我在软件层使用由 dnsmasq 提供支持的 Raspberry Pi3 设置 Wi-Fi 接入点 (AP)。Wi-Fi AP 出现，设备可以毫无问题地加入网络。然而，DNS 查找失败，我已经确定原因是 dnsmasq 无法在 wlan0 接口上抢占 bind9/named，尽管必要的配置已经到位。
Raspian 的版本是：Release 10 (Buster)
以下是相关的配置文件。
dnsmasq.conf
# The Wi-Fi interface configured for static IPv4 addresses
interface=wlan0
# Explicitly specify the address to listen on
listen-address=192.168.1.2
# Bind to the interface to make sure we aren't sending things elsewhere
bind-interfaces
# Forward DNS requests to the Google DNS
server=8.8.8.8
# Don't forward short names
domain-needed
# Never forward addresses in non-routed address spaces
bogus-priv
# Assign IP addresses between 192.168.1.50 and 192.168.1.150 with a 12 hour lease time
dhcp-range=192.168.1.50,192.168.1.150,12h
dhcpcd.conf
hostname
duid
option rapid_commit
# A list of options to request from the DHCP server.
option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes
# Most distributions have NTP support.
option ntp_servers
# A ServerID is required by RFC2131.
require dhcp_server_identifier
# Generate Stable Private IPv6 Addresses instead of hardware based ones
slaac hwaddr
# A hook script is provided to lookup the hostname if not set by the DHCP
# server, but it should not be run by default.

interface wpan0

nodhcp6
interface eth0

有人可以帮忙吗 - 特别是为什么bind-interfacesdnsmasq 中的配置没有按预期产生任何效果？Bind9 配置为在 dnsmasq 之后启动，并且在所有接口上具有默认绑定行为......但我的期望是它应该排除任何已被其他服务专门绑定的接口。
