DNS日志记录通道问题

Question

我已经用日志通道配置了DNS服务器，但日志仍然在写入/var/ log /message文件。

options {

// Default zone file directory for this dns server
directory "/var/named";

// Who can perform queries against this dns server and get answers  (default: any)
allow-query { any; };

// Do we permit recursion for our internal hosts, and retrieve data from the cache for them? (default: no)
recursion yes;

listen-on { any; };

// Who can get entire zone files from this dns server (default : none)
allow-transfer {
127.0.0.1;
10.10.100.3;
};

// How many recursive clients does this dns support per second? (the default is 1000)
recursive-clients 100;

// Do we notify zone changes? Prevent DoD attacks (default: no)
notify yes;

// specifies which hosts are allowed to get answers from the cache (default: any)
allow-query-cache { any; };

// Does this server using two or more master servers? (default: yes)
multi-master yes;

// sets the maximum time (in seconds) for which the server will cache negative (NXDOMAIN) answers
max-ncache-ttl 300; //5min

// Hide version number (default: "")
version "";

// bombing sources add here (default: none)
blackhole { none; };
};

logging {
channel bindlog {
file "/var/log/querylog" versions 3 size 5m;
print-time yes;
print-category yes;
print-severity yes;
};
category xfer-out { bindlog;};
category xfer-in { bindlog;};
category security { bindlog;};
};

// we are the master server for gani.com
zone "gani.com" IN {
type master;
file "master/gani.com.frwd.db";

};

zone "100.10.10.in-addr.arpa" IN {
type master;
file "master/gani.com.rev.db";

};

/var/log/messages通常由syslog守护进程管理，因此很可能您的绑定配置了默认的syslog通道进行日志记录(请参阅“绑定9管理员参考手册”6.2.10.1节)。在测试中，即使：

logging {
  category default { default_debug; };
  ...
};

一些绑定启动消息仍被发送到syslog (通过Mac上的MacPorts获得绑定9.10 )，但我不确定您在syslog中看到了哪些日志，以及它们为什么会出现问题。
