Fedora :: Time Jumps Backwards On Reboot / Stop It?

May 30, 2011

Just installed F15 using preupgrade (from F14) and now, every time I reboot, time jumps backwards 4 hours. If I reboot twice in a row without correcting the time, time will be off by 8 hours. Time zone is set correctly (Eastern Time). "Synchronize date and time over the network" is unchecked.

Since the difference between GMT and Eastern time is 4 hours, there appears to be some confusion over that but I can't find anything in the "Date & Time" app relative to that to try to play with to see if I can correct this. II do remember a similar issue many releases ago but I can't remember how it was dealt with.

Any ideas on how to diagnose and fix this?

Red Hat / Fedora :: System Time Jumps, Applications Crashing?

Oct 17, 2010

I run a mostly untouched CentOS server, nothing is installed except a server app to store data. The server has been crashing lately - after a year of no problems, so I looked into the logs of it and noticed weird discrepancies in the time around the time it crashs. So I started "watch date >> datefile" and this is what happens:

Code: Sun Oct 17 09:52:45 CEST 2010
Sun Oct 17 09:52:47 CEST 2010
Sun Oct 17 09:52:49 CEST 2010

CentOS 5 :: Clock Time Jumps Into The Future (Xen + Ntpd)?

Nov 20, 2009

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.

Ubuntu Multimedia :: Audio Plays Fine, But The Video Jumps And Can't Get A Clean Picture Except For Maybe 15% Of The Time?

Jan 1, 2010

I have 9.04 and I recently "got" a 13.2GB 1080p HD movie. When I try to play it, it's choppy and mosaic like. The audio plays fine, but the video jumps and I can't get a clean picture except for maybe 15% of the time. I have to hold down the spacebar so it plays and pauses very quickly for the video to even proceed. I've updates VLC and Movie Player and I've downloaded many codecs and I can't seem to fix it.EDIT: I can play it in Movie Player without the pixel/mosaic-like effect, but it too is extremely choppy.

Fedora :: Save Setting In Alsamixer - Get 6ch Every Time After Reboot?

Jul 21, 2010

I change the audio channels to 6 in alsamixer by choosing my sound card and change the channels to '6ch'. But this setting is not preserved. I see that after a reboot the channels are again going back to 2ch. I have to manually change everytime to 6ch after each reboot. Is there a way to save the setting in alsamixer so that I will get 6ch everytime after reboot? I am not sure I have explained my problem in a way so that you can understand.

May 26, 2011

I upgraded from fedora 14 to fedora 15 yesterday. I live in India (IST) which is GMT +05:30. Every time I boot, my system clock increases its time by 5 and a half hours. For example, system clock on my machine is now Wednesday May 26,2011 22:44. If I were to reboot now, the time I would get is Thursday May 27, 2011 04:14. How do I correct this?

Fedora Hardware :: Mouse Jumps On Network Activity / What To Do?

May 21, 2010

I'm after fresh install of Fedora x64, did all updates. I have wireless pci card TP-LINK TL-wn510G (Atheros chipset) which was detected correctly.

Everything is working smoothly until I start to download from internet in firefox (or in konqueror - no difference). On increased network activity my mouse cursor starts to lag/jump when moving - it's almost impossible to do anything using mouse when there is file download. On minor traffic, like browsing webpages, I don't notice such behaviour.
I checked if its rather because of hdd activity not the network, but no - when copying big file on hdd everything works fine.
I'm also experiencing huge ssh lag/jitter despite the ping is low.
I fired top when downloading, but there is no process eating cpu in suspicious way.
I have a regular usb mouse.
On the same computer I have installed Win 7 and OpenSuse and nothing like this happens on that systems.

I think there might be a some kind of conflict between wifi card and usb mouse (they share resources) but don't know how to check/repair. Could you please tell me how should I proceed to check what is going on. I haven't modified any hw settings, the installation went w/o any errors.

Ubuntu Installation :: HDD Seems To Stop Working After Some Time

Sep 29, 2010

I recently bought a Shuttle XS-35 Mini-Barebone-PC and filled it with a 2GB Corsair RAM and a 1 TB WD Scorpion Blue Drive.After assembling all the parts I simply wanted to install Ubuntu but it simply doesn't work. However then I had the idea it would be good to kinda get the drive to a completely clean state and used the tools to safely wipe the whole HDD (by writing zeros everywhere as the tool tells me). The tool ran good for around 30 minutes but suddenly the write speed showing in the console window would go down to 0B/s (meaning basically nothing at all I suppose). I tried it 2 more times and it always came to a halt at the 10-20GB mark.

