I was looking at DRBL to boot teacher machines from, so thanks for the link to the
tutorial. However I would need like this to boot in conjunction with the LTSP server.
I also ran into problems in the past where I could not boot from a Netboot server while
the LTSP server was running. So I am now working on butchering up a dhcpd.conf file
that has a few different subnets. I am hoping when finished all machines for which I do
not know the mac address will get subnet A. Then all ltsp machines will get a
"fixed-address" from subnet B where there will be information to boot the LTSP server
and what root path. I may put another subnet where I can boot kiosks from a different
tree as well. Then I plan on having subnet C loaded with the mac addresses of the new
teacher machines that need to boot DRBL and place the pertinent information under there.
Then I would like to add a subnet D where all Macintosh machines would be assigned and
the next-server info to boot from the NetBoot server.
If this all goes well I will post my results back to the list. I am sure there will be
some major hair pulling in the meantime, but I am sure others could take advantage of
such a setup.
Here is the start of what I have if anyone is interested:
authoritative;
shared-network CotterLAN {
# Unknown Clients assigned addresses here
subnet 10.6.253.0 netmask 255.255.255.0 {
range 10.6.253.1 10.6.254.253;
option domain-name "winonacotter.org";
option domain-name-server 10.6.1.50;
option routers 10.6.0.1;
option subnet-mask 255.255.0.0;
pool {
range 10.6.253.1 10.6.254.253;
deny known clients;
}
}
# Thin Clients assigned specific IP addresses here
subnet 10.6.252.0 netmask 255.255.255.0 {
option domain-name "winonacotter.org";
option domain-name-servers 10.6.1.50;
option broadcast-address 10.6.255.255;
option routers 10.6.0.1;
option subnet-mask 255.255.0.0;
if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
filename "/ltsp/i386/pxelinux.0";
}
else{
filename "/ltsp/i386/nbi.img";
}
option root-path "/opt/ltsp/i386";
host CHS_Main_1 {
hardware ethernet xx:xx:xx:xx:xx;
fixed-address 10.6.252.1;
}
}
}
