加 EzHub SSH 密钥诊断脚本

诊断结论：EzHub 的 SSH 服务是**系统 OpenSSH 9.6**（banner 看出来的），不是 Gitea/Forgejo 内置的 SSH 服务。密钥在 EzHub 上注册的指纹和本机完全一致（SHA256:Acmu49YQcjw3m5WefOXSBzYNY2WPHLL2vvhnlYRAttA），但服务端一直返回 Permission denied (publickey,password)。说明 git 用户的 authorized_keys 没有跟 Gitea 数据库同步 —— 这是服务端配置问题，客户端怎么试都过不去。服务端要做的（任选其一）： a) 开启内置 SSH：app.ini 里 START_SSH_SERVER = true 并放行端口 b) 继续用系统 OpenSSH，但给 sshd 加 AuthorizedKeysCommand 指向 gitea/forgejo 的 keys 子命令 PS：这个实例的 UI 主题是 forgejo-auto，实际是 Forgejo。
发布脚本：EzHub 走 HTTPS+令牌推送（SSH 还没配好）

+## 1.8.0
+
+**这一版主要是「修看不见的稳定性问题」。**
+
+- 修**跨网络老断**（Error 1033 / 502 / 530 的真因）：
+  4G 链路会**静默断开 TCP 连接**（不发 FIN/RST，双方都以为还活着），
+  Cloudflare 把请求发到这种"僵尸连接"上就报错。
+  而 Linux 默认要 **2 小时**才发现连接死了 —— 中间这段时间
+  服务一直"看着在线、实际打不开"。
+  现在改成 30 秒探测、60 秒内发现并重连
+
+- 修**跨网络抖动**：隧道连接数从 2 提到 4。
+  只剩 1 条连接时跨机房回源会失败，实测可用率 0/12；
+  提到 4 条后稳定 12/12
+
+- 修**掉电重启后恢复太慢**：原来开机要 **2 分 10 秒**公网才恢复，
+  那段时间浏览器看到的就是 Error 1033。
+  根因是系统里 NetworkManager 和 systemd-networkd 同时在跑，
+  后者等一个不归它管的网络，干等 2 分钟超时失败，
+  把启动流程一起拖住了。改完 **17 秒**就绪，掉电重启后 24 秒公网可用
+
+- 修**看门狗自己制造不稳定**：它每隔 50 秒重启一次隧道，
+  但隧道重建 4 条连接要 30~60 秒 —— 每次还没建齐就被下一次打断，
+  永远停在"只剩 1 条"的状态。现在重启后有宽限期，
+  并且会区分"没建好过"和"建好过又垮"，后者立刻重启
+
+- **官网重新设计**：层次更清楚，白色简洁风格
+
+- **官网新增产品展示**：手表界面预览（颜色和布局与真实手表一致）、
+  电脑端真实截图、两种连接方式对比图
+
+- 清理**僵尸设备记录**：设备列表原来只增不减，
+  实测一天攒了 75 条无效记录，拖慢手表和网页访问。
+  现在超过 6 小时没上报的自动清掉，占用的配对码一起释放
+
+- 修下载文件用 `HEAD` 探测时长度报 0（部分下载器会误判成空文件）
+
+- 支持 `HEAD` 请求（原来一律返回 501）
+
+## 1.7.1
+
+- 修**卸载卡死**：从控制面板卸载时进度条永远走不完。
+  根因是被控端在无控制台的隐藏进程里调 `AllocConsole` 和
+  读控制台输入，会永久阻塞
+- 修**安装回滚**：旧版本程序还在后台跑时，安装器关不掉它，
+  弹「无法关闭所有应用程序」，静默安装会整个回滚 ——
+  用户看到的是"装了没反应"
+- 修卸载残留：开机自启注册表项没删掉、安装目录留个空壳
+- 修手表连上后**一片白屏**：分页初始化函数从没被调用过，
+  标签栏里只剩一个孤立的指示器
+- 修「被控端已关闭新设备配对」把重装手表的人永久挡在外面：
+  配对码本身就是钥匙，拿着正确的码就该放行
+- 手表端应用名改成 ykxmz
+- 修跨网络**延迟高**：隧道退回了 QUIC（`--protocol http2` 参数丢失），
+  可用率只有 48%；恢复 HTTP/2 后可用率 100%
+- 网络调优持久化：TCP 缓冲 4 MB、FastOpen、
+  空闲后不重置拥塞窗口（长轮询场景关键）
+- 手表提示改成自诊断式：连不上时直接打出双方地址，
+  一眼看出是网段不同还是连错了 WiFi
+- **官网重新设计**：导航 / 功能 / 三步上手 / 下载 / 常见问题
+- 官网改成白色简洁风格
+
+## 1.7.0
+
+- 电脑端改成 **Windows 安装包**（Inno Setup），双击安装，不再需要解压 zip
+- 安装向导里填 6 位配对码，装完手表直接连，不用再跑一次设置
+- 安装包支持静默批量部署：`ykxmz-setup-1.7.0.exe /VERYSILENT /CODE=123456`
+- 三份说明文档合并进安装向导，必须接受才能继续
+- 修配置分裂问题：管理员装的配对码，普通用户账号看不到（数据目录改成按安装位置判断）

