BIND 9 の文

この項では、BIND 8 と BIND 9 の文の相違点について説明します。

Controls 文

unix が ndc のデフォルトであり、引数のすべてがコンパイルされます。inet が rndc の唯一のオプションであり、この場合、何もコンパイルされません。


  Syntax
     controls {
       [ inet ip_addr
         port ip_port
         allow { address_match_list; }; ]	OK
       [ unix path_name
         perm number
         owner number
         group number; ]			Not Implemented
     };

ロギング構文は大幅に変更されました。named.conf オプションのリストは、「named.conf のオプション」を参照してください。

Zone 文

BIND 8 の named.conf マニュアルページに示されているゾーン文の構文は、次を除いた大部分が BIND 9 でサポートされます。


  [ pubkey number number number string; ]	Obsolete
  [ check-names ( warn | fail | ignore ); ]	Not Implemented

ACL 文

BIND 9 で変更なく機能します。


  Syntax
     acl name {
       address_match_list
     };

Key 文

BIND 9 で変更なく機能します。


  Syntax
     key key_id {
       algorithm algorithm_id;
       secret secret_string;
     };

Trusted-Keys 文

変更なく機能しますが、この文を使用するコードは BIND 9.2.4 で使われなくなりました。


  Syntax
     trusted-keys {
       [ domain_name flags protocol algorithm key; ]
     };

Server 文

support-ixfr は廃止されましたが、次のオプションのすべては BIND 9 で変更なく機能します。transfer-format のデフォルトは変更されました。


  Syntax
     server ip_addr {
       [ bogus yes_or_no; ]
       [ transfers number; ]
       [ transfer-format ( one-answer | many-answers ); ]
       [ keys { key_id [ key_id ... ] }; ]
       [ edns yes_or_no; ]
     };

Include 文

BIND 9 で変更なく機能します。


  Syntax
     include path_name;
