Thank You KMDave!
You didn't convinced joshiley to learn linux from scratch and stay away from BT4, but you did convinced me. I saw once the LFS website but I did not download the livecd and I didn't care about it. Now, 15min until the download of the iso ends. I'm newbie but I tried to learn linux basics with BT. I did take little steps in WEP/WPA cracking, Wireshark/Ettercap (sniffing) packets analysis and other tools that "calls" the basics knowledge from the brain. My VMware BT4, pentoo,De-Ice machines will remain on my HDD but certain it will be the VMware LFS who's running frequently from now on, until I'm more comfortable and confident with my linux knowledge.

Thank You for pointing me in the right direction!
