Using "vendor-encapsulated-options" in dhcpd

[Victor Soriano]

Hello all,

New to the list, and I searched the archive for the following
question(s) and didn't find anything, so please don't flame me too
hard :)

I'm trying to configure dhcpd V3.0pl1 to transmit DHCP option code
125, defined as a Vendor-Identifying, Vendor-Specific option as per
RFC 3925, along with a proprietary buffer. For now, I need this buffer
to ALWAYS be sent out in the DHCP server's messages, regardless of the
client.

First, does this option correspond to using the
"vendor-encapsulated-options" option in dhcpd.conf? If not, how can I
have the DHCP server send a buffer with this option?

If using "vendor-encapsulated-options" is correct, how should it be
used in the file? I have tried the following dhcpd.conf as a test and
never see the server include this option in its messages.

        get-lease-hostnames true;
        authoritative;

        max-lease-time 86400;

        }

        pool {
                range 192.168.0.100 192.168.0.199;
        }
}

I also tried defining an option space, using a buffer more like what I
really need, with no luck:

----------
ddns-update-style ad-hoc;

option space TEST;
option TEST.oid code 1 = text;
option TEST.sn code 2 = text;
option TEST.class code 3 = text;

option TEST.oid "112233";
option TEST.sn "11:22:33:44:55:66";
option TEST.class "test";

subnet 192.168.0.0 netmask 255.255.255.0 {
        get-lease-hostnames true;
        authoritative;
        default-lease-time 86400;
        max-lease-time 86400;

        option domain-name "hans-eth0";
        option domain-name-servers 192.168.0.1;
        option routers 192.168.0.1;
        option ntp-servers 192.168.0.1;
        vendor-option-space TR111;

        host hans.hans-eth0 {
                fixed-address 192.168.0.1;
                hardware ethernet 00:00:d1:ee:41:70;
        }

        host franz.hans-eth0 {
                fixed-address 192.168.0.2;
                hardware ethernet 00:07:e9:09:be:fe;
        }

        host greta.hans-eth0 {
                fixed-address 192.168.0.200;
                hardware ethernet 04:4b:80:80:80:03;
        }

        host bertha.hans-eth0 {
                fixed-address 192.168.0.201;
                hardware ethernet 04:4b:80:80:80:04;
        }

        pool {
                range 192.168.0.100 192.168.0.199;
        }
}

Any help on how to get this up and running would be greatly appreciated.
