Remote DSH host management for DeepSeek Harness — run a headless dsh instance on your own server and operate it from your local GUI, as if it were a local workspace. Long-running tasks survive your laptop being off.

中文简介:把一台服务器变成你的 DSH「分身」——本地 GUI 左侧边栏混排远程会话、一键打开远程 GUI、SSH 隧道掉线自动重连。长任务甩给服务器,关掉 Mac 也不中断。

  • English documentation: below
  • 中文文档:见文末「中文文档」一节

✨ Features

  • Dual-channel remote control — operate the remote dsh both ways: SSH tunnels + panel (watch its GUI, browse sessions) and dsh CLI control (the sev_run_task agent tool runs one-shot tasks on the remote via ssh + dsh --profile headless).
  • Remote projects — point a task at a server folder (cwd); the remote agent works there and task files land on the server, retrievable via Syncthing / scp.
  • Left-sidebar mixed list — remote sessions appear right next to your local ones (title, running pulse, relative time), Codex-style.
  • One-click remote GUI — open the remote instance's full web UI inside the panel (iframe) or in a tab.
  • Auto-healing SSH tunnels — dropped tunnels reconnect automatically (watchdog), and resume on app restart.
  • Remote session API — session list / health are pulled through the tunnel from the remote host's own API.
  • Recoverable config — host registry is a plain JSON file with an automatic rolling backup (.bak); deletion asks for confirmation.
  • Zero local exposure — remote host only listens on 127.0.0.1; you reach it via an SSH tunnel. Loopback-only API fence.

🏗 Architecture

┌─ your machine (local dsh) ────────────────────────────┐
│  web GUI  ⇄  /api/dsh-sev/*  ⇄  Node half             │
│   · browser half: sidebar entry, mixed session list   │
│   · node half: registry, tunnel lifecycle, watchdog    │
└──────────────┬────────────────────────────────────────┘
               │ ssh -L <local>:127.0.0.1:<remote dsh port> <alias>

┌─ your server (headless dsh, systemd) ─────────────────┐
│  dsh --profile web --host 127.0.0.1 --port 3080        │
│  sessions persist here; long tasks survive laptop off  │
└────────────────────────────────────────────────────────┘

📦 Install

# on the machine running the local DSH GUI
npm i -g pnpm                                   # dsh plugin CLI needs pnpm
dsh plugin --profile web add dsh-sev
# restart the DSH host / web GUI to load the plugin

From source

git clone <this-repo> && cd dsh-sev
npm install && npm run build
dsh plugin --profile web add link:$(pwd)

🖥 Server setup (the "remote host")

Install a headless DSH on the server (Ubuntu 22.04+ example):

# 1. Node + dsh (use a mirror if you are in CN)
npm i -g pnpm
npm i -g @deepseek-ai/dsh --registry=https://registry.npmmirror.com

# 2. Model credentials — the remote instance needs its own API keys:
#    ~/.dsh/settings.yaml          (default model / provider)
#    ~/.dsh/.credentials.yaml      (DeepSeek / provider keys)
#    ~/.modlens/config.json        (vision bridge, if used)
#    export ARK_PLAN_API_KEY=...   (env-based providers, if used)

# 3. systemd unit so it survives reboots (adjust paths)
sudo tee /etc/systemd/system/dsh-web.service >/dev/null <<'EOF'
[Unit]
Description=DSH web (remote host)
After=network-online.target

[Service]
Type=simple
User=<your-user>
Environment=DSH_HOME=/home/<your-user>/.dsh
WorkingDirectory=<dsh-install-dir>
ExecStart=/usr/bin/node <dsh-install-dir>/node_modules/@deepseek-ai/dsh/lib/bin.js --profile web --host 127.0.0.1 --port 3080
Restart=always
RestartSec=3

[Install]
WantedBy=multi-user.target
EOF
sudo systemctl daemon-reload && sudo systemctl enable --now dsh-web

Tip: replicate your local ~/.dsh (settings, credentials, memories, plugin profile) to the server once — the linked plugin sources resolve by relative symlink when kept at the same path. See docs/server-migration.md.

🌐 Networking

The tunnel uses your normal ssh — any reachable address works:

  • Recommended: ZeroTier — a private mesh between your machines, no public ports. Install on both sides, join the same network, and put the server's ZeroTier IP in ~/.ssh/config.
  • Or: LAN IP / VPN / a public IP with keys only.

Example ~/.ssh/config:

Host my-server
    HostName 203.0.113.1          # your server's ZeroTier / LAN IP
    User your-user
    IdentityFile ~/.ssh/id_ed25519
    IdentitiesOnly yes

🚀 Usage

  1. After installing, refresh the GUI. You'll see:
    • a 远程 entry in the left sidebar nav,
    • a 远程会话 group above the workspace list (once a host is online).
  2. Open the 远程 panel, type the SSH alias (e.g. my-server), click 添加.
  3. The plugin auto-starts the tunnel (ssh -L) and shows the host 在线 with its session list.
  4. Click any remote session (or 打开) to operate the remote GUI inside the panel.

