namedを
[root@host ~]# /etc/rc.d/init.d/named stop しても
named を停止中:
のままとなり[OK]表示がされないため、Johannさんが実施されたようにkillでnamedのプロセスを停止させた後、yum -y removeで"bind""caching-nameserver""install bind-chroot"を削除しました。
(実際にはbindのみですべてアンインストールされたようにも見えたけど気のせいですかね？)
で、再度上記3つをyum -y installでインストールしnamed.confを以下のように設定し直しました。
// generated by named-bootconf.pl
options {
directory "/var/named";
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
allow-query{
127.0.0.1;
192.168.1.0/24;
};
allow-recursion{
127.0.0.1;
192.168.1.0/24;
};
allow-transfer{
127.0.0.1;
192.168.1.0/24;
};
forwarders{
192.168.1.1;
};
};
//
// a caching only nameserver config
//
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
logging {
category lame-servers { null; };
};
zone "." IN {
type hint;
file "named.ca";
};
zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update { none; };
};
include "/etc/rndc.key";
zone "ispiron-web.com" IN {
type master;
file "inspiron-web.com.db";
allow-update { none; };
};
zone "1.168.192.in-addr.arpa" IN {
type master;
file "1.168.192.in-addr.arpa.db";
allow-update { none; };
};
で、val99様よりご指示頂いたように、以下を実施しました。

このまま以下を実施すると、
[root@host ~]# /etc/rc.d/init.d/named status
rndc: connect failed: connection refused
[root@host ~]# /etc/rc.d/init.d/named stop
named を停止中:
[root@host ~]# /etc/rc.d/init.d/named start
named を起動中: [ OK ]
[root@host ~]# /etc/rc.d/init.d/named status
rndc: connect failed: connection refused
[root@host ~]# /etc/rc.d/init.d/named restart
named を停止中:
named: 既に実行中です[root@host ~]# /etc/rc.d/init.d/named status
rndc: connect failed: connection refused
となります。
また、Windowsクライアントマシンからnslookupも以下となり、以前と変わりません。
