effect.

You can now run VMware Tools by invoking "/usr/bin/vmware-toolbox-cmd" from the

command line or by invoking "/usr/bin/vmware-toolbox" from the command line

during an X server session.

To enable advanced X features (e.g., guest resolution fit, drag and drop, and

file and text copy/paste), you will need to do one (or more) of the following:

1. Manually start /usr/bin/vmware-user

2. Log out and log back into your desktop session; and,

3. Restart your X session.

To use the vmxnet driver, restart networking using the following commands:

/etc/init.d/network stop

NFS Server configuration Centos 6 And RHEL 6

Network File System (NFS)

Network File System (NFS) is a network file system protocol originally developed by Sun Micro systems. It allows your users or client compute to access files over a network. Linux and UNIX like operating systems (including MS-Windows) can mount file system over a network and work as they are mounted locally. This is perfect for sharing files or centralized home directories.

NFS version 4 provides the following benefits over NFSv3 or earlier NFS versions:

  1  Performance improvements
  2  Mandates security and ACL
  3  NFS v4 by default works over TCP s
  4  Easy to setup firewall option
  5  And much more.

Required Packages

nfs-utils - The nfs-utils package provides a daemon for the kernel NFS server and related tools, which provides a much higher level of performance than the traditional Linux NFS server used by most users.

Install NFS Server

[root@server Desktop]# yum install nfs*

[root@server Desktop]# mksdir /data

[root@server Desktop]# chmod 777 /data

Share File System

[root@server Desktop]# vim /etc/exports

/data   *(rw,sync)

save :wq!

Start NFS services

[root@server Desktop]#service nfs restart
Sample outputs:

Starting NFS services:                                [  OK  ]
Starting NFS quotas:                                  [  OK  ]
Starting NFS daemon:                                  [  OK  ]
Starting NFS mountd:                                  [  OK  ]

Turn on services

[root@server Desktop]#chkconfig nfs on

[root@server Desktop]# showmount -e 10.90.12.1
Export list for 10.90.12.1:
/data *

To Show Mount
[root@server Desktop]# showmount -e 10.90.12.1
Export list for 10.90.12.1:

To Mount Share File
[root@server1 ~]# mount 10.90.12.1:/data /mnt

[root@server1 ~]# ls /mnt/
abc  bnd  yt
[root@server1 ~]# touch /mnt/abc


[root@server1 ~]# umount /mnt

YUM Server configuration Centos 6 and RHEL 6

Advantages of YUM

Automatic resolution of software dependencies. If a package installation or upgrade request is made and requires the installation or upgrade of additional packages, YUM can list these dependencies and prompt the user to install or upgrade them.
Command-line and graphical versions. The command-line version can be run on a system with a minimal number of software packages. The graphical versions offer ease-of-use and a user-friendly graphical interface to software management.
Multiple software locations at one time. YUM can be configured to look for software packages in more than one location at a time.
Ability to specify particular software versions or architectures. Software locations accessible by YUM can contain multiple versions of the same RPM package and different builds for different architectures such as one for i686 and one for x86_64. yum can easily check the appropriate version and download it.
While it's unlikely that you'll have an Internet connection during the exam, you could have a network connection to a local repository. So you should be ready to use the yum command during the Red Hat exam.

Server side configuration:
Step 1:
Install createrepo.rpm from the DVD for creating repository.

How to Configure Primary DNS Server in redhat 6 Step by Step

Domain Name System

The Domain Name System (DNS) is the crucial glue that keeps computer networks in harmony by converting human-friendly hostnames to the numerical IP addresses computers require to communicate with each other. DNS is one of the largest and most important distributed databases the world depends on by serving billions of DNS requests daily for public IP addresses. Most public DNS servers today are run by larger ISPs and commercial companies but private DNS servers can also be useful for private home networks. This article will explo
