如何在 DNS 转发文件中添加两个名称服务器？

  • 772

这是我的 DNS 转发文件，当我想将它作为服务运行时它给了我错误。我认为这是一个语法错误，但不知道如何纠正它？

$TTL 86400

这是错误：

    关键错误是multiple RRs of singleton type。简而言之，对于该区域，您不能拥有多个 SOA 记录。您需要删除：

    @   IN  SOA     ns2.sudia.com. root.sudia.com. (
                                              3           ;Serial
                                              3600        ;Refresh
                                              1800        ;Retry
                                              604800      ;Expire
                                              86400       ;Minimum TTL
)

    因此，您的示例区域的更新版本将是：

    前任。var/named/fwd.sudia.com.db

    $TTL 86400
@   IN  SOA     ns1.sudia.com. root.sudia.com. (
                                              5           ;Serial
                                              3600        ;Refresh
                                              1800        ;Retry
                                              604800      ;Expire
                                              86400       ;Minimum TTL
)
