基于redhat as5的squid＋named.caching

三年前搞过一个基于debian的高级网关路由，使用的是iptable+squid+apche+pptpd+bind

实现了透明代理，简单访问web页面加速，dns解析加速，访问控制和VPN呼入。

 

现在我在的公司暂时还没有自己的dns，所以我使用redhat 简单架设了一个squid+bind cache服务。

 

由于前些日子已经在内网部署了yum服务，安装比较简单

yum install caching-nameserver

yum install squid

 

 

 /etc/named.caching-nameserver.conf

options {
        listen-on port 53 { 127.0.0.1; };
        listen-on-v6 port 53 { ::1; };
        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";
        query-source    port 53;
//      query-source-v6 port 53;
max-cache-size 40M;
max-cache-ttl 86400;
max-ncache-ttl 166000;

allow-query     { localhost;192.168.1.0/24 };
recursion yes;
//forwarders {202.98.96.68;};
forwarders {61.139.2.69;202.98.96.68;};
forward only;
