I did the tcpdump as suggested, you can find it attached ... Now I'm thinking to replace the DHCP server, but I need something on the server itself, or on a device (the router, maybe) since I cannot ask the teacher to: 1- start a service machine (acting as a DHCP server) 2 - wait until it's up&running 3 - start the server 4 - start the TCs Way too tricky for people used to switch on a general button and have all the PCs running (OK, WindowsME, but) What about a router ? I also need to assign fixed IPs to specific MAC adddresses to be able to use iTalc ... :-(  I'm very sad about this .... -------------------------------------- Message: 5 Date: Wed, 17 Dec 2008 22:17:36 +0000 From: Gavin McCullagh <<a ymailto="mailto:gmccullagh@gmail.com" href="mailto:gmccullagh@gmail.com">gmccullagh@gmail.com</a>> Subject: Re: DHCP server sometimes not found To: <a ymailto="mailto:edubuntu-users@lists.ubuntu.com" href="mailto:edubuntu-users@lists.ubuntu.com">edubuntu-users@lists.ubuntu.com</a> Message-ID: <<a ymailto="mailto:20081217221736.GD12257@gmail.com" href="mailto:20081217221736.GD12257@gmail.com">20081217221736.GD12257@gmail.com</a>> Content-Type: text/plain; charset=us-ascii Hi, On Wed, 17 Dec 2008, Sergio Dicandia wrote: > Has anybody tried this with Intrepid ? > Maybe they fixed it in the new release ... Several of the LTSP developers read this list so if they know of this problem and a fix to this, you may be sure they'll say. In the meantime, we need to document this better for them. Can you please do the tcpdump on the server so we can make sure of what's going on (give us the tcpdump trace along with what roughly moments you booted what machines/mac addresses).  It sounds like this _might_ be a nasty bug which several people have seen and if so, we need to know exactly what happens.  If there's a serious issue we need to reproduce it and pin it down so the developers can fix it.
