[GRLUG] LTSP

[Bill Creswell]

Wow - Thanks!
Does that mean that LTSP does not work with VNC/RDP type thin clients?  I
may have misunderstood the point of ltsp. Is it just and X server?

I did  edit the dhcp for my router, which I presume would also be my
name-server?

I appreciate your help! This might be a good topic sometime too, as more
schools, and homes may be interested in this, especially if there is a linux
program for monitoring usage (Dan's Guardian?).
