CentOS 5 Server :: Time Sync Error ?
Nov 1, 2010I 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?

Server :: Unifying Permissions Between Two Servers - CentOS - Webmin/CentOs - Cpanel - And Rsync
Jan 1, 2010I have two servers, both running CentOS, but one running Cpanel as the control panel and the other running Webmin.
I would like to sync the web folders using rsync. However, when I sync the files from the Cpanel host the permissions look as follows:
Code:
But that doesn't work on the Webmin server which needs the following:
Code:
It seems the Cpanel install has the group as 'nobody' whilst webmin has it the same as the file owner. I can fix this by running:
Code:
But as the file transfers will be frequent, I don't want the files to be inaccessible until chown is run.
So, what I really want to know is - how can I change things on the 'webmin' server so that files with ownership owner:nobody will run?
CentOS 5 Server :: Building VMWare Virtual Machines From CentOS Mail Servers?
Oct 12, 2010I have a few mail servers, a mail log server and a web server running on Centos 5. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves.
I have already installed VMWare Server 2.0 I have a few questions: How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program? How do I actually do this cloning? Is there a tutorial on how to do this?

Apr 12, 2011I'm trying to download some SRPMS from CentOS 5.6 tree, but it seems that a lot of mirrors are not yet synced for the SRPMS directory.
I barely see the repodata and xml files inside it, but no SRPMS at all.
Is it a deliberate action to provide faster distribution of the 5.6 install tree or someone forgive to give the last rsync?

Aug 4, 2009I 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.

View 1 Replies View RelatedCentOS 5 :: Create Channels To Sync Yum Repos And Smart Channels?
Jun 24, 2010I've installed RPMforge and Smart Package Manager.
I had to create my own Centos 5.5 channels to sync yum repos and smart channels.
Here's the Centos 5.5 channel file for Smart:
Just shut Smart PM down, copy this file into /etc/smart/channels, and restart smart.
Smart should then detect the new channels (repos) for Centos 5.5
Update your channels in Smart, and you should then have yum repos and smart channels both in sync, looking at the same set of packages.
Copy this to CentOS-Base.channel, and add it to the /etc/smart/channels directory.

CentOS 5 :: Time Display Is 12 Hours Out?
Apr 11, 2009I have the bar at the top configured to display the time but it is displaying 12 hours out.For example, it's now 16:49 but the time is displaying as 06:49. If I click on Adjust Date & Time it has the correct time in there and it is configured to display 24-hour format and is in the correct time zone. If I switch to 12-hour format it displays 6:49 AM which is clearly incorrect.I can't fix it because it thinks the time is correct when I try to change it.

View 2 Replies View RelatedCentOS 5 :: New Server Freezes In Time
Oct 30, 2009I 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).

Example: I fire up Amarok, then start my VirtualBox Windows machine, and I get an error from Virtualbox saying sound can not be initiated for the session.Same with mplayer, or any other sound app, while another app using sound is open, causes an error saying sound can't be used.
