I'm actually using the domain nine.homelinux.com, since homelinux.com is a dyndns.org owned domain. I chowned my db.nine.homelinux.com file to named:named and chmod to 744, but I am still receiving the timeout errors. My dns and dhcp server is my router at 192.168.0.1, so it is the default route and the default dns host. On my fc4 box, marge, I can get the name "marge.nine.homelinux.com" from the hostname command. Below is my /etc/resolv.conf created by the dhcp client.
; generated by /sbin/dhclient-script
search nine.homelinux.com
nameserver 192.168.0.1
Here is my db.nine.homelinux.com file. I keep getting a warning about unexpected end of input near line 6 (the closing paren)
$ttl 38400

And here is my named.conf. It seems everythink is correct, do you see anything I am missing?

Thanks for all the help,

This seems to depend on the client as much as the server. I couldn't
get a Red Hat 9 client to send its desired hostname through to a Red Hat
9 DHCP server, though other client OSs certainly worked fine.

That domain name ( homelinux.com) exists, is it yours? (I see records
for it through dyndns.org.) If not, you're going to have (and possibly
cause) problems.

You're telling those clients to use themselves as their own DNS server
(with the 127.0.0.1 name server addresses, though I see it's commented
out). If they don't also run their own DNS server, and it isn't updated
from your DHCP server, they won't be able to resolve names. The
name-server address would normally be supplied as the address for the
name server that the DHCP server is updating.
My DHCP configuration has the name of the DNS zone it has to update
configured into it. Here's most of mine (minus other subnets):

Could be permissions. I went through lots of fun before I got my DHCP
server working with my DNS server. I had to ensure that the right
ownership rights were applied to the directory where the DNS records
lived ("named" username and group name, rwx for named user, not-rwx to
everything else). And I had to ensure that both the DHCP and DNS
servers were using the same RNDC key. And allow updates with the DNS
server.
