You can use the ssh-add program to add your passphrase one time to the agent and the agent will in turn pass this authentication information automatically every time you need to use your passphrase. So the next time you run:
you will be logged in automatically without having to enter a passphrase or password.
Once you've verified that ssh-agent is running, you can add your ssh key to it by running the ssh-add command:
If the program finds the DSA key that you created above, it will prompt you for the passphrase. Once you have done so it should tell you that it has added your identity to the ssh-agent:
Identity added: /home/username/.ssh/id_dsa (/home/username/.ssh/id_dsa)
Now you can try logging into that remote machine again and this time you will notice that it just logs you right in without prompting you for any password or passphrase.
