Add something like this to the global scope. There is some information
in the dhcpd.conf man page in th esection "CLIENT CLASSING".
option ftp-server code 161 = array of ip-address;
option ftp-user code 162 = string;
class "wyse1k" {
match if option dhcp-vendor-identifier = "wyse-1000";
option ftp-server 192.168.1.4;
option ftp-user "anonymous";
}
No changes are needed to the subnet definition, the devices will pick
up the options if they match the class.