+
+## 一、修「跨网络老断」的真因（Error 1033 / 502 / 530）
+
+这一版最主要的东西。现象是：手机/手表打开中转地址，时不时看到
+Cloudflare 的 Error 1033 或者 502、530，过一会又自己好了。
+
+**根因是 4G 链路会静默断开 TCP 连接** —— 不发 FIN 也不发 RST，
+双方都以为连接还活着。Cloudflare 把请求发到这种「僵尸连接」上就报错。
+
+而 Linux 默认要 **2 小时**才发现连接已经死了，中间这段时间
+服务一直处于「看着在线、实际打不开」的状态。
+
+**改了什么**
+- 把 TCP 存活探测改成 30 秒一次、连续 3 次没回应就断开重连
+  → 最多 60 秒发现僵尸连接
+- 隧道连接数从 2 条提到 4 条。实测只剩 1 条连接时，
+  跨机房回源会失败（可用率 0/12），4 条时稳定 12/12
+
+## 二、修「掉电重启后要等两分钟」
+
+原来设备重启后，要 **2 分 10 秒**公网才能访问，那段时间
+浏览器看到的就是 Error 1033。
+
+原因是系统里有两个网络管理服务同时在跑，其中一个在等
+一个不归它管的网络，干等 2 分钟超时失败，把整个启动流程拖住了。
+
+**改完：开机 17 秒就绪，掉电重启后 24 秒公网可用。**
+
+## 三、看门狗重做
+
+看门狗负责在隧道不通时自动重启它。这一版修了它自己的两个问题：
+
+- 之前它每 50 秒重启一次隧道，但隧道重建连接要 30~60 秒，
+  **每次还没建好就被下一次重启打断**，反而永远恢复不了
+- 加了宽限期；又发现宽限期太长会在链路持续不好时干等
+- 最终逻辑：**建好过又断 = 真故障，立刻重启；一直没建好 = 它在努力，继续等**
+
+## 四、官网重新设计
+
+导航结构更清楚，整体白色简洁风格。
+
+新增产品展示区：
+- **手表界面预览**（颜色和布局与真实手表一致）
+- **电脑端真实截图**
+- **两种连接方式对比图**（局域网直连 vs 跨网络中转）
+
+## 五、清理僵尸设备记录
+
+设备列表原来只增不减，实测一天攒了 **75 条**无效记录，
+拖慢手表和网页访问，配对码占用数也虚高。
+
+现在超过 6 小时没上报的设备自动清掉，它占用的配对码一起释放。
+
+## 六、其它
+
+- 修下载文件用 `HEAD` 探测时长度报 0（部分下载器会误判成空文件）
+- 支持 `HEAD` 请求（原来一律返回 501）
+

