Teleport tsh SSH (Identity-First SSH Access, no passwords/static keys)

使用 Teleport tsh CLI 配合显式 Machine ID 身份文件（-i）与代理地址，完成 SSH 登录、远程命令执行、节点列表查询和 tsh scp 文件传输；文档还给出身份文件与代理的解析顺序、身份文件格式校验方法及常见故障排查清单。

Use Teleport tsh CLI with a Machine ID (tbot) identity file to SSH into Teleport-managed hosts or run remote commands through Teleport access controls. Trigger when asked to connect to a Teleport host, execute commands on Teleport nodes, or troubleshoot tsh access using a local tbot-refreshed identity. Complements the teleport-tbot-bootstrap skill for creating and persisting the local Machine ID identity source.

teleport-tsh-ssh

Use this skill to access Teleport SSH nodes via tsh with an explicit identity file (-i) and persistent proxy selection.

Pair this with teleport-tbot-bootstrap to set up and persist the local Machine ID identity source.

Compatibility

Tested against Teleport/tsh/tbot 18.7.0.

Identity policy (required)

Always pass -i <identity-file> to tsh commands.

Default identity path:

  • ~/.openclaw/workspace/tbot/identity

If the default does not exist, discover a workspace identity file and use the best match.

Identity discovery fallback

When default identity is missing, search within workspace for candidate files named like:

  • identity
  • *.identity
  • tbot/identity

Validate candidate format before use. A valid Teleport Machine ID identity file typically contains multiple blocks, such as:

  • -----BEGIN PRIVATE KEY-----
  • an OpenSSH user cert line (*-cert-v01@openssh.com ...)
  • one or more -----BEGIN CERTIFICATE----- blocks

Pick the most likely current file (prefer paths under tbot/, then newest mtime).

Security notes

  • Never commit identity files, bot state directories, tokens, or registration secrets.
  • Prefer explicit paths and least-privilege role mappings for automation identities.

Known limitations (v1.0.0)

  • Focuses on Teleport SSH node access (tsh ssh, tsh ls, tsh scp).
  • Does not cover Teleport app/db/kubernetes access workflows.

Proxy resolution (required)

Resolve proxy in this order:

  1. If TELEPORT_PROXY is set, use it.
  2. Else, read saved proxy from ~/.openclaw/workspace/tbot/proxy (single-line text file) if present.
  3. Else, prompt user for Teleport proxy address, then save it to ~/.openclaw/workspace/tbot/proxy for future runs.

Always include proxy in commands when resolved:

  • tsh -i <identity> --proxy=<proxy> ...

Quick workflow

  1. Confirm tsh is installed.
  2. Resolve identity file path (default first, then fallback discovery).
  3. If no valid identity file is found, prompt user to provide the identity file path.
  4. Resolve proxy (TELEPORT_PROXY first, then saved proxy file, then prompt-and-save).
  5. Check auth status when useful: tsh -i <identity> --proxy=<proxy> status.
  6. Discover hosts if needed: tsh -i <identity> --proxy=<proxy> ls.
  7. Connect/run command with explicit identity:
    • tsh -i <identity> --proxy=<proxy> ssh <host>
    • tsh -i <identity> --proxy=<proxy> ssh <host> -- <command> [args...]
  8. Return concise result + actionable error details.

Command patterns

  • Interactive shell:
    • tsh -i <identity> --proxy=<proxy> ssh <host>
  • Remote command execution:
    • tsh -i <identity> --proxy=<proxy> ssh <host> -- <command> [args...]
  • Set remote login user:
    • tsh -i <identity> --proxy=<proxy> ssh <login>@<host>
    • or tsh -i <identity> --proxy=<proxy> ssh --login=<login> <host>
  • List available nodes:
    • tsh -i <identity> --proxy=<proxy> ls

If user asks what nodes are available, run tsh ls with identity+proxy and report back.

Prefer non-interactive form when user asks for command output.

File copy with Teleport SCP

Use tsh scp with identity+proxy for file transfer. Syntax mirrors OpenSSH scp.

  • Local → remote:
    • tsh -i <identity> --proxy=<proxy> scp <local_path> <host>:<remote_path>
  • Remote → local:
    • tsh -i <identity> --proxy=<proxy> scp <host>:<remote_path> <local_path>

Troubleshooting checklist

  • tsh: command not found → install Teleport client.
  • Identity file missing/unreadable → resolve fallback file; if none found, ask user for path.
  • Missing proxy → ask user for proxy, save to ~/.openclaw/workspace/tbot/proxy, retry.
  • not logged in / cert expired → refresh Machine ID output (tbot service health).
  • access denied → role/login mismatch; verify host and identity origin.
  • host not found → verify with tsh -i <identity> --proxy=<proxy> ls and cluster/proxy context.

Clawhub short description

Use tsh with explicit Machine ID identity (-i) for Teleport SSH, remote commands, node listing, and tsh scp.

Companion skill

Use with teleport-tbot-bootstrap to create and persist the local Machine ID identity source.

Clawhub long description

Standardize Teleport server access with identity-first command patterns. Enforce explicit identity usage, resolve proxy consistently, support host discovery, command execution, and file transfer with practical troubleshooting guidance.
