又一个可以在其外面套上一层socks proxy的dns代理程序：dnsforwarder-by-regret1537

在mac机器上。
git clone https://github.com/regret1537/dnsforwarder dnsforwarder-by-regret1537
cd dnsforwarder-by-regret1537
./configure
make
(会在当前目录下，生成可执行文件dnsforwarder）
nano default-en.config
其内容如下：
LogOn false
LogFileThresholdLength 102400
LogFileFolder
LocalInterface 127.0.0.1
LocalPort 53
OpenLocalTCP true
PrimaryServer TCP
TCPServer 8.8.4.4,8.8.8.8
TCPProxy 127.0.0.1:1080
UDPServer 208.67.220.220
UDPFilter true
UDPBlock_IP 243.185.187.39,46.82.174.68,37.61.54.158,93.46.8.89,59.24.3.173,203.98.7.65,8.7.198.45,78.16.49.15,159.106.121.75

OverrideTTL -1

ReloadCache false
OverwriteCache false
DisabledType

RefusingResponseCode 0
DomainStatistic false

然后运行：
sudo ./dnsforwarder -f default-en.config
不要关闭此terminal窗口。

看见配置文件里面的TCPProxy 127.0.0.1:1080了吗？这个dnsforwarder-by-regret1537其实是修改自https://github.com/holmium/dnsforwarder ，但是https://github.com/holmium/dnsforwarder/blob/6/default.config和https://github.com/holmium/dnsforwarder/blob/6/default.en.config里面均没有TCPProxy这一项。但是https://github.com/regret1537/dnsforwarder/blob/5/default.config里面有TCPProxy这一项。所以我们可以替dnsforwarder-by-regret1537套一层socks proxy，比如ss.

实际使用例子：
sudo wg-quick up wg0 

sudo networksetup -setdnsservers "Wi-Fi" 127.0.0.1
cd ~/dnsforwarder-by-regret1537 && sudo ./dnsforwarder -f default-en.config

此文https://briteming.blogspot.com/2019/07/dns-querysocks.html又要添上一员了。

ps.其实https://github.com/holmium/dnsforwarder/blob/5/default.config里面有TCPProxy这一项，所以https://github.com/holmium/dnsforwarder的v5版也是支持TCPProxy这一项的。
