SSH

Quick SSH agent patterns. Platform-specific pages:

• WSL SSH agent
• PowerShell SSH agent

For reaching machines rather than authenticating to them, see Remote access — Tailscale, Dev Tunnels, T3 Code.

Minimal flow

eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_ed25519
ssh -T [email protected]

Config sketch

~/.ssh/config:

Host github.com
  HostName github.com
