V5.4.1: 内置DNS查询失败(empty response)。 #2517

Closed mega-optimus closed 1 year ago

mega-optimus commented 1 year ago

你正在使用哪个版本的 V2Ray？

V5.4.1

你的使用场景是什么？

"domainStrategy": "IpOnDemand"

Chrome -> [socks5] -> V2Ray -> [VMess/QUIC]

embedded DNS pointing to localhost or [8.8.8.8], both result in "empty response"

你看到的异常现象是什么？

[Info] features/routing/dns: resolve ip for raw.githubusercontent.com > empty response

你期待看到的正常表现是怎样的？

DNS resolves correctly.

========== Update: Removing this line in "dns" section solves the problem, anybody knows why? "fallbackStrategy": "Disabled"

========== Update: changing "router" rule like this, moves baidu.com from [direct] to [proxy], which is unexpected. "code": "cn" => "countryCode": "cn",

========== Problem fixed. Keep the issue open for a while, in case someone wants to investigate, thank you !

Not about documentation. I'm following the generated schema https://github.com/EHfive/v2ray-jsonschema and v2ray source code. Note that the above mentioned fields are actually valid fields. However their roles are confusing.

I had the same problem and confirmed that this is a bug with the documentation. I saw entries like this in error.log: 2024/06/03 13:00:34 [Info] features: You are using a deprecated feature: DNS disableCache settings. Please update your config file with latest configuration format, or update your client software. 2024/06/03 13:00:34 [Info] features: You are using a deprecated feature: DNS disableFallback settings. Please update your config file with latest configuration format, or update your client software. 2024/06/03 13:00:34 [Info] features: You are using a deprecated feature: DNS server skipFallback settings. Please update your config file with latest configuration format, or update your client software. It is accompanied by records like: 2024/06/03 13:00:34 [Info] app/dns: DNS: created UDP client initialized for 8.8.8.8:53 2024/06/03 13:00:34 [Debug] app/dns: using default domain matcher 2024/06/03 13:00:39 [Info] features/routing/dns: resolve ip for *****.org > empty response It should be the deprecated settings that have not been marked in the document that caused the DNS function module to malfunction
