DNS视图以及日志压力测试

1    访问控制列表 配置在/etc/named.conf文件的最顶端
    acl innct {
        192.168.1.0/24;
        127.0.0.0/8;
    };
    allow query { innct; };
    
2-    视图
named.conf

acl telecom {
    192.168.1.0/24;
    127.0.0.8;
};

acl unicom {
    192.161.14.0/24;
    127.0.0.8;
};

options    {
    directory "/var/named";
    allow-recursion {    innet; };
};
view telecom {
    match-clients { telecom; };
    zone "xingxing.com" IN {
        type master;
        file "telecom.xingxing.com.zone";
    };
    zone  "xx.com" IN {
        type master;
        file "xx.com.zone";
    };
};
view unicom {
    match-clients { unicom; };
    zone "xingxing.com" IN {
        type master;
        file "unicom.xingxing.com.zone";
    };
    zone  "xx.com" IN {
        type master;
        file "xx.com.zone";
    };
};

vim /var/named/telecom.xingxing.com.zone

$TTL 43200
@    IN     SOA     dns.xingxing.com.    root (
                    2
                    1H
                    10M
                    7D
                    1D)

mail        IN     A        192.168.1.5
na            IN     A     192.168.1.3

vim /var/named/iunicom/unicom.xingxing.com.zone
$TTL 43200
@    IN     SOA     dns.xingxing.com.    root (
                    2
                    1H

                    1D)
@             IN     NS       dns

dns         IN     A     192.168.1.5
mail        IN     A        192.168.1.5
na            IN     A     192.161.14.3

3-    启用dnsLog日志

vim /etc/named.conf
options {
    querylog yes;
    
}

测试

vim /etc/named.conf

logging {
    channel querylog {
    file "/var/log/named/bind_query.log" versions 5 size 10M; //模式为file，名称为log.msgs，保存3个版本，大小为10k滚动
    severity dynamic;    //日志级别
    print-time yes;//打印时间
    print-category yes;//打印种类
    print-severity yes;//打印级别
    };
    channel my_syslog {
    syslog local0;
    severity info;
    };
    category queries { querylog; };//查询日志
    category xfer-out { my_file; };//传输出去日志 dig -t axfs xingxing.com @192.168.1.1
    category update { my_syslog; };
};
