DSH Mesh

快速开始

每台机器装一遍
```
dsh plugin add dsh-plugin-mesh
```
desktop profile 要在 DSH 自带终端里跑；其它 profile 用普通终端即可。
重启 DSH

插件在启动时加载，装完必须重启一次。
侧栏点「Mesh」

看到别的机器就是成功了。看不到就看下面的排查。

Install on every machine
```
dsh plugin add dsh-plugin-mesh
```
The desktop profile needs DSH's own terminal; other profiles work from a normal one.
Restart DSH

Plugins load at startup, so restart once.
Click “Mesh” in the sidebar

Seeing another machine means it worked. If not, check troubleshooting.

自己找 —— 每 5 秒向局域网发一个心跳包，同时监听同一个地址。所以不用填 IP。
派活 —— 把任务发给对方，对方自动开一个 agent 会话去做，做完再派回来。
两条路 —— 局域网优先；不在同一网络时，走插件自带的用户态 Tailscale（自动下载，不用装客户端）。需要免费注册 Tailscale 并生成一个授权码，插件里直接给了地址，不用自己找。
会什么 —— 每台机器把自己装的运行时、内存、显卡报上来，派活之前就能看出它做不做得了。

Discovery — every 5 seconds each machine sends a heartbeat to the LAN and listens on the same address. That is why you never type an IP.
Dispatch — a task is sent to the peer, which opens an agent session automatically, does the work, and dispatches the result back.
Two channels — LAN first; across networks it falls back to a bundled userspace Tailscale node, downloaded automatically. No client to install. Needs a free Tailscale account and an auth key — the plugin links to the page that issues it.
Capabilities — each machine reports its runtimes, memory and GPU, so you can tell before dispatching whether it can do the job.

看不到对方 —— 依次确认：① 两台在同一局域网？ ② 对端也装了、也重启了？ ③ 防火墙放行了 TCP 45917 和 UDP 45892？
组播被挡 —— 很多路由器会挡。点面板上的「扫描本网段」主动扫一次即可。
Android 老掉线 —— 是系统省电在杀后台，不是插件的问题。把 DSH 加进电池优化白名单。
安全 —— 默认不校验密钥：同一网络里能连上 45917 的人都能给你派活。在咖啡厅、宿舍这类网络，打开 Mesh 页面「配对码」里的开关，再把两台机器的码对成同一个就行。

No peers — check in order: same LAN? peer also installed and restarted? firewall allows TCP 45917 and UDP 45892?
Multicast blocked — common on many routers. Use the panel's “Scan subnet” button instead.
Android keeps dropping — the OS is killing background apps, not a plugin bug. Add DSH to the battery whitelist.
Security — by default the key is not checked: anyone on the same network who can reach 45917 can send you work. On café or dorm networks, flip the switch in the Mesh panel's “pairing” card and make both machines share one code.
