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?
I've got fedora 11 set up to use network time protocol to sync my laptop's date & time when I'm on-line. The question is simple really, I've added a local universality's time server (what is public) and it's live. but it's added to the end of the default time servers what come with fedora. How do I get fedora to just use the local time server, is it a case of removing the default time servers for fedora, but there is a box what says advanced options which are. sync system clock before starting service ???? & use Local time source (( is that the same as the local ntp server that I've got set up ))Hope some body can help me with the network time protocol part of Date/Time settings.

I've been testing a PDC with samba and LDAP these days with the following unsolved issue. 1. I can add the client PC (Windows XP SP3) with the Domain Admin user (Manager) from the client PC, but when i try to add a user I get this message "The trust relationship between this workstation and primary domain failed", so as it can be added later I ignored this message and choose 'close' and reboot the PC. 2. Since the login screen is showed, the message 'Duplicate name exists on the network' appears. So I try to log on with a valid domain username and password after pressing ctrl+alt+del and get the error message: "System cannot log you on because domain rmprb is not available"

I have Ubuntu Server 9.10 up and running as my file server. However, it sits amongst other PCs running XP Pro and Network Printers (e.g. Xerox Docuprint C2535A) on the network. My question is whether there is a way of adding the Xerox printer to the Ubuntu Server so that other PCs will send print jobs through the server. I think the printer is windows-based printer. Is it possible to do this? or are there any other options that you may be able to share with me?

View 2 Replies View RelatedI am administrating a server with CentOS installed. It came with qmail and courier-imap preinstalled, and Plesk.I need to manually add email accounts outside of Plesk, because my 1-domain Plesk license only allows the creation of one email address (yes, it sucks).
When I say add email account I mean creating a new email address, have email for that address be stored in its maildir, and have a corresponding imap (and hipefully also pop3) account that will be able to read that mail. All this with virtual domains.I've already found out how to create the new email addresses for qmail, so that email for the new email address is being delivered correctly. Now I need to create the imap/pop3 accounts for courier.
For the qmail part, I create a folder in in /var/qmail/mailnames/virtualdomain.org/username and a maildir called Maildir inside it. This is how the first mail address was created by Plesk and i'd like to maintain the same structure. As I've said, the qmail part is already working, I need to get the courier-imap part to work. Ideally, it should accept login with both short (i.e. myuser) and long (i.e. myuser@virtualdomain.org) user names.
Currently the only authentication module that is enabled in courier-imap is authpsa, which is Plesk's authentication module.in order to add more authentication modules, do I just need to add them to the authentication module list in /etc/courierimap/imapd, or do I need to reinstall courier-imap with support for such authentication modules? I thought I would only need to add them to the list, but I've noticed that the /usr/lib/courier-imap/authlib/ folder only contains a binary called "authpsa". Does that mean that other authentication modules are not even installed? If so, can I install them without reinstalling courier?
The second question is, what would be the most recommended authentication module that would make it easiest to create new email addresses/accounts from the command line? I need to be able to write a shell scripts capable of creating a new email address with all that is needed, and I'd like to keep this script as simple as possible, so for example I'd avoid mysql-based authentication as it sounds rather complicated. And the last question is, if I do need to reinstall courier-imap, how can I install a package without recompiling it? Will my one existing mailbox keep working?
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).

View 4 Replies View RelatedI 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

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.

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.
View 1 Replies View RelatedI 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.
