CentOS 5 :: New Server Freezes In Time
Oct 30, 2009
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 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.

Ever since I installed Ubuntu Natty, from time to time, for no particular reason, the entire computer screen freezes, and I am forced to hold the power button on my laptop to restart things with a hard reset. I cannot explain why it happens.
Such an issue never occurred in any of the past installations and versions of Ubuntu. This is a fresh installation of Natty by the way.
Also, I can currently be running a lot or nothing and it does this. Thus, it does not matter what I am actually doing (ie, what programs I might be running).
It has occurred about 10 times since I freshly installed Natty 6 days ago.

I don't know why but since I upgraded the KDE 4.4 desktop from openSUSE 11.3 to 4.5, the desktop just freezes some times.
If i was listening music, or watching a video I can still hear everything and even move the mouse, but nothing works.
So I switch to TTy1, perform a init 3, then init 5 to restart all the graphic system, and start again. This happens without message, without log, and without clue...
Should I downgrade to 4.4 or this has a Workaround?

I am new to do this. It is my first CentOS install. I burned the 6 ISO's from the site and installed onto a Dell Dimension 8200. At the very end of the graphical install (CD 6, 2 minutes left) it freezes. There is no error message, but the file it freezes on is: Installing Gnome-applet-vm-0.1.2-1.el5 i386 (113KB).

I'm running VNC Server on CentOS5 on a brand new installation, this is for some of my students to use specific software via VNC on their machines from home that they otherwise don't have access to on their Windows machines. This has been working fine on our previous server for a few years but the hardware is now outdated so I have upgraded and put a fresh install of CentOS 5 on. This works fine for about 24 hours and then eventually one of the session ends up freezing where the user then can see everything on their session, the cursor can move but they cant click a single thing.

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).

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'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.

We are having a cluster with couple of disk servers, compute nodes and a head node. Disk server is nfs mounted on all the compute and head nodes.
The problem is that if any of the disk servers hangs, it freezes rest of the cluster too which is dangerous. Ideally, cluster should not care about the hanged server and run without any problem except files from that server is not visible.
Is there any way I could avoid the problem of freezing cluster because of one hanged 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?

I've setup vsftpd correctly and it's running fine with local users (in the same LAN). However, when remote users wanna login to the server, it takes more than 1 minute to get in. Users do can login from remote. It just took too long. (It prompted for the username and password very fast.) Since the server is behind a router, I did configure the port forwarding for TCP 20-21. The centos version is 5.3. The vsftpd is v2.0.5.

I'm dual-booting Vista and Ubuntu. Ubuntu freezes all the time, like every 5 mins so I don't ever use it. I just do a new installation every now and then to see if it fixes itself but it doesn't. It says that the battery has a low capacity, could this be the cause?it only freezes in Vista when I take out the charger, about at the same frequency as in Ubuntu.
