Here we’ve come with a tool which is not for your help but for creating troubles for you.Ya you got it right guys-we are going to create some problems for you which you need to sort out.

A very good morning to all of you. Today we’ll install Webalizer Web Stats Analysis Tool on your Linux machine.Webalizer generates detailed and highly configurable reports which can be viewed on your browser. To have more details about Webalizer and download it you can visit its official site. With RHEL5 it’s already available.So let’s start the installation process.

To install Webalizer all you need to do is to issue yum install webalizer command. But if at this point you’ll try to open http://localhost/webalizer you’ll get an error regarding Page Not Found. So we’ll need to configure it a bit.Following are the steps to configure it properly-

Make a directory /var/www/html/webalizer using mkdir /var/www/html/webalizer command.

Copy contents of /var/www/usage/ directory to /var/www/html/webalizer by using cp /var/www/usage/* /var/www/html/webalizer command.

Now open /etc/webalizer.conf and set outputDir to /var/www/html/webalizer.

That’s all.Now run webalizer command and you can view your Stats page in your browser.

Many of you will be familiar with memtest utility.MemTest is a RAM tester that verifies that your computer can store and retrieve data from memory without any error. A computer may fail in these tests because of old hardware, damaged hardware, or poorly configured hardware and it will be less stable and crash more often. Even worse, corrupted data is written to your hard disk which may create further problems. By running MemTest you can ensure that your computer’s RAM is correctly functioning.

Now let’s see how we can use it on a Linux machine. As you know I use RHEL so here I have demonstrated the installation on a RHEL machine.Memtest package is provided with the RHEL software package and all you need is to issue yum install memtest to install it.Now from the terminal issue memtest-setup command.This will configure your grub.conf file to add memtest in its menu.

Now to see it in action just restart your machine and press e when you get a prompt stating press any key to continue.Here you will see an added entry besides your kernel. Just select it and continue booting and you’ll see memtest screen as shown in the screenshot above.
