TeacherTool is blowing away the folks in Atlanta! Watching the look as we launched 23 simultaneous copies of OpenOffice with one button click was priceless! The speedup with the IP address only (instead of the hostname) I am willing to sacrifice in favor of the hostname list and a way to filter the list. We are going to have 150-180 thin clients per server (Big Servers!) and the fun of a teacher accidentally logging out a student in another room is not something I want to play with :)</blockquote><div> Hmm. This is an issue when you have big servers. Without doing big additions to my code :) I have a couple of ideas. 1) Not sure if each student has their own username but if they are just using generic logins like comp1, comp2, comp3, etc then you can differentiate with usernames like Acomp1, Bcomp1, Ccomp1, etc where A,B,C stand for different rooms. Fl_TT will sort alphabetically so all students in room A will be in one solid block in the list. 2)I just thought of this but it's kind of tricky since dhcp gives out ip's dynamically. If you can manage to tie an ip address to a specific mac address (client machine) you could potentially make each machine according to their mac address (and therefore location or classroom) start a tiny little program at login that does nothing and takes up almost no memory. The important aspect would be the name of the program. Call it "classA" for all computers in room A. I think you get the idea. So you could therebye use the FIND button in Fl_TT to select only those users who are in room A by typing "classA" and hitting FIND. You could then broadcast, logout, whatever and only affect the kids in your room. </div> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I have tweaked the source files and have the hostname back on. If you have any suggestions on a best way to implement a filter ("show only hostnames that begin with foo") I'll look at a patch.</blockquote><div> I'm not sure why ip is less useful than hostnames since by default an ip of say <a href="http://192.168.0.252">192.168.0.252</a> translates to ws252.ltsp. Since Fl_TT can't access another K12LTSP server the .ltsp part of the hostname should always be the same. </div> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Also needed is a way to refresh the machine list without having to restart the tool.</blockquote><div> Just click on the Users button whenever you want a refreshed list. No need to restart. </div> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> -- James P.
