I'm new in linux and I don't know how to connect my red hat 9 linux with my Win Xp Pro in a peer to peer configuration. And how to connect linux with linux too because one computer have a partitioned drive with Win XP Pro and Red Hat 9. And the other just got linux ( red hat 9 ). I will appreciated your help. ( If know Spanish more better ).

I'm guessing you are looking to share files between computers.
The easiest way is to use samba between windows and linux. I store all my files on my linux boxes to make it easy to use from all my computers.
The easiest way to share linux to linux is to use nfs. You can search for spanish translations to guides on these topics on www.tldp.org searching for samba, smbfs, cifs, and nfs.

If you can afford the time, band width, and 4 cd's to burn using a burner, I'd recommend using Fedora Core 3 or 4 the lastest in the open source red hat line. (Friends are sometimes helpful.)

If you have any problems along the way post again on this thread and i'll watch for it so that I can help you with any incorrect examples or problems.
Your english is very good.
