Hi all, I just setup up an LTSP server on ubuntu 8.04 and the edubuntu add on package. I installed everything but when I connect a client it gives me the following: PXE-T01: File not found. PXE-E3B:TFTP Error - File not found The server is 64 bit and the clients are 64 bit capable. I did some digging and I found my /etc/ltsp/dhcpd.conf. This is what it has: # # Default LTSP dhcpd.conf config file. # authoritative; subnet <a href="http://192.168.0.0">192.168.0.0</a> netmask <a href="http://255.255.255.0">255.255.255.0</a> {     range <a href="http://192.168.0.20">192.168.0.20</a> <a href="http://192.168.0.250">192.168.0.250</a>;     option domain-name "<a href="http://example.com">example.com</a>";     option domain-name-servers <a href="http://192.168.0.1">192.168.0.1</a>;     option broadcast-address <a href="http://192.168.0.255">192.168.0.255</a>;     option routers <a href="http://192.168.0.1">192.168.0.1</a>; #    next-server <a href="http://192.168.0.1">192.168.0.1</a>; #    get-lease-hostnames true;     option subnet-mask <a href="http://255.255.255.0">255.255.255.0</a>;     option root-path "/opt/ltsp/i386";     if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {         filename "/ltsp/i386/pxelinux.0";     } else {         filename "/ltsp/i386/nbi.img";     } } I know the error that PXE is giving me is  because I did not run this command <pre>ltsp-build-client --arch i386</pre>and the i386 image file is not created. My question is: Is it possible to have amd64 and i386 image files and select which one the thin client uses to boot? Maybe by modifying the if statement in dhcpd.conf or have options on boot of the thin client? Thanks -- Nicolas Roussi
