-Ok, here is a diff for etherboot 4.6.0 that adds identifiers.
-
-To test this you need to use a class in the dhcpd.conf file and
-also send back a string in option 208.
-
-These identifiers prevent a client from booting from other DHCP
-servers when you have more than 1 in your network.
-
-In will also prevent any client, except the valid ones, to use this
-DHCP server.
-
-Here is a subset of my dhcpd.conf :
-
-option iNdiskless-state code 208 = text;
-
-class "iNdiskless-boot" {
- match if substring(option iNdiskless-state,0,4) = "BOOT";
-}
-class "iNdiskless-setup" {
- match if substring(option iNdiskless-state,0,5) = "SETUP";
-}
-
-subnet 10.4.1.0 netmask 255.255.255.0 {
-pool {
- allow members of "iNdiskless-boot";
- deny unknown clients;
- range 10.4.1.2 10.4.1.200;
- next-server 10.4.1.1;
-
-# Identify ourselves to the etherboot/DHCP client
- option iNdiskless-state "BOOT";
-
- host labo01 {
- hardware ethernet 00:80:c8:ec:04:1b;
- }
- host labo02 {
- hardware ethernet 00:4f:4c:04:45:d6;
- }
- host labo03 {
- hardware ethernet 00:50:ba:c8:db:d6;
- }
-}
-pool {
- allow members of "iNdiskless-setup";
- range 10.4.1.201 10.4.1.254;
- option iNdiskless-state "SETUP";
-
-# send another kernel to setup the diskless workstation
