ssh-server-ops

What problem does it solve?

SSH failures are rarely as simple as "SSH is broken"—they usually stem from missing local tools, network issues, misconfigured SSH config, or broken authentication chains. This Skill eliminates guesswork by providing a structured, evidence-based workflow to diagnose the exact failure layer and safely repair SSH access from Windows, macOS, or Linux to Linux, POSIX, gateway, bastion, or HPC targets.

Core Features & Use Cases

• Layered Diagnosis: The doctor command produces a structured JSON report covering local tools, TCP reachability, non-interactive public-key auth, transfer capability, and Conda/Paramiko readiness.
• Safe Config & Key Management: Repair or create ~/.ssh/config host blocks and bootstrap password-to-key authentication with passwords confined to local terminal variables.
• Remote Execution & Transfer Fallback: Run standardized remote commands through OpenSSH or fall back to Paramiko SFTP for file transfers, with first-class support for Slurm/HPC login nodes and bastion hosts.

Quick Start

Use the ssh-server-ops skill to run a read-only diagnosis on your target host and report the likely root cause along with the recommended next safe action.
