Generating a new SSH key and adding it to the ssh-agent — by GitHub Docs

beginnerpageLink only (©)

Clear walkthrough for creating an Ed25519 SSH key pair, protecting it with a passphrase and loading it into ssh-agent on Linux, macOS and Windows. It is written for GitHub, but the key generation and agent steps apply to logging in to your own servers with keys instead of passwords.

Quick steps

  1. Generate: ssh-keygen -t ed25519 -C "your_email@example.com" and set a passphrase
  2. Start the agent: eval "$(ssh-agent -s)"
  3. Add the key: ssh-add ~/.ssh/id_ed25519

Tailscale quickstart — by Tailscale

beginnerpage

Shows how to create a private tailnet by installing the Tailscale client on two devices and signing in with the same identity account, then points to follow-ups like MagicDNS, exit nodes, subnet routers and access policies. A VPN-style overlay like this is a safer way to reach home services than opening ports on your router.

Subnet routers — by Tailscale

intermediatepage

Explains how one Tailscale device can advertise a whole LAN so you can reach printers, cameras or a NAS that cannot run the client. You need IP forwarding on the router device, approval of the routes in the admin console, and access rules that permit the traffic. Approving a route does not grant access by itself.
