SSH Key-Gen

Hello,

I am trying to set up a SSH key between servers so no password is required when I have to "scp" files between the two.

This is what I have tried so far but still requires a password:

Code:

ssh-keygen -t rsa
scp /home/<user>/.ssh/id_rsa <server2.com>:/home/<user>/.ssh/athorized_keys

When I scp after this I wasn't expecting to need a password but it is still prompting. Now I have used this same method before and it has worked great. The only difference this time is server2 is not in the same cage.

Is there something I might be doing wrong?

Thanks

Code:

~/.ssh/id_rsa.pub
             Contains the protocol version 2 RSA public key for authentica-
             tion.  The contents of this file should be added to
             ~/.ssh/authorized_keys on all machines where the user wishes to
             log in using public key authentication.  There is no need to keep
             the contents of this file secret.

I have verified that the key is in the authorized_keys file. When I turn on debugging for scp it shows it offering the rsa public keys but then proceeds to the next step like it was not accepted.

Just out of curiosity, did you generate your key to require a passphrase? I usually don't, and haven't had the problem you describe.

I usually use a script that Fedora provides 'ssh-copy-id' to install the key on the remote machine too, if you have that script you might give it a try.
