未绑定服务器未响应unbond客户端API所做的dns查询

Question

我正在尝试测试dnsmasq和未绑定服务器。当我从机器"Y“发出getaddrinfo()请求时，我从dnsmasq服务器机器"X”获得dns查询响应。但是，当我通过关闭dnsmasq并打开机器"X“上的未绑定服务器从未绑定客户端API发送dns查询时，我没有看到任何dns响应/解析。

我已经从源代码中安装了未绑定服务器，并解决了它对"X“上RHEL5的依赖关系。

我将机器"X“上的未绑定服务器启动为：

未绑定的-c /usr/local/etc/ unbound /un界.local

而且正常的启动没有任何错误。

unbound.conf的配置是：

server:
        verbosity: 1
## Specify the interface address to listen on:
        interface: xxx.xxx.xxx.xxx
## To listen on all interfaces use:
#       interface: 0.0.0.0
        do-ip4: yes
        do-ip6: yes
        do-udp: yes
        do-tcp: yes
        do-daemonize: yes
        access-control: 0.0.0.0/0 allow
## Other access control examples
#access-control: 192.168.1.0/24 action
## 'action' should be replaced by any one of:
#deny (drop message)
#refuse (sends  a  DNS  rcode REFUSED error message back)
#allow (recursive ok)
#allow_snoop (recursive and nonrecursive ok).
## Minimum lifetime of cache entries in seconds.  Default is 0.
#cache-min-ttl: 60
## Maximum lifetime of cached entries. Default is 86400 seconds (1  day).
#cache-max-ttl: 172800
## enable to not answer id.server and hostname.bind queries.
        hide-identity: yes
## enable to not answer version.server and version.bind queries.
        hide-version: yes
## default is to use syslog, which will log to /var/log/messages.
use-syslog: yes
## to log elsewhere, set 'use-syslog' to 'no' and set the log file location below:
#logfile: /var/log/unbound
python:
remote-control:
        control-enable: no
## Stub zones are like forward zones (see below) but must only contain authority server (no recursive servers)
#stub-zone:
#        name: "my.test.com"
## Note for forward zones, the destination servers must be able to handle recursion to other DNS server
## Forward all *.example.com queries to the server at 192.168.1.1
#forward-zone:
#        name: "example.com"
#        forward-addr: 192.168.1.1
## Forward all other queries to the Verizon DNS servers
forward-zone:
        name: "."
## Level3 Verizon
        forward-addr: 4.2.2.1
        forward-addr: 4.2.2.4

请告诉我，如果我在哪里出错，还想知道dnsmasq服务器是否实现了线程/叉子进程来处理查询，我们能在/etc/dnsmasq.conf中设置相同的子进程吗？

Answer 1

必须在unbound.conf中添加配置

access-control: <IP of client machine>/8 allow_snoop

Answer 2

.You必须将您的ip添加到该列表中。

访问控制: /8 allow_snoop

Dnsmasq实现了一个进程model.So --他将为每个新请求分叉一个新进程，但是unbound具有一个静态计数，它是在处理所有后续请求时生成的进程数，而且您还可以在未绑定的情况下使用线程。
