This is my first time installing ssh and I am getting the following error: $ ssh <hostname> The authenticity of host <hostname> can't be established. RSA key fingerprint is <xxxxxxxxxxxxxxxxxxxxxxxxx>. Are you sure you want to continue connecting (yes/no)? David
That is just stating that ssh currently does not know the RSA/DSA public key for machine in which your logging into, and therefor is asking you if it's the right fingerprint. Which it will save for later use. It's normal. After the first time connecting to a host that messages goes away.

David-- This is not an error (in your case), but simply a warning condition. OpenSSH is properly warning you that the host you are trying to contact is not "known" to it, and that it cannot otherwise verify that you are in fact connecting to the host you think you are. This is a feature, designed to keep you from accidentally supplying your login/password information to an improper or impostor host. RTFM, apropos make-ssh-known-hosts(1). Alternatively, if you're sure that you *really* are connecting to the desired host, just answer "yes" to that warning and it will appropriately populate your known-hosts file. Hope this helps, and congratulations on choosing to install SSH and improve your security. --Rip Rip Loomis Voice Number: (410) 953-6874 -------------------------------------------------------- Security Engineer Center for Information Security Technology Science Applications International Corporation http://www.cist.saic.com -----Original Message----- From: owner-openssh-unix-dev at mindrot.org [mailto:owner-openssh-unix-dev at mindrot.org]On Behalf Of Higdon, David M - CNF Sent: Thursday, July 20, 2000 10:43 AM To: 'openssh-unix-dev at mindrot.org' Subject: First time install This is my first time installing ssh and I am getting the following error: $ ssh <hostname> The authenticity of host <hostname> can't be established.

Ben, thanks for your response. My problem is that after I answer yes to continue I am able to snoop my passwd over the network. - David -----Original Message----- From: Ben Lindstrom [mailto:mouring at pconline.com] Sent: Thursday, July 20, 2000 7:48 AM To: Higdon, David M - CNF Cc: 'openssh-unix-dev at mindrot.org' Subject: Re: First time install That is just stating that ssh currently does not know the RSA/DSA public key for machine in which your logging into, and therefor is asking you if it's the right fingerprint.
