Re: [Samba] DNS logging for TLD queries?




Yes,, this is very welkom! Thanks Dennis!! 

I've "Debianized" this a bit also. 
It now matched the "adm" administrative group that is allowed to read the logs. 

if [ ! -d /var/log/bind ]; then
  install -d /var/log/bind -m 0750 -o bind -g adm
fi

if [ ! -e /etc/logrotate.d/bind ]; then
cat << EOF >> /etc/logrotate.d/bind
/var/log/bind/*.log {
  daily
  missingok
  rotate 7
  compress
  delaycompress
  notifempty
  create 0640 bind adm
  postrotate
    systemctl reload bind9 > /dev/null
  endscript
}
EOF
fi


And configure it as shown on the site. 


Greetz and Happy New Year Everybody.