+
+## 验收结果
+
+| 项目 | 结果 |
+|---|---|
+| 全量回归 | **33 个阶段全部通过** |
+| 安装包完整周期 | **20/20**（静默安装 7 秒、卸载 0.6 秒、无残留） |
+| 网页响应头 | **12/12** |
+| 公网可用率 | 26/30 = 86%（底层 4G 丢包 30%，这是链路的上限） |
+
+> 说明：可用率受限于现场 4G 网络质量。换有线网络或把中转
+> 放到有公网 IP 的服务器上可以显著改善。

+
+排查过程（一步步排除，记录下来免得以后重踩）：
+
+  1. 现象：从控制面板卸载，进度条永远走不完。
+  2. 先怀疑 input()：安装器用 runhidden 调 --uninstall，没有 stdin，
+     input() 会一直等。加了 isatty 保护 —— **没解决**。
+  3. 再怀疑 Popen 没重定向 stdio：_schedule_self_delete 起的 cmd
+     继承了父进程句柄，capture_output 会等管道 EOF。加了
+     DEVNULL 重定向 —— **还是卡**。
+  4. 又发现 _kill_running 用 taskkill /IM ykxmz.exe 把正在卸载的
+     自己杀了（--uninstall 就跑在 ykxmz.exe 里），
+     导致后面的"删自启/删数据"没执行。改成 /FI "PID ne self" ——
+     自启能删了，**卸载仍然卡**。
+  5. 最后看进程状态才定位：卡住的 ykxmz.exe 只有 **1 个线程、
+     0.16 秒 CPU、19MB 内存** —— 明显停在启动早期，根本没干活。
+     那就是 cli_uninstall 第一行的 attach_console()：
+     它对 --windowed 程序调 AllocConsole()，再 open("CONIN$")。
+     在没有控制台的隐藏进程里，这一步**永久阻塞**。
+
+修法：加 --quiet。安装包的卸载器用
+      ykxmz.exe --uninstall --keep-dir --quiet
+      --quiet 下完全不碰控制台（不 AllocConsole、不 input），
+      结果写进 uninstall.log 供排查。
+      实测：不带 --quiet 无限卡住；带了 **0.6 秒返回**。
+
+顺带修的两处（也是实测发现的）：
+  * 安装器关不掉以管理员身份运行的旧实例 -> Inno 弹"无法关闭所有
+    应用程序"，静默下被压成"终止"，**整个安装回滚**。
+    改成 PrepareToInstall 里自己 taskkill /F。
+  * 测试脚本把注册表路径写成 HKCU\\...（少了冒号），
+    PowerShell 静默返回空，"开机自启"永远误报失败。
+
+最终实测（test_installer_cycle.py，20 项）：
+    静默安装   退出码 0，7.1 秒
+    配对码     正确写入 C:\\ProgramData\\ykxmz\\data\\settings.json
+    进程/端口  在跑，8765 监听
+    开机自启   已设置

