Frequently asked questions

What does a Host alias give me?

Once a Host block is in ~/.ssh/config, you can run ssh myserver instead of typing the full user, address, port and key every time.

What is IdentitiesOnly for?

It tells SSH to use only the key you specified rather than offering every key in your agent, which avoids failed attempts and 'too many authentication failures' errors.
