SSH - Secure Shell

SSH

If you have ssh-agent running in one shell, when you open up another shell, you do not have ssh-agent running in the new shell. You will have to run the command for each shell you are planning to use with SSH if you want to use ssh-agent.
You can see what keys are being used by ssh-agent with the following command:

            [mlevan@Hamming ~]$ ssh-add -l
            1024 c3:53:83:99:80:d8:ef:97:2d:bb:1d:14:39:b2:a9:8f /home/mlevan/.ssh/id_rsa (RSA)
            [mlevan@Hamming ~]$

You need to be in the ssh-agent shell in order to use this command. This will not work if you are logged into your remote system.