+COMMIT_MSG = """修四个安装/卸载卡死的 bug（都实测复现过）
+
+1. 卸载里 input() 在无 stdin 时永久阻塞
+   从控制面板卸载**永远卡住不结束**。安装包的 [UninstallRun]
+   用 runhidden 调用，没有 stdin，input() 就一直等。
+   改成只在 sys.stdin.isatty() 时才等回车。
+
+2. Popen 没重定向子进程 stdio，导致 capture_output 等管道 EOF
+   _schedule_self_delete 起的 cmd 继承了父进程的 stdout/stderr 句柄，
+   任何用 capture_output 调 --uninstall 的地方都会一直等，
+   表现为"程序卡死"（实测 90 秒不返回，改后 0.2 秒）。
+   Popen 加 stdin/stdout/stderr=DEVNULL。
+   顺带把延迟从 timeout 换成 ping —— timeout 在 DETACHED_PROCESS
+   下没有控制台会立刻失败，等于没延迟直接删。
+
+3. _kill_running 用 taskkill /IM ykxmz.exe 把**自己**杀了
+   --uninstall 本身就跑在 ykxmz.exe 里，这条命令一发，
+   后面的"删开机自启""删数据目录"全都没执行。
+   现象：卸载看着完成了，HKCU 的自启注册表项还留着。
+   改成 /FI "PID ne <self>" 排除自己。
+
+4. 安装器关不掉以管理员身份运行的旧实例 -> 整个安装回滚
+   Inno 自带机制只会"请求"对方退出，遇上常驻的服务进程关不掉，
+   弹"无法自动关闭所有应用程序"，静默模式下被压成"终止"，
+   安装直接回滚 —— 用户看到的是"装了没反应/还是旧版本"。
+   改成 PrepareToInstall 里自己 taskkill /F，关掉 Inno 那套。
+
+另外修了两个卸载残留：
+   * 安装目录留个空壳 -> [UninstallDelete] 加 dirifempty
+   * ProgramData\\ykxmz 没删 -> 加进 [UninstallDelete]
+
+还有一处 Inno 写法陷阱（踩了三次）：
+   注释里写 [区段名] 或 {常量} 会让编译直接失败，
+   因为 [Code] 解析器连注释内容也处理。
+   加了 _build/check_iss.py 专门扫这个，并进全量套件。
+
+实测结果：
+   静默安装  5 秒内退出，退出码 0，配对码正确写入，程序自动跑起来
+   静默卸载  0.7 秒退出（原来无限卡住）
+   全量回归  29 项全通过
+   卸载逻辑  11 项全通过

-
-**不能全局替换** —— 项目里有 40 多个文件含 "1.4.0"，其中大部分是：
-    * 测试用的数据（配对码、设备版本号字段）
-    * HTTP User-Agent "LanRemote/1.4.0"
-      （Cloudflare 的 Browser Integrity Check 认这个，
-        而且 20 多个测试都在断言它 —— 动它要同步改一大片）
-    * _build/ 下的一次性脚本（历史记录，不用改）
-
-所以只改**用户能看到版本号的地方**：
-    1. android/build_apk.ps1   APK 文件名 + manifest 版本
-    2. docs/*.txt              三份文档
-    3. windows/lanremote/__init__.py   __version__
-    4. 会断言版本号的测试

+r'''检查 Inno Setup 的 .iss 里有没有会害编译失败的写法。
+
+踩过的三个坑，都是 Inno 的 [Code] 解析器**连注释内容也处理**：
+
+  1. 注释里写方括号区段名
+         { 规范化，后面 [Run] 阶段用得到 }
+     报 "无效的区段标记"，编译直接失败。踩了两次。
+
+  2. 注释里写花括号常量
+         { 不带 --keep-dir 的话会 rmdir 删 {app} }
+     Inno 会把 {app} 展开，展开后花括号配不上 ->
+     报 "Syntax error"，编译失败。踩了一次。
+
+  3. 注释里写 {param:XXX|}
+     Inno 会展开它，参数没传就展开成空，同样破坏括号配对。
+
+所以规则：**[Code] 段落里，注释内容不能出现 [Section] 或 {常量}。**
+
+⚠ 判断"是不是注释"必须跳过字符串字面量：
+     ExpandConstant('{app}\x')    <- 这里的 { 在字符串里，不是注释
+     { 这是注释 }                  <- 这里的 { 才是注释

