I have a newly installed CentOS 5.4 which is having shutdown problem, if I try "shutdown -h now", the machine will poweroff then reboot instead of poweroff completely. how to debug this problem?
Hardware: Gigabyte G31M-ES2L, 4G RAM, Sil 3112A PCI SATA card, 6 SATA disks and one IDE disk. I have disabled all power on options in BIOS. Software: CentOS 5.4, software RAID, samba
I have a RHEL 5.4 server that randomly reboots.The hardware is entirely Intel.12 GB RAMIntel RAID5Anyone else experience this issue?Grasping at strawsIt is a new server, (3months old), and has been having this issue ever since the initial installation
I have used ubuntu 8.04 in a dual boot system together with windows xp and wanted to upgrade to ubuntu 10.04.
Since the upgrade did not work (the usr partition was to small and I couldn't make it big enough) I downloaded the ubuntu-10.04-desktop-i386 edition and tried to install it.
Everything worked find during the installation process but when I tried to start ubuntu I could only see the ubuntu desktop for a second and then the computer began to reboot.
Then I thought that I can solve this problem by installing ubuntu 8.04.4 again and trying to upgrade to ubuntu 10.04.
After the installation I could start ubuntu 8.04.4 without problems but after upgrading to ubuntu 10.04 the same problem occurs again: ubuntu 10.04 causes the computer to reboot every time I try to start ubuntu.
I am fairly new to linux.We have a machine running CentOS 4.4 and sometimes the machine has to be rebooted. Each time after the reboot, I have to SSH in and manually restart one of our application. I have been reading about doing this online and I am a little confuse.Seems like there are multiple possibilities for starting things up. My finding suggest using the inittab file. Then my question is what runlevel do I pass in? Should I use runlevel 1, 2, 3, or 5? Once the runlevel is determine, then how should I name my startup script? I know to use "S" but what number should I give it? Or, another way to approach this is to put my autostart script in the /etc/rc.local file?
I received a new Cyberpower CP1000PFCLCD UPS today. I let it charge for about 6 hours.My server is a former desktop PC with the following specs:MSI MotherboardAMD Athlon XP 2000+ CPU768 MB DDR RAMDual 80 GB HDD running RAID 1 (Disk Mirroring)After shutting the server, router, and backup drive down and plugging in the UPS, I did the UNPLUG test where you unplug the UPS to see if everything stays on.My Router and Backup disk both stayed powered on, but the Server immediately rebooted.Does anybody have any ideas how I can fix the server rebooting problem? It should be staying on just as everything else.
Last night I rebooted my desktop and it failed as in it just kept resetting after the bios post...so I changed my boot drive which gave me a "no bootable drive found" error(this confirms hdd fault) thee I booted a live cd and checked my partitions
They are as follows sda1 - boot(ntfs) sda2 - windows(ntfs) sda3 - swap sda4 - ubuntu(ext4)
I tried to mount sda4 to reinstall grub but it failed...says the partition is corrupt sda2 has no problems and I made a backup for it now the problem is how do I perform a disk check on sda4 and how do I get my system up and running again? I dont want to reinstall!
I've found a workaround, but the workaround doesn't make any sense to me.I suspect I am running into a bug of some sort.I've tried to search for a solution, but the search terms are too broad and I can't seem to find anything useful.I have a CentOS 5.5 system that I've set up Virtualization on (presumably Xen, right?). I have a RHEL 5.4 Guest OS using "Full Virtualization" method.When I was installing the RHEL guest, the entire server rebooted just as the RHEL guest was booting for the first time.Thinking that odd, but coincidental, I just let the Host server reboot and then started up the RHEL Guest again.The reboot happened again and in the same spot! When I say the server rebooted, I mean black screen...pause...bios screen.I finally managed to get the RHEL Guest booted by removing the DVD that I had in the DVD drive and disconnecting it from the Guest OS in VMM. Very, very odd. I can reproduce this behavior by simply booting a Guest OS with a DVD in the drive (so far I've tried only RHEL guests).
The reboot happens at the same place in the Guest boot process. It's when RHEL starts the UDEV script. Actually, a few seconds after the RHEL system displays "Starting udev" message. I've looked in both the CentOS and RHEL messages log and found nothing.It's not a huge deal at this moment, but I will be sending these servers out into the field and I can't control what the end users of these systems put in the DVD drives.
