Thanks for the details, David! I really appreciate it.
Am now running the 4.1.1 client (FreeBSD
8) and server (Solaris 10u4). As I understood the DDNS section of the
client man page, have the client configured like this:
[root at freebsdvm8 ~]# cat /usr/local/etc/dhclient.conf
send fqdn.fqdn "freebsdvm8.apevt.local.";
send fqdn.encoded on;
send fqdn.server-update off;
also request fqdn, dhcp6.fqdn;
interface le0 { send ia-na 0; }
id-assoc na 0 { }
[root at freebsdvm8 ~]#
The last two lines were left over from a previous attempt using the KAME client.
The server is the same, except that:
1) have moved the host record out of subnet6 as I haven't a clue what subnet-scoped-host-records do, and
2) have taken the default-duid from:
[root at freebsdvm8 ~]# strings /var/db/dhclient6.leases
default-duid "\000\001\000\001\022\350\2214\000\014)\364\206\204";
[root at freebsdvm8 ~]#
and stuck it into the host definition as the dhcp6.client-id:
host freebsdvm8 {
host-identifier option dhcp6.client-id "\000\001\000\001\022\350\2214\000\014)\364\206\204";
fixed-address6 2bad:0000:0564:0001::22;
}
The good news is that DHCPD seems to be offering up the stateful
fixed-address6 to this host; the bad news is the host doesn't accept it. Am pretty sure the client is now sending the FQDN, but am not confident at all on the rest of the config, as even stateless addresses offered by dhcpd are not accepted. Any thoughts?
Thanks -Brett
