Всем привет.
Появилась задачка поднять DNS на BIND с возможностью фильтрации доменов с плохим рейтингом(Порно итд) и дальнейшим его резольвом на нужный IP где будет поднят сервер с апачем и нужным ответом. Что то на подобие OpenDNS.
Поднял CentOs7: для теста VM 2CPU/2GB RAM/50GBHDD
uname -a Linux dnshole.getinf.com 3.10.0-327.13.1.el7.x86_64
acl "trusted" {any;};
options {
listen-on port 53 { any; };
listen-on-v6 port 53 { any; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
allow-query { trusted; };
recursion yes;
bindkeys-file "/etc/named.iscdlv.key";
managed-keys-directory "/var/named/dynamic";
pid-file "/run/named/named.pid";
session-keyfile "/run/named/session.key";
};
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";
include "/etc/named/named.conf.local";
include "/etc/named/blackhole/spywaredomains.zones";
Файл spywaredomains.zones содержит базу доменов 2000+ в таком формате:
zone "cutheatergroup.cn" {type master; file "/etc/namedb/blockeddomain.hosts";};
zone "dionneg.com" {type master; file "/etc/namedb/blockeddomain.hosts";};
zone "delzzerro.cn" {type master; file "/etc/namedb/blockeddomain.hosts";};
zone "lupytehoq.com" {type master; file "/etc/namedb/blockeddomain.hosts";};
zone "vipprojects.cn" {type master; file "/etc/namedb/blockeddomain.hosts";};
zone "douate.com" {type master; file "/etc/namedb/blockeddomain.hosts";};
zone "hhj3.cn" {type master; file "/etc/namedb/blockeddomain.hosts";};
zone "hryspap.cn" {type master; file "/etc/namedb/blockeddomain.hosts";};
zone "iebar.t2t2.com" {type master; file "/etc/namedb/blockeddomain.hosts";};
zone "allindiapoint.com" {type master; file "/etc/namedb/blockeddomain.hosts";};
И так далее 2000+

Но если в файле spywaredomains.zones уменьшить количество зон до 50 к примеру то все будет ОК:

Но как видно по таймаутам DNS всё равно работает медленно хоть и резольвит как задумано.
Были подозрения на кеш но игра с параметром кеша в named.conf ничего не дала.
За основу брал данную статью Список доменов сливал ТУТ
Буду очень благодарен за ваши советы и помощь.
