設定 DNS log

在 "/var/named/etc/namedb/named.conf"裡加入這段

logging {
  channel querylog {
    file "/var/log/query.log/var/named/var/log/query.log" versions 5 size 50m;
    print-category yes;
    print-severity yes;
    print-time yes;
  };
  category queries { querylog; };
};

然後
rndc reload
rndc querylog
即可


補充：bind的權限不足以寫入/var/log
