【赛迪网-IT技术报道】有两台邮件服务器分别为192.168.1.1(windows下主机名为b.test.cn)和192.168.1.3(linux下主机名为a.test.com)。
  在linux下配置DNS服务器,下面是配置过程中设置过的一些文件,
  /etc/hosts 文件的具体内容如下:
  # Do not remove the following line, or various programs   # that require network functionality will fail.   127.0.0.1 localhost.localdomain localhost fc4   192.168.1.3 a.test.com a   192.168.1.1 b.test.cn b   /etc/host.conf 文件:
  order hosts,bind   表示先用hosts文件做解析,在用DNS解析
  /etc/resolv.conf 文件:
  ; generated by NetworkManager, do not edit!
  search test.com   nameserver 127.0.0.1   search test.cn   nameserver 192.168.1.1   nameserver 61.144.56.100   /etc/named.conf 文件:
  //   // named.conf for Red Hat caching-nameserver   //   options {   directory "/var/named";
  dump-file "/var/named/data/cache_dump.db";
  statistics-file "/var/named/data/named_stats.txt";
  /*   * If there is a firewall between you and nameservers you want   * to talk to, you might need to uncomment the query-source   * directive below. Previous versions of BIND always asked   * questions using port 53, but BIND 8.1 uses an unprivileged   * port by default.   */   // query-source address * port 53;
  };
  //   // a caching only nameserver config   //   controls {   inet 127.0.0.1 allow { localhost; } keys { rndckey; };
  };
  zone "." IN {   type hint;
  file "named.ca";
  };
  zone "test.com"IN {   type master;
  file "test.com";
  allow-update { none; };
  };
  zone "1.168.192.in-addr.arpa"IN {   type master;
  file "192.168.1.rev";
  allow-update { none; };
  };
  zone "test.cn"IN {   type master;
  file "test.cn";
  allow-update { none; };
  };
  zone "0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {   type master;
  file "named.ip6.local";
  allow-update { none; };
  };
  zone "255.in-addr.arpa" IN {   type master;
  file "named.broadcast";
  allow-update { none; };
  };
  zone "0.in-addr.arpa" IN {   type master;
  file "named.zero";
  allow-update { none; };
  };
  include "/etc/rndc.key";
  在/var/name/test.com 文件下:
  $TTL 86400   @ IN SOA a.test.com. root.a.test.com (
  42 ; serial (d. adams)
  3H ; refresh   15M ; retry   1W ; expiry   1D ) ; minimum   IN NS a.test.com.   IN MX 10 mail.test.com.   a IN A 192.168.1.3   mail IN A 192.168.1.3   //其中root.a.test.com的含义是管理员的邮箱
  /var/name/test.cn 文件下:
  $TTL 86400   @ IN SOA b.test.cn. root.a.test.com (
  42 ; serial (d. adams)
  3H ; refresh   15M ; retry   1W ; expiry   1D ) ; minimum   IN NS b.test.cn.   IN MX 10 mail.test.cn.   b IN A 192.168.1.1   mail IN A 192.168.1.1   /var/name/192.168.1.rev 文件下:
  $TTL 86400   @ IN SOA 1.168.192.in-addr.arpa. root.test.com. (
  1997022700 ; Serial   28800 ; Refresh   14400 ; Retry   3600000 ; Expire   86400 ) ; Minimum   IN NS a.test.com.   IN NS b.test.cn.   IN MX 10 mail.test.com.   IN MX 10 mail.test.cn.   3 IN PTR a.test.com.   3 IN PTR mail.test.com.   1 IN PTR b.test.cn.   1 IN PTR mail.test.cn.   然后用/etc/init.d/named restart重启DNS服务,在重启过程中,我曾经出现过好几次的错误,按照出错的提示,会提示是named.conf文件第几行出错的。或者提示在那些包含文件例如test.cn这些文件里面的问题,然后一个一个排除。
  最后还有一些nslookup的命令比较有用:
  set all用于显示使用nslookup工具这台机器上的DNS服务器的一些信息
  set type=any会显示完整信息包括域中邮件服务器和主从DNS服务器的名字和IP地址
  server 192.168.0.1更换查询的DNS服务器地址。
