There are several things wrong here.

First I should point out RedHat 7.1beta comes with BIND 9 as a package.
Second if you're using BIND 8 named config files and you don't have a top line which
looks like:
$TTL 86400

before your SOA record, then you will see the message about "no ttl".

Thirdly, and this is really the only kernel-related one, it appears that
named is asking for support for TIMESTAMP on the socket and it's failing.
I don't know why that is, as it looks like the TIMESTAMP socket option is supported
in 2.4 (presumably 2.2 as well).