Has anyone got any pointers on how to get 11.3 installed on a Dell Poweredge 6800 server? System starts to boot from Linux DVD, the screen goes screwy and then the system reboots.
The problem is that when the computer starts up/reboots it doesn't "Unlock the system keyring"(I think that's what it said).
When I try and attempt to connect to the computer it asks for the VNC password(as per normal) but fails to connect after that.
The reason is that the Ubuntu computer prompts for the user's password to unlock the system(locally).
What I want is to be able to turn on the computer without having to worry about entering the password. I've had it running fine on 8.04 yet the newer version seems to be annoying :s
The system is set to automatically login on startup too.
I've tried this: "delete the keyring folder under /home/XXXX/.gnome2" then setup remote desktop again. But that hasn't worked either. I still have to enter the password to a keyring
I just installed 5.6 using the x86_64 netinstall - all appeared to go well, albeit a little slowly. At the end of the install i rebooted the machine but CentOS won't load. If I select the CentOS option from grub (only other option is 'other') the machine instantly reboots.
Only options selected for install where 'server' and 'server gui'.
Editing the CentOS options shows the following but I've no idea whether this is correct or not (assume it is):
I have several systems experiencing this issue, but the "worst case" system at the moment is a system where there are 2 dual-port PCI-X e1000 cards, and two on-board e1000e PCI-express card.What happens is maddening. If the /etc/sysconfig/hwconf is removed, and kudzu is not run, and the 6 interfaces each have a corresponding script:
Now what happens defies explanation. The only way I can be sure to make the e1000e first-listed-in-pci-order e1000e device always eth0 is to remake the initrd and add e1000e to the initrd.If I do not do that, eth0 might be the onboard night, it can also be the first port on either of the dual port cards.So eth0, eth2 and eth4 all take turns being eth0. This was not an issue in the EL-5.1 timeframe. This is certainly new to the EL-5.2 timeframe and thus far is not possible to control because the system does not load eth0's driver alias in order, and the enumeration of the PCI devices causes what seems to be random labeling of the first interface.
This is a particular problem in that identical hardware systems will come up with different eth0 interfaces , and on a single system, without the /etc/sysconfig/hwconf (which calls "eth0" something different from what was originally in the /etc/sysconfig/network-scripts/ifcfg-eth0 HWADDR directive).I need as little auto-magic as possible, I can live with PCI-bus order and driver load order is the order ethernet devices appear in, I cannot use the software in a state where what is "eth0" is randomly determined and the only way I can nail it down is to run kudzu, generate a hwconf AND brand the network interfaces in the network-scripts with HWADDR. I've been using EL since 6.2 and this is the first time I've ever encountered a situation where the enumeration rules (which are ancient at this point) over-ridden by something.
Version-Release number of selected component (if applicable): EL-5.2 series.The random enumeration of PCI devices and the subsequent assigning of eth0 to a random NIC is not on every reboot, and does not seem tied to a power off scenario vs a simple reset or warm reboot. Over the course of 0 reboots , eth0 should have moved between 2-3 times.Packages that seem relevant.
I have an old PC in my basement that I decided to load Ubuntu onto a few months ago. I ran version 9 for a while and then recently upgraded to10.04.Unfortunately, I've been having issues with intermittent system crashes using both versions. Sometimes the computer will work fine for hours and other times it will crash 20 seconds after startup. I'll be able to provide much more information tonight when I get home but for now I wanted to plant the seed in the forum and see if anyone has any ideas.The computer will be working fine and then all of a sudden the screen will go black and then start blinking, switching between a blank screen and a blank screen with a bunch of tiny white squares/lines. When I restart, things seem okay again.
I am running the Nvidia driver. My system freezes randomly. I've had to reboot my system over 5 times today alone. When it freezes, everything is frozen, even the second hand on the analogue clock. One more issue, and I'm not sure if it's related, my stupid screen goes black after 5 minutes of no typing or mouse movement. This never happended when I first installed it. The issue just started within the last 3 weeks. Kpackage Kit is hidden. I was using it to do my automatic updates. Now I just use yum. between the time I first installed Fedora 12 and now, something has happened to my build to cause these issues.
