You'll need to allow DNS updates from your local network (not the
world). You do this by allowing updates in named.conf only from
"trusted" subnets. On my server this looks like:
...
zone "local.davenjudy.org" IN {
type master;
file "local.davenjudy.org";
allow-query {
trusted;
};
allow-update {
trusted;
};
};
...
I also remember having to "play with" the permissions and ownership for
the forward and reverse zone files for my local network in order for
this to work. If you need a full example of named.conf, let me know by
private e-mail.
Cheers,
Dave
