Dear list, Is there a way of using dnssec-lookaside and forcing bind not to maintain a managed-keys-zone for certain views? Or allowing it to start up if the files are missing for some views? I have within my named.conf this view, designed to hide bind.version and so forth from the world at large:
view "external-chaos" chaos {
match-clients { !trusted; };
allow-query { none; };
zone "." { type hint; file "/dev/null"; };
};
The 'trusted' acl is just a list of my local networks.
However, this seems to cause bind to fail to restart cleanly, as bind
never generates any managed-keys-zone file for this view. Now, I can
work around this by deleting all of the managed-keys-zone files from the
working directory every time I need to restart named, but that's not ideal.
Cheers,
Matthew
