i modified my dhcpd.conf file like this:
--------------------------------------------------
option domain-name "linuxlab";
option routers 192.168.11.254;
option root-path "192.168.11.254:/opt/ltsp/i386";
option option-128 code 128 = string;
option option-129 code 129 = text;
option broadcast-address 192.168.11.255;
option subnet-mask 255.255.255.0;
default-lease-time 604800;
next-server 192.168.11.254;
group LABClients {
next-server 192.168.11.254;
if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
filename "/ltsp/i386/pxelinux.0";
} else {
filename "/ltsp/i386/nbi.img";
}
host studente1 {
hardware ethernet 00:1d:0f:ff:d1:07;
fixed-address 192.168.11.101;
}
[...]
host studente10 {
hardware ethernet 00:d0:09:17:57:5d;
fixed-address 192.168.11.110;
}
}
--------------------------------------------------
but it doesn't works.
so i tried dhcpdump and it gives me this (this is the reply):
---------------------------------------------------------------------------
