Hi Jim, Interesting, I think, that the newer clients take 1/4 of the time of the older. This seems to imply that the cause isn't just on the server?
I've not specifically added clients to /etc/hosts. What does this do? "LDM_DIRECTX=*True" *what does this do? I had heard of fl_teachertool but am just checking into it. Seems like it has more features than iTALC, an alternative project. I looked for a comparison of the two, didn't find much though looks like it might not be kept up? Author says might want to go for iTALC for this reason... http://www.linux.com/archive/feature/151686 What do you think? Ever tried iTALC? Yes, we'll get through this :) David On Sun, Nov 15, 2009 at 10:12 AM, Jim Christiansen < [email protected]> wrote: > Hello David, > > I haven't topped the server yet at client log on yet.
