If you invoke a command under ssh-agent, that comamnd (and all its children) inherit ssh-agent's environment, which includes the SSH_AUTH_SOCK variable, pointing to the authentication socket. Only that user (or root, and you trust root, right) can access this socket. For convenience (and some risk), you can also enable agent-forwarding (I prefer doing this to a limted set of hosts or domains). This would enable you to say: ssh from localhost to adminbox.datacenter.example.com ssh from adminbox.datacenter.example.com to other hosts within the DC. Very handy if you need to run quick commands, git pulls/pushes, scp, rsync, etc., within the DC, without having to constantly re-type your password. Of course, the more often you type your password, the more memorable it becomes. > > # ssh-keygen -t rsa ( passphrase should be empty ) > > Yes I did exactly that but following advice from this mailing list have > changed to DSA and imposed a passphrase. Either works. RSA takes merits. Password SHOULD be provided. -- Dr. Ed Morbius Chief Scientist Krell Power Systems Unlimited
