测速模式和响应模式参数配置优先级问题

giveup commented 3 months ago

问题现象
和#https://github.com/pymumu/smartdns/issues/1790 类似，例如对于测速，共有三处地方可配置。全局 speed-check-mode none 端口 [-no-speed-check]：停用测速 域名规则 domain-rules /example.com/ -speed-check-mode none 在配置文档均有说明https://pymumu.github.io/smartdns/config/check-speed-mode/ 但是没有提到优先级。我的理解是域名规则优先级最高。使用的配置如下

全局 speed-check-mode none
端口 bind :54@lo  -no-speed-check
域名 domain-rules address /*.github.io/  speed-check-mode tcp:443,ping

root@AX6S:/etc/openclash# smartdns --cache-print  /etc/smartdns/smartdns.cache  | grep 'github.io'
domain: pymumu.github.io, qtype: 1, rcode: 0, ttl: 600, speed: -0.1ms, result: 185.199.108.153, 185.199.111.153, 185.199.109.153, 185.199.110.153
domain: pymumu.github.io, qtype: 65, rcode: 0, ttl: 600, speed: -0.1ms

从缓存结果来看都是-0.1，似乎测速并没有生效。类似的还有响应模式等参数的配置优先级。

运行环境

固件型号 OpenWrt 23.05.4
运营商
smartdns来源以及版本 smartdns 1.2024.v46.0.9
涉及的配置(注意去除个人相关信息)

重现步骤

上游DNS配置。
访问的域名。
github.io

信息收集

将/var/log/smrtdns.log日志作为附件上传(注意去除个人相关信息)。
如进程异常，请将coredump功能开启，上传coredump信息文件，同时上传配套的smartdns进程文件。
在自定义界面，开启设置->自定义设置->生成coredump配置，重现问题后提交coredump文件 coredump文件在/tmp目录下

建议开debug日志看看这个域名有没有命中规则

@PikuZheng 请问怎么看日志关键字

单看这个貌似只设置了 namerserver /github.io/oversea，没有针对这个域名设置测速规则

giveup commented 2 months ago

speed-check-mode none
bind :54@br-lan  -no-speed-check -no-dualstack-selection -force-aaaa-soa -group oversea
conf-file /etc/smartdns/custom.conf

custom.conf如下

serve-expired-ttl 604800
domain-rules /*.github.io/  speed-check-mode tcp:443,ping -response-mode fastest-ip

请问这样算正确设置吗？@PikuZheng

PikuZheng commented 2 months ago

serve-expired-ttl 604800\ndomain-rules /*.github.io/ speed-check-mode tcp:443,ping -response-mode fastest-ip

语法错

giveup commented 2 months ago

@PikuZheng 请问正确的语法是什么，我已经仔细查看说明文档配置，但是可能理解有误。想要达到的效果是，对于*.github.io域名，按照tcp 443端口进行测速，模式为最快IP。同时全局模式和第二端口关闭测速。

PikuZheng commented 2 months ago

（用手机回的打字比较慢

speed-check-mode none
domain-rules /*.github.io/ -nameserver oversea -speed-check-mode tcp:443 -response-mode fastest-ip

giveup commented 2 months ago

@PikuZheng 需要加上-nameserver oversea参数吗？我是基于端口分流的，下游客户端会把github.io会被转发给54端口，54端口已经设置为oversea组， oversea组配置如下

server-tls 223.5.5.5  -group oversea -exclude-default-group -subnet ecs-ip
server-tls 223.6.6.6  -group oversea -exclude-default-group -subnet ecs-ip
server-tls 1.12.12.12  -group oversea -exclude-default-group -subnet ecs-ip
server-tls 120.53.53.53  -group oversea -exclude-default-group -subnet ecs-ip

我看配置文档的说明

nameserver | 指定域名使用 server 组解析 | 无 | nameserver /domain/[group\|-], group 为组名，- 表示忽略此规则，配套 server 中的 -group 参数使用 | nameserver /www.example.com/office

这个是把指定域名使用指定的组，但是我已经按端口分流，应该不需要再按域名分流。

PikuZheng commented 2 months ago

但是我已经按端口分流，应该不需要再按域名分流。

正确的，不用再加了

giveup commented 2 months ago

@PikuZheng 所以我这配置就是正确的吗？那日志看不出来有测速的地方可能是什么问题呢？

conf-file /etc/smartdns/custom.conf

此处不应有 -no-speed-check ，这个会导致所有测速规则跳过

@PikuZheng 也就是优先级上，全局>端口>大于Domain rule。之所以使用domain rule的方式来配置是因为只有少数域名是频繁访问的，开启测速效果可能会更好，如果整个端口都开启测速，可能会导致dns查询需要较长时间才能返回结果。

反了，全局 < domain rule < -no-speed-check 全局和domain rule都是用来选择一种测速方法 -no-speed-check是强制不测速，而不是选择一种测速方法
