We establish connections to remote systems without supplying a password, however I do not want to store my password less keys ( passphrase-free keys) on my servers. ssh-agent, takes care of keys with passphase, which allowing me to easily have ssh-agent process per system per login session. How do I dramatically reduces the number of times I’ve to punch my passphrase from once per new login session to once every time my local server is rebooted? How do I use keychain utility for all my backup scripts for secure passwordless login?
