README

dsh-secure-remote

独立的 DeepSeek Harness SSH 安全与稳定性插件。它通过 bundle patch 替换内置 ssh provider,不修改 DeepSeek Harness 上游源码,也不迁移现有 ssh_workspace v1 数据。

English README

1.1.2 能力

  • macOS / Linux 使用短路径私有目录运行 OpenSSH ControlMaster,修复 macOS ControlPath too long 导致的 PTY 启动失败。
  • Windows 本地端使用系统 ssh.exe,明确关闭 ControlMaster;状态探测和应用层重连仍可用。
  • Key 模式自动发现 SSH Config 主机和默认密钥;支持选择单个密钥文件或文件夹。
  • Password 模式只显示 Host / Port / User / Password;密码通过 DSH credentials 服务保存,不进入 SSH 参数、日志或状态接口。
  • Workspace 行显示 connected、connecting、degraded、disconnected 状态点、延迟和脱敏原因。
  • 保留官方 openRawChannel 原始 SSH 通道,兼容 Remote Agent 安装和长连接。
  • 官方 @deepseek-ai/dsh-ssh 未发布或不可解析时,自动使用随插件发布的兼容 runtime;该 peer 依赖为可选项。
  • 远程文件工具严格限制在 Workspace 根目录,拒绝 ..、前缀碰撞和符号链接逃逸。
  • 远端必须是 POSIX 系统;检测到 Windows 等非 POSIX 目标时返回 REMOTE_OS_UNSUPPORTED。
  • 保留已有 SshProfile、RemoteWorkspaceView、Workspace RPC、Session、Bash 和 Terminal 兼容性。

安全边界

文件工具受到 Workspace 根目录保护;远程 Bash 保持原有行为,拥有远程 SSH 账号本身的完整权限,不宣称受到文件边界隔离。默认保持 StrictHostKeyChecking=yes,不会自动降级到 no/off。

支持矩阵

本地端SSH 客户端ControlMaster状态/重连远端目标
macOS系统 OpenSSH启用支持POSIX
Linux系统 OpenSSH启用支持POSIX
Windowsssh.exe禁用支持POSIX

要求 Node.js 22+,以及兼容的 DeepSeek Harness Web profile。Windows 本地端已实现代码分支,但真实 Windows SSH fixture 需要在 Windows CI 或 Windows 机器上执行。

安装

发布到 GitHub 后,安装指定版本:

dsh plugin --profile web add github:startGalway/dsh-secure-remote#v1.1.2

本地开发安装:

dsh plugin --profile web add file:/absolute/path/to/dsh-secure-remote

安装后重启 Web profile。卸载插件不会迁移或删除已有远程 Workspace:

dsh plugin --profile web remove dsh-secure-remote

配置默认值

workspaceBoundary: deny
connectionReuse: true
controlPersistMs: 300000
serverAliveIntervalSec: 15
serverAliveCountMax: 3
statusProbeIntervalMs: 30000
maxTransferBytes: 8388608

本地开发

npm run check
npm test
npm run pack:check

已知限制

  • Bash 不受 Workspace 文件边界限制。
  • 远程 Windows 本轮不支持。
  • 当前版本不包含双向目录镜像、原子文件传输、后台任务和远程 Git 工作流。
  • Unix 侧保留一个 0700、短路径的兼容启动器,因为当前 DSH SSH runtime 只暴露单一 sshPath 接口;Windows 直接调用系统 ssh.exe。
