[MaraDNS list] Configuring MaraDNS and Deadwood to work together

[Harlan H. Bloom]

I must have missed in the documentation that I needed to have addresses in both the bind_address and the recursive_acl, making sure the addresses in the recursive_acl had a "/16" after them.  Things are working much better now and I can put the new DNS server into production.

Thank You for your time and attention.

Look over the default dwood3rc file included with your copy of
Deadwood, and try and figure out what each of the parameters does.  In
particular, your issue is that Deadwood works fine with 127.0.0.x IPs
but doesn't work with other IPs.

Note to self: One of these days, add code to raz users when they try
and have a bind_address that isn't in the recursive_acl.  Better yet,
refuse to start Deadwood if it has a bind_address not in its
recursive_acl
