DDNS, ISC-DHCPD, and Bind... not working because of strange error messages

[Da Rock]

We can top post here?

Thank you! Finally a response... :)
In order of questioning:
No- the pool.ntp.org is what truely confuses me.
Yes- dig ran fine, got an authoritative answer.
Yes- I can get everything. I have an IP address and I can also resolve
all entries in my zone files on bind. I just can't update entries it
seems.

I can understand your point. I'm trying to do the same. Based on these
answers does this mean it dhcpd or bind? I suspect its dhcpd myself.

dhcpd.conf:
server-identifier $serverip
authoritative;
ddns-update-style interim;
ddns-ttl 14400;

key $domain.key {
        algorithm hmac-md5;
        secret "$secret";
};

zone $domain {
        primary $serverip;
        key $domain.key;
};

zone $rev-domain {
        primary $serverip;
};

subnet $private-net netmask 255.255.255.0 {
        range $private-net-range $private-net-range;
        option subnet-mask 255.255.255.0;
        option broadcast-address $private-net-bcast;
        option domain-name "$domain";
        one-lease-per-client on;
        default-lease-time 14400;
        max-lease-time 14401;
        option ip-forwarding off;
        option time-offset -18000;
        option routers $gateway;
 	option domain-name-servers $serverip;
};

I have a question too. I set this up based on very basic info found
through a google search. Should the hostname be set by the client and
updated in the dns by dhcpd? Or should (can I) setup the hostname from
the dns by dhcpd on the client? What is the correct way to do this?

Cheers