I recently re-installed ubuntu to fix my freezing problem, but with no success. disc has no errors. I cleaned the disc and the cd drive, the cd burner has a problem installing while the dvd drive does fine. The computer is a HP Visualize X-class workstation with dual 1000mhz pentium 3s, 2 gigs ecc ram and a ATI AllinWonder 9700 pro @ 2x agp(wish was higher), on-board sound. So my problems are:
1) It randomly freezes within 24 hours regardless of who is logged in or if effects are on or what the load is. mouse is frozen too, completely unresponsive even ctrl alt f1.
2) My sound is screwy. its supported by alsa but i have to play with the volume to get sound and lots of times there are audio errors, it sounds like its robo-trippin. I have tried the sound guide.
3) Desktop effects only work with the user that logs in first. If I try to activate them when I switch users it searches for drivers then says it cant be enabled. not a priority.
Window xp works okay but the graphics drivers are giving me problems so i decide to do a dual boot.
I think I am going to put in a different video card. maybe its not all there, it got hot once when the fan died, put in a replacement and it worked but i see lines moving down the screen when there are blacks.
My Plantronics headset is detected randomly by the system, I've been searching for hours without solution, however i finally got to thinking that there may be a problem with snd-usb-audio code...
I'm at a loss in trying to debug a problem I have with my media centre. Basically I'm getting random system hangs and when I say hang I mean proper hang - processor stops dead. No animation, not network connectivity, no keyboard/mouse response, nothing. As for it being random - it has happened during movie playback, during idle, after being up a short time, or a long time, it doesn't matter, so it can happen any time really. The logs show nothing suspect, except they just stop and there is nothing common between the logs of two failures. It happens on both my 'old' ubuntu 9.04 partition and on my new 10.04 partition.
I noticed that sometimes my Linux server will randomly start to lag really badly, to the point where even a http request takes forever. It is an Intel Core2Quad with 8GB of ram running FC9. This is my "Everything" server so it does file, email, DNS, web (for local stuff only), VMs and so on. There are about 5-6 VMs running on it at any given time. I manage it through a VNC session and have some SSH consoles within that session. This way if I reboot my PC I don't lose all my SSH consoles. If I need to SSH to any server I do it from there. I treat it kinda like a terminal server to some extent.
When this slowdown happens, top is not really useful because I also do F@H so that will always be to the top, but it's low priority. The VMs are also always near the top. This does not change whether it's slow or not, so when it's slow, I have nothing to go by on how to troubleshoot. The load does seem to skyrocket though. Right now it's doing the slowdown thing and it's at 8.09. Normally it's at around 3 which imo is good as it it's under 4. I have 4 cores so anything more than 4 means it's queuing. At least that's how I understand it. This is the output of top:

My Ubuntu Karmic running system experiences random lockups. There is no pattern in when it will happen, it can go for days without one, or happen every couple hours. Only thing I can notice is that it happens most often when I run Firefox, but when it happens, it happens regardless of me having Firefox open on a website with lots of Flash content or not. When the lockup happens, I cannot move the mouse - the led light on my mouse shuts off, I can't move the cursor, the whole UI becomes unrensponsive, there is no blinking lights on the keyboard, REISUB does not work, only hitting the reset button on my case helps. After reboot, there are no indications of errors in any of the logs that I can see.I have ran memtest for 24 hours, and it completed without errors.

Whenever I'm browsing the web on one of my natty machines, I'm subject to periodic reboots that leave nothing in the syslog. Here's the two constants I've discovered thus far.
It only happens when I'm using a browser (plugin?). It doesn't matter whether I'm in Chromium or Firefox. It doesn't matter whether I use Unity or Gnome 2. This happens every 2-3 days from what I can tell. This problem is not power related because I've tested it with and without an UPS present.
The computer does a full reboot without any shutdown procedure.
