Hi me and my friend are starting to learn about security so i went out and got 5 computers and installed linux or windows XP on each of them. They are all on my LAN so i have constant access but im not sure how to set it up so my friend can use them like a shell account i guess. I have a Linksys DSL Router going into a Cisco 1900 catalyst hub. (i have a cisco router too but it has the T1 card in it not the DSL one) Pleez help me out thnx. and let me know if i need to explain myself better b/c im obviously not the most articulate
