How to create a Local Yast Online Update(YOU) Server?

I use the openSUSE 11.0, and I want to create a Local Yast Online Update(YOU) server. But I don’t get anything about “yast online update server” in the install software list. I remember there is a YOU server in SLES 9, does openSUSE 11.0 have YOU server too? or there is a new software which has taken the place of YOU server in openSUSE 11.0.

I have searched the Forums with the keywords “Yast Online Update Server”, but I don’t get the right answer to the question. May someone help me? Thank you.
