NoWayda commented 7 months ago

问题现象
简要描述问题出现的现象

运行环境

固件型号
运营商
smartdns来源以及版本
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。

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

双栈优选是打开的，测速响应都是默认的~

当smartdns未以root权限运行时，出现此问题（linux的限制）

能求个openwrt root权限运行smartdns的设置或者代码吗

安装运行的问题，不是配置问题。建议卸载后下载release版安装

卸载重装release版本无效卸载重装openwrt软件源42版本后无效。请问还有其他方法吗？

pymumu commented 7 months ago

你的openwrt没有ping ipv6的权限，所以smartdns自动关闭ipv6特性了。

大佬有没有什么解决方案实在不想重刷了

pymumu commented 7 months ago

先看openwrt路由器有没有获取到ipv6的地址吧。

NoWayda commented 7 months ago

先看openwrt路由器有没有获取到ipv6的地址吧。

确定获取到了。纯ipv6网站能访问。ipv6-test 10分完美。openwrt ping6也没问题。

NoWayda commented 7 months ago

哦有个细节不知道是不是影响。我是openclash接管所有然后上游smartdns。openclash IPv6是tproxy。

pymumu commented 7 months ago

你路由器中无法ping通ipv6，导致smartdns禁用了ipv6功能。

openwrt,PC客户端都可以ping通ipv6

NoWayda commented 7 months ago

我搜索了一下类似问题，可能这个issue跟我遇到的差不多。 https://github.com/pymumu/smartdns/issues/1589

并且有一些-0.1ms的我在openwrt或者客户端里是能ping通的

pymumu commented 7 months ago

发debug日志把，启动的时候的。

说了，你这个问题是smartdns检测到ipv6不工作，自动禁用了ipv6相关的功能。

PikuZheng commented 7 months ago

我感觉更像是没有以root权限启动。如果是 openwrt.ai 出来的固件，可能部分版本会有这个问题（插件争抢/冲突？）

额，咱俩开头关于IPv6的info一样。然后你看看，是不是所有的IPv6的ip都是-0.1ms

pymumu commented 7 months ago

看你们是不是关闭了测速，关闭测速后，是不会再发起测速的。日志里面的speed也就是-0.1ms

但这不代表IPv6不能使用。

NoWayda commented 7 months ago

没有关闭，且ipv4测速正常，只是所有6是这样的。屏幕截图 2024-01-22 111419

PikuZheng commented 7 months ago

应该是两个问题

黑洞，但ipv6是可用且正常的

speed-check-mode none
但是
domain-rules /domain-set:mainland/ -speed-check-mode ping -nameserver mainland

---- 又试了一次 speed-check-mode ping 现象依旧

pymumu commented 7 months ago

ping 2001::这个是检查有没有权限的，不需要是否能通。

只有两个原因：

配置没有开启测速。
ping没有权限。

目前看只有第一个原因。

PikuZheng commented 7 months ago

root@OpenWrt:~# cat /var/etc/smartdns/smartdns.conf |grep speed speed-check-mode none 但是 domain-rules /domain-set:mainland/ -speed-check-mode ping -nameserver mainland

我检查了我的配置。目前确定在这样设置时，domain-rules的ping对ipv6不起作用其他是我配置问题（多设备同步配置出问题了

我知道是怎么回事了，高级设置里面测速是关闭的，这时候在域名规则列表中单独设置测速是无效的~

我也碰到了类似的情况。全局测速关闭了，domain-rules里写了测速，然后同一个域名的IPv4有测速，IPv6没有测速