Hosts persist in ~/.dsh/remote-hosts.json (with a rolling remote-hosts.json.bak backup).

🔒 Security

  • Remote host binds 127.0.0.1 only — never exposed to the network.
  • All plugin API routes enforce a loopback-only fence (host header + origin checks), mirroring other DSH plugins.
  • Your model API keys live only on machines you control (local + server).
  • The tunnel is just ssh — reuse your existing keys; never commit keys to this repo.

🤖 Agent control (one-shot remote tasks)

After install, the local agent gains a sev_run_task(host, task) tool that runs a task on the remote host through its own headless dsh CLI (ssh + dsh --profile headless). Just ask: "run this on the server: …".

Server-side headless setup (once):

# 1. a dedicated DSH_HOME with the plain DeepSeek provider
mkdir -p ~/.dsh-headless
cat > ~/.dsh-headless/settings.yaml <<'CFG'
llm-deepseek:
  baseURL: https://api.deepseek.com
agent-default-model:
  provider: deepseek-official
  model: deepseek-v4-flash
  reasoningEffort: high
CFG
ln -s ~/.dsh/.credentials.yaml ~/.dsh-headless/.credentials.yaml

# 2. enable the built-in (but disabled) DeepSeek provider for the headless profile
dsh plugin --profile headless add @deepseek-ai/dsh-llm-deepseek
mkdir -p ~/.dsh-headless/profiles/headless
cat > ~/.dsh-headless/profiles/headless/cordis.patch.yml <<'CFG'
- enable:
    - id: llm-deepseek
CFG

Notes: the provider id is deepseek-official; the headless profile ships llm-deepseek disabled by default — the patch above enables it. The tool pipes the task via stdin to a temp file (safe for arbitrary quoting) and times out after 5 minutes.

🛠 Development

npm install        # dev deps: esbuild / typescript / @types/react
npm run build      # bundles lib/client.js (browser half)
npm test           # node --test (11 cases: routes, fence, watchdog, sessions proxy, .bak)
npm run typecheck  # optional tsc --noEmit

Plugin layout:

lib/index.js          # Node half: registry, tunnels, watchdog, /api/dsh-sev routes
src/client/index.tsx  # Browser half: sidebar entry, mixed list, panel, iframe
scripts/build.mjs     # esbuild → lib/client.js (window.__ModuleLoader__.load format)
cordis.patch.yml      # bundle layer manifest (id: sev / name: dsh-sev)

📦 Publishing

npm run build && npm test   # prepublishOnly runs this automatically
npm publish                 # requires an npm account; the package is the "installer"

For the DSH plugin marketplace: install the published package via dsh plugin add dsh-sev; marketplace inclusion follows the DSH plugin registry process.

✨ 功能特性

  • 双通道远程控制 — 两种方式操控远程 dsh:SSH 隧道 + 面板(看远程 GUI、浏览会话)与 dsh CLI 控制sev_run_task agent 工具经 ssh + dsh --profile headless 在远程跑一次性任务)。
  • 远程项目 — 给任务指定服务器文件夹(cwd),远程 agent 就在那里工作,任务文件落在服务器上,可经 Syncthing / scp 取回。
  • 左侧会话混排 — 远程会话直接显示在左侧边栏,跟本地任务并列(标题、运行态呼吸点、相对时间),Codex 同款体验。
  • 一键远程 GUI — 面板内以 iframe 打开远程实例的完整网页界面(也可在标签页打开)。
  • 隧道自动自愈 — SSH 隧道意外断开自动重连(看门狗),App 重启后自动恢复。
  • 远程会话 API — 会话列表 / 健康状态经隧道调用远程实例自身的 API。
  • 配置可恢复 — 主机注册表是纯 JSON 文件,每次保存前自动写滚动备份(.bak);删除前有确认弹窗。
  • 零暴露 — 远程实例只监听 127.0.0.1,本机经 SSH 隧道访问;插件 API 全部 loopback 围栏。

📦 安装

从 npm 安装(推荐)

# 在本机(运行 DSH GUI 的机器)
npm i -g pnpm                                   # dsh 插件 CLI 需要 pnpm
dsh plugin --profile web add dsh-sev
# 重启 DSH host / web GUI 使插件生效

从源码安装

git clone <本仓> && cd dsh-sev
npm install && npm run build
dsh plugin --profile web add link:$(pwd)

🖥 服务器部署(「远程分身」)

在服务器上装 headless DSH(Ubuntu 22.04+ 示例):

# 1. Node + dsh(国内可用镜像加速)
npm i -g pnpm
npm i -g @deepseek-ai/dsh --registry=https://registry.npmmirror.com

# 2. 模型凭据——远程实例需要自己的 API key:
#    ~/.dsh/settings.yaml          (默认模型 / 提供商)
#    ~/.dsh/.credentials.yaml      (DeepSeek / 各厂商 key)
#    ~/.modlens/config.json        (视觉桥,如使用)
#    export ARK_PLAN_API_KEY=...   (基于环境变量的提供商,如使用)

