Prerequisite: This tutorial covers adding a new disk drive to your linux computer. First it is assumed that the hard drive was physically added to your system.
IDE based systems, can support two drives on each ribbon cable. The cable is attached to either the Primary or Secondary IDE controller. A “jumper” is pressed onto two pins (thus connecting the two pins) on the drive to define the drive as a “Master” or a “Slave” drive. Each cable can support one master and one slave drive. Typically new desktop systems have one hard drive connected as a Master on the Primary controller and one CD-Rom on the second cable configured as a master. [...]
The file that actually handles WHM > DNS Functions > Nameserver IPs area is at /var/cpanel/nameserverips.yaml location.
If you want this to be changed, you’d want to make a backup of that file first and then modify it:
cd /var/cpanel cp nameserverips.yaml nameserverips.yaml.back nano nameserverips.yaml

If you are new to linux you probably will wonder how to change the hostname of your computer or server. (A hostname is the unique name by which a network attached device is known on a network.) If you enter the wrong hostname during the installation, and you need to change the hostname, here is the solution:-
- Edit file /etc/sysconfig/network using your favourite editor. In my case is nano. So i’ll enter nano /etc/sysconfig/network
- Look for HOSTNAME=xxxxxx
- Change the xxxx to the name you wish to set for your computer. (ex: HOSTNAME=wiredgorilla.com)
- Save the file and restart the xinetd service. (ex: type service xinetd restart in your shell)
- Done! You have just changed your hostname in Linux platform

Plesk Login prompt Issue
A strange login prompt is presented when trying to view a website on a windows plesk account , even though the website directory is not password protected.
This issue results from the anonymous account password used to deliver the site to public web viewers , getting out of sync with the main account password. To fix, just re sync anonymous password by issuing the following command in the run dialog:
"%plesk_bin%\websrvmng.exe " --update-anon-password --domain-name=yourdomain.com
When running a ‘yum update’ under CentOS, there are certain packages you may be running which you wish to remain static, or which can potentially cause errors with the update eg. Samba.
In these situations it is useful to force yum to exclude certain packages from being updated under CentOS.
Yum uses a configuration file located at <
If you wish to exclude packages you need to define a list for exclusion from updates or installs. This should be a space separated list. (Shell globs using wildcards * and ?) are allowed).
If rpm / yum command hangs during operations or you see error messages – it means your rpm database corrupted. /var/lib/rpm/ stores rpm database just delete the same and rebuild rpm database:
Command to rebuild rpm database
rm -f /var/lib/rpm/__db*
rpm --rebuilddb -v -v
