How to Use SSH Config Generator

  1. 1

    Add SSH hosts

    Click 'Add Host' and enter a hostname alias, IP address, username, and port. The generator creates individual Host blocks.

  2. 2

    Configure authentication

    Specify identity file paths, key types (RSA, ED25519), and backup authentication methods (password, agent).

  3. 3

    Setup jump hosts

    For machines behind a bastion, add a ProxyJump field pointing to the intermediate host. The tool auto-chains configurations.

  4. 4

    Enable port forwarding

    Add LocalForward (expose remote port locally) or RemoteForward (expose local port on remote). Set up SOCKS proxies for tunneling.

  5. 5

    Export and deploy

    Copy the config to ~/.ssh/config. The generator validates syntax and shows connection command examples for testing.

Frequently Asked Questions

Where does the SSH config file go?
Save as ~/.ssh/config on macOS/Linux or C:\Users\{name}\.ssh\config on Windows. SSH reads this file automatically when you connect.
What is ProxyJump?
ProxyJump lets you connect through an intermediate server (bastion/jump host) automatically. Instead of SSH-ing to the bastion first, SSH chains the connections transparently.
Can I set up port forwarding?
Yes, configure Local (-L for accessing remote services locally), Remote (-R for exposing local services remotely), and Dynamic (-D for SOCKS proxy) port forwarding.
Can I import my existing SSH config?
Yes, paste your current ~/.ssh/config content to populate the form. Edit entries visually and regenerate the configuration.
Is this tool secure?
Your SSH config is generated entirely in your browser. No data is sent to any server. Important: never paste private keys into any online tool — this tool only handles config files.
