please help me get some tutorials


Guys let me say it frankly , I know nothing about linux, I know nothing about servers. and Now that I have VPS I am very much scared touching it installing things and so on.

I know some sites but still I do not understand most of the terms.
Video tutorials are best for me but most video tutorials I find are
thos basics like how to use your cpanel.

I need to learn Any Idea where can I get video tutorials?
I am very much tired , I do not need to become professional but at least it seems I have to learn to secure my server installing some firewalls bla bla

Please help me with this.
