managing a small network - 2 newbie questions
i've been an intermediate-level linux user for some years, and now i'm supposed to set up and manage a small network for our research group.
we have 5 linux boxes with ubuntu 10.04 (actually i'm installing everything we need in one box and will attempt to clone the others with clonezilla). i've 2 questions:
1) i'd like to manage all user accounts from one pc (server? so to say), so that every user can log in any of the 5 machines with the same passwd etc. what is the best/easiest/most stable application/protocol to manage this?
2) is it possible to create a network logical volume, based on the individual HDs and visible to all boxes? something like a RAID0 over ethernet? any suggestion of protocol/application?
