We took dhcp off the ltsp server and put it on a separate box (a low power P4) and suddenly were able to boot 30 clients at the same time (with ltsp5). It seems that ltsp5 hammers the dhcp server (at least from Ubuntu, that's all we've tested so far), I think if you watch the logs you find the clients querying the dhcp server over and over again. We figured that as the box got busy serving up the tftp kernels the dhcp would start to fail/timeout. For this and other reasons (Active Directory authentication hammering the server too, general slowness) we went back to ltsp4 (on Debian) and things are working much better there in general, it's much faster!

Everything seemed fine on the first clients I tested, but I just found I can start no more than 4 or 5 at the same time. The other ones just wait for a DHCP to give them a valid IP address, and there's no way to obtain it. I checked cabling and switch, but it's just a matter of who come first: the first 4 (or 5) clients just get their IP, the other ones don't. Consider that in my /etc/ltsp/dhcpd.conf I put the correct MAC addresses to assign fixed IPs, and they work fine for the first clients starting. Looks like somebody had the same problem, while everything worked fine in 7.10 with LTSP 4.2: http://209.85.129.132/search?q=cache:Jj3ycleLzasJ:sudan.ubuntuforums.com /showthread.php%3Ft%3D830748+edubuntu+dhcp+problem&hl=it&ct=clnk&cd=8&gl =it&client=firefox-a Any suggestion ? It's the last obstacle to get our only computer room working ... TIA, Sergio
