thanx for the info's Guys . It is true that I don't need to learn Linux to start my hosting business . I can hire professional help which I am doing . But , charges are always a factor . Also ... it is MY business so ... I prefer to know what is being done so that I never loose out control at any point of time . My customers are very valuiable to me .
any other book recomedations would also be nice . I will d some purchasing after I get some sort of consensus or at least more than one opinion .
I would suggest getting some very basic books such as dummy's/ or idiot's book on the subject (not implying you are one ) from my experience I found the Maran books is of better teaching aids as most of their books are "Teach Yourself.. visually-"The fast and Easy Way To Learn" as the say, "A Picture is word a thousand words" I guess it could be very true.

Once you have surpass the steep learning curve on Linux, then your are ready to look through on more advance books on the subject. One good source of searching is your local library.
