开启sniffing时，通过dokodemo-door进行UDP re TCP解析时会导致错误

Xray-core版本：1.3.0（V2ray4.34.0及以前版本也复现此问题）

一句话版本：sniffing经过dokodemo-door时，对于部分非标地址会出现解析错误。

使用现象：使用Windows10 Netflix UWP客户端时，播放一段时间后会出现H403错误。

服务端Xray-core会报错类似的日志： common/mux: session 48 ends. > io: read/write on closed pipe app/proxyman/outbound: failed to process outbound traffic > proxy/freedom: connection ends > proxy/freedom: failed to process request > io: read/write on closed pipe app/proxyman/outbound: failed to process outbound traffic > proxy/freedom: connection ends > context canceled

客户端：使用的是LEAN的固件（Xray-core1.3.0），PDNSD解析。在.json中sniffing开启时出现问题，将sniffing关闭时问题解决。可能的原因是对于某些非标地址通过sniffing后地址改变导致解析错误。很久以前的push.apple地址issue可能也是这个问题 issue 前两天彩六老哥的语音问题估计也是这样。issue

H403出现时解析的地址： occ-0-3109-3996.1.nflxso.net

配置文件： "inbound": { "sniffing": { "enabled": true, "destOverride": [ "http", "tls" ] }, "port": 1234, "protocol": "dokodemo-door", "settings": { "network": "tcp,udp", "followRedirect": true } } Xray-core

destOverride 才会出错吧？以及正确的地址应该是？

刚才又经过了一些测试。 Q：destOverride 才会出错吧？ A：确实和destOverride 有关。但是将"destOverride"中的"http","tls"删除后，还会出现问题。（无法将UDP re TCP 通过PDNSD解析？） Q：以及正确的地址应该是？ A：刚才测试了许久，发现这个问题只出现在UDP re TCP这个流程中（NetflixUWP-LEAN的SSRP-PDNSD）。电脑本机Xray-core客户端DNS直接UDP解析 or OPENWRT DoH、UDP解析未出现此问题。还未探测到具体的问题所在，地址解析看log貌似是正确的。其他：MUX开或者关均复现此问题；指纹伪造开或关均复现；测试发现通过dokodemo-door进行UDP re TCP，开启snffing和destOverride的VMess VLESS SS(套TLS)均复现此问题。相关客户端日志：开启MUX： 2021/02/17 12:40:28 [Debug] [1847057587] proxy/dokodemo: processing connection from: 192.168.50.2:8792 2021/02/17 12:40:28 [Info]

刚才看到了这个commit，和此issue有关么？

@cntzjjs 那个 commit 应该和 sniffing 无关，请提供更多信息

是的，昨晚我自编译运行了最新的代码，问题仍复现。这边需要完整的debug日志吗？关于这个问题我先梳理一下SSRP对DNS做解析的步骤，如有错误请帮忙指出。我的理解是：NFUWP应用发起了DNS的UDP请求-PDNSD转换成TCP-dokodemo-door入站-经过流量对于域名进行嗅探后-出站-Xray服务端进行TCP解析后再将结果返回SSRP。

因为这个涉及到的部分有些多，相关pdnsd的调试教程都不好使，未抓到pdnsd包。可能的情况： 1、sniffning-destOverride与PDNSD或者DNS2socks存在兼容问题 2、sniffning-destOverride到的信息不对（目前通过log看解析到的域名信息是正确的） 3、PDNSD或者DNS2socks的TCP_only存在问题。

PS：因个人的能力水平有限，或者个人环境存在不确定性（2台电脑均出现），能看到此issue的朋友也可以查看下，用NF-UWP观看视频，路由器固件LEAN-PDNSD解析，观看一段时间后，或者暂停一段时间后，点击右上角的集数选项，是否会出现H403错误？

建议你给lean建议添加个嗅探开关

PS1：Wireshark抓包中出现了很多rDNS的查询记录PTR，不知道是否和此有关（！！还想问下对于PTR记录Xray-core是怎么处理的？！！）： 2021-2-21 19-25-54 issue 2021-2-21 19-51-46 PTR-PDNSD-Xray造成查询堵塞？

目前针对此问题我的临时解决办法： PDNSD 中配置文件query_method=tcp_only;改为tcp_udp（只要不是纯TCP解析就没事）透明代理json中将sniffning值设置为false也可解决此问题。

passwall关闭嗅探路径： /usr/lib/lua/luci/model/cbi/passwall/api/gen_xray. 搜索 sniffning 字段

pdnsd使用tcp_udp查询路径 /usr/share/passwall/app.sh

Passwall中 DNS凡是为TCP解析的（PDNSD DNS2SOCKS FAKE IP）均复现此问题。以下是完整配置文件： 透明代理json： { "inboundDetour": [ { "port": 1080, "protocol": "socks", "settings": { "udp": true, "auth": "noauth" } } ], "log": { "loglevel": "warning" }, "outbound": { "settings": { "vnext": [ { "port": 443, "users": [ { "id": "uuid", "alterId": 4, "security": "auto" } ], "address": "xxx.xxx.xxx" } ] }, "mux": { "enabled": true, "concurrency": 8 }, "protocol": "vmess", "streamSettings": { "network": "ws", "tlsSettings": { "fingerprint": "chrome" }, "wsSettings": { "path": "/xxxxxxx" }, "security": "tls" } }, "inbound": { "sniffing": { "enabled": true, "destOverride": [ "http", "tls" ] }, "port": 1234, "protocol": "dokodemo-door", "settings": { "network": "tcp,udp", "followRedirect": true } } }

目前针对此问题我的临时解决办法： PDNSD 中配置文件query_method=tcp_only;改为tcp_udp（只要不是纯TCP解析就没事）透明代理json中将sniffning值设置为false也可解决此问题。

我把sniffning 关掉之后基本没法用了啊,youtube无法播放视频,谷歌首页也大概率打不开. 开启后恢复正常

Passwall中 DNS凡是为TCP解析的（PDNSD DNS2SOCKS FAKE IP）均复现此问题。以下是完整配置文件： 透明代理json： { "inboundDetour": [ { "port": 1080, "protocol": "socks", "settings": { "udp": true, "auth": "noauth" } } ], "log": {

PDNSD 中配置文件query_method=tcp_only;改为tcp_udp（只要不是纯TCP解析就没事）透明代理json中将sniffning值设置为false也可解决此问题。

我把sniffning 关掉之后基本没法用了啊,youtube无法播放视频,谷歌首页也大概率打不开. 开启后恢复正常透明代理下如果关了嗅探确实无法工作，socks模式没问题

XTLS / Xray-core

开启sniffing时，通过dokodemo-door进行UDP re TCP解析时会导致错误 #272
