Re: [Dnsmasq-discuss] Vendor and User class compounds

Hi,

I want to put some options for some hosts with the network-ids match system.

These hosts are defined by such a test :

    (vendor-class = "Vendor_1" and
    (user-class = "device_1" or
     user-class = "device_2" or
     user-class = "...")
    ) or (
    vendor-class = "Vendor_2" and
    (user-class = "device_A" or
     user-class = "...")
    ) or (
    vendor-class = "Vendor_3" and
    (user-class = "device_AA" or
     user-class = "..."))
    ...

Have you an example of a dnsmasq.conf file for this case ?

You need to do this in two stages: first set network-ids based on the
vendor-class and user-class ids:

dhcp-vendorclass = vendor1,"Vendor_1"  # sets tag vendor1
dhcp-vendorclass = vendor2,"Vendor_2"  # sets tag vendor2
# etc

dhcp-userclass = user1,"device_1" # sets tag user1
#etc

then you take advantage of the fact that dhcp-option lines can have more
than one tag, with an implied AND function. To get the OR function you
need to repeat the dhcp-option

dhcp-option=vendor1,user1,56,....... # send option 56 to hosts which are
                                    # vendor1 and user1

dhcp-option=vendor2,user2,56,....... # OR to hosts which are vendor2 and
                                    # user2
etc.

Thanks Simon,

We need another setup for these particular hosts.
We want to use the same range, with --dhcp-range, for all these hosts.
Is there a possible syntax AND/OR with this option ?