So this lead me to belief that that is also the problem while installing, that my drive doesn't want to wark anymore but rather just sleep a bit.What could be the problem? Is it a hardware error? Is there some linux system setting that could whip my HDD whenever it gets lazy? Did I do something else wrong?

Ubuntu :: Recording Several Desktops And Each Sounds At Same Time / Stop It?

Sep 28, 2010

I'm trying to develop a system that records different desktops at the same time. I have developed a audio-videochat system and I want to be able to record what happens in every room, so my starting idea was:

1) Open a graphic terminal for each room. I have succeeded using vncserver :NumberDisplay.
2) In each terminal, run firefox at each URL. I succeeded too because firefox lets me specify in wich NumberDisplay I want it to be open
3) In each terminal, run recordmydesktop to record. It allows too to specify the NumberDisplay.

My problem now is that it seems that the sound card is "shared", so the sounds recorded in the display 1 includes the sound generated in all others firefox windows. I havnt found an analogy for the sound as the display is for the graphics.

I have thought some ideas but I havnt been able to materialize anyone.
Im tried to create virtual sound cards and specify one for each vncserver, I tried to redirect the sound of each firefox window to one "channel" (read firefox delegates the sound so that might not be an option), I read many things about pulseaudio, jack and several stuff that I just havnt been able to work.

Ubuntu :: How To Stop Disk Check Every Time On Boot Up

Dec 19, 2010

Every time I boot up I have to go through a disk check and then restart, how do I stop it from happening? When the disk checks happening I press escape and it usually says its deleted inode something because it has zero Dtime or some thing similar and also a paragraph of repeated lines saying something like all system files need alsa base.cnfg it will be ignored in a future release then the disk check completes and it restarts and is fine then, also sometimes it says dev/sda5 (my ubuntu partition) was not cleanly unmounted check forces. Is their a way to stop this happening as it ends up taking ages just to login.

Fedora Security :: Backwards Security - Networking ?

Aug 3, 2009

Problem that may require several tools available on Fedora. I don't know if its possible or not.

Given: Surveillance video box based on Fedora & Zoneminder. Internet connection is via a private 10.x.x.x network connection to the local phone company/ISP. That's the only connection available and they are the only ISP in the area. The ISP uses NAT to ultimately provide a routeable IP address, but that only works on outbound initiated traffic.

Problem: How can someone out on the Internet hit this box? i.e Is there any way to rig a method that will ultimately allow a connection initiated from the Internet to see the surveillance video that this box has stored via an http session?

I thought of one idea but don't have the tools to implement it. User sends an email to a server out on the Net somewhere. Surveillance box retrieves mail ever minute. The mail contains the users IP address. Surveillance box sends an outbound packet to that IP address to get NAT functional. The users box then uses that address to hit the box on the private network. The snag with this is that NAT is specific to ports, and I have no sway over the ISP's NAT capability.

Is there any way to push an http session outbound to the waiting end user? i.e. initiate a push of http traffic from the private box to the end user?

OpenSUSE :: System Time Is Always Wrong After Reboot

Jan 6, 2011

Every time I reboot my computer the system time always comes up exactly 10 hours behind where it should be. So if I reboot it at 16:00 it comes up as 06:00.

This has only been happening since I got back from a trip to Australia, where I naturally changed the computer's timezone to match the local one. I'm now back in Central European Time which is 10 hours behind Australia's. This is on opensuse 11.3.

I've used the YAST date and time tool to set the timezone correctly, and /etc/localtime is set correctly:

:~> sha1sum /etc/localtime
b065fae6bda0f0642ca6a52b665768e34a99d213 /etc/localtime
:~> sha1sum /usr/share/zoneinfo/Europe/Berlin
b065fae6bda0f0642ca6a52b665768e34a99d213 /usr/share/zoneinfo/Europe/Berlin

General :: Loose An Hour Every Time Reboot PC?

Aug 8, 2010

I was wondering if any one came across that issue before. Everytime I reboot my PC something (I assume GNOME) reset my system clock to an hour behind what is was the last time. So if a reboot twice in a row that'll be two hours behind and so on. It used to work fine until I had to change my system time backward temporally to overcome and issue with GPG. Since I put it back I get that phenomena. It's like it's adjusting it for the Day light saving everytime a boot. Problem is Japan does not have any day light saving. I run OpenSuse 11.2 with Gnome 2.28.2 as my interface. I'm currently located in Japan GMT+9 not DST. /etc/localtime -> /usr/share/zoneinfo/Asia/Tokyo

I suspect a bug in Gnome or Yast. It's not user specific because the time is already altered even before I log it.
