Red Hat / Fedora :: Time Randomly Changes On Server?
Feb 15, 2011
I have Dovecot installed that constantly "commits suicide" due toe constant time changes on my server.But I don't have any NTPD or anything running.. If I do a Code: watch date it updates the screen every 2 seconds, and you can clearly see the time flip back a few seconds, and then go back to the correct time.. Sometimes it goes back a few minutes, and back to normal..
I literally did this 10 seconds ago..
Code: [root ~]# date

2 times now our server has randomly shut down. Completely powered off as if the power cable was pulled or something. Both around the same time. 7:30ish. Once was on Friday June 5th, then last night, Wednesday June 10th.
Here is the log from last nights crash/shutdown:

My time keeps getting thrown off by about 15 minutes. It corrects itself randomly but then goes back! Not sure yet if it's decrementing slowly or if it takes 15 off all at once.ntpdate ntp.ubuntu.com puts it back, output is:Code:15 Jul 08:09:29 ntpdate[6157]: step time server 91.189.94.4 offset 1056.199059 secCurious what the "offset" means. Is there a way to ensure it keeps constant time without having to do it manually?

I think this might be related to the changes to using udev or DeviceKit. It started when I was running the beta versions of F12. Then it crept into Debian Sid. And my Arch Testing and Gentoo also suffer from the same.
What happens is that I'll be working along. Then when I press any key it is as if the SHIFT key is pressed. When I press CAPSLOCK, some of the keys react as they would normally. This never lasts for more than 5 minutes. And seems to happen infrequently. I say seems because there are the times I am at work and it could be that the same thing is happening only there is no one on the keyboard.
The reason I pick out udev/DeviceKit is that when it used to happen to F12 beta, the other distros had not yet made the move. So back then it was only a F12 issue. Now it is happening across the board. And only started recently.

On my computer, I mount at boot time through the /etc/fstab some shares.I was working flawlessly on 9.04 and previous version.Since 9.10 version, it sometime fails to mount the share and I need to run PHP Code:sudo mount -a to get my mount shared mounted. (the command "mount -a" always work).

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 trying to synchronize the time of a PC using NTP using a server on LAN. Both the PCs do not have internet. I have made changes to the /etc/ntp.conf file of both the server and client . But still on rebooting is shows Synchronizing with time server failed. I am attaching the ntp.conf file of both server and client.

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 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'm using FC12 with kde and cannot update the system time using the gui. The error is :Error unable to contact time server. How do i get it to work for the rest of the family who do not want to mess aboutcli mode?This does work from the terminal:ntpdate -u ntp.exnet.com so client software is present and correct leaving me at a loss.

I`m using Ubuntu Server 10.10. The system randomly restarts each day.Here are the logs: http://paste2.org/p/1499309Everything seems normal except that UDP: short packet thingy but even Google didn`t help me to find what`s thatBy the way, I think reboots started after I configured this PC as a gateway between internet and my local network

I'm in somewhat of a sticky situation. ssh has just randomly stopped working on my server after a power failure. Everything else that doesn't rely on ssh is still working fine though. It can still receive mail and everything, just no ssh.Background on the server, running debian etch on a PPC machine.ssh is (supposed to be) running on port 2000. Even if I am physically logged into the machine I can't log in with ssh -p 2000 user@127.0.0.1.
I can ssh to and from any other machine on my network (the server can even ssh into another machine). So it isn't my network causing issues.It seems like the port 2000 is completely closed, if nmap the server's IP address I get PORT STATE SERVICE
25/tcp open smtp
80/tcp open http
110/tcp open pop3

I messed up the first installation of Fedora on my server. My setup is as follows: Fedora and Gnome - NFS system, No dual boot (Windows or anything) Fedora ISO DVD downloaded No kickstart or other tools. how to set this up, from the time I insert the disk and have it boot up (configged already to boot from it). I know how to wipe it clean at intall time. Is that the root directory? And, is /boot the actual boot directory? I'm just having a hard time uderstanding that. As I said, I just want a quick itemized list, step 1, step 2, etc, from partitioning, creating file system, mounting, etc. in the right order.

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.

I have an Ubuntu 11.04 Server set up for my small office whose sole job is to run as a samba file server. The problem is that it randomly hangs. For example, I can connect the clients just fine, however if left idle it tends to take a few moments to work when you try to go back into the shared folder or drive. The client will behave like it is disconnected and is trying to search for the drive only to a few moments later, go right back to normal behavior.
If I ping this server while this is happening my requests will time out for a little while and then just start working. The same thing happens when I try to connect with Putty or through WebMin. One second its unreachable then the next its fine.I have already tried swapping out patch cables (which actually seemed to work for about 2 weeks) and I have patched it to an alternate port on the switch. The only thing I have not done at this time is to change the NIC.All the clients are running Win7 with the exception of two XP machines.Simply put, its like the machine just goes dormant for a while until you ping at it for a while to wake it back up.

I am using Fedora 15 64bit (GNOME 3). Everything is working fine and I'm really enjoying the new GNOME but when I use it for let's say a couple of hours, Gnome get's stuck.I'm able to move my mouse and music keeps on playing, but I can't click anything, drag windows or close a window.When I press ctrl+alt+F2 I can still enter a terminal. (by the way, how is it possible that the gnome-shell command uses 99.4-101% cpu without any noticeable lag on my system and a strong processor?)

I'm running Fedora 13 32-bit on a Samsung NC20 netbook (specifications here: [URL]. Everything works fine, with the exception of media playback via VLC and mplayer. The biggest problem is that the entire OS frequently locks up when exiting full-screen playback in either application, and occasionally locks-up when starting playback via mplayer. Video is also always on top of other windows, regardless of whether the application is configured to be always on top.
The lock-ups are severe enough to warrant powering off the machine, as CTRL+ALT+Fx does nothing. I suspect this is related to the machine's VIA CPU/graphics chipset - I've had problems with them before in other Linux distros, but playback was fine under F12 on the same machine. Because the video windows are always on top, I suspect there's a general issue affecting media playback - hopefully configuration related!
