Is Linux more secure then Windows ??
There was a hammered attack in corporate network with a slew of viruses and worms, and nearly all of them focused on the vulnerabilities in Mirosoft’s softwres. People started moving from windows to Linux, but the question is, Is Linux really SECURE then Windows????
Answer is, yes for now….
Well each operating system has its security strengths and weaknesses. Windows flaws have been cropping up faster than some people can track, forget patch. But Linux has its own troubles with vulnerabilities. They simply don’t get as much media attention. And that’s because Linux isn’t as ubiquitous as Microsoft’s Windows. Windows flaws get more attention because nearly everyone — from Fortune 100 security managers to their mothers and neighbors — needs to know about them.

Advantages of choosing Linux web hosting
Linux web hosting refers to web hosting services that are based on a server that is running the Linux operating system. It is probably the most widely used type of web hosting, especially for individuals and small to medium sized businesses, simply because Linux web hosting is cheaper than other options like Windows based hosting. The reason for this is that Linux is an open source software product and as such does not incur the high licensing fees that other operating systems do; you can freely download and use it at no cost. On the other hand, a web hosting service that offers Windows based hosting has to pay for the software and maintenance fees.
Some of the advantages of Linux web hosting are: cheaper than Windows, support for PHP scripts and MySQL databases and some hosts may offer telnet accounts at no or little additional cost. In many circles Linux is believed to be more secure than Windows, and for that reason it is also the more popular choice for web designers and programmers. Linux web hosting also offers users many configuration and customization options.
The Linux operating system is also very stable, so you can expect high uptime from a Linux web hosting service. Linux supports most scripting languages and types of web files, and you can use files with all the following extensions: .html, .htm, .pl, .php, .shtml, .asp, .xml and others. The biggest disadvantage of a Linux based web hosting solution is that it is not compatible with Microsoft technologies, like ASP scripts.
Is command line really so bad??
All the Linux bashers use this as an excuse/reason why Linux is not suitable as a desktop operating system. You should never have to use the command line they say. You should have to be able to configure your whole computer just by clicking the mouse. People find the command line confusing and difficult and all.
But, I personally don’t think the command line is really bad at all. Every operating system has a shell and the ability to run commands directly without using a mouse. Most technical support sites give instructions for solving problems with command line commands. And even microsoft does provide instructions to solve problem via command line…
Command line is the most powerful way to control a computer. It has been in existence since the beginning of computing time and it will not go away soon. It is even making a comeback in the windows world with their windows 2008 server and the vista power shell.
So what is so bad about it? It is the single most effective way to help someone. If they have a problem you just give them a few commands which can be copy and pasted and poof! The problem goes away. For diagnosing a problem the command line is great too. Just running a program from a command line can give you more information than a cryptic general protection error. Then that information can be copied and pasted onto forums so others can help.

Important Post Installation Step
Using OpenVZ
OS Templates – Linux Distribution Install Media
The vzctl command is used to create and configure OpenVZ containers. Before you can create a container, you need install media for the Linux distribution you want to install. OpenVZ can NOT use CD / DVD install media (NOR .iso disk image files). OpenVZ requires what it calls an OS Template to create a container for a given Linux distribution. You can download a number of pre-created OS Templates from the OpenVZ website. This is the recommended route for new OpenVZ users. Once you are more familiar with OpenVZ you may want to create your own OS Templates from scratch using a variety of recipes available on the OpenVZ wiki. You can find pre-created OS Templates provided by the OpenVZ Project here:
http://download.openvz.org/template/precreated/
You can also find community contributed OS Templates here:
Installing OpenVZ on CentOS 5.2
The OpenVZ Project website (www.openvz.org) has a lot of quality documentation including a Users Guide PDF, a Quick Installation Guide, and a vast wiki of howto and troubleshooting articles. This article will briefly cover the installation process. You will need to be the root user for all of the following tasks.
Adding the OpenVZ yum repository
Installing OpenVZ on a CentOS 4 or CentOS 5 host is very easy because the OpenVZ Project provides an openvz.repo for use with yum. Simply download the openvz.repo file and place it in the /etc/yum.repos.d/ directory. Examine the openvz.repo file as it contains a number of repository definitions with two being enabled by default: 1) RHEL5-based kernel and 2) the OpenVZ utilities. Edit it to meet your needs. More »
OpenVZ
What is OpenVZ?
OpenVZ is operating system-level virtualization based on a modified Linux kernel that allows a physical server to run multiple isolated instances known as containers, virtual private servers (VPS), or virtual environments (VE). The preferred term these days is container. Containers are sometimes compared to chroot or jail type environments but containers are really much better in terms of isolation, security, functionality, and resource management.
OpenVZ consists of a custom Linux kernel (available from the OpenVZ Project) and some user-level tools. OpenVZ is very portable, does not rely on VT support in the CPU, and as a result it is available for a number of CPU families including x86, x86-64, IA-64, PowerPC and SPARC.
OS-level virtualization is quite different from machine / hardware virtualization products such as VMware Server, Parallels Workstation, VirtualBox, QEMU, KVM, and Xen in that with OpenVZ you can only do Linux on Linux virtualization.
