CentOS 5 :: Server Randomly Shutdown At Certain Time?
Jun 11, 2009
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:

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

Ubuntu will randomly pop up the shutdown menu and then shutdown.It seems to happen when im in firefox and typing and it has been difficult to replicate. I dont think it is a temp issue since watch sensors shows temmp of 40-50C. Someimtes it happens every minute someimtes i can go 10min without it happening.

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.

when I restart my computer I have no sound what so ever, the volume icon is just 3 dashes, and if I try to shutdown it brings me to the login screen, with no way to shut down except for holding down the power button.I'm using an Acer Aspire 4530.I didn't have this problem with Ubuntu 9.10.

I use centro 5 to run a game server with the command ./srcds_run quit -game cstrike -nocrashdialog +map de_dust2 +maxplayers 36 +ip 95.154.192.34 +port 27015 -tickrate 67
which then starts a 36 slot CSS game server but as soon as i close putty it ends now i tried nohub ./srcds_run quit -game cstrike -nocrashdialog +map de_dust2 +maxplayers 36 +ip 95.154.192.34 +port 27015 -tickrate 67 and ./srcds_run quit -game cstrike -nocrashdialog +map de_dust2 +maxplayers 36 +ip 95.154.192.34 +port 27015 -tickrate 67 > srcds.log 2>&1 &
i'm woundering if it something to do with centro 5 why nohub isn't working becouse it works for others either

I have just installed Lucid i386 on an intel Core2Duo. Everything seems to be OK but about a third of the times I boot the system the following happen:
1) aplay -l reports no soundcards found and therefore I have no sound whatsoever
2) I cannot mount any USB Flash drives or DVD discs and I keep getting "Not authorized" error messages plugging them in.
3) The system won't reboot/shutdown by the gnome applet. Instead, it will drop back to the login screen asking my login. Furthermore, it won't even shutdown from there! Only a poweroff or reboot from command line can work.
4) The gnome applet "Indicator applet session" only shows "Log out, Restart, Shutdown". Suspend and Hibernate options are missing.
Furthermore, it seems that I am the only one who has these issues. My sound card is an onboard HDA Intel although this seems to be that something else dies taking some major subsystems down with it. Any ideas?
/proc/asound/cards shows:
0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfe028000 irq 23
but: aplay -l
aplay: device_list:223: no soundcards found...

I have built a Centos 5.3 server for a friend of mine that is being used as a NAS server. The server has 4 1TB drives in a RAID 5 configuration and a dedicated non raid system drive for the OS. My friend isnt very Linux literate so I need this bow to be relatively simple. I have worked most of it out but have a question with regards to remote reboot.
I need to be able to shut this device down through the power switch without human intervention (at the moment when the power switch is pushed the server asks to confirm shutdown) the server wont have a Monitor connected so this isn't practical. Is it possible to use the power switch to do an clean, immediate shutdown?
The other option is shutdown through a web page is this something that has been done before? I know he can do it through terminal by issuing a shutdown now command but as I said this guy wants something simple. I don't really want to explain everytime he needs to shut the Server down how to do it if he can just do it via a website or even with the power button.

I'm trying to reboot the server (shutdown -r now).But it seems like nothing happened.
When I try "shutdown -c", the system prompts "shutdown: cannot find pid of running shutdown."

I have installed a cluster computer with 10 nodes . The manufacturer is HP . All nodes and the master node have redhat enterprise linux installed in them . When I shutdown the nodes from the master terminal using "shutdown -h now" they get shutdown . But they dont get completely turned off . This issue bothers me when the power supply is given , all nodes boot up simultaneously generating a huge heat .
Thing to note : When we shutdown our PC they get completely turned off . When the power supply is given , a press on the Power On button is required to boot the system. But , why does it not happpen in the case of cluster? Is there any other way of completely turning off the nodes from the master terminal ?

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 have two boxes that were originally used as workstations at a school - they upgraded and sold these.The two boxes are identical parts - Lenovo NetVista M42. I installed 5.3, installed RPMforge per the wiki instructions, did a yum -y update && shutdown -h now.The next day I turned the machine on and installed the UT2004 dedicated server. After a few hours I tried logging in via SSH - I could enter my user and password, but could not get farther. I rebooted the server. After another day the same thing happened. I moved the disk from the first box to the second and moved /etc/sysconfig/network-scripts/ifcfg-eth0.bak to ifcfg-eth0 but retaining the correct MAC address.
During this transition where the server "locks up" some things work and others do not. For example, if I type ping 4.2.2.2, wait 10 minutes and CTRL+C it looks like this (note the time of 0ms).

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.

I am installing CentOS 5.5 64 bit on a HP ProLiant server. The server has a configuration of 2 TB(500x4) HDD and 8 GB RAM. RAID 5 is enabled and mirroring is also going on. I made 7 partitions. Those are:
/boot - 200MB
/ - 80GB
Swap - 20GB
/usr - 100GB
[code]...
The problem i am facing is it takes too much time to format 100GB partitions while installing packages (during installation).

I'm running a CentOS 5.2 vm on a W2K8 hyper-v core server. The problem I have is that when I reboot, the system time always resets itself to 6:00 am in the morning. I tried the /sbin/hwclock --systohc command but it hasn't taken hold.

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 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.

I have never had the packaged vsftpd start with the ssl_enable option set to YES. The mysql on those servers works just fine with SSL enabled. After reading there seems to be a different package available on rh5 repo. This server shows up to date with 2.0.5-12.el5_3.1. The rh5 list shows 2.0.5-16_el5 per this:[URL].. My question is, is there a set lead time till adoption of current RH packages or is just random? I have to have SSL_ftp running and didn't want to step out of the repo lists if possible.

I have written simple application in cpp which listens on port 8080. But when I start the application and check the port it is listening on (using netstat -nap), I can see that the application is listening on port which is > 30000.
This port number keeps on changing if I re-run the application.Please let us know if I have to do any kind of a seeting so that application starts listening on 8080 port.I am using CentOS 5.5 (I tried same on CentOs 5.2)

I restored a whole filesystem from a backup using rdiff-backup and made it bootable from a modified CentOS 5 CD ROM.All works well except all the files have SeLinux context ofroot:object_r:file_t:s0I tried rebooting with .autorelable and it seems to take no time and reboots immediately after starting. After, there is no change in the contexts of the files.I also tried fixfiles and restorecon with and without selinux enabled and in all cases it takes no time and returns no error code i.e. it does nothing. Nothing in the system log either.

When I installed CentOS, I forgot to modify the settings of Network Time Protocol. I need to do the following:
1. Enable Network Time Protocol.
2. Add a new ntp server to the list.
How I can do this after the installation. Is there an utility to handle this? or do I need to modify any files manually?

We have a production web site running apache 2.2.3 across several web servers. we also have a major problem with SPAM comments right now. our method of identifying valid IPs (whether by external clients/customers, or internal personnel) vs SPAM'ers is not ideal - its prone to erroneously labeling legit IP's as targets to be blacklisted.
What we need is.. a way to see how much distinct request traffic is coming from any given IP address to the site in real time (or very near realtime). Essentially we want to see in some graphic/chart way requests per sec to apache / per ip sorted by requests per sec.Would nTop do this? I've only used this in a limited form at a branch office, not on a production web server.

I have a CentOS5 server with a 1tb hard drive.There is only 80gb of data on that huge drive and now I want to make a bare metal recovery backup using AcronisMy question is, how can I estimate the amount of time the backup will take and the size of the image file? Is it based on the size of my drive or is it based on the amount of data on the drive?
