DNS问题（NIGHTMARES！）与BIND和Virtualmin

我有一个使用Virtualmin / Webmin的networking服务器（带有LAMP的Ubuntu 12.04）。 因为我刚刚从一个Cpanel系统移动，所以我正在configurationDNS的恶梦！

使用intoDNS.com，失败的报告是：

Mismatched NS records WARNING: One or more of your nameservers did not return any of your NS records. DNS servers responded ERROR: One or more of your nameservers did not respond: The ones that did not respond are: 123.123.123.123 213.251.188.141x Multiple Nameservers ERROR: Looks like you have less than 2 nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me. Missing nameservers reported by your nameserver You should already know that your NS records at your nameservers are missing, so here it is again: ns1.mydomain.com. sdns2.ovh.net. SOA record No valid SOA record came back! MX Records WWW A Record ERROR: I could not get any A records for www.mydomain.com! 

我的尝试的一步一步

在我的域名注册商（Namecheap）中，我将ns1.mydomain.com注册为域名服务器，指向正在运行bind9的我的web服务器的IP地址。 该域是使用DNS ns1.mydomain.com和sdns2.ovh.net 。 sdns2.ovh.net是一个辅助DNS服务器（SLAVE并指向我的web服务器的IP地址mydomain.com ）

• 多个IP的每个域名和路由到最快的可用服务器？
• 从子网使用ISP的名称服务器
• 我可以将大约30个DNS区域NS条目指向同一个两个IP地址吗？
• configuration错误的DNS /名称服务器？
• dynamicIP和MXlogging

networking服务器域名 ： mydomain.com

Webserver主机名 ： ns4000000.ip-123-123-123.net

networking服务器IP ： 123.123.123.123

在Virtualmin下，我编辑了默认的虚拟服务器模板，

• 新域的BIND DNSlogging： ns1.mydomain.com
• 主DNS服务器主机名： ns1.mydomain.com

接下来我使用该服务器模板创build了一个虚拟服务器

这是我所做的，但它仍然不工作！ 有任何想法吗？ 我被困了好几天，谢谢你的帮助！
