监听的端口指定服务器组之后，只能返回一个IP地址 #1685

Closed InspoOnU closed 4 months ago

InspoOnU commented 4 months ago

问题现象
OpenWRT中分别设置SmartDNS的第一/第二服务器的监听端口为52853/52653，其中第二服务器指定服务器组，设置max-reply-ip-num 64 分别使用nslookup查询结果如下：

日志里显示上游返回了多IP，但是nslookup里只有一个： smartdns.log

去掉bind里的group参数就能正常返回多IP

第二服务器的 cache-size， speed-test 和 response-mode 分别是怎么设置的？ 用第二服务器连续查询一个域名两次，都是只有一条结果吗？

cache-size 131072 speed-test none response-mode fastest-response 没有看到单独设置第二服务器的cache-size， speed-test 和 response-mode。连续查询结果依旧。目前发现去掉bind里的group参数才能返回多个IP

PikuZheng commented 4 months ago

那很有可能是最快应答的上游只给出了一个结果

应该不是，我先用上游查询，返回的是多IP。再用SmartDNS查询，还是只返回一个

奇怪的是日志里显示上游返回了多个IP，但是nslookup里只有一个 smartdns.log

PikuZheng commented 4 months ago

我想了想，关了缓存且关了测速的确是只返回一个ip。可以考虑修改response-mode fastest-response或去掉 -no-cache（二选一，不能同时

查询的服务器（52653）没有开启-no-cache，修改response-mode问题依旧。我测试了只能去掉-group才能解决

我的错。。。。 有没有可能是测速失败，可以试试改成不测速

配置文件里就是speed-check-mode none，而且还用了-no-speed-check

PikuZheng commented 4 months ago

大致试了一下，bind 指定group时，好像无论如何都会跳过测速，应该是跳了某些全局规则（openwrt的“第二服务器”遗留问题？）@pymumu

pymumu commented 4 months ago

你所有bind的端口，都关闭了测速，第二服务器还关闭了缓存。 这种情况下，smartdns会将返回上游最快的响应，指定了不缓存的查询，将不会对结果进行缓存。

也就是你上游服务器可能就返回了一个IP地址给你，所以smartdns也只会返回一个地址

你可以打开log看具体上游返回了多少地址。

@PikuZheng 另外bind 指定-group查询，没有问题，不会跳过测速，除非显式指定跳过测速，例如楼主的配置。

试过了。用这个配置

speed-check-mode ping
dualstack-ip-selection no
response-mode fastest-response
cache-persist no
bind [::]:52653  -group secure
max-reply-ip-num 64
server 上游:53 -group secure

理论上单一上游且fastest-response，应该是将上游结果原样返回的。但上游给出多个结果，smartdns只选用了第一个，和楼主的日志一致。

我这不复现，你发一下查询baidu的时候的log。

另外，你更换下上游为国内的看看，查询baidu的时候。

另外，你更换下上游为国内的看看，查询baidu的时候。

我发现正式版2024.02.08确实没有这个问题，测试版45.0.6.1/45.0.5.1就会出现 测试版是这个：https://github.com/PikuZheng/smartdns/releases/download/1.2024.v45.0.6-OpenWrt-openssl3/smartdns_1.2024.v45.0.6-1_aarch64_cortex-a53.ipk 可能是最新的bug或者编译的问题吗？

我测试的是最新代码。

刚确认了一下，https://github.com/PikuZheng/smartdns/releases/tag/1.2024.v45.0.6-OpenWrt-openssl3会出现问题，https://github.com/pymumu/smartdns/releases/tag/Release45则不会。
