That depends. If he already has 10 powerfull workstations with local disks, than using them as thin-clients is a waste of resources and your idea may be better. However, if you have 10 old PC's (e.g: I use old diskless Celleron-300Mz) than there isn't much point in trying to use their CPU+ram other than driving the display. Note that if the 10 users are running "average" mix of CPU+I/O jobs (interactive applications) than hosting them on a single powerfull server would give better performance per dollar than buying each his own "thick" client (this is obviously due to the fact that CPU and I/O resources are multiplexed). Where does the theory in the previous paragraph fail? When the large computer isn't anymore a commodity computer (something that you cannot buy at the local computer store, so its price is jumping high). But a current comodity high end PC (e.g: a P4-3Ghz, 2GB ram) can easily host 4-5 desktop users with reasonable performance (ok, add another 1Gb if they all use openoffice :-) > Do you use nbd?

I didn't even bother looking at performance since my goal wasn't a disk (why would I want a disk on a thin client? better have it on the server). I wanted to use it so the local floppy + cdrom would be remoted to the server... > > The missing pieces (IMO): > > - Handling removable media (haven't found a way to handle > > this via nbd). > > And did you search for one? Not that I critisize - on the contrary. No I didn't (no time), any pointers would be appreciated, thanks. -- Oron Peled Voice/Fax: +972-4-8228492 [EMAIL PROTECTED] http://www.actcom.co.il/~oron ICQ UIN: 16527398 "Your fair use of this book is restricted" "You may only read this book once" ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
