FreeBSDな生活

FreeBSDの6.3で添付のbindが9.3.4になった。もちろん、7.0-RELEASEもbindは9.3.4だ。
大きな特徴は、named.confで外向きと内向きの記述を書き分けられるようになったことだ。外向きは必要ないので、内向きのみ作ったnamed.confと合わせて正逆zoneファイルの例を下記に示しておく。

1.named.conf

options {
directory       "/etc/namedb";
pid-file        "/var/run/named/pid";
dump-file       "/var/dump/named_dump.db";
statistics-file "/var/stats/named.stats";
forwarders {
210.188.224.10;
};
};
view "internal" {
match-clients { 192.168.1.0/24; 127.0.0.0/8; };
recursion yes;
zone "." {
type hint;
file "named.root";
};
zone "localhost" {
type master;
file "master/localhost.zone";
};
zone "0.0.127.IN-ADDR.ARPA" {
type master;
file "master/localhost.rev";
};
zone "fam.cx" {
type master;
file "slave/canal.zone";
allow-update { none; };
};
zone "1.168.192.in-addr.arpa" {
type master;
file "slave/canal.rev";
allow-update { none; };
};
};

2. localhost.zone

$TTL    86400
@             IN      SOA   uls.fam.cx.  root.uls.fam.cx.(
2005071701      ; Serial
3600            ; Refresh
900             ; Retry
3600000         ; Expire
3600 )          ; Minimum
IN      NS    uls.fam.cx.
localhost.    IN      A     127.0.0.1

3. localhost.rev

$TTL    86400
@             IN      SOA   uls.fam.cx.  root.uls.fam.cx.(
2005071701      ; Serial
3600            ; Refresh
900             ; Retry
3600000         ; Expire
3600 )          ; Minimum
IN      NS    uls.fam.cx.
1             IN      PTR   localhost.

4. 正引きzone file(canal.zone)

$TTL 3600       ; 1 hour
@             IN      SOA   uls.fam.cx.  root.uls.fam.cx.(
2006121601 ; serial
10800      ; refresh (3 hours)
3600       ; retry (1 hour)
3600000    ; expire (5 weeks 6 days 16 hours)
3600       ; minimum (1 hour)
)
IN       NS      uls.fam.cx.
IN       MX      10 uls.fam.cx.
uls            IN       A       192.168.1.5
www            IN       CNAME   uls
ftp            IN       CNAME   uls

5. 逆引きzone file(icanal.rev)

$TTL 3600       ; 1 hour
@             IN      SOA   uls.fam.cx.  root.uls.fm.cx.(
2006121602 ; serial
10800      ; refresh (3 hours)
900        ; retry (15 minutes)
3600000    ; expire (5 weeks 6 days 16 hours)
3600       ; minimum (1 hour)
)
IN NS   uls.fam.cx.
5                       IN PTR  uls.fam.cx.
