CentOS 5 Server :: Sync Time With NTP But NOT The Date Possible?
Apr 11, 2011
I am trying to sync the time on my Centos 5 box, but I do not want to sync the date. All of our servers need to have the clocks synced, but one system needs to have the date set to the previous day.
My date and time is not syncing correctly. I have 2 opensuse 11.1 servers and on both when you adjust the time in yast, I go back into yast and the setting for the NTP server is not set and "manual" is checked. I tried many times and the setting keeps reverting back. I always click on Save NTP configuration.
I have a CentOS 5.3 server. All of the other computers I have are Windows or Ubuntu. The Ubuntu machines sync to the time on the CentOS machine correctly. The problem is, some of the windows 2000 Pro and Windows XP Pro machines are an hour off when they sync. The CentOS machine is set to New York time.
When I run: (Assume the time is currently 10:06 AM on the server) net time \xxx.xxx.xxx.xxx /set /yes
On the correct machines I get the message:
Current time at \xxx.xxx.xxx.xxx is 11/1/2010 10:06 AM
The command completed successfully.
But on the other machines I get:
Current time at \xxx.xxx.xxx.xxx is 11/1/2010 9:06 AM
Local time (GTM-04:00) at \xxx.xxx.xxx.xxx is 11/1/2010 10:06 AM
The command completed successfully.
Then the time on the windows computer is 9:06 instead of 10:06.
Is there something that needs changed on the CentOS Machine for the times to be correct?
I have one server running a daily cron to sync its time using ntpd:e.g.ntpd -qgI would like to sync my second server's system time to my first server. How can I do this?
I am currently using curlftps to mount a directory on a ftp server locally as /backup , I then use rsync to do an incremental backup to this directory every night and a full backup at the weekend.A requirement has arose for a similar set up but one that syncs in real time, so if a user puts a file in a directory it immediately copies that file to my ftp server, in this case it immediately copies it to /backup
I live in Egypt and we used to have Daylight Saving Time in this time of the year. But due to some political conditions, this decision was revoked and we are not using DST this year. The problem is that my Redhat 5.6 machines, configured to the timezone Africa/Cairo has already set the DST (UTC+3). The current time in Egypt is UTC+2. Of course I can manually set the time but the servers are set to sync automatically with an NTP time server so that time gets synced automatically whenever I try to change it. I want a way or another to disable DST switching.
I want to make one Fedora 14 as server that have Date and Time as normal. Is there any to make other fedora 14 get Date and time from that Fedora 14 server
we have a minor issue with time synchronization in proprietary equipment.the client needs to synchronize time with server, but not using NTP.it is not very important so doesn't need to be done often.the problem is that it won't synchronize. I can see the server is sending tcp packet with date&time, but the client ignores it.I suspect the problem is in format (manual specifies there are two possible options like MM: DD: YYYY and so on, but server seems to use some other)Is there an easy way to run some program in Linux Debian, to send that simple packet with correct date?
I've got fedora 11 set up to use network time protocol to sync my laptop's date & time when I'm on-line. The question is simple really, I've added a local universality's time server (what is public) and it's live. but it's added to the end of the default time servers what come with fedora. How do I get fedora to just use the local time server, is it a case of removing the default time servers for fedora, but there is a box what says advanced options which are. sync system clock before starting service ???? & use Local time source (( is that the same as the local ntp server that I've got set up ))Hope some body can help me with the network time protocol part of Date/Time settings.
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.
I installed my linux os in vmware.I need to set time of virtual machine to later time( 2005 ).I have an application whose license expires at 2006 so I have to do this in order for it to work .but when I change it it comes back to the current time ,so what is the solution for this .
If one right-clicks on the date and time tab in Ubuntu 10.10 desktop, then there is no obvious way to change the time. If one right-clicks and goes to help, then the explanation for changing time is as follows under the category 'usage':
2.3. To Adjust the System Date or Time.
To adjust the system date or time that the Clock applet displays, perform the following steps:
1. Right-click on the applet, then choose Adjust Date & Time.
2. Type the root password, then click OK.
3. The Clock applet starts the system tool that sets the system date and time. Use the tool to adjust the date and time.
The actual way to do this is as follows:
Right-click on the date and time applet. select preferences, and down at the bottom of the window that opens push the 'time settings' button.
Then you will be able to adjust that date and time.
rpm -qa --last lists all rpm with date and time. But I want to sort the list by date, with earlier rpm displayed first. So it needs pipe, rpm -qa --last |
I was wondering if anyone has discovered a way of either using cron or by custom scripting, to run a script at a certain date and time only once. The purpose would be to make one-off changes to dns zone files, or to virtual host configs on an apache server, or changing any type of text file at say 12:01am rather than waking up at 12:01am (when our maintenance windows start) to make changes to production servers.
I set my location, but Debian displays DATE in some messed format. I would expect such neat OS to recognize all those local settings based on my location, but that's not the case. It seems that Debian follows locale settings by set language (which is en_us in my case, as I guess in majority uses) or this format is default in any case
I would like to set date/time to DD.MM.YY. hh:mm:ss, and programs that display date data to follow this setting. Simply put, in Windows there is Control Panel and you set location, then OS uses some regional settings, like currency, separators, date/time format.
How do I know the time and date of a file downloaded from the net. Is it possible at all? If I want to know when the downloaded file such as a text file was created ie written by the author if not mentioed at all in the entire document. The command I use locally to know file creation time is given below.
Code: ls -l filename.txt -rw-r--r-- 1 root root 691 Dec 3 11:12 filename.txt
In the past, I just edited the /usr/share/gnome-shell/js/ui/dateMenu.js file to alter the date and time format. Today when I tried that, it crashed GNOME Shell and wouldn't let it start..
For some reason, thunderbird uses some random order for the date elements, e.g. MM/DD/YY. I need to change it to YYYY/MM/DD but haven't found where! There is no option in TB to configure this so I guess it just picks some default from regional settings? Where do I need to go to set the date format to its logical form?
I've noticed that every time this desktop is turned on the date & time are as they were the last time I used it, and then have to put in the correct date & time again (this is why I chose the word 'persistent' within the tittle). When I try to change those have to write in the password for the date as well as for the time as if 'login-in' once were not enough! What I want to know is how to put in the date & time and receive the correct amounts the next time I turn the unit on again, as it should be? Do I've to open a terminal & do it with administrator's authority/credentials?
ubuntu 10.10 64bit my system clock keeps running late, and for some reason, I can't use NTP to synchronize it.If I try to use System -> Preferences -> Administration -> Time and date I can't unlock the popup (see attached screenshot) - I can click on the little yellow lock icon but when I do so, nothing happens.I tried "sudo ntpdate..." but i get the "the NTP socket is in use, exiting" error.
