Fedora :: NTP Time Keeps Drifting Into The Future?
Jan 25, 2011
I have a F14 laptop being used as a music server. For some reason the clock time runs fast and slowly drifts forward about 5 minutes/day.
ntpd is running. The ntpd.conf is pretty much F14 out of the box and the same as my other F14 instances that do not exhibit this problem. If I restart ntpd, it syncs up the time, but then the time slips until the ntpd seems to give up.
Initially ntpd reports it is synched,but then over time it reports being unsynchronized.
Shortly after restart:
Code:
ntpdc> sysinfo
system peer: w1-wdc.ipv4.got-root.me.uk
system peer mode: client
leap indicator: 11
stratum: 4
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'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 am a long supporter of Ubuntu and faithfully been updating every release from 8.04 till 10.10 ...I use an old Laptop with 512 MB RAM.I was not able to run the default Unity and I was dropped to GNOME .. This is the first time I am seeing a difference in Ubuntu trying to cater only to the more modern computers,.. Is the original spec of 384 MB RAM in previous versions no longer hold good?
I have an NVIDIA Card but I guess that is not enough..Any idea what is the problem in my config:Dell Inspiron Centrino Proc (1.4Ghz) , 512 MB DDR 1 , Nvidia.
the time on system clock given with 'date' command keeps moving forward about 1 minute for every hour of realtime. The box is up all the time so this is not an issue with motherboard battery. An equivalent box with the same hardwre/OS and applications doesn't have the same level of drift. I'm not sure what else this could be.Both boxes are Centos 5.2 64-bit.
When booting Fedora 11, my system hangs for a very long time on starting udev. Sometimes I get an I/O error. However, my hardware is fine. I do eventually get in to the system.
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.
Anybody worried about KDE future. KDE use the Qt toolkit and Nokia the owner of Qt is going all Windows on there phones. Does anybody know what may happen. Just wondering.
After the Nokia-Microsoft deal, the future of Qt doesn't look very bright. Many developers think that Nokia has no interest in Qt for the desktop. [URL] And since KDE is based on Qt, and KDE is the (sort of) default desktop environment for Slackware.
I have a few questions related to the 'Save Session for Future Login' option you can check (and is checked by default) when you go to shutdown/restart/etc.
1) What exactly does checking this option and shutdown/restarting do?
2) Is there any way to have it unchecked by default?
3) Is there any way to completely remove the option?
I am considering buying a netbook and installing the netbook remix from a bootable USB. During the installation, does the installer give me the option to create a dual boot scenario and keep the windows 7 as a partition? If it does not, what is the best way to clone the windows 7 install and can I put it on a usb to boot and install from in the future?
I have a concern regarding my clock in fedora 12. It always changes time even when I do not change it.
In fedora 10, I to go to CLI > time config > uncheck UTC, But now, it doesn't seem to work. Code: [jun@localhost ~]$ time config Command not found. real0m2.875s code...
I am looking to do just as the title says. If I no longer want to keep ubuntu say a year from now. Will i be able to uninstall or possibly delete the partion with ubuntu on it without wiping out windows? I ask because I am not sure of how much space I would like to partition, this way I could always come back delete it and then reinstall it to the size I wish
I downloaded a file enclosed in 58 rar parts and extracted them. I was looking for a way which would enable autodelete of all rar-archives after the extraction so I don't have to clean the mess up later. I hear there is some option in command line arguments but that doesn't work with split archives. Is there a way in GUI? Some option maybe, which I could check to make all the future extractions in par with autodelete feature?
I'd like to find out if it's possible to download and store (not install) official Ubuntu installation files, and then choose to install them whenever. I don't always have internet available and having to be connected every time I want to install a program really sucks. What happens if I had to format or something and I just wanna install all my programs again but no internet connection? Is there also away I can back up my Ubuntu and when I restore, I get all my downloaded and installed programs back, without having to re-install?
I'm going round everyone I know installing Ubuntu on their computers whether they like it or not, and I must say so far they all like it except. I have to spend 5 hours downloading and installing all the software they need to make their system run 'as good as windows'.
I really need a whole bunch of popular programmes to put on a disk and install as I go. I know Ubuntu saves the downloads in a repository on the hard drive, but looking at it I am sometimes at a loss as to which folders contain which downloads, then there is the problem of multiple folders for one programme etc.or point me in the direction of a zipped up file with all the programmes a normal user might need.
i am currently running 9.10 and was thinking of upgrading to 10.10. i was going to initally install 10.10 but i saw that it ran fluendo. does that mean the ubuntu restricted extras aren't in the future versions? i was also wondering if i would have to reinstall all my old programs.
I just switched to a faster isp with monthly usage limits. When I install a program using Synaptic, where are the install files stored? I'd like to save them for future use. Also, I'm downloading Conky right now to monitor usage.
One of the things I dislike about gnome is the fact that some bugs seem to exist forever, eloquently described here fore example: [URL]. Now, that gnome 3 is there; I am wondering: should I expect that there will much work on the 2.x side? Or will more and more bugs go "fixed with gnome3"? Is this a realistic thought?
Since open office is now bought by oracle I am confused about the state of the latest version of OO version 3.2 I think. Would it be legal to install that version on a computer. Oracle perhaps made a bummer with this. The real dev community is thrown out and we are again looking at corporate greed taking precedence for their own profit rather than development of technology. I have high hopes from libre office but then one more open source product (it was not sun's to begin with remember) being swallowed by a corporate.
It states there could be changes in role of system adminstrators. If this is going to happen, Being a system admin what are the skill sets do I have to develop ?
Can anyone tell me some current and future threats to the authentication methods used in Linux system. Modules like PAM(Pluggable authentication method), SASL, Kerberos, Shared secrets, shared passwords etc.
I am trying to install Suse linux 10.3 image on to an HP blade via HP CMU. The node gets imaged successfully, but the certain files/directories have a future date timestamped to it. While the server date is correct.

I just set up an VPS with ubuntu. I made a user1 and gave it ownership
Code: chown -R user1 /home/www
This user also have been given all the root privileges (I know it is not recommended!)
The problem is that each time I make new site, and user1 wants to upload (through ftp) files to /home/www/newsite I need to redo the the above command in order to be enable user1 to upload. Not only this, I need to rework permissions (744 for folders and 644 for files), otherwise the newsite throws permission errors message.
