SSH Server Administration

A comprehensive skill for secure remote server management via SSH. Supports command execution, file transfers, port forwarding, and tunneling. Cross-platform compatible: Windows, macOS, and Linux.

Platform Detection

CRITICAL: Detect the operating system first to use the correct SSH approach.

Before executing SSH commands, check the platform:

• Windows: Use PowerShell or Windows OpenSSH (built into Windows 10+)
• macOS/Linux: Use standard bash SSH commands

Authentication Methods (In Order of Preference)

1. SSH Key Authentication (RECOMMENDED - Works Everywhere)

SSH keys are the most secure and reliable method. They work identically on all platforms.

Check for existing keys:

# Windows (PowerShell)
Get-ChildItem ~/.ssh/id_*.pub

# macOS/Linux
ls -la ~/.ssh/id_*.pub

If keys exist, use them:

# All platforms - key auth is automatic if keys are set up
ssh -o StrictHostKeyChecking=accept-new [username]@[host] "[command]"

If no keys exist, help user create them:

# All platforms (works in PowerShell, bash, zsh)
ssh-keygen -t ed25519 -C 


ssh-copy-id -i ~/.ssh/id_ed25519.pub [username]@[host]


 ~/.ssh/id_ed25519.pub | ssh [username]@[host]
