Konfiguration af DNS daemon foregår i /Library/Server/named/named.conf

Nederst i filen, før linien med }; indsættes include "/Library/Server/named/adList.conf"; som vist her:

       };
include "/Library/Server/named/adList.conf";
};

filen /var/named/adList.conf genereres af scriptet /usr/local/bin/getAdBloc.sh

Indhold af scriptet findes her:

#!/bin/bash

# Make sure the working directory is the same as where the script is located.
cd "$(dirname "$0")"

curl -s "http://pgl.yoyo.org/adservers/serverlist.php?hostformat=bindconfig;showintro=0;mimetype=plaintext" -o "/usr/local/bin/adList.conf"
cat adList.conf | grep ^zone > /Library/Server/named/adList.conf

serveradmin stop dns >/dev/null 2>&1 
sleep 3
serveradmin start dns >/dev/null 2>&1

# script returns exit: 127 when run by launchd, without the next line !?
exit 0

Der skal bruges en fil der hedder /Library/Server/named/null.zone.file

FIlen skal indeholde dette :

; DNS NULL Zone File for host filtering
;
; - point all addresses to localhost
;

$TTL    86400   ; one day

@       IN      SOA     ns0.example.net.      hostmaster.example.net. (
                        2002061000       ; serial number YYMMDDNN
                        28800   ; refresh  8 hours
                        7200    ; retry    2 hours
                        864000  ; expire  10 days
                        86400 ) ; min ttl  1 day
                NS      ns0.example.net.
                NS      ns1.example.net.
                A       127.0.0.1
*               IN      A       127.0.0.1

For at automatisk at få opdateret AdBlock listen oprettes filen /Library/LaunchDaemons/net.update.dns.adblock.list.plist

Indhold af filen findes her:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC -//Apple Computer//DTD PLIST 1.0//EN http://www.apple.com/DTDs/PropertyList-1.0.dtd >
<plist version="1.0">
<dict>
        <key>Label</key>
        <string>net.update.dns.adblock.list</string>
        <key>ProgramArguments</key>
        <array>
                <string>./getAdBloc.sh</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
        <key>StartCalendarInterval</key>
         <dict>
           <key>Hour</key>
           <integer>5</integer>
           <key>Minute</key>
           <integer>0</integer>
           <key>Weekday</key>
           <integer>4</integer>
         </dict>
        <key>WorkingDirectory</key>
        <string>/usr/local/bin</string>
</dict>
</plist>

FIlen loades ved hver boot, og kan loades og enables manuelt med denne kommando:

sudo launchctl load -w /Library/LaunchDaemons/net.update.dns.adblock.list.plist

Hvis det ønskes at opdateringer ikke skal køre automatisk mere bruges denne kommando:

sudo launchctl unload -w /Library/LaunchDaemons/net.update.dns.adblock.list.plist

Hold øje med datering på filen /Library/Server/named/adList.conf for at se om den opdateres som ønsket.
