synchronized to my client, but not the other way round, i.e. the changes in thunderbird are not written to citadel. Contacts get synchronized ok, in both directions.
Setup is:
Has anybody on this list set up a working synchronization of calendar and task items with synckolab?

I have made a backup of my files on a remote server and I'd like to maintain that backup using rsync. The problem is that the timestamps don't match perfectly between the source and the backup.
What can I do? I'd rather not replace all the files in my backup because there is so much data it would take a very very long time.
Is there perhaps a way to compare checksums and then update the timestamps? Both are low power boxes with no GUI and only BusyBox CLI access.

I have two computers with Ubuntu 10.10 on them, a desktop and a laptop. I have two options for handling them:
Try and keep them the same
Accept that they have different 'personalities' and branch off their on way
However, I've chosen the first option because I like to keep my files and settings the same on both computers. I am in the process of extracting a tar archive I made of my entire desktop's hard drive (9.7GiB) onto my laptop, so after this is done they will be exactly the same. However, upon turning the laptop on with my freshly-copied system, things will become different. If I take the laptop to school, for example, and do stuff there, then come back home, and do stuff on my desktop, how can I sync these computers (both ways!) with the new changes at the end of the day/week/whatever?

Scenario: An IDE is set up on a Linux desktop box, editing PHP files locally. Every time I save a file, I want this change to appear on the linux server where Apache is running. The server has ssh (and samba and nfs for that matter).As a reference, when I edited files on Windows, I finally came over WinSCP as the exact tool I needed - WinSCP have just this feature present, with initial synch and then continuous update, using the filesystem watch service: "Keep Remote Directory up to Date".
On Linux, one could argue that sshfs could be employed to sidestep the need for synchronization entirely. On windows, a samba-share would do the same. However, I want the IDE to work with local files (on a SSD disk!), not having to go over the network to do PHP indexing and whatnots, which takes ages.But sshfs might be a part of the solution nevertheless - so that the continuous synchronization just needed to be done between two local directories.

I use Thunderbird in different computers so I configured it so that the datas are on an external drive. It works fine except that it seems that the contacts are still saved on the different computers and not on the external drive. It is strange since I have all datas for each profile on my external drive and all Mail and folders are there. I use different versions of Thunderbird (3.1 and under). how I could also have my contacts datas on my external drive?

I have several file servers in our offices and I am relatively new to Ubuntu / Linux. I get notices that there are updates for the server software from time to time. Is it typical to update everything when available or should I follow "If it ain't broke, don't fix it..." mentality?I would hate for everything to be working fine and then have an update throw me a curve.

I am hosting two Virtual Servers both running Centos 5.3 on a host machine also running the same OS. The VM software in use is Xen, as supplied with the OS.The host machine's time and date is fine, however both Virtual Servers are running ahead of real time consitantly.Running /etc/init.d/ntpd restart will resolve the issue however one of these is running MailScanner and when the time suddenly goes backwards, sometimes by as much as an hour, it stops working properly.
