把DNS请求日志转发到syslog服务器去

把DNS请求日志转发到syslog服务器去

在vim /etc/named.conf里配置的内容

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
        channel syslog_channel {
        syslog DNS-LOG;
        severity debug;
        print-time yes;
        print-category yes;
        print-severity yes;
        };
        category default {
        syslog_channel;
        };
};

zone "baidu.com" {
    type forward;
    forwarders {10.127.1.8; };
    forward only;
};


zone "qq.cn" {
    type forward;
    forwarders {10.127.1.8; };
    forward only;
};

在rsyslog服务里的配置项，最下面vim /etc/rsyslog.conf

# remote host is: name/ip:port, e.g. 192.168.0.1:514, port optional
#*.* @@remote-host:514
#将BIND的DNS请求信息发送给日志平台
DNS-LOG.* @@10.5.5.5:514
# ### end of the forwarding rule ###

重启rsyslog服务

systemctl restart rsyslog
