Right now I use passwords for some ssh connections, and passwordless ssh for crontab rsyncs, using passwordless rsa keys. (When it asked to enter a password for ssh-keygen I just hit enter). Does this leave me vulnerable? Is there a how-to on this that explains how to use ssh-agent with keys with passes?
I recommend Keychain http://www.gentoo.org/proj/en/keychain/. With keychain, you can log in and unlock your keys and allow your ssh communications to use them as needed. You do have to unlock them after each reboot.
