I could also killx on my server when I"m not there...and have top running. That's a good idea. I assume they're running openoffice and firefox. We haven't done any teaching about available software; we just plopped down the edubuntu instead of the winXP. -peter Harry Sweet wrote: <blockquote cite="mid:48562EB3.C484.0066.0@gcsny.org" type="cite"> <pre wrap="">Hey, my nephew graduated from your school last year. Sounds strange. My server occasionally freezes 7.10 and now 8.04, but that has usually just been Gnome on the server. You can try to use putty to log in remotely and restart. If that works. You can also run top or htop to watch the thing die in realtime. Might tell you something. I can see when I run out of memory on my box and what processes are running. What software are the kids running when the thing dies? harry sweet Goshen High School </pre> <blockquote type="cite"> <blockquote type="cite"> <blockquote type="cite"> <pre wrap="">Peter <a class="moz-txt-link-rfc2396E" href="mailto:peter@beetlebolt.com"><peter@beetlebolt.com></a> 6/15/2008 12:59 PM >>> </pre> </blockquote> </blockquote> </blockquote> <pre wrap="">After months of testing, I made our edubuntu thin client system live and it froze ... twice... and I can't figure out why. We're using Edubuntu 7.10. We're running a dell poweredge, 2.8ghz p4 (I'm sure it's a 2.something p4), 1gb ram, raid 1 array of 200GB+ with 5 clients (1ghz p3, 256MB ram). All 10/100 network equipment. When any of the clients boot and log in, it's fast...so nice and fast. But after the system has been running a few hours and students begin to use it (and I'm not there). It freezes hard. I *think* it freezes hard b/c I haven't tested pinging it when it's down. But it doens't reply to anything including ctrl-alt-bkspace, or ctrl-alt-f1. And I know the /var/log/messages file stops creating --MARK-- entries during this time. When I find it frozen, there is video, but no response to mouse or keyboard. In our tests, we only experimented with 1 client. Could 5 clients create too much demand on our server? I recently installed the ssl update and rebuilt the images...could I have done something wrong there? And one more detail: we're posting our username-password info per computer...it's conceivable that one user might be getting signed in more than once. Would that do it? Or how about using Adobe Flash 9? thx so much, -peter Bard High School Early College NY, NY </pre> </blockquote> </body> </html>
