Using ssh-agent(1) to ease usage of SSH key authentication
Many SSH clients supports “key agent” or “authentication agent”, which holds private key for you, and ease the authentication process.
By default, OpenSSH does not enable this. You can easily use ssh-agent(1) to accomplish the mission.
The above command will start X session with ssh-agent. This means that you can add private key to the agent.
Add your own ssh key.
Then ssh authentications will be accomplished automatically. Note that you may need to use ssh -A in certain configurations.
