[Dnsmasq-discuss] dhcpd3 to dnsmasq : grouping using the network-id

[Simone]

Hi,

 I'm trying to translate this piece of dhcpd3-server's  configuration
for dnsmasq but I'm quite confuse about the syntax to use for grouping
with ``network-id``.

this is the first part of my configuration ::

    subnet 192.168.11.0 netmask 255.255.255.0 {
        range 192.168.11.200 192.168.11.250;
        option domain-name-servers 192.168.11.254;
        option broadcast-address 192.168.11.255;
        option routers 192.168.11.253;
        next-server 192.168.11.253;
        get-lease-hostnames true;
        option subnet-mask 255.255.255.0;
        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 translated it to :

    dhcp-range=192.168.11.200,192.168.11.250,255.255.255.0,8h
    dhcp-option=6,192.168.11.254  # dns
    dhcp-option=3,192.168.11.253  # gw
    dhcp-option=44,192.168.11.253 # wins
    next-server 192.168.11.253;
    dhcp-option=17,"/opt/ltsp/i386"

    # PXE / Etherboot tagging
    dhcp-vendorclass=pxe,PXEClient
    dhcp-vendorclass=eth,Etherboot

    # assigning (eventually) different servers selecting by tag
    dhcp-boot=net:pxe,/ltsp/i386/pxelinux.0,ltsp-server,192.168.11.253
    dhcp-boot=net:eth,/ltsp/i386/pxelinux.0,ltsp-server, 192.168.11.253
    # other
    dhcp-boot=/ltsp/i386/nbi.img,ltsp-server,192.168.11.253

    dhcp-boot=net:pxe,/ltsp/i386/pxelinux.0,ltsp-server,192.168.11.253
    dhcp-boot=net:eth,/ltsp/i386/pxelinux.0,ltsp-server, 192.168.11.253
    # other
    dhcp-boot=/ltsp/i386/nbi.img,ltsp-server,192.168.11.253

Here starts the problematic part of the dhcpd3-server config, I have
multiple occurrances of selection per-mac :

    host ltsp001 {
      hardware ethernet 00:0c:30:20:b3:13;
      fixed-address 192.168.11.101;
      next-server 192.168.11.253;      # next-server #1
    }

    host ltsp002 {
      hardware ethernet 00:0c:10:11:d1:23;
      fixed-address 192.168.11.102;
      next-server 192.168.11.253;      # next-server #1
    }

    host ltsp003 {
      hardware ethernet 00:0c:10:50:c3:12;
      fixed-address 192.168.11.103;
      next-server 192.168.11.252;      # next-server #2
    }

    host ltsp003 {
      hardware ethernet 00:0c:40:30:b4:15;
      fixed-address 192.168.11.104;
      next-server 192.168.11.252;      # next-server #2
    }


I reserved ip for the hosts defined above :

    # Setting static ip addresses
    dhcp-host=00:0c:30:20:b3:13,192.168.11.101,ltsp001
    dhcp-host=00:0c:10:11:d1:23,192.168.11.102,ltsp002
    dhcp-host=00:0c:10:50:c3:12,192.168.11.103,ltsp003
    dhcp-host=00:0c:40:30:b4:15,192.168.11.104,ltsp004

But I don't know how can I assign multiple mac addresses to a single
network-id ...
I read in the man page that I can use this syntax( valid for a single mac):

  dhcp-mac=<tag>, mac

So I tried to group as follows :

    # Grouping per mac-address, creating 2 different "network-id"
    # network-id: ltspgroup1
    dhcp-mac=ltspgroup1,00:0c:30:20:b3:13
    dhcp-mac=ltspgroup1,00:0c:10:11:d1:23
    # network-id: ltspgroup2
    dhcp-mac=ltspgroup2,00:0c:10:50:c3:12
    dhcp-mac=ltspgroup2,00:0c:40:30:b4:15

And to set different next-server and tftp server by network-id:

    # Setting different "next-server" filtering by "network-id" tags
    dhcp-boot=net:ltspgroup1,/ltsp/i386/pxelinux.0,ltsp-server,192.168.11.253
    dhcp-boot=net:ltspgroup2,/ltsp/i386/pxelinux.0,ltsp-server,192.168.11.252

    # Setting ip of the tftp srever
    dhcp-option=net:ltspgroup1,option:193,192.168.11.253
    dhcp-option=net:ltspgroup2,option:193,192.168.11.252

But I really don't know if I am right. What is the correct syntax?

Thank you in advance,
 Simone
