problem updating dynamic dns from isc dhcpd

Simon,

Man page makes that look like an update/access issue, I'm not being rejected for access, but seemingly because the domain name isn't being recognized.

A ddns-domainname is domainname issue, I think.

Thanks,
Brian

Do you have zone statements in your dhcpd.conf ?
If not using secure updates, you can just rely on having the zones correctly set up (correct SOA record) and dhcpd will find the master server from the SOA record. But since you are using signed updates, you must specify zones in dhcpd.conf - the syntax is *almost*, but not quite, identical to that in named.conf.