# 3. systemd 守护,重启不丢(按需改路径)
sudo tee /etc/systemd/system/dsh-web.service >/dev/null <<'EOF'
[Unit]
Description=DSH web (remote host)
After=network-online.target

[Service]
Type=simple
User=<你的用户名>
Environment=DSH_HOME=/home/<你的用户名>/.dsh
WorkingDirectory=<dsh 安装目录>
ExecStart=/usr/bin/node <dsh 安装目录>/node_modules/@deepseek-ai/dsh/lib/bin.js --profile web --host 127.0.0.1 --port 3080
Restart=always
RestartSec=3

[Install]
WantedBy=multi-user.target
EOF
sudo systemctl daemon-reload && sudo systemctl enable --now dsh-web

提示:可以把本机 ~/.dsh(settings、credentials、memories、插件 profile)一次性复制到服务器——link 插件按相对路径解析,保持同路径即可。详见 docs/server-migration.md

🌐 组网

隧道用你现有的 ssh,任何可达地址都行:

  • 推荐 ZeroTier — 设备间私有组网,无需公网端口。两端安装、加入同一网络,把服务器的 ZeroTier IP 写进 ~/.ssh/config
  • 或者:局域网 IP / VPN / 仅密钥认证的公网 IP。

~/.ssh/config 示例:

Host my-server
    HostName 203.0.113.1          # 你的服务器 ZeroTier / 局域网 IP
    User your-user
    IdentityFile ~/.ssh/id_ed25519
    IdentitiesOnly yes

🚀 使用

  1. 安装后刷新 GUI,你会看到:
    • 左侧导航栏的 远程 入口,
    • 工作区列表上方的 远程会话 分组(主机在线后出现)。
  2. 打开 远程 面板,输入 SSH 别名(如 my-server),点 添加
  3. 插件自动建立隧道(ssh -L)并显示主机 在线 与会话列表。
  4. 点任意远程会话(或 打开)即可在面板内操作远程 GUI。

主机配置持久化在 ~/.dsh/remote-hosts.json(每次保存自动留 remote-hosts.json.bak 备份)。

🔒 安全

  • 远程实例只监听 127.0.0.1,不暴露到网络。
  • 插件所有 API 路由带 loopback-only 围栏(host 头 + origin 校验),与其它 DSH 插件一致。
  • 模型 API key 只存在于你控制的机器(本机 + 服务器)。
  • 隧道就是 ssh——复用你现有的密钥;永远不要把密钥提交进本仓库

🤖 Agent 控制(一次性远程任务)

安装后,本地 agent 会获得 sev_run_task(host, task) 工具——通过远程主机自己的 headless dsh CLI(ssh + dsh --profile headless)跑任务。直接说「帮我在服务器上跑:…」即可。

服务器端 headless 一次性配置:

# 1. 独立 DSH_HOME + 原生 DeepSeek 提供商
mkdir -p ~/.dsh-headless
cat > ~/.dsh-headless/settings.yaml <<'CFG'
llm-deepseek:
  baseURL: https://api.deepseek.com
agent-default-model:
  provider: deepseek-official
  model: deepseek-v4-flash
  reasoningEffort: high
CFG
ln -s ~/.dsh/.credentials.yaml ~/.dsh-headless/.credentials.yaml

# 2. 启用 headless 内置(默认禁用)的 DeepSeek 提供商
dsh plugin --profile headless add @deepseek-ai/dsh-llm-deepseek
mkdir -p ~/.dsh-headless/profiles/headless
cat > ~/.dsh-headless/profiles/headless/cordis.patch.yml <<'CFG'
- enable:
    - id: llm-deepseek
CFG

注意:provider id 是 deepseek-official;headless profile 默认禁用了 llm-deepseek,上面的 patch 即启用它。任务文本经 stdin 写入临时文件(任意引号都安全),5 分钟超时。

🛠 开发

npm install        # devDeps: esbuild / typescript / @types/react
npm run build      # 打包 lib/client.js(浏览器半)
npm test           # node --test(11 用例:路由/围栏/看门狗/会话代理/.bak)
npm run typecheck  # 可选 tsc --noEmit

插件结构:

lib/index.js          # Node 半:注册表、隧道、看门狗、/api/dsh-sev 路由
src/client/index.tsx  # 浏览器半:侧边栏入口、混排列表、面板、iframe
scripts/build.mjs     # esbuild → lib/client.js(window.__ModuleLoader__.load 格式)
cordis.patch.yml      # bundle 层清单(id: sev / name: dsh-sev)

📦 发布

npm run build && npm test   # prepublishOnly 会自动执行
npm publish                 # 需要 npm 账号;发布的包就是「安装包」
