Windows Hosts

PowerShell 执行

Start-Process -FilePath notepad.exe -Verb runas -ArgumentList \"$env:SystemRoot\\system32\\drivers\\etc\\hosts\"\n

在 Hosts 文件后加入并保存

172.67.200.115 xjtu.app\n

Linux Hosts

Bash 执行

sudo nano /etc/hosts\n

在 Hosts 文件后加入并保存

172.67.200.115 xjtu.app\n

MacOS Hosts

应该和 Linux 差不多？但是我没用过搞不清楚

Xray

如果使用 Xray 内置 DNS 服务器，可以配置解析
\n注意 outbound 需要配置 targetStrategy 确保请求地址是 IP 而不是 FQDN
\n如果 Xray 不是系统 DNS，inbound 需要配置 sniffing.destOverride

{\n    \"dns\": {\n        \"hosts\": {\n            \"domain:xjtu.app\": \"172.67.200.115\"\n        }\n    },\n    \"inbounds\": [\n        {\n            \"sniffing\": {\n                \"enabled\": true,\n                \"destOverride\": [\n                    \"http\",\n                    \"tls\",\n                    \"quic\"\n                ]\n            }\n        }\n    ],\n    \"outbounds\": [\n        {\n            \"targetStrategy\": \"UseIP\"\n        }\n    ]\n}\n

伟大的门友 @komeiji_koishi 无私地接收了你站。

为什么会访问不了&报Cloudflare1000DNS指向错误IP？

域名迁移到了新的账户
\n这个报错指的是是把老的DNS解析迁过来了？指向了CF内部的网络。
\n本应该指向迁移后的服务器的IP

配置应该大概率没有错（或许可以再检查一下，关掉橙云），我起初怀疑是DNS缓存的问题，不过时间长了还有说明应该不是这个原因。

那我也不知道是什么原因了。

100%避免此错误的方法：

cat /etc/hosts\n142.171.227.158 xjtu.app\n

有时有效的方法：
\ncat /etc/resolv.conf
\nnameserver 1.1.1.1
\nnameserver 8.8.8.8

无法使用邮箱注册

没关系，可以用Discourse ID注册。

建议有空的时候，可以换一台性能好点的服务器，作为参考：迁移前的原服务器GB5单核1000，总共4核。大致是Hetzner CPX31的水平。
