Built two new LTSP servers,strictly for a test bench setup from a couple of decent desktop machines. 1. Some of my findings is that the boot time for any client is very slow. From 150-180 seconds from the time the client gets the dhcp request to a login screen. That doesn't sound like a long amount of time,unless you are sitting watching it! It is almost 120 seconds for loading the initrd image. I tried this on both servers with even a direct server to client ethernet wire / nics,,,,no switch even in the picture and also with a switch GIG-E just to verify. Didn't make any difference with a switch or direct ethernet connected,for completeness. 2. I never even see the plymouth booting screen or the progress bar along the bottom,,not that that is a big thing,but somewhat tells me possibly the initrd image is not building right at client build. 3. 4 of the test netbooks, various makes,models we have that boots fine with the older SL6.1 build of k12Linux when booting with the new servers starts to go through the boot process to a certain point then the monitor just goes black. I can't see anything in the server message logs of anything wonky of course. 4. I haven't ever tried going to the nbd boot setup,just adding this for completeness. I have been trying to make some headways on this for the last couple days,when I have some time available,but haven't tried to see if even usb sticks are working. Just curious if anyone on list ha done a recent server/client build of ltsp?

I am not sure at all why the first two installs seemed so slow in regards to client booting times? Wanted to mention that even with the latest EL6 kernel there is a problem with some of the Broadcom nics "stack trace",,,stopping while booting up. For example the HP T5730's would boot fine but the HP T5740 would stop at a "stack trace". Doing some research it seems the later has a slightly different setup in the firmware. Seen some suggestions of installing the kmod-tg3 latest 3.1.33rpm from the elrepo repository. Sure enough this did fix the stack trace" problem at boot,and seems to be working fine. Only caveat is both the HP T5730 and the HP T5740 when doing a reboot/shutdown hangs at "shutting down ethx" and never does go past this. The HP T5730 that would boot without the added on tg3 driver would also hang with the native tg3 driver that is in the latest EL6 kernel.

Your Shuttle box got me looking which turned up some even cheaper options (potentially anyway, depending on your case/PS requirements: http://www.newegg.com/Product/Product.aspx?Item=N82E16813157498 That one is mini-ITX and has 2 video outputs (HDMI/VGA). http://www.newegg.com/Product/Product.aspx?Item=N82E16813157514 This one has triple video but is uATX. While both of those are a bit slower than the 1037u they also take less power. Nice to see a good variety of Intel fanless motherboards with linux support available for cheap ($60) again. Jeff
