I pressed <enter> as empty for both the filename identity and passphrase then sent the public key to A under .ssh and saved as authorized_keys (the first time I sent the key I got message: The authenticity of host 'hostname (host ip)' can't be established) Now if I run scp from B to A, I ALWAYS get password (of the A host) prompted! Which I don't want. ***** Frustrated, I also tried set up running ssh-agent and ssh-add indentity for password authentication but I failed. I am thinking of reset the sshd_config file: RSAAuthentication to yes. Will it help make the problem go away? Thanks so much!
