Hmm... well if I understand you correctly, you want to set up a home network.
You can use Samba, or you can use NFS. Samba is the same protocol that windows uses with it's networking, so if you'll ever be working with a windows user or if you'll ever be working with windows on one of your computers, Samba is the way to go. NFS on the other hand, is Unix based. I don't know much about it, so maybe someone else can enlighten us both!
these two tutorials helped me out a lot. They aren't for Mandriva, but you can get the point from them.

So I think that's what you wanted, but if you have any more questions, let me know.
