使用阿里dns，不定时出现Connection reset by peer #1712

Open giveup opened 3 months ago

giveup commented 3 months ago

问题现象
如日志显示，使用阿里dns作为上游，不定时出现Connection reset by peer和500错误，考虑到这是阿里的服务，不太可能出现宕机和被干扰的问题。（另一个证据就是，使用阿里dot时，没有出现这种异常）

运行环境

  1. ax6s

  2. 运营商
    联通

  3. smartdns来源以及版本 1.2024.v45.0.11-OpenWrt-openssl3

  4. 涉及的配置(注意去除个人相关信息)

    server-https https://223.5.5.5/dns-query  -no-check-certificate -http-host dns.alidns.com -group domestic -subnet ****

从 #1673 起，我就开始从家里的宽带监视阿里doh可用性，从未有错误（联通） image 目前还是考虑单个ip查询超出阿里配额上限，被黑名单

giveup commented 3 months ago

@PikuZheng 使用dot时并不会出现这种错误，难道针对IP的策略还区分doh和dot？ 除了500错误偶尔还会出现400

建议不时的ping一下223.5.5.5，观察ttl会不会变化。 @pymumu 有没有可能是到阿里的数据中心发生跳跃，但是smartdns在尝试保持https链路

PikuZheng commented 3 months ago

问下 楼主用的哪里的联通

giveup commented 3 months ago

根据阿里dns官网的说法，我所在地区是有阿里dns的节点的，无论是稳定性还是延迟都应该是比较优秀的。 目前手工ping，挂机一段时间看看ttl如何。

发一下配置看看。

去掉server-https的subnet配置看看。

我也用了edns-client-subnet 是这个问题吗？ 我先去掉试试

之前缓存数量开的大 这种情况就很多log 我以为是请求太多风控了呢

lalasou commented 3 months ago

跑了试试 没有错误了 貌似真是这个subnet问题 我在用两天试试

giveup commented 3 months ago

@pymumu 用release版跑了两天，暂时没看到类似的错误。还有个变量是清除缓存了，之前用的每夜版有9000多个域名缓存，现在只有不到2000个。其他的配置保持不变。关于风控，我觉得不太可能，因为之前用dot时，也是这么多缓存，也有配置edns。但是没有出现这种错误。

发现不止是阿里dns，使用smartdns作为https服务时，在阿里出现500或connect reset问题的同时，smartdns的下游也会出现连接问题

从 #1673 起，我就开始从家里的宽带监视阿里doh可用性，从未有错误（联通） image 目前还是考虑单个ip查询超出阿里配额上限，被黑名单

使用release版，且使用dot时，也会出现类似的错误。

我最新源码编译的，阿里DNS的所有查询方式(DoH/DoT/HTTPS等)我都没问题，相反我腾讯DNS前不久开始到现在却是经常Connection reset by peer，也是DoH/DoT/HTTPS等都报错

难道开始用 360 的 dot 和 doh （

台湾dns 也挺好

指个路？ 我去看看延迟和解析结果怎么样 （

PikuZheng commented 1 month ago

考虑和 #1730 是相同问题？因为我测试过从路由器断开https查询后，smartdns重连端口号是不变的

@PikuZheng 根据使用其他支持doh和doh3的rust版的smartdns测试，可能有两个原因。 1:阿里dns风控的原因。 2:运营商干扰加密dns（仅限doh/doh3/doq）。 两种版本都会出现不明原因的查询故障。dot一切正常。 https://github.com/mokeyish/smartdns-rs/issues/307#issue-2346878912

上面提到有 Http 长链接的问题，基于 QUIC 的 H3 应该不会有长连接问题。@giveup 你真有用 DoH3 吗? Rust 版的 DoH3 有两种写法，

server-h3 223.5.5.5

考虑到与 C 版兼容 luci 界面这样也是支持的

rust版的doh3和doq配置文档还是我提的PR，我不至于连这个都搞错。
