Thanks for your reply. I follow your suggestion and I found
that the mathpass file was in the directory
Still it had a "root" mashine ID number in it wheras ordinary
user generates different mashine ID number.
I do have network card attached to my computer but I have not
configured it yet ( I planning to do so).
Maybe this card is a problem?
I have installed mathematica as a root with single mashine license.
