|---|---|
| Linux & macOS | ~/.ssh/config |
| Windows (OpenSSH) | %USERPROFILE%.sshconfig |
| Windows (PuTTY) | %USERPROFILE%Documentssshconfig |
1.4 Syntax and Structure of SSH Config File
The SSH config file follows a specific syntax and structure:
Host alias
HostName hostname
Port port_number
User username
IdentityFile path_to_private_key
custom_settings
1.5 Getting Started with SSH Config for GitHub
Now that we have a basic understanding of SSH config, let’s kickstart our GitHub journey. Here are the essential steps to get you up and running:
- Generate an SSH key pair.
- Add your public SSH key to your GitHub account.
- Edit your SSH config file to configure settings specific to GitHub.
1.6 Configuring Multiple SSH Identities
Using SSH config, you can effortlessly switch between different SSH identities based on the repository or host you are interacting with. This flexibility allows you to manage multiple GitHub accounts or work with various collaborators seamlessly.
1.7 Customizing SSH Behavior with SSH Config
With SSH config, you can unleash a multitude of customization options to tailor your SSH connections to meet your specific needs. From configuring timeouts and connection retries to enabling compression and X11 forwarding, the possibilities are vast.
Chapter 2: Advantages and Disadvantages of SSH Config for GitHub
