Named doesn't like the dynamic updates? #3

Closed steventblack closed 7 years ago

Restarting the DNS server seems to result in a torrent of error messages: writable file '/etc/zone/master/null.zone.file': already in use: /etc/zone/data/null.zone.file:3

the /etc/zone/data/null.zone.file:3 phrase seems to refer to this line of that file: file "/etc/zone/master/null.zone.file";

A very fast google on the issue seems to revolve around the deprecated support for a dynamically updating a master DNS file. The wildcard identifier (match everything) coupled with the explicit include of the ad-blocker.db file is probably causing some sort of friction. Need to sort it out so that it operates a bit smoother.

The issue at heart seems to be that all the different zones for the blocked domains in the configuration file ad-blocker.db referencing the same zone file named/etc/zone/master/null.zone.file is a prohibited configuration. Need to find a workaround which (hopefully) doesn't entail generating a copy of the zone file for each blocked domain.

Disallowing updates for the zone seems to have resolved the issue.

Need to change the line in named/etc/zone/data/null.data.file to disallow updates:

zone "null.zone.file" {
    type master;
    file "/etc/zone/master/null.zone.file";
    allow-transfer {none;};
    allow-update {none;};
    allow-query {any;};
};

Leaving issue open until this is ensured either through Synology's interface tool or via programmatic means.

Updated readme to include appropriate setting of "Limit zone updates".