+        公网不通（HTTP 000，ha_connections=2）  <- 隧道显示连着，公网不通

+      也就是说：**间歇性假活**，短样本测不出来。
+      我之前只测 15~25 次就说"可用率 100%"，太草率了。
+
+根因：4G 链路会**静默断开** TCP 连接 —— 不发 FIN/RST，双方都以为还连着。
+      Cloudflare 把请求发到这条僵尸连接上，就回 502/530/1033。
+      Linux 默认 tcp_keepalive_time = **7200 秒（2 小时）**才发现连接死了，
+      所以中间这段时间服务一直"看着在线、实际打不开"。

+        Lost connection           22 次
+
+修法：
+  1. TCP keepalive 调到 30 秒 + 每 10 秒探测 3 次
+     => 最多约 60 秒发现僵尸连接，cloudflared 立刻重连
+     （/etc/sysctl.d/97-ykxmz-keepalive.conf）
+  2. 隧道连接数 2 -> 4，多几条冗余
+  3. 修 relay 从不清理设备记录的问题：
+     self.devices 只增不减，被控端每换端口/重装就多一条，
+     实测一天攒了 75 条僵尸记录，/v1/health 从几 KB 涨到 20KB。
+     加 DEVICE_TTL（6 小时）在 snapshot() 里清掉。
+
+实测（修完立刻验证）：

+
+用户反馈两件事：
+  1. 早上打开 relay.xxmxxs.top 看到 Cloudflare Error 1033 —— "这就是你说的优化好了？"
+  2. "中转管理那边 ui 界面大改，现在难看的要死"
+
+============ 一、隧道 1033/502/530 的真因 ============
+
+之前我只测 15~25 次就说"可用率 100%"，太草率 ——
+实际是**间歇性假活**：隧道显示 ha_connections=2 连着，
+公网却 502/530/000。watchdog 日志把过程记了下来。
+
+根因：**4G 链路静默断开 TCP 连接**（不发 FIN/RST，双方都以为还活着）。
+Cloudflare 把请求发到这条僵尸连接上就回错误。
+Linux 默认 tcp_keepalive_time = **7200 秒（2 小时）**才发现，
+中间这段时间服务一直"看着在线、实际打不开"。
+
+修法（都有实测数据支撑）：
+  1. tcp_keepalive 30 秒 + 每 10 秒探测 3 次
+     => 最多约 60 秒发现僵尸连接并重连
+  2. 隧道连接数 2 -> 4
+     （对照实验：http2+2 只有 1 条连上时公网 0/12；
+       http2+4 稳定 12/12。连接数太少会出现"只有 1 条"的危险窗口）
+  3. 协议定为 http2（cloudflared 自检说 TCP 7844 被墙，
+     但实测 http2 反而比 quic 稳）
+
+实测：http2+4 之后公网 40/40 = 100%，最慢 1.3 秒，0 次重连。
+
+============ 二、中转管理后台重做 ============
+
+原来是几百行内联在 relay.py 的 f-string 里（HTML+CSS+JS 全挤一起），
+改一处样式要在一堆转义花括号里翻。拆成独立模块 relay/admin.py。
+
+新版设计（对齐官网那套白色简洁）：
+  * 吸顶顶栏：品牌 + 运行状态 + 版本/内存/请求数
+  * 公网地址给最大权重（这是用户最需要复制的东西）
+  * 四个数字卡（在线/会话数带颜色区分）
+  * 设备表卡片：状态圆点、等宽配对码、行悬停
+  * 工具卡：网络体检 + 下载区并排
+  * 空状态改成图标+引导文案，不再是干巴巴一句
+  * 窄屏时表格自动变卡片
+
+relay.py 从 2089 行缩到 1550 行。
+
+============ 三、顺手修的两个真 bug ============
+
+1. 设备记录只增不减
+   self.devices 从不清理，被控端每次换端口/重装就多一条，
+   实测一天攒了 75 条僵尸记录，/v1/health 从几 KB 涨到 20KB。
+   加 DEVICE_TTL（6 小时）在 snapshot() 里清。
+
+2. 配对码映射也没清
+   RELAY.codes 和 devices 是一对孪生 dict，
+   只清 devices 会留下指向已删设备的孤儿条目 ——
+   管理页显示"配对码占用 131"，实际一台设备都没有。
+   现在一起清。
+
+============ 四、我自己造的两次事故（如实记录） ============
+
+1. 删文件删过头
+   用"从 _admin_page 截到文件末尾"的方式替换方法，
+   但 _admin_page 后面**还有 _esc/_kb/_uptime/class Server/main()**。
+   结果 relay 起不来，systemd 重启 24 次，所有接口 000。
+   教训：**"删到文件末尾"之前必须先确认末尾有什么。**
+
+2. ADMIN_PATH 引用了不存在的常量
+   路由里写的是字面量，我却在新代码里用了 ADMIN_PATH，
+   管理页一访问就 NameError。现在统一定义了常量。
+
+二者都是"改完没立刻验"造成的。现在每次改完都跑一遍
+管理页 + 官网 + 关键接口的回归。

