被控端 - 修复 MTU 问题：夹 MSS + 路径 MTU 探测（公网可用率 48% -> 100%） - 复用 HTTP 连接（免掉每次新建 TLS 的 30% 握手失败） - 每分钟回头找局域网，自动切回快 400 倍的路径 - 画面心跳帧：静止时省流量，客户端仍知道流是活的 - 锁屏时给出可操作的提示 手表端 - 内置 GTS Root R4 / GlobalSign Root CA，修 SSLHandshakeException - 连接错误翻译成人话（证书/时间/解析/超时分别提示） - 经中转连上后用服务器报的地址刷新已配对记录 - 新增局域网连接页面、服务器延迟检测 服务器端 - 支持 chunked 请求体（修每 16 秒一次的连接错乱与大面积 502） - 网络调优脚本 net-tune.sh（开机自动应用） - 管理页：批量删除、网络体检、下载区 - 隧道改 HTTP/2 + 双连接 文档 - 许可协议 / 安装前必读 / 安装后须知（作者：小麦子）

# 建具名隧道（固定域名），替换掉会变地址的匿名隧道。
|
||
#
|
||
# 前提：已经 cloudflared tunnel login 授权过（/root/.cloudflared/cert.pem 存在）
|
||
#
|
||
# 做的事：
|
||
# 1. 建一个叫 lanremote 的隧道
|
||
# 2. 把 relay.<域名> 指到它
|
||
# 3. 写隧道配置（指向本机 8080）
|
||
# 4. 改 systemd 服务，改成跑具名隧道
|
||
# 5. 重启并验证
|
||
#
|
||
# 具名隧道的好处（对比匿名）：
|
||
# * 地址固定，不用每次重启都改客户端配置
|
||
# * 不受匿名隧道限流（实测匿名隧道经常 context deadline exceeded）
|
||
# * Cloudflare 官方支持的生产用法
