Which of the following commands preloads and manages existing SSH keys that are used for automatic authentication while logging in to order machines using SSH?
man: "ssh-agent is a program to hold private keys used for public key authentication (RSA, DSA). The idea is that ssh-agent is started in the beginning of an X-session or a login session, and all other windows or programs are started as clients to the ssh-agent program. Through use of environment variables the agent can be located and automatically used for authentication when logging in to other machines using ssh"
ssh-agent- commands preloads and manages existing SSH keys that are used for automatic authentication while logging in, it loads the key into memory i.e. if you have passphrase protecting a key instead of keep putting it in every time you try to connect to server, you only put it once and the ssh-agent will remember it for all subsequent logins
The question says preloads and manages. What does preload actually mean ?
ssh -keygen - generates keys but does it manage the keys?, if so whats the purpose of having ssh-agent ? I would naturally choose ssh-agent with this question.
