I am currently studying for the Linux + certification. I work with Linux alot becuase of my web site work. This is typically all command shell through SSH, Webmin, or WHM. I am forcing myself to use Linux on a daily basis as my workstation so I will learn it even more. The flavor of Linux I am using is CentOS. One of the tools I use is Skype. Skype does not have a RPM package for CentOS. This application has to be installed manually. I had to figure out how to get this installed. Here are the steps I took to install this and configure it.
INSTALL:
Skype only comes in 32 bit so if you have a 64 bit machine you need to run the following to install 32 bit libraries. This is required to run the 32 bit Skype application.
yum install glib2.i386 qt4.i386 zlib.i386 alsa-lib.i386 libX11.i386 \ libXv.i386 libXScrnSaver.i386
