One of my friends had trouble configuring Apache2 on Ubuntu. I suggested my friend these steps to fix the problem. Configuring Virtual host in Apache2 is very straight forward. It is easy to find what you need in Ubuntu documentation. The below link clearly explains how to configure Apache2.

https://help.ubuntu.com/7.04/server/C/httpd.html

These are the least steps required to configure virtual host in Apache2. If you run into problems please refer the online Ubuntu documentation or Apache2 documentation.

To install Apache use the command
"sudo apt-get install apache2"

I started using Linux on my servers few years ago. I had a strong notion that Linux was not suited for desktop computers. Later, I realized that Linux is even more friendlier than the (proprietary) operating system I was using before. In my humble opinion, Ubuntu is one of the best Linux distributions available today. Ubuntu has plenty of packaged application software and drivers which are very essential. Out of the box, all these software packages work great. You can start using these instantly after installing Ubuntu.

I am having 64bit AMD system in which I was unable to play flash files in Mozilla firefox. I initially tried with gnash which is an open source version of flash player but i felt gnash still not mature enough to handle flash files as good as Macromedia Flash player so decided to go for Macromedia Flash player. First we need to uninstall if any gnash installed and then install Macromedia Flash player plugin-in for Mozilla Firefox. But the problem is Macromedia 64 bit flash player is not available for Ubuntu 7.04.