+查 watchdog 日志，发现它在**每 50 秒重启一次隧道**：
+    [10:31:57] 只剩 1 条连接 -> 重启隧道
+    [10:32:22] 重启完

+    [10:32:47] 距上次 50 秒 -> 又重启

+
+根因（我上一版的错）：
+  隧道在**质量差的 4G 上重建 4 条连接要 30~60 秒**。
+  而我上一版把 MIN_RESTART_GAP 设成 45 秒，并且

+现象（手表日志）：
+    已更新电脑地址为 192.168.2.64:8765
+    电脑不在同一网络，继续用中转
+
+判断逻辑在手表端 MainActivity：
+    pickSameSubnet(client.relayLanIps())   <- 拿电脑报上来的 lanIps
+      localIpv4List()                      <- 拿手表自己的网卡 IP
+      sameSubnet(a, b)                     <- 比前 3 段（/24）
+
+可能出问题的地方：
+    1. 被控端报的 lanIps 里全是虚拟网卡（VMware/VirtualBox/Hyper-V）
+       —— 真实的 192.168.2.64 反而不在里面
+    2. 手表自己的 localIpv4List() 拿到的是运营商 IP（移动数据）
+    3. 手表和电脑真的不在一个网段
+
+这个脚本查第 1 条：本机被控端实际会报哪些 IP。
+第 2、3 条要手表端日志，我先把能查的查清。

+r'''带重试的增量推送 —— 把 44 个提交逐个推到 EzHub。
+
+为什么逐个推：
+    一次性推 44 个提交 = 117 MB，EzHub 的 nginx 返回 413。
+    但 Git 推送是"增量"的：第一个提交推成功后，
+    后面每个提交只需要传自己新增的对象。
+    逐个推，每包只有几十 KB ~ 几 MB，就不会撞上限。
+
+为什么带重试：
+    这台网络（4G + 家宽）会偶发连不上 git.261826.xyz。
+    实测推第 5 个提交时报 "Failed to connect" —— 纯网络抖动，
+    重试就好。不加重试会白费前面推成功的部分（虽然它们已经进仓库了，
+    但脚本会误以为整体失败）。
+
+已经推上去的提交会自动跳过（push 会说 Everything up-to-date）。

+# 原理：
+#   cloudflared 建隧道时会连 region1.v2.argotunnel.com / region2.v2.argotunnel.com，
+#   这两个域名由 Cloudflare 的 GeoDNS 解析 —— 国内 4G 常常被解析到美西（lax），
+#   单程 200ms+，加上丢包重传，实际往返能到 4 秒。
+#
+#   但 Cloudflare 在全球有大量 anycast 边缘 IP，其中不少在亚太（香港/新加坡/
+#   东京/首尔）能直连，延迟低得多。做法是：
+#       1. 测一批候选 IP 的 TCP 7844（隧道端口）握手延迟
+#       2. 挑最快的写进 /etc/hosts，覆盖 GeoDNS 的结果
+#       3. 重启隧道，实测隧道往返
