由于 Dnsmasq 不支持视图,我已安装并配置了 bind9。一切正常,但我注意到在特定条目上,我的绑定服务器没有返回与 Dnsmasq 相同的答案/响应。我该如何实现这一点?
这是我的 Dnsmasq 服务器的配置:
address=/override-url.example.com/54.210.175.6
这是来自我的 Dnsmaq 服务器的 DNS 响应:
$ dig @127.0.0.1 override-url.example.com
回复:
; <<>> DiG 9.9.5-3-Ubuntu <<>> @127.0.0.1 override-url.example.com
; (1 server found)
;; global options: +cmd
;; Got answer:

这是我的绑定配置和区域文件:
zone "override-url.example.com" {
type master;
file "/etc/bind/override-url.example.com";
};
区域文件:
$TTL 3600
$ORIGIN override-url.example.com.
@ IN SOA localhost. hostmaster.localhost.com. (
20140805 ; sn = serial number
86400 ; ref = refresh = 1d
900 ; ret = update retry = 15m
1209600 ; ex = expiry = 2w
3600 ; min = minimum = 1h
)
; we need at least 1 name server
IN NS
; override public ip with this address
IN A 54.210.127.53
当然,这是 bind 返回的数据,与上面的答案不匹配。我希望尽可能地匹配。

我应该对绑定区域文件进行哪些更改以使其看起来尽可能接近 dnsmasq 设置?
答案1
想通了,必须做出以下改变:
添加minimal-responses yes;
named.conf.options
并将区域文件更改为以下内容:
$TTL 3600
$ORIGIN override-url.example.com.
@ IN SOA override-url.example.com. hostmaster.override-url.example.com. (
20140805 ; sn = serial number
86400 ; ref = refresh = 1d
900 ; ret = update retry = 15m
1209600 ; ex = expiry = 2w
3600 ; min = minimum = 1h
)
; we need at least 1 name server
IN NS override-url.example.com.
; override public ip with this address
IN A 54.210.127.53