The configuration of this computer is as follows: Intel i3 2100 ECS H67 Dual Nic Haupaugge Dual ATSC Tuner MDADM RAID 10 8GB 1333MHz (MemTested)
The browser plugins are as follows: Flash 10.3r181 VLC Multimedia Plugin (compatible Totem 2.32.0) Windows Media Player Plug-in 10 (compatible; Totem) DivX Web Player version 1.4.0.233 QuickTime Plug-in 7.6.6
I m newbie in Linux. i am using fedora 13, kernel release: Linux 2.6.33.6-147.fc13.x86_64 and my graphics card is nvidia g-force 8400 GS. nvidia driver version is 195.36.31.
now my problem is when i run any video file in any media player, my system just freezes...and only way to get rid that is system reset !!! and it get freezed randomly, sometimes system works fine without halting!! i update my kmod-nvidia and kernel but the problem has not been solved!!
OS: CentOS 5.3 Enterprise Server Red Hat Nash Version 5.1.19.6
I need to find a command-line program to randomly change my MAC address. I know on Ubuntu there is a program called 'macchanger'. And on Windows another one called 'macshift'. I just can't find one for CentOS 5.3 Enterprise Edition.
I've recently installed Fedora 14 (x86_64) on my Alienware m15x laptop which has a NVIDIA GTX 260m onboard. Now I have followed leigh123linux's guide to installing those drivers on F14. The installation is a success and everything seems to be in working order, until the system randomly logs the user out and/or restarts the session with no warning. The screen goes black and the nvidia logo appears and then its back to the login screen again. This can happen many times with no apparent stop insight. This does not happen with the default F14 drivers that come with the installation, I have tried several re installations of the Fedora OS and several re installations of the NVIDIA driver, i still have the same problems.
I have some trouble with my hp workstation xw4400 with an ATI FireGL 3300 and the X-Server. There was no problem with the graphical install routine and the graphical boot works fine. But when the system changes into the login-screen, then it results in a black screen and a more or less frozen system.
I am an old days RH release user(from 6.x) and just switching back from Debian/Ubuntu to CentOS on some servers, but I can not understand the kernel update strategy currently enabled in CentOS.There are two boxes, with almost identical installation, but recently there was an auto update of kernel on one box. This auto update also seems to issue an auto reboot on the machine, which is unacceptable on server machines.
I am trying to do a basic install of CentOS 5.4 on my embedded computer. It is a Linutop 2 system with a AMD Geode 800MHz CPU and 512Mb Ram. Have installed an IBM 40Gb 2.5" HD for OS storage. I am doing the install procedure in text mode. Everything goes as planned until I get to the package selection.
1. Booting from (i386) DVD with "linux text" parameter. 2. Skipping media check. 3. Selecting "English" install language. 4. Selecting "DK-latin1" as keyboard layout. 5. Selecting "Remove all partitions and create default layout" and selecting "no" to modifying partition layout. 6. Selecting "yes" to configure "eth0" and mark to enable "IPv4" on boot. 7. Selecting DHCP for IP configuration and Manual host name. 8. Setting time zone to "Europe/Copenhagen". 9. Setting root password to a 16 digit alphanumeric pass-phrase. 10. De-selecting "Desktop - Gnome" (no other entries selected).

have all ways been hiding in the background read not say a thinglets start well i look after 2 dell poweredge 2650 with 12 gig ram installed servers has been running fine onwell i though it was time to upgrade to 5 all went fine till reboot Memory for crash kernel (0x to 0x) not within permissible range ! well what i have been reading this is the norm for now What is mean by ignore it? LoLwell so i did the system keeps boot till i get to this linesbin/mingetty: /sbin/mingetty: cannot execute binary file alot, and it shows. INIT: Id "5" respawning too fast: disabled for 5 minutes ...so maybe its a memory issue so took 8 gig out left 4 in the system now it reboot alls good with only 4 gig of ram installed so is there a way to fix it to use all the ram can i get the system boot on 4 gig and then add the 8gig later on
We have 2 applications set as S96 and S98 at rc3.d and rc5.d simultaneously. Both applications create a system V shared memory segment by calling shmget.If the system boot at runlevel 5, both applications can obtain their shared memory segment id correctly, i.e. 98305 and 131074 individually. While there is a root owned segment id 32768 takes first seat on the list. This is the id list:
Is it possible to list/find/compare the program versions on a Centos system, against Redhat/Centos Errata/Security/Bug lists? Sort of looking for a way to make sure that all the packages on a system are ok, and not a security risk-- Without having to update every package. A pseudo code, in my mind is:
